Iris transillumination in albinism
A patient with oculocutaneous albinism with white eyebrows and lashes.
The patient may have oculocutaneous albinism or ocular albinism. The former should be easy to detect because the patient
has blond hair and white eyebrows and lashes. In the examination, the request may be examination of the anterior segment
or ocular motility (convergent strabismus and nystagmus are common in albinism).
The patient has blond hair and poliosis. There may be obvious nystagmus (usually pendular) and convergent strabismus.
The iris shows transillumination.
- Fundal examination may reveal macular hypoplasia (shown by absent foveal reflex and failure of the retinal vasculature
to wreathe the fovea). The retina is hypopigmented making the choroidal vasculature easily visible.
