A study of ophthalmic patients at Harari Hospital indicates that Rhodesian Blacks in Mashonaland constitute a population with interesting ophthalmic features. There is a low incidence of refractive error, with a total incidence of 8,5% of myopia in adults. Functional concomitant squint is uncommon, with an incidence of 0,8% in children under 15 years of age. Non-traumatic, idiopathic primary retinal detachments occur rarely, while secondary retinal detachments occur with low frequency (about 0,55 per 100 000 population per year). Acute and painful congestive angle closure glaucoma is not seen, although chronic angle closure glaucoma is sometimes encountered. Hypertensive retinopathy is not infrequently seen, while diabetic retinopathy is uncommon. Visual loss and blindness from corneal disease are wide-spread. The population has a remarkably low incidence of senile macular degeneration (1,13% of adults over 65 years of age).
对哈拉里医院眼科患者的一项研究表明，马绍纳兰的罗德西亚黑人构成了一个具有有趣眼科特征的人群。屈光不正的发病率较低，成年人近视的总发病率为8.5%。功能性共同性斜视并不常见，15岁以下儿童的发病率为0.8%。非创伤性、特发性原发性视网膜脱离很少发生，而继发性视网膜脱离的发生率较低（每年每10万人中约有0.55例）。虽然有时会遇到慢性闭角型青光眼，但未见急性疼痛性充血性闭角型青光眼。高血压性视网膜病变并不少见，而糖尿病性视网膜病变则不常见。角膜疾病导致的视力丧失和失明很普遍。该人群老年性黄斑变性的发病率极低（65岁以上成年人中为1.13%）。
