OPHTHALMOLOGICAL MANIFESTATIONS IN BEHCET'S DISEASE, COMPUTER ANALYSIS OF 1074 CASES.


Abstract: Behcet's Disease (BD) is rather frequent in Iran. Near 200 new cases are seen every year, and this rate is going up every year. Oph­thalmological manifestations are frequent (71%). Anterior uveitis (AU) is seen in 63% of patients. It is characterized by flare and cells in the anterior chamber. Hypopion, the classic lesion of the anterior chamber is transient and rarely seen in ophthalmologic examination. The AU progresses by successive attacks and remissions. Posterior synechia, cataract and glaucoma are complications of AU. Posterior uveitis (PU) is seen in 53% of patients. It is characterized by cells and floater in the vitreous body. PU also progresses by successive attacks and remis­sions, but unlike AU, remissions are incom­plete. Therefore from one attack to another, lesions become cumulative. Organization of the vitreous body and hemorrhage are frequent complications of PU. Retinal vasculitis (RV) is seen in 40% of patients. It is charac­terized by periarteritis, periphlebitis, retinitis, retrobulbar neuritis and papil­litis. RV also progresses by successive at­tacks, but remissions are rare. PU and RV progress rapidly toward sever loss of vision and blindness, if not treated.
