Periodic episodes of scleral hyperemia

Introduction Periodic episcleitis is also known as transient episcleritis. Most occur in women's menstrual period. The scleral surface and the bulbar conjunctiva of the lesion were diffusely congested and edematous, and were purple-red. It is a periodic episode, each episode is short-lived, and the constant is small or several days. Recurrence is not limited to one eye or the same site. The anterior sclera area usually occurs, and no localized nodules are formed. At present, the surface scleritis is still unclear, and one third of it may be associated with erythema, acne, gout, infection or collagen vascular disease.

Periodic superficial scleritis is a periodic episode with an interval of 1 to 3, and its onset is sudden, lasting from 1 day to several days. The scleral surface and the conjunctiva of the lesion were diffusely congested and edematous with a purplish red appearance. Lighter, showing mild pain and burning sensation, sometimes accompanied by neurovascular edema of the eyelids, and lack of vision. Occasionally, the pupil sphincter and ciliary muscle spasm occur, causing pupil dilation and sexual myopia. Women have more episodes, but the parts are not fixed.

Differential diagnosis

Should be differentiated from conjunctival hyperemia and scleral congestion:

(1) The blood vessels of the conjunctiva can be promoted. In conjunctivitis, the congestion is diffuse and often accompanied by secretions; while the superficial scleral vessels are relatively immobile, and the superficial scleritis is confined in the area from the limbus to the rectus attachment point. The conjunctiva is not involved, and the congested blood vessels are radially vertical and extend from the limbus.

(2) Congestion and edema of superficial scleritis is confined to the surface of the sclera, not to the lower sclera, and is identifiable by the slit lamp beam. The congestion is mostly dark red, and the blood vessels quickly turn white after the adrenaline drops, while the deeper scleritis is hyperemia, which is easy to fade after dropping adrenaline.
