Frequent Tests Help Track Progression of Glaucoma, Study Finds
Their study, published online Aug. 8 in the journal Archives of Ophthalmology , included 381 glaucoma patients, aged 35 to 80, who were followed for anywhere from about 3 to 13 years. Glaucoma progression was more likely to be detected in patients who had more visual field tests (a median of 20) than in those with fewer tests (a median of 12).
"In summary, we found that a twice-yearly schedule of visual field testing resulted in earlier detection of glaucoma progression compared with a yearly schedule, especially with global trend analyses," wrote Dr. Kouros Nouri-Mahdavi and colleagues at the Jules Stein Eye Institute at the University of California, Los Angeles, in a journal news release.
"Validation of these findings in other patient populations would be desirable. Our results have significant health care policy implications with regard to determining the frequency of visual field testing in patients with glaucoma," they added.
One expert agreed that more frequent testing would end up helping patients.
"Glaucoma is one of the leading causes of blindness worldwide," noted Dr. Mark Fromer, an ophthalmologist at Lenox Hill Hospital in New York City. "Left untreated, patients will suffer a permanent loss of vision. This disease is treatable with both topical medications, laser therapy and microsurgery."
He said the new study "has wide implications for the detection of disease in millions of patients."

Hayreh and Zimmerman 6 had documented less severe visual field loss for diabetic patients with NAION. However, 11% of their participants had juvenile diabetes, 36% had diabetic retinopathy, and the investigators had used manual kinetic perimetry.
8 (HealthDay News) -- Frequent visual field testing may help doctors detect progression of the eye disease glaucoma at an earlier stage, a new study says. It's important to identify patients whose disease is progressing faster so that they can receive
Earlier studies demonstrated that a loss or irregularity of the IS/OS junction observed by OCT corresponded well with the visual field defects even at the early stages of AZOOR, 2-5 and the abnormality in the IS/OS junction can improve following

Intraocular pressure variation predicts visual field loss in ...
“Relatively easy to capture and display measures of IOP variation during treatment – the standard deviation (SD), range, and maximum IOP – should be reviewed during routine follow-up of glaucoma patients, as they are predictive of progressive loss of visual field,” Dr. David C. Musch from University of Michigan, Ann Arbor, Michigan told Reuters Health in an email. “This reinforces the need not only to assess a patient’s current status, but also to take time to review the patient’s IOP history.” “Perhaps somewhat hidden within the paper’s results is the fact that increased IOP variation during treatment was significantly predicted by a demographic factor – the patient’s race (blacks at greater risk) – by a clinical factor – the patient’s baseline IOP (higher IOP at greater risk), and by a center effect (centers differed in the extent of IOP variation their patients showed),” Dr. Musch said. “Underlying the observation of increased IOP variation is a complex milieu of factors, among which include insufficient adherence to treatment, difficulties with delivering a prescribed topical agent, differential response to treatment, and inadequate efficacy of the treatment itself.” “We are continuing to glean valuable insights from the data we collected during a clinical trial of initial treatments for glaucoma, with grant support from the NIH/NEI,” Dr. Musch added. “Other investigators are actively pursuing ways to intervene with novel devices or minimally invasive surgical approaches for managing patients whose IOP is insufficiently controlled by medical therapy.
