18^th International Conference on Ophthalmology and Vision Science December 15-16, 2023 Amsterdam, Netherlands

To help you see better, contact lenses are little, transparent discs that you wear in your eyes. On the tear film that protects your cornea, contacts float.
Contact lenses are used to treat refractive defects that affect vision. When the eye does not properly bend or focus light into the eye, this is known as a refractive error and results in a blurry image.

For those with the following refractive defects, contacts can enhance vision:

Myopia (nearsightedness) (nearsightedness)
hyperopia (farsightedness) (farsightedness)
astigmatism (distorted vision) (distorted vision)
presbyopia (changes to near eyesight that generally occur with ageing) (changes to near vision that normally happen with age)

Contact lens categories: Numerous types of plastic are used to create contacts.

Hard-wearing contact lenses come in two main categories: hard and soft. Hard-wearing contact lenses are rigid gas-permeable (RGP) lenses, the most common kind of hard contact lens. Most often, plastic and other materials are used to make these lenses. They firmly maintain their shape while allowing oxygen to reach your eye through the lens. RGP lenses are particularly beneficial for those who have keratoconus and astigmatism. This is because, in cases when the cornea is unevenly bent, they offer vision that is sharper than soft lenses. RGP lenses may also be preferred by those with allergies or contact lens protein deposits.

soft contact lenses. The majority of people opt to wear soft contacts. This is because there are many possibilities, and they often tend to be more comfortable.

Conditions of the eye that affect the ocular surface are referred to as external and corneal disorders. Dry eye, blepharitis, allergies, conjunctivitis, corneal infections, and corneal dystrophies, which can result in corneal clouding, are a few of the prevalent disorders that impact the ocular surface. Allergies: Eye allergies are very common, particularly those brought on by pollen and other environmental allergens, contact allergies, drug interactions, and the use of contact lenses. Itching is the main symptom, but there may also be redness, burning, and watery discharge.

Blepharitis
A chronic eye condition called blepharitis is frequently characterised by inflammation of the eyelids. It may also result in symptoms including impaired vision, red, burning, or irritated eyes, light sensitivity, and more. Your doctor may advise using antibiotics, eye drops, or ointments to treat blepharitis, which can be brought on by bacteria or a skin problem.

Conjunctivitis (Pink Eye)
The term "conjunctivitis" describes a wide range of illnesses and ailments that can result in eyelid mucous membrane swelling, burning, and redness, as well as watery or thick discharge (the sclera). Typically mild, conjunctivitis can also be severe. It occasionally spreads quickly and affects millions of Americans at once. Viruses are frequently to blame, although germs, allergies, environmental irritants, contact lens solutions, or eye drops can also be to blame.

Corneal  Infections
Rare infections may be brought on by bacteria or fungi from a contaminated contact lens, as well as trauma-induced injury to the cornea. These infections result in swelling and drainage, can impair vision, and can thin and damage the cornea, which may necessitate a corneal transplant.

Corneal Dystrophies
The usual clarity of the cornea is diminished in disorders known as corneal dystrophies as a result of an accumulation of aberrant deposits in the cornea. There are more than 20 corneal dystrophies that can harm the entire cornea. These conditions frequently run in families, affect both eyes, and are not brought on by external causes like trauma or food. The majority of corneal dystrophies develop gradually and affect people who are otherwise healthy.

Dry Eye
Dry eye is a condition in which either the tear film is not balanced properly or the eye cannot generate enough tears to keep itself adequately moist. Millions of people throughout the world are affected by this highly prevalent diagnosis. The Dry Eye Center at UConn Health is staffed by experienced ophthalmologists who can swiftly identify and treat patients' dry eyes.

Keratoconus
A condition known as keratoconus occurs when the normally dome-shaped and spherical cornea thins in one spot and takes on a cone-like form. Clear vision depends on the cornea's ability to focus or refractively bend light onto the retina.

