contribution and increase treatment of Mental Disorder, and level of Individual capability, in childrens, and illiterate people, and early diagnosis Mental retardation, Downs’s syndrome, Turner syndrome, Klinefelters syndrome.

70 normal subjects male and female school and university students of different ages were studied, the measurement of interpupillary distance (IPD), in normal individuals with no refractive error and strabismus, through the utilization of Thompson refract meter 2002, and gauge ruler, special research device and computerized study on papillary reflex (Fig.1).3D imaging as well as Wechsler and Godinoff tests were applied for intelligence scoring. And 1500 interpupillary distance only having been measured without IQ tests.

Through conducting research on ocular anatomy, human Brains function, accurate relation between the papillary and ocular muscles and macula and wrenickes area (Fig. 2) and also IPD, and conditional rods(Fig .3),synapse between vision neurons(Fig. 4), we compare the results between (IPD) and (IQ) and rate of accommodation in the each case.

Management of Mental Disorder, and level of Individual capability, in children’s, and illiterate people, and early diagnosis Mental retardation, Downs’s syndrome, Turner syndrome, Klinefelters syndrome. With relationship between the intraocular or Interpupillary visual axis (IPD) distances, with level of intelligence personal dated (IQ).
