The origin of the term glaucoma is disputed. Its meaning through antiquity is also poorly understood. Today there are an increasing number of medications. But as yet we are still in the Dark Ages insofar as the cause of this visually disabling disorder.

Preoperative donor endothelial cell count does not affect the rate of dislocation in endothelial keratoplasty. The surgical technique is likely the most important factor that drives the dislocation rate, primary graft failure rate, and long-term endothelial survival, according to one surgeon.

Phakic IOL implantation has advantages as a method of refractive surgery. Enhancement may be needed to optimize the refractive result, but many issues should be considered before undertaking an enhancement and when offering this technology to potential candidates.

Results of a pivotal phase III trial of a cyclosporine A product for the treatment of vernal conjunctivitis (VKC) in children showed that the drug improved symptoms and signs of the orphan disease, and tolerability was excellent, according to the manufacturer.

A pooled analysis of three randomized, double-masked, placebo-controlled, conjunctival allergen challenge trials demonstrates that once-daily treatment with olopatadine 0.2% (Pataday, Alcon Laboratories) is equally effective for improving ocular itching caused by exposure to indoor or outdoor allergens.

Medical technology company Optos is collaborating with Eyemaginations to produce animations designed to enable eye-care professionals to educate their patients about diabetic retinopathy, retinal detachment, glaucoma, and choroidal nevi.

Progress in the diagnosis and treatment of retinoblastoma has been minimal over the past couple of decades, although improvements have been made, and new therapies are being studied, according to an ocular oncology expert.

Judah Folkman, MD, whose work in cancer research led to significant breakthroughs in treating age-related macular degeneration, is being remembered as the kindly and compassionate "father of angiogenesis."

Post-occlusion surge varies from phacoemulsification system to system based on several different parameters, including decreasing flow, increasing bottle height, decreasing tip gauge, and flow restriction. Randall J. Olson, MD, details recent research.

Co-management has come under fire from the federal government because of some instances of serious abuses. It can succeed when done correctly, however.

Implantable contact lenses appear to correct high myopia more accurately than customized all-laser LASIK, and the phakic lenses also provide a better quality of vision, according to results of a retrospective study of 79 consecutive eyes undergoing vision correction for high myopia.

Recipients of a premium IOL have high expectations for excellent uncorrected distance visual acuity. The availability of these implants has created a new patient base for laser vision correction. Considerations for performing laser enhancement are discussed.

Aspects of the intraoperative performance of two ophthalmic viscosurgical devices (OVDs) were prospectively evaluated during a single-surgeon, randomized study. Both agents worked well, but the results showed clear differences favoring a cohesive OVD of 1.6% sodium hyaluronate (Amvisc Plus, Bausch & Lomb) over a viscous-dispersive OVD of 4% chondroitin sulfate and 1.65% sodium hyaluronate (DisCoVisc, Alcon Laboratories).

The combination of torsional ultrasound and micro-coaxial phacoemulsification is ideal for cataract surgery because of the improved efficiency of the ultrasound system and the astigmatically neutral, highly competent 2.2-mm incision through which the highest-quality IOL can be implanted.
