Purpose: to compare the results of macular mapping using both OCT 3 softwares: macular map and fast macular map, in the same subjects . Methods: fourteen diabetic patients having diabetic macular edema were followed over a period of 3 months, with clinical examination every two weeks. Measurement of best corrected visual acuity using ETDRS chart, macular thickness measurement using OCT 3 were performed at each visit. OCT 3 mapping was performed using both regular macular map and fast macular map at each visit. Results: all OCT data – 9 OCT3 exams in average per patient , presenting macular map and fast macular map done at the same time, were evaluated. No significant difference in macular thickness was observed between OCT3 regular macular map and fast macular map.The mean difference of macular thickness in the central area 1000 microns in diameter was 4 microns in favor of conventional retinal map. The lowest score was 186 microns with conventional retinal map in the central area and 192 microns with fast macular map in the same area. The maximum score with conventional macular map was 768 microns vs 794 microns with fast macular map. Conclusions: there was no significant difference of retinal mapping either done by OCT3 conventional map program or by fast macular program. The second one is less time consuming and less dependent from fixation patterns.
