The invention is an eye viewing device having an eyepiece at an observer end thereof and an imaging element at an observation port thereof. Light that is reflected from an imaged eye of a patient is provided to either or both of the eyepiece and the imaging element. A practitioner can view the imaged eye, and can sequentially image the same region of the imaged eye for recording, documentation, and/or analysis.

Digital documenting ophthalmoscope

A handle for a diagnostic instrument includes a battery housing for retaining at least one rechargeable battery and a set of interchangeable adapters which can be selectively and releasably engaged with the housing to allow recharging of the battery through interconnection with an external power source, such as a wall outlet. The adapters are directly attached and detached to one end of the battery housing without requiring any disassembly or modification of the battery housing, allowing the instrument to be used either with or without an attached adapter.

Diagnostic instrument system

In an eye test apparatus of the type having a single examination area, an improved view port is disclosed having a view port casing and a mounting apparatus arranged so that the view port casing is movable between a first and second active positions. In a first active position, the casing receives a patient's forehead so that a patient's right eye is aligned with a examination area, and a second active position wherein a casing receives a patient's forehead so that a patient's left eye is aligned with the examination area. The casing is specially configured to occlude ambient light and to accommodate a patient wearing eyeglasses. The eye test apparatus may further have a position sensor system for sending the present position of the casing. In one embodiment of the invention, a control unit is provided which is responsive to the position sensor system so that administration of a test to a patient is permitted only if the casing is in an active position, and may further be made responsive to the sensor system so that data captured during the test by the control unit is automatically categorized according to which eye is currently being tested.
