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 .
Photopsia can present as retinal detachment when examined by an optometrist or ophthalmologist. However, it can also be a sign of uveal melanoma. This condition is extremely rare (affecting 5–7 per 1 million people, typically fair-skinned, blue-eyed northern Europeans). Photopsia should be investigated immediately.
Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4] Retinal detachment is a medical emergency that requires surgery. [2] [3]
A case of Coats' disease, showing total exudative retinal detachment, and subretinal exudate containing cholesterol crystals (H&E) Microscopically, the wall of retinal vessels may be thickened in some cases, while in other cases the wall may be thinned with irregular dilatation of the lumen. [ 10 ]
Referred to as a form of retinal myopathies, cotton wools spots are commonly found to be a secondary manifestation to diseases like diabetes, hypertension, and AIDS. [1] Cotton wool spots have become one of the hallmarks of pre-proliferative diabetic retinopathy , a condition caused by damaged blood vessels in the retina due to high blood sugar ...
The risk of retinal detachment is the greatest in the first 6 weeks following a vitreous detachment, but can occur over 3 months after the event.. The risk of retinal tears and detachment associated with vitreous detachment is higher in patients with myopic retinal degeneration, lattice degeneration, and a familial or personal history of previous retinal tears/detachment.
A blurred or gray spot in the central visual field is common when the retina is detached. Reduced visual acuity may persist after the fluid has disappeared. [1] The disease is considered of unknown cause. It mostly affects white males in the age group 20 to 50 (male:female ratio 6:1) [3] and occasionally other groups.
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).
