Spectacle design preferences among school children in Enugu State, Nigeria.

BACKGROUND: Uncorrected refractive error has profound effects on children's educational and social development and spectacles are cost-effective in correcting this. However, the cosmetic appearance of spectacles may affect compliance to prescribed spectacles. AIMS: This study explored spectacle design preferences of school children in Enugu State, Nigeria and any associated sociodemographic factors. A cross-sectional study among children aged 5-15 years from schools in Enugu state, Nigeria. PATIENTS AND METHODS: The children independently selected from sets of spectacle frames, indicating their preferences on the basis of spectacle frame color, material, shape and size of the lens portion, design of the earpiece portions. Simple descriptive analysis was performed. Frequency tables were generated. Pearson's Chi-square test was used to test associations between categorical variables. Odds ratios were used to measure the strength of the associations where P < 0.05. Tests of significance were set at the 95% level. RESULTS: A total of 1,167 children (45.6% male and 54.4% female) were seen. Majority of the children preferred red colored spectacle frames 467 (40%), plastic frames 723 (62%), rectangular shaped lens-pieces (55.2%), and frames with a straight earpiece 987 (84.6%). There is a strong association between gender and choice of spectacle colour (P < 0.01), gender and lens size preference (P < 0.05), and between school location and shapes of spectacle earpiece (P < 0.01). CONCLUSIONS: Spectacle preferences exist among the study population and some demographic factors are associated with these preferences which should be considered in any childhood refractive error services.

Prevalence of refractive errors and visual impairment in school children in Enugu South-East Nigeria.

AIMS: To determine the prevalence of refractive errors and causes of visual impairment in school children in Enugu State, South-eastern Nigeria. METHODS: A descriptive cross-sectional, school-based survey in children aged 5-15 years from selected primary and junior secondary schools (public and private) in both urban and rural communities of Enugu State was carried out. Ocular examinations were performed on them according to the Refractive Error in School-age Children (RESC) protocol. RESULTS: A total of 1167 children were examined. The mean age (standard deviation) was 10.58 ± 3.0 years. Females were 653 (54.4%) of the study population. The uncorrected, presenting and best-corrected visual acuity of ≤20/40 (6/12) in the better eye of the children in this study were 3.6%. 3.5% and 0.4%. Among the children that had visual impairment, refractive error accounted for 33.3% of reduced vision while the overall prevalence of refractive error was 2.1%. Prevalence of myopia was 1.9% and hyperopia, 0.1%. The most prevalent astigmatism was ≤0.75 dioptre cylinder. CONCLUSION: The prevalence of refractive error in this study is low, with myopia being more common. Despite the low prevalence of refractive error, school vision screening is still important for African children as it serves as an opportunity to identify other ocular morbidities among the children.

Audit of ophthalmology discharge summaries in a Nigerian Teaching Hospital.

BACKGROUND: Discharge summaries are important components of hospital-care transitions in ensuring continuity of care. AIM: We assessed the adequacy and accuracy of discharge summaries written by junior doctors. METHODS: An instrument, adapted largely from the current hospital discharge summary template and recommendations regarding content from the Joint Commission International, was used to study 420 discharge summaries written in 2012 from the ophthalmology service of a Rural Teaching Hospital in Nigeria. The simple descriptive analysis was done with Statistical Package for the Social Science version 17. RESULTS: Completeness of entries was relatively high in many traditional areas (biodata of patient, admission/discharge dates, name of supervising consultant, principal diagnosis, surgical procedures done, follow-up instructions, and condition on discharge) of the summaries. The portion of the paper-based template titled "summary" of the admission was most problematic; with information on medication changes and result of tests missing in 368/420 (87.6%) and 334/420 (79.5%), respectively. CONCLUSION: Educational intervention for doctors in training with the provision of oversight and feedback by their supervisors is required. Standardized discharge summary templates recognizing the peculiarities of specialized patient groups are recommended. Transition to electronic discharge summary system is imperative.

Short term results of pterygium surgery with adjunctive amniotic membrane graft.

OBJECTIVE: The objective of this study is to present the 3 months results of pterygium excision with adjunctive amniotic membrane graft. MATERIALS AND METHODS: In a non-comparative case series study, the medical records of all patients who had pterygium excision with adjunctive amniotic membrane transplant on bare sclera from December 2009 to August 2010 were reviewed. All the patients were followed up for 3 months. The data collected were sex, age, occupation, type of pterygium (primary or recurrent), extent of pterygium, post-operative complications and recurrent pterygium growth. RESULTS: Thirty eyes of 30 consecutive patients were operated on. There were 14 males and 16 females (M:F =1:1); age range 25 to 70 years (mean: 48.3 SD + 12.01). Twenty-six eyes had primary and 4 recurrent pterygia. Stage 3 pterygium accounted for most of the cases (53.3%) followed by stage 2 (36.7%) and stage 4 (10%). Nineteen patients (63.3%) had occupations with considerable exposure to actinic damage. Of these, manual laborers accounted for the highest number contributing 13 (43.3%) out of the 19 cases. Of the 30 patients 2 had a reoccurrence giving a recurrence rate of 6%. One patient developed dellen 1 week post-operatively with complete resolution following conservative large soft contact lens application. CONCLUSION: Short term results suggests that adjunctive amniotic membrane transplant with pterygium excision is effective and safe. A larger randomized clinical trial with a longer follow-up period is however recommended.
