Abstract

Objective

This study aimed to understand the impact of sickle cell disease (SCD) or sickle cell trait (SCT) on diabetic retinopathy and retinopathy treatment burden.

Design

Cross-sectional study.

Subjects and Controls

Utilizing the American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight), 3742 patients with comorbid diabetes mellitus (DM) and either SCD or SCT were included in the analytic sample. A race-stratified group of 3742 patients with DM and no known SCD was included as controls.

Methods

Data analysis was performed using R (R Project 4.2.0). Descriptive statistics summarized demographic data among patients with comorbid SCD or SCT and among controls. Chi-square tests compared clinical outcomes (proliferative diabetic retinopathy [PDR], diabetic macular edema [DME]) and ocular procedure frequency across patients with DM and SCD or SCT and across controls. Multivariate logistic regression models examined the likelihood of clinical outcomes and ocular procedures across patients with and without comorbid SCD or SCT while adjusting for insurance, smoking status, and demographic factors.

Main Outcome Measures

Frequency of clinical outcomes and ocular procedures.

Results

All measured clinical outcomes were more frequently documented among patients with DM and either SCD or SCT as compared with those with DM alone. Of the 7 ocular procedures studied, 5 were more common among the DM with SCT or SCD group as compared with controls (P < 0.001). On regression analysis, DM patients with comorbid SCD or SCT had 7.36 and 4.22 times greater odds of PDR and DME, respectively (confidence interval for PDR: 6.36–8.54, confidence interval for DME: 3.68–4.85).

Conclusions

This analysis suggests that DM patients with comorbid SCD or SCT have an increased likelihood of DM-related microvascular pathology and a higher ocular treatment burden. Prospective studies are needed to further characterize the relationship between DM and SCT or SCD.
