A survey is presented of orthoptic exercises practiced over the last 120 years. An attempt is made to deduce attitudes to the exercises from contemporary sensory theories. The currently prevalent nihilistic attitude toward orthoptic training is discussed.
In 67 unilateral aphakic patients corrected with three different optic systems (conventional contact lens, spheric overcorrection and intraocular lens) aniseikonia and binocular vision are tested. Conventional contact lens leads to 7% aniseikonia and to fusion in only half of the cases. Patients with the two other systems show less than 3% aniseikonia and fusion in most cases. With each system only 10% of the patients reach normal stereoscopic vision. The poor results in unilateral aphakia corrected by conventional contact lens are pointed out.

A report is given on a test-instrument which enables us to check the following functions: 1. Visual acuity (Line-E-acuity), 2. Binocular vision by Worth-4-dot-test, 3. Optical correction by Red-Green-test. 4. Stereoacuity by Polaroid-test.
