Aim: To investigate the variation in average retinal thickness in macular region in otherwise normal young myopic subjects by using optical coherence tomography (OCT). Methods: One hundred and thirty ophthalmologically normal men 20 to 24 years of age with myopia (spherical equivalent, 0.25 to 14.25 D) underwent examination of one randomly selected eye. Tests performed were Visual acuity, BCVA with refraction, slit lamp examination, IOP by applanation tonometry, gonioscopy, Ascan ultrasound, fundus examination, visual field testing by HFA, and optic disc photography. Exclusion criteria were visual acuity better than 6/9, previous intraocular surgery, intraocular pressure >21 mm Hg or other ocular diseases. Three horizontal transfixation and three vertical transfixation OCT scans of 6 mm each were conducted on each eye by a single investigator. Neurosensory retinal thicknesses was measured, and the overall average, maximum, and minimum retinal thicknesses were analyzed. Results: The average retinal thickness of the macula does not vary with myopia. However, the parafovea was thinner and the fovea thicker with myopia.
