Uveitis (/ ˌ juː v i. aɪ t ɪ s /) is inflammation of the uvea, the pigmented layer of the eye between the inner retina and the outer fibrous layer composed of the sclera and cornea. [1] The uvea consists of the middle layer of pigmented vascular structures of the eye and includes the iris, ciliary body, and choroid.
Corneal smears or impression cytology specimens can be analyzed by culture, antigen detection, or fluorescent antibody testing. Tzanck smear, i.e.Papanicolaou staining of corneal smears [ further explanation needed ] , show multinucleated giant cells and intranuclear inclusion bodies, however, the test is low in sensitivity and specificity.
Multiple evanescent white dot syndrome occurs mostly in females. Symptoms include a sudden loss of central vision, but patients eventually regain normal vision. The white dots are small and located in the posterior pole at the level of the retinal pigment epithelium. The white dots may disappear after the first few weeks of the disease.

Photokeratitis is known by a number of different terms, including snow blindness , arc eye , welder's flash , sand eyes , bake eyes , corneal flash burns , flash burns , niphablepsia , or ...
Epithelial basement membrane dystrophy (EBMD) is a disorder of the eye that can cause pain and dryness.EBMD, also known as map-dot-fingerprint dystrophy and Cogan microcystic epithelial dystrophy, is a corneal epithelial disease that may result in recurrent corneal erosions, irregular corneal astigmatism, and decreased vision.
In the United States, Acanthamoeba keratitis is nearly always associated with soft contact lens use. [7] Acanthamoeba spp. is most commonly introduced to the eye by contact lenses that have been exposed to the organism through the use of contaminated lens solution, using homemade saline-based solution or tap water, or from wearing contact lenses while bathing or swimming.
Leukocoria (also white pupillary reflex) is an abnormal white reflection from the retina of the eye. Leukocoria resembles eyeshine , but leukocoria can also occur in animals that lack eyeshine because their retina lacks a tapetum lucidum .
