The visual acuity is variable but almost always reduced. We report on two brothers with oculocutaneous albinism and markedly different visual acuity. One brother has a visual acuity of 20\/100, while the second has similar cutaneous pigmentation and visual acuity of 20\/20 and had not previously been recognized as having oculocutaneous albinism. Both brothers have foveal hypoplasia and misrouting of the optic fibers at the chiasm. Biochemical analysis suggests that this is a tyrosinase\u2010related type of oculocutaneous albinism, This study demonstrates that careful observation of foveal development in relatives with normal vision is necessary to detect all individuals with albinism in a family. A suspected diagnosis of albinism may be confirmed when the visual\u2010evoked potentials show excessive decussation of the optic fibers at the chiasm.<\/jats:p>","DOI":"10.1002\/ajmg.1320400316","type":"journal-article","created":{"date-parts":[[2005,6,12]],"date-time":"2005-06-12T04:24:13Z","timestamp":1118550253000},"page":"327-331","source":"Crossref","is-referenced-by-count":28,"title":["Variable expression of vision in sibs with albinism"],"prefix":"10.1002","volume":"40","author":[{"given":"C.
