Abstract

Background Patients with exudative maculopathies (neovascular age-related macular degeneration (nAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO)) are faced with a high burden of examinations and treatments. This study was conceived to analyze the accuracy of a subjective evaluation of visual acuity (VA) and metamorphopsia to detect disease reactivation, compared to morphological signs of reactivation assessed by means of SD-OCT. Methods Retrospective study of 888 patients treated for nAMD (n = 638), DME (84), BRVO (110), and CRVO (56) was conducted. Subjective evaluation of the patient at an examination (i.e., change of VA and/or metamorphopsia) was compared to clinical evaluation of disease activity as assessed by SD-OCT. Sensitivity and specificity, negative and positive predictive values (PPV/NPV) for detection of active disease were calculated. Factors associated with false-negative subjective evaluation were analyzed by regression analysis. Results The sensitivity of the subjective evaluation to detect disease reactivation was < 0.50 in all exudative maculopathies. Sensitivity was increased to ≥ 0.60 by combining subjective worsening with loss of 1 line in the VA test in RVO, but not in DME and nAMD. The specificity was > 0.85 in all patients.
