Introduction: Ametropia is common in children and cause strabismus and amblyopia. The goal was to establish its prevalence in a hospital setting among Senegalese children., Patients and Methods: This was a retrospective study of patients under 15 years of age with clear ocular media. The marital status, circumstances of discovery, and results of cycloplegic refraction were recorded., Results: Of 1506 children, 175 demonstrated ametropia. The mean age was 8 years, and the male : female ratio was 0.68. Family history of ametropia was present in 8.5 %. Decreased VA was present in 39.66 %, headache 10.06 %, and strabismus 4.47 %. Automated refraction in 109 patients and skiascopy in one patient showed 58.18 % cases of myopia, 18.18 % of hyperopia and 36.57 % of astigmatism., Discussion: The most common ametropia was myopia. Patients were referred for symptomatic ametropia., Conclusion: Screening for ametropia might occur earlier if it is associated with pediatric monitoring in our regions., (Copyright © 2019 Elsevier Masson SAS.

Introduction: Our goal was to evaluate the normal macular thickness in Blacks by OCT and to determine socio-demographic and clinical parameters which may influence it., Materials and Methods: This was a multicenter, prospective, descriptive study over 6 months. It included Black adults followed in the ophthalmology departments of Abass Ndao and Aristide-Le-Dantec hospitals in Dakar. Included subjects had corrected visual acuity of 10/10 (0 logMAR) and P2 (+0.1 logMAR), clear ocular media, and no retinal abnormalities. We used the Topcon 3D 2000 OCT to measure the central thicknesses of the cornea (CT) and of the macula (MT), and cup to disc ratio (C/D) in each eye. Socio-demographic, clinical and tomographic data were collected on a survey form and correlated to the MT. The analysis was carried out by the Epi info 7 software. We used the Chi 2 comparison test with a P value˂0.05., Results: One hundred and nine patients were included. The mean age was 27.39 years with a male/female ratio of 0.65. The subjects were emmetropic in 54.13% of cases. The mean CT was 519.97μm, the mean C/D was 0.23, and the mean MT was 264.35μm. The P-value (P) was greater than or equal to 0.1 for all the factors studied., Conclusion: MT in our study was lower than that of Whites, and the various parameters studied did not demonstrate a statistically significant influence on MT., (Copyright © 2018 Elsevier Masson SAS.

Purpose: To appreciate the epidemiological characteristics and to show the therapeutic aspects of the giant retinal tears., Patients and Methods: We conducted a retrospective study from January 2014 to June 2017 on subjects with giant retinal tears. Patients with media opacities limiting examination were excluded., Results: We identified 17 cases of giant retinal tears. The frequency of detachments related to a giant retinal tear was 17% compared to all retinal tears. The mean age was 50.75 years with a sex ratio (M/F) of 6.5. We found three cases of high myopia, one case of hyperopia and four trauma cases. All patients had a decrease in visual acuity. The average time to consultation was four weeks. The mean intraocular pressure was 8mmHg. The tear was found in the left eye in eight cases and in the right eye in five cases; two cases were bilateral. We performed intraocular surgery in five eyes and laser in four eyes. We achieved anatomical reattachment and functional improvement in all operated patients., Comments and Conclusion: The prognosis of a giant retinal tear remains guarded, especially if patients are seen and treated late. Laser photocoagulation of giant tears remains effective, especially in cases of early diagnosis., (Copyright © 2019 Elsevier Masson SAS. All rights reserved.)

Introduction: In Senegal, 10% of the population are said to be carriers of hemoglobin S, the most widespread hemoglobinopathy in the world. It is responsible for potentially blinding ophthalmological manifestations. Few practitioners refer patients for ophthalmologic screening. The goal of our study was to assess the level of knowledge of practitioners of the blinding ocular lesions of sickle cell disease., Materials and Methods: A cross-sectional prospective study was carried out over five months. It included Dakar university hospital practitioners aside from ophthalmologists. On the survey form, each practitioner specified his or her specialty and responded to eight questions regarding sickle cell patients seen in consultation, knowledge of the blinding lesions related to the disease, and ocular monitoring for blinding systemic diseases. The practitioners were divided into three groups: department of medicine and medical specialties (group I), surgery and surgical specialties (group II), and biology and functional testing (group III). The descriptive analysis was done with the EPI-INFO software version 6.04., Results: The participation rate was 45.88%. Group I represented 45.29% of the sample, Group II 35.85% and Group III 18.86%. In all, 87.73% of practitioners saw sickle cell patients in consultation, 75.47% were aware of ocular involvement related to sickle cell disease, and 58.49% were aware of blinding lesions. 94.62% of practitioners saw sickle cell disease patients without systematically recommending ophthalmological consultation., Conclusion: Practitioners' level of knowledge of the blinding ocular lesions of sickle cell disease is considered to be low., (Copyright © 2018.

Purpose: The purpose was to record the causes of leukocoria among children under 10years of age and to determine the proportion of rare causes of leukocoria., Patients and Methods: This retrospective study was conducted over a period of ten years, from January 1, 2004 to December 31, 2013, in patients under 10years of age who were referred for leukocoria., Results: Leukocoria represented one of the ten reasons for consultation among children under 10years of age. The mean age of our patients was 42.5months. In 76 % of cases, the leukocoria patients were children under 6years of age. Male patients were affected more commonly, with a sex-ratio of 1.5. Patients coming from Dakar and its suburbs represented two thirds of the total. Bilateral involvement represented 53.7 % of the total. Cataracts were responsible for 74.3 % of cases, retinoblastoma 20.58 %, retinal detachment 0.96 %, retinopathy of prematurity 0.96 %, pupillary membrane persistence 0.96 %, persistent hyperplastic primary vitreous 0.64 %, endophthalmitis 0.64 %, optic nerve coloboma 0.32 %, iris heterochromia 0.32 % and ametropia 0.32 %., Discussion: The total percentage of rare causes was 5.12 % in our study, including one case of hyperopia. These etiologies, although rare, do exist., Conclusion: Rare causes of leukocoria require special attention. The discovery of leukocoria necessitates rigorous etiological work-up. Ametropia must be a diagnosis of exclusion., (Copyright © 2017 Elsevier Masson SAS. All rights reserved.)

