Influence of submacular fluid on recovery of retinal function and structure after successful rhegmatogenous retinal reattachment

Abstract

Purpose To determine the influence of residual submacular fluid (SMF) on the recovery of function and structure of the retina after successful rhegmatogenous retinal detachment (RRD) reattachment. Methods We reviewed the medical records of all patients who had undergone successful RRD repair by scleral buckling (SB) surgery or by pars plana vitrectomy (PPV) from March 2011 to August 2014. Spectral-domain optical coherence tomographic images of the macular regions were used at 1, 2, 3, 6, 9, and 12 months following the surgery. The best-corrected visual acuities (BCVA) were evaluated at the same times. Results The eyes with a macula-off RRD that were treated by SB surgery had a significant higher incidence of residual SMF (52%) than those treated by PPV (6.8%; P <0.001). Nevertheless, the postoperative BCVA was significantly improved in the eyes that had undergone SB surgery ( P = 0.007). The postoperative BCVAs were not significantly different between the groups in which the SMF was absorbed (12 eyes) and not absorbed (13 eyes) within 1 month after the SB surgery. The photoreceptor outer segment length and the presence of a foveal bulge were not significantly different between these two groups at 12 months. Multiple regression analyses showed that the presence of a foveal bulge ( β = 0.531, P = 0.001) and the duration of the retinal detachment before surgery ( β = 0.465, P = 0.002) but not the duration of the SMF were independent factors significantly correlated with the final BCVA. Conclusions These results suggest that the postoperative residual SMF does not significantly disrupt the functional and structural recovery of eyes with macula-off RRD treated by SB surgery.

Postoperative choroidal vascularity index after the management of macula-off rhegmatogenous retinal detachment

“…In our study, comparing 64 eyes that underwent PPV alone and 51 eyes that underwent SB combined with PPV, both groups showed substantial visual improvement after surgery. The final postoperative visual acuity was comparable to that in previous studies on surgery in cases with macula-off RRD [ 29 , 30 ]. We did not observe any significant difference in the final visual outcome between the two surgical groups, which is consistent with a recent study by Ong et al [ 28 ].…”

Does choroidal thickness predict persistent subretinal fluid after rhegmatogenous retinal detachment repair? A retrospective study with fellow eye comparison

“…Our results from multivariate analysis showed that factors associated with pSRF after RRD surgery were SB surgical technique (p < 0.001), macular involvement (p < 0.001) and, in the macula-off SB eyes, detachment duration (p < 0.05). The association between SB surgery and pSRF is in line with previous publications (Baudin et al, 2021;Benson et al, 2007;Chantarasorn et al, 2019;Huang et al, 2013;Kobayashi et al, 2019). Incomplete intraoperative SRF drainage during the SB procedure has been proposed as a possible explanation; however, in our series, we did not find any differences in pSRF incidence between SB eyes that underwent external drainage and those who did not.…”

Restoration of Foveal Bulge after Resolution of Diabetic Macular Edema with Coexisting Serous Retinal Detachment

“…These findings suggest that an intact Previous studies have shown that an intact EZ is associated with better visual recovery after RRD surgery [21][22][23]. However, visual acuity may be still unsatisfactory in some eyes despite an intact EZ after retinal reattachment [8,24]. Hasegawa et al proposed that the presence of a FB at the fovea was associated with better visual acuity after successful RRD repair.…”
