Summary

This is the first reported case of bilateral iris tumors metastasized from prostate cancer. Conservative therapies, including radiation, effectively controlled these rare ocular metastases.

Ophthalmology. Glaucoma·2025

Area of Science:

  • Ophthalmology
  • Oncology

Background:

  • Metastases to the iris are uncommon, typically presenting unilaterally.
  • Prostate cancer metastasis to the iris has not been previously reported, especially in a bilateral presentation.

Observation:

  • A 71-year-old male with a history of prostate cancer and bone metastases developed bilateral iris tumors.
  • The tumors presented as gray-white masses causing iridocyclitis and secondary glaucoma.
  • External beam radiotherapy led to remarkable regression of the iris tumors.

Findings:

  • The case represents a rare instance of bilateral iris metastases originating from prostate cancer.
  • The ocular tumors responded well to conservative treatment, including radiotherapy.
  • This study documents the first known case of bilateral iris tumors secondary to prostate cancer.

Implications:

  • Highlights the potential for prostate cancer to metastasize to the iris bilaterally.
  • Demonstrates the efficacy of radiotherapy in managing rare ocular metastases.
  • Suggests the importance of ophthalmic examination in patients with advanced prostate cancer presenting with ocular symptoms.
