Tonometry reliability questioned
April 25th 2008Although tonometry remains a vital tool in glaucoma management, the significance of individual measurements should be regarded with a healthy degree of skepticism. Central corneal thickness (CCT) measurements should be incorporated into global assessment of glaucoma risk, but trying to correct tonometry readings by CCT is not appropriate.
Visual field testing: timing and analysis in patients with POAG
April 25th 2008The periodic assessment of vision function with visual field testing is a standard and important part of the management of primary open-angle glaucoma (POAG). Automated achromatic static threshold perimetry is the preferred technique, although other static and kinetic techniques are acceptable alternatives in patients who are unable to complete automated perimetry reliably or when the technology is not available.
FDA approves expansion of NeoVista's Phase III CABERNET trial
April 23rd 2008The FDA has approved an expansion of the Phase III CABERNET (CNV Secondary to AMD Treated with BEta RadiatioN Epiretinal Therapy) trial, which is evaluating the safety and efficacy of NeoVista's epiretinal brachytherapy in wet age-related macular degeneration (AMD).
Arsenal of strategies enables safe surgery in IFIS eyes
April 21st 2008Cases of intraoperative floppy iris syndrome (IFIS) encompass a wide spectrum of severity, so it is important for surgeons to master several different strategies to increase the likelihood of achieving a safe outcome in these eyes.
Eye drop contamination comes from bottle, not solution
April 18th 2008Bottles of infected eye drops are more likely to be contaminated with bacteria at the bottle tip and not within the solution, according to a study presented at this year's American Society of Cataract and Refractive Surgery (ASCRS) meeting.
Update and clinical pearls from the TVT study
April 18th 2008The Tube versus Trabeculectomy (TVT) Study found that nonvalved tube shunt surgery was more likely to maintain IOP control and avoid persistent hypotony and reoperation for glaucoma than trabeculectomy with mitomycin C (MMC) during the first year of follow-up.
Human embryonic stem cells have potential to treat retinal degeneration
April 16th 2008Regeneration of damaged retinal cells with the aid of stem cells may offer hope for the treatment of retinal degeneration conditions, such as age-related macular degeneration (AMD) and diabetic retinopathy (DR), according to a report published by the National Academy of Sciences (Volume 103).
AMD linked to increased incidence of death from stroke, cardiovascular events
April 16th 2008Age-related macular degeneration (AMD) may be a useful indicator for predicting death from stroke or cardiovascular disease, according to a study published online ahead of print by the British Journal of Ophthalmology.
Post-LASIK quality of life to be officially assessed
April 14th 2008A new study assessing the quality of life after LASIK is to be conducted by the American Society of Cataract and Refractive Surgery (ASCRS), the American Academy of Ophthalmology, the FDA and the National Eye Institute, it was announced at this year's ASCRS meeting in Chicago, US.
Xibrom 0.09% and 0.18% formulations "nearly identical"
April 14th 2008A clinical trial of Xibrom (bromfenac sodium ophthalmic solution; ISTA Pharmaceuticals) has demonstrated equivalence of end-point achievement between the 0.18% and the 0.09% formulations, according to topline results published by ISTA Pharmaceuticals.
Triamcinolone shown to raise IOP and cause gonioscopic changes
April 11th 2008Intraocular pressure (IOP) rises significantly and rapidly in eyes that have received an intravitreal injection of triamcinolone acetonide (IVTA), according to a study published in the March issue of the Journal of Ophthalmology.
