“…In contrast to other studies [2,5], our population was composed entirely of infants with recently diagnosed stage-5 disease. Those with cicatricial disease or long-standing detachment were excluded from the study.…”

“…A review of these reports shows considerable variability in both the B-scan and Ascan US features (although the latter have been described less frequently) of these cases, even when identical pathological conditions are present. In addition, there is often a discrepancy between US findings and the descriptions based on ophthalmoscopic or intraoperative findings [5]. In many cases of funnel-shaped stage-5 detachments, the US image is characterized by the presence of echogenic retrolental structures, but there is no evidence of the posterior portions of the detached retina [5,8].…”

“…The ultrasonographic (US) characteristics of severe forms of retinopathy of prematurity (ROP, stages 4-5) have been analyzed by ophthalmologists specialized in ophthalmic ultrasound [1,2,5,8] and by vitreoretinal surgeons and pediatric ophthalmologists without any particular training in this type of imaging [3,4,7,9]. A review of these reports shows considerable variability in both the B-scan and Ascan US features (although the latter have been described less frequently) of these cases, even when identical pathological conditions are present.…”

Background: In preterm infants with severe retinopathy of prematurity, there is often a discrepancy between ophthalmic ultrasound findings and the ophthalmoscopic and/or intraoperative aspect of the eye. Methods: Six preterm infants (8 eyes) with stage-5 retinopathy of prematurity were examined with standardized ophthalmic echography (A and B scans) shortly before undergoing open-sky vitrectomies. Sonographic findings were evaluated according to four A-scan and four B-scan criteria used to diagnose retinal detachment in adults and compared to intraoperative findings. Results: Although the retinal detachments and vitreal proliferation found in all 8 eyes at surgery were almost identical, the sonographic aspects varied widely: 3/8 satisfied most of the criteria used in adults, 3/8 presented two criteria only and the remaining 2 were negative for all criteria used. Conclusion: The variability in the ultrasonographic aspects of these preterm eyes may depend on the degree of maturity of the preterm retina at the time of examination, with more mature retinas presenting greater reflectivity and therefore greater visibility in the sonographic exam.

“…To my knowledge there are still only seven papers on this subject and a few statements published here and there. Five of the seven papers were published by clinicians particularly interested in echography and echographers [19,20,21,24,25] and the other two by clinicians belonging to groups having extensive surgical experience on ROP [22,23]. It would appear to be very simple to gather data from such a small sample, but it is just the opposite because there are some considerable discrepancies among the different authors' findings.…”

The authors, before starting the discussion about ultrasound findings in infants with ROP, present a review of the history of ultrasound in this disease. Early A-scan reports are mentioned while the B-scan literature from 1984 to 1988, consisting of seven papers, is reviewed extensively. The most important echo patterns in the various stages of the disease are described along with the most intriguing ones. There is disagreement as to whether it is always possible to show by echography if the retina is in place or not. This is due to the fact that the acoustic properties of the retina seem sometimes to change as time goes by and is quite independent of any technical difficulties which are still very great and the know-how of the examiner.
