    ABSTRACT: Cataract induced by corticosteroids is an entity, which has been well described for a relatively long time, but this eventuality caused by the cutaneous application of corticosteroids remains inadequately reported. The purpose of this study was to describe cataract as one of the complications of the misuse of cutaneous application of corticosteroids. In eight patients seen for visual loss, bilateral cataract was discovered. The only probable etiology in these cases appeared to be the cutaneous application of corticosteroids. Indeed, the work-up and careful history performed did not uncover any other etiology. Eight patients, six women and two men, exhibited cataracts related to the application of topical corticosteroids. The age of the patients ranged between 39 and 45years. The cataracts were bilateral and posterior subcapsular alone or combined. The period of use of corticosteroids ranged from 5 to 10years. The products used consisted of a variety of chemicals including corticosteroids mainly in the form of traditionally manufactured soap, but also as ointment or other types of mixtures. Topical corticosteroids induce posterior subcapsular cataract. The mechanism of action is direct access to the eye without any hepatic-first pass effect on the corticosteroid in question. The increasingly frequent use of corticosteroids in African blacks for skin lightening raises concern regarding the risk of epidemic cataracts in young women attempting to lighten their skin to be beautiful. Increased public awareness should be undertaken to prevent this growing and harmful phenomenon.

    ABSTRACT: This study aimed to show that central serous chorioretinopathy is present in Ivory Coast and that the emotional and psychosocial context plays an important role in this disorder's pathogenesis. The authors report six central serous chorioretinopathy cases based on angiographic diagnosis, five in Black African subjects and one in a European subject. These cases were observed over a period of 2 years during the Ivorian political-military crisis. In a center where angiography has been a current practice since 1999, up to 2002 479 angiographies were done without a single central serous chorioretinopathy case being diagnosed. After the beginning of the political-military crisis, six cases of central serous chorioretinopathy were observed out of 417 angiographies over a period of 2 years. All the patients were males, between 20 and 50 years old, five were Black Africans and one was a white European. Their professions varied (a contractor, a soldier, a business executive, for example). The angiography showed break points in ink spots in the majority of the cases, with one case showing multiple break points. All the patients were emotionally distraught because of the uncertainty of the political situation. This study confirms that central serous chorioretinopathy does indeed exist in the Black African subject, as it exists in the leucoderma subject without discrimination. This study emphasizes the anxiety and extreme emotional context as an initiating factor in the occurrence of central serous chorioretinopathy.

    ABSTRACT: Optical coherence tomography has been used for many years, in particular in the field of the retinal imaging, and is a promising technique in the analysis of the anterior segment, providing a similar resolution to histology for ocular tissue. We present a collection of images obtained with the OCT3 (Carl Zeiss Meditec, Dublin, CA), with parameters set to obtain good-quality images of the iris and corneal structures. The OCT provides detailed analysis of the cornea, precise assessment of the dimensions and locations of corneal lesions - in the anterior-posterior plane as well as transversally or obliquely - with 10-microm precision, and the study of the iridocorneal angle and its dynamics. Using the highly precise OCT3 for retinal imaging, it is possible to obtain good-quality anterior segment imaging, which makes the device highly versatile and thus increases reasons for acquiring this type of apparatus. OCT3 users should not neglect this potential of the device, already in wide use for examining the retina.

    ABSTRACT: Goldmann applanation tonometry is the reference method for measuring IOP. This tonometric model is influenced by corneal thickness, which varies according to race. Most studies have been conducted on Caucasian or Black American subjects. Studies on Black African subjects being rare, the goal of our study was to measure the central corneal thickness and its impact on Goldmann applanation tonometry on Black African subjects suffering from primary open-angle glaucoma (POAG). Our retrospective study focused on POAG eyes. The central corneal thickness was measured using an ultrasonic pachymeter (Quentel Médical). 340 eyes from 170 patients made up the sample. The mean age of our patients was 44.4 +/- 12.7 years, with a mean central corneal thickness of 519.6 +/- 32.6 microm. Of our patients, 57.6% had a central corneal thickness less than 527 microm, 30.6% between 527 and 560 microm, and 11.8% had a central corneal thickness greater than 560 microm. Compared to Black American and Caucasian subjects, the Black African glaucoma subject differs in the early age of glaucoma onset and the thinness of the cornea. Corneal thickness evaluation induces a potential error in IOP measurement on Black African glaucoma subjects. On the Black African subject, Goldmann tonometry is therefore affected by an error rate estimated at 69.4% (57.6% underevaluation and 11.8% overevaluation). Pachymetry is therefore a necessity for the Black African glaucoma patient requiring IOP adjustment.

