Augmented trabeculectomy with mitomycin C in primary congenital glaucoma

This study aimed to determine success of trabeculectomy augmented with mitomycin C (MMC) in children with primary congenital glaucoma (PCG) and document complications of this intervention. Over a two-year period, the authors treated 74 eyes of 42 children with PCG,...

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...

EEG changes following use of cyclopentolate 1% eye drops

Cycloplegic eye drops may affect the central nervous system. This study reports electroencephalogram (EEG) changes in a cohort of 6–15-year-old children. EEG recordings were taken after placebo and two doses of cyclopentolate 1% in 24 awake children (36 children had...

RCT review of surgery for open angle glaucoma

This systematic review and meta-analysis examined eight randomised controlled trials (RCTs) to compare the intraocular pressure (IOP) reducing effect of three types of microstent implantation (Hydrus, iStent, CyPass) combined with phacoemulsification versus phacoemulsification alone for patients with open-angle glaucoma (OAG)...
