Panoptx launches new logo, new models, new technology
January 15th 2008Panoptx has launched a new logo with a stylized number 7, tied to a new brand (7EYE), along with a renewed emphasis on the treatment of dysfunctional tear syndrome (DTS) and servicing independent dispensaries that care for patients with DTS symptoms.
Randomized, masked trial finds IOP-lowering benefit from within-class, monotherapy switch
January 15th 2008The Bimatoprost Data Evaluation was a prospective, multicenter, investigator-masked study that randomly assigned 266 patients whose IOP was not adequately controlled with latanoprost 0.005% (Xalatan, Pfizer) to bimatoprost 0.03% (Lumigan, Allergan) or travoprost 0.004% (Travatan, Alcon Laboratories).
Comparison study: brimonidine fares well as add-on therapy
January 15th 2008In a comparison study of adjunctive medication for glaucoma therapy, the addition of brimonidine tartrate, a selective alpha-adrenergic agonist, to a prostaglandin analog achieved greater pressure-lowering than either of two carbonic anhydrase inhibitors.
OCT close to detecting progression of visual field damage
January 15th 2008Analysis programs for longitudinal assessment of glaucoma are advancing. A new optical coherence tomography software analysis program provides overlays of the retinal nerve fiber layer (RNFL) thickness plots as well as regression
BAK linked to ocular surface damage in animal studies
January 15th 2008Prostaglandin analogues preserved with benzalkonium chloride (BAK) can cause more extensive loss of goblet cells and a breakdown of cell-cell adhesions, which could increase the risk of ocular surface disease, according to findings from a pair of studies conducted in rabbits.
Tomograph a powerful predictor for glaucoma progression
January 15th 2008A proprietary retina tomograph (Heidelberg Retina Tomograph 3, Heidelberg Engineering) can help ophthalmologists differentiate patients at risk of progression to glaucoma from those patients who are not, based on structural and functional findings in the optic nerve and visual fields.
Trabeculotomy surgery maintains favorable profile
January 15th 2008A review of outcomes from 498 eyes that have undergone trabeculectomy ab interno surgery with a novel ablative device (Trabectome, NeoMedix) for open-angle glaucoma show that the procedure is very safe and maintains IOP in the range of 14 to 16 mm Hg.
Canaloplasty providing durable IOP control at 18 months
January 15th 2008Canaloplasty is being evaluated in a prospective study that enrolled 94 patients who were candidates for glaucoma surgery. The procedure was performed successfully in 74 patients (79%). Mean follow-up for the group is about 12 months, and more than half of the patients have been followed to 18 months. The results show well-controlled IOP and minimal complications.
SLT, ALT comparable in ability to lower IOP, research finds
January 15th 2008Selective laser trabeculoplasty (SLT) is comparable with argon laser trabeculoplasty (ALT) in its ability to lower IOP in patients with open-angle glaucoma, according to 5-year results of a randomized, controlled trial from the University of Ottawa reported at the American Academy of Ophthalmology annual meeting.
Risk factor is old concept with new level of acceptance
January 15th 2008The medical profession was slow to adopt the concept of the risk factor, which was born from the marriage of statistics and probability theory. Gradually, however, it has become central to medicine and science and will assume even more importance in coming years.
Medicare cut halted for 6 months; reprieve causes 'great uncertainty'
January 15th 2008A 6-month reprieve on a proposed 10.1% fee cut for ophthalmologists and other physicians who treat Medicare patients will cause "great uncertainty" for patients and physicians, according to the American Society of Cataract and Refractive Surgery.
Corneal implants can be part of ectasia treatment after radial keratotomy
January 1st 2008A woman aged 47 years underwent radial keratotomy 22 years ago. Her uncorrected vision was good for 5 years until she started experiencing progressive hyperopic astigmatism leading to extreme fluctuation and loss of correctable vision. She underwent a procedure combining corneal ring segments (Intacs, Addition Technology Inc.) with interrupted suture closing of her RK incisions.
