Abstract
PURPOSE
To evaluate macular microvascular changes and their correlation with visual outcomes after rhegmatogenous retinal detachment (RRD) surgery.
DESIGN
Retrospective case series PARTICIPANTS: Seventy-four eyes successfully operated for RRD were included in the study.
METHODS
The area of the foveal avascular zone in the superficial capillary plexus, the vessel density in the superficial capillary plexus (SCP), deep capillary plexus (DCP), and choriocapillary plexus (CCP) were evaluated using optical coherence tomography angiography (OCTA) at 1 and 6 months postoperatively. The fellow eyes were used as controls for comparison.
MAIN OUTCOME MEASURES
The correlation between OCTA parameters and postoperative best-corrected visual acuity (BCVA) was assessed using a hybrid linear mixed model. We also analyzed the relationship between OCTA parameters and the integrity of the external limiting membrane (ELM) and ellipsoid zone (EZ) of photoreceptors.
RESULTS
The median vessel density in the DCP was significantly decreased in RRD eyes at 1 month (p=0.019), but gradually improved over time to reach the value of the fellow eyes at 6 months (p=1). There was no significant difference between the 2 groups in median foveal avascular zone area, vessel density in the SCP and in the CCP (p=0.579, p=0.618, p=0.068 and p=0.819, p=1 and p=1, respectively) at both 1 and 6 months postoperatively. Postoperative BCVA was positively correlated with the vessel density in the DCP (p=0.009) in multivariate analysis. Eyes with low 1-month vessel density in the DCP tended to have worse final BCVA (p=0.067). There was no correlation between the vessel density in the DCP and ELM and/or EZ integrity at both 1 (p=0.156) and 6 months postoperatively (p=0.161). Eyes with intact ELM and EZ at 6 months, however, had significantly higher 1-month vessel density in the DCP than those with disrupted ELM and/or EZ (p=0.027).
CONCLUSION
The vessel density in the DCP was affected in RRD eyes as well as associated with postoperative BCVA and the restoration of photoreceptor layers. It might thus serve as a predictor for visual recovery following successful RRD surgery.
