Evolution of Retinal Detachment in Posterior Retinopathy of Prematurity: Impact on Treatment Approach

Purpose

To provide insight into the course of retinal detachment in eyes with aggressive posterior retinopathy of prematurity (APROP).

Design

Prospective, multicenter, masked clinical trial.

Methods

Multicenter trial based on serial digital photographic imaging detailing five infants (in the Photographic Screening for Retinopathy of Prematurity [PHOTO-ROP] Study) in whom bilateral retinal detachment developed during the course of the study.

Results

Retinal detachment developed in both eyes (n = 10) of all five infants despite peripheral retinal laser ablation. The mean birth weight was 651.4 ± 45.30 g (range, 601 to 718 g), and the mean gestation was 26.75 ± 0.96 weeks (range, 24 to 26 weeks). APROP (flat neovascularization) was present in all eyes at the time of treatment. Laser treatment was performed at a mean postconceptual age of 37.25 ± 1.8 weeks (range, 35 to 39.57 weeks). Plus disease resolved initially and then recurred (mean, 9.5 days) with progression to retinal detachment; the mean postconceptual age at the time of retinal detachment was 41.42 ± 3.6 weeks (range, 36 to 47.29 weeks). Untreated avascular retina became visible with regression of flat preretinal neovascularization. All 10 eyes showed preretinal vitreous organization (most prominent nasally) along the retinal surface without significant transvitreal components.

Conclusions

Eyes with APROP may follow an atypical course after laser ablation. Such eyes may still fare poorly, even when plus disease wanes. Additional laser to avascular retina may be necessary after the overlying flat stage 3 neovascularization regresses. The absence of obvious fibrosis at the time of laser should provide no reassurance as to reduced probability of progression to retinal detachment.

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

    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).
