Altered Macular Thickness and Dissociated Optic Nerve Fiber Layer Post Repair

This is an OCT montage of the left eye of a 62-year-old female patient who had repair of macular hole left eye. Note how the temporal macula thins following a successful macular hole repair surgery (red bracket). The yellow arrows highlight the divots that are characteristic of a dissociated optic nerve fiber layer. These small divots are thought to be due to Muller cell trauma caused by internal limiting membrane peeling. Although microperimetry can show small scotomas associated with these divots and there may be a decrease in contrast sensitivity, there seems to be no clinically meaningful effect on visual acuity.
