There are no studies available to describe the epidemiology and causes of low vision in Nigeria and Africa. A retrospective record review was conducted of low vision patients seen at the 2-weeks-per-month low vision clinic carried out at ECWA Eye hospital, Kano, by the Low Vision Programme between the periods 1999 to 2004. Records of 1200 patients, age range, 4 month – 92 years seen within the period were reviewed. 70.3% were males, 11.3% were between age range 4 months-14 years; 73.2%, 15-65yrs; 12.8%; 65 yrs and above. The major causes of low vision are glaucoma, 19.8%; followed by aphakia/inoperable cataract 28.9% and maculopathy8.8%. The majority of the patients (34%)had their best-corrected Visual Acuity in the range of <6/18 – 6/60. 1515 optical aids were prescribed. 40.1% were refractive corrections, 36.4% magnifiers while 23.4% were telescopes. 88.3% of the patients seen were advised to cope with their education/employment. 7.6% were referred for Braille lessons. Information on characteristics of the Nigerian low vision population would help in policy formulation and funds allocation for low vision rehabilitation particularly in developing countries.
