STRUCTURAL PATHOLOGY AFTER RETINAL DETACHMENT: Multicolor Confocal Scanning Laser Ophthalmoscopy Versus Color Fundus Photography.

Abstract

To compare pathology detection using multicolor confocal scanning laser ophthalmoscopy with color fundus photography following macula-off rhegmatogenous retinal detachment. Postsurgery multicolor confocal scanning laser ophthalmoscopy and color fundus photography images from 30 rhegmatogenous retinal detachment patients were examined by 10 masked graders. Imaging was performed with the Heidelberg Spectralis HRA and the digital retinal camera Basler acA2500-14gc GigE. Swept-source optical coherence tomography was used as verification modality. Detection rates of ellipsoid zone disruption, foveal ellipsoid zone rosette, outer retinal folds, intraretinal cysts, subretinal fluid layer, subretinal fluid blebs, retinal striae, and retinal detachment line were compared. Intermodality and intergrader agreement were estimated. Overall pathology detection was significantly higher for multicolor confocal scanning laser ophthalmoscopy multicolor confocal scanning laser ophthalmoscopy (adjusted odds ratio = 7.39; 95% confidence interval, 1.64-33.30; P = 0.009). The intermodality and intergrader agreement on overall pathology detection were moderate. The intermodality agreement was 0.49 (95% confidence interval, 0.48-0.51; P < 0.0001) (Gwet's AC1). Intergrader agreement was 0.53 (95% confidence interval, 0.52-0.54; P < 0.0001) for multicolor confocal scanning laser ophthalmoscopy and 0.58 (95% confidence interval, 0.57-0.59; P < 0.0001) (Fleiss kappa) for color fundus photography. Multicolor confocal scanning laser ophthalmoscopy imaging is superior to color fundus photography in detecting and delineating structural retinal abnormalities following rhegmatogenous retinal detachment and can be a helpful tool in the visualization of retinal remodeling processes in patients recovering from rhegmatogenous retinal detachment surgery.
