Description of Research Expertise
Dr. Aleman has extensive expertise in the study of hereditary retinal degenerations. He is part of the Retinal Degeneration Center at Scheie Eye Institute. His research expertise includes state-of-the-art psychophysical, electrophysiological and imaging studies in patients and animal models of the human disease. Most of the studies in which Dr. Aleman is an investigator are aimed to lead patients with these incurable retinal degenerations into clinical trials. The macular pigment is a carotenoid complex proposed to have a protective role in the human central retina. With the long-term goal of finding ways to prevent central vision loss in retinal degenerative diseases, Dr. Aleman has studied macular pigment levels in patients with inherited retinal disorders.Clinical Trials
Dr. Aleman is an investigator in an upcoming gene therapy trial for Leber’s congenital amaurosis, the most severe form of inherited retinal degeneration.
Key Words
Hereditary Retinal Degenerations, retinitis pigmentosa, macular disorders, optical coherence tomography, electroretinogram
Description of Clinical Expertise
Dr. Aleman cares for patients with hereditary retinal degenerations at the Center for Hereditary Retinal Degenerations at Scheie Eye Institute. He is also responsible for all clinical electrophysiological investigations within this department, which provides this service to a large number of specialists in the region.Description of Other Expertise
