VITREOUS detachment is a constant accompaniment and thus a cardinal symptom of retinal detachment, the importance of which is being increasingly stressed by modern authors. It has been indicted as one of the causes of retinal detachment, its action being enhanced by vitreo-retinal adhesions, congenital or acquired. It is less known that all aphakic eyes show some degree of vitreous detachment, ...

AIMS To determine if prospective monitoring influences cataract surgical outcomes in east Africa. METHODS A prospective observational study of all routine extracapsular cataract extractions with posterior chamber lens implants carried out at Kikuyu Eye Unit, Kenya, between 1 January 1999 and 31 December 1999. RESULTS Out of 1845 eligible eyes 1800 were included in the study. Two months' fol...

PURPOSE Previous studies from this laboratory revealed that vitreous insulin-like growth factor biological activity increases in diabetes and that this change can precede the onset of proliferative diabetic retinopathy. The goal of this study was to characterize this phenomenon in an animal model of alloxan-induced diabetes. METHODS Swine made diabetic with intravenous alloxan were euthanized...

PURPOSE To determine levels of the chemokines CCL1/I-309, CCL2/MCP-1, CCL3/MIP-1alpha, CCL4/MIP-1beta, CCL7/MCP-3, CCL8/MCP-2, CXCL5/ENA-78, CXCL6/GCP-2, CXCL10/IP-10, and CXCL11/I-TAC in the vitreous humor and serum, from patients with proliferative diabetic retinopathy (PDR), proliferative vitreoretinopathy (PVR), and rhegmatogenous retinal detachment with no PVR (RD), and to investigate the ...

Most retinal detachments are preceded by a posterior vitreous detachment (PVD), which causes traction on the retina and, potentially, a retinal tear. The liquefied vitreous can then seep under the retina, causing it to detach. Retinal detachments may initially be localised, but without treatment they may progress and lead to irreversible vision loss. Early recognition and prompt referral are th...

Using pigmented rabbits, two fluorophotometric methods for measuring aqueous flow were compared. A corneal depot of dye was used to measure aqueous flow in one eye of each rabbit while the vitreous depot method of Johnson and Maurice was used to measure aqueous flow over the same period in the fellow eye. After intravenous administration of acetazolamide or mannitol, during the first hour after...

purpose: to investigate the incidence, mechanisms, characteristics, and visual outcomes of traumatic wound dehiscence following keratoplasty. methods: medical records of 32 consecutive patients with traumatic globe rupture following keratoplasty who had been treated at our center from 2001 to 2009 were retrospectively reviewed. results: the study population consisted of 32 eyes of 32 patients i...

Hyperosmolar solutions and digital massage are frequent adjuncts employed to minimize vitreous loss at cataract extraction (Scott, i962; Virno, Cantore, Bietti, and Bucci, I963; Murray and Tipler, I966; Guyton, I954; Kirsch and Steinman, I955). The former is effective in reducing vitreous mass during the time interval usually necessary to complete a lens extraction, but the latter may not have ...

PURPOSE To report the incidence of posterior vitreous detachment (PVD) after uneventful state-of-the-art small-incision phacoemulsification with implantation of a posterior chamber intraocular lens (PC IOL). SETTING Department of Ophthalmology, Ludwigshafen Hospital, Ludwigshafen, Germany. METHODS This prospective study evaluated the vitreous status of eyes by biomicroscopic examination, in...
