Demographic and clinical profile of patients with juvenile onset open angle glaucoma in southwestern Nigeria

Background: This was a non-comparative, retrospective review of patients diagnosed with juvenile open angle glaucoma (JOAG) in the eye clinic of a tertiary hospital in southwestern Nigeria.Objective: To document the demographic characteristics, clinical features and treatment outcome of the patients diagnosed with JOAG.Materials and Methods: Data were extracted from the clinical record of patients diagnosed with JOAG in the eye clinic of the University College Hospital, Ibadan, Nigeria, between January 2001 and December 2005. Such data included the basic demographic data, the clinical characteristic of the patients and the outcome of their treatment.Results: Twenty-nine patients were reviewed, which represents 3.4% of all newly diagnosed glaucoma patients seen in the out-patient section of the eye clinic of the University College Hospital, Ibadan, over the period reviewed. Eight (27.6%) patients were aged 20 years and below. The mean age was 25.1 ± SD 6.0 years. Eighteen (62.1%) had visual acuity of 6/18 or worse in the better eye at the time of presentation. The mean intraocular pressure (IOP) of the patients at presentation was 32.3 ± SD 15.2 mmHg. Eight (27.6%) patients defaulted within 6 months of presentation. The mean IOP for the 21 patients who were followed up on treatment for a mean period of 9.6 months was 17.0 ± SD 6.0 mmHg.Conclusion: Most patients with JOAG in this review presented with advanced form of the disease. Early detection through parent-driven school eye health program and community-based case detection could help in reducing the scourge arising from JOAG among our population

The Nigerian national blindness and visual impairment survey: Rationale, objectives and detailed methodology.

BACKGROUND: Despite having the largest population in Africa, Nigeria has no accurate population based data to plan and evaluate eye care services. A national survey was undertaken to estimate the prevalence and determine the major causes of blindness and low vision. This paper presents the detailed methodology used during the survey. METHODS: A nationally representative sample of persons aged 40 years and above was selected. Children aged 10-15 years and individuals aged <10 or 16-39 years with visual impairment were also included if they lived in households with an eligible adult. All participants had their height, weight, and blood pressure measured followed by assessment of presenting visual acuity, refractokeratomery, A-scan ultrasonography, visual fields and best corrected visual acuity. Anterior and posterior segments of each eye were examined with a torch and direct ophthalmoscope. Participants with visual acuity of < = 6/12 in one or both eyes underwent detailed examination including applanation tonometry, dilated slit lamp biomicroscopy, lens grading and fundus photography. All those who had undergone cataract surgery were refracted and best corrected vision recorded. Causes of visual impairment by eye and for the individual were determined using a clinical algorithm recommended by the World Health Organization. In addition, 1 in 7 adults also underwent a complete work up as described for those with vision < = 6/12 for constructing a normative data base for Nigerians. DISCUSSION: The field work for the study was completed in 30 months over the period 2005-2007 and covered 305 clusters across the entire country. Concurrently persons 40+ years were examined to form a normative data base. Analysis of the data is currently underway. CONCLUSION: The methodology used was robust and adequate to provide estimates on the prevalence and causes of blindness in Nigeria. The survey would also provide information on barriers to accessing services, quality of life of visually impaired individuals and also provide normative data for Nigerian eyes
