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. The cause is generally unknown, but a viral illness has been reported prior to multiple evanescent white dot syndrom in one-third of cases. [2]
The Chandler variant of ICE is characterized by pathology on the inner surface of the cornea leading to abnormal endothelial pump function. [2] [5] Other features include possible mild iris changes, corneal edema, and normal to slight elevations in intraocular pressure. [1] [5] Cogan-Reese variant is characterized by multiple pigmented iris ...
Hutchinson's sign is a clinical sign which may refer to: . Hutchinson's pupil, an unresponsive and enlarged pupil on the side of an intracranial mass; Vesicles on the tip of the nose, or vesicles on the side of the nose, precedes the development of ophthalmic herpes zoster. [1]
Ocular neuropathic pain, also called corneal neuralgia, is a spectrum of disorders of ocular pain which are caused by damage or disease affecting the nerves. Ocular neuropathic pain is frequently associated with damaged or dysfunctional corneal nerves, [ 1 ] but the condition can also be caused by peripheral or centralized sensitization. [ 2 ]
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 .
Fuchs heterochromic iridocyclitis (FHI) is a chronic unilateral uveitis appearing with the triad of heterochromia, predisposition to cataract and glaucoma, and keratitic precipitates on the posterior corneal surface. Patients are often asymptomatic and the disease is often discovered through investigation of the cause of the heterochromia or ...
If untreated, xerophthalmia can lead to dry eye syndrome, corneal ulceration, and ultimately to blindness as a result of corneal and retinal damage. Xerophthalmia usually implies a destructive dryness of the conjunctival epithelium due to dietary vitamin A deficiency—a rare condition in developed countries, but still causing much damage in ...
Whilst hearing loss is a common symptom in many diseases of the ear, for example in otosclerosis (abnormal bone growth in the ear), [3] the white, chalky patches on the tympanic membrane are fairly characteristic of tympanosclerosis. Cholesteatoma is similar in appearance but the whiteness is behind the tympanic membrane, rather than inside.
