Abstract

Purpose: To evaluate the changes in the optic nerve head in highly myopic subjects by means of confocal laser scanning opthalmoscope. Methods: Using laser scanning and a three-dimensional image analysis system, we studied 114 young (21.4 +/- 1.4 years), highly myopic subjects with refractive errors greater than -8.0 D and a control group of 29 subjects (18.9 +/- 1.2 years) with myopia of -3.0 D or less, Measurements included cycloplegic refraction, corneal curvature, biometric axial length, and morphometric values of the optic disc obtained with a laser scanning disc analyzer. Results: The optic disc area in highly myopic eyes was similar to that in mildly myopic eyes. However, regression analysis revealed that the optic disc area increased with axial length in subjects with severe myopia. The cup/disc ratio, the disc depth, the neuroretinal rim area, and the Lilting of the disc were not significantly different between the severe and mild myopia groups. Conclusions: These findings may be useful in further investigations of myopic progression and of the mechanisms responsible far the development of:myopic complications.
