简要总结

The primary objective of this multi-center clinical study is to evaluate the validity, reliability, feasibility, safety and relative cost-effectiveness of a retinopathy of prematurity (ROP) telemedicine evaluation system to detect eyes of at-risk babies who meet referral warranted ROP (RW-ROP) criteria and therefore need a diagnostic evaluation by an ophthalmologist experienced in ROP.

We shall:

  1. Calculate the accuracy, using sensitivity and specificity, of the system to provide remote evaluations when compared with the findings of a "gold standard" indirect ophthalmoscopic examination performed by a Study-certified ophthalmologist, rigorously trained in ROP diagnostic examinations (validity);
  2. Determine intra-reader and inter-reader agreement for deciding whether digital images indicate that the eyes of a baby are in need of diagnostic indirect ophthalmoscopy by an ophthalmologist experienced in ROP (reliability);
  3. Determine whether imaging evaluation can be achieved for each baby (feasibility);
  4. Examine ocular and systemic complications associated with digital imaging and compared with those associated with diagnostic examinations performed by an ophthalmologist (safety);
  5. Compare the costs and benefits of adopting a telemedicine retinal imaging system compared to the current cost of indirect ophthalmoscopic examinations (cost-effectiveness).

详细描述

Eligibility Criteria:

• Babies with birth weights of <1251 grams(g) at selected large clinical centers in the US and Canada.

Procedures:

• Participants will undergo both digital retinal imaging and clinically indicated indirect ophthalmoscopic examinations on the same day. Wide-field digital images (WF-DI) of both eyes will be captured by non-physician Certified ROP Imagers (CRIs) using standardized imaging protocols. The RetCam Shuttle® (Clarity Medical Systems, Pleasanton, CA), a corneal-contact camera that captures wide field (130 degree field of view) retinal images, will be used.

入选标准

  • Babies with birth weighs of <1251g at selected large clinical centers in the US and Canada.
  • Admitted to a participating Neonatal Intensive Care Units (NICU) and expected to survive to 28 days.
  • Likely to remain in participating NICU for serial ROP exams.
