Retinopathy is diagnosed by an ophthalmologist or an optometrist during eye examination. The clinician will need to examine the retina, at the back of the eye, to make this diagnosis. There are several ways to examine the retina. The clinician can directly view the retina by looking through the pupil with a light.
Acute retinal necrosis (ARN) [1] is a medical inflammatory condition of the eye. [2] The condition presents itself as a necrotizing retinitis . [ 3 ] The inflammation onset is due to certain herpes viruses , varicella zoster virus (VZV), herpes simplex virus (HSV-1 and HSV-2) and Epstein–Barr virus (EBV).
A punctal plug may be inserted into the tear duct by an optometrist or ophthalmologist, decreasing the removal of natural tears from the affected eye. [8] The use of contact lenses may help prevent the abrasion during blinking lifting off the surface layer and uses thin lenses that are gas permeable to minimise reduced oxygenation.

This can lead to the growth of new blood vessels which are prone to leakage and hemorrhage and can cause retinal folds, tears, and detachments. Treatment involves laser photocoagulation of the avascular portions of the retina to reduce new blood vessel growth and risk of complications including leakage of retinal blood vessels and retinal ...
Retinal tufts can be visualized or diagnosed using a dilated eye examination and indirect ophthalmoscope or a widefield retinal scan. [3] A retinal tuft is a gliotic degeneration of the retina composed of focal adhesions in the extracellular matrix joining the retina and the posterior hyaloid of the eye.
Rhegmatogenous retinal detachment is caused by a tear or break in the retina. [6] [9] This allows vitreous humor, the fluid that normally sits in the center of the eye, to build up behind the retina. [6] [9] As a result, the retina can eventually separate from the tissues underneath it. [6] [9] [10] This is the most common type of retinal ...
Retinal hemorrhage (UK English: retinal haemorrhage) is a disorder of the eye in which bleeding occurs in the retina, the light sensitive tissue, located on the back wall of the eye. [1] There are photoreceptor cells in the retina called rods and cones , which transduce light energy into nerve signals that can be processed by the brain to form ...
