Lateral Geniculate Nucleus (LGN) degeneration refers to the deterioration or damage of the lateral geniculate nucleus, a structure located in the thalamus region of the brain. This condition can lead to various symptoms affecting vision and overall health. Here, we’ll delve into the types, causes, symptoms, diagnostic methods, treatments, medications, surgeries, preventions, and when to seek medical attention for LGN degeneration.
Types of LGN Degeneration:
There are various types of LGN degeneration, including:
- Primary LGN Degeneration: This occurs due to direct damage or injury to the lateral geniculate nucleus.
- Secondary LGN Degeneration: Indirect damage to the LGN caused by other conditions such as optic nerve damage or brain trauma.
Causes of LGN Degeneration:
