Evaluating Collagen Cross-Linking (CCL) Treatment in Norway

The technique of corneal collagen cross-linking consists of photopolymerization of stromal fibers by combined action of a photosensitizing substance, riboflavin and ultraviolet type A rays (UVA) from a solid-state UVA Source. Photopolymerization increases the rigidity of corneal collagen and its resistance to keratectasia. It has been used to stop progression ...

Comparison of Efficacy of Two Groups of Glaucoma Drops (Xalatan vs.Cosopt) in Reducing Eye Pressure Following Laser (SLT)Treatment in the Management of Glaucoma.

Introduction Selective Laser Trabeculoplasty has been shown as a relatively safe and effective treatment modality for lowering IOP in various forms of open-angle glaucoma (Latina et al). It lowers IOP by increasing aqueous outflow through its effect at cellular level possibly either (1) through migration and phagocytosis of trabecular meshwork ...

Subconjunctival Bevacizumab to Prevent Bleb Failure After Glaucoma Filtration Surgery

Glaucoma Filtration Surgery (GFS) remains the definitive surgical management for elevated IOL uncontrolled by medical management. Bleb failure is a major factor limiting the longterm success of trabeculectomy surgery. Bleb failure involves vascularization with fibroblast migration and eventual scarring of the fistula tract. Vascular Endothelial Growth Factor (VEGF) is a ...
