Insights
Intravitreal anti-VEGF therapy is effective for retinopathy of prematurity (ROP), offering high regression rates and preserving peripheral vision. Laser photocoagulation provides high initial success but ablates more retina, potentially increasing myopia risk.
Area of Science:
- Ophthalmology
- Neonatology
- Vascular Biology
Background:
- Retinopathy of prematurity (ROP) is a significant cause of infant blindness, particularly in premature infants.
- ROP is a vascular disorder affecting the developing retina.
Purpose of the Study:
- To compare the efficacy and outcomes of intravitreal anti-VEGF therapy versus laser photocoagulation for ROP treatment.
- To evaluate treatment decisions based on ROP stage, zone, and risk-benefit analysis.
Main Methods:
- Prospective comparative cohort study involving 1188 screened infants.
- Treatment groups included intravitreal anti-VEGF (67 infants) and laser photocoagulation (10 infants).
Main Results:
- Intravitreal anti-VEGF achieved 96.82% anatomical regression, with 3.17% requiring adjunctive laser.
- Laser photocoagulation showed 100% primary anatomical success but ablates more peripheral retina.
- Aggressive posterior ROP (APROP) responded well to anti-VEGF, though complications like cataract and retinal detachment occurred, necessitating follow-up.
Conclusions:
- Anti-VEGF therapy is effective for Type 1 ROP, offering high regression rates and superior peripheral retinal sparing compared to laser.
- Laser photocoagulation has high initial success but poses a greater risk of myopic shift.
- Individualized treatment decisions considering zone, stage, and risk-benefit are crucial for optimal ROP management.
Abstract:
Retinopathy of prematurity (ROP) is a vascular disease of the developing retina and a key, but mostly avoidable, cause of blindness in infants (especially preterm and very low birth weight infants). Hence in this prospective comparative cohort study of 1188 screened infants, 77 infants needed treatment; 67 of them received intravitreal anti-VEGF and 10 received laser photocoagulation. Intravitreal anti-VEGF has shown anatomical regression in 96.82 of treated eyes; of which 3.17% required auxiliary laser and primary laser anatomical success was 100% but ablate the peripheral retina more and theoretically presents a greater risk of myopic shift. Aggressive posterior ROP (APROP) which was observed in 5.5 percent of the cohort responded to anti -VEGF in most cases, although isolated but serious complications were identified including cataract and retinal detachment, which demonstrates the importance of careful long-term follow-up. Thus Anti-VEGF was also useful in Type 1 ROP, but the current study also makes progress in demonstrating in a clinical setting that anti-VEGF can yield high regression with low adjunctive laser and superior peripheral retinal sparing, as opposed to laser which has a little higher one-time anatvi-success, indicating that a customized, zone- and stage-based, risk-benefit-driven decision on which therapy to use in any infant is possible.
