[Clinical study of 12 cases of malignant non-Hodgkin's lymphoma of the orbital region].

Over an 8-year period in the Departments of Hematology, Ophthalmology and Internal Medicine of our hospital, 12 cases of orbital and adnexal malignant non-Hodgkin's lymphoma were reported. Diagnostic elements varied, including local tumefaction, watering eyes, uveitis, and unexplained, long-term fever. Nine patients had primary paraocular lymphomas involving either orbital structures, the lacrimal gland or the eyeball, but after appropriate staging, the disease was found to be disseminated in 5; the 3 other cases were secondary orbital lymphomas.

[Role of nasolacrimal intubation in the treatment of lacrimation caused by congenital lacrimal duct obstruction in infants].

We report a study of a series of 83 cases of congenital nasolacrimal duct obstruction treated with monocanaliculonasal or bicanaliculonasal silicone intubation. Efficacy, complications, as well as the duration of the placement of the probes were studied. The analysis of the various factors of this series (age of the infants at the time of intubation, duration and type of intubation, complications) demonstrated the superiority of short-term monocanaliculonasal intubation (about four weeks) compared to longer intubation.
