Circumferential trabeculotomy with an illuminated microcatheter in congenital glaucomas.

Purpose: To determine the safety and efficacy of circumferential trabeculotomy for congenital glaucomas using an illuminated microcatheter.

Methods: This was a retrospective chart study involving 11 eyes from 7 patients with primary or secondary congenital or juvenile glaucoma who underwent circumferential trabeculotomy performed with an illuminated microcatheter over a 2-year period. Data from eyes with 6 or more months of follow-up intraocular pressure (IOP) data were included in the analysis.

Does the maxillary division of the trigeminal nerve traverse the cavernous sinus? An anatomical study and review of the literature.

Aim: Many authors have included the V2 segment of the trigeminal nerve as a component of the cavernous sinus. However, many authorities have stated that this part of the fifth cranial nerve is not within this intracranial venous sinus.

Materials And Methods: To further elucidate this potentially important relationship, 10 fresh cadaveric heads underwent injection of the cavernous sinus with blue latex or a cresyl-violet solution.
