The Influences of High Refractive Error on Macular Thickness, Ganglion Cells Layers and Retinal Detachment Incidence
Journal Title: Ophthalmology and Vision Science - Year 2017, Vol 1, Issue 4
Abstract
Objective: To investigate the influence of high refractive errors on the incidence of retinal detachment. Design: A cross sectional study. Material and Methods: One Hundred subjects were recruited in this study. A total of 191 eyes were examined. Vision was tested using Snellen ‘s test type (E-test), refraction was done objectively by Streak Retinoscope (Heine Beta 200), the axial length was measured with A/B Scan index US 400 Jap ultrasound and the optical coherence tomography (OCT) was used to measure the macula and ganglion cells thickness and to detect the presence of retinal detachment. Results: Myopia was the most common refractive errors in this study. 183 myopic eyes ( 95.81%) and 8 hypermetropic eyes (4.19%) were diagnosed in this study. The results showed that the maximum degree of myopic subjects were located between 5 to 6 diopters (42.08%), while the lowest degree were registered between 13 to 24 diopters (3.82%). The mean age and standard deviation (SD) for myopic degree were -8.22 (5.04), while hypermetropic degree had 4.32 (1.49). Conclusions: High refractive errors for instance myopia decrease the thickness of macula and ganglion cells.
