Prostaglandin analogues get the job done
August 20th 2007Travoprost, latanoprost and bimatoprost all significantly reduce intraocular pressure (IOP) and increase ocular perfusion pressure (OPP) in patients with primary open angle glaucoma (POAG) or ocular hypertension (OHT), according to report published online ahead of print in Acta Ophthalmologica Scandinavica.
Preclinical study compares fluoroquinolones
August 1st 2007The efficacy of gatifloxacin and moxifloxacin for preventing methicillin-resistant Staphylococcus aureus (MRSA) keratitis was investigated in a rabbit model. Animals were pretreated with one of the two fourth-generation fluoroquinolones or BSS, received a midstromal injection with an inoculum of MRSA, and then study treatment continued for up to 96 hours postinjection. Gatifloxacin-treated eyes demonstrated less inflammation and infection, and lower numbers of recovered MRSA than moxifloxacin-and BSS-treated animals.
Fusion-protein anti-VEGF agent well tolerated for wet AMD; clinical improvements seem durable
August 1st 2007Intravitreal injection of up to 4 mg of a fusion protein that is an anti-vascular endothelial growth factor agent (VEGF Trap-Eye, Regeneron Pharmaceuticals Inc.) is well tolerated and yields no evidence of ocular inflammation. The agent appears to produce rapid and durable clinical increases in best-corrected visual acuity, along with improvements in anatomic features, in patients with neovascular (wet) age-related macular degeneration.
Bromfenac reduces severity, frequency of corneal discomfort
August 1st 2007The instillation of bromfenac 0.09% (Xibrom, ISTA Pharmaceuticals) results in less severe and less frequent patient discomfort compared with ketorolac tromethamine 0.4% (Acular LS, Allergan). However, the anesthetic effect of either commercially available nonsteroidal anti-inflammatory drug was statistically equivalent.
Topical azithromycin effective in P aeruginosa keratitis
August 1st 2007Treatment with topical azithromycin 1% ophthalmic solution (AzaSite, InSite Vision) using a frequent dosing regimen was effective in reducing colony counts of azithromycin-resistant Pseudomonas aeruginosa in an animal model of keratitis.
Nepafenac penetrates most quickly in NSAIDs study
August 1st 2007In a double-masked, randomized comparison of three leading ocular nonsteroidal anti-inflammatory agents, nepafenac 0.1% (Nevanac, Alcon Laboratories) had significantly greater ocular bioavailability than either ketorolac 0.4% (Acular LS, Allergan) or bromfenac 0.09% (Xibrom, ISTA Pharmaceuticals).
