 AB    The human retroviruses, HTLV-I and HIV, are playing clinically important
       roles in a variety of ocular disorders, particularly in uveitis. Both
       viruses are integrated in the genome of infected T cells. HIV-I
       infection causes the death of the infected T cells, thereby affecting
       the host defence system and causing AIDS. Subsequent opportunistic
       infections of ocular tissues, such as CMV retinitis, are a serious
       problem in clinical ophthalmology all over the world. Another human
       retrovirus, HTLV-I, has been known as the causative agent of T cell
       malignancies (ATL and T cell lymphoma) and chronic myelopathy (HAM/TSP),
       and is now recognised as a causative agent for a specific type of
       intraocular inflammation characterised by vitreous opacities with mild
       iritis and mild retinal vasculitis (HTLV-I uveitis). The mechanism by
       which HTLV-I causes uveitis is still unknown, but our recent data
       suggest that it is most probably an immune mediated mechanism by
       activated CD4 T cells infected with the virus. HTLV-I uveitis,
       therefore, may implicate a significant role of retroviruses in
       autoimmune diseases and further the pathogenesis of diseases with
       infection/autoimmune overlap.
