[Use of silicone oil in vitreal hemorrhage complicating proliferated diabetic retinopathy].

Introduction: Vitreous hemorrhage is a frequent complication of proliferated diabetic retinopathy. Vitrectomy has vastly improved its prognosis. The purpose of this study was to evaluate the use of silicone oil in vitreal surgery in this indication.

[Keratoplasy for Peters anomaly (clinical case)].

Introduction: Peters anomaly is a primitive congenital glaucoma characterised by a central corneal leukoma. Therefore, keratoplasty is essential in addition to the specific treatment of the glaucoma. We aim to study the particularities and the evolutional ways of penetrating keratoplasty in Peters anomaly by presenting a clinical case treated in our service.

[Iris mammillations: three case reports].

Introduction: Iris mammillations are congenital abnormalities characterized by vitiliform protuberances regularly spaced on the surface of a velvety iris. They can be either isolated or associated with melanocytosis involving iris, sclera or periocular tissues, resulting in a risk for uveal melanoma. They can be complicated by ocular hypertension.

[Retrobulbar anesthesia during keratolplasty].

Aim: A restrospective study was carried in order to evaluate the efficacy and safety of retrobulbar anaesthesia during keratoplasty.

Methods: Of 250 consecutive keratoplasty, 30 (12%) were performed under retrobulbar anaesthesia. Patients received a mean volume of 12 ml, composed of etidocaine (2/3), bupicaine (1/3) and hyaluronidase.
