CASE REPORT We present the case of a 48 year-old man who had a sudden onset of vomiting, headache and loss of consciousness. The visual acuity was severely reduced in the left eye, with a large subhyaloid haemorrhage being observed in the fundus. DISCUSSION The combination of subarachnoid haemorrhage and a vitreous haemorrhage is called Terson syndrome. The details of the treatment of this ca...

A 36 year-old Malay lady with diabetes mellitus in pregnancy and poorly controlled hypertension developed rapid progression of diabetic retinopathy from no retinopathy to florid proliferative retinopathy over three months in her right eye. She had subsequent loss of vision due to vitreous haemorrhage in the peri-partum period. She had good final visual acuity with quiescent retinopathy followin...

PURPOSE Ocular toxoplasmosis is associated with vitreoretinal complications that can potentially cause severe visual loss. The aim of this study is to report the preoperative, intraoperative, and postoperative outcomes of vitreous surgery in eyes with vitreoretinal complications secondary to ocular toxoplasmosis. METHODS This retrospective study included 15 eyes of 15 patients (8 men, 7 women...

Dear Editor, Pars plana vitrectomy (PPV) using the 27-gauge transconjunctival approach is the last frontier of small gauge vitrectomy. Only 1 paper has been published so far describing the use of 27-gauge vitrectomy in a limited number of cases, including epiretinal membranes, idiopathic macular holes, diabetic vitreous haemorrhages, a vitreous biopsy for presumed vitreoretinal lymphoma and a f...

Swift, P. G. F., Worthy, E., and Emery, J. L. (1974). Archives of Disease in Childhood, 49, 680. Biochemical state of the vitreous humour of infants at necropsy. Biochemical analysis of the vitreous humour in 80 infants brought to necropsy, including 18 in whom terminal plasma levels were known, indicates that sodium and urea levels closely reflect ante-mortem plasma values. With increasing tim...

PURPOSE Pharmacologic vitreolysis is a promising new therapy to improve vitreoretinal surgery and, ultimately, prevent disease by mitigating the contribution of vitreous to retinopathy. The mechanism of action of the agents being developed for pharmacologic vitreolysis remains unclear. The experiments in this thesis test the hypothesis that pharmacologic vitreolysis agents break down vitreous m...

INTRODUCTION Progressive outer retinal necrosis (PORN) is a rare but devastating infectious retinitis associated with varicella zoster virus (VZV) and responsible for severe visual loss. CASE REPORT A 59-year-old man treated for generalized myasthenia with oral azathioprine and prednisone presented with severe unilateral necrotizing retinitis. Polymerase chain reaction of the aqueous and vitr...

To determine the mechanisms of vitreous liquefaction following vitreous hemorrhage, we investigated the effects of the free radicals produced by a bilirubin-sensitized photochemical reaction on collagen and hyaluronic acid (HA). Bovine vitreous collagen and HA were irradiated by visible light in the presence of bilirubin, which is produced from the degradation of hemoglobin, as a photosensitize...

purpose: to ascertain whether the use of nested-pcr (nested polymerase chain reaction) technique leads to more rapid and accurate diagnosis of bacterial endophthalmitis. methods: the aqueous humor and vitreous samples of 24 eyes of 24 patients with bacterial endophthalmitis were evaluated by microscopy, diagnostic aerobic culture, and nested- pcr to detect the infectious agent. results: aerobic...

BACKGROUND Capsule and pneumolysin (PLY) are two major virulence factors of Streptococcus pneumoniae. S. pneumoniae is one of the leading causes of bacterial endophthalmitis. The aim of this study is to determine whether passive immunization with the 23-valent pneumococcal polysaccharide vaccine (Pneumovax® 23; PPSV23) or PLY protects against pneumococcal endophthalmitis. METHODS New Zealand ...
