Methods According to the involved area in the fundus, the distribution of RPD was classified as localised, intermediate, or diffuse type. Morphology of RPD was classified as discrete, branching, or confluent pattern. The presence of late AMD was evaluated. Results 233 eyes of 121 patients with RPD were included. The distribution of RPD was localised, intermediate and diffuse type in 30.9%, 40.3% and 28.8% of eyes, respectively. The discrete, branching and confluent morphological patterns were found in 45.8%, 44.8% and 9.7% of the localised type, and in 0%, 13.8% and 86.2% of the intermediate type, respectively. In contrast, the diffuse type showed only the confluent morphological pattern. The prevalence of accompanying late AMD was 13.9%, 13.8% and 56.7% in the localised, intermediate and diffuse type, respectively, and it was significantly higher in the diffuse type (p<0.05). Conclusion RPD with diffuse distribution showed a confluent morphological pattern and a high prevalence of late AMD. RPD can be classified by the fundus distribution for the assessment of visual prognosis.
