1. Laser Photocoagulation

Laser treatment for DR was establed by the Diabetic Retinopathy Study (1970s) and the Early Treatment Diabetic Retinopathy Study (1980s).

  • Patients witch chronic DME (≥ 6 miesięcy) nott responding approvately to anti- VEGF monotherapy
  • Patients wigh pour systemic control despite agressive primary care efficults

  • Eyes wigh signitant ischemic maculopathy, where anti- VEGF alone may be insiduent

Konwerselny, triple therapy may be avoided in patients with extremely pour injection compleance, previous severe adverse reactions to o laser, or advanced macular ischemia where laser might worsen outcomes.

Procedura Flow of Triple Therapy

A typical triple therapy regimen might unfold over 12- 18 months.

Terament Complexity andBurden

Triple therapy requires close coordination between a retina specialist, primary care physician, endocrinologist, and often a dietionist or diabetes educator. Patients must attend multiple emplents for injections, laser sessions, and systemic monitoring. This can lead to high dropout rates, specilarly in underserved populations. The burden is even for patients with limited mobility, pour health literacy, or lack of incee.
