Ganglion Cell-inner Plexiform Layer Thickness and Visual Improvement After Vitrectomy for Rhegmatogenous Retinal Detachment by Jong Young Lee, Eun Kyoung Lee, Dong Yoon Kim, Jin Young Kim, South Korea


ABSTRACT

Purpose:

To evaluate the association of postoperative macular ganglion cell-inner plexiform layer (GCIPL) thickness with postoperative visual outcomes in patients undergoing vitrectomy for macular–off rhegmatogenous retinal detachment (RRD) using spectral domain optical coherence tomography.

Methods:

Data from 22 eyes with macular-off RRDwho were followed for more 6 months after successful pars plana vitrectomy were analyzed. Macular GCIPL thickness in eyes with RRD was compared with that of the normal contralateral eyes 6 months after surgery. The correlation between the interocular difference in GCIPL thickness and postoperative best corrected visual acuity (BCVA) was evaluated.

Results:

Preoperative and postoperative central macular thickness were 538.09 ± 318.42µm, 230.77 ± 34.69µm. Mean GCIPL thickness was significantly decreased with time after surgery (3 months vs. 6 months, P< 0.01). Mean GCIPL thickness in eyes with RRD 6 months after surgery were 61.04 ± 12.04 µm and in the unaffected contralateral eyes were 73.67 ± 6.73 µm. The interocular difference in macular GCIP thickness was significantly correlated with postoperative BCVA. Among patients with intact photoreceptor layers, a greater decrease in GCIPL thickness was correlated with a worse postoperative BCVA (r=0.629; P =0.02). No significant correlation were identified between interocular macular GCIPL thickness difference and age (r = 0.629; P = 0.85), axial length (r = 0.874; P = 0.43).

Conclusion:

Macular GCIP thickness decreased after vitrectomy to repair for RRD. The decrease in GCIP thickness was significantly correlated with postoperative visual outcomes.
