A 90-year-old man developed a hypopyon following cataract extraction with intraocular lens implantation. The hypopyon cleared with topical corticosteroid therapy but recurred whenever the corticosteroid therapy was reduced. At surgery for the removal of the intraocular lens an opaque anterior vitreous membrane was excised. Cultures of the anterior vitreous grew Staphylococcus epidermidis. The d...

BACKGROUND A new technique for visualisation of the vitreous base is described. It uses a standard lightpipe for scleral indentation and transillumination. Visualisation of the vitreous using low light levels can be achieved by enhancing the Tyndall effect. DISCUSSION Perfluorocarbon liquid (PFCL) is used to confine the aqueous environment to the anterior vitreous cavity and triamcinolone is ...

purpose: to present a case of ocular toxocariasis in a young male subject from the north of iran. case report: a 29-year-old man presented to our clinic with history of decreased vision in his left eye from 10 days before. he had a history of similar symptoms 2 years ago. visual acuity in the left eye was counting fingers at 2 meters but relative afferent pupillary defect was negative. the righ...

Purpose. To describe our surgical technique in the management of pseudophakic malignant glaucoma refractory to conventional treatment. Methods. Two pseudophakic eyes with malignant glaucoma underwent peripheral iridectomy, lens capsulectomy, hyaloidectomy, and anterior vitrectomy through a clear corneal incision by using a vitreous cutter. Results. Prompt resolution of malignant glaucoma was ac...

Total superoxide dismutase (SOD) activity was examined in the anterior humor of 32 diabetic patients and 34 nondiabetic controls during cataract extraction. Median age (95% confidence interval) was 77.5 yr (73.3-81.0) and 79.3 yr (76.0-83.2), respectively. The SOD activity also was examined in posterior vitreous sampled peroperatively in 10 diabetics with proliferative retinopathy and post-mort...

PURPOSE To report the short-term efficacy and safety of the transfer of an Ahmed(™) glaucoma valve (AGV™) tube from the vitreous into the anterior chamber, in a patient with neovascular glaucoma who had undergone pars plana AGV(™) implantation and ultimately needed a silicone oil tamponade. CASE A 41-year-old male with proliferative diabetic retinopathy in both eyes was referred to us for tre...

Posterior vitreous fluorophotometry measurements have been shown to be increased in patients with acute retrobulbar neuritis. We studied 12 patients who had optic neuropathy by posterior vitreous fluorophotometry, with and without correction for blood fluorescein concentration. Both uncorrected and corrected posterior vitreous measurements were increased in patients with inflammatory, obstructi...

With up to 6% of cataract surgeries complicated by vitreous loss,1 anterior vitrectomy is an essential skill of today’s cataract surgeon. Although the incidence of this complication is predictably higher in patients with complex cataracts due to pseudoexfoliation, intraoperative floppy iris syndrome, or posterior polar or dense cataracts, vitreous loss can occur unexpectedly in any case. To dec...

PURPOSE Vascular endothelial growth factor (VEGF) concentrations in various regions of the vitreous were examined in patients with diabetic macular edema (DME) to explore the possibility of a concentration gradient in the vitreous. METHODS Vitreous samples were collected during vitrectomy from 71 eyes of 71 patients with DME and without posterior vitreous detachment who had not undergone panr...

In 1865, Bowman was the first to recog­ nize the clinical entity of pupillary block, which he observed more frequently after cataract extraction without iridectomy than after cataract extraction with iridectomy. Bowman described this condition only as occurring shortly after discission of a sec­ ondary cataract. From his description it may be surmised that the mechanism in­ volved was obstructi...
