Effect of malaria on Near Point of Convergence (NPC) and amplitude of accommodation


UzoDike, E. B. and Ndukwe, E. K

Malaria, a protozoan parasite caused disease is wid e spread in tropical and sub-tropical regions and i s more endemic in developing countries. The effect of malaria on near point of accommodation (NPC) and amplitude of accommodation (AA) were investigated o n 100 volunteer patients of First Rivers Hospital aged between 9-38 (mean age 24.73±2.91) years. NPC and AA tests were carried out on the patients on diagnosis of malaria through laboratory results, si gns and symptoms. The tests were repeated on recovery from the disease through the afore-mention criteria. Three values were taken for each visual function tested and the mean used for analysis. The mean NPC during malaria attack was 12.59±3.21cm and 9.51±3.21cm after recovery showing 32.39% reces sion in NPC during the attack. The mean AA during malaria attack was 8.78±3.53D and 11.05±3.53 D after recovery showing 20.54% reduction in AA during the disease. The percentage recession in NPC decreased with age while percentage reduction in AA increased with age. The observed effects were st atistically significant both with the different age groups and overall results (p<0.05).
