Diode laser photocoagulation to the vascular retina for progressively advancing retinopathy of prematurity
Insights
Diode laser photocoagulation posterior to the ridge effectively treated advanced retinopathy of prematurity (ROP) in infants. This treatment showed promising results, including total regression in some eyes and maintained vision in others with residual detachment.
Area of Science:
- Ophthalmology
- Neonatal Medicine
- Medical Technology
Background:
- Retinopathy of prematurity (ROP) is a leading cause of childhood blindness.
- Conventional laser treatments for ROP can have limitations and side effects.
- Advanced stages of ROP, particularly stage 3+ and 4A, present significant treatment challenges.
Purpose of the Study:
- To evaluate the efficacy of diode laser photocoagulation applied posterior to the fibrovascular ridge in ROP.
- To assess this treatment as an alternative or adjunct therapy for ROP.
- To determine outcomes in eyes with previously failed anterior laser treatments.
Main Methods:
- Diode laser photocoagulation was performed posterior to the fibrovascular ridge.
- Treatment was applied to eyes with stage 4a ROP and advancing stage 3+ ROP.
- Included eyes with prior unsuccessful laser treatment anterior to the ridge.
Main Results:
- Six eyes achieved total regression of ROP.
- Two eyes showed flat maculae with residual peripheral tractional detachment but maintained vision.
- The treatment was applied to a total of eight eyes across five infants.
Conclusions:
- Diode laser photocoagulation posterior to the ridge appears to be a viable treatment option for late-stage ROP.
- This technique may be beneficial in cases of ROP refractory to conventional anterior laser treatment.
- Preliminary findings suggest potential for vision preservation in challenging ROP cases.
Aims:
To estimate the effectiveness of diode laser photocoagulation of the retina posterior to the ridge in eyes with retinopathy of prematurity (ROP).
Methods:
Diode laser photocoagulation was applied posterior to the fibrovascular ridge in stage 4a ROP in six eyes of four infants and in advancing stage 3+ in two eyes of one infant. Seven eyes had previously been unsuccessfully treated with diode laser photocoagulation anterior to the ridge.
Results:
Six eyes of four children had total regression, two eyes of two children had flat maculae with residual peripheral tractional detachment and maintained vision.
Conclusion:
These preliminary results indicate that diode laser photocoagulation posterior to the ridge may be a useful treatment in late stage 3 and stage 4A ROP following failed laser treatment to the avascular retina in threshold stage 3 disease.
