Prevalence of Refractive Errors among School Children Aged 5 to 15 Years Old at CHU-IOTA

Introduction: Undetected refractive errors constitute a health problem among school children who cannot take advantage of educational opportunities. The authors studied the prevalence of refractive errors in school children aged 5 to 15 at CHU-IOTA. Patients and Method: This is a prospective, descriptive cross-sectional study carried out in the ophthalmic-pediatrics department of CHU-IOTA, from October to November 2023. Results: We received 340 school children aged 5 to 15, among whom 111 presented ametropia, i.e. a prevalence of 32.65%. The average age was 11.42 ± 2.75 years and a sex ratio of 0.59. The average visual acuity was 4/10 (range 1/10 and 10/10). We found refractive defects: astigmatism 73.87%, hyperopia 23.87% of cases and myopia 2.25%. The decline in distance visual acuity was the most common functional sign. Ocular abnormalities associated with ametropia were dominated by allergic conjunctivitis (26.13%) and papillary excavation (6.31%) in astigmatics;allergic conjunctivitis (9.01%) and papillary excavation (7.20%) in hyperopic patients;turbid vitreous (0.90%), myopic choroidosis (0.45%) and allergic conjunctivitis (0.45%) in myopes. Conclusion: Refractive errors constitute a reality and a major public health problem among school children.

Prevalence of Ocular Trauma at the Reference Health Center (CSREF) of Kati

Introduction: The authors wanted to study the prevalence of ocular trauma in the ophthalmology unit of the CSREF of Kati. Patients and method: This is a retrospective study, covering the period from January to December 2015, carried out in the ophthalmology unit of the CSREF in Kati. Results: The sample consisted of 568 patients, or 6.82% of ophthalmological consultations. Children aged 0 to 14 years accounted for 154 (27.11%) of the trauma cases. Bruises constitute the main circumstance (58.1%) of eye trauma, followed by domestic accidents (15.6%). Closed globe ocular trauma was the main type of trauma (61.6%), followed by ocular adnexal trauma (30.1%) and open globe trauma (8.3%) in which the penetrating wound was the lesion, the least common (2.6%) but the most serious. Medical treatment was the most used therapeutic modality in 82.4% of cases, followed by surgery with 17.6% of cases. The evolution of the lesions after treatment was favorable in 85.6% of cases and unfavorable in 14.4% of cases. Complications were observed in 5.8% of cases and sequelae in 8.6% of cases. Conclusion: Ocular trauma constitutes an important reason for ophthalmological consultation at the CSREF of Kati. The severity of some of these lesions requires frequent recourse to surgery. The complexity of the treatment should encourage us to favor preventive measures.

Morning Glory Syndrome in Two (02) Malians: Case Report from IOTA-University Hospital

Background: First described by Handmann in 1929, the “Morning Glory Syndrome” is a rare congenital anomaly of the optic papilla whose notable ophthalmoscopic sign is papillary excavation associated with other ocular and/or non-ocular anomalies. Purpose: The main purpose of this study is to report 2 cases of this rare congenital papilla anomaly in 2 young Malian adults diagnosed in the IOTA-University Hospital respectively in January and May 2020. Materials and methods: In our study, we have included two cases of male gender. Results: In the 1st case the defect concerned both papillae. It is also associated with other ocular malformations (bilateral macular reshaping and unilateral cataract), without associated cerebral defects. In the 2nd case, only one papilla was affected by the malformation and there was an absence of associated malformations of other ocular and cerebral structures. Discussion: The Morning Glory Syndrome is part of the group of congenital defects of the optic nerve. It is often referred to as ectasia coloboma of the optical papilla or bindweed flower-like optical papilla because of its similarity to the tropical flower known as “bindweed”. Its exact pathogenesis remains unknown, but it is linked to the poor development of the posterior sclera and lamina cribrosa during gestation. Conclusion: Morning Glory Syndrome through papillary excavation and other associated ocular and/or cerebral malformations may be a threat to vision.

Bilateral Central Serous Chorioretinopathy (CRSC) in Pregnancy Complicated with Retroplacental Hematoma: About a Case

Introduction: Central serous chorioretinopathy (CSCR) is associated with serous sensorineural retinal detachment in the macular region. The condition that affects the male gender more than their female counterpart results from focal leakage disturbance of retinal pigment epithelial cells and choroidal abnormalities. The corticosteroid is highlighted as one of the major factors that promote the occurrence of CSCR. Stress and pregnancy, especially in the third trimester, have also been reported by some authors. Central serous chorioretinopathy associated with pregnancy complicated by retroplacental hematoma is a rare event. Observation: We report the case of a pregnant woman at approximately 34 weeks of amenorrhea who presented a sudden and severe drop in visual acuity on a pregnancy complicated by retroplacental hematoma and delivered by cesarean section. The diagnosis was based on clinical arguments associated with photos of the retina made by the MII Ret Cam device (Made In India, Retinoscope Camera) highlighting the lifting of the macular region. Ophthalmological monitoring without medical or physical treatment was instituted. At two months of progression without treatment, bilateral visual acuity was 10/10. Conclusion: Central serous chorioretinopathy and pregnancy is not unusual;however, its bilateral and brutal form in a context of pregnancy complicated by retroplacental hematoma is rare. Despite this favorable evolution, monitoring remains necessary in order to prevent recurrences and complications.

Argon Laser Treatment of Retinal Lesions at the CHU-IOTA in Bamako, Mali

Introduction: There are many types of retinal lesions: exudative, degenerative and post-traumatic. Some can lead to retinal detachment (RD). The treatment indicated for these neovascular diseases of the eye is retinal photocoagulation with the Argon laser. The aim of this study was to investigate retinal lesions treated with the Argon laser at IOTA University Hospital. Patients and Method: This was a prospective cross-sectional study over a 9-month period. All patients seen at CHU IOTA during our study period who presented with a retinal pathology treated with the Argon laser or a retinal detachment with a giant tear in the contralateral eye and who had given their consent were included. One session consisted of treating the maximum surface area of half a retina. Results: We collected 263 cases. The age group 40 to 60 years was the most represented with 48.7%. Diabetes was the most frequent antecedent with 47.1%. Neovessels were the most common type of lesion, accounting for 68.4% of cases. Pan-retinal photocoagulation was performed in 74.5% of patients. Conclusion: Retinal lesions represent a major risk of functional visual loss. Physical treatment with retinal photocoagulation has a curative effect on ischaemic lesions and a preventive effect on retinal detachment.
