An image of an eye can reveal conditions such as glaucoma, cataracts, retinal detachment, uveitis and keratoconus, according to MedicineNet. Other conditions identified are corneal ulcers and diabetic retinopathy. Pictures of eyelids can reveal styes, blepharitis and chalazions.
Glaucoma occurs due to elevated pressure within an eye, explains MedicineNet. The elevated pressure can affect the optic nerve and cause vision loss. A cataract is a clouding of the lens that progresses slowly with age. Cataracts result in blurry vision and sometimes require surgery. Separation of the retina from underlying structures is called a retinal detachment, which requires surgery.
Uveitis is an inflammation of the uvea, the middle layers of the eye, notes MedicineNet. The uvea contains arteries and veins that feed important eye structures. Keratoconus occurs when the clear outer layer of the eye becomes weakened, resulting in a conical bulging of the eyeball. Corneal ulcers are small craters that occur on the front of the eye from infection. Diabetic retinopathy is a bleeding in the retina that occurs in some diabetics.
Styes occur when the oil gland at the base of an eyelash becomes infected, explains MedicineNet. A stye looks like a pimple on the edge of an eyelid. Blepharitis is an inflammation of the eyelids resulting from problems with oil glands, infections or skin conditions. Chalazions occur when a gland in the eyelid becomes clogged, resulting in inflammation and swelling.