With age, our vision typically deteriorates. In addition to this natural ageing process, people might have eye conditions that damage their eyesight or even cause them to become blind. One of the more frequent eye illnesses is glaucoma. In the industrialised world, it is thought that 2 out of 100 adults over the age of 40 suffer from glaucoma. There are several different eye disorders that fall under the umbrella name "glaucoma," all of which include damage to the optic nerve. Ever-widening visual gaps are caused by this deterioration, which is typically initially undetectable. Your field of vision is the area that is visible to you when you stare straight ahead without adjusting your eyes.Your visual acuity (the ability to focus on details) also deteriorates in laterstages.
A kind of glaucoma known as open-angle glaucoma affects more than 90% of sufferers. Since this kind develops gradually, visual issues are not brought on by optic nerve damage for many years. The most popular treatments are eye drops and surgery.Angle-closure glaucoma is less frequent and can develop slowly for a long time before suddenly causing serious vision loss and other issues

The inaugural World Report on Vision was released by the WHO in October 2019. This study estimates that at least 2 billion individuals worldwide live with vision impairment, blindness, or disability. Vision impairment and ocular illness are huge global disease burdens that are still increasing. Ophthalmologists in every country deal with ongoing difficulties in complicated eye disease diagnosis and treatment. Thus, it is crucial that we collaborate globally and share information to increase our clinical and practical research expertise to safeguard eye health. Because of the eye's distinctive design and complex visual system,
 it is inevitable that ophthalmic research will incorporate ideas and methods from related areas. Materials science is one of these; biomechanics, neuroscience, medical imaging, and communications Internet methods, etc. Ophthalmology has developed quickly in recent years, and recently, numerous original and cutting-edge technologies and cutting-edge dis-interdisciplinary research have also developed, as have coveries.
Ophthalmologists and fundamental scientists want a sophisticated, readily available,
 

In total, there are 370 million Indigenous people living in 90 different countries. Native Americans had worse health than non-Native Americans, including higher incidences of preventable vision impairment. Service delivery strategies are used in nations like Australia and Canada to increase Indigenous peoples' access to eye care. To make it easier for Indigenous people in high-income nations to get eye care, we will perform a scoping review to find and summarise these service delivery options.

Methods and analysis

Searches on MedLINE, Embase, and Global Health will be done by an information professional. No language restrictions will be applied as we search all databases back to their creation. We'll conduct a search of the grey literature using the websites of pertinent governmental and service-providing organisations. To find further papers, field specialists will be contacted. Reference lists of pertinent articles will also be explored. All quantitative and qualitative study approaches that outline a strategy for providing eye care services to Indigenous populations will be considered. Titles, abstracts, and full-text publications will be independently reviewed by two reviewers, and data extraction will be completed. We will gather information on each service delivery model's context, inputs, outputs, Indigenous engagement, and supporting health system operations. We will extract information from where models were assessed. Using thematic analysis and descriptive statistics, we shall summarise the results.

Ethics and dissemination

We will only review published and publicly available data. Therefore, ethical approval is not necessary. The goal of this review is to help Mori in Aotearoa, New Zealand have better access to eye care services. In New Zealand and other high-income nations with Indigenous populations, the findings will be helpful to politicians, managers of health systems, and physicians who are in charge of providing eye care services. In addition to publishing our findings in a peer-reviewed publication, we will create an easily readable summary of the findings for posting on the website and presenting them at stakeholder meetings.

In-office management and treatment of retinal illnesses are the focus of the ophthalmology subspecialty known as medical retina. Age-related macular degeneration (AMD), diabetic retinopathy, hypertensive retinopathy, vitreous floaters, retinal vascular disorders, retinal tears, and a few different types of retinal detachments are among the conditions that can affect the retina. The retina is the tissue lining the inner surface of the back of the eye. For one to have central vision (such as seeing people's faces and sports scores on TV), the macula, located in the middle of the retina, is crucial. Although retinal illness can be severe and vision-threatening, recent advancements in the field have increased our ability to properly treat these issues

Both neurology and ophthalmology have a specialisation called neuro-ophthalmology. Eye specialists known as "neuro ophthalmologists" focus on nervous system-related vision issues. These problems include vision abnormalities brought on by diseases or brain disorders such as trauma, a stroke, or infection. A neuro-ophthalmologist can diagnose and treat neurological and systemic diseases that impair your sight and the movement of your eyes. While sometimes these problems may not be major causes for concern, other times they might result in more serious complications, such as vision loss. They might perform electroretinography, optical coherence tomography, and multi-focal EGRs on you.

