Furthermore, if the optic pit is located temporally (which the majority are), then it is more likely to cause detachment of the macula because of the macula's proximity to the temporal side of the optic disc. If serous macular detachment occurs, a patient's visual acuity may become as poor as 20/200 or worse.
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.
Other factors that can affect the prognosis include the extent of the detachment and the timing of surgery, with earlier treatment generally leading to better outcomes. [3] [16] Common causes of failure in retinal detachment repair include missed or poorly sealed retinal breaks, new retinal breaks, and proliferative vitreoretinopathy (PVR).
Pachychoroid disorders of the macula represent a group of diseases affecting the central part of the retina of the eye, the macula. Due to thickening and congestion of the highly vascularized layer underneath the macula, the choroid, damage to the retinal pigment epithelium and the retinal photoreceptor cells ensues. This leads to impaired vision.
A retrospective series of 20 patients over 10 to 21 years showed deterioration of vision in more than 84% of eyes, either due to intra-retinal edema and serous retinal detachment (Type 1) or retinal pigment epithelium (RPE) scar formation or neovascularization (Type 2).
Vitreomacular traction syndrome (VTS) is a medical condition in the eye that is the result of tractional forces (pulling) being placed on the retina. [1] [2] VTS is common in people who have an incomplete posterior vitreous detachment, a type of retinal detachment at the periphery of the retina. [1]
Micropsia is a condition affecting human visual perception in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema, macular degeneration, or central serous ...
Macular scarring is formation of the fibrous tissue in place of the normal retinal tissue on the macular area of the retina which provides the sharpest vision in the eyes. It is usually a result of an inflammatory or infectious process. [1] Other etiologies include macular pucker (macular detachment), macular hole, and age-related macular ...
