Anatomy Optics › Optic nerve anatomy
Optic disc melanocytoma
Melanocytoma is a deeply pigmented variant of melanocytic nevus that classically occurs in the optic disk, sometimes with contiguous involvement of the adjacent retina or choroid. Histopathologically, melanocytoma is composed of intensely pigmented round to oval nevus cells with benign features.
Anatomy Optics › Iris and ciliary body anatomy
Bridging Iris coloboma
A bridging iris coloboma is a rare congenital eye condition where a thin strand or thread of iris tissue stretches across the gap of a typical coloboma. This strand divides the pupil area or bridges the split, making the pupil look partially segmented rather than completely open into a keyhole shape.

Retina Vitreous › Retinal detachment
Retinal detachment B scan
B-scan ultrasonography is essential when media opacity (e.g., vitreous hemorrhage, dense cataract) precludes fundus visualization. It enables assessment of the retina in the presence of vitreous hemorrhage or other media opacity, and is used to diagnose diabetic retinal detachments and define the extent and severity of vitreoretinal traction in these settings.The detached retina appears as a bright, mobile, & echogenic membrane tethered to the optic disc but separated from the choroid, and this appearance on ultrasonography is both highly sensitive and specific for retinal detachment. The membrane’s mobility and folding are best appreciated during kinetic examination, where the patient moves the eye and the detached retina undulates, remaining anchored at the optic nerve head.
