Complications following ophthalmic regional anaesthesia are rare but are reported during both needle (intraconal and extraconal blocks) and blunt cannula (sub-Tenon's block) techniques. At present there is no perfect technique of ophthalmic regional anaesthesia. This article reports on the complications, treatment and prevention of commonly used ophthalmic regional blocks. Thorough knowledge of the measures required to deal with complications when they occur are of paramount importance for safe clinical practice.

Comparative Study
Pentoxifylline decreases up-regulated nuclear factor kappa B activation and cytokine production in the rat retina following transient ischemia.
To investigate whether pentoxifylline (PTX) could influence the increased cytokine gene expression in the retina flowing transient ischemia, and if so, whether it acts through the modulation of nuclear factor kappa B (NF-kappaB) activation. ⋯ PTX decreased the up-regulated activation of NF-kappaB and the expression of proinflammatory cytokines, TNF-alpha and IL-1beta in rat retinas following ischemia/reperfusion. This may contribute to significantly reduce the loss of overall retinal thickness and thinning of inner retinal layers.

Alkali burns of the eye: effect of immediate copious irrigation with tap water on their severity.
To examine the effect of immediate irrigation on ocular alkali burn. ⋯ Immediate copious irrigation with tap water reduced the severity in alkali burns of the eye and shortened the healing time.

Randomized Controlled Trial
Pain relief after pterygium surgery with viscous lidocaine.
The aim of the current study is to investigate the efficacy of lidocaine 2% gel for the control of pain experienced after pterygium surgery. ⋯ We conclude that topical lidocaine gel is an effective and safe anesthetic agent for the control of pain experienced shortly after pterygium surgery.
