Frequency of Eye Diseases in Residents of Nursing Homes - 1-Year Results of a Novel Telemedicine Service in Switzerland.

Purpose: For the elderly in nursery homes, a visit to the ophthalmologist is a burden, which might lead to undertreatment. We have recently started offering a novel ophthalmological service combining onsite examination and telemedical interpretation for patients with limited access to ophthalmological care. This study summarises the frequency of findings of treatable eye diseases after the first year of operation in participants who dropped out from regular ophthalmological control.

Methods: Participants' clinical characteristics, frequency of service utilisation, and findings were extracted from the system and analysed.

Results: Of 1946 residents approached, 540 (27.7%; 1080 eyes) signed up for the service. A complete examination was possible in 412 persons (813 eyes) and partially possible in the remaining 128. The mean age of the examined participants mean age was 83.9 years (SD 9.7), and they were predominantly female (69.8%). The majority had a diagnosis of dementia (54.5%) and 20.2% had diabetes mellitus requiring treatment. The median care level (ranging from 0 - 12) was 7 (interquartile range 6 - 9), corresponding to a care need of 121 - 140 min/d. The mean best-corrected decimal visual acuity was 0.55 (SD 0.24). For 164 eyes (15.2%), the current spectacle correction was insufficient. An untreated cataract was present in 145 eyes (13.4%), 89 eyes (8.2%) were receiving glaucoma treatment, and 7 eyes had a decompensated glaucoma. Dry age-related macular degeneration (AMD) appeared in 276 eyes (25.6%), 12 eyes (1.1%) had wet AMD, and 24 eyes (11.0%) among patients with diabetes showed signs of diabetic retinopathy. Other pathologies were uncommon.

Conclusion: Residents of nursery homes, who are unable to attend regular ophthalmological control, show various treatable ophthalmological conditions, including cataracts, glaucoma, and retinal pathologies. Screening with a novel telemedicine service allows for the identification of treatable conditions and careful planning and referral of patients to appropriate clinics having the necessary infrastructure for this particular population.
