Glaucoma drainage device implantation and cyclophotocoagulation in the management of refractory glaucoma after Descemet-stripping automated endothelial keratoplasty.

Aim: To compare the surgical outcomes of glaucoma drainage device implantation (GDI) and trans-scleral neodymium:YAG cyclophotocoagulation (CPC) in the management of refractory glaucoma after Descemet-stripping automated endothelial keratoplasty (DSAEK).

Methods: This retrospective study on observational case series enrolled 29 patients who underwent DSAEK and posterior anti-glaucoma surgery (15 with GDI and 14 with CPC). The main outcome measures were intraocular pressure (IOP), glaucoma surgery success rate (defined as IOP of 6-21 mm Hg without additional anti-glaucoma operation), number of glaucoma medications, endothelial graft status, and best-corrected visual acuity (BCVA).

A focusing method on refraction topography measurement.

This paper introduces a novel focusing method Refraction Topography (RT) for wide-angle refraction measurement. The agreement of the test results obtained using RT is evaluated against simulation results and expected refraction. RT develops a refraction algorithm on fundus images at various focusing statuses.

Microscope-integrated optical coherence tomography for image-aided positioning of glaucoma surgery.

Most glaucoma surgeries involve creating new aqueous outflow pathways with the use of a small surgical instrument. This article reported a microscope-integrated, real-time, high-speed, swept-source optical coherence tomography system (SS-OCT) with a 1310-nm light source for glaucoma surgery. A special mechanism was designed to produce an adjustable system suitable for use in surgery.

Choroidal Thickness Decreased in Acute Primary Angle Closure Attacks with Elevated Intraocular Pressure.

Purpose: To study the choroidal thickness (CT) changes in patients having unilateral acute primary angle closure (APAC) attacks with elevated intraocular pressure (IOP).

Methods: This study included 23 patients with unilateral APAC attacked eyes. The CT at macular and peripapillary regions were measured in both eyes of the subjects using enhanced depth imaging-optical coherence tomography (EDI-OCT).

[Relationship between glucocorticoid receptors in the peripheral blood lymphocytes and trabecular meshwork and glucocorticoid induced glaucoma].

Objective: To measure the number of glucocorticoid receptors (GR) in the trabecular meshwork and peripheral blood lymphocytes of rabbits, and to explore their relationship with steroid-induced glaucoma.

Methods: Steroid-induced glaucoma model was induced by subconjunctival injection of 0.5 mg dexamethasone in the right eyes every two days for a month.
