Burden of family caregivers of ophthalmic patients in a university teaching hospital in south-west Nigeria.

Background: The family provides support in the care of their ill members and suffers some burden during caregiving. This study assessed the burden of family caregivers and associated factors in an ophthalmic clinic situated in a university teaching hospital in southwest Nigeria. Methods: This was a descriptive cross-sectional study where consenting family caregivers of ophthalmic patients completed a semi-structured questionnaire containing information on their socio-demographic characteristics and caregiving burden using the Zarit burden interview. Descriptive and inferential statistics analyses were done. Results: A total of 273 caregivers completed the study. The caregivers were parents (23.5%), spouses (20.1%), siblings (3.3%), children (35.9%) and other relatives (14.2%) with mean age (SD) of 38.9 (14.9) years (range 8-79 years). Majority (81.2%) experienced caregiver burden with prayer (89%) as a coping strategy. Financial support (56%) was a major caregiver need with majority (59.3%) satisfied with their relatives' hospital care. Neither the patients nor their caregivers were on health insurance scheme. Statistical significant factors associated with caregivers' burden included young age (AOR=4.63, 95%CI=1.55-13.90; p=0.01), higher education (AOR=5.51, 95%CI=2.30-13.2, p=0.01), being employed (AOR=1.72, 95CI=1.30-4.76, p=0.04), longer caregiving (AOR=3.37, 95%CI=1.27-7.02, p=0.02), and having patient on hospital admission (AOR=1.90, 95%CI=1.26-3.09, p=0.02). Conclusion: Family caregivers of ophthalmic patients experienced significant burden. Hence, they need more assistance from the health care institutions and community, including policy makers, so that they can cope with their caregiving activities. Enrollment in the social health insurance scheme will reduce out of pocket payment of hospital bills.

Effects of fasting on intraocular pressure in a black population.

INTRODUCTION: There is a dearth of literature available on the effects of fasting on Intraocular pressure (IOP) among all races and worldwide. OBJECTIVES: To determine the effects of fasting on IOP in a black African population. MATERIALS AND METHODS: A population-based survey utilizing multistage random sampling techniques was carried out among healthy adult Muslims who were examined before and during Ramadan fast in Osogbo, Nigeria. Demographics were obtained, visual acuities, clinical examination of both eyes, and IOPs were done. Weights and waist circumference were measured. Data were analyzed using Statistical Package for Social Sciences ( SPSS) Version 16. Analysis generated frequencies and cross tabulations, whereas statistical significant values were derived using paired sample t-test and P < 0.05. RESULTS: A total of 60 subjects with 120 eyes were examined. Mean age was 42.3 years standard deviation (SD) 16.7, and the male to female ratio was 3:2. Majority were professionals (33.3%). Only 18.3% had less than secondary school education. Over 90% had normal vision (6/5-6/18). Before and during fasting, the mean weights were 65.92 kg SD 12.98 and 65.29 kg SD 12.41 with a reduction of 0.63 kg SD 3.82 (P = 0.214, 95% confidence interval (CI): 0.372-1.626); and the mean waist circumference was 87.20 cm SD 12.39 and 81.78 cm SD 11.65 (P = 0.000, 95% CI 4.128-6.720), respectively. Mean IOPs were 15.98 mmHg SD 3.11 and 14.08 mmHg SD 2.71 before and during fasting, respectively (P = 0.000, 95% CI 0.98558-2.82798). CONCLUSIONS: The study shows that fasting significantly reduced IOP in an ocularly healthy black African population.

Honeybee sting of the sclera: occular features, treatment, outcome and presumed pathogenesis.

Ocular bee sting injury has caused several reactions in the eye but has rarely been reported among local African farmers, and Nigerians in particular. This case seeks to report the first ocular and external eye reactions following a honey bee sting of the eye through the sclera, highlighting the treatment and outcome. Oral interview, clinical examination and external photographs were used to obtain and document findings. Medical treatment was instituted as soon as subject presented. There was complete inflammatory resolution within a week, normal vision and no evidence of stinger migration after four weeks of follow up. The wound site healed with ciliary staphyloma. The role of physical properties, immunological and genetics interplay and the presumed pathogenesis is further discussed. Health education on early presentation and avoidance of harmful traditional eye medications should be promoted among the farming populations in our communities, in order to prevent blinding complications.

Awareness of and Attitude towards glaucoma among an adult rural population of Osun State, Southwest Nigeria.

PURPOSE: To obtain baseline data and assess the level of awareness and attitudes towards glaucoma among rural communities of Osun State, Nigeria. MATERIALS AND METHODS: This was a community-based study that involved interviews and descriptive cross-sectional analysis. Serial-recruitment was performed of consenting participants who presented at a community-based screening service in March 2011. Socio-demographic data and information about glaucoma were obtained through face-to-face semi-structured questionnaires. RESULTS: The study population comprised 259 respondents (mean age 49.73 ± 16.6 years; range 18 to 90 years). There were 159 females (61.4%). Skilled workers were the most common 130/259 (50.3%) participants. Only 41 (15.8%; 95% CI: 11.4-20.2) participants had ever heard of glaucoma. Sources of information were from visits to an eye clinic for 21/41 (51.2%; 95% CI: 35.9-66.5) participants and 15/41 (36.6%) participants who know someone with glaucoma. Reponses to the causes of glaucoma included 20/41 (48.8%; 33.5-64.1) participant who said 'I don't know' and 24.4% of participants who responded 'curse-from-God'. Responses to questions on treatment included 20/41 (48.8%) participants who responded 'I don't know how it can be treated' and 10/41 (36.6%) said 'medically'. Thirty 30/41 (73.2%) participants would refuse surgery, half of them because 'it cannot cure or reverse the disease' while (26.7%) would refuse out of 'fear'. Only 8/41 (19.5%; 95% CI: 7.4-31.6) would accept surgery for maintenance. Statistically significant predictors of glaucoma awareness were older participants, males and skilled workers (teachers) (P = 0.028, P = 0.018, P = 0.0001, respectively). CONCLUSIONS: The outcomes of study indicate a low level of awareness of glaucoma. Health education at all levels of health and eye care services is required to prevent ocular morbidity and irreversible blindness from glaucoma.

The dangers of couching in southwest Nigeria.

The need to highlight the dangers to the eye and visual status in couching has become necessary in order to discourage its patronage. This was a bi-center clinic-based prospective descriptive study about new cases of couched eyes which were seen over a two-year period. Oral interviews, eye examinations, refractions, and perimetry tests were used to obtain the information. SPSS version 16 was used for the descriptive analysis. Twenty-five patients and 30 eyes of 15 (60%) males and 10 (40%) females were studied. The age range was 34-90 years with a mean age of 67.87 years (SD 11.27). Presenting versus (vs) corrected visual acuity (VA) for normal vision was 6.7% vs 23.3%, visual impairment was 16.7% vs 26.3%, and blindness was 76.7% vs 50%. A significant number still remained blind after corrections (P = 0.014). The most common presenting complaint was "poor/blurred vision" in 24 (80.4%) and the most frequent duration of couching before presentation was 7-12 months (46.7%). Subjects with a cup:disc ratio > 0.6 had intraocular pressures (IOPs) of > 21 mmHg, and 50% of those patients had IOP > 40 mmHg (P = 0.001). Glaucoma (13.3%) and corneal opacity/retinal detachment/couching maculopathy/optic atrophy (10%) were the most common complications. Couching causes visually-disabling complications, and is therefore strongly condemned. Increasing public awareness and putting a policy in place for affordable and accessible cataract services in government hospitals would gradually phase out its patronage.
