||A neurological, ophthalmological and audiological survey of a suburban Jamaican community|
||West Indian med. j;16(4):233-45, Dec. 1967.
||A neurological, opthalmological and audiological survey was conducted in a suburban Jamaican community aged 35-74 years. One aim was to determine the prevalence of signs found in the Jamaican neuropathy syndrome and their association with sensorineural hearing loss and retrobulbar neuropathy. Mean hearing levels of Jamaicans were better than those reported from a comparable Scottish population. Conductive hearing losses, including otosclerosis, were uncommon. Sensorineural loss was found in 5.0 percent of men and 11.4 percent of women; presbyacusis was a possible cause in older subjects but in many the aetiology was unknown. Noise-induced hearing loss was not an important cause of impaired hearing. Refractive errors in vision were common and many needed proper correction. Pterygia were common (15.9 percent) but less prevalent among those of predominantly African origin, suggesting a racial difference in susceptibility. The prevalence of progressive cataract rose from 3.2 percent at 35-44 years to 71.7 percent at 65-74 years and was greater in diabetics than non-diabetics. Eight cases of chronic simple glaucoma were detected, a prevalence greater than that reported in a Welsh population. Tropical amblyopia (poor visual acuity, temporal pallor and field defects) was found in eight cases. Unexplained neurological signs, possibly representing manifestations of the Jamaican neuropathy syndrome, were found in 25 subjects (4.8 percent of females and 4.0 percent of males). Sensorineural hearing losses and retrobular neuropathy were common in these than in normal subjects but also occurred separately; it is unknown to what extent they are due to the same aetiology (AU)|
