To evaluate the spectrum of glaucoma surgery undertaken among members of the Spanish Glaucoma Society (SEG).A 10 question web-based anonimous survey was mailed through the Annals of the Spanish Glaucoma Society to all its members on January, February and July 2019 to determine their preferred surgical approach.Age, type of Glaucoma, surgery undertaken, type of anti-scarring strategy and prothesis introduced for the last 10 surgeries since the survey was received. The surgeon experience was registered in years of practice.A total of 97 SEG members across the country answered the survey. Sixty-two (63.4%) responders had more than 10 years of experience. Primary open angle glaucoma was the most frequent type of glaucoma (60.6%). The most popular surgery was deep-sclerectomy (37.3%) followed by trabeculectomy (17,6%) and the collagen microshunt (XEN® Allergan Inc., Irvine, CA) (14.1%). Glaucoma drainage device (GDD) was used in 10.5% of the cases. Up to 21.7% of surgeries were reinterventions, where GDD was used in 27.3% and trabeculectomy in 20.3% of the cases. Glaucoma surgery was combined with phacoemulsification in 47.3% of the eyes. Mitomycin C (MMC) was used in 54,8% of the cases, collagen matrix (Ologen®, Aeon Astron Corporation, Taipei, Taiwan) was used alone in 8.2% of the cases and in 13,7% combined with MMC. MMC was used in a soaked sponge in 79% of cases (concentrations of 0.02% in 99% and 0.04% in 1%) and in 21% of cases MMC was injected subconjunctivally (concentrations of 0,01% in 81% and 0.02% in 19%).Although the glaucoma surgeon performs a wide range of surgical techniques, deep sclerectomy remains the most widely used surgical technique in Spain. Combined cataract and glaucoma surgery is performed almost in half of the patients and MMC is the most frequently selected antifibrotic agent, alone or combined with collagen matrix. The new minimal invasive surgical techniques represent the 20% of the total. |
