Bimanual phaco advantageous in cases of zonular dehiscence
May 15th 2005Proponents of bimanual microincision phacoemulsification (BMP) are discovering that the technique offers unique advantages over standard coaxial phaco in not only routine cases but also particular difficult and challenging procedures. In a previous article we covered the advantage of BMP in eyes that had undergone previous radial keratotomy. In this article, we will discuss the advantages in eyes with zonular laxity or frank zonular dehiscence.

Stem cell research may hold key to restoring neural function in glaucoma patients
May 4th 2005At this time there is no therapy that can restore vision after retinal ganglion cell (RGC) death in patients with glaucoma. However, stem cell-based treatments do have the potential to restore function in individuals with various neurodegenerative diseases, reported Keith R. Martin, MD, of Cambridge University, Cambridge, England, at the annual meeting of the Association for Research in Vision and Ophthalmology.
Confocal microscopy useful tool to evaluate corneal subbasal nerves after refractive surgery
May 4th 2005Most corneal subbasal nerves disappear immediately following PRK and LASIK and take several years to return to near preoperative densities, according to William M. Bourne, MD, who presented the effects of refractive surgery and topical glaucoma therapy on corneal nerve morphology during the Association for Research in Vision and Ophthalmology annual meeting.
More focus on quality of life in patients with age-related macular degeneration
May 4th 2005The quality of life in patients with age-related macular degeneration (AMD) is coming under increasing scrutiny in recent years compared with previous studies which focused primarily on intraocular pressure and visual field changes.
Statins for age-related macular degeneration: The jury is still out
May 4th 2005HMGCoA reductase inhibitors (statins) have been evaluated in a small study with the hope that the agents will slow the progression of age-related macular degeneration (AMD). Results between the medication and placebo group were not significant at 12 months, but there were too few patients to reach definitive conclusions.

Subgroup analysis suggests TTT benefit in eyes presenting with poor vision
May 4th 2005A subgroup analysis from the Transpupillary Thermotherapy of Occult Subfoveal Choroidal Neovascular Membranes in patients with Age-Related Macular Degeneration (TTT4CNV) study shows an increasingly beneficial effect of TTT over time in eyes with BCVA of 20/100 or worse, said Elias Reichel, MD.
Duke Macular Translocation Study group reports recurrence rates
May 4th 2005There is a low rate of recurrent choroidal neovascularization (CNV) over 2 years in eyes that undergo macular translocation surgery with 360-degree peripheral retinectomy (MT-360) for exudative age-related macular degeneration, said Claxton A Baer, MD.
