Eye Care Seeking Behaviours of Patients in Rural Cross River State, Nigeria

The major causes of blindness in Cross River State, Nigeria are refractive error, glaucoma and cataract. The World Health Organization had estimated that about 145 million people have significant distance refractive errors and at least 13 million of these were children. About 80% of these causes of blindness are avoidable at the primary level of care. The aim of this study was to determine factors responsible for the eye care seeking behaviour of patients in three rural communities of Cross River State, Nigeria. A 39-item structured questionnaire was used to interview 290 patients who visited selected primary health centers (PHC). Most patients, 40.7% were 20 – 29 years and 44% walked to the center. Reasons for clinic visit included, fever, 44.5%; immunization, 30.7%; antenatal care, 13.1%; and eye care, 4.5%. About 51% had a history of eye problems, of these; only 29.7% visited a hospital while 42% visited either a patent medicine vendor or traditional healers. About 49% had family history of spectacle use, of these; 34.5% got glasses from lay eyeglass sellers, 33.8% from hospital/eye clinic, 25.4% from outreach eye screening, and only 4.2% from PHC. Due to reported unavailability of eye care services at the PHC, patients tend to use available albeit questionable eye care services closest to them before visiting secondary health facilities when symptoms persist. The PHC’s proximity to the patients may likely increase access to blindness prevention services if made available at the primary care level.

Comparative Analysis of Satisfaction with the Use of Ready-Made Spectacles and Custom-Made Spectacles among School Children in Nigeria: A Randomised Controlled Trial

Refractive error is an important cause of visual impairment in Cross River State (CRS), Nigeria. Optical services and spectacles are not readily available to school children for the treatment. The aim of this study was to compare satisfaction with the use of ready-made spectacles and custom-made spectacles in the treatment of refractive error for school eye health programme. A one month double-blinded randomised controlled trial was used to evaluate satisfaction, symptoms, vision and planned continued use of ready-made and custom-made spectacles in school children 6 -17 years with ≥ 1 diopter of uncorrected refractive error. The sample size for each arm was 63. This research was funded by African Vision Research Institute (AVRI). Full ethical approval was obtained from the ethics committee CRS Ministry of Health, Nigeria. Data was analysed using SPSS and EPI info. Out of the 2110 children refracted with non-cycloplegic method, 243 (11.5%) has significant refractive error and only 104(82.5% response rate) met the inclusion criteria for the intervention study. There was no difference (p >0.05) in satisfaction (96.2% vs 96.2%) and  symptoms ( headache 5.8% vs7.7%; eye strain 3.8% vs 1.9%  ) in the use of ready-made vs custom-made spectacles to the 1 month follow up. Ready-made spectacles are recommended for eye health programmes in schools because it is a cost effective strategy for treatment of refractive errors. The ready-made spectacles should be available in different frame pupillary distance for various powers to reduce discomfort associated with frame induced prismatic effect.

Assessment of knowledge, practice and guidelines towards the novel COVID-19 among eye care practitioners in Nigeria : a survey-based study

The aim of this study was to explore knowledge, practice of risk and guidelines of the novel corona virus disease (COVID-19) infection among the eye care practitioners and the potential associated factors. A cross-sectional self-administered online survey was distributed via emails and social media networks between 2nd and 18th May 2020 corresponding to the week of the lockdown in Nigeria to eye care practitioners (ECPs). Data for 823 respondents were analyzed. Knowledge and risk practice were categorized as binary outcome and univariate and multivariate linear regression were used to examine the associated factors. The mean score for COVID-19-related knowledge of public health guidelines was high and varied across the ECPs. Ophthalmic Nurses, Ophthalmologists and Optometrists showed higher COVID-19-related knowledge than other ECPs (p < 0.001), particularly those working in the private sector. More than 50% of ECPs stated they provided essential services during the COVID-19 lockdown via physical consultation, particularly the Ophthalmologists. Most respondents reported that the guidelines provided by their Association were useful but expressed their lack of confidence in attending to patients during and after the COVID-19 lockdown. Compared to other ECPs in Nigeria, more Ophthalmic Nurses received training in the use of Personal Protective Equipment (PPE). This survey is the first to assess knowledge, attitudes and practice in response to the COVID-19 pandemic in Nigeria. ECPs in Nigeria displayed good knowledge about COVID-19 and provided eye care services during the COVID-19 lockdown in Nigeria, despite the majority not receiving any training on the use of PPEs with concerns over attending to patients. There is need for the government to strengthen health systems by improving and extending training on standard infection prevention and control measures to ECPs for effective control of the pandemic and in the future as essential health workers

Prevalence of Presbyopia, Spectacle Correction Coverage and Unmet Need, among Adults in Cross River State, Nigeria.

Purpose: To determine the prevalence of presbyopia, spectacle correction coverage and its unmet needs among adults 35 years and above in the study area.Methods: This cross-sectional descriptive study design used multistage cluster random sampling procedure to select the 616 adults. Data was collected using an interviewer administered semi-structured questionnaire. Visual acuity at distance and near was tested with Snellen’s chart at 6m and 40cm respectively. This was followed by eye examination. Presbyopia was defined as near visual acuity of N8 or worse. Relationship between variables were determined using chi square and multivariate analysis at 5% significant level.Results: The average age of participants was 48.1 years ± 10.4 (range, 35-88 years) and 330 (53.6 %) were males. The prevalence of presbyopia was 73.2% (95% Confidence interval [CI]: 69.5, 76.7). Multiple regression analysis showed that, female sex (Adjusted odds ratio [AOR] =1.58 (95% CI: 1.02, 2.38), older age (AOR =3.29 (95% CI: 1.02, 13.6), unemployment (β = 0.47, p = 0.016, AOR =1.59 (95% CI: 1.26, 4.55), lack of formal education (β = -3.67, p &lt; 0.001, AOR =0.03 (95% CI: 0.007, 0.09) were significantly associated with presbyopia. The spectacle correction coverage and unmet presbyopic need were 40.8%, and 59.2% respectively.Conclusion: The Prevalence of presbyopia and unmet presbyopic correction were high among the participants. This can be addressed through awareness creation and provision of accessible and affordable primary eye care services in the communities
