We presented a case of a 54-year-old woman, who developed sarcoidosis uveitis while on treatment with the tumour necrosis factor α (TNFα) antagonist etanercept for rheumatoid arthritis. Her condition improved, but did not recover completely after the medication was stopped. After starting her on another TNFα antagonist, adalimumab, the uveitis recovered completely. Etanercept and adalimumab are from the same class of medication, but have different effects on other mediators and cells, which may explain these discrepancies.
We would like to present a case of branch retinal artery occlusion following uneventful phacoemulsification, possibly caused by sub-Tenon's anaesthesia. There were no predisposing general health problems. There are two possible mechanisms: (1) mechanical effect of the bolus anaesthetic; (2) pharmacologically mediated changes in the vascular calibre. The latter mechanism is much more probable, because of the vasoconstrictive properties of both medications used. This is the first reported case of branch retinal artery occlusion after sub-Tenon's anaesthesia with preservative-free medications.
A case of congenital vitreous cyst is presented. An optical coherence tomography scan has been performed, which has shown that the cyst is free floating and is multilobular. Its content was hyper-reflective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
