Air tamponade in retinal detachment surgery followed by ultra-widefield fundus imaging system.

Aim: To report the surgical result of pars plana vitrectomy (PPV) with air tamponade for rhegmatogenous retinal detachment (RRD) by ultra-widefield fundus imaging system.

Methods: Of 25 consecutive patients (25 eyes) with fresh primary RRD and causative retinal break and vitreous traction were presented. All the patients underwent PPV with air tamponade.

[The conversion of macular function in diabetic macular edema after vitreous surgery].

Objective: To evaluate the conversion of macular function in diabetic macular edema (DME) after vitreous surgery.

Methods: Seventeen eyes of 16 patients were assessed after pars plana vitrectomy for DME. Multifocal electroretinogram (mfERG) techniques were used to evaluate the effects of treatment on macular visual function, and retinal foveal thickness was determined by optical coherence tomography before and after vitrectomy.

[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.