The appearance of fundamental ocular structures, including the external eye, anterior segment, and retina, can be recorded over the course of research by highly skilled OSOD ophthalmologists and imaging specialists. The anterior and posterior segments can be imaged in colour using fluorescein angiography, fundus autofluorescence, and cross-sectional imaging techniques thanks to modern digital cameras, cutting-edge imaging equipment, and sophisticated imaging techniques. The imaging team at OSOD is made up of highly qualified individuals, many of whom regularly take clinical pictures of patients. Many have educated or qualified many of the photographers who have taken part in extensive human scientific research; therefore, they are also great teachers.
When conducting research at Labcorp or at a university, OSOD has the option of using either film or digital imaging modalities. A retinal specialist at OSOD evaluates and grades each and every colour fundus photograph, fluorescein angiography, and OCT imaging.

In ocular oncology, tumours that develop in or around the eyes are studied and treated. Due to the complexity of ocular oncology, our faculty comprises specialists in cornea, ophthalmic plastic surgery, pathology, and retina. These tumours may cause vision loss or loss of the eye itself, and they can range from benign to potentially fatal. Mass. Researchers and clinician scientists at the Eye and Ear Institute have expertise in a variety of disorders, such as retinoblastoma, orbital tumours and inflammation, uveal melanoma, and ocular surface tumours

In 1955, the first two years of medical school were lecture-based, while the final two years of medical school were increasingly clinical, following the advice of Flexner from 45 years earlier. Learning objectives, formative assessments, and a specified curriculum were nonexistent. In my biochemistry course, which lasted two thirds of the year and had one summative evaluation, as an example, this was the case. There was a hierarchical structure, and we had grades, like other schools. It was common for the graduating class to lose a significant number of members over the anticipated four years at that time, 1959. In my case, out of the 120 incoming freshmen, 89 of them graduated, including 3 from earlier entering classes.

A "rotating" internship was chosen if you weren't sure what speciality you wanted to pursue in the future (at least 8 people in my class didn't pursue residency programmes). My experience was on the West Coast in a county hospital with significant intern responsibilities, knife and gun victims, and a wide range of uncommon and challenging cases. Coming from a Midwest medical school that was very didactic but trauma-free, it was a fantastic opportunity. In contrast to my experience in Iowa, the people were mostly illiterate and impoverished. About six years later, I was able to use my knowledge and abilities to take over as the triage officer of an evacuation hospital in Vietnam. Both clearly defined traditional educational standards, such as a curriculum, and properly structured assessments were absent. .  I was given the option to choose between an internal medicine residency, a surgical residency, and an ophthalmology residency at the Highland Alameda County Hospital in Oakland, California, but I chose none of the above. Although the education in Iowa was far better, I wasn't yet ready to go.

Ophthalmic Epidemiology is committed to publishing innovative studies on the health of the eyes and vision in the areas of epidemiology, public health, and the avoidance of blindness. On all topics connected to ophthalmic epidemiology, Ophthalmic Epidemiology publishes editorials, original research reports, systematic reviews and meta-analysis articles, brief communications, and letters to the editor. It is acceptable to discuss a wide range of subjects, including: assessing the risk of ocular diseases; general and specific study designs; implementation and evaluation of screening programmes; access to, delivery of, and outcomes from eye health care; therapeutic efficacy or effectiveness; disease prognosis and quality of life; cost-benefit analysis; biostatistical theory; and risk factor analysis. We want to engage with international news stories more frequently, particularly those that deal with issues that affect developing nations. even though international reporting might be appropriate. For this journal, animal study reports, brief case series (insufficient for a cohort analysis), and clinical case reports are not acceptable for publication

To accurately diagnose the illness, ophthalmic pathologists examine the tissues that eye doctors have removed. Using macroscopy and light microscopy, the diseased tissue is analysed. It's also not uncommon to use other methods, including electron microscopy, molecular testing, and immunohistochemistry. A critical component of patient treatment is the disease diagnosis. When it comes to the cause, pathophysiology, and prognosis of eye illnesses, ophthalmic pathologists are able to provide the practising ophthalmologist with a tissue diagnosis. Because of their extensive understanding of eye illnesses, ophthalmic pathologists are a crucial part of academic medical institutes. They help to maintain the provision of high-quality eye care by instructing ophthalmologists and trainees in ophthalmology (residents and medical students).

