[Glaucoma drainage implants].

Introduction: The number of available glaucoma drainage implants has increased in recent years and now offers additional therapeutic opportunities in refractory glaucoma patients.

Methods: In drainage surgery two different functional principles are practised. The most commonly used implants (Ahmed, Krupin, Schocket, Molteno, Baerveldt) drain ocular fluid via a silicone tube into an episcleral reservoir.

Evaluation of nine candidate genes in patients with normal tension glaucoma: a case control study.

Background: Normal tension glaucoma is a major subtype of glaucoma, associated with intraocular pressures that are within the statistically normal range of the population. Monogenic forms following classical inheritance patterns are rare in this glaucoma subtype. Instead, multigenic inheritance is proposed for the majority of cases.

An extremely rare type of injury is presented: unintentional traumatic self-enucleation.

[Protein kinase C isoforms in corneal epithelium and endothelium].

Background: Protein kinase C (PKC) plays a key role in cell metabolism. Three subgroups and 12 isoforms have been isolated so far, catalysing specific functions in cell metabolism. The demonstration of PKC subtypes in corneal tissue has been inconsistent.

[Effect of timolol on central corneal thickness and endothelial cell density].

Background: The measurement of corneal thickness plays an increasing role in glaucoma screening and diagnosis. The influence of a variety of drugs on corneal thickness is well established. Especially for antiglaucomateous drugs this effect seems to be important.
