En face OCT imaging. a ILM en face image showing hyper signal on pigmented lesion (white arrows). b IPL en face level showing deeper bright signal temporally. c, d RPE and choriocapillary en face level respectively, demonstrating the dark artefact secondary to optical transmission blocking by the hamartoma. e Horizontal OCT B-scan section showing the hiperreflective tissue on the superficial layers. A very small portion of the outer retina reflectivity may be seen between the two islands of the hamartomatous tissue (yellow arrow). f Vertical OCT B-scan section revealing hyperreflective pigmented portion and full thickness shadowing
