[Metastatic choroid tumors before and after radiation]
Summary
This study analyzes fundus photographs of choroidal metastases from various cancers. It details the appearance of these tumors and their response to treatments like radiation and cytostatics.
Area of Science:
- Ophthalmology
- Oncology
Background:
- Metastatic choroidal carcinoma is a significant ocular finding.
- Understanding its funduscopic appearance is crucial for diagnosis and management.
Observation:
- Fundus photographs of 20 patients with metastatic choroidal carcinoma were analyzed.
- Tumors presented as yellowish-grey, lobular, or solitary homogeneous areas.
- Mammary, bronchial, and uterine carcinomata were the primary sources.
Findings:
- Bilateral metastases occurred in 5 cases, predominantly affecting the left eye.
- Post-treatment scarring showed varied pigmentation changes, including depigmentation and irregular pigment displacement.
- Radiation therapy for uterine carcinoma metastasis caused necrosis of ocular tissues.
Implications:
- The study provides a detailed visual reference for identifying choroidal metastases.
- It highlights the diverse effects of treatment on tumor morphology and surrounding tissues.
- Further research can refine diagnostic criteria and treatment strategies for ocular metastases.
