Abstract
Objective:
To determine the association between physical activity and severity of
primary angle closure glaucoma in Malay patients.
Methods:
A cross-sectional study was conducted involving 150 primary angle closure
glaucoma patients between April 2014 and August 2016. Using the
International Physical Activity Questionnaire, the physical activity status
was assessed and divided into three categories: mild, moderate and heavy
physical activity. The duration of physical activity and corresponding
minimum energy requirements were calculated. Ocular examination was
performed including Humphrey visual field 24-2 analysis assessment. Based on
two consecutive reliable Humphrey visual fields, the severity of glaucoma
was scored according to modified Advanced Glaucoma Intervention Study and
classified as mild (0–5), moderate (6–11) and severe (12–20). Association
between physical activity and Advanced Glaucoma Intervention Study score was
determined with multiple linear regression analysis.
Results:
A total of 150 Malay patients with primary angle closure glaucoma were
included (50 patients with mild, 50 with moderate and 50 with severe
glaucoma). Physical activity showed inverse association with the severity of
primary angle closure glaucoma. After calculating adjustments for age, sex,
duration of glaucoma, body mass index, systemic co-morbidities, family
history of glaucoma, myopia and educational status [adjusted
b –3.41, 95% confidence interval (–5.23, –1.59),
p < 0.001], there was also an inverse relationship
with Advanced Glaucoma Intervention Study score. Every increase in physical
activity level reduces the Advanced Glaucoma Intervention Study score by 3.4
point.
Conclusion:
Physical activity is the potential modifiable risk factor in reducing the
severity of glaucoma among primary angle closure glaucoma patients. However,
there is possibility of the severity of glaucoma restricted the physical
activity of primary angle closure glaucoma patients.
