Precis: This study is the first to report micropulse transscleral cyclophotocoagulation (MP-TSCPC) use in only good vision patients. MP-TSCPC significantly reduced intraocular pressure (IOP) and glaucoma medication use without any significant reduction in visual acuity at every postoperative follow-up point. Purpose: To evaluate outcomes of MP-TSCPC in eyes with baseline best-corrected visual acuity (BCVA) of ≥20/60. Methods: A retrospective review of patients who underwent MP-TSCPC at Mayo Clinic and Ross Eye Institute from July 2016 to August 2017 with BCVA of ≥20/60, and a minimum of 3 months follow-up. Results: A total of 61 eyes of 46 patients (68.80±17.12 y) underwent MP-TSCPC with a mean follow-up of 10.2±3.1 months. Mean IOP and mean number of glaucoma medications used were significantly reduced from baseline at every follow-up time point (P<0.0001). At month 12, mean IOP was reduced 40.2% from baseline with 85.4% of the patients having an IOP reduction of ≥20%, and mean glaucoma medication use reduced by 0.82±0.53 with 79.6% of the patients having a reduction of ≥1 medication. There was no significant reduction in BCVA from baseline at any follow-up point (P>0.05), except for 10 eyes with a vision loss of ≥2 lines and 5 out of 10 eyes had cataract progression. The probability of complete success (IOP range, 6 to 21 mm Hg or ≥20% IOP reduction; BCVA loss ≤2 lines, no reoperation for glaucoma) was 74.14%, 83.61%, 84.21%, and 75.0% at months 1, 3, 6, 12, respectively. The probability of qualified success (above criteria for IOP, no reoperation and BCVA loss >2 lines) was 81.03%, 91.80%, 94.74%, and 93.75% at months 1, 3, 6, 12, respectively. Conclusions: MP-TSCPC should be considered earlier in the management of glaucoma and can possibly be offered as an alternative to incisional glaucoma surgeries.

Purpose To report a case of post-operative endophthalmitis following combined cataract extraction and minimally invasive glaucoma surgery with placement of the iStent drainage device. Observation An 87-year-old woman with a nuclear sclerotic cataract and primary open angle glaucoma underwent elective phacoemulsification cataract extraction with iStent placement. Surgery was complicated only by the inability to properly place the second iStent despite several attempts. At 4 days post-operatively she was diagnosed with endophthalmitis. Despite the prompt intravitreal injections of broad spectrum antibiotics, she lost all perception of light. Cultures of anterior chamber aspirates failed to identify a causative organism. Conclusion and importance In what we believe to be the first report of endophthalmitis associated with placement of the iStent, complete loss of vision occurred. Surgeons need to be aware that iStent placement may be complicated by severe endophthalmitis.

Purpose This lecture will focus on preoperative examination, IOP changes and postoperative considerations, identifying the patients at higher risk for developing glaucoma and selecting an appropriate and personalized approach. Conclusion Most refractive surgeries are performed between the 3th and the 5th decade of a patients’ life. The prevalence of glaucoma increases with age and the life duration expectancy increases with progress in medicine. Although myopia and increasing age are known risk factors for developing glaucoma, it is impossible to predict which patients undergoing refractive surgery will develop glaucoma later in their life.
