What does scotoma refer to in an eye exam?

An area of vision with increased acuity

An area of partial or complete loss of vision

Scotoma refers to an area in a person's visual field that is partially or completely devoid of vision, often described as a "blind spot." This condition can arise from various eye issues, including retinal damage, optic nerve disease, or neurological disorders affecting the visual system. During an eye exam, the detection of a scotoma is significant as it can help identify underlying problems that may require further investigation or treatment. The presence of a scotoma serves as an important indicator for healthcare professionals to assess the patient’s visual function and overall eye health.

The other options do not accurately define scotoma. Increased acuity is associated with enhanced visual sharpness, eye strain refers to discomfort from extensive visual tasks, and intraocular pressure measurements relate to glaucoma diagnosis, none of which align with the definition of scotoma.

A type of eye strain

A measurement of intraocular pressure
