Multiple Choice

Type 2 oculocutaneous albinism is associated with which visual acuity range?

Oculocutaneous albinism type 2 reduces pigment in the eyes, which interferes with the development and function of the retina, especially the fovea, leading to reduced central vision. This structural impact produces a characteristic pattern of visual acuity that is clearly worse than normal but not uniformly catastrophic. The typical range seen with this condition is around 20/100 to 20/200, reflecting a substantial but variable decrease in sharpness of vision that many individuals with this type experience. Other ranges like 20/20 to 20/40 would indicate near-normal vision and aren’t consistent with the common effect of this condition, while 20/200 to 20/400 can occur in more severe cases but is less representative of the usual presentation. The option mentioning no pigment doesn’t describe acuity at all, so the 20/100–20/200 range best fits the pattern seen in Type 2 OCA.