Due to their extensive understanding of eye illnesses, ophthalmic pathologists play a crucial role in academic medical institutes. They help to maintain high quality eye care by instructing residents and medical students as well as practising ophthalmologists and trainees in ophthalmology. There are many ophthalmology training programmes in the USA. John G. Clarkson's editorial, "Ophthalmic Pathology: Important Now and in the Future," acknowledged the value of ophthalmic pathology in education. In addition to their work in teaching and diagnosing eye diseases, ophthalmic pathologists also conduct research that advances our understanding of these conditions.

In the developed world, ocular trauma is one of the most under-recognized causes of vision loss. Cataract or glaucoma may develop as a result of blunt or penetrating ocular trauma (Figures 1 and 2). Etiologies of ocular injury vary across urban and rural locations; between different geographical regions of the world; and between various demographic or socioeconomic strata. They also vary from country to country. Remote trauma and the challenge of getting a reliable history might make epidemiological research challenging. Trials to enhance managerial understanding may also be constrained by inadequate follow-up. Understanding the cause or mechanism of injury is necessary for developing preventative strategies for ocular trauma since it may help to better allocate resources for preventing such injuries. There is a heavy, potentially avoidable burden placed on society and the victims of eye injuries.

Oculoplastic and orbital surgery targets the structures around the eye, such as the eyelids, orbit (the bones of the eye socket), lacrimal system (the system of tear ducts), forehead, and midface region. The oculoplastic and orbital surgeons at UT Southwestern are skilled ophthalmologists with years of experience in the most recent plastic surgical techniques. Because surgery in these areas might influence vision, ophthalmic plastic surgeons are best suited to perform this sensitive operation. Our oculoplastic surgery staff offers both surgical and nonsurgical cosmetic operations to improve your appearance, in addition to treating diseases, disorders, and accidents affecting the eyes, eyelids, and surrounding structures. .  offers a thorough evaluation, medicinal and surgical therapy, and care for abnormalities of the eyelids, brows, tear duct, and diseases of the orbit, such as thyroid eye disease and traumatic "blowout" fractures of the orbit. This practise specialises in aesthetic surgery, which includes eyelid surgery, laser skin resurfacing for blemishes and wrinkles, and hair removal.

The condition of having crossed eyes, or strabismus, causes the eyes to not line up properly. To put it another way, one eye is directed in a direction that the other eye is not. When everything is normal, the six muscles that control eye movement coordinate to point both eyes in the same direction. Strabismus patients struggle to regulate their eye movements and maintain appropriate ocular alignment (eye position). The direction that the twisted or misaligned eye is facing can be used to classify strabismus:
turning inward (esotropia)
turning away from (exotropia)
turning upward (hypertropia)
turning downward (hypotropia)

Additional elements to take into account when figuring out the cause and course of action for strabismus include:
Was the issue gradual or did it start out suddenly? 
Did it start within the first six months of life, or did it start later? 
Is the eye that is affected always the same, or does it alternate? 
Is the degree of turning slight, medium, or severe? 
Is it constantly present or just occasionally? 
Has strabismus run in the family?

Pediatric Ophthalmology

According to estimates, 1.4 million of the 45 million blind people on the globe in 2000 were youngsters from middle-and low-income nations, the majority of whom reside in the most underdeveloped parts of Africa and Asia. This paper's main objective is to discuss the state of paediatric ophthalmology in developing nations and the advancements made in the fight against preventable childhood blindness and visual impairment, particularly corneal scarring brought on by vitamin A deficiency, congenital cataract, and retinopathy of prematurity. We will also go over the prevalence of uncorrected refractive errors and talk about how accessible paediatric ophthalmologists are in poor nations.

Recent findings

Some poor nations have started using vitamin A supplements and measles vaccinations and have noticed a reduction in xerophthtalmia. The prevalence of cataract as a curable cause of childhood blindness is increasing as vitamin A status improves. Amblyopia and untreated refractive abnormalities, with myopia being the most prevalent, are significant and easily treated causes of visual impairment. Retinopathy of prematurity is becoming an important cause of juvenile blindness as neonatal intensive care services in middle-income developing countries increase the survival of preterm children.

Summery

In developing nations, childhood blindness and visual impairment are still serious public health problems, although recent initiatives have offered hope for future progress.

