Selective retina therapy (SRT) selectively disrupts the retinal pigment epithelium (RPE) with minimal damage to the photoreceptors. Previous studies have shown SRT to be effective for resolving SRF, while causing only minimal collateral damage to the retina and vision.However, most patients included in prior studies had chronic CSC (≥3 months symptom duration) and SRT efficacy on acute CSC is not fully known.
The current study evaluated short-term treatment outcomes following SRT with real-time feedback-controlled dosimetry in Korean patients with acute idiopathic CSC.

Experimental: Treatment arm
Patients received selective retina therapy
Device: Selective retina therapy
The selective retina therapy (SRT) is a laser treatment to the retina using the R:GEN device (Lutronic, Goyang-si, South Korea).
Laser energy began at 80 µJ and was increased in 5-10 µJ intervals until the optimal energy delivery was confirmed by the RFD system. Following confirmation, the optimal laser energy was applied to fluorescein leakages. If the energy was indeed optimal at leakage points, laser shots were administered around the leakages. If the energy was not optimal at the leakage points, laser energy was again increased in 5-10 µJ increments until optimal energy delivery.
- Subretinal fluid [ Time Frame: 3 months after treatment ]Presence or absence of subretinal fluid which identified based on optical coherence tomography images.
- Visual acuity [ Time Frame: At diagnosis, at 1 month, and 3 months after treatment ]Changes in logarithm of minimal angle of resolution visual acuity during the follow-up, which measured using visual acuity chart.
