ABSTRACT
Background: Raising awareness and knowledge of glaucoma is a key means of enhancing people alertness, increasing regular eye screening practice, and the chance of identifying undetected cases. Health professionals other than ophthalmologists are often the first point of contact when patients seek medical advice. However, little is known about the awareness and knowledge of glaucoma among health care professionals in Ethiopia. The objective of this study was to determine general awareness and knowledge of glaucoma among health workers in Butajira General Hospital. Methods: Hospital-based cross-sectional study was conducted at Butajira Hospital in September and October 2021 among health care providers. All health workers except those on leave and the staff in the department of Ophthalmology were included in the study. The awareness and knowledge were assessed using a self-administered questionnaire. Descriptive statistics was computed to describe the study variable, and logistic regression was conducted to see associations between dependent and independent variables. Significant associations were declared at p-values <0.05. Result: This study showed that 184 (91.1%) had an awareness of glaucoma among the study participants, whereas 8.9% had never heard about glaucoma. Of those who were aware, only 42% have good knowledge. Professionals who had a history of eye examinations and family history of glaucoma were about 3.0 times more likely to have good knowledge. Conclusions: Fifty-eight percent of clinical professionals from Butajira Hospital had no awareness at all or had poor knowledge about glaucoma. Being a physician, history of eye examinations, and having a family history of glaucoma were factors related to glaucoma knowledge.

Background: Primary congenital glaucoma is potentially blinding condition characterized by elevated intraocular pressure and optic disc cupping. It is typically bilateral and usually manifest in the first year of life. Spontaneously arrested primary congenital glaucoma can occur, but it is very rare. Case Report: A 32-year-old male patient from North Shewa presented to the department of ophthalmology, Menelik II Hospital with deterioration of vision. On examination he had large corneas with horizontal diameter of 14 mm, increased axial length, faint corneal stromal opacity and Haab's striae of both eyes. Anterior chamber angles were wide open. His intraocular pressure, optic nerve head appearance and visual field in both eyes were normal. He had subluxated dense cataract of the right eye. Conclusion: Late presentation with sequelae of primary congenital glaucoma without optic neuropathy is possible. Regular follow-up of spontaneously arrested congenital glaucoma and scleral fixation of intraocular lens is recommended.

BACKGROUND: Selective laser trabeculoplasty (SLT) is a safe and effective treatment modality for lowering intraocular pressure (IOP). PURPOSE: To determine the efficacy and safety of SLT among Ethiopian patients with primary open-angle glaucoma (POAG), pseudoexfoliation glaucoma (PXG), and ocular hypertension (OHT). METHOD: A prospective, nonrandomized interventional study was conducted at Menelik II Hospital, Ethiopia. Patients on antiglaucoma medication with uncontrolled IOP and those patients treated for the first time with 360 degrees of SLT were included. Success was defined as an IOP lowering of > 20% from baseline without repeat treatment. RESULT: A total of 95 eyes of 61 patients with a diagnosis of OAG and OHT were enrolled. The diagnosis was POAG in 55 (57.9%) eyes, PXG in 22 (23.2%) eyes, and OHT in 18 (18.9%) eyes. Seventy (73.7%) eyes were on medications, and 25 (26.3%) eyes were treated with laser as primary therapy. The mean (SD) baseline IOP and medication were 24.3 ± 2.5 mmHg and 1.29 ± 1.01, respectively. The one-year mean (SD) IOP reduction was 6.7 ± 4.2 mmHg and medication reduction was 0.26 ± 1.34. The overall IOP reduction at 12 months was 27.6%, and the success rate was 60%. The mean IOP (SD) reduction for patients who were treated for the first time with laser and on antiglaucoma medication was 6.5 ± 3.1 mmHg and 6.8 ± 2.8 mmHg, respectively. Post-SLT, patients experienced transient ocular pain, brow ache, headache, and/or blurring of vision in 31.6%, anterior chamber reaction in 36.8%, and IOP spike ≥ 6 mmHg in 11.6%. CONCLUSION: SLT is an effective and safe treatment modality for OHT, POAG, and PXG among Ethiopian patients either as a first-line treatment or as an adjunct to topical glaucoma treatment.
ABSTRACT
PRéCIS:: In a case-control study, skin pigmentation was not statistically significantly different when comparing glaucoma patients to those without glaucoma. PURPOSE: Darker skin color has been implicated as a risk factor for glaucoma based on previous studies' subjective assessments of skin pigmentation. This study used objective measurements to determine whether cutaneous pigmentation is a risk factor for glaucoma. METHODS: This case-control study was conducted at Menelik II Tertiary Referral Hospital in Addis Ababa, Ethiopia. Patients aged 40 years or older from the glaucoma clinic who were being scheduled for trabeculectomy were enrolled as cases and age-matched patients without glaucoma from other clinics at Menelik II Tertiary Referral Hospital were enrolled as controls. A Dermacatch device was used to capture melanin measurements in triplicate from the inner arm of each participant. The exposure variable of interest was the median of the triplicate skin melanin measurements, in arbitrary units. The outcome of interest was presence of glaucoma. RESULTS: Agreement between the triplicate inner arm melanin measurements was high, with an intraclass correlation of 0.99 (95% confidence interval, 0.98-0.99). Mean melanin values were 704 units (SD 94) in 76 cases and 694 units (SD 93) in 152 controls. Melanin was not statistically significantly associated with glaucoma after adjusting for sex and season of measurement (ie, dry vs. rainy), with an odds ratio of 1.15 (95% confidence interval, 0.59-2.24) per 100 units of inner arm melanin. CONCLUSION: This study failed to find a significant association between skin pigmentation and glaucoma using an objective and reproducible assessment of pigmentation.

