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]
Recently, central serous chorioretinopathy has been understood to be part of the pachychoroid spectrum. [5] [6] In pachychoroid spectrum disorders, of which CSR represents stage II, the choroid, the highly vascularized layer below the retina, is thickened and congested with increased blood vessel diameter, especially in the deep choroid (the so-called Haller's layer).
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.
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]
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).
Diabetic retinopathy (also known as diabetic eye disease), is a medical condition in which damage occurs to the retina due to diabetes.It is a leading cause of blindness in developed countries and one of the lead causes of sight loss in the world, even though there are many new therapies and improved treatments for helping people live with diabetes.
Retinal diseases in dogs include retinal dysplasia, progressive retinal atrophy, and sudden acquired retinal degeneration. Lipaemia retinalis is a white appearance of the retina, and can occur by lipid deposition in lipoprotein lipase deficiency. Retinal Detachment. The neural retina occasionally detaches from the pigment epithelium.
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%.
