ABSTRACT:
A new and improved slit lamp microscope table with a front recess of suitable size to accommodate the torso of the occupant of a wheel chair or an obese individual. With the table set at an appropriate elevation, the handicapped individual can move his or her wheel chair to the vicinity of the table. The wheel chair is rolled toward the table until the user is located with his or her torso in the recess. Once the patient is in position, the table can be lowered to the point at which the arm rests of the table come into contact with the arms on the wheel chair and more positively hold the table and wheel chair in the desired relation.
