To evaluate the long term serial follow up of patients with scarred choroidal neovascular membrane by imaging, using microperimeter (MAIATM), in order to quantify the area covered by the scarred choroidal neovascular membrane and to determine changes in the area of the scar and bivariate contour ellipse area over a period of time.
8 eyes of 7 patients meeting the inclusion and exclusion criteria were enrolled for the study and followed up for 6 visits at 6 weekly intervals. All patients underwent vision assessment and microperimetry (MAIATM ) at each visit. Serial images were analyzed using custom software for calculating the area of the scar and the changes over the period of time.
The analysis revealed average initial scarred choroidal neovascular membrane area to be 92 degrees2 and showed statistically no change over the course of follow up. Similarly, the initial bivariate contour ellipse area (BCEA) was found to be 61degrees2 with no change over time. The structural functional correlation between the scar and the BCEA was studied, and there was no significant correlation between the two.
Microperimeter can be used as an assessment tool for serial changes over time in patients with scarred choroidal neovascular membrane.
