[Retinal and trabecular degeneration in glaucoma: new insights into pathogenesis and treatment].

Academic and industrial research has brought new insights into the pathogenesis of glaucoma, aiming at identifying and targeting specific mechanisms to improve our current therapeutic strategy. Retinal neurodegeneration is still the main focus, whether in terms of extrinsic factors such as neurotrophin deprivation, glutamate toxicity, vascular deficiency and neuro-inflammation from glial cells, or in terms of retinal ganglion cell intrinsic sensibility to proapoptotic signals. However, glaucoma is not solely a retinal disease but also involves retinal and trabecular meshwork degeneration, extending into and/or even originating from the brain.

[Fusobacterium nucleatum isolated from a patient presenting lachrymal canaliculitis].

A 68-year-old woman presented with a painless inflammation of the right superior eyelid that had started several weeks before. The clinical diagnosis concluded in canaliculitis and the solid concretions were surgically extracted from the superior canalicula. The anaerobic bacteria Fusobacterium nucleatum sp.

[Transcanalicular endodacryocystorhinostomy using Neodymium:YAG laser].

Unlabelled: We describe a new technique of dacryocystorhinostomy (DCR) and we present our first clinical cases. The principle of this technique is to create a fistula between the lacrimal sac and the nose with a quartz fibre advanced through a canaliculus and connected to a Neodymium:YAG.

Technique: An 800 microns outer diameter metallic pipe was inserted through a lacrimal canaliculus up to bone contact.
