Abstract
An eye testing system for diagnosing age-related macular degeneration of a patient is disclosed. The eye testing system includes a plurality of acuity charts arranged in a plurality of rows. The each acuity chart includes a plurality of rows of symbols. Further, the eye testing system includes a bulls eye configured to slide relative to the plurality of acuity charts. The bulls eye includes a telescopic arm and an eye portion attached to the telescopic arm to facilitate a viewing of the one or more symbols to facilitate in diagnosing a central vision and a peripheral vision of the eye of the patient.
Claims15
An eye testing system for diagnosing age-related macular degeneration of a patient, the eye testing system comprising:
- a plurality of acuity charts arranged in a plurality of rows, each acuity chart includes a plurality of rows of symbols;
- and
- a bullseye configured to slide relative to the plurality of acuity charts and having a telescopic arm and an eye portion attached to the telescopic arm to facilitate a viewing of the one or more symbols to facilitate in diagnosing a central vision and a peripheral vision of the eye of the patient;
- and
- the separated filter rack eyepiece as described herein and in Arnow'542 so to make a complete eyepiece and objective system for AMD testing.
An embodiment wherein the filter eyepiece assembly therein is affixed to the head with sterilizable straps going around the head and a sterilizable, ergonomic interface between the forehead of the patient and the occlude base plate or the filter assembly is affixer to the front of headgear similar to an industrial eye protection googles.
A method claim to explain the procedure of testing for central loss of vision consisting of utilization of the special four part, all over pattern Diagram 100 eye chart and the delimiter arm to focus the vision on a small segment of the chart and causing the subject to establish the smallest letter that can be seen inside the bulls eye ring and then removing the bulls eye ring from the face of the chart and having the subject look all over the chart and try to see the lowest number that can be seen using side or peripheral vision and noting the acuity readings for the central vision versus the side or peripheral vision in the form of, for example, 20/60 central and 20/30 side and combining these two numbers into an index representing the denominators in the form 60/30 or an index of 2 wherein an index above 1 is suggestive of central vision loss.
