rainage devices are an efficient surgical treatment for esistant glaucoma or when previous filtrating surgery fails. here are 2 types of these devices: those comprising valves, n which the device includes a restriction at the outlet of he aqueous, and devices without valves in which the tube onnects with a dish without any type of restriction. Of the ormer, the best known is the Ahmed implant, ...

Aciclovir is rapidly absorbed from the ophthalmic ointment through the corneal epithelium and superficial ocular tissues with the result that viral toxic concentrations are achieved in the aqueous humor. It has not been possible to detect aciclovir in the blood by existing methods after topical application of ZOVIRAX Ophthalmic Ointment, but trace quantities are detectable in the urine. These l...

BACKGROUND/AIMS To compare the penetration of levofloxacin, ofloxacin and ciprofloxacin in the aqueous humour of eyes with functioning filtering blebs. METHODS In this investigator-masked study, 48 patients with functioning filtering blebs requiring cataract surgery were randomised into six groups of eight patients. Groups 1, 2 and 3 received topical ofloxacin 0.3% (Ocuflox), ciprofloxacin 0....

Aqueous extract of C. longa when administered 4 h after induction of E. coli lipopolysaccharide-induced uveitis in rats showed significantly suppressed inflammation with a significantly lower mean clinical grade, histopathological grade and aqueous humor (AH) protein level compared to vehicle treated group. Although, prednisolone group showed significantly lower clinical grade, histopathologica...

Patients due for cataract extraction received 5 doses of 400 mg acyclovir (Zovirax) orally during the 24 hours prior to surgery. Aqueous humour levels of acyclovir (mean 3.26 microM) were well above the normal ED50 range for herpes simplex virus type 1, and showed a significant correlation with plasma concentrations (mean 8.74 microM). There was also a correlation between the age of the patient...

PURPOSE To investigate the aqueous and vitreous penetration of levofloxacin, the drug was administered topically and/or orally to patients undergoing vitrectomy. METHODS Thirty-six patients undergoing initial vitrectomy with phacoemulsification and aspiration (PEA) were enrolled, and were divided randomly into three groups. Group 1 was treated with topical application of levofloxacin (three t...

The peripheral and central neural actions of clonidine on normal and glaucomatous eyes have been investigated. Threshold doses of clonidine applied topically induced a monotonic decrease of intraocular pressure in the treated eye and had no effect on the contralateral eye. With increased clonidine dose, a decrease of intraocular pressure occurred in the untreated eye, and there was a concomitan...

We report a case of posterior scleritis effectively managed with intravitreal bevacizumab. A 71-year-old woman was diagnosed with posterior scleritis. Although she was initially treated with systemic steroids, her clinical presentation deteriorated. She was then treated with a single intravitreal injection of bevacizumab and aqueous humor collection. The aqueous level of vascular endothelial gr...

This article considers how humor may fit within a resiliency perspective. Following a brief overview of resiliency approaches, including selected work on positive psychology, several lines of research that provide initial support for resiliency effects of humor on stress and trauma are highlighted. This work ranges from anecdotal case report descriptions of facilitative humor use in extremely t...

OBJECTIVE To evaluate the plasma and aqueous humor disposition of prednisolone after oral administration in cats. METHODS Six cats were administered with a single oral dose of prednisolone (10 mg). Blood and aqueous humor samples were serially collected after drug administration. Prednisolone concentrations in plasma and aqueous humor were measured at 0.25, 0.5, 1.0, 1.5, 2.0, 3.0, 4.0, and 5...
