Morphological features and important parameters of large optic discs for diagnosing glaucoma.

ABSTRACT:

Purpose

To compare the optic disc parameters of glaucomatous eyes to those of non-glaucomatous eyes with large discs.

Methods

We studied 225 consecutive eyes with large optic discs (>2.82 mm2): 91 eyes with glaucoma and 134 eyes without glaucoma. An eye was diagnosed with glaucoma when visual field defects were detected by the Humphrey Field Analyzer. All of the Heidelberg Retina Tomograph II (HRT II) parameters were compared between the non-glaucomatous and glaucomatous eyes. A logistic regression analysis of the HRT II parameters was used to establish a new formula for diagnosing glaucoma, and the sensitivity and specificity of the Moorfields Regression Analysis (MRA) was compared to the findings made by our analyses.

Results

The mean disc area was 3.44±0.50 mm2 in
