—Dr. Levene has performed a service by presenting a series of cases of primary malignant glaucoma in his paper titled "A New Concept of Malignant Glaucoma," which was published in the Archives 87:497-506, 1972). The author redefined malignant glaucoma as a distinct type of angle closure with a forward movement of the lens and a direct closure of the angle occurring with or without glaucoma surgery. The term direct lens block angle closure is suggested to differentiate it from the more common pupillary block angle closure mechanism. The two types share common factors in their pathogenesis with the essential difference determined by the degree of the forward movement of the lens.I should like to point out that an analogous concept was advanced earlier and published in the Russian ophthalmic literature. As the latter is not well known in the West, some extracts of it are
