Retinal detachment in southwest Ethiopia: a hospital based prospective study.

PURPOSE: The incidence of retinal detachment in Blacks is generally considered to be low though there are few supporting studies in Africa. This study, thus, aimed at describing the clinical profile of patients with retinal detachment in Southwest Ethiopia. METHODS: A hospital-based study was done on all consecutive retinal detachment patients who presented to Jimma University Hospital over six months period. A semi-structured questionnaire was used to collect patients' sociodemographic characteristics and clinical history. Comprehensive anterior and posterior segment eye examinations were done and risk factors were sought for. Statistical tests were considered significant if P < 0.05. RESULTS: A total of 94 eyes of 80 patients (1.5%) had retinal detachment (RD) and about 69% of patients were symptomatic for over a month before presentation. The mean age was 41.4 years (SD ±16.5). Fourteen patients (17.5%) had bilateral RD. At presentation, 61 eyes (64.9%) were blind from RD and 11 (13.8%) patients were bilaterally blind from RD. Rhegmatogenous RD was seen in 55 eyes (58.5%) and tractional RD in 22 eyes (23.4%). The most common risk factors were ocular trauma (32 eyes, 34.0%), myopia (23 eyes, 24.5%), posterior uveitis (13 eyes, 13.8%) and diabetic retinopathy (9 eyes, 9.6%). Most retinal breaks (25 eyes, 43.1%) were superotemporal and horse-shoe tear was the most common (19 eyes, 20.2%). Macula was off in 77 eyes (81.9%) and 38 eyes (69.1% of RRD eyes) had grade C proliferative vitreoretinopathy (PVR). Macular status was significantly associated with PVR (P=0.011), and duration of symptoms (RR=1.25, 95%CI: 1.059-1.475, P=0.040). CONCLUSIONS: A significant numbers of patients with ocular problem had retinal detachment, and nearly two third of the patients presented late. Trauma and myopia were the most important risk factors. People should be educated to improve their health seeking behavior and use eye safety precautions to prevent ocular trauma.

Glaucoma subtypes in Ethiopian clinic patients.

BACKGROUND: Until population-based data become available in Ethiopia, hospital-based studies may reflect the distribution of the subtypes of glaucoma in certain parts of the country. PURPOSE: The main aim of this study was to determine the subtypes of glaucoma in Jimma University Hospital, Ethiopia. METHODS: A facility-based cross-sectional study was conducted in Jimma University Hospital from April 1, 2007 to March 30, 2008. The study population consisted of 335 consecutive new and follow-up patients with glaucoma diagnosed based on strict objective criteria. RESULTS: The mean (SD) age of the study patients was 57.0 (12.7) years (range, 8 to 90 y). The male to female ratio was 2.7:1. The 2 most common subtypes of glaucoma found were exfoliation glaucoma (35.2%) and primary open angle glaucoma (32.8%). Primary angle closure glaucoma was diagnosed in 18.5% of patients. CONCLUSIONS: The finding of exfoliation glaucoma as the most common subtype of glaucoma in the present clinic-based study is interesting. Such observation has never been reported from anywhere in Africa. We recommend community-based surveys to define the real distribution of the glaucoma subtypes in Ethiopia.

Patients' preoperative expectation and outcome of cataract surgery at jimma university specialized hospital -department of ophthalmology.

BACKGROUND: Patient's satisfaction for a given treatment is an important clinical outcome because a satisfied patient is more likely to comply with treatments, attend follow-ups and advocate the service to others. Therefore, knowing patients' expectations before a planned procedure or treatment and the actual level of satisfaction and fulfillment of their initial expectations thereafter is much helpful. As far as the knowledge and experience of the researchers is concerned, there has not been any study conducted in Ethiopia to find out about patients' preoperative expectations and postoperative level of satisfaction for actual outcomes. This study was therefore, conducted to describe and find out the relationship between preoperative expectations of cataract patients and the actual postoperative experience and their satisfaction level following the surgery at ophthalmology department in Jimma University Specialized Hospital. METHODS: A prospective cohort study of patients undergoing first eye cataract surgery was conducted from July 10 to Oct., 10, 2007 in the Ophthalmology department of Jimma University Specialized Hospital. Detailed interviews that included general and vision specific health status measures and patients' preoperative expectations for cataract surgery outcomes were performed followed by visual acuity testing. Postoperatively, visual acuity testing was taken again and patients' level of satisfaction with attained postoperative vision was assessed. Data were collected and filled in a separate questionnaire form for each patient, and entered into a computer and analyzed using SPSS for Windows version 12.0. RESULTS: Of the 200 patients operated for cataract, 179 (89.5%) were followed for the whole five weeks. The average expected preoperative Visual Function-15 score was 96.3, compared to an achieved (postoperative) Visual Function-15 score of just 96.2. However, the most unrealistic expectations observed were reading small prints and doing fine handiwork. The final pinhole visual acuity postoperatively was ≤ 6/18 in 126 (70.4%) patients. Of the 78 (39%) patients who were bilaterally blind preoperatively, 5 (2.5%) patients remained blind postoperatively. CONCLUSIONS: Significant improvements were obtained in clinical, functional, and perceived vision by cataract surgery involving extracapsular cataract extraction with posterior chamber intraocular lens implantations. Expectations regarding visual functioning after cataract surgery were very high, and in most cases and in most cases they were fulfilled.

Glaucoma awareness among people attending ophthalmic outreach services in Southwestern Ethiopia.

BACKGROUND: Individuals may need to be aware of glaucoma and seek assessment regularly in order to diagnose the condition early. Awareness of glaucoma has not been previously documented in an Ethiopian setting. OBJECTIVE: The main aim of this study was to assess the level of awareness of glaucoma among people attending outreach ophthalmic services. METHODS: We conducted a cross-sectional survey in April 2009 of all people 40 years of age or older who presented during a two-week outreach service period in Agaro town, southwestern Ethiopia. Data on demographics and awareness of glaucoma were collected through face to face interview using a pretested structured questionnaire. RESULTS: 340 people participated in the study. Their mean age was 54.5 (SD 10.6) years. About 43% were illiterates and 37.6% were farmers. Only eight people (2.4%) were aware of glaucoma. The association between awareness and attaining high school or better education was statistically significant (p < 0.0001). CONCLUSION: Awareness of glaucoma in this population is very low. An efficient information, education and communication (IEC) strategy needs to be designed to increase knowledge of the community about glaucoma so that early diagnosis and treatment of individuals with this condition may be possible.

Weill Marchesani syndrome with chronic angle closure glaucoma in Ethiopia: a case report.

Weill Marchesani syndrome (WMS) is a rare condition characterized by short stature, brachydactyly, joint stiffness, and characteristic eye abnormalities including microspherophakia, ectopia of the lens, severe myopia, and glaucoma. We report a typical case of WMS in an 18-year old female Ethiopian patient who presented with progressive visual loss from chronic angle closure glaucoma secondary to lens subluxation. Patients with WMS require early diagnosis in order to treat serious ocular and life-threatening systemic complications. To the best of our knowledge, only one case of the syndrome was previously reported in Africa.
