PURPOSE To compare the mydriatic effect and the short-term corneal endothelial safety of intracamerally injected N-methyl-3,4-dihydroxyphenylamine (epinine) to phenylephrine in a porcine eye model. METHODS One hundred twelve eyes from newly slaughtered pigs were used in this study. After pretreatment with 20 mg intracameral acetylcholine to give miosis, 0.15 mL epinine or phenylephrine 0.3%, ...

AIM To study the effect of intracameral injection of preservative-free lignocaine to induce pupil dilatation, without using any preoperative dilating eyedrops or intraoperative mydriatics in patients with age-related cataract associated with type 2 diabetes mellitus. DESIGN This was a prospective, observational, and interventional case series conducted at a tertiary eyecare center in rural In...

To report the clinical presentation and the role of intrastromal and intracameral voriconazole injection in the management of rare cases of fungal keratitis caused by Lasiodiplodia theobromae.Two eyes of 2 patients with Lasiodiplodia keratitis unresponsive to topical and oral antifungal medications were included in this study. Diagnosis of Lasiodiplodia keratitis was confirmed by microbiologica...

PURPOSE To determine the effects of the kappa opioid agonist, bremazocine (BRE), on intraocular pressure (IOP) and aqueous humor dynamics in normotensive cynomolgus monkeys. METHODS IOP, pupil diameter, refraction, aqueous humor flow, and mean arterial pressure (MAP) were measured following unilateral topical application of 1 to 100 microg BRE. IOP and MAP responses to 100 microg BRE were rep...

AIMS This study investigated the effect of tissue plasminogen activator (tPA) in patients with severe intracameral fibrin after extracapsular cataract extraction or phacoemulsification with posterior chamber intraocular lens implantation. METHODS A randomised prospective multicentre study was carried out in 86 patients with intraocular fibrin formation 2-8 days after cataract surgery. While t...

background: cataract extraction surgery remains the most commonly performed eye surgery by ophthalmologists. the maintenance of mydriasis is required throughout surgery to allow better visualization of the surgical field and a greater working space within the center of the eye. non-steroidal anti-inflammatory agents (nsaids) have their effect in maintaining mydriasis by their ability to inhibit...

PURPOSE To prospectively evaluate the effect of 1.25 mg and 2.5 mg intracameral bevacizumab on surgical outcomes of trabeculectomy for neovascular glaucoma (NVG), with primary outcome measures being the regression of neovascularization of iris (NVI) and reduction of intraocular pressure (IOP). METHODS Consecutive patients with neovascular glaucoma from December 2006 to March 2007 were randomi...

PURPOSE To investigate how topically instilled nipradilol penetrates the ipsilateral posterior retina-choroid in normal rabbit eyes. METHODS Albino rabbits were used. Topical instillation (1%, 100 microL) or intracameral (0.1%, 100 microL) or sub-Tenon injection (0.1%, 10 microL) of [(14)C]nipradilol was performed in one eye. Ocular and periocular distribution and the concentrations of [(14)C...
