[Self-reported vision in (gerontological) health services research and practice-an opening plea]. / Selbstberichtetes Sehvermögen in der (gerontologischen) Versorgungsforschung und -praxis ­ ein Plädoyer zur Öffnung.

The use of self-reported vision is an integral part of most population surveys and is primarily used for healthcare monitoring. Since the patient's assessment is not always consistent with the objectively measured clinical parameters, the majority of the literature looks critically at the adequacy of self-reported vision, particularly with respect to answering epidemiological questions; however, it is often misunderstood that self-reported vision measures far more than the directly derived information show. This article shows the complexity of self-reported vision and discusses the importance of health services research and practice, with a special focus on the topic of vision in old age. From the explanations it becomes clear that the self-estimation of vision by a person is determined by various factors apart from the pure organ function and that the need for action and diagnostic conclusions can only be derived from self-reports. This is essential if vision is to be understood as a multifactorial condition and empirically practiced using different survey instruments. The article shows that self-reported vision is a good indicator of the quality of care in its entirety.

[Internet search for counseling offers for older adults suffering from visual impairment]. / Internet-Recherche nach Beratungsangeboten für ältere Menschen mit Sehbehinderung.

BACKGROUND: Visual impairment is a relevant problem of aging. In many cases promising therapeutic options exist but patients are often left with visual deficits, which require a high degree of individualized counseling. This article analyzed which counseling offers can be found by patients and relatives using simple and routine searching via the internet. METHOD: Analyses were performed using colloquial search terms in the search engine Google in order to find counseling options for elderly people with visual impairments available via the internet. RESULTS: With this strategy 189 offers for counseling were found, which showed very heterogeneous regional differences in distribution. The counseling options found in the internet commonly address topics such as therapeutic interventions or topics on visual aids corresponding to the professions offering rehabilitation most present in the internet, such as ophthalmologists and opticians. Regarding contents addressing psychosocial and help in daily tasks, self-help and support groups offer the most differentiated and broadest spectrum. Support offers for daily living tasks and psychosocial counseling from social providers were more difficult to find with these search terms despite a high presence in the internet. DISCUSSION: There are a large number of providers of counseling and consulting for older persons with visual impairment. In order to be found more easily by patients and to be recommended more often by ophthalmologists and general practitioners, the presence of providers in the internet must be improved, especially providers of daily living and psychosocial support offers.
