Homonymous hemianopia and glaucomatous optic disc changes: Rare co-existence
Homonymous hemianopia is a visual field defect involving either two right or the two left halves of the visual field of both eye. It results from the damage of the visual pathway in its suprachiasmatic part. The causes of homonymous heminopia include stroke, brain tumors, head injuries, neurosurgical procedures, multiple sclerosis and miscellaneous conditions. It is challenging task to differentiate whether optic disc changes or visual field defects are secondary to glaucoma or neurological causes. We report a case of 42 yrs old male with chief complaint diminution of vision in left eye for 5 months with optic cup disc ratio of right eye 0.6 and left eye 0.8 with inferior focal notching in left eye, temporal pallor both eyes on fundus examination and left homonymous hemianopia on perimetry. Thus this case presents a rare coexistence of glaucomatous optic disc changes associated with left homonymous hemianopia.
