Uveitis in leukemia is mainly a recurrent iritis, or retinal vasculitis, caused by leukemia. This type of disease can cause photophobia, tearing, eye redness and pain, floaters in front of the eyes, loss of vision, and it causes a tendency of relapse-remission-relapse of uveitis, which gradually worsens. Ophthalmologic examination may reveal cells in the anterior chamber, cells in the vitreous, damage to the retinal vessels in the fundus, hemorrhages in the fundus, and occlusive vasculitis.
