<prompt> Obstacles in concomitant squint type is:Motor obstaclesSensory obstaclesCentral obstaclesAll of the above  <response>: CONCOMITANT SQUINT - type of manifest squint in which the amount of detion in the squinting eye remains constant in all directions of gaze, no limitation of ocular movements.. Any obstacles to the development of these processes result in concomitant squint . 1 Sensory obstacles -hinder the formation of a clear image in one eye. E.g. Refractive errorsProlonged use of incorrect spectaclesAnisometropiaMedia opacities - CornealLenticular opacities 2 motor obstacles - hinder the maintenance of eyes in the correct positional relationship in primary gaze or during ocular movements . E.g. - Congenital abnormalities of shapesize of the orbitAbnormalities of extraocular muscles 3 central obstacles -Deficient development of fusion facultyAbnormalities of coical control of ocular movements as occurs in mental Trauma and hyperexcitability of CNS during teething.
