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.

Other examination:


1. How is albinism inherited?

2. Can one predict the severity of visual impairment in a child with oculocutaneous albinism?

3. How can visual evoked potential be used to diagnose albinism?

4. Do patients with albinism have normal life expectancy?
