Ciliary block glaucoma, often resistant to treatment, can occur when ophthalmic viscoelastic devices enter the vitreous. Vitrectomy effectively resolved a case caused by sodium chondroitin sulfate-sodium hyaluronate.

Area of Science:

  • Ophthalmology
  • Glaucoma Research
  • Surgical Complications

Background:

  • Ciliary block glaucoma, or malignant glaucoma, is characterized by aqueous misdirection into the vitreous.
  • This condition is notoriously difficult to manage with medical therapies and often necessitates surgical intervention, such as vitreous aspiration.

Observation:

  • A case of ciliary block glaucoma was identified.
  • The glaucoma was attributed to sodium chondroitin sulfate-sodium hyaluronate (Viscoat) inadvertently entering the vitreous cavity.
  • Access to the vitreous occurred via an undetected, small zonular dialysis.

Findings:

  • The use of sodium chondroitin sulfate-sodium hyaluronate (Viscoat) as an ophthalmic viscoelastic device was implicated in causing ciliary block glaucoma.
  • A small, unsuspected zonular dialysis served as the pathway for the Viscoat to enter the vitreous.

Implications:

  • This case highlights a rare but severe complication associated with ophthalmic viscoelastic devices.
  • Vitrectomy, performed through a peripheral iridectomy, proved to be a successful treatment for this refractory glaucoma.
  • Understanding potential routes of entry for intraocular substances is crucial for preventing and managing surgical complications.
