Detailed history was taken from every patient after which complete ocular examination including recording of visual acuity, checking pupillary reactions and fundoscopy with special attention to optic nerve head appearance and recording of color vision and light brightness sensitivity was carried out. Specific ophthalmic and systemic investigations were performed. Results: Seven (15.91%) patients had NAION, 6 (13.64%) had demyelinating optic neuritis, 2 (4.54%) had toxic optic neuropathies, 2(4.54%) had nutritional optic neuropathy, 3 (6.82%) had pituitary macroadenoma and 3 (6.82%) had benign intracranial hypertension, 2 (4.54%) had arteritic anterior ischemic optic neuropathy, 2 (4.54%) Pseudo-Foster Kennedy syndrome, 1 (2.27%) had paraneoplastic syndrome, 1 (2.27%) had superior saggital sinus thrombosis, 1 (2.27%) had occipital lobe infarct, 1 (2.27%) had brain metastasis, 1 (2.27%) had craniopharyngioma, 1 (2.27%) had bilateral thalamic ischemia and1 (2.27%) had hydrocephalus.
