Ekici E, Moghimi S, Hou H, et al. - Researchers conducted this cross-sectional study to examine the central visual field (VF) defects among four phenotypes of glaucomatous optic discs. Optic disc phenotypes were determined in eyes with definite or suspected glaucoma having a 24-2 VF with mean deviation (MD) better than -12 dB and a 10-2 VF. Four hundred forty-eight eyes of 309 patients were identified with four glaucomatous optic disc phenotypes: focal ischemic (FI) (n = 121), generalized cup enlargement (GE) (n = 109), myopic glaucoma (MY) (n = 66), and senile sclerotic (SS) ( n = 152). The severity and prevalence of central visual field loss differ among different glaucomatous optic disc phenotypes. Glaucomatous eyes with FI and MY optic disc phenotypes are more likely to have 10-2 VF loss, especially in early disease, and may benefit from testing with both 10-2 and 24-2 VF tests in particular.
