Abstract
A 32-year-old healthy woman with a history of poor visual acuity of the left eye was found to have a temporal optic nerve head pit, with no leakage on fluorescein angiography. Visual field showed a caecocentral scotoma, more profound at the location related to the pit. Optical coherence tomography showed the characteristics of the optic pit and excluded signs of previous macular detachment; Moreover, it disclosed a significantly reduced retinal nerve fiber layer thickness at the papillomacular bundle. Thus, reduction of the papillomacular bundle is an additional cause of poor visual acuity in cases of optic pit.
