Understanding Blue Light Retinal Damages And The Methods Of Prevention, Amelia Lee

Senior Honors Theses

Light emitting diode (LED) lights that comprise television screens, phone displays, laptops, and tablets have been studied by scientists in order to understand the implications of blue light radiation and the effects that it has on the human body—especially the retina of the eye. The retina is comprised of highly metabolic cells, and when those cells are placed under oxidative stress, death occurs causing ocular disease. Additionally, excess blue light exposure causes shifts in biological rhythms that govern patterns of alertness and sleep. Recently scientists began studying the methods of blue light prevention. Some studies show that blue light radiation …

Corneal Disease And Air Pollution Levels In Detroit: Preliminary Results And Future Directions​, Sachin Ketkar, Matthew Silbergleit, Vaama Patel

Medical Student Research Symposium

Purpose: To determine if Detroit zip codes with elevated air pollution levels demonstrate increased incidence of corneal disease.

Background: 82 million people in the United States live in counties with air quality concentrations above the National Ambient Air Quality Standards. Air pollution’s detrimental effects on an individual’s health has been well documented. Much of this research has focused on the pulmonary system. The eye, another mucous membrane exposed to the external environment, has been largely ignored

Methods: After an initial literature review of similar studies, 14 corneal diseases and 5 pollutants were selected to be evaluated. Kresge Eye Institute’s patient …

Determining Risk Factors That Affect Progression In Patients With Nonproliferative Diabetic Retinopathy, Dalbert J Chen, Jacky C Kuo, Alex J Wright, Alice Z Chuang, Wenyaw Chan, Robert M Feldman, Eric L Crowell

Journal Articles

PURPOSE: to determine risk factors that affect nonproliferative diabetic retinopathy (NPDR) progression and establish a predictive model to estimate the probability of and time to progression in NPDR.

RESULTS: Two hundred thirty patients were included. Initially, 65 eyes (28.3%) had no retinopathy; 73 (31.7%) mild NPDR; 60 (26.1%) moderate NPDR; and 32 (13.9%) severe NPDR. Patients were followed for a mean of 5.8 years (±2.0 years; range 2.1-9.4 years). 164 (71.3%) eyes progressed during the follow-up. Time-independent risk factors affecting progression rate were age (hazard ratio (HR) = 0.99,

CONCLUSION: HbA1c level is a significant modifiable risk factor in controlling …
