Abstract

Methods: Prospective observational case series. Forty eyes of retinoblastoma with intraocular foci of calcifications were analyzed using RetcamIII during routine examinations under anaesthesia performed on patients (aged ≤5 years) attending ocular oncology clinic at a tertiary hospital and findings were recorded. The calcifications were confirmed using conventional B-scan ultrasound feature: highly echogenic foci on B-scan with a high amplitude spike. Results: At presentation, 100% of eyes demonstrated a light scattering effect (ret-glow) when the illumination level of RetcamIII was raised. A bright yellow-white color was observed in the images obtained from RetcamIII. The color immediately faded when the illumination was reduced back to low levels. Conclusion: Ret-glow (“glow of retinoblastoma”) is a useful clinical marker of retinoblastoma on RetcamIII and hallmarks the presence of calcification in the lesion.
