    Thick Macula + good refraction possibility?
    onecat posted:
    yet another question please:

    does the 'thickness' of the macula determine the degree of refraction-success ? i.e. if thickness exists (OCT 297) could that mean a reading of 20/40 on the Snellen chart is the best correction available?
    Would a cataract 'cause' thickening of the macula ?
    Sorry for being confusing but so appreciate your reading this !

    Alan M Kozarsky, MD responded:
    The macula is the center part of the retina which is responsible for high resolution vision. There are conditions which can make the macula swell and measure thicker on an OCT image scan. If the macula is swollen, vision will be decreased, even with the best possible pair of glasses.

    Cataracts do not cause thickening of the macula but occasionally, the macula can swell AFTER cataract surgery.
    onecat replied to Alan M Kozarsky, MD's response:
    this sheds much light on the situation due to a 'swollen' macula then !
    operated eye could still be 'healing' (now 3.5 months post-op) ; remaining eye also has 297 OCT (currently same for operated eye). So i'm assuming you feel the unoperated eye could end up in same condition as operated eye. i.e. results may not be able to be corrected below 20/40 due to many reasons for 'high' OCT measurements that even cataract removal won't remedy . Thank you so very much for explaining this !!!!
