    [Reprinted from the Royal London Ophthalmic Hospital Reports, Vol. XIII, Part 3.j PSEUDO-OLIOMA. By E. Treacher Collins. Curator of the Museum. * ■ That the diagnosis of glioma of the retina is still often attended with considerable difficulty is shown by the fact, that, during the four years from July, 1888, to July, 1892, of the 1,020 eyes which were excised at the Moorfields Hospital, 24 were removed because they were supposed to contain a glioma of the retina, and in 7 of these the pathological examination subsequently showed this not to be the case. These cases, in which the appearances in the eye simulate closely those of a true glioma of the retina, are termed pseudo-glioma, a term which, in that it implies no definite pathological condition, is a bad one, but is of considerable use clinically, because it includes three dis- tinct conditions of the eye, which, with our present know- ledge, are not only very difficult to differentiate from true glioma, but still more difficult to distinguish from one another. Defining pseudo-glioma, then, as any condition of the eye liable to be mistaken for true glioma, the term may be applied to three classes of cases— 1st. Those in which there is a persistence and thicken- ing of the posterior part of the foetal fibro-vascular sheath of the lens, or an atypical development of the anterior part of the vitreous, with or without a persistent hyaloid artery. 2nd. Cases in which large masses of tubercle occur in the choroid. 3rd. Cases in which there has been inflammatory effusion into the vitreous, following a retinitis and cyclitis, and in most cases accompanied by detachment of the retina. b
