DISLOCATION OF THE GLAND has been met with in a few instances as a result of trauma, and in a very few in which the prolapse was congenital. In other rare instances it was spontaneous in origin.
Case of traumatic prolapse of lacrymal gland in 2 'A-year-old-boy due to fall on sharp stones; excision; no perceptible difference in moistening of eyes or flow of tears, confirming de Wecker's theory concerning emotional lacrymation. Hal tenhoff (Ann. d'Ocul., _May, '95).
Case of infant who fell and ruptured the external orbital soft tissues, dislo cating the lacryrnal gland. The hernia was reduced and the skin sutured. The function of the organ was not disturbed.
Bistis (Ann. d'Oculist., Dec., '95).
Trealment.—Extirpation of the gland is indicated in cases of neoplasms and extreme hypertrophy, or where there is obstinate stillicidium which cannot be controlled in any other way. This is accomplished by removing the gland, either directly through a skin incision made over the gland, or by an incision through the conjunctiva after exposure of the cul-de-sac, by division of the ex ternal canthus. The latter procedure is the one usually employed, as the ptosis which is apt to follow the first men tioned, due to injury of the levator, is L avoided, and the resultant scar is much less conspicuous.
In treatment of catarrhal lacrynull ob structions with epiphora, ablation of the palpebral portion of the lacryrnal gland advised if symptoms persist after the ordinary treatment has secured a per meability of the lacrymal passages. Ter
son (Recueil d'Ophtal., May, '91).
In case of hernia of the lacrymal gland, produced by traumatism, protruding portion removed without interfering with the function of the gland. Panter (Omaha Clinic, June, '92).
The removal of the lacrymal gland is a procedure demanding consideration in the treatment of simple or complicated epiphora, and of those instances which resist ordinary means. It is an operation which should be held in reserve and as a last resource. Palpebral removal is an operation of choice, suitable for simple and for the majority of complicated cases; hereas orbital removal is an operation of necessity. True (Archives d'Ophtal., May, '93).
Three cases of tumor of the lacrymal gland. The only operative procedure indicated in the second stage of the dis ease is the horseshoe-incision, made suffi ciently far from the orbital rim to avoid injury of the frontal nerves. Dianoux (Ann. d'Ocul., Aug., '94).
Excretory Apparatus, Diseases of the.
In contradistinction to diseases of the secretory portion of the lacrymal appa ratus, diseases of the excretory portion are of very frequent occurrence and are all characterized by the common and an noying symptom of tears flowing over the cheek.
