What visual characteristic might be impaired in a person with Stargardt's disease?

In Stargardt's disease, a genetic condition primarily affecting the retina, the primary visual characteristic that might be impaired is color discrimination. This condition leads to the degeneration of the photoreceptor cells in the macula, which is responsible for central vision and the perception of fine details, including color.

The macula plays a crucial role in our ability to see colors accurately, as it contains a high concentration of cone cells, which are sensitive to color and light. When these cells are damaged or deteriorate due to Stargardt's disease, the ability to discern different colors can be significantly affected. As a result, individuals may experience difficulty distinguishing between similar colors or may have an altered perception of colors.

While depth perception, visual field, and contrast sensitivity can be impacted in various eye conditions, the hallmark of Stargardt's disease is more closely related to color discrimination deficits due to its specific effect on the macular area of the retina. This makes color discrimination the most relevant impairment in the context of this disease.
