Abstract Details


To assess the efficacy of 35% DC Micropulse laser coagulation in targeting CNV feeder vessel in anti-VEGF frequent retreaters


Bogomolets National Medical University Kyiv Pechersk Ophalmological centre


15 patients (15eyes) were observed during 12 months. All patients underwent general ophthalmological examinations including OCT and OCT-A. All received anti-VEGF multiple injections (7,3 during past year) but no dry macular achieved. Mean VA was 0,3. Meant central macular thickness (CMT) - 322 mkm on OCT-A feeder vessels were identified. Micropulse 577 nm laser coagulation with 35% Duty cycle was performed over feeder vessel under OCT-A control.


Additional CMT decrease was achieved. Mean CMT after 12 months was 287 mkm. Mean IVT anti-VEGF decreased to 2,1 over observing period. VA remained stable (mean 0,3)


Micropulse laser coagulation in 35% duty cycle mode may be an option for feeder vessel coagulation. This allows to decrease number of IVT injections in frequent anti-VEGF retreaters groupe.
