Optic Nerve Hypoplasia – Case Report
Original language description
The case report of a young myope (born in 1997) who was diagnosed with bilateral concentric narrowing of the visual field to 15– 20 degrees in 2021 is presented. On eye fundus, the findings were normal with central excavation c/d=0.5 and 0.4, respectively. OCT showed loss of retinal nerve fiber layer – in both vertical quadrants, including a reduction in the ganglion cell complex. Electrophysiological examination (PERG) showed normal retinal responses. Visual evoked responses (PVEP) after stimulation squared a 1 degree decrease in amplitudes, with no prolongation of P100 latency. When stimulated with 15-minute squares, responses were normal (see Supplementary Figure). Magnetic resonance imaging of the brain showed a narrowing of the chiasm. In conclusion, optic chiasm hypoplasia may not always have distinct morphological and functional manifestations. In addition to imaging methods, electrophysiological examination of the visual analyser was of great help for its verification.
