Abstract Details



Purpose:

To evaluate the postoperative ganglion cell-inner plexiform layer (GC-IPL) and retinal nerve fiber layer (RNFL) thickness changes in eyes undergoing Brilliant Blue G (BBG) assisted epiretinal membrane (ERM) surgery using spectral-domain optical coherence tomography (OCT).

Setting:

Turgut Özal University Medical Faculty Department of Ophthalmology

Methods:

The study included 25 eyes of 25 patients undergoing ERM and ILM peeling using BBG. Quantitative analysis of the GC-IPL and peripapillary RNFL was performed by Cirrus HD-OCT (Carl Zeiss Meditec) preoperatively and for 6 months postoperatively on both eyes.

Results:

The mean preoperative GC-IPL (50.75 ± 24.33 µm) was significantly (p< 0.05) thinner in vitrectomized eyes compared to the fellow eyes (69.81 ± 19.09 µm), whereas the mean preoperative RNFL thickness was not significantly (p> 0.05) different between the study (91.44 ± 12.32 µm) and control eyes (89.20 ± 14.32 µm). The mean postoperative GC-IPL thickness (44.58 ± 18.57 µm) was not significantly different (p> 0.05) compared to the mean preoperative measurement (50.75 ± 24.33 µm) except for the significant reduction in inferotemporal quadrant (P< 0.05). The mean postoperative RNFL thickness (74.45 ± 11.02 µm) was not significantly different (p> 0.05) compared to the mean preoperative measurement (91.44 ± 12.32 µm) except for the significant reduction in temporal quadrant (P< 0.05).

Conclusions:

GC-IPL and RNFL thicknesses showed localized reduction after ERM surgery with BBG during 6-month follow-up period.
