Hypothesis
What is the prevalence and what are the determinants of glaucoma among citizens of Qatar aged 40 years or older?
Conclusion
The prevalence of glaucoma among citizens of Qatar aged 40 years and older was found to be 1.73%, with age and myopia being significant risk factors.
Supporting Evidence
- The age- and sex-adjusted prevalence of glaucoma was 1.73%.
- Chronological age of 60 years and older was a significant predictor of glaucoma.
- 5,641 individuals in Qatar aged 40 years and older are estimated to have glaucoma.
- 44 (65.7%) individuals with glaucoma were diagnosed with open-angle glaucoma.
- 36 (54%) subjects with glaucoma were treated.
Takeaway
In Qatar, about 1.73 out of every 100 people aged 40 and older have glaucoma, especially if they are older or have myopia.
Methodology
A community-based survey conducted in 2009 involving 49 randomly selected clusters, where demographic details and glaucoma history were collected, and ophthalmologists evaluated participants using various diagnostic tools.
Potential Biases
Potential bias due to the exclusion of severely ill or mentally challenged individuals and those who refused to participate.
Limitations
The study may not fully represent the population due to variations in participation across different age and gender groups.
Participant Demographics
The study included citizens of Qatar aged 40 years and older, with a notable representation of Qatari nationals.
