Abstract Details

Purpose:

To investigate the prevalence of open-angle glaucoma (OAG) in myopia by age.

Setting:

A cross-sectional study using a stratified, multistage, probability cluster survey. International Society of Geographical and Epidemiological Ophthalmology, Korea

Methods:

Participants of the Korean National Health and Nutrition Examination Survey between 2010 and 2011. A standardized protocol was used to interview and perform comprehensive ophthalmic examinations on every participant. Glaucoma was diagnosed according to the International Society of Geographical and Epidemiological Ophthalmology criteria.

Results:

There is a positive correlation between OAG prevalence and increasing myopic refractive error, except in subjects with hyperopia. Compared to those with emmetropia, OAG patients under the age of 40 had higher odds of also having high myopia (odds ratio 3.24, 95% confidence interval 1.61–6.53). OAG prevalence in patients under the age of 40 with high myopia(5.3%) was comparable to the overall prevalence of OAG(5.2%)(p=0.955). The prevalence of OAG in 19-29years old with high myopia(2.8%) was comparable to that of emmetropia in patients 30-39years old(2.6%)(p=0.892). OAG prevalence in 30-39years old with high myopia(8.3%) was higher than that with emmetropia(3.3%) and mild myopia(3.4%)(p=0.008, p=0.017, respectively) and comparable to with moderate(4.9%) and high myopia(10.6%)(p=0.206, p=0.565, respectively) of patients 40-49years old.

Conclusions:

These data suggest that OAG may develop earlier in patients with high myopia than it does in others. There is high prevalence of OAG in patients with high myopia, even those 19-29 years old. Therefore, OAG screening should be performed earlier in patients with high myopia than it is according to the traditional guidelines.
