Digital wide angle fundoscopy has been growing in recent years, and has showed to be useful for telemedicine. However, available commercial equipment and software are expensive. Our purpose is to report the development of a 3D printed device for smartphone contact wide angle fundoscopy and its utility in ROP screening and other pediatric retinal diseases.
The prototype consists in a magnetized surface base for the attachment of any type of smartphone that holds its camera aligned with a tubular conic handpiece (Fig 1). Fundus illumination is provided by means of an inner led light system with adjustable intensity.The handpiece also contains a lens system and different types of filters (Fig 2). In the conic distal end of the handpiece an universal adaptor for interchangeable attachment of different types of wide angle and magnifying contact lenses.Smartphone 4K video recording mode can be performed, avoiding the use of the smartphone zoom , due to the optical system inside the handpiece tube. This enhances the quality of edition of video images.
Premature infants and pediatric ocular fundus are easily and comfortably observed through this prototype. Detailed optic disk and macula observation with magnification is performed with the use of smartphone zoom . Wide field fundus visualization is possible with the attachment of a pediatric quadraspheric lens. Different types of filters provided with the prototype allows the better visualization of certain ocular structures, such as blood vessels, optic disk drusen, etc.
High quality instant pictures and video recordings may be obtained through this system that are particularly useful for telemedicine and teaching.
This is an abstract that was submitted for the 2017 ARVO Annual Meeting, held in Baltimore, MD, May 7-11, 2017.
