Abstract
Myopia is the commonest refractive error encountered in the OPD among young adults. High myopia is
dened as the refractive error more than or equal to -6.0D Spherical equivalent or Axial length more than
or equal to 26.5mm. This study aims to observe the correlation of the macular thickness in patients with high myopia using
Ocular Coherence Tomography. This observational study was conducted for a period of 6 months on 55 subjects. The foveal,
parafoveal and perifoveal thickness were assessed using fast macular thickness scanning protocol. Full foveal thickness was
not correlated with spherical equivalent (p value >0.05) but the parafoveal and perifoveal thicknesses had signicant positive
correlations with SE (p value>0.05). Serial follow up of high myopic patients with OCT helps in assessing the rate of alteration in
macular thickness which helps in helps in understanding the macular thickness status while evaluating other macular
pathologies.
