Who may be able to join
AI generated eligibility summary. Written by an AI model from the official source data and checked on a sample basis. It can contain mistakes, so confirm anything important against the original source. How we use AI
Who might be able to join this trial:
- Adults aged 18 years or older
- People who have been diagnosed with type 1 or type 2 diabetes
- People who are currently using insulin or oral diabetes medications on a regular basis to manage their diabetes
- People who live within a 2-hour drive of the hospital or clinic where the trial is being conducted
- People who have at least one eye that meets the specific eye-related criteria for the trial (see eye criteria below)
- People who are able and willing to use a home vision-testing device and a home eye-scanning device on their own or with family help, after receiving training
- People who are able and willing to give their informed consent to take part
Eye-specific criteria — the eye being studied must also meet these requirements:
- The eye has a specific type of swelling in the centre of the retina caused by diabetes (called diabetic macular oedema, or DME), confirmed by a retinal scan showing swelling above a certain thickness threshold
- The eye has a best-corrected vision level that falls within a specific range — not better than 20/32 and not worse than 20/320 — measured within seven days of joining the trial
- The eye has either never been treated for DME before, or has had a limited number of anti-VEGF injections (a type of eye injection) within specific time limits (confirm with trial site for the exact injection history requirements)
- The eye is clear enough, and the person is cooperative enough, to allow for good-quality retinal photographs and scans to be taken
Who may not be able to join:
- People whose general health is considered unstable by the investigators, including those with poorly controlled blood pressure, heart disease, kidney disease, or blood sugar levels
- People who have received a type of medication called anti-VEGF or pro-VEGF treatment (given into the body, not the eye) in the 4 months before joining, or who would need to use these medications during the trial
- People who have taken part in another clinical trial involving an unapproved drug within 30 days of joining
- People with a blood pressure reading above 180/110 — however, if blood pressure is brought below this level with medication, the person may still be considered (confirm with trial site)
- People who have had a heart attack, stroke, mini-stroke (TIA), a serious heart event requiring hospitalisation, or treatment for severe heart failure in the 4 months before joining
- Women who are pregnant, breastfeeding, or planning to become pregnant within the next 2 years
- People who are currently taking part in another clinical trial
- People who expect to move to a location more than a 2-hour drive from the trial site within the first 12 months of the study
Eye-specific exclusions — the eye being studied cannot have:
- Retinal swelling caused by something other than diabetes
- Any laser treatment, surgery, or steroid injections for DME in the eye in the past 12 months
- Anti-VEGF eye injections given for a condition other than DME (such as certain other eye diseases) in the past 6 months, or an anticipated need for such injections in the next 6 months
- Other eye conditions that could affect vision during the trial, such as blocked blood vessels in the eye, eye inflammation, or a certain type of glaucoma
- A cataract that, in the investigator's opinion, is significantly reducing vision (by 3 lines or more on an eye chart)
- Major eye surgery (including cataract removal, vitrectomy, or other procedures inside the eye) in the past 4 months, or surgery expected within 6 months of joining
- Uncontrolled glaucoma
- A significant active eye infection or inflammation, such as severe conjunctivitis or eyelid inflammation
