“…This agrees with other hospital based studies as well as school eye health surveys that have also reported it as either the commonest [8,9,[14][15][16] or the second most common [2,7,10] cause of eye disease in children. Conjunctivitis was significantly higher in females (p=0.008).…”

“…This agrees with the previous clinical studies in Nigeria, which show that myopia is the most common refractive cause of visual impairment [3,5]. However, Ayanniyi et al [13,14] in a private optometry practice in AdoEkiti Nigeria and Bagaiya and Pam [16] in Kaduna State North Central Nigeria among University community both found hyperopia to be the commonest refractive error.…”

Purpose: The aim of the study was to determine the pattern of ocular conditions among patients who attended the Salvation Army Eye Clinic at Wiamoase in the Ashanti Region of Ghana in 2016.Method: A retrospective study of all patients attending the Salvation Army eye clinic at Wiamoase in 2016 was done.Results: A total of 1000 folders were used in the study. There were 382 males (38.20%) and 618 females (61.80%) with a male to female ratio of 1:1.6. The mean age was 45.99 years (SD= ± 27.69). The commonest eye disorder encountered was conjunctivitis (39.70%). This was followed by cataract (24.40%), glaucoma (9.70%) and refractive errors (8.90%). 96.72% of cases of cataract and 85.57% of cases of glaucoma occurred in those above 40 years. Of those with refractive error, there were 40.45% with myopia, 34.83% with astigmatism and 24.72% with hyperopia. Conjunctivitis and cataract were significantly higher in females with p values of 0.008 and 0.000 respectively using the chi square test. However, there was no significant difference in the prevalence of glaucoma and refractive errors between males and females with p values of 0.189 and 0.255 respectively. Presbyopia was significantly higher in males with p values of 0.017. Conclusion:Conjunctivitis, cataract, glaucoma and refractive errors were the major ocular conditions seen in this study. Efforts aimed at reducing ocular morbidity should target these conditions.

“…All pupils with significant refractive errors were myopic (Wedner & Foster, 2000). The results are consistent with the fi ndings elsewhere (Ajaiyeoba et al, 2007). In a previous study in north-western Tanzania a low (1.0%) prevalence of refractive error was reported (Wedner & Foster, 2000).…”

“…In adults (>15 years) myopia rose to 19.3%, hyperopia fell to 9.8%, and astigmatism was detected in 12.9% (Dandona et al, 2002). Like in our study, a higher prevalence of ocular disorders in females than males has also been reported in Nigeria (Ajaiyeoba et al, 2006).…”

Low vision is a major cause of morbidity and has profound effects on the quality of life for many people as it inhibits/reduces mobility and economical well being of the affected individuals and their families. The objective of the study was to determine the magnitude and causes of low vision among primary school children in Kibaha district in Tanzania. Primary schoolchildren were recruited for the study. The inclusion criterion was individual child with low vision of less than 6/18. Visual examination was used for screening the children to identify those with vision less than 6/18. Snellen's chart was used to measure visual acuity of the children with low vision. A total of 400 (6-17 years) schoolchildren were screened. Thirty-eight (9.5%) had low vision. The prevalence of low vision was statistically higher (N=33; 87%) among 12-17years old than among 6-11 years old (13%) (P<0.05). Of the 38 children with low vision, the prevalence in females (68%) was statistically higher than in males (32%). There were multiples causes of low vision among affected children. Congenital anomalies accounted for the largest proportion (65%) of the causes of low vision. In twenty-three (60%) of the children (12-17 years), low vision was due to retinopathies. Fifty-five percent of the children with refractive error were aged between 6-11 years. Among the cases, 8 (54%) had low vision caused by uncorrected refractive errors while the rest (46%) were due to other types of refractive errors. Two children had corneal scars; one with central and another with whole corneal scar. In conclusion, prevalence of low vision among schoolchildren in Kibaha district is high and increases with age. The main causes are congenital anomalies. There is need for an early detection of the possible causes and appropriate treatment to reduce the condition among schoolchildren. It is therefore important that the district Council Health Management Team establishes school eye screening programme for early detection and treatment. It is equally important to strengthen advocacy programme targeting schoolchildren, teachers and caregivers on the public health importance of low vision.
