Low-intensity/high-density subthreshold microPulse diode laser for chronic central serous chorioretinopathy

Area of Science:

• Ophthalmology
• Retinal Diseases
• Laser Therapy

Background:

• Chronic central serous chorioretinopathy (cCSC) is a condition characterized by fluid accumulation under the retina.
• Management of symptomatic cCSC can be challenging, with varying treatment outcomes.
• Subthreshold laser therapy offers a less invasive approach to retinal conditions.

Purpose of the Study:

• To assess the efficacy of subthreshold 810-nm diode MicroPulse laser in treating symptomatic chronic central serous chorioretinopathy.
• To evaluate changes in visual acuity and macular thickness post-treatment.
• To determine the safety and feasibility of this laser modality for cCSC.

Main Methods:

• A retrospective, interventional case series involving 10 patients (11 eyes) with symptomatic cCSC.
• Treatment involved applying the subthreshold MicroPulse laser to areas of leakage, neurosensory detachment, or pigment epithelial detachments.
• Exclusion criteria included lack of follow-up, other macular diseases, steroid use, or prior alternative treatments.

Main Results:

• A statistically significant reduction in maximum macular thickness was observed post-treatment (mean decrease of 97 μm, P = 0.0046).
• Macular thickness decreased by a range of 20 μm to 338 μm.
• Visual outcomes and treatment session details were recorded for analysis.

Conclusions:

• Subthreshold diode MicroPulse laser treatment is a viable therapeutic option for managing symptomatic chronic central serous chorioretinopathy.
• The procedure demonstrated a significant impact on reducing macular edema.
• Further research may establish this as a standard treatment for cCSC.
