The baseline optic disc morphology was used to classify the eyes into four types: focal ischemic type (FI), myopic glaucomatous type (MY), senile sclerotic type (SS), and generalized enlargement type (GE). The morphological parameters of the disc were determined by the Heidelberg Retina Tomograph II (HRT-II) and the visual function by the mean deviation (MD) of the Humphrey field analyzer.Results: Fourteen eyes were classified as the FI type; 52 as the MY type; 17 as the SS type; and 20 as the GE type. The highest correlation coefficients of HRT-II parameters to the MDs was the cup/disc area ratio (r&nbsp;= -0.27) for all groups, the vertical cup/disc ratio (r&nbsp;= -0.42) in the MY group, the maximum cup depth (r&nbsp;= 0.49) in the SS group, and the cup area (r&nbsp;= -0.70) in the GE group. However, none of the parameters was correlated in the FI group.Conclusions: The correlation between the HRT-II parameters and MDs was different for the four disc types. These findings suggest that a classification of optic disc morphology had a benefit for interpreting the measured values of HRT-II.Keywords: open angle glaucoma, optic disc morphology, classification, visual function Kazuko OmodakaToru NakazawaTakaaki Otomoet alDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2010, Iss default, Pp 765-772 (2010)
