title: Endoscope-assisted goniosynechialysis combined with phacoemulsification and intraocular lens implantation to manage primary angle-closure glaucoma.
abstract: OBJECTIVE
  To describe and evaluate a new ophthalmic endoscope surgical technique combined with phacoemulsification and intraocular lens (IOL) implantation to treat goniosynechialysis and manage primary angle-closure glaucoma (PACG).
  
  
  METHODS
  Endoscope-assisted goniosynechialysis combined with phacoemulsification and IOL implantation was performed in 32 eyes of 29 patients with PACG. Regular follow-up was performed 1 week and 1 month, 3, and 6 months after surgery to assess complications, intraocular pressure (IOP), anterior chamber depth, visual acuity, and anterior chamber angle.
  
  
  RESULTS
  Preoperative mean IOP was 24.88±7.22mmHg with pharmacological treatment, and was 13.70±4.02, 13.06±3.74, 14.29±4.70, and 14.33±5.01mmHg 1 week, 1 month, 3 months, and 6 months after surgery, respectively. The postoperative decrease in IOP was significant (P<0.05). The rate for all eyes with IOP of 21mmHg or less was 93.8% (30 eyes) at the final visit without ocular hypotensive agents. The average preoperative anterior chamber depth was 1.60±0.64mm, and this value significantly increased to 2.72±0.62, 2.76±0.70, 2.73±0.68, and 2.74±0.71mm at 1 week, 1 month, 3 months, and 6 months, respectively. Visual acuity was improved in 28 eyes (87.5%) at 6 months postoperatively. The anterior chamber angle had increased in 25 eyes (78.1%) at the final visit; it was adhesive 90°-180° in 6 eyes, 180°-270° in only 1 eye. Two eyes exhibited minimal hyphema in the early postoperative period, but it could gradually be absorbed. Fibrinous reaction was observed in five eyes and spontaneously disappeared within 7 days. No shallow anterior chamber, iridodialysis, choroidal detachment, or malignant glaucoma was found in any eyes.
  
  
  CONCLUSIONS
  Endoscope-assisted goniosynechialysis combined with phacoemulsification and IOL implantation to manage PACG has several advantages, including optimized visualization, greater accuracy, and improved safety. Our results suggest that it has certain curative effects and clinical application value.
