Structural Pathology after Retinal Detachment Repair on MultiColor Imaging

Abstract Purpose To detect and describe features of structural retinal pathology after successful macula‐off reghmatogenous retinal detachment (RRD) repair using MultiColor (MC) scanning laser ophthalmoscopy. Methods A prospective study of 30 eyes after recent RRD repair. MC images were evaluated for the presence of RRD related pathology. Detection rates were calculated using swept‐source optical coherence tomography (SS‐OCT) as comparative reference. Results The following RRD related lesions were identified: Retinal striae, intraretinal cysts, retinal detachment line, ellipsoid zone disruption (EZD), foveal ellipsoid zone rosette (FEZR), outer retinal fold (ORF), subretinal fluid layer and subretinal fluid blebs. Features of pathology were similar in appearance on MC as compared to enface OCT. Detection rates provided with 95% CI were as follows: retinal striae: 1.00 (0.59–1.0), intraretinal cysts: 0.60 (0.15–0.95), retinal detachment line: 0.84 (0.60–0.97), EZD 0.75 (0.59–0.92), FEZD: 0.73 (0.39–0.94), ORF: 0.86 (0.30‐0.93), subretinal fluid layer: 0.50 (0.12–0.88) and subretinal fluid blebs: 0.70 (0.35–0.93). Conclusion MC imaging is sensitive to detect changes in inner and outer retinal architecture after recent retinal detachment repair, and may become a valuable supplement to OCT in yielding information on the photoreceptor integrity following reattachment surgery. The formation of FEZR is not described earlier.
