Warpage. Corneal Warpage is distortion of the corneal shape due to contact lenses especially rigid contact lenses. Patients with corneal warpage can't do corneal topography. He must take off his contact lenses for at least 1 week in soft contact lenses and 3 weeks for rigid contact lenses.


Weber Syndrome. A neurological condition that is caused by lesion to third cranial nerve as it passes through the cerebral peduncle.It is characteristic by palsy of the third cranial nerve (Oculomotor nerve) at the same side of the lesion and muscles weakness or hemiparesis on the contralateral side of the lesion. Oculomotor nerve controls most of the extraocular muscles and also the pupil.


Weill Marchesani Syndrome. It is a connective tissue disease that is inherited as autosomal dominant or autosomal recessive. It has systemic and ocular manifestations.


Weis Procedure. Surgical procedure that can be done to correct lower eyelid entropion.


Weiss Ring. Detachment of the posterior vitreous face from the margin of the optic disc.


Wernicke Hemianopic Pupil. Normal Pupillary response occurs when the unaffected retina is stimulated by light and abnormal pupillary response occurs when the affected retina is stimulated.It is a sign of a lesion to optic tract.


Wet Macular Degeneration. Wet macular degeneration occurs when new abnormal blood vessels arise from part of the eye which lies behind the retina and is called choroid.

 

 

 

White Dot Syndromes. Group of uveitic disorders that occur due to inflammation of the choriocapillaris part of the choroid. This infammation causes changes of the choroid,retinal pigment epithelial and outer retinal layers. Examples are: Multiple evanescent white dot syndrome,Serpiginous Choroidopathy and Birdshot retinochoroidopathy.


Wilson Disease. A condition which is characterized be deficiency of Ceruloplasmin. Ceruloplasmin is the major copper-carrying protein in the body.Due to this deficiency, copper will deposit in various tissue such as liver, basal ganglia of the brain, cornea and lens.Kayser Fleischer ring is a copper deposition in the cornea. Deposition in lens will cause sunflower cataract.


Window Defect. A Sign in retinal fluorescein angiography. The retinal pigment epithelial is a hypofluorescent and the underlying choroid is hyperfluorescent. Window defects are hyperfluorescent areas in retinal pigment epithelial cells due to defects in this layer. These defects will allow visualization of the underlying hyperfluorescent choroid.


Wolfram Syndrome. Rare genetic disease that is transmitted as Autosomal Recessive. It is also called DIDMOAD which is Diabetes Insipidus, Diabetes Mellitus,Optic Atrophy and Deafness.


Wyburn Mason Syndrome. Congenital Arteriovenous malformation of the retinal blood vessels with ipsilateral arteriovenous malformation of the brain.
