Clinical characteristics of cuticular drusen in the Japanese population

To investigate the clinical characteristics of eyes with cuticular drusen in Japanese individuals, while paying special attention to large colloid drusen (LCD).
Retrospective case series.
Eyes with cuticular drusen, from patients of 4 medical institutes in Japan, were investigated. Multimodal imaging findings were used to diagnose cuticular drusen. LCD was defined as cuticular drusen > 200 µm.
Twenty-four eyes from 12 patients (8 women, 4 men) were diagnosed with cuticular drusen. The mean age of all patients (n = 12) was 60.8 years. The mean age of patients without additional macular pathology (n = 5) was 55.4 years. Of the 7 patients with additional macular pathology, 6 (85.7%) exhibited age-related macular degeneration-associated macular pathology, including drusenoid pigment epithelial detachment (PED) (8 eyes from 4 patients), geographic atrophy (2 eyes from 1 patient), and occult choroidal neovascularization (1 eye). LCD were found in 6 eyes of 3 patients (25%), those with LCD were on average 53.7 ± 8.7 years old and those without 69.9 ± 14.1 years of age (P = 0.064, Mann–Whitney U test).
Cuticular drusen were predominantly seen in females, and drusenoid PED was most frequently seen in eyes with additional macular pathology. LCD were seen in 25% of eyes with cuticular drusen.
