Our Research and Education in Ptosis. 15 In the automated, static perimeter, the test. 1. Some of these methods are simple compared to more. rhodopsin) of these cells are stimulated to propagate second messenger responses which convert light energy into electrical. Visual fields are usually assessed using the confrontation method; where the patient sits about 1 meter away from and immediately in front of the clinician. The eyelid skin must be resting on or in front of the patient’s eyelids causing a significant restriction of their peripheral visual field (side vision).

This distance also can be measured with the marginal reflex distance (MRD) test. Ophthalmologists also use visual field tests to assess how vision may be limited by eyelid problems such as ptosis and droopy eyelids. Cases of congenital ptosis can be caused by a lack of development in the muscles that control eyelid position and movement — and, specifically, the superior tarsal muscle (also called Muller’s muscle). When the visual field has been mapped out on a perimeter, the following notations should be made: (1) the size of the test object, which can vary from 1 to 25 mm, (2) the test distance, which is always 330 mm in a perimeter, (3) the color of the test object, and (4) the cooperation.
