BACKGROUND/PURPOSE

To investigate the retinal and choroidal vasculature in patients with torpedo maculopathy with optical coherence tomography-angiography (OCT-A).

METHODS

Retrospective case series of four patients who were examined at the department of Ophthalmology at the University Hospital Bern. Main Outcome was the lesion size over time in OCT-A and fundus autofluorescence.

RESULTS

Three patients had Type I and 1 patient had Type II torpedo maculopathy. Torpedo maculopathy lesion size remained stable in all patients over a mean period of observation of three years in OCT-A and fundus autofluorescence. The choriocapillaris network was attenuated focally within the lesion in OCT-A in all four cases. The lesion size in fundus autofluorescence was 2.77 mm and therefore comparable with the lesion size in OCT-A of 2.75 mm.

CONCLUSION

OCT-A signal of the choriocapillaris was reduced within the cleft in both types of torpedo maculopathy. Whether the changes represent the primary site of malformation or whether these findings are the consequence of a defect in the retinal pigment epithelium remains speculative.
