Abstract

Безлинзовый офтальмоскоп (21, 41), содержащий приспособление (22, 42), определяющее первый путь (a) распространения света, отражательное приспособление (23, 43), выполненное с возможностью отклонения света с первого пути (a) распространения света в направлении второго пути (b) распространения света, выходящего через первое окно (24, 44) и входящего в обследуемый глаз (29, 49), второе окно (25, 45), сквозь которое наблюдатель может наблюдать обследуемый глаз (29, 49) вдоль пути (d), проходящего, по существу, параллельно второму пути (b) распространения света, и экран (23, 26; 43, 46), установленный между первым путем (a) распространения света и вторым окном (25, 45), для предотвращения или, по меньшей мере, существенного ослабления любого света, выходящего из офтальмоскопа через второе окно (25, 45). В результате, весь свет, который может иначе проходить через второе окно (25) в глаз (30, 50) наблюдателя, устраняется или, по меньшей мере, существенно ослабляется, в результате чего существенно ослабляется паразитная засветка и улучшается видимость обследуемого глаза (29, 49) наблюдателем.Международная заявка была опубликована вместе с отчетом о международном поиске.
