Introduction: Primary congenital glaucoma causes vision loss if intraocular pressure is uncontrolled. Nonpenetrating deep sclerectomy is effective in treating primary congenital glaucoma. However, the effects of inadvertent trabeculodescemetic window perforation remain unclear.

Purpose: To compare the outcomes of the Ahmed glaucoma valve (AGV) (New World Medical, Inc) with the Baerveldt glaucoma implant (BGI) (Johnson & Johnson Vision) in primary congenital glaucoma (PCG).
Methods: This was a retrospective review of children with PCG who underwent AGV or BGI implantation with a minimum follow-up of 6 months. Main outcome measures were intraocular pressure (IOP), the number of glaucoma medications, success rate, complications, and surgical revisions.
Prcis: In this retrospective study of patients with predominantly severe juvenile open-angle glaucoma, deep sclerectomy (DS) achieved a success rate [defined as intraocular pressure (IOP) between 5 to 18 mm Hg] of 72% at 3 years.
Purpose: The purpose of this study was to evaluate the safety and efficacy of DS in patients with juvenile open-angle glaucoma (JOAG).
Methods: A retrospective chart review of all JOAG patients that underwent DS with mitomycin C at a tertiary care eye center during the period from May 2014 to May 2019.
Purpose: To characterize the proteome of the iris in primary angle closure glaucoma (PACG).
Experimental Design: In this cross-sectional study, iris samples were obtained from surgical iridectomy of 48 adults with PACG and five normal controls. Peptides from iris were analysed using liquid chromatography-tandem mass spectrometry on an Orbitrap Q Exactive Plus mass spectrometer.
Purpose: To investigate the efficacy and safety of illuminated microcatheter-assisted trabeculotomy as a secondary procedure in patients with primary congenital glaucoma (PCG).
Methods: This retrospective case series included patients with PCG who underwent trabeculotomy using an illuminated microcatheter with the intent of catheterizing the full circumference of Schlemm's canal in a single procedure. Success was defined as intraocular pressure (IOP) ≤21 mmHg, with or without the use of glaucoma medications.
Purpose: To report the rates of success of Ahmed glaucoma valve (AGV) surgery in early childhood glaucoma and factors associated with success.
Methods: Children with primary congenital or early childhood secondary glaucoma who underwent AGV surgery over a 10-year period (one eye per child) at a single institution were identified. Surgical failure was defined as having one or more of the following: intraocular pressure of >21 mm Hg 3 months postoperatively, reoperation for glaucoma, and vision loss to no light perception.
A 70-year-old glaucoma patient who underwent Ahmed Glaucoma Valve (AGV) implantation developed orbital cellulitis (OC) 5 days postoperatively. On presentation, the valve was not exposed and no intraocular involvement was noted. After successful treatment of OC with intravenous and oral antibiotics, the patient presented to the clinic with the AGV completely extruded from the eye.

Dysregulation of extracellular matrix (ECM) molecules and cellular factors might contribute to increased hydraulic resistance to aqueous drainage. Therefore, we examined these molecules in failed AGV capsular tissue.
View Article and Find Full Text PDFPurpose: Encapsulation of the Ahmed glaucoma valve (AGV) plate is a common cause for postoperative elevation of intraocular pressure, especially in children. Many reports have described the outcomes of AGV revision in adults. However, the outcomes of AGV revision in children are poorly documented.
View Article and Find Full Text PDFPurpose: Ahmed glaucoma valve (AGV) implant is an aqueous shunt device used to control intraocular pressure in glaucoma. Implant failure results from impervious encapsulation of the shunt plate causing increased hydraulic resistance and raised intraocular pressure. We hypothesized that deregulation of fibrosis pathway contributes to capsular resistance.

Materials And Methods: LVD and MVD in normal human conjunctiva (n=8) and excised blebs in the hypocellular stroma and peribleb tissue (conjunctiva adjacent to hypocellular bleb tissue) (n=8) were evaluated by immunohistochemistry using antibodies raised against Lymphatic Vessel Endothelial Receptor 1 (D2-40, lymphatic endothelium) and CD34 (vascular endothelium). LVD and MVD counts were performed by light microscopy in 5 fields at ×20 magnification by 3 observers.
In this brief communication, we present the steps used to establish a web-based congenital glaucoma registry at our institution. The contents of a case report form (CRF) were developed by a group of glaucoma subspecialists. Information Technology (IT) specialists used Lime Survey softwareTM to create an electronic CRF.

Suprachoroidal hemorrhage is a complication associated with intraocular surgery that can occur both intraoperatively and postoperatively. Several intraoperative or postoperative risk factors have been identified. The use of low-molecular weight heparin (LMWH) is considered one of the risk factors in surgical cases (ocular or non ocular) and non-surgical cases.
View Article and Find Full Text PDFCurrently, there are numerous choices for the treatment of pediatric glaucoma depending on the type of glaucoma, the age of the patient, and other particularities of the condition discussed in this review. Traditionally, goniotomy and trabeculotomy ab externo have been the preferred choices of treatment for congenital glaucoma, and a variety of adult procedures adapted to children have been utilized for other types of pediatric glaucoma with variable results and complications. More recently, seton implantations of different types have become more popular to use in children, and newer techniques have become available including visualized cannulation and opening of Schlemm's canal, deep sclerectomy, trabectome, and milder more directed cyclodestructive procedures such as endolaser and transcleral diode laser cyclophotocoagulation.

Design: Registry-based cohort study.
Methods: Review of registry data that included new patients with congenital glaucoma seen between 2001 and 2003 (29 months); analysis of the demographic data and clinical features of primary and secondary congenital glaucoma at presentation.
Purpose: To study the long-term outcomes of surgical revision of leaking blebs after trabeculectomy and identify possible risk factors for failure.
Patient And Methods: A retrospective, nonrandomized, noncomparative interventional study of 34 eyes with late bleb leaks after trabeculectomy that underwent bleb excision with conjunctival advancement. The primary outcome measure was successful repair and control of intraocular pressure (IOP).
Purpose: To investigate brimonidine-related side effects and the efficacy of brimonidine in lowering intraocular pressure (IOP) in children with primary infantile and secondary glaucoma.
Study Design: Single-center, prospective, interventional, noncomparative case series.
Participants: Eighty-three children (mean age, 7.

Purpose: To investigate the expression of the apoptotic mediators in the retinas from human subjects with diabetes mellitus.
Methods: Ten donor eyes from five subjects with diabetes mellitus, and eight eyes from four nondiabetic subjects without known ocular disease serving as control subjects were examined. Immunohistochemical techniques were used with antibodies directed against glial fibrillary acidic protein (GFAP), caspase-3, Fas, Fas ligand (FasL), Bax, Bcl-2, survivin, p53, extracellular signal-regulated kinases (ERK1/2), and p38.
