Scientific Questions Being Studied

We are planning to explore disparities in healthcare access and utilization for patients with eye conditions across different demographic groups. We would like to evaluate risk of developing advanced/severe disease in different eye conditions, and understand how social determinants contribute to this risk while adjusting for other known risk factors. We are also interested in understanding the availability of social determinants of health data in this data repository compared to EHR clinical data warehouses alone.

Project Purpose(s)

  • Population Health

Scientific Approaches

We will build cohorts of patients with various eye diseases (i.e. diabetic retinopathy, retinal vein occlusions, glaucoma, etc.). Then we will develop concept sets and extract data on outcomes (i.e. development of complications), as well as predictors including clinical data and social data. We will draw on survey data and EHR data within All of Us. When genomic data and wearable data become available, we are interested in evaluating those data sources as well. We will use statistical modeling and machine learning to generate predictive models.

Anticipated Findings

We anticipate that there may be differential risk for developing complications based on disparities in healthcare access and utilization for patients with eye conditions.

Metformin and Glaucoma

There remain limited treatment options for glaucoma outside lowering intraocular pressure, which is not effective in all patients. Metformin, an antihyperglycemic drug used for the management of diabetes, is being increasingly explored for its neuroprotective effects in the eye. We…

Scientific Questions Being Studied

There remain limited treatment options for glaucoma outside lowering intraocular pressure, which is not effective in all patients. Metformin, an antihyperglycemic drug used for the management of diabetes, is being increasingly explored for its neuroprotective effects in the eye. We would like to investigate the relationship between metformin use and primary open-angle glaucoma incidence and progression using All of Us Data, given the limited studies focusing on this topic.

Project Purpose(s)

  • Drug Development

Scientific Approaches

We will build a cohort of patients with diabetes aged 40 and older, with no prior glaucoma diagnosis at baseline to assess glaucoma incidence. We will build a cohort of patients with diabetes aged 40 and older with an existing diagnosis of glaucoma to assess glaucoma progression. Then we will develop concept sets and extract data on outcomes (i.e. diagnosis of glaucoma, glaucoma progression represented by need for glaucoma surgery), as well as predictors including clinical data and social data. Analyses will be performed in R notebooks within the All of Us Workbench environment.

Anticipated Findings

We anticipate that metformin use will be associated with a reduced risk of developing primary open-angle glaucoma and reduced risk of progression to glaucoma surgery.
