Overfiltering Bleb en Route to Annular Ciliochoroidal Effusion

Area of Science:

• Ophthalmology
• Glaucoma Surgery
• Choroidal Effusions

Background:

• Trabeculectomy is a common surgical procedure for glaucoma.
• Complications can arise, including those affecting the anterior chamber and intraocular pressure.
• Distinguishing between different types of hypotony is critical for appropriate management.

Observation:

• A case of annular ciliochoroidal effusion mimicking aqueous misdirection post-combined glaucoma and cataract surgery is presented.
• The patient exhibited an overfiltering bleb, hypotony, and a uniformly shallow anterior chamber.
• Ultrasound biomicroscopy was key in confirming the diagnosis of ciliochoroidal effusion.

Findings:

• Annular ciliochoroidal effusion can present with clinical signs similar to aqueous misdirection.
• Hypotony and shallow anterior chamber following glaucoma surgery warrant consideration of ciliochoroidal effusion.
• Medical management with cycloplegics (atropine) and steroids can be effective.

Implications:

• This case highlights the importance of considering ciliochoroidal effusion in the differential diagnosis of hypotony post-glaucoma surgery.
• Accurate diagnosis using tools like ultrasound biomicroscopy is essential.
• Prompt management can prevent further visual complications.
