To describe the ultrasonic characteristics in the evolution of zone 1 retinopathy of prematurity(ROP).
We used a handheld 20-MHz ultrasound system to examine six eyes of three neonates, previously noted by indirect ophthalmoscopy screening to evidence zone 1 ROP without retinal detachment.
In four of six eyes,(66%),there was ultrasonic evidence of peripheral retinal traction at the anterior junction of vascularized and non-vascularized retina that was not visualizable by indirect ophthalmoscopy. The later clinical course in these four of six eyes was that of complete tractional retinal detachment, uncorrectable, despite laser and vitrectomy/lensectomy intervention.Two of six eyes,(33%), had no abnormal ultrasonic findings; neither reached threshhold, thus, negating the need for retinal laser or vitrectomy.
Cribside ultrasonography can be used to examine neonates with stage 1 ROP for the presence of peripheral retinal traction in zone 1 ROP, that may be undetectable by ophthalmoscopy, and may indicate the onset of progressive retinal detachment, at a time when the remaining retina is still attached.These ultrasonic signs of retinal traction may identify those eyes that would benefit from the earlier timing of vitrectomy for zone 1 ROP retinal detachment.