    ABSTRACT: Objectif : Le but de l’étude est de montrer que la choriorétinopathie séreuse centrale (CRSC) est possible chez le patient noir, et que le contexte psychosocial émotionnel joue un rôle dans la pathogénie de l’affection. Patients et méthode : Les auteurs rapportent 6 cas de CRSC de diagnostic angiographique, chez 5 patients noirs africains et 1 patient européen, observés sur une période de 2 ans en pleine crise militaro-politique en Côte d’Ivoire. Résultats : Dans un centre où l’angiographie est de pratique courante depuis 1999 avec un total de 950 angiographies, 479 angiographies ont été réalisées sur une période de 3 ans jusqu’en 2002 sans que jamais une seule fois, une CRSC n’ait été diagnostiquée. Puis, après le déclenchement de la crise militaro-politique le 19 septembre 2002, 6 cas de choriorétinopathie séreuse centrale ont été diagnostiqués, sur une période de 2 ans dans une série de 417 angiographies. Les patients, tous de sexe masculin, 5 noirs africains et 1 Européen de race blanche, étaient âgés de 20 à 50 ans. Leurs professions étaient variées, entrepreneur, militaire, cadre de société. L’angiographie montrait des points de fuite en tache d’encre dans la majorité des cas. Le point de fuite était dans un seul cas multiple. Tous les patients étaient dans un état d’angoisse et d’émotion extrême du fait de l’incertitude du lendemain concernant leurs activités professionnelles. Conclusion : Cette étude permet de confirmer l’existence de la CRSC chez le patient noir Africain comme chez le sujet leucoderme sans discrimination. Elle met en évidence comme facteur déclenchant le contexte d’angoisse et d’émotion dans lequel la CRSC survient. L’étude met en évidence la relation étroite entre CRSC et stress.

    ABSTRACT: Introduction : L’imagerie par cohérence optique, technique éprouvée depuis de nombreuses années notamment dans le domaine de l’imagerie rétinienne, est prometteuse pour l’analyse du segment antérieur en permettant d’atteindre une définition des structures oculaires comparable à l’histologie. Matériel et méthode : Nous présentons un recueil de quelques clichés obtenus à l’aide d’un OCT-3 (Carl Zeiss Meditec, Dublin, CA) paramétré afin d’obtenir des images de bonne qualité des structures irido-cornéennes. Résultats : L’OCT permet une analyse fine de la cornée, une évaluation précise des dimensions et localisations de lésions cornéennes, aussi bien dans un plan antéropostérieur, que transversal ou oblique, avec une précision de l’ordre de 10 µm, et l’étude de l’angle irido-cornéen et sa dynamique. Discussion : À partir d’un outil très précis d’imagerie rétinienne qu’est l’OCT3, il est possible de réaliser une imagerie du segment antérieur de bonne qualité, ceci augmentant par-là même l’intérêt d’acquérir un tel appareil du fait de sa grande polyvalence. Conclusion : Il semble intéressant qu’une telle utilisation de l’OCT3 ne soit pas négligée par les utilisateurs de cet appareil déjà très répandu et qui a fait ses preuves pour l’examen du segment postérieur.

    ABSTRACT: The international literature seldom refers to eye measurements of the black African patient. Therefore, the various patterns where biometry elements are used as constituents deserve reconsideration as they may not correspond to the eye of the black patient of our region. This study provides true measurements for the black African patient in Ivory Coast. It also establishes hypotheses by extrapolating the role of measurements in pathologies such as glaucoma. and method: The study included 325 eyes of 217 male and female patients. All the patients underwent ocular keratometrics and echo biometrics to measure the depth of the anterior chamber, the width of the lens, and the total axial length with the ultrascan biometer using the contact method in A echometrics. The mean keratometry in women was significantly higher than in men (43.99 +/- 1.62 diopters vs 43.46 +/- 1.45 diopters). The anterior chamber was deeper in men (2.69 mm +/- 0.54 vs 2.53 mm +/- 0.48). The men's eyes were significantly longer, with an axial length of 23.26 mm +/- 1.07 vs 22.56 mm +/- 0.90. Significant biometric differences between men's and women's eyes, on the one hand, and between black African and white patients' eyes, on the other hand, can be observed. The reasons for these differences are several: they are natural, socioeconomic, and technical. If standard implant of a different power for black and white patients can be imagined, can we also infer that the biometrics of a black African patient predisposes him to a disorder such as glaucoma more than a white patient? Further in-depth studies could provide an answer to this question.

    ABSTRACT: We report a case of a 66-year-old woman presenting a central retinal artery occlusion with no cardiovascular risk factor, with assessment using supra-aortic artery ultrasonography showing total internal carotid artery thrombosis. When vascular thrombosis risk factors are absent, more in-depth assessment such as a supra-aortic artery angioscan can provide the diagnosis of arterial dissection on arterial fibromuscular dysplasia. Central retinal artery occlusion is a rare but severe pathology. Therefore it is very important not to neglect the etiological assessment, because it can be the revealing element of a severe pathology.

    ABSTRACT: The authors in this study intended to demonstrate that S-beta thalassemia can lead to severe ocular hemorrhagic risks, as is true of the sickle cell form. Both forms are also comparable in terms of the risk of aseptic necrosis of the femoral head. Out of the 18 patients studied, 13 (72.2%) had sickle cell retinopathy. Three of 13 patients had already developed new vessels and risked intravitreous hemorrhage. The authors recommend that more vigilance be mounted for the detection of S-beta thalassemia so as to benefit from rigorous and systematic follow-up and early treatment. Retinal argon laser photocoagulation is only effective if a clear diagnosis is made early.
