[Amplitude of accommodation in Zairian subjects].
The authors studied the amplitude of accommodation in Zairian patients who consulted the Ophthalmic Clinic of University of Kinshasa from February 24 to July 31, 1986. During this period, of 1326 Zairians seen, 159 (318 eyes) were included in this study. Patients with monocular visual acuities less than 10/10, or with ocular pathology, astigmatisms and anisometropias exceeding one diopter were excluded from the study. The mean age +/- SD was 32 years +/- 12 with a range of 10 to 58 years. There were 101 males and 58 females. The measurements were performed, once for each patient, with Osterberg Bino-Oculus apparatus according to the "push-up" method and the plus spherical method. The amplitude of accommodation decreased with the age. This decrease was more notable between 30 and 40 years. The age of onset of presbyopia calculated from the amplitude of accommodation according to the "push-up" method was 39 years. The values of the amplitude of accommodation obtained by the both methods could be superposed (p greater than 0.05). They were similar to those of black patients and were also inferior to the white patients obtained by other authors.
