Brief summary: Retinopathy of prematurity (ROP) is a disorder of development of the neural retina and its vasculature that can impact vision in vulnerable preterm neonates for a lifetime. This study tests high-speed optical coherence tomography (OCT) technology compared to conventional color photographs at the bedside of very preterm infants in the intensive care nursery, to characterize previously unseen abnormalities that can predict a need for referral for ROP treatment, or poor visual or neurological development later in life, up to pre-school age. Our long-term goal is to help improve preterm infant health and vision via objective bedside imaging and analysis that characterizes early critical indicators of ROP, and poor visual function and neurological development, which will rapidly translate to better early intervention and improved future care.

Detailed description: As an increasing percentage of preterm infants survive worldwide, the number of infants at risk for retinopathy of prematurity (ROP) is increasing. These infants are also at high risk for future abnormal visual function and neurodevelopment. While current screening approaches address identifying eyes for treatment of severe ROP, there are no attempts to address the later subnormal vision of many preterm infants. In part, this is due to a lack of information about the retina beyond that of retinal vascular development. In addition, the most common method to screen for ROP remains indirect ophthalmoscopic examination by physicians with annotated drawings for documentation, a method proven to be poorly reproducible and stressful to the fragile infant. Bedside retinal photographs enable documentation and the possibility for telemedicine approaches, but lack information about retinal microanatomy, are poor quality in darkly pigmented eyes and also are stressful to the infant because of the required light exposure. We need an infant-friendly, more practical approach to evaluate ROP efficiently and additional information about ocular and neurovascular development that could lead to improved clinical care.

This research builds on our group's ability to reliably capture and process non-contact, infrared optical coherence tomography (OCT) and OCT-angiography of retinal microanatomy and microvasculature at high speed, across a wide field of view, and at the bedside in preterm infants. Our overall objectives are threefold: first, to evaluate infant microanatomy and microvascular flow findings relevant to vision and neurodevelopmental outcomes in children; second, to translate and test our imaging achievements for real-world use by nurses at the bedside and for better clinical insight and feedback; and third, to gather additional data in eyes that progress to treatment and dive deeper into the insight that they provide into pathways of disease in ROP. The investigational OCT imaging will be used in this research to gather information that is otherwise not accessible to the physician. This research will lay the groundwork for future use of infant OCT markers to guide care.
