Testing a New Model to Detect Preventive Vision Loss in People Over 70 with Chronic Conditions in General Practice

What this Trial Is About

Researchers are evaluating a model to identify and prevent vision loss among patients aged 70 years and older who have at least one chronic condition and are followed by a general practitioner GP. The study focuses on how general practice can help detect vision impairment early and coordinate care to reduce the burden of eye diseases such as glaucoma, age-related macular degeneration, cataract, and diabetic retinopathy. This intervention aims to improve timely access to eye healthcare through primary care involvement. The intervention includes three vision tests conducted in general practice the Collenbrander Mixed contrast card test for near vision, the Amsler Test for central vision, and a Visual Field Test for peripheral vision. After these tests, all patients receive a comprehensive vision assessment at local optician shops involving habitual vision testing, best corrected distance vision, intraocular pressure measurement, and ocular imaging including OCT scans and fundus photography. An ophthalmologist reviews all optometrist data and provides feedback to the general practice, managing urgent cases and referrals for further ophthalmologic follow-up as needed. Participants will complete a questionnaire and undergo vision tests in general practice before visiting optician shops for detailed assessments. Researchers will measure recruitment feasibility, patient adherence to the GP intervention and optometrist testing timelines, and acceptability through interviews within one year. The study also involves monitoring patient data and coordinating care between GPs and ophthalmologists to evaluate the models potential and limitations in real-world primary care settings. The total study period extends through July 2027.
