Amblyopia
|
Dullness of vision; reduced or dimness of vision; also called lazy eye
|
|
Anisocoria
|
Condition in which the pupils are unequal
|
|
Aphakia
|
Condition in which the crystalline lens is absent
|
|
Astigmatism
|
Defect in the refractive powers of the eye, due to a misshapen curvature of the cornea and lens, in which a ray of light is not focused on the retina but is spread over an area
|
|
Blepharitis
|
Inflammation of the hair follicles and glands along the edges of the eyelids
|
|
Blepharoptosis
|
Drooping of the upper eyelid(s)
|
|
Cataract
|
Opacity of the crystalline lens or its capsule; most often occurs in adults past middle age. Types of Cataract: Age-related; Congenital (don’t necessarily affect vision but if so, has to be removed; Secondary cataract= more likely to develop in people who have certain other health problems e.g. diabetes. Also, cataracts sometimes linked to steroid use.; Traumatic cataract=develops soon after an eye injury or years later. Commonest surgery to remove cataract is PHACOEMULSIFICATION.
|
|
Choroiditis
|
Inflammation of the vascular coat of the eye
|
|
Conjunctivitis.
|
Inflammation of the conjunctiva caused by allergy, trauma, chemical injury, bacterial, viral, or rickettsial infection. Type pinkeye is infectious and contagious. Diagnosed through eye exam and taking sample of fluid from eyelid using cotton swab. Bacteria or viruses that could cause conjunctivitis can be seen through microscope. Treatment based on cause. Bacterial infection-antibiotic eye drops or ointments. If topical antibiotics do not solve problem, oral antibiotics used. Cause allergy-use eyedrops containing antihistamines, nonsteroidal antinflammatory agents, or corticosteroids. Cause foreign matter-foreign matter removed.
|
|
Cycloplegia
|
Paralysis of the ciliary muscle
cyclo=cilliary body -plegia=paralysis/stroke |
|
Dacryoma
|
Tumorlike swelling caused by obstruction of the tear duct(s)
|
|
Diplopia
|
Double vision
|
|
Entropion
|
Turning inward of the margin of the lower eyelid.
|
|
Esotropia (ST)
|
Condition in which the eye or eyes turn inward; also called crossed eyes
|
|
Exotropia (XT)
|
Turning outward of one or both eyes.
|
|
Hemianopia
|
Inability (blindness) to see half the field of vision.
|
|
Hyperopia
|
Vision defect in which parallel rays come to a focus beyond the retina; also called farsightedness
|
|
Iridocyclitis
|
Inflammation of the iris and ciliary body
|
|
Keratitis
|
Inflammation of the cornea
|
|
Keratoconjunctivitis.
|
Inflammation of the cornea and the conjunctiva.
|
|
Macular degeneration
|
Degeneration of the macular area of the retina-area important in the visualization of fine details.
|
|
Myopia (MY)
|
Vision defect in which parallel rays come to focus in front of the retina; nearsightedness.
|
|
Nyctalopia
|
Condition in which the individual has difficulty seeing at night; also known as night blindness
|
|
Phacosclerosis
|
Condition of hardening of the crystalline lens
|
|
Photophobia
|
Unusual intolerance of light
|
|
Presbyopia
|
Vision defect in which parallel rays come to a focus beyond the retina; occurs normally with aging; also known as farsightedness
|
|
Retinal detachment
|
Separation of the retina from the choroid layer of the eye that can be caused by trauma or can occur spontaneously
|
|
Retinitis
|
Inflammation of the retina
|
|
Retinitis pigmentosa
|
Chronic progressive disease marked by bilateral primary degeneration of the retina beginning in childhood and leading to blindness by middle age. Night blindness and a reduced field of vision are early clinical signs of this disease.
|
|
Retinoblastoma
|
Malignant tumor arising from the germ cell of the retina
|
|
Retinopathy
|
Any disease of the retina
|
|
Retrolental fibroplasia (RLF)
|
Disease of the retinal vessels present in premature infants; can be caused by excessive use of oxygen in the incubator; can cause retinal detachment and blindness.
|
|
Scleritis
|
Inflammation of the sclera
|
|
Stargardt's disease/juvenile macular degeneration
|
Inherited disease that affects 1 in 10,000 people. Usually manfests itself between ages of 7-12 years. Current theory - Stargardt's disease causes eye's central vision to deteriorate because rod cells just outside the macula erode which eventually harms retinal pigment epithelium (RPE). As the RPE fails, the disease can spread to macula's cone cells, causing macular degeneration's characteristic loss of central vision. Vision loss slow until 20/40 level, and then rapidly progresses to 20/200 level. Sometimes vision can degenerate to 10/200 in a period of months. Peripheral vision generally remains.
|
|
Strabismus/Squint.
|
Disorder of the eye in which the optic axes cannot be directed to the same object.
|
|
Stye/Hordeolum.
|
Inflammation of one or more of the sebaceous glands of the eyelid.

|
Uveitis
|
Inflammation of the uvea (consists of the iris, ciliary body, and choroid, and forms the pigmented layer)
|
|
