if you can perform Albino-VEP, do this. What does the child look like? if she origins from your country, she might be a bit paler than the family in albinism, not necessarily white.
Is there delayed visual maturation DVM? this is a very frequent symptom in albinism, more than in other congenital visual impairments.
Are the parents related? any positive FH for nystagmus, Low vision?
Management:
prescribe glasses, 20% and 80% tint for inside/outside respectively
affirm parents that visual abilities will definitely improve (especially if the child has DVM)
once the child starts fixating, start alternating patching of 30mins per day per eye - this helps visual development of each eye and may reduce the (high) risk of developing strabismus
genetic analysis can be done, but is less reliable than a good clinical analysis, as many albinists (approx. 25%) do not show alterations in the up to now known genes. In addition, genetic analysis does not help to foresee the possible visual development.
If available in your country, start the child with early visual intervention programm.
Alternatively, give the patients the following link which includes many informations for early visual intervention (in many languages): www.lea-test.fi
