Summary

Delayed suprachoroidal hemorrhage is a risk after glaucoma surgery, particularly with anterior chamber tube drainage. Avoiding post-operative hypotony is crucial in high-risk eyes to prevent this complication.

Area of Science:

  • Ophthalmology
  • Surgical Complications
  • Glaucoma Surgery

Background:

  • Delayed suprachoroidal hemorrhage is a rare but serious complication following intraocular surgeries.
  • Glaucoma surgeries like trabeculectomy and anterior chamber tube drainage aim to reduce intraocular pressure but carry inherent risks.

Purpose of the Study:

  • To investigate the incidence and risk factors of delayed suprachoroidal hemorrhage after glaucoma surgery.
  • To compare the risk of hemorrhage between trabeculectomy and anterior chamber tube drainage procedures.

Main Methods:

  • Retrospective analysis of 432 consecutive cases undergoing trabeculectomy or anterior chamber tube drainage.
  • Identification of factors associated with delayed suprachoroidal hemorrhage, including patient demographics, ocular characteristics, and surgical procedures.

Main Results:

  • Delayed suprachoroidal hemorrhage occurred in 13 eyes (3%).
  • Aphakia and prior vitrectomy were identified as significant risk factors for hemorrhage.
  • Anterior chamber tube drainage was associated with a higher incidence of hemorrhage compared to trabeculectomy.

Conclusions:

  • Aphakia and vitrectomy increase the risk of delayed suprachoroidal hemorrhage after glaucoma surgery.
  • Anterior chamber tube drainage may pose a higher risk than trabeculectomy, potentially due to more complex pre-operative conditions and greater pressure fluctuations.
  • Preventing post-operative hypotony is essential in high-risk eyes undergoing these procedures.
