Background: Neuro-Ophthalmology subspecialty is a newly established Unit at the Eye Department of University of Port Harcourt Teaching Hospital. There are hardly any data on neuro-ophthalmic conditions in our environment, so this study will provide the much needed baseline data for future reference. Aim: This is an initial report to identify the spectrum of optic disc findings and determine their relationship with demographic characteristics (age and gender) of patients seen at the Neuro-ophthalmology Clinic of University of Port Harcourt Teaching Hospital. Methodology: This was a hospital-based cross-sectional study with minimum sample size calculated using the formula for cross-sectional studies.7 Using the 95% level of significance, estimated proportion of 0.5, level of precision of 0.10 and non-response rate of 80%; a sample size of 133 was appropriate for the index study. One hundred and thirty three case notes with complete records were retrieved and data extracted on age, sex, presenting symptoms and signs, visual acuity, fundus findings, investigation results, diagnosis and treatment. Data was analyzed with SPSS version 20 and a p-value of 0.05 considered significant. Results: There were 133 patients with a mean age of 37.50±17.51. There were 70 males and 63 females. Most patients had disc pallor - constituting 51.8%; others were disc edema (3.8%), papilledema (3.8%), hyperemia and perivascular sheathing. Fifty-two patients (39.1%) however had normal discs. Disc pallor (64.4%) and temporal disc pallor (66.7%) were commoner in males; but papilledema was commoner in females (80%). These differences were statistically significant (p=0.048). Conclusion: Optic disc findings in neuro-ophthalmic patients this study shows that disc pallor was associated more with the male gender while papilledema was commoner in females.
