Retinoschisis is an eye disease characterized by the abnormal splitting of the retina's neurosensory layers, usually in the outer plexiform layer.Retinoschisis can be divided into degenerative forms which are very common and almost exclusively involve the peripheral retina and hereditary forms which are rare and involve the central retina and sometimes the peripheral retina.
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]
The American Academy of Ophthalmology notes though retinal detachment is associated with lattice degeneration, lattice degeneration is not as strongly associated with or predictive of retinal detachment, with one study finding a low overall risk of developing retinal detachment at around 0.3–0.5%. [2]
Central retinal artery occlusion: CRAO is characterized by painless, acute vision loss in one eye. [11] Central retinal vein occlusion: CRVO causes sudden, painless vision loss that can be mild to severe. [12] Branch retinal vein occlusion: sudden painless vision loss or visual field defect are the main symptom of BRVO. [13]
Using a laser, an ophthalmologist burns the portions of the retina that are not supported by blood vessels, a technique known as laser photocoagulation. [1] By doing so, this tissue will no longer release molecules that stimulate blood vessel growth. If a retinal detachment occurs, laser therapy or surgery may be required to repair the retina ...
Retinal detachment: NOS; without retinal break Excludes: central serous chorioretinopathy (H35.7) (H33.3) Retinal breaks without detachment Horseshoe tear of retina, without detachment; Round hole of retina, without detachment; Operculum; Retinal break NOS Excludes: chorioretinal scars after surgery for detachment (H59.8) peripheral retinal ...
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.
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).
