Case 1: A posterior segment B-scan ultrasonography in a patient with typical iris coloboma and total cataract, showed well-defined excavated area in the inferior part just below the optic disc (red arrow) with the absence of retinochoroidal layer, suggestive of fundal coloboma (yellow arrow) (figure 1A). Involvement of macula and types of fundal coloboma can be ascertained quite fairly based on ultrasonography which might provide a clue or prediction about postoperative visual gain or visual prognosis.1 Figure 1 (A) Axial scan depicting a well-defined posterior ocular coat excavation below the optic nerve head (red arrow) is suggestive of fundal coloboma (yellow arrow). (B) Axial scan showing a well-defined excavated area over the optic nerve head (red arrow) suggests an optic disc coloboma (yellow arrow) along with thinned out inferior neuroretinal rim (purple arrow). (C) Axial scan revealed an uniform diffuse posterior bowing of the entire ocular coat temporal to …
