The ocular symptom is the most important and the most disabling of the three major components of Behcet's disease. Its relative frequency has been reported to be as high as 70% to 85% in patients with the disease.
In this paper a survey of 23 cases is presented in order to establish the contribution of the ocular symptom in the diagnosis of the disease. The study revealed a surprisingly low incidence of eye symptoms among these cases (22%). The diagnosis of the disease in these cases was based mainly on symptoms other than the ophthalmological ones.
The only explanation we can offer for their infrequency is that we may be dealing with a selective patient population with a relatively short course of the disease. The ocular symptom is usually a late manifestation and could develop in due time.
