Torpedo Maculopathy
Characteristics
- Single oval shaped lesions
- Located close to the fovea
- usually temporal and unilateral
- leading edge points towards the fovea
- Causes a scotoma
- Not associated with other vision loss
- In isolation not associated with other disease
- Can occur with other pigmented lesions typically seen in Familial Adenomatous Polyposis

Figure 1 from reference [2] Torpedo maculopathy in patient 1. (A) Hypopigmented lesion along the horizontal raphe with a tip towards the centre of the macula and a slightly pigmented tail. (B) Lesion hyperfluorescence on fluorescein angiography, secondary to the window defect. (C) Horizontal optical coherence tomography (OCT) (Stratus OCT; Carl Zeiss Meditec, Dublin, California) image taken of the superior aspect of the lesion revealing a large cleft and a seemingly absent retinal pigment epithelium signal. (D) Humphrey visual field (10-2) testing showing a corresponding scotoma. (E) Fundus autofluorescence shows hypoautofluorescence of the lesion. (F) Same OCT (Stratus OCT; Carl Zeiss Meditec, Dublin, California) cut of the lesion 2 years later showing no change in the cleft. There is increased irregularity in the photoreceptor layer of the retina. (G) Spectralis HRA+OCT (Heidelberg Engineering, Heidelberg, Germany) taken 4 years later showing the large cleft, the abnormal outer retinal layer, and the increased signal transmission in the choroid more clearly. (H) Three-dimensional view of the lesion using Spectralis OCT.
