Ocular Melanocytosis

The two slit lamp photographs shown are the same slit lamp view but with different illumination to emphasize two findings in this 14 year old asymptomatic boy with ocular melanocytosis. A - With dimmer illumination, the scleral pigmentation is seen (yellow arrows). B - With brighter illumination, the sectoral iris hyperpigmentation can be seen. The orange arrows denote the intersection of the darker and lighter colored iris. When there is no hyperpigmented periocular skin, this condition is termed ocular melanocytosis. When the periocular skin is involved, it is termed oculodermal melanocytosis.
