PURPOSE: To identify the optical coherence tomography biomarkers that can collectively predict the probability of collapse or reduction of drusenoid pigment epithelium detachment (PED).
METHODS: This consecutive observational case series reviewed the clinical data of 24 eyes with non-neovascular drusenoid PED. Among the study population, 17 eyes showed collapse or reduction of drusenoid PED. The mean follow-up duration was 44.8 ± 24.6 months. Optical coherence tomography-derived parameters were analyzed at baseline, at the last available visit before reduction of PED, at the first available visit after reduction of PED, and at the final visit.
RESULTS: The mean subfoveal choroidal thickness showed a significant decrease after PED reduction and at the most recent visit (P = 0.015). Migration of retinal pigment epithelium cells was detected in 15 (88.2%) after PED reduction; however, there was no significance in the frequency of migration of retinal pigment epithelium cells at each time point (P = 0.392). Non-neovascular subretinal fluid was detected in 7 (41.2%) before PED reduction, 2 (11.8%) after PED reduction, and 2 (11.8%) at the final visit. Interestingly, subretinal fluid appeared more frequently just before reduction of PED (P = 0.029).
CONCLUSION: We found evidence of non-neovascular subretinal fluid and choroidal thinning before reduction in PED. This finding might be useful for detection and prediction of the progression of drusenoid PED.
