CASE PRESENTATION: An 81 year-old woman and a 63 year-old man developed a pre-Descemet haematoma after deep sclerectomy (DS), the former during the surgery itself and the latter during the early post-operative period. The surgical technique is decribed that led to the evacuation of the haematoma and the preservation of the integrity of trabeculo-Descemet membrane. The anterior-segment OCT findings after surgery are also presented. CONCLUSIONS: These are the first reported cases of pre-Descemet haematoma after DS that have been successfully repaired by an ab interno Descemet membranotomy...

PURPOSE: To describe a new ultrasound biomicroscopic (UBM) sign seen in patients who underwent deep sclerectomy (DS) as a surgical procedure for the management of uncontrolled primary open-angle glaucoma (POAG). The presence of this sign in ultrasound biomicroscopy is suggested to be an indicator of successful surgery. We would like to name this sign as the "dolphin head sign." DESIGN: Prospective interventional study. MATERIALS AND METHODS: Twenty-eight eyes of 17 patients with POAG underwent DS with intraoperative mitomycin C (MMC) 0...

Childhood glaucoma is known to be one of the most challenging conditions to manage. Surgical management is more complicated than in adults because of differences in anatomy from adults along with variations in anatomy caused by congenital and developmental anomalies, wide-ranging pathogenetic mechanisms, a more aggressive healing response, and a less predictable postoperative course. Challenges in postoperative examination and management in less cooperative children and the longer life expectancies preempting the need for future surgeries and reinterventions are also contributing factors...

We describe the case of an 18-year-old female patient who presented with vasodilation of the episcleral vessels in both eyes. The dilated vessels were more prominent in the right eye and, furthermore, examination of the fundus oculi showed a glaucomatous excavation of the right optic disc. No underlying eye or systemic disease was found as the cause for the vasodilation, therefore, Radius-Maumenee syndrome (idiopathic dilated episcleral vessels with secondary open angle glaucoma) was diagnosed. Radius-Maumenee syndrome is a diagnosis by exclusion...
