Summary

Grid pattern photocoagulation effectively reduces foveal thickness in diabetic macular edema long-term. This treatment improves visual acuity, especially in patients with good initial vision, offering a valuable therapeutic option.

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Area of Science:

  • Ophthalmology
  • Retinal diseases
  • Diabetic retinopathy

Context:

  • Diabetic macular edema (DME) is a leading cause of vision loss in diabetic patients.
  • Diffuse DME poses challenges for effective treatment and long-term management.
  • Grid pattern photocoagulation is a therapeutic modality for DME.

Purpose:

  • To evaluate the long-term efficacy of grid pattern photocoagulation in treating diffuse diabetic macular edema.
  • To assess changes in foveal thickness and visual outcomes following the procedure.
  • To determine the durability of treatment effects over an extended follow-up period.

Summary:

  • Grid pattern photocoagulation demonstrated sustained reduction in foveal thickness up to 30 months postoperatively.
  • Over 66% of eyes experienced a foveal thickness reduction exceeding 20%.

  • Visual acuity improved by 0.2 logMAR or more in 41% of eyes, with 80% achieving 0.5 or better if preoperatively 0.4 or better.

    • Impact:

    • Grid pattern photocoagulation is an effective long-term treatment for diffuse diabetic macular edema.
    • The procedure shows potential for significant visual acuity improvement in selected patients.
    • Foveal thickness measurement serves as a reliable quantitative outcome measure for photocoagulation efficacy in DME.