Introduction

Ocular surgery enables refractive defects to be permanently repaired in a reliable, safe, and safe manner with few problems.

Methods

review of the relevant literature, with particular emphasis on the German Commission for Refractive Surgery's recommendations

Results

Laser in-situ keratomileusis (LASIK) is the most widely used refractive surgical procedure in the world, having been used in about 18 million treatments to date. Surface ablation techniques (PRK, LASEK, Epi-LASIK) and the implantation of phakic intraocular lenses are alternatives to LASIK. Myopia, hyperopia, and presbyopia can be treated alternatively if ocular accommodation is lost by removing the crystalline lens and implanting contemporary multifocal intraocular lenses (refractive lens exchange).

Discussion

Strict inclusion criteria are used and a high technical quality is upheld throughout the procedure to enhance the treatment impact and minimise problems.

Uveitis is a form of eye inflammation. It affects the middle layer of tissue in the eye wall (uvea). Uveitis warning signs often come on suddenly and get worse quickly. They include eye redness, pain, and blurred vision. The condition can affect one or both eyes, and it can affect people of all ages, even children.Possible causes of uveitis are infection, injury, or an autoimmune or inflammatory disease. Many times the cause can't be identified. Uveitis can be serious, leading to permanent vision loss. Early diagnosis and treatment are important to prevent complications and preserve your vision.

Symptoms

The signs, symptoms, and characteristics of uveitis may include:

• Eye redness
• Eye pain
• Light sensitivity
• Blurred vision
• Dark, floating spots in your field of vision (floaters)
• Decreased vision

Although they can appear unexpectedly and worsen quickly, symptoms can also develop gradually. One or both eyes may be affected. The uvea is the middle layer of tissue in the eye's wall. Sometimes there are no symptoms, but uveitis symptoms can be seen during a normal eye checkup. It is made up of the iris, ciliary body, and choroid. The coloured portion of the eye, known as the iris, is found inside the front of the eye. When you look at your eye in the mirror, you will notice the white section of the eye, known as the sclera. The structure behind the iris is called the ciliary body. A layer of blood vessels called the choroid lies between the retina and the sclera.

Depending on which area(s) of the eye are inflamed, you may have one of the following types of uveitis:

•The ciliary body and the interior of the front of your eye (between the cornea and the iris) are both impacted by anterior uveitis. The most common kind of uveitis is known as iritis.
•The retina, the pars plana blood vessels behind the lens, and the gel in the middle of the eye are all impacted by intermediate uveitis (vitreous).
•Posterior uveitis affects the retina or choroid, two layers on the inside of the back of your eye.
•Panuveitis happens when your eye's entire uvea, from the front to the rear, becomes inflamed.
When to consult a doctor: If you believe you are exhibiting the symptoms of uveitis, speak with your doctor. He or she may suggest that you see an eye doctor (ophthalmologist). Seek emergency medical assistance if you experience severe eye pain or if you experience any sudden changes in your eyes

Rehabilitation for those with low vision is the norm in terms of medical care. A low vision rehabilitation programme may be available if you or someone you know has a vision problem. People with low vision can learn a number of skills to assist them in performing daily tasks with their remaining eyesight, and a doctor of optometry who offers low-vision rehabilitation services can help them restore their independence and enhance their quality of life. The American Academy of Ophthalmology and the American Optometric Association have both urged Medicare to fund low-vision rehabilitation services since 1999. Government and commercial organisations also include occupational therapy, rehabilitation training, and educational and career counselling. Nowadays, many Medicare providers have plans that cover some services for vision rehabilitation.

Since 1924, original research has been published monthly in Vision Science, a peer-reviewed scientific journal of the American Academy of Optometry. Optometry and Vision Science is a world-renowned resource for education and information on recent advances in optometry, physiological optics, vision science, and related fields. The publication takes into account novel contributions that promote clinical practise, vision science, and public health. Authors should keep in mind that the journal has readers all over the world; therefore, their articles should be pertinent and interesting to a large audience. Topical priorities consist of, but are not restricted to: clinical and laboratory research; evidence-based reviews; contact lenses; ocular growth and refractive error development; eye movements; visual function and perception; biology of the eye and ocular disease; epidemiology and public health; biomedical optics and instrumentation
