Effective Focal Laser Photocoagulation for Persistent Central Serous Chorioretinopathy: A Forgotten Technique

Abstract

We report a case of a patient with persistent central serous chorioretinopathy (CSC) who was on the waiting list for half-dose photodynamic therapy (PDT). As the patient's visual function began to deteriorate, patient opted for focal laser photocoagulation (FLP) targeting the presumed leakage site in the superior part of the macula. One month after the FLP treatment, there was complete resolution of SRF accompanied by improved visual function. In light of global verteporfin shortages, limited access to PDT centers, and poor efficacy from other treatment modalities, FLP emerges as an effective treatment option for CSC patients with extrafoveal leakage. Yet, many CSC patients with extrafoveal leakage, who could be effectively treated with FLP, are often merely monitored, experiencing fluctuating SRF and a gradual, irreversible vision decline. Despite FLP's historical presence in CSC treatment, our case serves as an important reminder for retinal specialists to reconsider this treatment approach in selected CSC patients.

Laser Treatment of Central Serous Chorioretinopathy – An Update

“…As the LPC endpoint is a chorioretinal scar, it is recommended to wait for 3-4 months before application of a laser in the expectance of spontaneous remission. Effects of classic photocoagulation of CSCR are nowadays analyzed rather seldom, however; this forgotten technique is still effective in selected persistent cases of CSCR [8]. Results of the studies employing conventional LPC are presented in ▶ Table 1.…”