PRECIS: A teleglaucoma case-finding model was utilized in Ethiopia using a high-risk case identification approach. An overall 7.9% of patients had definite glaucoma, and 13.8% were glaucoma suspects. Most cases could be managed medically. BACKGROUND: This study was carried out to analyze disease prevalence and clinical referral pathways for high-risk patients assessed through a hospital-based teleglaucoma case-finding program. METHODS: Patients over the age of 35 years were referred from outpatient diabetic and hypertensive clinics. Through a teleglaucoma consultation, a glaucoma specialist provided remote diagnosis and management recommendations. Patient referral pathways were analyzed. Part way through the program, frontline ophthalmic nurses and optometrists were empowered to refer patients to be seen by general ophthalmologists within a week if patients met high-risk criteria. Qualitative stakeholder feedback was also obtained. RESULTS: A total of 1002 patients (53% female) were assessed with a mean age of 51.0±11.7 years. The prevalence of glaucoma and glaucoma suspects was 7.9% (79 cases) and 13.8% (138 cases), respectively. Retinopathy was found in 9.1%, with hypertensive retinopathy (2.7%) and diabetic retinopathy (2.5%) representing the majority of cases. Age-related macular degeneration was present in 1.5% and cataract in 16%. An overall 63% of cases were without organic eye disease. 35% of patients were referred to a general ophthalmologist, 0.7% to a glaucoma specialist (for surgery), 1.5% to a retina specialist, and 17.7% to an optometrist for further care. Qualitative analysis revealed that stakeholders felt the value of teleglaucoma would be in triaging patients requiring more urgent management and in identifying disease at an earlier stage. CONCLUSIONS: There is a high prevalence of glaucoma in Ethiopian patients assessed through this teleglaucoma program. This model and study have also demonstrated various principles behind telemedicine, such as the development of an intelligent triage system, case-finding for a variety of diseases, and consideration of optimal patient flow/referral pathways.

PURPOSE: To determine the incidence of progression of primary open-angle glaucoma at individual levels of mean intraocular pressure (IOP) in patients in Ethiopia. METHODS: A retrospective, multicenter, cohort analysis of patient records with at least 5 years of potential follow-up were evaluated for risk factors associated with progressive optic disc and visual field loss. RESULTS: There were 300 patients with the potential of 5 years of follow-up. In total, 166 patients progressed before 5 years and 134 remained stable for the full 5-year follow-up period. Of the total sample, 84% of patients with IOPs < or =19 (n=117/139), 53% of patients with IOPs of 20 (n=9/17), 14% of patients with IOPs of 21-24 (n=9/63), and 0% of the patients with IOPs of > or =25 mmHg (n=0/79) remained stable over at least 5 years. The mean IOP was 17.4+/-2.1 in the stable group and 25.0+/-5.9 mmHg in the progressed group (p<0.0001). The highest average peak IOP was 24.5+/-4.5 in the stable group and 29.0+/-6.1 mmHg in the progressed group (p<0.0001). A multivariant regression analysis to determine risk factors for progression was positive for mean IOP (p=0.0097). CONCLUSIONS: This study suggests that IOP reduction in a developing country, despite potential limitations in diagnostic techniques, follow-up, and compliance, can be effective in reducing the risk of glaucomatous progression over long-term follow-up.
