Impact of diabetic retinopathy on vision-specific function

Area of Science:

• Ophthalmology
• Public Health
• Diabetology

Background:

• Diabetic retinopathy (DR) is a major complication of diabetes, potentially leading to vision impairment.
• Understanding the impact of different DR stages on vision-specific functioning is crucial for patient care and public health strategies.

Purpose of the Study:

• To assess how various stages of diabetic retinopathy (DR) affect vision-specific functioning in an Asian population.
• To identify specific DR classifications associated with reduced vision-specific quality of life.

Main Methods:

• A population-based cross-sectional study involving 3280 Malay adults aged 40-80 years in Singapore.
• Vision-specific functioning was measured using a validated scale, and its association with DR presence, macular edema (ME), clinically significant macular edema (CSME), vision-threatening DR (VTDR), and proliferative diabetic retinopathy (PDR) was analyzed.
• Regression models adjusted for demographic, diabetic, and socioeconomic factors.

Main Results:

• Among 357 diabetic participants, 23.2% had any DR, with 6.2% having PDR.
• Poorer vision-specific function was independently associated with any DR, ME, CSME, VTDR, and PDR.
• After adjusting for visual acuity, VTDR and PDR remained significantly linked to reduced vision-specific functioning, with individuals experiencing 6-12 times greater difficulty in daily activities.

Conclusions:

• Vision-threatening DR and proliferative DR significantly impact daily activities and vision-specific functioning.
• These findings underscore the critical need for early preventative measures to halt DR progression and preserve visual function.
