Less frequently, rhegmatogenous retinal detachments can occur without PVD. Risk factors for retinal detachment that are not related to PVD include: Family history of retinal detachment [10] Previous retinal detachment in the other eye [8] [9] [10] Lattice degeneration: Thinning of the retina, which increases its susceptibility to breaks or tears.
Aqueous cells without the signs of uveitis, elevated intraocular pressure and rhegmatogenous retinal detachment with tears around the ora serrata are the main signs of Schwartz–Matsuo syndrome. [1] Intra ocular pressure can be as high as 60–70 mm Hg and is responsive to aqueous suppressants. [ 3 ]
During rhegmatogenous retinal detachment, fluid from the vitreous humor enters a retinal hole. The mechanisms by which retinal holes or tears form are not fully understood yet. The accumulation of fluid in the subretinal space and the tractional force of the vitreous on the retina result in rhegmatogenous retinal detachment.
[10] Those areas infected by cytomegalovirus have cells evolve to necrosis, though inflammation within the retina is not great. Rhegmatogenous retinal detachments can occur following the development of holes in areas of healed retinitis (retina may be atrophic). [11] [12] Proliferative vitreoretinopathy has been observed in cases of retinal ...
Alterations in receptor distribution can be the result of epiretinal membrane, neuroretina detachment and/or re-attachment, or retinoschisis. Macropsia caused by surgical re-attachment of macula-off rhegmatogenous retinal detachment is not symmetrical around the fovea, resulting in differences size changes in the horizontal and vertical ...
Mutation at the 6th position of the beta chain is the cause of sickle cell disease. [10] Due to sickle cell disease, vascular occlusion may occur in the conjunctiva, iris, retina, or choroid. Retinal changes occur due to blockage of retinal blood vessels by abnormal RBCs. [12]
Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
The ischemic retina releases a variety of factors, the most important of which is vascular endothelial growth factor (VEGF). These factors stimulate the formation of new blood vessels (angiogenesis). These new vessels do not have the same characteristics as the blood vessels originally formed in the eye.
