Purpose:
|
To evaluate the effect of macular photocoagulation (MPC) on peripapillary nerve fiber layer (PNFL) thickness measurement in patients with clinically significant diabetic macular edema (CSME).
|
|
Methods:
|
This study was a prospective interventional case series. Patients with CSME underwent MPC. Optical coherence tomography (OCT) was used to measure the PNFL and central macular thicknesses before and 3 months after MPC.
|
|
Results:
|
Thirty-three eyes of 25 patients with a mean age of 59.4±7.2 years were included. There was no statistically significant difference between pre- and post-MPC mean best corrected visual acuity (0.35±0.29 and 0.40±0.23 LogMAR, respectively, P=0.2). Mean baseline and 3 months central macular subfield thickness was 305.9 ± 90.7 and 317.5± 112.4 microns, respectively (P=0.1). Peripapillary nerve fiber layer thickness was105.7±10.0 before and 106.1±9.9 three months after MPC (P=0.7). No significant differences were found between pre and post MPC measurements in temporal, nasal, inferior and superior nerve fiber layer thickness in each quadrant around optic nerve head (P>0.05).

|
Conclusion:
|
Macular photocoagulation has a negligible effect on PNFL thickness measurements in patients with CSME.
