Abstract
PURPOSE: To identify the peripapillary retinal nerve fiber layer, total macular, ganglion cell layer, and inner plexiform layer thicknesses in children with high hyperopia using spectral domain optical coherence tomography. METHODS: Twenty-one children with high hyperopia and 20 controls were enrolled in this study. Subjects with spherical equivalent +5.0 D or higher were evaluated in the study group and subject with spherical equivalent between +0.25 and +2.0 D in the control group. The retinal nerve fiber layer thickness, macular thickness, macular ganglion cell layer and inner plexiform layer thicknesses were measured using a spectral domain optical coherence tomography, and results were compared between groups. RESULTS: The nasal and inferior quadrant and the global retinal nerve fiber layer thickness were significantly thicker in the study group. The mean thickness of inferior quadrant of the inner macula was significantly thicker in the study group than those in the control group. The mean thickness of the ganglion cell layer in nasal, temporal and inferior quadrant of outer macula was significantly thinner in the study group than the control group. The mean thickness of the inner plexiform layer in the inferior quadrant of the inner macula and nasal and inferior quadrant of the outer macula were significantly higher in study group than those in control group. CONCLUSION: High hyperopic children had thicker retinal nerve fiber layer when compared to the controls. This difference should be taken into account when evaluating children with glaucoma or other optic disc disorders.
