3D Finite Element Modeling of Femtosecond Laser Trabeculotomy.
Lasers Surg Med
January 2025
ViaLase Inc., Aliso Viejo, California, USA.
Objectives: Femtosecond laser image guided high precision trabeculotomy (FLigHT) is a novel open-angle glaucoma treatment. The procedure non-invasively creates aqueous humor (AH) drainage channel from the anterior chamber (AC) to Schlemm's canal (SC) through the trabecular meshwork (TM) to decrease intraocular pressure (IOP). The purpose of this study was to develop a 3D finite element model (FEM) of the FLigHT procedure and to simulate clinical results for different drainage channel cross-sectional areas.

: Glaucomatous neuropathy, a progressive deterioration of retinal ganglion cells, is the leading cause of irreversible blindness worldwide. While elevated intraocular pressure (IOP) is a well-established modifiable risk factor, increasing attention is being directed towards IOP-independent factors, such as vascular alterations. Color Doppler imaging (CDI) is a prominent technique for investigating blood flow parameters in extraocular vessels.

To report the safety and effectiveness of selective laser trabeculoplasty (SLT) using the SLT mode of the VISULAS green laser in patients with primary open-angle glaucoma (POAG). Twelve months results are presented. Retrospective extension in 4 German centers of an initially prospective interventional multicenter 3-month clinical investigation using the VISULAS green SLT (Carl Zeiss Meditec AG, Jena, Germany) in patients with POAG who either needed treatment escalation or commenced treatment and had an IOP ≥ 17mmHg at baseline, with no previous glaucoma or other ocular surgery.

December 2024
Ophthalmology Department, Faculty of Medicine, Alexandria University, Alexandria, Egypt.
Purpose: To assess the outcome of combined phacoemulsification and 360-degree suture trabeculotomy ab externo in chronic angle closure glaucoma using a modified technique.
Methods: This is a retrospective clinical study that included 60 eyes of 60 patients who had undergone combined phacoemulsification and 360-degree suture trabeculotomy ab externo for the treatment of primary chronic angle closure glaucoma. The patients were divided into two groups.
