RESUMO
OBJECTIVE: The goal of this clinical case is to report a case of ophthalmic zoster in a five-year-old boy and to insist on the relevance of early antiviral treatment (aciclovir) so as to minimize corneal affection and preserve visual function. OBSERVATION: We report the case of a five-year-old boy of preschool age with no notable pathological history who came for consultation with a painful eruption affecting the forehead, the upper eyelid, the nose. The clinical examination showed many erythematous vesicles affecting the left hemi-face. The diagnosis of ophthalmic zoster has been retained. Minimum biological laboratory assessment is normal. The treatment was local antiseptic and systemic aciclovir with high dose for ten days. The evolution was favorable. Zoster is rare in children. The ophthalmic form is exceptional. The diagnosis is clinical and should mention some bladdery lesions grouped in bunches with a disposition which follows a metamere. It can be responsible for serious ocular complications. CONCLUSION: The particularity of our observation is the presence of zoster in an immunocompetent child and the ophthalmic localization, that remains exceptional in children.
RESUMO
PURPOSE: To determine the prevalence of POAG and its clinical features in a population aged 40years and over in Bejaia. METHODS: This was a descriptive, cross-sectional survey for analytical purposes in a representative sample from the municipality of Bejaia. The target population consists of residents of the municipality aged 40 and over who were examined in basic health facilities in the municipality of Bejaia, from May 31, 2015 to July 12, 2016. The visual field, OCT, vertical C/D and intraocular pressure (IOP) criteria were used to define whether or not primary open angle glaucoma was present. RESULTS: A total of 1484 people (99 %) participated in the study. The mean age of the study population was 57.97±10.77years, with a median of 56years and sex ratio of 1.07. The prevalence of glaucoma in our study was 5.5 %: POAG 4.6 % (95% CI=3.5-5.7); PACG 0.3 % (95 % CI=0.1, 0.7); secondary glaucoma 0.5 % (95 % CI=0.2-0.7). The prevalence of ocular hypertension was 3.0 % (95% CI=2.2-4.0). The age-adjusted prevalence was 0.8 % between 40 and 49years of age and 6.9% between 60 and 69years of age. The mean age was 66.76±9.31years for men and 67.68±12.10years for women. The mean IOP was 17.53±5.69mm Hg. The mean pachymetry was 518.3±34.3µm in the right eye and 517.4±33.9µm in the left eye. The mean cup/disc ratio was 0.7±0.2 in both eyes. Multivariate analysis of risk factors in our study showed that age and ocular hypertension were significantly associated with the presence of POAG. DISCUSSION: The prevalence of POAG is disparate in relation to the age difference, the method of recruitment and the diagnostic criteria: in Bejaia, it is 4.6 %; in Morocco: Marrakech 2.0 %, Fez 6.4 %; in Tunisia: Bardo 2.7 %, Mahdia 2.4 %. The prevalence of POAG increases exponentially with age without significant gender difference. The inclusion of suspect cases influences the prevalence (Beaver Dam, Namil Study). We found that the prevalence of OHT in our study approximates that of the BMES, but it did not show a significant increase with age. The mean CCT in Bejaia (526.35±34.86 microns) and Fez (522.16±41.45 microns) are comparable. The mean vertical C/D ratio in Bejaia was also comparable to data in the literature. A significant difference was observed in the mean median deviation (MD) between subjects with glaucoma and normal subjects. The retinal nerve fiber layer as well as the mean ganglion cell complex thickness in glaucoma subjects was significantly thinner than in healthy subjects. CONCLUSION: The prevalence of POAG is high, similar to that of people of African descent, but at older ages and among men. The rate of glaucoma in Bejaia rises significantly with age. Glaucoma is a major ocular health problem and will become increasingly important as the population ages.
