Endophthalmitis Endophthalmitis is an inflammation of the inside of the eye. The inflammation can extend to surrounding tissues responsible for vision. Macular Degeneration Macular degeneration is a common cause of blindness and vision problems among older people. Macular degeneration is also called age-related macular degeneration, or AMD. Double Vision (Diplopia) Double vision, also called diplopia, causes a person to see two images of a single object. Retinopathy Retinopathy refers to diseases that affect the retina, the collection of light-sensitive cells lining the back half of each eye. Retinal Vessel Occlusion The retina is the light-sensitive layer at the back of the eye that is responsible for vision. If an occlusion (blockage) forms, there is typically a sudden, painless loss of vision in the affected eye. Retinoblastoma Retinoblastoma is a form of cancer that develops on the retina. Although rare, retinoblastoma is the most common eye tumor in children. Choroidal Melanoma Choroidal melanoma is a cancer that affects part of the eye. It develops in the choroid, the sponge-like membrane at the back of the eye between the sclera (the white of the eye) and the retina. Astigmatism Astigmatism means that the cornea of the eye has an irregular shape, causing vision problems. Scleritis Scleritis is a potentially serious inflammation of the sclera, commonly called the white of the eye. Dislocated Lens The lens is a transparent, disk-shaped structure in the eye that focuses light onto the retina, allowing us to see clearly. A dislocated lens is a lens that has moved out of position because some or all of the supporting ligaments have broken. Cytomegalovirus Cytomegalovirus Eyelid And Tear Duct Disorders Styes and Chalazions A sty, also called hordeolum, is a small abscess of the oil gland associated with an eyelash hair follicle. A chalazion, like a sty, is a swelling within the eyelid caused by inflammation of an oil gland. Drooping Eyelid (Ptosis) In this condition, the border of the upper eyelid falls to a position that is lower than normal. In severe cases, the drooping eyelid can cover all or part of the pupil and interfere with vision. Tear Duct Infection (Dacryocystitis) Dacryocystitis is an infection in the tear ducts of the eye or in the tear sac, also called the lacrimal sac. Blepharitis Blepharitis is an inflammation of the eyelids that involves the edges of the eyelids and eyelash hair follicles. Eye Injury Black Eye A black eye, sometimes called a "shiner," is a bruise around the eye. Chemical Injury to the Eye A chemical eye injury is an emergency. Damage can occur within one to five minutes. Eye Socket Fracture (Fracture of the Orbit) A broken bone (fracture) in the eye socket can involve the rim of the socket, the floor or both. Detached Retina A detached retina, also called a retinal detachment, is a separation of the retina from the deeper layers of the eyeball that normally support and nourish it. Foreign Body in Eye Eyelashes prevent most particles or objects from entering the eye, and tears usually are able to rinse out particles that do get in the eye. Occasionally, a solid object or projectile can adhere to the eye or embed itself below the surface of the eye. Corneal Abrasion The cornea is the transparent, dome-shaped "window" that covers the front of the eye. A nick, scratch or scrape of the cornea is called a corneal abrasion. Lazy Eye Lazy Eye (Amblyopia) Lazy eye, also called amblyopia, is an eye problem that can occur in growing children. Pinkeye (Conjunctivitis) Pinkeye (Conjunctivitis) Conjunctivitis, also called pinkeye, is an inflammation of the conjunctiva, the transparent membrane that lines the eyelids and covers the whites of the eyes. Crossed Eyes (Strabismus) Crossed Eyes (Strabismus) Crossed eyes, also called strabismus, occurs when the eyes appear to be misaligned and point in different directions.
