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...
OBJECTIVES Vitreoschisis is a possible pathogenic mechanism in macular diseases. Thus, the vitreoretinal interface was evaluated in monkey eyes and patients with various macular diseases in search of vitreoschisis. It is hypothesised that vitreoschisis is present in macular holes (MH) and macular pucker (MP), but not in other maculopathies. METHODS Histopathology was studied in 14 monkey eyes...
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 ...
