“…Nevertheless, several studies have reported that results from calculated binocular visual fields are consistent with the results found when an Esterman binocular visual field test is performed. [35][36][37][38] The assessment of incident falls with 4-month follow-up postcards may not be optimal, because it may be subject to recall bias. In addition, inattention during visual field testing may be a cause of misclassification error, because participants who do not pay attention during the visual field test may miss more points.…”

OBJECTIVES: To examine the relationship between binocular visual field loss and the risk of incident frequent falls in older white women. DESIGN: A multicenter, prospective cohort study. SETTING: Four clinic centers within the United States in Baltimore, Maryland; Minneapolis, Minnesota; Portland, Oregon; and the Monongahela Valley, Pennsylvania. PARTICIPANTS: Four thousand seventy‐one community‐dwelling white women aged 70 and older participating in the Study of Osteoporotic Fractures. MEASUREMENTS: Primary outcome was incident frequent falls, defined as two or more falls within 1 year. Primary risk factors were binocular visual field loss, distance visual acuity in the better eye, and contrast sensitivity at low spatial frequency in the better eye. RESULTS: Of 4,071 women, 409 (10%) had severe binocular visual field loss at the eye examination, and 643 (16%) experienced frequent falls within 1 year after their eye examination. Severe binocular visual field loss was significantly associated with frequent falls when adjusting for age, study site, and cognitive function (odds ratio=1.50, 95% confidence interval=1.11–2.02). The data showed a trend for increasing odds of two or more falls with greater binocular visual field loss (P<.001). In older white women with severe binocular visual field loss, 33.3% of frequent falls were attributable to visual field loss. CONCLUSION: Women with binocular visual field loss are at greater risk of future frequent falls. Screening for binocular visual field loss may identify individuals at high risk of falling.

“…The detailed description of binocular visual field loss was adapted from a scoring system of the integrated visual field, whereby uniocular visual field analyses are integrated into a single binocular field without additional testing, reported by Crabb and colleagues. 89,90 The definitions of health states are described in Table 1. According to whether the individual has or has not got glaucoma, he or she would start in the model in a normal state or in an undiagnosed glaucoma state.…”

“…This was by a grading of the binocular visual field using the integrated visual field method as described by Crabb and colleagues (see Table 1, p. 17). 89 The responses to the EQ-5D were converted to health state utilities using UK population tariffs and analysed according to the objective and subjective assessment of glaucoma severity (Kilonzo M, University of Aberdeen: personal communication, 2006). Table 44 shows the estimates of utility for those people with an objective assessment of their glaucoma severity.…”

Or contact Direct Mail Works (see contact details above) by email, post, fax or phone. HTA on CD is currently free of charge worldwide.The website also provides information about the HTA Programme and lists the membership of the various committees. HTA NIHR Health Technology Assessment ProgrammeT he Health Technology Assessment (HTA) programme, now part of the National Institute for Health Research (NIHR), was set up in 1993. It produces high-quality research information on the costs, effectiveness and broader impact of health technologies for those who use, manage and provide care in the NHS. 'Health technologies' are broadly defined to include all interventions used to promote health, prevent and treat disease, and improve rehabilitation and long-term care, rather than settings of care. The research findings from the HTA Programme directly influence decision-making bodies such as the National Institute for Health and Clinical Excellence (NICE) and the National Screening Committee (NSC). HTA findings also help to improve the quality of clinical practice in the NHS indirectly in that they form a key component of the 'National Knowledge Service'. The HTA Programme is needs-led in that it fills gaps in the evidence needed by the NHS. There are three routes to the start of projects. First is the commissioned route. Suggestions for research are actively sought from people working in the NHS, the public and consumer groups and professional bodies such as r...

“…Mogą one być szczególnie ważne u tych starszych osób, które albo nie są świadome zmian następujących w organizmie, albo nie chcą przyznać, że nie spełniają już wymagań nie tylko wzrokowych, ponieważ nie chcą zrezygnować z prowadzenia pojazdu (29). Pacjenci z ubytkami w polu widzenia spowodowanymi jaskrą, chorobami siatkówki lub zaćmą dwukrotnie częściej są sprawcami wypadków lub wykroczeń drogowych w porównaniu z osobami z pełnym polem widzenia (30). Obecnie coraz częściej używany jest termin 'przydatne pole widzenia' -UFOV (useful field of view), szczególnie w odniesieniu do pacjentów w starszym wieku, u których najczęściej spotykane jest zaburzenie tej funkcji wzrokowej.…”

StreszczenieNarząd wzroku jest dla kierowcy podstawowym narządem zmysłu. Jego stan warunkuje prawidłowe, komfortowe i bezpieczne wykonywanie tego rodzaju pracy. W artykule przedstawiono czynniki mogące wpływać na funkcje układu wzrokowego. Omówione zostały zarówno uwarunkowania zewnętrzne (środowisko, charakter i czas pracy, stres związany z jej wykonywaniem), jak i wewnętrzne (zaburzenia systemowe i miejscowe). Wszystkie wymienione czynniki mogą znacznie obniżać funkcje wzrokowe ważne dla kierowców, takie jak ostrość wzroku, pole widzenia, widzenie barwne, widzenie stereoskopowe i widzenie zmierzchowe oraz wrażliwość na olśnienie. Ponadto przedstawiono aktualne wymagania stawiane kierowcom różnych kategorii oraz przyczyny wypadków w róż-nych grupach wiekowych. Obniżenie funkcji wzrokowych może okazać się niebezpieczne zarówno dla kierowcy, jak i innych użyt-kowników dróg. Med. Pr. 2013;64(3):419-425 Słowa kluczowe: wzrok, kierowca, choroby oka, zmęczenie oka, środowisko pracy AbstractSight is the basic sense for drivers. Condition of the eye determines correct, comfortable and safe performance of the work as drivers. This article presents various factors influencing the sight condition. There are two groups of factors, external (environment, the kind and time of work, stress caused by work) and internal (systemic and local disorders). All these factors can reduce significantly visual functions, such as visual acuity, field of vision, color vision, strereoscopic vision, twilight vision and glare sensitivity. There are also presented actual requirements for drivers and causes of the car accidents in various age groups. Impairments in vision functions can be dangerous for both the driver and other road users.

Kierownik projektu: prof. dr hab. n. med. Alicja Bortkiewicz. WSTĘPZmysł wzroku pełni u ludzi bardzo istotną rolę, ponieważ dzięki niemu powstaje i jest modyfikowana wiedza o naszym otoczeniu. Nośnikiem informacji jest światło, które jest falą elektromagnetyczną o długoś-ci 380-770 nm. Ten wąski zakres promieniowania jest najbardziej przydatny i niezbędny, ponieważ ma właści-wości pobudzania receptorów siatkówki ludzkiej i wytwarzania w ten sposób wrażeń wzrokowych w ośrod-kowym układzie nerwowym. Są one następnie zapamię-tywane i przekształcane oraz ponownie wyprowadzane do otoczenia w postaci reakcji. Budowa oka sprawia, że promień świetlny przechodząc przez wszystkie ośrodki optyczne, w możliwie najmniejszym stopniu ulega odbiciu i pochłanianiu. Z kolei siatkówka, która ma przehttp://dx
