Cornea, External Eye Diseases, and Eye Banking

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.
