Purpose: The purpose of the study was to measure the change in intraocular pressure (IOP) after micropulse laser trabeculoplasty (MLT) and to evaluate subgroups based on initial IOP and severity of glaucoma.
Methods: This was a retrospective study of 34 eyes that were treated with MLT. Follow-up measurements were obtained at 3 months. Paired -tests compared baseline to follow-up.
Results: IOP reduction approached significance ( = 0.055) for lower mean IOP from pre- to post-treatment. In the subset of those with baseline IOP >16, mean IOP was significantly lower ( = 0.001) from pretreatment (mean = 19.43, standard deviation [SD] = 2.48) to posttreatment (mean = 16.91, SD = 3.37). There were 34.8% (8/23) with a 20% reduction from baseline IOP. For patients with no glaucoma/early glaucoma, mean IOP was significantly lower ( = 0.003) from pretreatment (mean = 19.62, SD = 3.36) to posttreatment (mean = 16.62, SD = 3.01). In the subset of those with moderate/advanced glaucoma, there were no significant changes for mean IOP from pretreatment to posttreatment.
Conclusion: Patients with higher initial IOP and in the early stages of glaucoma were more likely to benefit from MLT in lowering IOP. A randomized clinical trial is necessary to confirm these preliminary findings. We recommend that clinicians should consider MLT in the management of early glaucoma and among those with IOP >16 mmHg.

Glaucoma is a leading cause of irreversible blindness, often associated with elevated intraocular pressure (IOP) due to trabecular meshwork (TM) dysfunction. Diabetes mellitus (DM) is recognized as a significant risk factor for glaucoma; however, the molecular mechanisms through which hyperglycemia affects TM function remain unclear. This study investigated the impact of high glucose on gene expression in human TM (HTM) cells to uncover pathways that contribute to TM dysfunction and glaucoma pathogenesis under diabetic conditions.

Purpose: To describe a case of central retinal artery occlusion following scleral buckling procedure combined with pneumoretinopexy in a patient with sickle cell (HbSC) retinopathy (SCR).
Methods: Scleral buckling procedure, combined with injection of 0.3 ml of 100% perfluoropropane (C3F8) gas in the vitreous, was performed without intra-operative complications under general anaesthesia as treatment of two separate macula-sparing rhegmatogenous retinal detachments secondary to round holes, involving superior and inferior retina respectively, in the right eye of a 26-year-old Afro-Caribbean female with sickle cell disease.

Article Synopsis
- The study examined how myopia affects the thickness and structure of retinal blood vessels using advanced imaging technology in 100 participants.
- The findings revealed that individuals with high myopia had significantly lower vessel density and thinner retinal layers, particularly noticeable in the superficial and nerve fiber layers.
- There was a noted correlation between certain ocular parameters, such as axial length to curvature radius ratio, and retinal thickness in non-high myopic eyes, while high myopic eyes showed less correlation in these aspects.
3D Finite Element Modeling of Femtosecond Laser Trabeculotomy.

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.
