Implantation of the iris claw intraocular lens in the retropupillary position is a useful technique for correction of aphakic eyes with sufficient iris support, avoiding the corneal complications of an anterior chamber intraocular lens and the surgical challenge of a sutured posterior chamber intraocular lens.

Reduced contrast sensitivity had a marked effect on the speed but not the accuracy of performance on commonly used cognitive tests, even in young individuals; the implications of these findings are discussed.

A previously healthy 48-year-old man presented with a 1-week history of migrating polyarthropathy preceded by a viral illness, dysuria and bilateral red eyes. Ocular examination revealed anterior and interstitial stromal keratitis. He was systemically well but had raised erythrocyte sedimentation rate and C reactive protein and was positive for human leucocyte antigen B27 on extensive infective, rheumatological and autoimmune investigations. Although the exact triggering pathogen was not identified, clinical findings were consistent with reactive arthritis. Bilateral interstitial keratitis is a rare manifestation of reactive arthritis which, along with the anterior stromal keratitis, responded well to topical prednisolone sodium phosphate 0.5%. Systemic joint symptoms improved on oral sulfasalazine, non-steroid anti-inflammatory agent and low-dose prednisolone.
