The study, reported online June 20th in Ophthalmology, focused on the link between nearsightedness and open-angle glaucoma, the most common form of the disease. Dr. Nomdo Jansonius at the University Medical Center Groningen in the Netherlands and colleagues pooled data from 11 previous studies that included tens of thousands of people. They found that, overall, nearsighted people were about 90% more likely to develop open-angle glaucoma. Those with higher levels of myopia appeared to be at higher risk of glaucoma. The findings only show that nearsightedness and glaucoma often co-occur, not that one causes the other. Furthermore, the studies the authors included were heterogeneous in terms of patient ages and different diagnostic criteria. "The results are, in a sense, an average," and may not be applicable to every group of people, Dr. Barbara Klein of the University of Wisconsin-Madison, who worked on one of the studies included in the new review, told Reuters Health "A conclusion might be that persons with high myopia should have regular ophthalmic examinations," Dr. Klein said. At this point, however, the U.S. Preventive Services Task Force says there is too little evidence to recommend for or against glaucoma screening. SOURCE: Ophthalmology 2011.
