THE PURPOSE of this paper is to call attention to an isolated sign—congestion of the upper quadrant of the bulbar conjunctiva without other ocular involvement. Congestion of the bulbar conjunctiva is a common sign in most diseases of the anterior segment. Congestion only in one sector serves as a guide to a pathological process in the particular sector. Among such typical conditions are phlyctenular conjunctivitis and keratitis, keratitis rosacea, early interstitial keratitis and episcleritis.
I have observed a number of patients with congestion of the bulbar conjunctiva localized to the upper quadrant only. The condition did not fit any of the known ocular diseases with sector-like congestion of the bulbar conjunctiva of a local or general cause. Altogether, 20 such patients have been observed, and its incidence is estimated as 1 in 1,500 patients with ophthalmic disease. The age of the affected persons, eight men and 12 women, ranged from
