[The effect of vitrectomy combined with full endocular panretinal photocoagulation in late proliferative diabetic retinopathy].
OBJECTIVE
To investigate the effect of vitrectomy combined with full endocular panretinal photocoagulation in patients with late stage of proliferative diabetic retinopathy (PDR).


METHODS
Pars plana vitrectomy combined with full panretinal photocoagulation were undergone in 56 eyes (56 cases) with late stage of PDR, including 32 eyes with tractive retinal detachment. Preoperative and postoperative visual acuity, anterior segment by slit lamp and fundus examination by indirect ophthalmoscopy, as well as fluorescein angiography (FFA) were analyzed.


RESULTS
Retina were reattached in 52 eyes. Vitreous hemorrhage, retinal bleeding, exudation and neovascular changes were not observed in these eyes. Non-irrigated areas were not found in 28/32 eyes in which FFA examination has been performed. Final visual acuity was improved in 52 eyes.


CONCLUSIONS
Full endocular panretinal photocoagulation with low energy is an effective and safe procedure with low rate of complications for the late stage of PDR.
