[Treatment of retinal detachments with giant retinal tear. Retrospective study of 23 cases]. / Traitement des décollements de rétine par déchirure géante. Etude rétrospective à propos de 23 cas.

PURPOSE: Report of anatomic and functional results of retinal detachment with giant retinal tear. PATIENTS AND METHODS: Retrospective study of 23 cases of retinal detachment resulting from retinal tear of 90 degrees or more: five had a history of ocular trauma, 14 had myopia, and six had no risk for giant retinal tear. Episcleral surgery was performed on cases of giant retinal tear less than 180 degrees , with no advanced proliferative vitreoretinopathy and no inversion of the retinal flap. A vitrectomy was performed on other cases. Scleral buckle was associated with vitrectomy in cases of advanced vitreoretinopathy. RESULTS: The degree of success in the primary surgery was 50% in vitreoretinal surgery, 75% in vitreoretinal surgery with an encircling scleral buckle, and 86.4% in episcleral surgery. Of the seven failed cases, six patients underwent second-intention surgery: vitrectomy in four cases (primary surgery: the first case, episcleral surgery; the next two cases, vitrectomy; and in the fourth, vitrectomy with an encircling scleral buckle). In the last two cases, vitrectomy with scleral buckle was used (the primary surgery in both cases was vitreoretinal surgery). The final success rate was 78.2%, and the average follow-up was 32 months. Through the last test, postsurgery acute vision improved in 16 cases. CONCLUSION: Vitrectomy is often recommended to repair retinal detachment with giant retinal tear. However, episcleral surgery can be used if the giant tear is less than 180 degrees , the proliferative vitreoretinopathy is not advanced, and the retina flap is not inverted. The scleral buckle must be associated with the vitrectomy in cases of inferior giant retinal tear even if the proliferative vitreoretinopathy is not advanced.

[Craniofacial fibrous dysplasia: a case report]. / La dysplasie fibreuse cranio-faciale. A propos d'un cas.

Fibrous dysplasia is classified among benign bone tumors. It is a bone development anomaly characterized by hamartoma proliferation of fibrous tissue within the medullary bone, with secondary bony metaplasia, producing immature, newly formed and weakly calcified bone, without maturation of the osteoblast. It can be monostotic or polyostotic. The craniofacial localization occurs in 10%-25% of cases in monostotic forms and in 50% of cases in polyostotic forms. Fibrous dysplasia essentially affects children and young adults, with no sex preference. Its diagnosis is not always straightforward because the functional symptomology is often absent or not specific. Medical imagery is necessary and in difficult cases a bone biopsy. The major complication of the illness remains sarcomatous degeneration. Only symptomatic forms are treated. We report an observation of craniofacial fibrous dysplasia affecting a child and discovery of proptosis, with no other ocular or general functional signs.
