ABSTRACT
Purpose: To evaluate the safety and efficacy of ultrasound cycloplasty in eyes with primary or secondary open?angle glaucoma, not amenable to adequate control of intra?ocular pressure (IOP) with medical treatment. Methods: Prospective interventional cohort study of 28 eyes of 28 subjects in a tertiary eye care centre in India in patients with open?angle glaucoma. All enrolled eyes underwent ultrasound cycloplasty with the second?generation probe with six shots of 8 s each, operated by a single surgeon between November 2018 and January 2020. They were followed up for a period of 12 months. The primary treatment outcome was IOP and the secondary outcomes were vision and postoperative complications. Results: A total of 28 eyes of 28 patients were studied, and the mean age was 63.82 ± 6.46 years. Primary open?angle glaucoma (75%) was the most common etiology. There was significant reduction in IOP from the baseline (24.93 ± 4.27 mmHg) to the postoperative value (15.82 ± 3.14 mmHg) at the end of 12 months (P < 0.00001). Mean reduction in IOP was 9.14 ± 4.09 mmHg at 12 months (36.66%). Number of ocular hypotensives reduced significantly from baseline (3.32 ± 0.47) to 12?month postoperative follow?up (0.68 ± 0.74) (P < 0.00001). Qualified success was achieved in 89.28% eyes. No major complications were noted. Conclusion: Ultrasound cycloplasty is found to be effective and safe in eyes with open?angle glaucoma because of the primary or secondary etiology, being more effective in the former
ABSTRACT
Purpose: To comparatively evaluate in Indian eyes with coexisting cataract and primary open?angle glaucoma the outcome of mitomycin C (MMC) and Ologen implant as adjunctives in combined phacoemulsification with trabeculectomy. Methods: Eyes with primary open?angle glaucoma that underwent trabeculectomy and phacoemulsification with IOL implantation with either MMC application or Ologen implant between June 2019 and February 2020 were followed up for 12 months. Thirty?four eyes of 34 participants were studied. The primary outcome was intraocular pressure (IOP), and the secondary outcomes were the number of ocular hypotensives, best distance visual acuity (BDVA), and bleb morphology. Results: In 16 eyes treated with MMC and 18 eyes treated with Ologen implant, it was observed that the mean postoperative IOP (14.62 � 2.89 mm Hg with MMC and 14.56 � 4.14 mm Hg with Ologen implant) was not significantly different in both groups (P = 0.47). Number of ocular hypotensives and BDVA were also comparable between the two groups. However, bleb morphology was better with Ologen implantation. One eye in the MMC group developed hypotony which was conservatively managed. Conclusion: MMC and Ologen are both effective adjunctives in combined phaco?trabeculectomy. However, the Ologen implant provides better bleb health and safety
