EMN abnormalities are associated with which retinal change?

Explanation:
EMN abnormalities reflect dysfunction in the pigment-producing retinal cells, so they manifest as disruption of retinal pigmentation. The retina’s pigment pattern depends on healthy retinal pigment epithelium and melanin distribution; when EMN is abnormal, these pigment patterns become irregular, producing patchy or mottled pigmentation. This is more consistent with pigment disruption than with tapetal hyperpigmentation (alteration of the tapetum’s reflectivity), neovascularization (new vessel growth from ischemia or inflammation), or retinal detachment (mechanical disassociation of retina).
