Functional visual loss in Cambodian refugees: a study of cultural factors in ophthalmology.

South East (SE) Asians accounted for a disproportionate percentage of the functional visual loss (FVL) seen in our area between 1983 and 1987. Moreover, 94% of the SE Asian FVL patients were Cambodian, although Cambodians only represented 20-30% of the local SE Asian patient population. Cambodian refugees are, at present, generally from lower socio-economic classes than the Vietnamese, and a much larger percentage of them have a history of camp incarceration and previous trauma. The Cambodians presenting with FVL may have conversion hysteria influenced by their wartime experience and cultural background. This study demonstrates that the SE Asian refugees in California are not a homogenous group with respect to visual problems, and that an awareness of cultural or historical factors can be important to the management of ophthalmic symptoms in our multi-cultural societies.
