ARVO 2010 Abstracts - Glaucoma
Several presentations at the ARVO meeting represented the continuing endeavor to better understand the risk factors and pathophysiology of dry eye. Japan's Murat Dogru, MD, and colleagues demonstrated the role of dehydration in dry eye by comparing subjects drinking a controlled amount of alcohol n: Twelve hours after alcohol intake, substantial detrimental changes were observed in tear-function metrics e.
These results suggest substantial effects of alcohol on tear function. Dogru M, et al. Research efforts to enhance the understanding of the intricate relationship between visual function, blinking and dry eye were present in abundance across different groups of scientists and clinicians.

Researchers from SUNY College of Optometry demonstrated increased symptomatology following computer use compared to that reported after hard-copy fixation in a study of 24 participants. While these findings correlated to ocular surface disease severity, there was no apparent correlation to decreased blink rate. Chu CA , et al. ARVO E-abstract Our group presented results of its studies using customized video processing methodology to decipher blink patterns in dry-eye patients and normals, as well as to quantify the amount of corneal exposure which occurs between blinks in a new metric called the time-area Ocular Protection Index.
White R, et al. Clinical research models and results of clinical trials of developing therapies were also presented. Our group presented exciting data using the Enhanced Controlled Adverse Environment system, which has been used in a number of clinical trials in recent years, and represents the precision possible when using honed diagnostics and clinical trial design features.
Ousler GW, et al. Hsu H-C, et al. Komuro A, et al. ARVO E-abstract Finally, another study presented results of an ophthalmic anionic lipid emulsion containing HP-Guar, demonstrating potential as a novel artificial tear. Ketelson HA, et al.

In addition, a few intriguing examples of preclinical research with potential clinical application in the future emerged. Lubricin—a glycoprotein found in the cartilage of the knee—demonstrated reduced friction and tissue wear when tested using biomechanical machinery and human corneas and eyelids, which may suggest an advantage as an ocular surface lubricant. Schmidt TA, et al. ARVO E-abstract One group of researchers presented intriguing results of a mouse study demonstrating the potential of both vitamin D and its active metabolite 1, OH 2D to improve corneal epithelial barrier function, which may suggest clinical applications with further research.
Watsky MA, et al. Finally, prior to ARVO, expert clinical researchers, scientists, regulators, pharmaceutical executives, and venture capitalists interested in dry eye convened at the Dry Eye Summit, an event co-sponsored by our pharmaceutical consulting firm, Ora. Topics presented ranged from the history of dry eye, to defining dry eye, to clinical regulatory and exit strategies.
The summit imparted a business and regulatory spin to the discussion of innovations in dry-eye therapy. In a preclinical study, the combination of dexamethasone and povidone-iodine 0. FST reduced viral titers significantly more than placebo or Tobradex when all were applied q.
Titer reductions with FST were comparable with those seen with twice daily cidofavir 0. Animals were also scored for symptoms such as conjunctival and eyelid inflammation, exudates, excessive tearing and corneal neovascularization. The FST group had significantly lower scores i. Hill JM, et al. Besifloxacin was comparable to moxifloxacin and ciprofloxacin against H. Haas W, et al. As part of the body's natural defense against infection, granulocytes and monocytes produce NCT, a compound with anti-inflammatory and anti-infective activity.
NovaBay scientists examined the chemical stability, anti-microbial and antiviral activity of NVC in the presence of artificial tears. Najafi KK, et al. Romanowski EG, et al. ARVO E-abstract They used a rabbit model of ocular viral infection to show that ALA can significantly reduce the duration and severity of ocular infections. Gordon YJ, et al.

ARVO E-abstract While it wasn't as effective as the positive control cidofovir , it displayed little of the toxicity associated with currently available antiviral drugs, including cidofovir. Researchers reported interim results from a multicenter, open-label trial examining anti-TNF antibody adalimumab Humira, Abbott as a therapy for refractory uveitis. Treatment involved a 40 mg sc injection every two weeks and assessment of safety and efficacy over a week trial.
Inclusion in the study required diagnosis of noninfectious uveitis refractory to corticosteroids and at least one immunosuppressive. Endpoints included acuity improvement, de--creased intraocular inflammation and steroid tapering. Seventeen of 26 patients who completed the week trial responded positively to therapy, and 15 of these continued with treatment for 50 weeks. One initial responder discontinued treatment due to a loss of efficacy, and the only significant adverse event was unrelated to adalimumab.
Salom D, et al. Several other trials examined the use of monoclonal antibody mAb therapy targeting other immuno-modulators. Most of these agents were originally developed to treat systemic disorders but they have significant therapeutic potential in ocular inflammatory disease. An open-label study tested AIN, a humanized monoclonal directed against IL, for patients with noninfectious uveitis. Efficacy variables included acuity, vitreous haze, anterior chamber inflammation and reduction of corticosteroid dosing. Eight of 11 patients 73 percent with posterior segment uveitis and three of five patients 60 percent with anterior uveitis met the response criteria in this study.
Only one patient showed no response and required prednisone rescue.
Samson CM, et al. ARVO E-abstract Another study examined safety and efficacy of rituximab, an anti-CD mAb developed to treat B-cell lymphomas, for refractory scleritis and non-infective orbital inflammation. A total of 15 patients received rituximab infusion or 1, mg on days one and 15 of the study; followed by monthly safety monitoring and efficacy assessment at 24 and 48 weeks. The overall outcome was positive: Four patients were able to taper steroid dosing, and only one patient required increased steroids.
Vision was stable or improved in 14 patients, and patient and physician global health assessments also improved. The only significant safety issue involved seven of the first nine patients treated; they experienced inflammatory exacerbations after infusion that required adjunctive corticosteroids.
This didn't occur in the remaining six patients, nor has it occurred in the patients that have been re-infused since then.
