Advanced glaucoma surgery can lead to hypotony and choroidal detachment. Treatment with corticosteroids and cycloplegics improved outcomes, but timolol use caused recurrence in one case.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Surgical Complications

Background:

  • Primary open-angle glaucoma (POAG) management often involves surgical interventions like trabeculectomy and phacoemulsification.
  • Understanding potential complications following glaucoma surgery is crucial for patient care and outcomes.

Observation:

  • Three patients with advanced POAG experienced hypotony and choroidal detachment 2-3 months post-surgery.
  • Complications occurred after uncomplicated trabeculectomy (one patient) and phacoemulsification (two patients), with prior trabeculectomy in the latter two.
  • No wound or bleb leakage was identified, and patients were not on glaucoma medications pre-detachment.

Findings:

  • Topical corticosteroids and cycloplegic eyedrops led to significant clinical improvement in two patients within 2-6 weeks.

  • One patient experienced recurrent choroidal detachment after initiating timolol for elevated intraocular pressure (IOP).
  • Spontaneous resolution of detachment occurred upon timolol discontinuation.

    • Implications:

    • Hypotony and choroidal detachment are potential, albeit rare, complications of advanced glaucoma surgery.
    • Steroid and cycloplegic therapy can be effective in managing these post-surgical complications.
    • Caution is advised regarding beta-blocker use (e.g., timolol) in patients with a history of choroidal detachment, as it may precipitate recurrence.
