Retinal Imaging
Analysis workflows for OCT, fundus autofluorescence, and multimodal retinal data, with an emphasis on repeatable measurements and clinically meaningful summaries.
About me
Research optometrist exploring retinal imaging, visual function, and the measures we use to judge whether treatments are helping.
Aman Josan is a research optometrist at Oxford Eye Hospital. His work focuses on retinal imaging, visual function assessment, and statistical approaches for understanding disease progression and treatment response in inherited retinal disease and related ophthalmic conditions.
He is particularly interested in making clinical trial outcome measures more sensitive, interpretable, and reproducible. This includes work on microperimetry, low-luminance vision, image-derived biomarkers, network meta-analysis, and practical software for reviewing ophthalmic imaging data.

Research
Turning ophthalmic measurements into clearer evidence for patient-focused trials.
Visual Function
Work on microperimetry, low-luminance acuity, contrast sensitivity, and related tests used to capture functional change in inherited retinal disease.
Clinical Trial Endpoints
Statistical approaches for ranking, comparing, and interpreting endpoints so studies can detect change earlier and communicate treatment effects more clearly.
Open Analysis Tools
Practical software and reproducible scripts that make image review, annotation, and exploratory analysis easier for ophthalmology research teams.
Methods
Research methods and tools I use regularly.
R and reproducible analysis
Statistical modelling, longitudinal data, endpoint comparison, and treatment-effect analysis.
Clinical trial endpoints
Visual function endpoints, microperimetry, low-luminance measures, and trial outcome selection.
Ophthalmic imaging data
Retinal image review, annotation workflows, data extraction, and image-derived biomarkers.
Experience
Clinical and research roles.
