What is Retinopathy of Prematurity (ROP)?
Retinopathy of Prematurity (ROP) is a potentially blinding eye disease that affects premature infants. It occurs when abnormal blood vessels grow in the retina, the light-sensitive tissue at the back of the eye. These vessels can be fragile and may leak or form scar tissue, which can cause retinal detachment and lead to permanent vision loss or blindness if not treated early.
Who Is at Risk?
ROP primarily affects:
- Babies born before 31 weeks of gestation
- Babies weighing less than 1500 grams (3.3 lbs) at birth
- Infants exposed to high levels of oxygen, especially in NICUs
Why Is ROP a Concern?
- No visible early symptoms — ROP can only be detected through specialized eye exams
- Rapid progression — Without timely intervention, it can quickly advance to severe stages
- Leading cause of preventable childhood blindness worldwide
How Is ROP Detected?
ROP is diagnosed through:
- Retinal exams performed by a pediatric ophthalmologist
- Specialized retinal imaging using devices like the 3nethra Neo (Neonatal Retinal Camera)
- Early screening is critical — typically begins a few weeks after birth for high-risk infants
Can ROP Be Treated?
Yes, early detection enables effective treatment, including:
- Laser therapy — Destroys abnormal blood vessels to prevent further damag
- Anti-VEGF injections — Inhibit growth of abnormal blood vessels
- Surgery — Required in severe cases with retinal detachment
What is a Retinopathy of Prematurity (ROP) Imaging Camera?
An ROP imaging camera is a specialized device designed to capture high-resolution images of the retina in premature infants. These cameras are essential for detecting and monitoring ROP, especially in infants who cannot communicate symptoms.
Why Is It Important?
ROP imaging cameras enable:
- Early detection of abnormal blood vessel development
- Accurate documentation for monitoring disease progression
- Remote diagnosis via telemedicine in underserved or rural areas
- Treatment planning by retinal specialists using objective image data
Key Features of an ROP Imaging Camera
- High-resolution retinal imaging
- Wide field of view (typically 120° or more) for comprehensive assessment
- Infant-safe design ensuring comfort and safety
- Mydriatic or non-mydriatic options (with or without pupil dilation)
- Portable and lightweight — ideal for NICUs and mobile units
- DICOM and PACS compatibility for seamless digital storage and sharing
- Telemedicine support for remote consultations and expert reviews
Where Are ROP Cameras Used?
- Neonatal Intensive Care Units (NICUs)
- Pediatric ophthalmology clinics
- Mobile outreach units in rural or underserved areas
- ROP screening programs in hospitals and specialized centers
