Micropulse laser for glaucoma may hold promise as option in clinical setting
February 1st 2009In a small pilot study with limited follow-up, early application of micropulse laser trabeculoplasty (MLT) using a specific diode laser (IQ810, Iridex Corp.) appeared promising. Use of this multifunctional laser may have practical advantages in a clinical setting. Further study of the technology is needed to determine the role of MLT in the treatment of glaucoma.
Dry age-related macular degeneration antioxidant drop could be a significant advance
February 1st 2009A topical eye drop (OT-551, Othera) is being investigated to treat geographic atrophy in dry age-related macular degeneration.

Oral fenretinide investigated for dry age-related macular degeneration
February 1st 2009Oral fenretinide (Sirion Therapeutics) is being investigated in a phase II study as a treatment for advanced geographic atrophy associated with age-related macular degeneration. It is hypothesized that this agent may limit disease progression by preventing delivery of circulating retinol to the eye, thereby reducing the accumulation of retinol-derived metabolites that are toxic to the retinal pigment epithelium and photoreceptor cells.
Microincision vitrectomy surgery is gaining popularity
February 1st 2009Microincision vitrectomy surgery has rapidly gained increased popularity. It is associated with many advantages, but there have been some reports of disadvantages such as a significantly higher incidence of endophthalmitis postoperatively, though more recent reports do not substantiate this conclusion.
