Background: The need to establish the normal parameters of the macular is important for early detection of macular changes in diabetic patients, individuals at risk of age-related macular degeneration and other causes of maculopathy. Objectives: To determine the normative values for macular thickness in healthy Nigerian adults in Ahmadu Bello University Teaching Hospital, Zaria and to correlate macular thickness values with gender, age, axial length, refractive errors, parity and intraocular pressure in adults using Stratus Optical Coherence Tomography. Subjects and Methods: Consenting 178 (101 males and 77 females) adult Nigerians with normal eyes were recruited and examined using Carl Zeiss Stratus Optical Coherence Tomography ( OCT ) machine Model 3000 software version 4.0. Data was analyzed using the independent sample t-test, one- way ANOVA and Sheffe post- hoc. Pearson method was used for correlation analysis. Results: One hundred and seventy-eight (178) eyes of 178 subjects were assessed. Mean age of subjects was 36.4 ± 11.7 years. Mean Total Macular Thickness (MTMT), was found to be 238.03 ± 16.83μm with an average of 240.45 ± 17.34μm in males and 234.84 ± 15.70μm in females. MTMT was also found to be 283.84 ± 16.12μm, 283.85 ± 16.37μm and 283.64 ± 17.59μm in Hausa (n = 106), Igbo (n = 03) and Yoruba’s (n = 20) respectively. Mean Central Foveal Thickness (MCFT) was 180.30 ± 19.22μm with an average of 185.73 ± 18.06μm in males and 173.18 ± 18.46μm in females. Conclusion: Total macular thickness and central foveal thickness measurements in healthy Nigerian adult eyes in Zaria are presented in this study and results are comparable to that reported in previous studies. However, large population study is required in Nigeria’s six geopolitical zones in order to derive a reference value for the country.
