Purpose: : To evaluate the potential of a sub-threshold, short pulsed, 810-nm diode laser for the treatment of chronic choroidopathy serous central.

Methods: : Five patients with chronic signals of central serous choroidopathy were treated. Following adjustment for individual chorioretinal pigmentation, micro pulsed laser envelopes of 180 µs (totalizing 300ms) in confluent spots were delivered to the pinpoint leakage in order to obtaining a security margin of 200 µm. For main outcome measures changes in ETDRS best correct visual acuity and central macular thickness obtained using optical coherence tomography were series-measured over a 6-months follow-up. Pre and post-treatment fluorescein angiography (FA) were evaluated.

Results: : No visible signs of treatment could be detected either on the eye fundus examination or FA. Improvement of 2 to 3 lines on the ETDRS chart was achieved in all patients. Exams demonstrated decreased exudation on fluorescein angiography, optical coherence tomography, and/or clinical examination. Central macular thickness decreased from a mean of 445 µm to 297 µm after 3 months of treatment. No procedure related side effects were observed.
