Background: Descemet's stripping endothelial keratoplasty (DSEK) is the most common procedure for corneal transplantation. The effect of a pre-existing glaucoma drainage device on long-term surgical outcomes is uncertain.

Methods: A retrospective chart review of all DSEK cases at an academic hospital over a 10-year period was conducted.

Purpose: To evaluate the safety and efficacy of combined iStent® trabecular micro-bypass device (Glaukos, Laguna Hills, CA) and phacoemulsification in eyes with primary angle closure disease.

Methods: A two-center prospective interventional case series of consecutive patients with primary angle closure (PAC) or primary angle closure glaucoma (PACG) on at least one glaucoma medication, who underwent iStent implantation with cataract surgery. Postoperatively, patients were assessed on days 1 and 7, and months 1, 3, 6, and 12.

Purpose: Develop an algorithm to predict the success of laser peripheral iridotomy (LPI) in primary angle closure suspect (PACS), using pretreatment anterior segment optical coherence tomography (ASOCT) scans.

Methods: A total of 69 eyes with PACS underwent LPI and time-domain ASOCT scans (temporal and nasal cuts) were performed before and after LPI. After LPI, success is defined as one or more angles changed from closed to open.

Cataract surgery is a common procedure, and cystoid macular edema (CME) is a sight-threatening complication. Prostaglandin analogues are the first-line therapy for glaucoma, but their effect on the risk for CME after phacoemulsification is unknown. A systematic search of Medline and PubMed was performed to determine the effect of the use of prostaglandin analogues (PGA) on the development of CME after cataract surgery.
