Efficacy and safety of subthreshold micropulse laser in the treatment of central serous chorioretinopathy accompanied by choroidal hemangioma: a case report.

Abstract

Background: Circumscribed choroidal hemangioma (CCH) is a benign vascular hamartoma caused by congenital vascular malformation. And, central serous chorioretinopathy (CSCR) is a chorioretinal disease characterized by pachychoroid, RPE irregularities, and subretinal fluid (SRF) accumulation. Some literature has indicated a potential correlation between the occurrences of CCH and CSCR.

Case presentation: A 59-year-old man presented with blurred vision in his right eye for six months, with an unremarkable history. Multimodal imaging techniques including color fundus photography, fundus autofluorescence (FAF), B-scan ultrasonography (USG), fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), and optical coherence tomography (OCT), revealed the presence of CCH accompanying CSCR in the right eye. The patient received treatment with SML for CSCR, while no specific treatment was administered for CCH. The SRF was fully resolved one month after the treatment. At the 3- and 6-month follow-up, SRF resolved, and best-corrected visual acuity (BCVA) improved from 0.6 to 0.9 in the decimal format in the right eye, without notable changes in subfoveal choroidal thickness (SFCT) or the size of CCH.

Conclusion: This case reported the coexistence of CCH and CSCR in the right eye, both characterized by choroidal vascular abnormalities. Further research is necessary to determine the favorable effect of SML in patients with CSCR and concurrent CCH.
