Abstract
Background Suprachoroidal surgery can lower intraocular pressure and medication use. There is currently no commercial suprachoroidal product on the market. Here, we report our 1 year results of a novel ciliary sulcus suprachoroidal microtube technique. Purpose To determine the real-world efficacy of intrascleral ciliary sulcus suprachoroidal microtube technique in Black and Afro-Latinx patients with glaucoma refractory to topical ocular hypertensive medications. Methods A retrospective non-comparative single center study of 36 Black and Afro-Latinx patients with glaucoma and pseudophakia who underwent intrascleral ciliary sulcus suprachoroidal microtube surgery for glaucoma as a stand-alone procedure at a single practice. Investigated parameters were number of medications, visual acuity (VA), intraocular pressure (IOP), mean deviation on visual field (VF) test. Success was defined as (a) IOP ⩽ 15 mmHg and or ⩾ 20% reduction in IOP and (b) a reduction in number of medications. We used paired t-test to compare baseline and follow-up parameters. Results We reviewed a total of 36 patients who had undergone the procedure. Twenty had success with 12-month follow-up in the study. The mean number of medications decreased significantly from 4.2 ± 1.0 preoperatively to 2.4 ± 1.7 in 12 months (p = 0.021) with five patients being medication free. In addition, the IOP decreased significantly from 21 ± 8.2 to 13.5 ± 4.4 mmHg (p = 0.032). In the 20 patients who had 12-month follow-up, the VA remained stable from Log Mar 0.62 ± 0.6-0.46 ± 0.6 (p = 0.052). VF in patients with successful procedure (no further interventions) remained stable from baseline mean deviation of -16.53 ± 10.04 to -16.82 ± 9.80 dB at 6-12 months. Adverse effects were transient and included IOP spike, hypotony, hyphema, and cornea edema that were treated and resolved. Conclusions This 12-month retrospective study demonstrated that intrascleral ciliary sulcus suprachoroidal microtube surgery can reduce IOP and medication burden in pseudophakic patients with glaucoma. However, despite several successes, surveillance should take place for IOP spikes, possible tube obstruction, and need for additional glaucoma surgery.

Abstract
Glaucoma is the primary cause of irreversible blindness worldwide. The current treatments are primarily based on drug usage or surgical operation to reduce intraocular pressure (IOP). However, it is expensive and requires patients to insist on taking the medicine for a long time. The suprachoroidal space (SCS) is the space between the choroid and the sclera, which forms part of the uveovortex pathway in the circulation of aqueous humor. So far, it is still challenging to realize the injection of hydrogels into the SCS with long-term duration. In this work, an in situ-forming polyzwitterionic polycarboxybetaine hydrogel is designed and injected to expand SCS to increase the drainage of aqueous humor from the eye via the uveovortex pathway, thus reducing IOP for at least 6 weeks, while commercial hyaluronic acid hydrogel can only last for about 4 weeks. The clinical ophthalmological safety assessment examination shows that the treatment of polyzwitterion hydrogel is well-tolerated that leads to minimal inflammatory reaction, and histopathology assessment demonstrates that the SCS is expanded after injection of the hydrogel. Further analysis of ultrasound biomicroscopy reveals that there is a strong correlation between IOP reduction and SCS expansion. In short, the polyzwitterion hydrogel developed in this work can prolong the period of IOP reduction by expanding SCS, thus treating ocular hypertension and glaucoma without resorting to drugs or regular surgery.

Abstract
Glaucoma remains a frequent serious complication following cataract surgery in children. The optimal approach to management for 'glaucoma following cataract surgery' (GFCS), one of the paediatric glaucoma subtypes, is an ongoing debate. This review evaluates the various management options available and aims to propose a clinical management strategy for GFCS cases. A literature search was conducted in four large databases (Cochrane, PubMed, Embase, and Web of Science), from 1995 up to December 2021. Thirty-nine studies-presenting (1) eyes with GFCS; a disease entity as defined by the Childhood Glaucoma Research Network Classification, (2) data on treatment outcomes, and (3) follow-up data of at least 6 months-were included. Included papers report on GFCS treated with angle surgery, trabeculectomy, glaucoma drainage device implantation (GDD), and cyclodestructive procedures. Medical therapy is the first-line treatment in GFCS, possibly to bridge time to surgery. Multiple surgical procedures are often required to adequately control GFCS. Angle surgery (360 degree) may be considered before proceeding to GDD implantation, since this technique offers good results and is less invasive. Literature suggests that GDD implantation gives the best chance for long-term IOP control in childhood GFCS and some studies put this technique forward as a good choice for primary surgery. Cyclodestruction seems to be effective in some cases with uncontrolled IOP. Trabeculectomy should be avoided, especially in children under the age of one year and children that are left aphakic. The authors provide a flowchart to guide the management of individual GFCS cases.

Abstract
We report the successful treatment of angle closure glaucoma and plateau iris with combined early cataract surgery/lensectomy, goniotomy, and transscleral cyclophotocoagulation. The underlying mechanism of angle closure and plateau iris was addressed with cataract extraction and goniosynechiolysis. Goniotomy was used to enhance trabecular meshwork outflow and lower intraocular pressure, and the "slow burn" transscleral cyclophotocoagulation was safely performed to reduce the size of the ciliary processes. The unique combinations of these procedures restored the iridocorneal angle anatomy to normalize IOP and prevent vision loss from glaucoma in patients with plateau iris. This is a cost-effective option with longer term efficacy.
