    Diabetic patients undergoing pan-retinal photocoagulation (PRP) often experience visual difficulties like adjusting to light and color sorting, even if their visual acuity remains good. Many patients, however, remain positive about the treatment

    Area of Science:

    • Ophthalmology
    • Diabetic Retinopathy Management

    Background:

    • Pan-retinal photocoagulation (PRP) is a standard treatment for diabetic retinopathy.
    • Visual disturbances can occur post-PRP, impacting daily life.

    Purpose of the Study:

    • To assess the frequency and severity of visual difficulties in diabetic patients after PRP.
    • To investigate the relationship between visual acuity and reported visual problems.

    Main Methods:

    • Survey of 35 diabetic patients who previously underwent PRP.
    • Correlation analysis to link visual acuity with specific functional difficulties.

    Main Results:

    • Frequent issues include adjusting to dim/bright light and sorting dark colors.
    • Difficulties in judging distances, navigating stairs, and obstacle avoidance increased post-PRP.

  • Some difficulties, like daytime driving, correlated with visual acuity, but many frequent complaints did not.

    • Conclusions:

    • PRP can lead to various visual complaints unrelated to visual acuity.
    • Despite visual challenges, patients generally hold positive views towards PRP treatment.
