Subretinal neovascular membrane associated with type 2a idiopathic juxtafoveolar telangiectasis in pseudoxanthoma elasticum

Abstract

The objective was to report a case of pseudoxanthoma elasticum associated with type 2A idiopathic juxtafoveolar telangiectasis (T2AIJT) complicated by bilateral subretinal neovascular membranes (SRNVM). The right eye with juxtafoveal SRNVM and the left eye with subfoveal SRNVM underwent laser photocoagulation and photodynamic therapy respectively. The follow-up duration was 48 months. Best corrected visual acuity was 20/32 in both eyes at baseline, and 20/32 in the right eye and 20/200 in the left eye at the end of the follow-up. Atrophic changes in the retinal pigment epithelium developed around the SRNVM treated with photodynamic therapy (PDT). Pseudoxanthoma elasticum may be associated with T2AIJT complicated by bilateral SRNVM. Further studies are needed to assess both efficacy and appropriate PDT regime in T2AIJT-related SRNVM, especially if associated with other conditions.
