Eye Disorder Screening May Get Boost From New Study
MONDAY, Aug. 2 (HealthDay News) -- Factors that increase the
risk of severe myopia (nearsightedness) and related vision loss
have now been discovered by researchers, and the findings may lead
to improved screening and treatment of people with the eye
Japanese researchers followed 429 patients with severe myopia
for an average of 12 years and found that a condition called myopic
maculopathy became significantly worse in 40 percent of the study
Among these patients, the types and patterns of abnormalities
that developed in the macula (the part of the eye that provides
clear, detailed vision) influenced the extent to which vision was
affected, the study authors explained in a news release from the
American Academy of Ophthalmology.
The study is the first to specifically describe the association
between disease pattern and vision loss. This knowledge could help
eye specialists identify which patients require the closest
monitoring, and help offer them the most appropriate treatments,
the researchers noted.
"Our findings suggest that a patient's age, degree of nearsightedness, eye (axial) length and a specific abnormal bulging of the back surface of the eye (a posterior staphyloma) may be important factors that affect the severity of myopic maculopathy," noted Dr. Kyoko Ohno-Matsui, of the Tokyo Medical and Dental University, and colleagues. "Also, our results show that in eyes that are likely to progress to serious disease, the first observable sign may be a tessellated fundus (a specific abnormality in the macula)."
The U.S. National Eye Institute has more about
myopia and other refractive errors.
