Clinical Trial Summary

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).


Description:

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.

Masking:

• Study-certified Ophthalmologist and Study-certified Imager at the clinical sites will be masked to each other's findings. The Study Clinical Coordinator (SCC) will remain unmasked. SCC will monitor the clinical noteworthy events and report all adverse events to the site Institutional Review Board (IRB), the Project Director at the Office of Study Chair, and to the Data Coordinating Center (DCC). DCC will prepare closed-session Data Monitoring and Oversight Committee (DMOC) reports. The PI at each site will monitor adverse events.

Outcome Measures:

• The primary outcome measure is detection of referral warranted ROP (RW-ROP) on digital images. Retinal images will be graded by Trained Readers using a standardized protocol to identify eyes with RW-ROP. Results of the gradings will be compared to the diagnostic examinations being performed on each child at the same session when images taken. For comparison, images will also be graded by ROP experts (Expert Readers).
