Pattern Dystrophy
Clinical Features:
There are dark, yellow, and/or orange pigment disturbances at the level of the RPE, leading to characteristic patterns of deposition in the central macula, which are often vitelliform-like (Fig. 12.3.1). There is a lifetime risk up to 18% of developing secondary choroidal neovascularization. The clinical features are usually symmetric, but there can be heterogeneity between eyes (Fig. 12.3.2).
Figure 12.3.1 Color fundus photograph shows a yellowish, circular vitelliform-like lesion within the central macula.
