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: 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 ...
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 tufts increase the risk of a retinal tear or a detached retina, although the risk is not high- 1% of tufts are thought to lead to retinal detachment. [ 2 ] [ 6 ] In addition if there is retinal thinning near a zonular traction tuft, there is an increased risk of retinal detachment.
Generally, diseases outlined within the ICD-10 codes H30-H36 within Chapter VII: Diseases of the eye, adnexa should be included in this category. Wikimedia Commons has media related to Disorders of choroid and retina .
These detachments may occur at any age but most frequently present in early adulthood. The most popular theory behind this association is a separation of the layers of the retina, known as retinoschisis, due to fluid (the vitreous humour) entering the optic pit and traveling between the inner and outer layers of the retina. The outer layer may ...
Intraretinal microvascular abnormalities (IRMA) are abnormalities of the blood vessels that supply the retina of the eye, a sign of diabetic retinopathy. [1] IRMA can be difficult to distinguish from and is likely a precursor to retinal neovascularization. One way to distinguish IRMA from retinal neovascularization is to perform fluorescein ...
Diagram of the human eye showing macula and fovea. Although J. D. Gass originally identified four types of idiopathic juxtafoveolar retinal telangiectasis in 1982, contemporary researchers describe three types collectively known as idiopathic juxtafoveal telangiectasia: macular telangiectasia type 1, macular telangiectasia type 2, and macular telangiectasia type 3.
