  • steady
  • Additional tests/procedures included laser interferometry which demonstrated maximal visual acuity of 20/30, cover testing which revealed five prism diopters of exophoria at distance and 10 prism diopters of exophoria at distance, stereo testing which demonstrated 50 seconds of contour stereo at 16 inches with the presence of global stereo and visuoscopy which demonstrated steady bifoveal central fixation.

  • genetic
  • Ocular albinism (OA) is characterized as a group of genetic disorders presenting with reduced pigmentation of the eye in association with variable degrees of decreased visual acuity, nystagmus, strabismus and photophobia, in the setting where pigmentation of skin and hair is relatively normal.
