From Schlemmscanal to a point right beneath the conjunctiva, the anterior ciliary veins, v, v, run continuously throughthe sclera. Most scleral ruptures follow these cavities in the direction ab, so that the external orificeof the rupture lies some millimetres behind the limbus. More rarely the ruptures of the sclera passperpendicularly in the direction ac, or even run obliquely forward in the direction ad. Ruptures ofthe latter sort have usually but little length so that nothing but the iris prolapses and this only to aslight extent (Fig. 132), and the rupture itself does not become visible until the iris is excised (Fig. 133).These small ruptures almost always afford a good
