PurposeTo compare short-term anatomical outcomes observed in optical coherence tomography (OCT) between intravitreal injection (IVI) with anti-vascular endothelial growth factor (VEGF) agent aflibercept (IVA) and subthreshold micropulse laser (SML) therapy in chronic central serous chorioretinopathy (cCSC).MethodsThirty-nine eyes of 36 patients with symptomatic cCSC in this retrospective study received either IVA or SML between December 2020 and August 2022. Spectral-domain-OCT (SD-OCT) findings were compared between the two treatment groups in terms of central macular thickness (CMT), serous subretinal fluid (SRF) height, the presence of pigment epithelial detachment (PED) and subretinal hyperreflective foci (HF) at baseline and one-month follow-up visits.ResultsBoth groups showed significant reductions in CMT and SRF at one-month follow-up visit. However, there were no statistically significant differences between the IVA and SML groups. Complete SRF resolution was observed in 10 out of 21 and 7 out of 18 eyes in the IVA and SML groups, respectively; however, retinal pigment epithelial (RPE) damage remained persistent in patients with PEDs at baseline.ConclusionsBoth IVA and SML were effective in treating cCSC. IVA and SML treatments had comparable effects in reducing CMT and SRF in eyes with cCSC. Further prospective studies with larger sample sizes and long-term follow-up visits are warranted to identify the long-term efficacy.
