To investigate changes in the severity of aniseikonia after macula-off rhegmatogenous retinal detachment (RD) surgery, and to evaluate the relationship between aniseikonia and retinal microstructures assessed with optical coherence tomography (OCT) as well as characteristics of RD.
The study included 26 eyes of 26 patients undergoing retinal detachment surgery. Visual acuity was measured preoperatively, and at 3, 6, and 12 months postoperatively. Degree of aniseikonia (quantified using the New Aniseikonia Test) and OCT images were obtained at 3, 6, and 12 months postoperatively.
The aniseikonia values (mean ± standard deviation) at 3, 6, and 12 months postoperatively were -5.3 ± 4.2%, -4.4 ± 4.4%, and -3.1 ± 3.2%, respectively. Significant improvement was observed from 3 to 12 months postoperatively (P = 0.001). Twelve months postoperatively, 14 eyes (54%) had micropsia, 1 eye (4%) had macropsia, and 11 eyes (42%) were free of aniseikonia. Stepwise multiple regression analyses revealed that the severity of aniseikonia at 12 months postoperatively was significantly associated with postoperative development of cystoid macular edema (CME) (r = -4.67, F = 21.99) and epiretinal membrane (ERM) (r = 2.38, F = 7.12), as well as area of preoperative RD (r = -0.033, F = 20.00).
After successful retinal detachment surgery, aniseikonia gradually improved, but nearly half of patients still exhibited aniseikonia at 12 months postoperatively, and almost all of them had micropsia. Presence of postoperative CME, ERM, and area of preoperative RD were related to the severity of aniseikonia.
