Current status and progress of torpedo maculopathy / 中华眼底病杂志

ABSTRACT

Torpedo maculopathy is a rare, congenital lesion of RPE, which locates temporal to the macula and along the horizontal raphe. The lesion is torpedo-shaped with its torpedo-like tip pointing towards the fovea. As an incidental finding, it often affects only one eye with no damage to central visual acuity. According to its characteristics on OCT, it is divided into 2 types type Ⅰ , attenuation of outer retinal structures without outer retinal cavitation; type Ⅱ, those with both attenuation of outer retinal structures and outer retinal cavitation. Diseases with pigment changes in the RPE layer similar to torpedo maculopathy include congenital hypertrophy of the RPE, RPE lesions in Gardner syndrome, etc. The main point to distinguish the disease from other diseases is its unique location and shape. Most of the torpedo maculopathy lesions are stable and do not require special treatment, but the disease can be complicated by neurosensory retinal detachment, choroidal neovascularization and so on, and symptomatic treatment is needed if necessary.
