Intracorneal hematoma or hemorrhagic descemet detachment is a rare phenomenon. It has been previously described after nonpenetrating glaucoma surgeries such as canaloplasty, viscocanalostomy, and deep sclerectomy. In this report, we describe a rare case of intracorneal hematoma as a yet nondocumented complication after Ahmed glaucoma valve implant surgery.

Ab externo Schlemm's canal (SC) surgery (e.g., viscocanalostomy and canaloplasty) is a valuable alternative to glaucoma filtration surgery. It targets the abnormally high resistance to outflow in the trabecular meshwork (TM) and reestablishes the physiologic outflow system. In viscocanalostomy, viscoelastic substance is injected to dilate SC, which in turn leads to microdisruptions of the inner wall. In canaloplasty, the additional intracanalicular stent (suture or Stegmann Canal Expander®) keeps the canal patent and enhances the circumferential flow...

African descent is a well-documented risk factor for glaucoma development, progression, and medical and surgical failure. We reviewed the literature for evidence of outcomes disparities between Black and White populations after trabeculectomy, Ex-PRESS shunt, viscocanalostomy, canaloplasy, tube shunt, laser trabeculoplasty, and cyclophotocoagulation. There are reports of decreased surgical success in Black patients after trabeculectomy, Ex-PRESS shunt, tube-shunt, and canaloplasty. At this time, there is no strong evidence that any procedure is more effective for intraocular pressure control than standard trabeculectomy for Black patients...

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...

Exfoliative glaucoma is the most common type of secondary open-angle glaucoma worldwide. It is characterized by high intraocular pressure (IOP) and worse 24-hour IOP characteristics. In order to minimize progression, treatment of exfoliative glaucoma has to provide a low long-term mean IOP and good 24-hour IOP control. To achieve these goals, fixed-dose combination eye drops, argon and selective laser trabeculoplasty, and various forms of surgery (trabeculectomy, deep sclerectomy, viscocanalostomy, ab interno trabeculotomy, trabecular aspiration, and cataract surgery) all need to be considered during the long-term management of the disease...

BACKGROUND: Primary congenital glaucoma (PCG) manifests within the first few years of a child's life and is not associated with any other systemic or ocular abnormalities. PCG results in considerable morbidity even in developed countries. Several surgical techniques for treating this condition, and lowering the intraocular pressure (IOP) associated with it, have been described. OBJECTIVES: To compare the effectiveness and safety of different surgical techniques for PCG...
