Study summary

In this clinical trial, we plan to evaluate the usefulness of artificial intelligence (AI) software paired with a handheld retinal camera to compare diabetic retinopathy status in Bolivian patients as read by retina specialists versus the AI software.

Study population

Patients who are known diabetics in the hospital, or seeking help from the eye clinics or from associated specialties, e.g. endocrinology, will be included in the study as subjects. The Investigators will also recruit subjects who are evaluated in organized outreach visits in the community.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Male or female subjects who are at least 18 years old who have full legal capacity to volunteer on the date the is signed;
  2. Subjects who can follow the instructions by the clinical staff at the clinical site, and can attend examinations on the scheduled examination dates;
  3. Subjects who have been diagnosed with Type I or Type II diabetes mellitus.

Exclusion criteria

Exclusion Criteria:

  1. Subjects unable to tolerate ophthalmic imaging;
  2. Subjects who have been scheduled for but have not yet undergone the following surgeries: Cataract Surgery (including any related follow-up procedures) or Vitrectomy.
  3. Subject blind in one eye due to any cause
  4. Subjects who have a condition or a situation, which in the investigator's opinion, may put the subject at increased risk, confound study data, or interfere significantly with the subject's study participation.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Interventions

  • OtherPicture of the retina with a handheld retinal camera

    Patient with diabetes will have their undilated and dilated images taken, with the images being centered on the macula and on the optic disc.

What researchers measure

Primary outcomes

  1. Number of subjects where the image readout by retina specialists match the readouts by EyeStar AI system for identifying diabetic eye disease

    To quantify image analysis performance of the EyeStar AI system paired with Pictor Plus cameras for the detection of referable Diabetic Retinopathy (DR), defined as severe non-proliferative diabetic retinopathy (NPDR), proliferative diabetic retinopathy (PDR), or diabetic macular edema (DME) against adjudicated reads of retinal images by retina specialists

    Time frame: 3 months

Secondary outcomes

  1. Number of subjects with gradable images taken by the hand held camera

    Pictures taken by the handheld retinal camera will be graded by the retina specialists for the quality of image for readouts

    Time frame: 3 months

  2. Number of subjects with ocular diseases other than diabetic retinopathy between the readout by the EyeStar AI system and those by the retina specialists

    To assess the performance of the system in detection of other ocular diseases such as macular degeneration and glaucoma

    Time frame: 3 months
