简要总结

Prospective interventional study on 60 eyes of resistant diabetic macular edema and central retinal vein occlusion that will receive suprachoroidal injection of Triamcinolone Acetonide (SCTA).

详细描述

  • Prospective non randomized interventional study on 60 eyes of 40 patients with previously diagnosed macular edema secondary to type 1 or 2 diabetes mellitus and 60 eyes with central retinal vein occlusion will be included.
  • The study will be conducted from January 2021 to June 2021.
  • For transition to suprachoroidal injection of Triamcinolone Acetone (TAAC) a diagnosis of resistant DME is required.
  • Inclusion criteria:

Patients fulfilling one or more of the following criteria will be considered to have resistant diabetic macular edema (DME) after at least 3 consecutive monthly anti vascular endothelial growth factor (VEGF) injections in the previous 6 months: central macular thickness greater than 300 μm by spectral-domain optical coherence tomography (SD-OCT), reduction of retinal thickness by less than 10% of baseline retinal thickness, or suboptimal visual improvement (failure to gain at least 3 lines on the Snellen chart).

  • The subjects included in the research will undergo the following tests and investigations:
  1. Visual acuity testing (uncorrected and best corrected).
  2. Intra ocular pressure (IOP) by applanation tonometry.
  3. Anterior segment examination by slit lamp
  4. Posterior segment examination by indirect ophthalmoscope and 78 D lens
  5. Spectral domain Optical coherence tomography (OCT).
  6. Ocular fundus photography and fluorescein angiography.
  • Exclusion criteria will be:
  1. Previous intraocular surgery (except cataract surgery done more than 6 months before the study).
  2. Coincident retinal pathology as choroidal neovascular membrane and age related macular degeneration.
  3. Previous laser photocoagulation.
  4. Intravitreal injection of triamcinolone acetonide.
  5. Prior ocular inflammation.
  6. The presence of retinal degeneration.
  7. Patients who didnot complete 6 months of follow up