Introduction: Our goal is to assess the Quality of Life (QL) of our patients after cataract surgery., Materials and Methods: We performed a multicenter prospective study from July 2012 to December 2013 including patients undergoing cataract surgery, aged 18 and older. A survey sheet with sociodemographic data, clinical data and QL survey (VF-14) was given to each patient after surgery at day 7 (D7), one month (M1) and two months (M2) postoperatively. The final score was obtained by the following formula: QL=V (%)=(F __/__ C)×25. The data analysis was performed using SPSS software., Results: A total of 100 patients were included, 56 men, and 61 years was the mean age. The mean QL score was 29.86% at D7, 73.97% at M1 and 81.21% at M2. Subjects between 18 and 30 years of age had a score of 90.15% vs. 82.52% at M2 for older patients. After optical correction, the quality of life scores increased from 83.22% at D7 to 93.18% at M2. Patients who did not have functional signs had a QL score of 83.94%. Anxious patients had a QL score of 44% at D7, 61.23% at M1 and 52.67% at M2., Conclusion: Good surgical outcomes require, in addition to clinical success, good quality of life. Several factors may influence this quality of life., (Copyright © 2017 Elsevier Masson SAS. All rights reserved.)

Purpose: To report the clinical investigation of isolated microspherophakia involving a Senegalese family in order to appreciate its functional impact., Observations: This is a rural family comprised of 7 members. The sibship included three girls and two boys. One of the girls, who lived in a distant zone, was unable to be examined. Of all the examined members of the family, only the father was unaffected by the illness. There was no consanguinity. The general medical examination was normal. The best-corrected visual acuity (VA) for the girls was 2/10. For one of the boys, BCVA was 8/10 for both eyes, and for the other, BCVA was 10/10 for the right eye and 8/10 for the left eye. The mother's VA was 10/10 and P2 without correction. Myopia and astigmatism were present in the 4 children of the sibship. During the examination, we noted the presence of small crystalline lenses, which were very round and presented an abnormal visibility of the lens equator and zonular fibers. The diagnosis of microspherophakia was confirmed by measurement of the lens diameters by ultrasound biomicroscopy. Complications were present in the girls, including pupillary block glaucoma and amblyopia for the elder, and retinal degeneration and amblyopia for the younger daughter. The elder daughter was managed medically with glaucoma drops. The younger daughter received optical correction and a prophylactic Argon LASER treatment. The two boys received optical correction. No treatment was recommended for the mother., Conclusion: Microspherophakia is a rare condition. Some serious complications can lead to amblyopia. A better multidisciplinary evaluation would allow for early detection and a better prognosis., (Copyright © 2016 Elsevier Masson SAS. All rights reserved.)

Purpose: To evaluate the type and frequency of the ocular lesions found in patients practicing artificial depigmentation., Patients and Method: We conducted a prospective study over 3 months involving 108 patients, of whom 72 underwent depigmentation, and 36 did not, representing the controls., Results: Among patients undergoing depigmentation, 100% were female, of whom 34.72% developed ocular lesions. Exogenous ochronosis lesions of the eyelid predominated (34.72%), followed by ocular ochronosis (25.81%). Cataract (19.35%) and glaucoma (6.45%) were the least frequent. Among the untreated, only 19.44% had ocular lesions. These included cataract (57.14%) and glaucoma (42.86%). Ocular lesions were more frequent in patients using products containing hydroquinone., Conclusion: Artificial depigmentation is responsible for ocular lesions of variable severity. Our study highlights the importance of the raising awareness amongst the general population of the complications of artificial depigmentation, particularly the ocular lesions., (Copyright © 2015 Elsevier Masson SAS.

Introduction: Cycloplegia allows for an objective refraction in children. Atropine is the gold standard but causes prolonged blurred vision. Cyclopentolate is less effective but less disabling. Tropicamide is a weak cycloplegic. The purpose of this study was to evaluate a cyclopentolate and tropicamide combination (CTA) versus atropine for refraction in black children., Materials and Methods: We performed a prospective study between October 2011 and July 2012 on all children seen in consultation. Objective refraction was performed after cycloplegia with cyclopentolate 0.5% combined with tropicamide 0.5%, and then after cycloplegia with atropine., Results: Thirty-three patients were recruited, 14 boys and 19 girls. The average age was 9.9 years. The mean age of the patients was 9.9 years. Astigmatism was found in 96.9% of cases. It was 1.34±1.32 diopters with CTA and 1.35±1.22 diopters with atropine. The mean axis was 98.15 and 99.8, respectively. Hyperopia and myopia were found in 39 and 27 eyes, respectively with ACT (average 1.73 and 5.37 diopters), and in 41 and 19 eyes with atropine (average 2.06 and 6.11 diopters)., Discussion: There is a good correlation of results with regards to cylindrical and spherical refractive error between the two protocols. Atropine is the best cycloplegic, however ACT provides reliable results., Conclusion: The cyclopentolate-tropicamide combination is satisfactory for routine cycloplegia in children., (Copyright © 2014 Elsevier Masson SAS.
