Purpose:
To report a case of polypoidal choroidal vasculopathy associated with sector retinitis pigmentosa.
Methods:
Case report.
Results:
A 63-years-old woman presented with complaints of having painless progressive reduction of vision in the left eye (LE) for the past 6 months. On examination, her best-corrected visual acuity was 20/20 in the right eye and 20/125 in the LE. Based on fundus examination and multimodal imaging findings, both eyes were diagnosed to have sector retinitis pigmentosa, and an associated active extramacular polypoidal choroidal vasculopathy was seen in the LE. Spectral-domain optical coherence tomography also revealed choroidal thinning in both eyes. Patient underwent bevacizumab injection in the LE. At 1-month posttreatment, her best-corrected visual acuity remained stable in the LE, and spectral-domain optical coherence tomography showed reduction in subretinal fluid and size of the polypoidal lesion.
Conclusion:
Polypoidal choroidal vasculopathy, a pachychoroid disease, could occur in association with retinitis pigmentosa, in the setting of thin choroids, and multimodal imaging is important to differentiate it from Type-1 macular neovascularization.
