Which of the following conditions is associated with a blue/yellow color defect according to Kollner's Rule?

A blue/yellow color defect is typically associated with abnormalities in the central visual pathways and is a significant aspect of color vision deficiencies. According to Kollner's Rule, this type of defect is primarily linked with retinal diseases, which affect the photoreceptors or the retinal layers, leading to a distortion in color perception.

Macular degeneration affects the central part of the retina known as the macula, which is responsible for sharp central vision. This condition disrupts the transmission of visual information, particularly for colors that are processed in the central visual pathways, thus leading to difficulties in perceiving blue and yellow colors distinctly. This aligns well with the characteristics of the blue/yellow defect.

The other conditions listed typically present with different types of color vision deficiencies. For instance, optic neuritis is more likely to cause a red/green color defect, while chronic glaucoma typically affects peripheral vision more than color perception. Cataracts can also cause changes in color perception but are generally associated with a dimming of vision rather than a specific color defect like blue/yellow.

In summary, the association of a blue/yellow color defect with macular degeneration is well established as it directly impacts the structures involved in color processing, thereby reinforcing the correctness of choosing macular degeneration in this
