Nurses participate to geriatric evaluations for falling patients. For these patients, it is recommended to evaluate,especially, visual acuity but this is not currently done because it is difficult to systematically combine with an ophthalmologic consultation. The HAS french recommendations propose to detect visual acuity deficiency using Monoyer and Parinaud scales, without specifying the professional qualification. According to the nurse competence decree of State Graduates, "sensory disorders" screening is a "non-vulnerable" examination, and can be performed by nurses. Therefore, they can use these scales, after training. We propose to evaluate the correlation between visual acuity scores obtained by nurses in geriatric consultations and an ophthalmologist. This study should include 204 patients over 65 years, who have fallen at least twice in the last 12 months. These patients will benefit from an evaluation by an ophthalmologist, after the geriatric consultation.
The proposed study aims to test if Gunnar computer glasses provide any advantages, in comparison to no glasses, on the following aspects in computer-related office work: - Any enhancement on visual performance of basic visual function, including visual acuity, contrast sensitivity, color discrimination, etc. - Any enhancement on visual performance of typical office work, including reading, word-spelling check, number searching, or target identification. - Any benefit in objective viewing comfort measured with viewing distance, blink frequency, post-viewing pupil size. - Any benefit in subjective viewing comfort reflected on the questionnaire of viewing symptom survey. - Any benefit in viewing comfort and visual performance with increased environmental ventilation or under strong glare. - Any benefit in life quality from daily wearing (e.g., better comfort or sleep quality).
The aim of the EAGLE Study is to compare the efficacy of conservative medical treatment and local intraarterial fibrinolysis in patients with central retinal artery occlusion and to evaluate benefit and risk for the patient of both therapies.
