PURPOSE To assess the risks of vitrectomy for the removal of primary and secondary vitreous opacities. DESIGN Retrospective, nonrandomized, interventional case series. METHODS We reviewed the results of 116 consecutive cases of vitrectomy for vitreous floaters. Eighty-six cases were primary and 30 cases were secondary floaters. Main outcome measures were the incidence of iatrogenic retinal ...

Macular hole (MA) is a significant cause of visual acuity (VA) loss in patients over 50 years in our environment. The traction by the vitreous, particularly the posterior hyaloids, on the retina surface plays a leading role in the etiopathogeny of MA. The collagen fibers that comprise the posterior vitreous are firmly joined to the macula and connecting to the internal limiting membrane by mean...

PURPOSE To report a case of spontaneous resolution of idiopathic vitreomacular traction syndrome developed in a healthy young man. METHOD To exam the macular region using Optical coherence tomography (OCT). RESULT OCT examination revealed an incomplete posterior vitreous detachment (PVD) which remains broad vitreous adhesion at the macular area. The foveal thickness increase to 573 μm. The ...

A primate eye affected by postoperative infectious endophthalmitis was studied early in the course of the disease. Retinal perivasculitis, vitreoretinal adhesions along the inflamed vessels, and traction of the partially separated posterior vitreous on the retina at the adhesion sites were observed. It is suggested that such vitreoretinal junction pathology may be responsible for the developmen...

BACKGROUND To describe the prevalence and associations of posterior vitreous detachment (PVD) in a rural adult Chinese population. METHODS All eligible subjects were requested to carry out a comprehensive eye examination; PVD was a pre-specified outcome variable and was determined via biomicroscopical examination (slit-lamp biomicroscopy) with a +90-D preset lens after mydriasis. Prevalence w...

Preretinal and vitreous haemorrhages are commonly seen in proliferative diabetic retinopathy. They occur particularly at the stage of active growth of the new vessels (Stage II: Dobree, I 964), and are less frequently seen when connective tissue is being laid down in and around groups of new vessels. There is no doubt that repeated vitreous haemorrhages give rise to various forms of fibroplasia...

BACKGROUND We classified iatrogenic retinal break formation during 20-gauge pars plana vitrectomy for proliferative diabetic retinopathy into three types according to the mechanism of development, and evaluated the association of each type with postoperative complications. This is the largest series of such patients published to date. METHODS This was a retrospective comparative study of 760 ...
