Purpose: To identify risk factors for flat anterior chamber that required additional intervention in the postoperative period (90 days) after uncomplicated Baerveldt Glaucoma Implant (BGI) surgery.

Design: Retrospective, matched case-control study.

Methods: A total of 42 cases (eyes) that received BGI at Anne Bates Leach Eye Hospital between February 1, 2011, and January 1, 2019, and that developed flat anterior chamber were included.

Purpose: This study evaluated whether the rate of retinal nerve fiber layer (RNFL) thinning is faster in eyes receiving intravitreal injections than in fellow uninjected eyes among patients suspected of having or confirmed to have glaucoma and exudative age-related macular degeneration (AMD).

Design: Retrospective comparative cohort study.

Methods: Patients with a diagnosis of unilateral exudative AMD and confirmed to have or suspected of having glaucoma in both eyes receiving unilateral intravitreal injections were identified.

Purpose: To examine the short-term efficacy and safety of gonioscopy-assisted transluminal trabeculotomy (GATT) in a series of patients who developed glaucoma following vitreoretinal surgery.

Patients And Methods: Retrospective case series of consecutive patients aged above 18 years with secondary open-angle glaucoma following vitreoretinal surgery who had undergone GATT between January 2015 and June 2019. Eyes were excluded if there is<1 month of follow-up or glaucoma before vitreoretinal surgery.

Purpose: On rare occasions, patients with retinopathy of prematurity develop anterior segment ischemia after laser photocoagulation treatment. The purpose of this investigation was to describe the visual outcomes and the risk of phthisis bulbi after lensectomy in patients with history of retinopathy of prematurity laser photocoagulation and attached retinas at the time of lensectomy.

Methods: A retrospective case series including 3 patients who underwent diode laser photocoagulation for retinopathy of prematurity and developed unilateral anterior segment ischemia with subsequent cataract formation, and then phthisis bulbi after uncomplicated lensectomy.

Background: Plication is an alternative tightening procedure to resection. In monkeys, plication has been shown to preserve anterior segment circulation compared with full-tendon tenotomy, but this is unconfirmed in humans.

Purpose: To evaluate anterior segment circulation by iris angiography before and after strabismus surgery in humans.
