Methods
The data is derived from the PHOTO-ROP Study material. The design9 and results10 of this prospective, multicenter, masked, internet-based clinical trial were reported earlier. The study protocol and informed consent were approved by individual institutional review boards at each participating center. One of the secondary aims of the study was to document the evolution of posterior ROP-related retinal detachments.
Briefly, eyes were examined using the PHOTO-ROP standard imaging protocol.9 Digital
Results
All eyes showed initial reduction of plus disease after treatment. After a mean of 9.5 days (range, seven to 14 days) all 10 eyes showed a recurrence of plus disease and retinal detachment. Retinal detachments predominantly were located nasally. The mean postconceptual age at which retinal detachment was first noted was 41.42 ± 3.6 weeks (range, 36 to 47.29 weeks). Flat preretinal vitreous organization was apparent in all 10 eyes, without significant transvitreal components. FIGURE 1, FIGURE 2,
Discussion
Eyes with zone 1 ROP often fare poorly.1, 2, 3, 4, 5, 6, 7, 8 Aggressive posterior ROP is characterized by a broad, flat, neovascular syncytium in zone 1.2 This is opposed to the typical elevated extraretinal neovascular proliferation arising at 90 degrees to the retina posterior to the ROP ridge, typical of stage 3 ROP in zones 2 and 3.
The explanations for why such flat neovascular changes occur currently are speculative. Recently, a distinct vasculogenic stage of development has been

2018, Progress in Retinal and Eye ResearchCitation Excerpt :Early vitreous surgery has been advocated but the results remain poor especially if fibrovascular growth has already reached the vitreous base when surgery is performed (Azuma et al., 2013). After laser for AP-ROP, there may be early decrease in posterior vascular abnormality, but the retinopathy can reappear and progress rapidly to intractable retinal detachment (Vinekar et al., 2008). A second session of laser to fill in areas of regression of flat neovascularization produced by a first session will produce fewer haemorrhages and less fibrosis post treatment than a single session of heavier laser (Vinekar et al., 2015a).
