How Do You Spell PARACENTRAL SCOTOMA?

1. Paracentral scotoma is a term used to describe a specific type of visual field defect that occurs in the central region of the visual field. A scotoma refers to an area of reduced or absent vision, while the term "paracentral" specifies that this defect occurs around the central area of focus in the field of vision.

   In individuals with paracentral scotoma, there is a localized loss of vision in the central or parafoveal region, which may manifest as a small blind spot or a distorted area that affects the ability to see clearly and accurately. This defect may affect one eye or both eyes, and is commonly associated with various eye conditions such as macular degeneration, glaucoma, or optic nerve damage.

   The specific characteristics of a paracentral scotoma may vary depending on the underlying cause. For example, in macular degeneration, a common age-related eye disorder, the scotoma is typically characterized by a dark or blurry spot in the central vision. In glaucoma, on the other hand, the scotoma may be in the form of an arc or crescent shape, affecting the peripheral portion of the central vision.

   Paracentral scotomas can significantly impact visual function, especially tasks that require sharp central vision such as reading, recognizing faces, and driving. However, with appropriate diagnosis and management, including the use of visual aids or interventions to manage the underlying condition, individuals with paracentral scotoma can often adapt and maintain functional vision.

2. One which is only partly central, the fixation point not being entirely obscured.
