Surgical anatomy of the lacrimal fossa a prospective computed tomodensitometry scan analysis.

Purpose: To establish the accurate surgical anatomy of endonasal dacryocystorhinostomy (DCR) based on the radiological analysis of underlying bony structures.

Design: Prospective noncomparative observational case series study.

Participants: Fifty-nine patients with complete nasolacrimal stenosis underwent a computed tomodensitometry (CT) scan before endonasal DCR.

Testing ocular fluids in uveitis.

Infectious uveitis is a serious condition requiring rapid diagnosis and therapeutic management. Molecular tools, such as PCR and its variants, have significantly changed the diagnostic approach during the last 10 years. Presumed and empirical diagnosis should be excluded in the face of atypical clinical presentations, but also inadequate response to anti-inflammatory drugs.
