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]
Metamorphopsia is a symptom of several common retinal and macular diseases, therefore treating the underlying disorder can improve symptoms. For people who have conditions such as epiretinal membrane (ERM), macular holes and retinal detachment , decreased metamorphopsia is associated with an increase in visual acuity . [ 4 ]
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 ...
Retinal detachment should be considered if there were preceding flashes or floaters, or if there is a new visual field defect in one eye. [2] [3] If treated early enough, retinal tear and detachment can have a good outcome. [2]
Diabetic Macular Edema (DME): is an eye disease specifically related to diabetes, occurring due to fluid build-up in the retina as a result of sustained high blood glucose levels. It can result in blurred vision and vision loss. [5] Eye floaters and spots: where visible cloud-like images appear to "float" in an individual's field of vision. [6]
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 ...
Age-Related Macular Degeneration is a degenerative maculopathy associated with progressive sight loss. It is characterised by changes in pigmentation in the Retinal Pigment Epithelium, the appearance of drusen on the retina of the eye and choroidal neovascularization. AMD has two forms; 'dry' or atrophic/non-exudative AMD, and 'wet' or ...
Treatment for optic pit-associated macular detachment involves photocoagulation of the retina by use of an ion laser (either krypton or argon). This procedure works by burning one or more rows in between the optic disc and areas of serous retinal detachment. In most cases, macular reattachment results and visual acuity can be restored to about ...
