Abstract
Purpose To observe the changes in metamorphopsia after scleral buckling (SB) surgery for macula-off rhegmatogenous retinal detachment (RRD) and its association with morphological changes in the macula. Methods This prospective study included 20 eyes of 20 patients. Before surgery and 1, 3, 6, and 12 months after surgery, metamorphopsia measured by M-charts and best-corrected visual acuity (BCVA) and macular microstructures assessed using optical coherence tomography were recorded. Results Both the vertical and horizontal M-scores improved significantly after SB surgery. BCVA also improved gradually. The mean M-score in the eyes with a continuous external limiting membrane (ELM) was smaller than that in the eyes with a disrupted ELM (P=0.008). Preoperative and postoperative BCVA did not correlate with the mean M-score at any time point. The other studied parameters, namely, the duration of RRD, the height of retinal detachment, central foveal thickness, inner nuclear layer thickness, and continuation of the ellipsoid zone, were also not relevant. Conclusions The continuation of the ELM may be a critical factor in determining the severity of metamorphopsia after SB surgery for macula-off RRD.
Highlights
As the most frequent form of retinal detachment, rhegmatogenous retinal detachment (RRD) is an emergency among retinal diseases [1]
Metamorphopsia is a prevalent and persistent symptom identified by patients, especially those with maculaoff RRD [6, 7]. e reported incidence of metamorphopsia ranges from 39% to 88%, and it greatly impairs patients’ quality of vision [8,9,10]
It has been adopted in studies on metamorphopsia involving the epiretinal membrane (ERM), macular holes, and branch retinal vein occlusion (BRVO) [15,16,17]
Summary
As the most frequent form of retinal detachment, rhegmatogenous retinal detachment (RRD) is an emergency among retinal diseases [1]. First introduced in 1999, M-charts serve as a handy tool to assess metamorphopsia both quantitatively and sensitively [14]. It has been adopted in studies on metamorphopsia involving the epiretinal membrane (ERM), macular holes, and branch retinal vein occlusion (BRVO) [15,16,17]. Scleral buckling (SB) surgery, which is an effective method for treating RRD, disrupts the homeostasis of the intraocular environment relatively less [20] It offers an ideal model for studying the factors that influence metamorphopsia after retinal detachment. It offers an ideal model for studying the factors that influence metamorphopsia after retinal detachment. e purpose of this study was to observe the changes in metamorphopsia after SB for macula-off RRD and its association with morphological changes in the macula
