AIM : To evaluate the influence of macular laser photocoagulation on contrast sensitivity (CS) function in patients with CSME.
METHOD : A prospective observational study was performed on 50 patients with CSME and no prior history of photocoagulation. Baseline BCVA, CS by Pelli-Robson chart, slit lamp biomicroscopy and flourescein angiography were obtained. Macular laser was performed using Double Frequency Nd:YAG laser and parameters were reassessed after 3 months.
RESULT : CSME resolved in 65%. Visual acuity was stable in 56%, decreased in 35% and increased in 9%. Mean baseline CS was 0.504±0.320 and mean final CS was 0.715±0.377. The CS improved in 68% which was statistically significant, decreased in 6% and remained constant in 26%.
CONCLUSION : Laser photocoagulation in CSME in diabetes helps in improving contrast sensitivity and stabilizes visual acuity. Thus contrast sensitivity can be a useful tool in evaluation of functional vision following laser photocoagulation.
