Insights
This case report details iris implantation cysts appearing 24 years post-penetrating keratoplasty. These rare, benign cysts were diagnosed via clinical exam and Ultrasound Biomicroscopy (UBM), requiring no intervention.
Area of Science:
- Ophthalmology
- Surgical Pathology
Background:
- Iris implantation cysts are rare, benign growths.
- They arise from displaced epithelial cells within the iris stroma.
- Can be congenital or secondary to ocular trauma or surgery.
Purpose:
To report a case of iris implantation cysts occurring 24 years after penetrating keratoplasty and its management.
Observations:
A 60-year-old man was referred for diagnosis and management of white iris masses of the right eye. He had undergone bilateral penetrating keratoplasty 24 years before without complication. The clinical findings were suggestive of iris implantation cysts and Ultrasound Biomicroscopy (UBM) and anterior-segment optical coherence tomography confirmed the diagnosis. The patient did not develop any ocular complications from the cysts after one-year follow-up from the diagnosis of iris implantation cysts.
Conclusions And Importance:
Iris implantation cysts are rare benign tumors that develop after the ectopic implantation of epithelial cells within the iris stroma. They can be congenital or secondary to penetrating trauma or surgery. Their diagnosis relies on clinical examination and UBM. In case of intraocular complications, treatment may be required, otherwise observational follow-up is appropriate.
