Objective: To highlight the importance of conventional ultrasound in detecting very tiny lesions. In this case
detecting any extra-scleral extension involves optic nerve.
Methods: A young patient with 20/15 visual acuity underwent conventional ultrasound to rule out presence of
malignant melanoma. Upon thorough examination, classic findings of malignant melanoma were found. A dome
shaped, low to medium reflective, very vascular on both A-scan and Color Doppler choroidal lesion with minimal
sound attenuation. A very small extra-scleral extension and partial involvement of retro-bulbar optic nerve invasion
was clearly demonstrated during the exam. This was confirmed by magnetic resonance imaging (MRI) examination.
Results: Ophthalmic ultrasound is of a great value to detect and diagnose any intra ocular lesion. It was of a greater
value in detecting tiny extra-scleral extension and partial invasion of optic nerve.
Conclusion: Conventional ultrasound is of a great value and it should be the first step that can be taken to rule out
any extrascleral extension of any intra ocular lesion. It showed very high sensitivity in detecting very tiny invasion to
the retro-bulbar optic nerve in this case.
