Cataract surgical coverage and barriers to uptake of cataract surgery in leprosy villages of north eastern Nigeria.

AIMS: To determine the coverage, outcome, and barriers to uptake of cataract surgery in leprosy villages of north eastern Nigeria. METHODS: People 30 years and above resident in eight leprosy villages were examined. Cataract blind people were questioned about the reasons they had not been treated. Subjects who had received an operation for cataract were examined to determine the outcome and, where applicable, the causes of poor outcome. RESULTS: 480 people were examined. Cataract was the commonest cause of blindness. The cataract surgical coverage (people) was 39.2% for orthodox surgery and 29.7% for couching. After surgery, visual acuity > or =3/60 had been restored to 82.1% of eyes that had had orthodox surgery, but only 58.6% of eyes that had been couched. Cost was the commonest reason given for not seeking treatment for cataract. CONCLUSIONS: Cataract is the major cause of blindness in this population but cataract surgical needs are currently not being met. There is a need for better collaboration between leprosy control and ophthalmic services, improved education of people affected by leprosy, a commitment to improving orthodox cataract surgery outcomes, and consideration of a possible role for traditional healers as sources of referral for orthodox surgical services.

The pattern of cataract and the postoperative outcome of cataract extraction in Ethiopian leprosy patients as compared to nonleprosy patients.

Cataract is a blinding disease occurring all over the world. One of the causes of cataract is leprosy. Sixty leprosy and 100 nonleprosy patients were assessed and underwent intracapsular cataract extraction. Leprosy patients with cataract were much younger than nonleprosy patients. The leprosy group had a significantly higher rate of complications and this was seen more in paucibacillary cases. There was a higher rate of visual disability in the leprosy group than in the nonleprosy group. Cataract was seen in younger patients in the leprosy group. This raised the possibility of leprosy being the cause of the cataract. The leprosy group consisted mostly of multibacillary cases, however unlike in other studies the rate of complications tended to be higher in the paucibacillary group. There were no preoperative findings that correlated with a low postoperative intraocular pressure.
