Purpose:
Retinochoroidal anastamosis (RCA) is known to be associated with retinal angiomatous proliferans rather than idiopathic macular telangiectasia. The case report describes a rare association of bilateral RCA with type II idiopathic macular telangiectasia in an elderly woman.
Case Report:
A 65-year-old female patient presented with decreased vision in both eyes to the ophthalmology clinic. She was diagnosed with bilateral large serous retinal pigment epithelial detachments (PED). Atypical association of PED with IMT led to additional imaging, including fluorescein angiography (FA), spectral-domain optical coherence tomography (SD-OCT), and indocyanine green angiography (ICGA). Multimodal imaging analysis revealed characteristic signs of RCA such as the so-called kissing sign on SD-OCT. The patient was not offered any treatment due to the poor prognosis associated with the condition.
Conclusions:
Although more commonly associated with retinal angiomatous proliferans (type III neovascular age-related macular degeneration), RCA can present in type II IMT Stage 5.
