Abstract

Background: Health-seeking behavior is important as it reveals the preventive, curative, and rehabilitative actions taken by individuals to rectify perceived ill-health., Aim and Objectives: To identify existing eye health-seeking behavior, factors influencing such behavior, and suggest ways in which the system can respond to the needs of the target population in order to reduce visual impairment and blindness., Methods: This was a descriptive cross-sectional study; 600 respondents were interviewed using a semistructured pretested questionnaire administered to every fifth new patient attending the eye clinic of University of Calabar Teaching Hospital (UCTH) for a period of 5 months by a single interviewer. People unable to respond appropriately were interviewed alongside their caregivers., Results: Poor distant vision was the most frequent ocular complaint in this study. The mean duration of complaint before presentation to any health facility was 370.65 ± 889.48 days with a range of 0-9,125 days. Nature of eye complaint was the most significant factor that determined how early respondents sought help (P < 0.001). Place of residence, nature of eye complaint, and employment status were significant determinants of the choice of place of first presentation for ocular complaints., Conclusion: There is need for improved eye health education and awareness for prompt presentation to an appropriate eye care professional at the onset of symptoms and even case finding for potentially blinding eye conditions., Competing Interests: None

Abstract

To determine the trend in frequency and clinical indications of surgical removal of eyes in a tertiary eye centre in Calabar, Nigeria. This is a 10-year retrospective review of patients who underwent surgical removal of eyes in a tertiary centre. The clinical records were reviewed (between Jan 2001 and Dec 2010) for demographic data, type of surgery, and clinical indications. A total of 137 eyes were surgically removed within the study period. Of these 46 were children (<16 years). There were 85 males and 52 females giving a M:F ratio of 1.6:1. Clinical indications for surgical eye removal include infective causes (32.1 %; perforated corneal ulcers, endophthalmitis, panophthalmitis), trauma (21.2 %), tumours (21.2 %), anterior staphyloma (13.1 %), and painful blind eyes (9.5 %). Phthisis bulbi, expulsive haemorrhage and aphakic bullous keratopathy accounted for the remaining 2.8 %. The eyes were removed by evisceration (63.5 %), enucleation (29.9 %) and modified exenteration (6.6 %). The commonest indication for eye removal in children was tumour (retinoblastoma). Eye removal in southern Nigeria is often due to infective causes (panophthalmitis and endophthalmitis), perforated corneal ulcer, mechanical trauma (blunt or open globe injury from gunshots or direct trauma), chemical burns, tumours, persistently painful blind eye and anterior staphyloma. Other indications for eye removal were phthisis bulbi, expulsive haemorrhage and aphakic bullous keratopathy.

Ikeja, Lagos, NigeriaTel +234 8035027308Email o_okonkwo@yahoo.comPurpose: To determine the burden of retinal diseases and the degree of visual impairment associated with each disease, amongst Nigerians.Patients and Methods: This was a hospital-based multicenter, prospective, cross-sectional, non-comparative study conducted from January to December 2018. Data was obtained from consecutive patients with a retinal diagnosis presenting at the general ophthalmic and specialty retina clinics in four hospitals (three public, and one private teaching eye department) in Nigeria. Biodata, visual acuity and refraction, intraocular pressure, findings on dilated retinal examination, diagnosis and systemic diseases were noted. Degree of monocular and bilateral visual loss associated with each diagnosed retinal disease was summarized and p value was calculated using chi-square test. P < 0.05 was considered significant.Results: Eight hundred seventy-six of 8614 patients had a retinal diagnosis; establishing a hospital-based retinal disease prevalence of 9.8%. Male:female ratio was 1.1:1. The mean age of study patients was 49.97 (standard deviation 17.64 years). Mean symptom duration was 21.63 months (standard deviation 41.94). The mean intraocular pressure was 13.87 mmHg. Forty-three different retinal diseases were diagnosed. The most common was retinal complications of diabetes, i.e., diabetic retinopathy (DR) alone, diabetic macular edema (DME) alone and a combination of DR and DME, which accounted for 13.7%, 5.6% and 9.3%, respectively (contributed 28.6% of the entire diagnosis). This was followed by retinal detachment (RD), in 219 eyes (15.4%), dry age-related macular degeneration (AMD) in 124 eyes (8.7%). Nearly half of the eyes were blind or severely visually impaired. Blindness occurred in 34.1% of eyes; severe visual impairment in 8.2% of eyes and 29.7% had normal vision. There were 469 patients who had systemic diseases. The common systemic diseases were hypertension in 169 patients (19.3% of the total number of patients), hypertension and diabetes in 156 patients (18%), and diabetes alone in 98 patients (11.1%). Sickle cell disease was present in 1.5%.Conclusion: There is need to invest in infrastructure, local training and development of systems for early detection and treatment of several retinal diseases in sub-Saharan Africa; DR and DME having the largest burden. Collaborative physician care and management of hypertension and diabetes could significantly reduce the burden of DR and DME.Keywords: vitreoretinal diseases, sub-Saharan Africa, diabetic retinopathy, macular edema, retinal detachment
