Stage 5 retinopathy of prematurity: An update.

ABSTRACT: Retinopathy of prematurity (ROP) is one of the most common causes of preventable blindness in children. In spite of the availability of various treatment options, and favorable results with timely intervention, many infants present to the ophthalmologists in the advanced end stage of the disease due to lack of awareness especially in the developing nations. This blinding or Stage 5 of ROP presents with total retinal detachment and has to be managed surgically. The surgical techniques for Stage 5 ROP are unique and demanding. The successful anatomical results after surgery are only seen in 20%-50% of cases. In spite of a successful anatomical result, the visual outcome may be slow and limited. The use of newer pharmacological adjuncts has shown promising results. Because of heterogeneity of presentation of the disease severity, a genetic predisposition has also been proposed. A concerted effort from the pediatricians, ophthalmologists, and healthcare workers is required to establish effective screening and treatment guidelines to prevent blindness due to ROP. Till then surgical management has to be done. Parents must be educated regarding the limited visual benefits of surgery and the need for prolonged follow-up. This review gives a comprehensive overview of the pathogenesis, clinical aspects, surgical interventions, and their outcomes and future prospects of Stage 5 ROP.

Project description:BackgroundRetinopathy of prematurity is a leading cause of childhood blindness worldwide. Peripheral retinal ablation with conventional (confluent) laser therapy is destructive, causes complications, and does not prevent all vision loss, especially in cases of retinopathy of prematurity affecting zone I of the eye. Case series in which patients were treated with vascular endothelial growth factor inhibitors suggest that these agents may be useful in treating retinopathy of prematurity.MethodsWe conducted a prospective, controlled, randomized, stratified, multicenter trial to assess intravitreal bevacizumab monotherapy for zone I or zone II posterior stage 3+ (i.e., stage 3 with plus disease) retinopathy of prematurity. Infants were randomly assigned to receive intravitreal bevacizumab (0.625 mg in 0.025 ml of solution) or conventional laser therapy, bilaterally. The primary ocular outcome was recurrence of retinopathy of prematurity in one or both eyes requiring retreatment before 54 weeks' postmenstrual age.ResultsWe enrolled 150 infants (total sample of 300 eyes); 143 infants survived to 54 weeks' postmenstrual age, and the 7 infants who died were not included in the primary-outcome analyses. Retinopathy of prematurity recurred in 4 infants in the bevacizumab group (6 of 140 eyes [4%]) and 19 infants in the laser-therapy group (32 of 146 eyes [22%], P=0.002). A significant treatment effect was found for zone I retinopathy of prematurity (P=0.003) but not for zone II disease (P=0.27).ConclusionsIntravitreal bevacizumab monotherapy, as compared with conventional laser therapy, in infants with stage 3+ retinopathy of prematurity showed a significant benefit for zone I but not zone II disease. Development of peripheral retinal vessels continued after treatment with intravitreal bevacizumab, but conventional laser therapy led to permanent destruction of the peripheral retina. This trial was too small to assess safety. (Funded by Research to Prevent Blindness and others; ClinicalTrials.gov number, NCT00622726.).

Project description:ImportanceProgression of retinopathy of prematurity (ROP) to stage 4 may require surgical intervention. The partial retinal detachment of stage 4 ROP may involve the fovea (stage 4B ROP) or may not (stage 4A ROP). This determination has heretofore been based on indirect ophthalmoscopy and documented with color fundus photography.ObjectiveTo investigate optical coherence tomography (OCT) features of eyes with stage 4 ROP and compare them with indirect ophthalmoscopy findings and grading of photographs.Design, setting, and participantsIn this study, research and clinical medical records of 15 infants with clinically diagnosed stage 4 ROP were retrospectively reviewed. Infants were treated at an academic center from May 2011 to January 2018.Main outcomes and measuresReview of OCT images for the presence and foveal involvement of retinoschisis, retinal detachment, and/or vitreomacular traction masked to indirect ophthalmoscopy findings.ResultsOf the 15 included infants, 9 (60%) were male, the mean (SD) gestational age at birth was 23.9 (1.1) weeks, and the mean (SD) postmenstrual age at surgery was 42.4 (4.9) weeks. A total of 21 eyes were analyzed, of which 19 had adequate OCT imaging. Optical coherence tomography imaging extended to the retinal midperiphery but did not cover the entire region of possible detachment in each eye. Among these eyes, 7 eyes had peripheral retinoschisis without retinal detachment or foveal involvement, 5 eyes had peripheral retinoschisis and retinal detachment without foveal involvement, 7 eyes had either retinoschisis or retinal detachment involving the fovea, and 2 eyes had poor OCT signal owing to high retinal detachment.Conclusions and relevanceHandheld OCT imaging is useful in clinical evaluation of stage 4 ROP to determine foveal involvement and differentiate retinal detachment and retinoschisis. Many infants diagnosed as having stage 4A ROP had retinoschisis without OCT evidence of retinal detachment. This group of infants may represent a substage of stage 4A ROP, ie, stage 4A-schisis by OCT. These findings suggest handheld OCT imaging may be useful in the clinical evaluation of stage 4 ROP. Further investigations are needed to determine if this subgroup portends a different prognosis and if this observation should alter future clinical practice.
