Full Text PDF


Aim: To make a comparative evaluation of macular thickness in myopia and hypermetropia versus emmetropia.
Materials and Methods: A cross-sectional OCT based study was done in randomly selected 100 emmetropes, 93 myopes, 67 hypermetropes aged between 18 to 30 years regardless of sex.
Results: Average outer macular thickness in emmetropia, myopia and hypermetropia is 276.63±12.5, 275.43±12.1, 286.56±11.4 respectively. Average inner macular thickness was 316.45±11.5, 308.83±11.3, 310.70±12.1 respectively and average central subfield thickness was 243.80±11.2, 248.51±22.9, 240.05±21.9 respectively.
Conclusion: Overall macular thickness in various quadrants was uniform in emmetropia. As compared to emmetropia in myopia average outer and inner subfield macular thickness is lower while average central thickness is higher. In hypermetropia average inner macular and central subfield thickness is lower while outer macular thickness is higher (p=0.001).
