Management of canalicular laceration.

Although canalicular injuries are relatively common, controversy persists regarding indications for repair and the surgical methods that should be employed. In this review, these various treatment philosophies and techniques are analyzed in an historical and a contemporary context. The surgical anatomy, epidemiology and clinical presentation of canalicular injuries are discussed. Inconsistencies in current nomenclature regarding the surgical anatomy of canalicular lacerations are analyzed. Recent studies of lacrimal drainage in systems with monocanalicular obstruction are cited. Various surgical techniques in the repair of canalicular injuries are reviewed, including methods of identifying the medial lacerated lacrimal passages and the various lacrimal stents that have been used. The current popularity of silicone tubing as a lacrimal stent is reviewed. The various methods of stent placement and fixation are systematically categorized. Case series of canalicular repair reported in the literature are reviewed, and the results and complications are compared.

Orbital lymphoma associated with acquired immune deficiency syndrome (AIDS).

A new case of AIDS-associated, small noncleaved cell (Burkitt's) lymphoma that presented as an orbital mass is described. Extraocular muscle involvement was documented by computed tomography and confirmed by orbital biopsy. Extensive abdominal involvement was subsequently diagnosed and this caused the patient's death only 15 days after the initial consultation and orbital biopsy. A literature review discloses only eight previous case reports of AIDS-associated non-Hodgkin's lymphoma (NHL) involving the orbit: two cases of Burkitt's type and six cases of large cell immunoblastic type. Three additional cases of orbital NHL can be found among larger series of AIDS cases. Affected patients are uniformly young adult males with a history of homosexuality and/or IV drug abuse. Variations in clinical presentation are discussed. Although the morphology of the histopathologic specimen in our case was consistent with a high-grade, small noncleaved cell NHL, flow cytometry revealed an atypical immunophenotype for Burkitt's lymphoma in that CD20 and immunoglobulin light chain antigens were not expressed. Morphologic classification and immunophenotypic characteristics of AIDS-associated NHLs are discussed.

Early descriptions of Horner's muscle and the lacrimal pump.

Horner's muscle (musculus orbicularis oculi pars lacrimalis or tensor tarsi) was first discovered by the French anatomist and surgeon, Jacques-François-Marie Duverney. In 1730 his student, Johann Caspar Schobinger, gave priority to Duverney and postulated muscular aid in an active drainage of tears. In 1745 Duverney first published his own anatomic description and the first illustration of this muscle. Credit for J.-F.-M. Duverney's discovery has often been erroneously given to his older brother, Joseph-Guichard Duverney. Subsequent anatomic descriptions by Johann Rosenmüller, William Horner, and others also included hypotheses about the physiology of a lacrimal pump. More recent theories about a lacrimal pump, such as those of Adler, Jones, Doane, and others, have their origins in these earlier writings.
