Chromic Cyclitis, Pars Planitis

ABSTRACT

This disease entity, first described under the desgnation of cyclitis by Ernst Fuchs, has received renewed attention in the recenet years, having been described as peripheral uveitis, pars planitis, and cyclitis with peripheral chorioretinitis. Apparently new ophthalmoscopic findings have caused some obserbers to believe they are dealing with a new entity, because indirect ophthalmoscopy with scleral depression shows exudation in the pars plana region in severe or advanced cases. In this entity, The following characteristic findings are noted, occurring bilaterally, inflammatory cells in anterior vitreous, slight flare and cells in the anterior chamber in come instances, dilated veins, and snowball deposition of inflammatory cells over the pare plana and ora serrata, seen with scleral depression and indirect ophthalmoscope extending over the lower 180 degrees. Cystoid macular degeneration are demonstrated with fluorescein angiography in over half the caces; papilledema may occur in late cases; and peripheral retinal perivascular sheathing is noted in long standing cases.
