: To compare the success rates and safety of transscleral cyclophotocoagulation (TSCPC) for the treatment of refractory glaucoma using the slow coagulation technique and the conventional technique. : A retrospective, interventional case series of 44 patients (44 eyes) who underwent TSCPC using the slow coagulation technique (22 eyes) and conventional technique (22 eyes) in a tertiary hospital was done. The main outcome measures were success and complications.

Purpose: To identify clinical factors correlating with failure to control intraocular pressure (IOP) in primary angle-closure glaucoma (PACG) eyes with cataract after phacoemulsification or phacotrabeculectomy.

Design: Retrospective analysis of two prospective randomized controlled clinical trials.

Methods: Primary angle-closure glaucoma eyes with cataract received phacoemulsification or phacotrabeculectomy.

Purpose: To document the anatomical effects of clear lens extraction by phacoemulsification versus trabeculectomy on anterior chamber angle in patients with primary angle-closure glaucoma (PACG).

Methods: Gonioscopy and ultrasound biomicroscopy (UBM) were performed pre-operatively, and at 1 year after clear lens extraction or trabeculectomy in PACG eyes.

Results: Fifty PACG eyes of 50 patients were included.

Objective: To compare phacoemulsification versus trabeculectomy with adjunctive mitomycin C in medically uncontrolled chronic angle-closure glaucoma (CACG) without cataract.

Design: Prospective, randomized clinical trial.

Participants: Fifty medically uncontrolled CACG eyes without cataract of 50 patients.

Objective: To compare the complications of phacoemulsification alone vs combined phacotrabeculectomy in chronic angle-closure glaucoma (CACG) with coexisting cataract.

Methods: Patients with CACG with coexisting cataract recruited into 2 randomized controlled trials comparing phacoemulsification alone vs combined phacotrabeculectomy were pooled for analysis. The first trial recruited patients with medically controlled intraocular pressure, while the second trial recruited patients with medically uncontrolled intraocular pressure.

Purpose: To investigate whether the presence of silent cerebral infarct (SCI) is related to field progression in patients with newly diagnosed normal-tension glaucoma (NTG).

Design: Prospective cohort study.

Participants: A total of 286 eyes from 286 NTG patients: 64 with SCI (SCI+) and 222 without SCI (SCI-).

Purpose: To document anatomic effects of phacoemulsification versus combined phaco-trabeculectomy on drainage angle in primary angle closure glaucoma (PACG).

Methods: Indentation gonioscopy and ultrasound biomicroscopy were performed preoperatively, and then at 1 year after phacoemulsification alone or combined phaco-trabeculectomy in PACG patients.

Results: Seventy-two PACG eyes of 72 patients were included in this study.

Purpose: To compare the efficacy of early phacoemulsification versus laser peripheral iridotomy (LPI) in the prevention of intraocular pressure (IOP) rise in patients after acute primary angle closure (APAC).

Design: Prospective randomized controlled trial.

Participants: Sixty-two eyes of 62 Chinese subjects, with 31 eyes in each arm.

Purpose: To report the technique and surgical outcomes of microincision bimanual phacotrabeculectomy in eyes with glaucoma and coexisting cataract.

Setting: Glaucoma Service, Hong Kong Eye Hospital, Hong Kong SAR, China

Methods: Microincision bimanual phacoemulsification with a sleeveless phaco needle and irrigating chopper was performed in combination with trabeculectomy. Phacoemulsification was performed through 2 small clear corneal wounds, sparing the trabeculectomy site from trauma.

Purpose: A prospective observational case series to assess the prevalence of appositional angle closure in darkness among iridotomized Chinese eyes after acute primary angle closure (APAC) with the use of both clinical methods and ultrasound biomicroscopy.

Methods: Sixteen Chinese patients who had history of APAC and subsequent successful treatment with laser peripheral iridotomy were examined. Fourteen additional control subjects were studied.
