Abstract
- Purpose: To study the frequencies and factors associated with 4 disc patterns in primary open-angle glaucoma (POAG) identified in population-based studies: focal glaucomatous (FG type), generalized enlargement of cup (GE type), myopic glaucomatous (MG type), and senile sclerotic glaucomatous (SS type) patterns.<br />Subjects: In total, 270 disc photographs of acceptable quality were extracted from the records of 270 definitive POAG cases diagnosed according to the International Society of Geographical and Epidemiological Ophthalmology Criteria in 2 Japanese population-based glaucoma surveys. One randomly chosen eye from the bilateral POAG cases was included.<br />Results: Using a method of κ coefficient of reproducibility of classification of 0.80 according to a preliminary study, 143 discs were classified as FG, GE, MG, or SS types with respective frequencies of 57% (95% confidence interval [CI], 48-66), 33% (95% CI, 25-42), 7% (95% CI, 3-13), and 3% (95% CI, 0-7), and 127 discs as the miscellaneous type. Multinomial logistic regression analysis showed that the MG type was associated (P=0.052, 0.025, 0.019, and 0.018) with younger age, lower body mass index (BMI), and greater disc area and ovality, and the GE type was associated (P<0.001, 0.036, and 0.056) with greater disc area, corneal radius, and hyperopic refraction than the FG type.<br />Conclusions: The FG type occurs most frequently in Japanese POAG followed by the GE type. The MG and SS types occurred much less often than previously reported in Japanese. Associations with age, BMI, disc area and ovality, refraction, and corneal radius differed among the FG, GE, and MG types.
