RESUMO
Although acute anterior uveitis has been noted in children with inflammatory bowel disease, it has not been appreciated in the absence of ocular symptoms. To determine the presence of asymptomatic uveitis, slit-lamp examinations were performed in 19 children with granulomatous bowel disease and seven with ulcerative colitis. In the former group, six had uveitis, while no abnormalities were noted in those with ulcerative colitis. Abnormalities consisted of cells and flare in the anterior chamber. In the group with asymptomatic uveitis, all were male, three were black, and all had colonic involvement. No positive correlations were noted between the presence of uveitis and bowel symptoms, duration of illness, extraintestinal manifestations, or specific treatment regimens. None of the six children with uveitis had evidence of spondylitis, and five were HLA-B27-negative. Repeated eye examinations six to 12 months later disclosed no evidence of uveitis in four of five children and improvement in the remaining child. These data suggest that asymptomatic transient uveitis is common in children with granulomatous bowel disease, but progression to severe adult uveal disease remains unclear.

Unilateral optic nerve transection without damage to the intraocular circulation was performed on thirteen cats. Fluorescein angiograms, trypsin digestion, and histologic preparation of the retinas were carried out. No changes in the retinal circulation and angioarchitecture were observed. These findings were compared to those reported in humans with comparable optic nerve lesions. We conclude that optic nerve transection does not cause retinal vascular alteration and this fact may be of pertinence to posterior ocular damage in glaucoma.
