Impact of accommodative insufficiency and accommodative/vergence therapy on ciliary muscle thickness in the eye.

Purpose: Recent evidence suggests that the ciliary muscle apical fibres are most responsive to accommodative load; however, the structure of the ciliary muscle in individuals with accommodative insufficiency is unknown. This study examined ciliary muscle structure in individuals with accommodative insufficiency (AI). We also determined the response of the ciliary muscle to accommodative/vergence therapy and increasing accommodative demands to investigate the muscle's responsiveness to workload.

Sera of patients with rheumatoid arthritis contain antibodies to recombinant human T-lymphotrophic virus type I/II envelope glycoprotein p21.

A possible retroviral etiology for rheumatoid arthritis (RA) has been raised by results of recent studies. Therefore, we examined sera of patients with RA, including those with coexisting Felty's syndrome or leukemia of large granular lymphocytes, for the presence of antibodies to retroviral proteins of human T-lymphotrophic virus type I and type II (HTLV-I/II). Reactivity to recombinant HTLV-I envelope protein rgp21 alone was the primary pattern observed.
