Distinct Profiles of Choriocapillaris Involvement in Extensive Macular Atrophy With Pseudodrusen-Like Appearance and Geographic Atrophy

CC impairment is more pronounced in EMAP than in GA, with EMAP exhibiting more extensive and diffuse CCFD, particularly at the atrophy margins. This pattern may reflect a more aggressive vascular compromise in EMAP. These findings underscore a distinct CC pathoanatomy between the two conditions, with implications for disease progression and therapeutic targeting.
