Diseases of the Eye
Glaucoma is a disease in which the pressure of the fluid inside the eye is too high, resulting in a loss of peripheral vision.
Blepharitis is an ocular disease characterized by inflammation of the eyelid margins. Blepharitis may cause redness of the eyes, itching and irritation of the eyelids in one or both eyes. Its appearance is often confused with conjunctivitis and due to its recurring nature it is the most common cause of "recurrent conjunctivitis" in older people. It is also often mistaken for "dry eye" by patients due to the gritty sensation that may occur, however lubricating drops do little to improve the condition.
A chalazion is a cyst in the eyelid that is caused by inflammation of a blocked meibomian gland, usually on the upper eyelid. Chalazions differ from styes in that they are usually painless apart from the tenderness caused when they swell up, and in size. A chalazion may eventually disappear on its own after a few months, though more often than not, some treatment is necessary.
Conjunctivitis, commonly called "Pink Eye" or "Red Eye" is an inflammation of the conjunctiva (the outermost layer of the eye and the inner surface of the eyelids), most commonly due to an allergic reaction or an infection.
Dry Eye syndrome (DES), or simply dry eyes, is an eye disease caused by decreased tear production or increased tear film.
A Pinguecula is a raised, yellowish thickening of the white part of the eye. Excessive sun exposure is a common cause. This condition is usually treated with artificial tears to decrease dryness. Sunglasses are helpful in preventing further growth.
A Pterygium is a growth on the conjunctiv cornea that can cause irregular astigmatism and/or warping of the cornea. If large enough, the growth will block light entering the eye and may lead to vision loss. In severe cases, an outpatient procedure may be considered to remove the tissue.
Keratoconus is a degenerative disorder of
the eye in which structural changes within the cornea cause it
to thin and change to a more conical shape than its normal
Strabismus is a condition in which the eyes are not properly aligned with each other. It typically involves a lack of coordination between the extraocular muscles that prevents bringing the gaze of each eye to the same point in space and preventing proper binocular vision, which may adversely affect depth perception.
A stye is an infection of the sebaceous glands at the base of the eyelashes. While they produce no lasting damage, styes can be quite painful.
A subconjunctival hemorrhage is bleeding underneath the conjunctiva. The conjunctiva contains many small, fragile blood vessels that are easily ruptured or broken. When this happens, blood leaks into the space between the conjunctiva and sclera.
