Fig. 2From: Vanishing retinal arterial aneurysms with anti-tubercular treatment in a patient presenting with idiopathic retinal vasculitis, aneurysms, and neuroretinitisPositive results of multiplex polymerase chain reaction demonstrating positivity to tubercular antigens in the vitreous fluid. Band L1 represents 100-bp molecular marker; L2 is the positive control (asterisk indicates protein B (419Â bp), double asterisks indicate MPB64 (240Â bp), dagger indicates IS6110 (123Â bp)). Band L3 is the negative control. Bands L4, L5, and L6 represent the positive results obtained from the vitreous fluid of the patient described in the index caseBack to article page
