Patients with minimal or no retinopathy are unlikely to require retinal treatment for diabetic retinopathy within 2 years of screening, according to a study published in JAMA Ophthalmology.

The retrospective cohort study evaluated patients who were initially screened in 2012, had photographs indicating minimal or no retinopathy and then had at least 2 years of follow-up.

“The medical records for patients with minimal or no retinopathy were cross-referenced with Current Procedural Terminology codes used for intravitreal injections, retinal lasers and pars plana vitrectomy,” Bobeck S. Modjtahedi, MD, Kaiser Permanente Baldwin Park Medical Center, California, and colleagues wrote. “We identified patients then had their medical records manually reviewed; the clinical indication and type of interventions were subsequently categorized.”

A total of 116,134 patients had diabetic retinopathy screening photographs taken, 81,544 had no retinopathy, and 11,689 had minimal retinopathy. Of those, 85.4% of patients without retinopathy and 83.9% of patients with minimal retinopathy had 2 years of follow-up evaluations by clinicians.

According to the study, 11 patients without baseline retinopathy required treatment for complications of diabetic retinopathy, and 44 patients required intervention because of nonrelated conditions.

Results showed that the most common intervention for treatment of diabetic retinopathy was panretinal photocoagulation for proliferative diabetic retinopathy in patients with minimal and patients without baseline retinopathy. Pars plana vitrectomy was the most common intervention in the study not related to diabetic eye disease, as 42 patients without baseline retinopathy and three patients with minimal retinopathy underwent this procedure.

 

“Most interventions were rendered for conditions not directly related to diabetic retinopathy,” the authors wrote. “Additional study is required to determine the ideal screening intervals for patients with diabetes as well as the economic, clinical and practical value to ultra-widefield imaging.” by Erin T.
