Proton beam therapy for the treatment of uveal melanoma in Scotland.

Background And Aims: In Scotland, uveal melanomas are primarily treated with eye-preserving modalities with a low primary enucleation rate. Proton beam therapy (PBT) is reserved for those not suitable for brachytherapy. The authors' aim was to review the outcome of Scottish patients undergoing treatment for uveal melanoma with PBT.

Presence of free radicals in intracameral agents commonly used during cataract surgery.

Background: Free radicals are known to cause cellular damage and are present in ophthalmic preparations. Corneal defence mechanisms are bypassed in intra-ocular surgery. We evaluated commonly used intracameral agents to ascertain the presence of free radicals and investigate the possibility of anterior segment and endothelial toxicity.
