The initial sign of Bull's eye maculopathy while taking Chloroquine is RPE _____________ within the macula.

Explanation:
Early chloroquine-induced maculopathy shows mottling of the retinal pigment epithelium in the macula. This patchy, irregular pigmentation reflects initial RPE dysfunction from the drug’s accumulation. As toxicity progresses, the RPE and overlying photoreceptors thin and deteriorate, leading to more pronounced changes such as atrophy and the bull’s-eye appearance. Edema isn’t a typical early sign, and true atrophy occurs later after ongoing damage. Hyperpigmentation can occur but is not the earliest, most characteristic change.
