Purpose: The Aurolab® aqueous drainage implant is a low-cost alternative to the Baerveldt glaucoma implant. The aim of this study was to test the hypothesis that the two implants are comparable in terms of surgical success and safety. Methods: We conducted a retrospective case-control study of Aurolab aqueous drainage implant done at our institution from May 2015 and May 2017. Twenty-five consecutive patients who received an Aurolab aqueous drainage implant were matched by age and diagnosis to patients who received a Baerveldt glaucoma implant. Data were collected pre-operative and post-operative visits, including visual acuity and intraocular pressure, number of medications, and complications. Surgical success was defined as intraocular pressure between 5 and 21 mmHg with a minimum 20% reduction from baseline, without loss of light perception or the need for further glaucoma surgery. Cox regression analysis was used to predict factors associated with surgical success. Results: The median (interquartile range, IQR) intraocular pressure at 1 year was 16.0 (8.0) mmHg for the Baerveldt glaucoma implant and 13.0 (8.0) mmHg for the Aurolab aqueous drainage implant, p = 0.38. Success (mean ± SE) at 1 year for the intraocular pressure >21-mmHg failure criterion was 65% ± 15% for the Baerveldt glaucoma implant and 79% ± 11% for the Aurolab aqueous drainage implant (p = 0.80). The frequency of complications listed was similar for the two groups (Fisher’s exact p = 0.71). In the Cox regression, the type of implant was not found to be associated with surgical success. Conclusions: Our preliminary results suggest that the Aurolab aqueous drainage implant is comparable to the Baerveldt glaucoma implant. Further long-term data in a larger population are needed to confirm these findings.
Marcus Gunn jaw-winking syndrome (MGJWS) is a rare form of congenital blepharoptosis and one of the congenital cranial dysinnervation disorders (CCDD). In addition, morning glory disc anomaly (MGDA) is a congenital optic disc anomaly of unknown etiology. The present report is the first to describe an association between MGJWS and MGDA in an otherwise healthy 7-year-old boy. He also had counting finger vision, anisometropia, esotropia, and monocular elevation deficiency in the same eye. In the literature, both MGJWS and MGDA have been reported to be associated with Duane retraction syndrome, a form of CCDD.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
