Baseline Demographics, Rationale, and Methods of Jiri Eye Disease Incidence Study

Area of Science:

• Ophthalmology
• Epidemiology
• Population Genetics

Background:

• Long-term anthropological and biomedical research in the Jirel population.
• The Jirel pedigree is a valuable resource for genetic studies.

Purpose of the Study:

• To estimate the incidence of cataract, glaucoma, and retinal diseases.
• Focus on Jirel individuals aged 50 years and older.
• 10-year study period.

Main Methods:

• Population-based cohort study: Jiri Eye Disease Incidence Study (JEDIS).
• Follow-up of participants from the Jiri Eye Study (JES) aged 50+.
• Data collection every four years until 2028, using established JES clinical protocols.

Main Results:

• Baseline demographics: 690 participants (50.4% male, 49.6% female), average age ~62 years.
• 5-year follow-up completed by 483 participants (80% response rate).

Conclusions:

• Epidemiological data will elucidate the natural history of eye diseases in the Jirel.
• Findings will inform targeted healthcare programs for blindness prevention.
