Vortex keratopathy is characterized by bilateral symmetrical superficial corneal deposits in a vortex pattern. It is the most common ocular finding among patients being treated with amiodarone. An unusual case of unilateral amiodarone vortex keratopathy in an elderly woman with corneal dysplasia in the second eye is presented. The pathophysiology of amiodarone keratopathy is explored, and a cause for the unilateral keratopathy in this patient proposed.

Anaesthesia techniques for cataract surgery: a survey of delegates to the Congress of the International Council of Ophthalmology, 2002.
Cataract surgery is performed using various regional, local, or topical anaesthetic techniques and agents and general anaesthesia. As there is continuous change in the popularity of these techniques, an estimate of current anaesthetic practices for cataract surgery around the world was derived. This allows comparison of techniques and practices internationally and may serve as a baseline for future surveys. ⋯ Although there is a single most frequent practice in the type of regional block employed for cataract surgery among the delegates, and general anaesthesia is seldom used, individual countries have very different results regarding the anaesthetic used and the role of the anaesthetist.

Infliximab for juvenile idiopathic arthritis-associated uveitis.
Infliximab is a murine-human recombinant antitumour necrosis factor monoclonal antibody recently introduced for the treatment of autoimmune diseases in which tumour necrosis factor is thought to be a key mediator. Its role in the treatment of juvenile idiopathic arthritis-associated uveitis is as yet undefined. ⋯ Infliximab may be a useful adjunct to the management of refractory juvenile idiopathic arthritis-associated uveitis. In our series it was associated with improved uveitis control and simplification of drug use as well as possibly improving safety of surgical intervention. This study suggests that its role is likely to be in conjunction with maintenance immunomodulatory treatment to provide more optimal disease control. Controlled studies are required to confirm its efficacy and safety, and the potential breadth of its use in uveitis and related disorders.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of the Tono-Pen and Goldmann tonometer for measuring intraocular pressure in patients with glaucoma.
To estimate agreement between measurement of intraocular pressure (IOP) by the Tono-Pen and by the Goldmann tonometer. The hypothesis tested was that the mean difference in measurements would be <-2 mmHg. ⋯ The Tono-Pen cannot replace the Goldmann tonometer in the sense that it will give the same readings of IOP. The accuracy of the Tono-Pen is increased, if at least two measurements are taken per eye and then averaged.

Randomized Controlled Trial Comparative Study Clinical TrialEffect of volume used in sub-Tenon's anaesthesia on efficacy and intraocular pressure: a randomized clinical trial of 3 mL versus 5 mL.
To compare the effect of volume used in sub-Tenon's anaesthesia on efficacy and intraocular pressure (IOP). ⋯ A 5 mL volume of anaesthetic provides akinesia superior to a 3 mL volume in sub-Tenon's anaesthesia for cataract surgery.
