Ophthalmological phenomena

Abstract

The term ''phenomenon'' can sometimes be miscalled equally to the terms ''sign or reflex''. However, terms ''syndrome and disease'' are not often confused with the phenomenon. Reflex is defined as '' an involuntary physical reaction or automatic response from the nerve impulse to a stimulus. 5-7 On the other hand, the term in medicine ''sign'' is any abnormal, observable evidence or physical phenomenon which often indicates dysfunction or disease. It is usually detected by the physician even if the patient cannot observe and experience it. 8,9 Regarding phenomena in ophthalmology, we fund just a publication by Sharma et al., 10 in the web. Here, following the search of the term in major academical and scientific databases and indexes, we tried to present in alphabetical order, some common phenomena in ophthalmology. Some of these are actual phenomena that we have known already before but are called differently.
