Intervention Type
Procedure
Intervention Name(s)
Triple therapy of vitrectomy, IVTA and grid/focal laser photocoagulation
Intervention Description
all pars plana vitrectomy were accompanied with removal of retinal Internal limiting membrane (ILM) around fovea in round fashion with a dimension of approximately 2 disc diameters.
IVTA was introduced at the end of surgery or on the next day (4mg in 0.1cc). Two weeks afterward, fluorescein angiography guided macular laser photocoagulation which consisted of direct photocoagulation on leaking microaneurysms and application of grid pattern laser was undertaken.
