Insights
Intravitreal bevacizumab monotherapy for retinopathy of prematurity can cause thread-like vitreous condensation. This finding may predict further regression and retinal vascularization in infants.
Area of Science:
- Ophthalmology
- Neonatology
- Vascular Biology
Background:
- Retinopathy of prematurity (ROP) is a leading cause of childhood blindness.
- Anti-VEGF therapy, including intravitreal bevacizumab (IVB), is a common treatment for ROP.
- Understanding treatment-related changes is crucial for patient management.
Purpose of the Study:
- To report a specific clinical finding after IVB monotherapy for ROP.
- To describe the characteristics and implications of vitreous changes observed post-IVB.
Main Methods:
- Retrospective case series of five premature infants.
- Single-dose intravitreal bevacizumab (IVB) monotherapy without laser therapy.
- Observation of clinical course and vitreous changes.
Main Results:
- Localized vitreous syneresis and linear fibrotic vitreous condensation observed 8.2 weeks post-IVB.
- This finding occurred in 15.5% of injections.
- All patients showed further regression and complete retinal vascularization.
Conclusions:
- Thread-like vitreous condensation with liquefaction may be linked to involutional ROP and anti-VEGF therapy.
- This vitreous change may predict further regression and retinal vascularization.
- IVB monotherapy demonstrated a successful treatment response without complications.
Purpose:
Reporting a special clinical finding after intravitreal bevacizumab monotherapy for retinopathy of prematurity.
Methods:
In a retrospective case series, the clinical courses of five premature infants with similar vitreous changes after a single dose of intravitreal bevacizumab (IVB) injection without additional laser therapy were reported.
Results:
The mean post-conceptional age at IVB injection was 39.8 ± 2.2 (range 37-43) weeks. Localized vitreous syneresis and linear fibrotic vitreous condensation occurred 8.2 ± 2.3 weeks after IVB monotherapy in our patients (15.5% of injections). The mean last post injection visit was 61.6 ± 5.3 weeks (post-conceptional age). Further regression and complete retinal vascularization occurred in all patients.
Conclusions:
Thread-like vitreous condensation with localized vitreous liquefaction may be related to involutional ROP disease itself, combined to anti VEGF therapy and may be a predictor factor for further regression and retinal vascularization. The case series describes a successful response to anti-VEGF monotherapy with no further complications.
