Fundus fluorescein angiography examination was also performed. The visual acuities were 20/25, 20/25, and 20/15.</p><p><strong>Results: </strong>Optical coherence tomography showed defects of the optic nerve fiber at the pit area in all 3 eyes. No neurosensory epithelium detachment was found. The first female patient had a window defect in both eyes. One eye of the second female patient had epiretinal membrane and macular edema. Visual field test showed a paracentral scotoma in the first female patient and peripheral constric- tion in the second female patient. Fundus fluorescein angiography showed late hyperfluorescence at the pit.</p><p><strong>Conclusion: </strong>Optical coherence tomography may be helpful in the management of optic nerve head pit in searching for neurosensory epithelium detachment and macular edema.</p>}, number={1}, journal={Hong Kong Journal of Ophthalmology}, author={Li, Yong and Dai, Hong and Long, Li and Cui, Bao-hua}, year={2004}, month={Dec.}, pages={20–22} }
