[Fine-needle aspiration in an extremely late post-traumatic iris cyst]

Area of Science:

• Ophthalmology
• Ophthalmic Surgery

Background:

• Iris inclusion cysts can manifest years after ocular trauma or surgery.
• Delayed presentations pose diagnostic challenges in ophthalmology.

Observation:

• A 45-year-old woman presented with a three-week history of left eye pain, redness, and decreased visual acuity.
• Ultrasonic biomicroscopy revealed a serous iris cyst with an adjacent peripheral corneal leukoma.
• The cyst was presumed to be a sequela of remote penetrating ocular trauma.

Findings:

• Fine-needle aspiration and partial posterior synechiolysis were performed.
• The iris cyst resolved following the procedure.
• The patient experienced improvement in visual acuity.

Implications:

• Fine-needle aspiration is an effective diagnostic and therapeutic modality for iris inclusion cysts.
• Ocular trauma history is crucial for evaluating delayed-onset intraocular pathologies.
• Early diagnosis and intervention can prevent long-term visual impairment from iris cysts.
