Epidemiological profile of patients with uveitis in Boko and Parakou, in northern Bénin.

To describe the epidemiology of uveitis in northern Bénin. This retrospective study carried out from records describing 10 years of uveitis care in 2 eye clinics in northern Bénin. The sample of 623 eyes with uveitis in 489 patients accounted for 1.0% of all consultations. A male predominance was observed with a sex-ratio of 1.5 (297 m/192 F). The patients' mean age was 35.7 ± 16.1 years, and the age range most often affected was 20-39 years. The uveitis was anterior in 32.3 %, posterior in 29.0 %, intermediate in 28.1% and total (panuveitis) in 10.6%. The cause was undetermined in 85.7 % of cases and identified in 14.3%, including toxoplasmosis in 47 cases (7.5%) and herpes zoster in 20 cases (3.2%). Outpatients accounted for all cases, and all received topical corticosteroids. Some complications were observed. Uveitis has a prevalence rate of 1% in northern Bénin. It caused blindness in 9.8% of affected eyes and impaired vision in 49.3%.

[Influence of ethnic and eye condition on ultrasound A in ophthalmology at UHNC-HKM of Cotonou]. / Influence de l'ethnie et de l'etat oculaire sur l'echographie a en ophtalmologie au CNHU HKM de Cotonou.

PURPOSE: To study impact of sociocultural groups and ocular condition on biometric data at University and Hospital National Center of Cotonou PATIENTS AND METHODS: We conducted a descriptive cross-sectional study from 1st January to March 31, 2009 in the eye clinic at CNHU-HKM of Cotonou. It involved 116 patients aged over 16 years and Beninese nationality. RESULTS: The mean age was 48 years ± 15.7. The sex ratio was 0.78. The "fon" socio-cultural's group was the largest with 43.96%. The eye condition was normal in 79 cases (68.10%). Primary glaucoma with open angle (OAPG) and cataract were observed in respectively 18.10% and 13.79%. Biometrics eye was not influenced by the socio-cultural groups, or by the OAPG. In contrast, cataract induced increase in the lens's thickness and reducing the depth of anterior chamber. CONCLUSION: The lens plays a key role in changing the biometrics of the anterior segment.

[Proliferative sickle cell retinopathy revealing Glanzmann thrombasthenia]. / Rétinopathie drépanocytaire proliférante révélatrice d'une thrombasthénie de Glanzmann.

Glanzmann thrombasthenia is a rare qualitative platelet abnormality of autosomal recessive transmission caused by absence of GP IIb/IIIa and resulting in disturbance of platelet aggregation and bleeding time extension. We report the case of a 16-year-old female suffering from SC sickle cell disease and presenting with bilateral vitreous hemorrhage revealing Glanzmann thrombasthenia. Despite vitrectomy, the functional prognosis was poor. Indeed, association of a severe hemorrhagic disease and sickle cell retinopathy makes surgical management difficult.

Refraction abnomalities are especially frequent with schoolchildren and constitute a frequent motive of medical advice. Authors trys to identify the most frequent refraction abnormalities and their epidemiological characteristics in daily practice at CNHUU-HKM. A retrospective study has been made on a period of 3 years at the ophthalmological clinic at CNHU-HKM (university and hospital national center-HKM) of Cotonou. This study was made on schoolchildren aged from six to fifteen years old who have experienced the automatic refractomety. From 1er January 2000 to 31 December 2002, 93 children, that is 9,2%, went to the surgery for refraction disorders. Patients from 31 to 15 years old were the most represented (63,44%) male sex is prevailing with a sex-ratio of 1,06. on the whole, myopia is the most frequent refractive abnormality with 72,04% distributed in simple myopia (32,26%) and astigmatism myopia (39,78%). Fermale sex people are the most concerned with myopia ; symptomatology from myopia (1 patient out of 3). Finally, myopia gets worse when people get older and is probably due to work intensity. Appears from this study that refraction abnormalities are curable discases; information, education and communication meetings are necessary to heightin public awareness.

Treatment of detachment retinal is essentially surgical and making by external (scleral buckling) or internal (endocular chirurgy chirurgy) methid. Authors relate functional and anatomical result of retinal detachment in elderly's population. Retrospective study realized in ophthalmological clinic of University and Hospital Center of Tpirs; is concerning fifty-three patients mean aged of 76 years and treating to Irst January 1998 at 31 December 1999 by sclerall buckling in first intention. The authors have noticed one year after surgical treatment, an anatomical recuperation of 71,15 % (n=37) with 59,45 % of functional success superior to 4/10 degrees Seleral buckling can be also to considere as a valid treatment in case of retinal detachment trentment of clderly population.
