Iris Ring Melanoma Presenting as Scleral Pigmentation

Area of Science:

• Ophthalmology
• Oncology
• Medical Imaging

Background:

• Iris melanoma is a rare intraocular malignancy.
• Atypical presentations can lead to diagnostic delays.
• Ring melanoma is an exceptionally rare variant of uveal melanoma.

Observation:

• A 65-year-old patient presented with a pigmented scleral lesion.
• Ophthalmic and ultrasound examinations were performed.
• A diagnosis of ring melanoma was made.

Findings:

• Histopathology confirmed iris ring melanoma after enucleation.
• This variant presents a unique ring-shaped growth pattern.
• Unilateral pigmentary glaucoma can be an indicator.

Implications:

• Early diagnosis of ring melanoma is critical for effective management.
• Gonioscopy, transillumination, and ultrasound are key diagnostic tools.
• Increased awareness can prevent misdiagnosis and delayed treatment of this rare condition.
