Haemarthrosis is an uncommon complication of anticoagulation therapy. Tranexamic acid (TXA) has a high clinical value for the treatment of bleeding due to fibrinolysis. ⋯ Intra-articular injection of TXA led to a cessation of haemarthrosis without any adverse event for 1 year. Intra-articular injection of TXA may be an effective treatment for warfarin-related haemarthrosis.

Case Reports
Transvenous sclerotherapy of a large symptomatic orbital venous varix using a microcatheter balloon and bleomycin.
An orbital venous varix is rare and can present with diplopia, proptosis, or hemorrhage. Treatment can be challenging, especially if the varix is in a posterior location within the orbit, since surgical exposure becomes difficult. A few case reports have been published describing transcatheter embolization of an orbital varix with coils, direct percutaneous injection of n-butyl cyanoacrylate glue, and the percutaneous injection of bleomycin. We present a case of a symptomatic orbital venous varix of the left inferior ophthalmic vein successfully treated with transvenous endovascular sclerotherapy using a microcatheter balloon and bleomycin.

Optic neuropathy due to cat scratch disease (CSD) is a rare occurrence associated with macular star formation and is characterised by sudden mostly unilateral painless loss of vision. The aetiological agent in CSD is Bartonella henselae. ⋯ Ocular bartonelosis is usually self-limited. A case of a man patient with neuroretinitis caused by B. henselae is reported.
