About this trial

This is an interventional treatment trial for Idiopathic Juxtafoveal Telangiectasia focused on measuring Mactel, Macular Telangiectasia Type 2

Eligibility Criteria

21 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • The participant must be offered sufficient opportunity to review the informed consent form, agree to the form's contents and sign the protocol's informed consent;
  • The participant must have bilateral MacTel;
  • Women of childbearing potential and all men must agree to use an effective form of birth control during the study;
  • Participant must be medically able to undergo ophthalmic surgery for ECT implant;
  • The participant's best-corrected visual acuity 64 letters or better (20/50 or better) in the study eye;

Exclusion Criteria:

  • Participant is < 21 years of age;
  • Participant is medically unable to comply with study procedures or follow- up visits;
  • Participant has evidence of ocular disease other than MacTel that may confound the outcome of the study (e.g., diabetic retinopathy with manifest macular edema, uveitis, etc.);
  • Participant has a chronic requirement (e.g., ≥ 4 weeks at a time) for ocular medications and/or has a diagnosed disease, that in the judgment of the examining physician, may be vision threatening or may affect the primary outcome (artificial tears are permitted);
  • Participant has evidence of subretinal neovascularization in either eye;
  • Participant has evidence of central serous chorio-retinopathy (CSR) in either eye;
  • Participant has evidence of pathologic myopia in either eye;
  • Participant has had a vitrectomy, penetrating keratoplasty, trabeculectomy or trabeculoplasty;
