Routine aniseikonic screening.
Analysis is made from data obtained after screening 1,000 measurable cases attending the eye department of a general hospital consecutively. Some 9 per cent of these patients were found to have a significant degree of aniseikonia. Symptoms of aniseikonia were found to be less common than suggested in the literature; these are limited to 3.6 per cent of the patients surveyed and are absent where the degree of aniseikonia is less than 2 per cent. It is concluded that since the number of patients having a significant degree of aniseikonia is as great as 9 per cent and that the empirical estimation of aniseikonia is unreliable, it is desirable to include eikonometry into the clinical refraction routine.
