ABSTRACT
Diabetes is one of the principal cause of blindness in adults. The aim of the study is to evaluate the frequency of ocular complications and risk factors of diabetes. It's a multicentric prospective study on a representative sample of 285 diabetics. We performed a general and an ophthalmologic exam for all patients with retinal angiography and appropriate laboratory tests. Chi 2, Fisher, Mann and Whitney tests were used as statistical methods. Diabetic retinopathy was observed in 45, 2% of patients, cataract in 22%, glaucoma in 5%. Diabetic retinopathy frequency rises especially with duration of diabetes and bad glycaemic control. Blindness related to diabetic retinopathy was observed in 6, 25% and visual deficency in 12, 5%. The authors compared their results with litterature data. They emphasize on the great value of regular better glycaemic control and other associated metabolic disorders. We concluded that a regular ophthalmologic follow up is necessary for early diabetic retinopathy detection and treatment

ABSTRACT
Occupational injury represents 7,7 at 69,9% of the total ocular traumatisms. They can be a major source of visuel loss and blindness. The aim is to study the epidemiology of work-related ocular injuries: objects frequencies,works most exposed. We performed a prospective study that interest 78 patients having a work-related ocular traumatism during a 4 months period. They were admitted at ocular emergency All patients underwent an ophtalmologic examination completed with orbital radiography and echography. A medical and/or chirurgical appropriate treatment was institued. Occupationnal injury frequency was 9% of the whole ocular traumatisms in the same period. The mean age was 31 years. 55% of cases were under 30 years. 91% were male. Most exposed works were industrial and mecanical sectors In 70,5% of cases work-related eye injuries were caused by projectile objects. Most common lesion was corneal superficial foreign body [58%]. Open globe injury was noted in 8%. 95% of patients had no eye protection at the time of the accident. 13% were blind or unilateral partially sighted [according to the OMS classification]. The authors discussed the importance and different prevention strategies to prevent the risk of blindness and socio-economical cost of occupationnal accidents. There is a need for systematic periodic sensibilization to reduce these accidents and blindness
ABSTRACT
The main cause of oedematous branch retinal vein occlusion [BRVO] vision loss is persistence macular oedema. We studied 18 patients having oedematous branch retinal vein occlusion. An ophthalmologic exam completed with angiography and etiologic assessment were performed. Argon Laser macular grid photocoagulation was performed in 11 eyes where macular oedema had persisted for over 3 months with visual acuity under 5/10. In 45% of cases, occlusion occurs in superotemporal vein. Atherosclerosis risk factors are found in 88% of cases. The course was spontaneously favourable in 39% of cases. Improvement of visual acuity was obtained in 36% of cases treated with laser photocoagulation. Oedematous branch retinal vein occlusion outcome is variable; it can be favourable if veno-venous anastomosis develops rapidly, or unfavourable with persistent macular edema and decreased visual acuity. In the later case, grid macular phototcoagulation should be performed leading to macular edema regression. So, macular edema secondary to branch retinal vein occlusion can diseappear spontaneously and needs laser treatment only if it persists

Laurence Moon Bardet Biedl syndrome is an hereditary, rare and serious disease characterized by retinitis pigmentosa [R.P.] associated to systemic manifestations. The authors report two cases from the same family [a girl and her brother] suffering from such syndrome. Consanguinity was found among parents. The girl, 13 old year, was bilateral legally blind. On the other way, two first cousins were affected by such syndrome. In our study, this syndrome had an autosomal recessive mode of inheritence. The importance of an early diagnosis and prevention is discussed
