ABSTRACT
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.Palavras-chave
