Abstract
AIM: To compare the Corneal thickness and Corneal Epithelial Thickness distribution in Myopic south tamilnadu eyes using Spectral Domain Optical Coherence Tomography. METcorneaObservational study measured total corneal and epithelial thickness in the central 2 mm zone and eight sectors each in paracentral 2-5 mm (ring 1) and midperipheral 5-6 mm (ring 2) zones on SD-OCT among age group 10 to 40 yrs and MRSE ranging from -0.50D to – 12.00 D. RESULTS: Study included 150 eyes of 150 subjects with male: female ratio of 80:70.The thickest and thinnest part of epithelium were found at the nasal-inferior sector and at the superior side respectively. Subjects in the low and moderate myopia groups have thicker epithelial thickness than those in the high myopia group. CONCLUSIONS: The epithelial thickness is not evenly distributed across the cornea. Epithelium was thickest in nasal-inferior sector. People with high myopia tend to have thinner corneal epithelium than low-moderate myopic patients.
