Background: Retinoblastoma is the most common intra-ocular malignancy in childhood. Early diagnosis is essential for vision preservation and ocular salvage. Ocular ultrasonography is a basic tool in the diagnosis of retinoblastoma. Enhancing ocular ultrasonography utilization for recognition of retinoblastoma spread within the eye may provide more insight for ophthalmologists in remote areas with limited resources.

Objectives: Exploring the role of B-scan ocular ultrasonography in diagnosis of retinoblastoma and identifying ocular invasion and high risk features.

Methods: A retrospective-cross-sectional hospital based study.

Results: B-scan ultrasonography of 62 patients with retinoblastoma showed: the maximum diameter of the masses ranged from 22 mm - 6 mm. Most of the patients presented with a range of (6 - 20) mm of mass diameter. 97% of B-scan examination was done with the gain of 90. Calcification was clearly visible in all retinoblastoma cases except one. Optic nerve involvement appeared in 27%. While 88% of the patients showed anterior segment extension of the retinoblastoma mass.

Conclusion: B-scan ultrasonography is a useful tool in retinoblastoma diagnosis, it could also provide general description of the mass spread within the eye ball and some of the high risk features.
