Summary
Optic disk melanocytoma, a benign tumor, can lead to severe complications like vision loss. This case highlights vitreous seeding from tumor necrosis causing inflammation and secondary glaucoma.
Area of Science:
- Ophthalmology
- Oncology
Background:
- Melanocytomas of the optic disk are typically benign and stationary tumors.
- Complications, though rare, can arise from these lesions, potentially leading to significant visual impairment.
Observation:
- A case report details a 33-year-old female with a large, unilateral optic disk melanocytoma.
- Over nineteen years, the tumor exhibited massive intraocular seeding, leading to cataract, secondary glaucoma, and amaurosis.
Findings:
- Pathological examination confirmed the optic disk melanocytoma diagnosis.
- Vitreous seeding resulted from tumor necrosis and melanin dissemination, triggering inflammatory responses and secondary glaucoma.
Implications:
- This case underscores that optic disk melanocytomas, despite their benign nature, can cause severe ocular complications.
- Understanding the mechanism of vitreous seeding is crucial for managing potential visual loss in these patients.
