applanatum

Applanatum refers to a flattening or spreading out of a structure. In medicine, it is most commonly used to describe an applanatum iris, which is a condition where the iris, the colored part of the eye, appears flattened. This flattening can be a congenital abnormality or acquired due to various factors such as trauma, inflammation, or certain surgical procedures. A flattened iris can sometimes affect the drainage angle of the eye, potentially leading to increased intraocular pressure. Diagnosis typically involves a thorough ophthalmological examination, including slit-lamp microscopy. Treatment depends on the underlying cause and may involve medication to manage intraocular pressure or surgical intervention.

The term applanatum can also appear in other contexts, though less frequently. For example, in botany, it might describe a flattened or prostrate growth habit of a plant. However, its medical application, particularly concerning the eye, is the most recognized usage.
