Digital photography has changed the practice of ophthalmology, particularly in pediatric retina. In recent years, it has improved the ophthalmologic care of infants with a variety of pathologies. The RetCam (Clarity Medical Systems, Pleasanton, CA) fundus widefield imaging camera was first used in neonatal intensive care units (NICUs) in the 1990s. At that time it showed potential value in screening for retinopathy of prematurity (ROP), and studies proved its reliability in the diagnosis of plus disease in ROP. Several studies have demonstrated the RetCam's ability to aid the physician in screening, diagnosis and treatment.1-4 It has also become a tool for telemedicine in ROP as proven by the Stanford University Network for Diagnosis of Retinopathy of Prematurity (SUNDROP) program headed by Darius M. Moshfeghi, MD, at Stanford University in Palo Alto, CA, and the future of computerized reading as being developed by Michael F. Chiang, MD, at Columbia University in New York. We have also found the RetCam invaluable for resident training, parent education, and documentation of disease. It appears that digital imaging will become the standard of care in NICUs around the country and a key element in telemedicine.
IMAGING IN THE NICU
In the NICU, digital imaging has become essential.
Digital imaging helps the clinician as diagnostician, aids
documentation, and allows us to monitor in the postlaser
period, which is of utmost importance in the
aggressive Type 1 ROP that micro-preemies develop
(Figures 1 and 2). Using the RetCam Shuttle (Clarity
Medical Systems), we can continue this process of
monitoring the post-laser period in the clinic with fundus
photography (Figure 3). With an experienced photographer
and video capability, every child can be photographed
quickly and safely. The images bring the disease
process to life for the nurses, residents, and fellows,
and allow the parents to understand and participate
in their children's care. Once parents are able to
see the image, they understand the disease and
become the child's most important advocate when it
comes to vision.
IMAGING IN THE CLINIC
With the creation of the RetCam Shuttle camera, we
are able to utilize fundus photography in the clinic.
Fundus photography in the clinic permits parents to see
and understand the pertinent findings in their babies.
We can develop a common language and a better, more
objective way to communicate with our patients.
IMAGING IN THE OR
We use the RetCam Shuttle in the OR to document
the fundus image in every child who undergoes an
examination under anesthesia (Figures 4 and 5). We use
it for fundus photography through permanent keratoprosthesis
or as a Koeppe lens to document angle
pathology (Figures 6 and 7) and optic nerve changes.
The RetCam can document corneal findings as well
(Figures 8-10). It is important that all children who
undergo examination under anesthesia should have
documentation with digital images; the RetCam facilitates
this for almost all ocular findings.
The intravenous fluorescein angiography (IVFA) feature of the camera is particularly useful in the diagnosis of peripheral pathology (Figures 11 and 12). It is capable of documenting peripheral changes that we cannot capture on the upright camera in clinic. It is also an excellent tool for documenting changes in macular pathology in patients with permanent keratoprosthesis when optical coherence tomography and IVFA are not feasible in clinic.
SUMMARY
In summary, it is my opinion that digital imaging
should become the standard of care in NICUs where
diagnosis and treatment of ROP occurs and should be
available to document and follow disease states. The
Retcam and the RetCam Shuttle provide us with
unique opportunities to diagnose, train our next generation
of professionals, and educate the families of our
patients.
