Combined Left Central Retinal Artery Occlusion and Bilateral Anterior Ischemic Optic Neuritis: A Rare Presentation of Giant Cell Arteritis.

Giant cell arteritis, a large vessel vasculitis is characterized by headache, visual impairment, constitutional symptoms, and increased inflammatory markers. Visual involvement in giant cell arteritis ranges from amaurosis fugax to permanent visual loss, and extensive bilateral visual impairment is a rare presentation. We hereby report a case of combined left central retinal artery occlusion and bilateral anterior ischemic optic neuritis in a patient who poorly responded to standard corticosteroid therapy.

Emerging scrub typhus infection in the northern region of Sri Lanka.

Background: There is an increasing trend in rickettsioses or typhus fevers in the island of Sri Lanka. The seroepidemiological mapping previously published did not include the northern region of the island. This study was conducted to demonstrate the presence of scrub typhus (ST) and to characterise the clinical presentation of ST in this region.
