RESUMO

Background: Chronic corneal ulcers still pose etiological and therapeutic challenge. They are serious complications and often associated with poor functional prognosis


Aim: We report the case of a patient with bilateral and chronic corneal ulcer revealing a rare familial form of bilateral agenesis of the lacrimal gland


Cases report: A 39-year-old man was referred to our department for bilateralchronic and sterile ulcer. The tear break-up time was less than one second and the schirmer test detected no wetting in 5 minutes. He mentioned that lacrimation had been totally absent even when crying as was the case of his brother and his sister. Orbital echography showed absence of lacrimal gland. Orbital magnetic resonance imaging revealed absence of both lacrimal glands. Our patients were treated with permanent topical artificial tears. We performed also permanent occlusion of lower lachrymal poncti to preserve basic tear flow


Conclusion: Congenital lacrimal gland agenesis is rare. We report, to our knowledge, the first case of Tunisian family with three patients suffering from bilateral lacrimal gland agenesis and the first documented familiarly cases diagnosed in adulthood

RESUMO

To study the epidemiological profile and the degree of severity of hyperopia in Tunisia primary school and to assess its effect on school performance. A cross-sectional, descriptive survey was conducted among 6-14 aged Tunisian children attending primary urban and rural schools. A total of 6192 children were selected using stratified random cluster sampling. Cycloplegic refractive error was measured among all children with uncorrected visual acuity less than 9/10 or signs of astheniopia. Hyperopia was defined as spherical equivalent [SE] >/= 2.0 diopters [D]. We have also searched a possible relation between degree of severity of hyperopia and school performance. The prevalence of hyperopia was 2.61%. The spherical equivalent mean was + 3.73 +/- 0.94 D. The mean age was 9.67 +/- 0.44 years. This prevalence was 2.77% in boys and 2.47% in girls. 3.13% of students were living in urban areas and 1.42% in rural areas. The hyperopia rate decreased significantly with age [p = 0.021], but it was not significantly related to gender [p=0.54]. The difference in the prevalence of hyperopia between urban and rural areas was not statistically significant [p = 0.067]. There was no significant association between the degree of severity of hyperopia and school performance [p=0.41]. In our study, the prevalence of hyperopia among schoolage children in Tunisia was 2.61%.The identification of this refractive error and its correction as soon as possible would ensure these children better visual comfort and a better education
