Study Purpose

To assess morphological optic disc dimensions using spectral-domain optical coherence tomography (OCT) in a Nigerian population

Study Design

Retrospective

# of Eyes/
Patients

147 eyes of 88 subjects

Study Device

Topcon 3D OCT-1 Maestro

Outcome Measures

Disc area (DA), vertical disc diameter (VDD), and horizontal disc diameter (HDD)

The mean age of the study subjects was 52.6 ± 20.9 years with a range of 8-90 years; male to female ratio was 1:1.3
The mean DA, VDD, and HDD were 2.54 ± 0.48 mm2, 1926.5 ± 189.6 µm and 1673.9 ± 173.9 µm, respectively
Males had significantly larger DA than females (2.56 ± 0.53 mm2 vs 2.51 ± 0.44 mm2, p = 0.043)
The mean DA and VDD of eyes of subjects aged 21-40 years were significantly higher compared to subjects aged 60 years and older (p = 0.008 and 0.001, respectively)

IMOvifa reduced measurement time by

39%

Conclusions

The mean optic disc area and diameters are larger than those reported in similar studies involving blacks and other races. The mean disc area was found to be larger in subjects aged 21-40 years in comparison to subjects aged 60 and older.
