“…Important features of the surgical procedure described here include: (1) removal of the posterior vitreous membrane that allows tissue fluids, such as subretinal fluid, to diffuse into the vitreous cavity; (2) removal of the posterior vitreous membrane, similar to diffuse diabetic macular edema, that reduces traction in a retinal tangential direction and allows the macular edema to be absorbed (Lewis et al 1992;Wolbarsht & Landers 1980); and (3) an increase in partial oxygen pressure in the vitreous cavity that enhances vasoconstriction with resulting regression of CNV (Hashimoto et al 2000;Pollack et al 1996).…”

ABSTRACT.Objective: In age-related macular degeneration, the posterior vitreous surface often remains attached to a higher degree than expected for the patient's age, suggesting the involvement of the posterior vitreous membrane in the pathophysiology of choroidal neovascularization. Thus, we performed simple pars plana vitrectomy and artificial posterior vitreous detachment in order to induce regression of choroidal neovascularization.

“…It has also been suggested that macular oedema tends to show actual worsening in eyes afflicted with DR at the time of cataract surgery. 14 Distinguishing transient oedema from substantial progression of maculopathy is important to the timing of treatment for the macular oedema, including laser photocoagulation, 31 vitrectomy, [32][33][34] and triamcinolone injection. [35][36][37] However, until recently, there had been no quantitative study to examine the progression of diabetic macular oedema after cataract surgery.…”

Purpose To quantitatively examine changes in macular oedema after phacoemulsification surgery in eyes with diabetic retinopathy (DR) and in eyes without DR. Methods Thirty-four eyes with DR and 34 eyes with no DR scheduled for phacoemulsification surgery were recruited. Foveal thickness and macular volume were measured using optical coherence tomography preoperatively and at 3, 6, and 12 months postoperatively. Grade of diabetic macular oedema was also examined. Results Preoperatively, there were no significant differences between groups in foveal thickness and macular volume. The foveal thickness increased by 20.3% in the DR group and by 6.0% in the no DR group at 3 months after surgery, but thereafter decreased gradually. When comparing the groups, the foveal thickness and macular volume were significantly greater in the DR group than in the no DR group at 3 months postoperatively. The grade of macular oedema worsened in eight eyes (23.5%) in the DR group, and in one (2.9%) in the no DR group: the incidence was significantly greater in the DR group (P ¼ 0.0272). However, the oedema that occurred after surgery resolved spontaneously in three (33.3%) of the nine eyes. Conclusions The degree of diabetic macular oedema increases up to 3 months after cataract surgery, but thereafter decreases gradually. Grade of diabetic macular oedema also worsens up to 3 months, but certain percent of macular oedema that occurs after surgery resolves spontaneously. These changes are more prominent in eyes with DR than in eyes with no DR.

“…In all, 10 patients with this syndrome were treated by vitrectomy and peeling of the posterior hyaloid, and 80% experienced significant visual improvement. 24 Subsequent uncontrolled series appeared to support this observation. Since then, vitrectomy has been attempted in eyes without evidence of traction, and indeed in even in eyes without attached gel.…”

The prevalence of diabetic retinopathy is increasing worldwide due to an increasing number, and prolonged survival, of diabetic patients. Many effective treatments for different types and stages of retinopathy exist. However, there is patchy delivery of care, inconsistent screening, and unresolved questions about several management questions. This article discusses the current state of knowledge about therapeutics in diabetic retinopathy, and highlights areas where further studies and evidence base is required.
