Ophthalmic Specimen Examples
|1. Gelatinous drop-like corneal dystrophy is characterized by ropy thick amyloid deposits underneath Bowman’s layer and in anterior stroma without accompanying epithelial erosion. It is an autosomal recessive dystrophy with adult age onset. It is caused by genetic defects in keratoepithelin gene (also known as transforming growth factor, beta-induced gene or TGFBI) on chromosome 5.|
|2. Melanocytoma of optic nerve head is composed of polyhedral cells with low nuclear cytoplasmic ratio, smoothly contoured nuclei devoid of mitotic activity, and usually heavily pigmented cytoplasm. The neoplasm is ill demarcated showing feathering edges mimicking invasion (seen here spilling into neighboring optic nerve). It does not have metastatic potential and can be treated by surgery.|
|3. Normal iris and lens: the image shows pupillary zone of iris displaying anterior border layer, minimally pigmented iris stroma, anterior pigment epithelium with smooth muscle fibers of dilator muscle, and completely pigmented posterior pigment epithelium. Pupillary border of iris shows the sphincter muscle in stroma responsible for pupillary constriction. The lower aspect of image reveals anterior face of normal lens with externally placed lens capsule and internal lens epithelium.|
|4. Incarcerated iris in perforated corneal wound in this image shows crater like corneal perforation borders with central incarcerated iris obstructing the wound and burgeoning to the external ocular surface. Complete disorganization of anterior chamber elements is readily identifiable.|
