What are the different types of hemianopia and their visual field representations?
Understand the Problem
The content in the image discusses various types of visual field deficits, particularly conditions related to hemianopia and their anatomical correlations in the visual pathways.
Answer
Types of hemianopia and their visual field representations include monocular blindness, bitemporal hemianopia, binasal hemianopia, right homonymous hemianopia, right superior quadrantic hemianopia, right inferior quadrantic hemianopia, right homonymous hemianopia with macular sparing.
Here are the types of hemianopia and their visual field representations:

More Information
Hemianopia can be caused by various types of brain lesions which affect different parts of the visual pathways. Identifying the type of hemianopia can help in localizing the lesion.
Tips
A common mistake when identifying hemianopia types is confusing homonymous hemianopia with heteronymous patterns (binasal or bitemporal). Knowing the anatomical pathways helps avoid this confusion.
