    Collapse Overview
    Dr. Jonnal studies retinal neurons and develops methods to observe the anatomy and physiology of these cells in the living human eye. The tools developed in his lab have the potential to dramatically improve diagnosis of retinal disease and accelerate the development of therapeutic interventions.

    Altmetrics Details PMC Citations indicate the number of times the publication was cited by articles in PubMed Central, and the Altmetric score represents citations in news articles and social media. (Note that publications are often cited in additional ways that are not shown here.) Fields are based on how the National Library of Medicine (NLM) classifies the publication's journal and might not represent the specific topic of the publication. Translation tags are based on the publication type and the MeSH terms NLM assigns to the publication. Some publications (especially newer ones and publications not in PubMed) might not yet be assigned Field or Translation tags.) Click a Field or Translation tag to filter the publications.
