Despite recent advances in the medical management of diabetic retinal disease, there remain established indications for vitreoretinal surgery in the treatment of severe proliferative diabetic retinopathy. These include non-clearing vitreous hemorrhage and tractional retinal detachment. Advances in surgical instrumentation, technique, and experience have led to improved visual outcomes, as well as a corresponding decrease in the incidence of postoperative complications. However, the presence of systemic and ocular factors in diabetic patients increases the risk of adverse events compared to non-diabetic individuals...

Purpose: This study evaluated the outcomes of surgical cystotomy for recurrent diabetic cystoid macular edema (CME). Patients and methods: We analyzed 20 eyes with a clinical diagnosis of diabetic retinopathy and refractory CME. Release of vitreoretinal adhesion, epiretinal membrane (ERM) and internal limiting membrane (ILM) peeling and cystotomy guided by intraoperative optical coherence tomography (iOCT) were performed in every patient. Pars plana vitrectomy was also performed in 17 patients, 11 of whom also underwent lensectomy and intraocular lens implantation...

Conducted in the early 1990s Endophthalmitis Vitrectomy Study (EVS) have helped in establishing reasonable guidelines for the management of infectious postoperative endophthalmitis. However at present, more than 20 years after its publication, tremendous progress has been introduced in vitrectomy technology, which now permits the vitreoretinal surgeon to perform surgery more safely, and with better outcomes. Moerover, performing a complete vitreous removal, along with the moving up of the surgical intervention to as early as possible allows the prevention of complications that would limit the functional improvement postoperatively...

Silicone oil is the one of the artificial materials used in vitreoretinal surgery for retinal detachment treatment. Since the silicone oil is sometimes applied along with intraocular lens (IOL) implantation the direct influence of silicone oil on the artificial implant should be taken into account. Presented study was performed in order to determine the time-dependent impact of silicone oil on hydrogel based ophthalmic materials. Two kinds of IOLs based on hydroxyethyl 2-methacrylate (HEMA) hydrogel material were immersed in silicone oil based on linear poly(dimethylsiloxane) (PDMS)...
