Cavernous-dural fistula with secondary angle-closure glaucoma

S J Talks1, J F Salmon, J S Elston

Summary

A rare case of angle-closure glaucoma caused by choroidal effusion in a patient with a cavernous-dural shunt is presented. Prompt surgical drainage of the effusion resolved the glaucoma, preventing permanent vision loss.

Area of Science:

  • Ophthalmology
  • Neurology
  • Vascular Surgery

Background:

  • Cavernous-dural shunts are abnormal connections between the cavernous sinus and meningeal arteries.
  • Angle-closure glaucoma is a serious condition characterized by increased intraocular pressure.
  • Choroidal effusions are collections of fluid in the choroid layer of the eye.

Observation:

  • A patient with a long-standing cavernous-dural shunt developed acute angle-closure glaucoma.
  • Imaging revealed a rapidly developing choroidal effusion secondary to partial thrombosis of the superior ophthalmic vein and cavernous sinus.

Findings:

  • The choroidal effusion was identified as the cause of the angle-closure glaucoma.
  • Surgical drainage of the choroidal effusion led to the resolution of glaucoma.

Implications:

  • This case highlights a rare but serious complication of cavernous-dural shunts.
  • Prompt surgical intervention for choroidal effusion can prevent permanent vision loss in glaucoma.
  • Understanding the venous drainage pathways is crucial in managing such complex vascular and ocular conditions.
