Mydriatic visual acuity in diabetic patients: a randomized controlled trial

Area of Science:

• Ophthalmology
• Diabetology

Background:

• Diabetic patients require regular eye examinations to monitor for complications.
• The timing of pupil dilation during eye exams can impact patient experience and clinic efficiency.

Purpose of the Study:

• To determine if dilating pupils before or after refraction and visual acuity assessment affects patient advice.
• To compare patient outcomes and satisfaction based on pupil dilation timing in diabetic individuals.

Main Methods:

• A randomized controlled equivalence trial involving 316 adult diabetic patients.
• Patients were randomized to receive tropicamide 0.5% pupil dilation either before or after eye assessments.
• Outcomes included advised follow-up time, refractive correction advice, further diagnostics, treatment recommendations, exam duration, and patient satisfaction.

Main Results:

• No significant differences were observed in advised follow-up intervals, refractive correction advice, further diagnostics, or therapy recommendations between groups.
• The group receiving pupil dilation before assessments experienced significantly shorter waiting times (22.25 vs. 36.18 minutes).
• Patient satisfaction regarding optometrist attention and refractive advice was similar or higher in the group dilated before assessments.

Conclusions:

• Pre-refraction pupil dilation in diabetic patients does not alter clinical advice compared to post-refraction dilation.
• Dilation before eye exams enhances clinic efficiency by reducing waiting times.
• This strategy maintains or improves patient satisfaction, offering benefits to both patients and clinicians.
