Large Spot Laser for Treatment of Retinopathy of Prematurity
Insights
Large spot laser treatment for retinopathy of prematurity (ROP) significantly reduces procedure time in zones I and II. This method offers a faster, effective alternative for ROP treatment with comparable outcomes and no increased myopia.
Area of Science:
- Ophthalmology
- Pediatric Medicine
- Laser Surgery
Background:
- Retinopathy of prematurity (ROP) is a leading cause of blindness in premature infants.
- Standard laser photocoagulation for ROP can be time-consuming and painful.
- Optimizing treatment protocols for ROP is crucial for improving infant outcomes.
Purpose of the Study:
- To compare the efficacy and safety of large spot versus standard spot laser photocoagulation for treating retinopathy of prematurity (ROP).
- To evaluate treatment duration, pain scores, disease regression, and refractive error changes between the two laser spot sizes.
Main Methods:
- Eighty eyes of 40 infants with bilateral type 1 ROP were randomized to receive laser photocoagulation using either standard or large spot laser indirect ophthalmoscopy.
- Treatment time and Premature Infant Pain Profile (PIPP) scores were recorded during the procedure.
- Disease regression and refractive errors were assessed during follow-up.
Main Results:
- Large spot laser significantly reduced treatment duration by 32% in zone I (P = .005) and 63.4% in zone II (P = .0006).
- Pain scores were comparable between groups, with moderate-to-severe pain observed throughout.
- No statistically significant difference in the mean change of refractive error (myopia) was found between the groups post-treatment.
Conclusions:
- Large spot laser photocoagulation is an effective alternative for ROP treatment, offering a significantly reduced procedure time.
- The large spot laser provides faster treatment and potentially less overall pain duration with similar disease regression and no increased risk of myopia.
- This technique can be implemented without specialized training, making it a valuable option for ROP management.
Background And Objective:
To compare large spot versus standard spot laser for treatment of retinopathy of prematurity (ROP).
Patients And Methods:
Eighty eyes of 40 infants with bilateral type 1 ROP were randomized for laser photocoagulation using laser indirect ophthalmoscope with either standard spot or large spot size laser. During the procedure, total time taken and Premature Infant Pain Profile (PIPP) scores were noted. Regression of disease and refractive error were noted on follow-up.
Results:
The infants were randomized into two groups. All infants in both groups had regression of ROP. Large spot laser significantly reduced total treatment duration in zone I by 32% (P = .005) and zone II by 63.4% (P = .0006). Moderate-to-severe pain occurred in PIPP scores in both groups throughout the procedure (under topical anesthesia) and was comparable between the groups. Mean change in refractive error (myopia) from pre-laser (2.090 diopters [D] ± 1.345 D) to 3 months' post-laser (2.465 D ± 1.399 D) was not statistically significant between the groups.
Conclusions:
Large spot laser significantly reduced total duration of laser treatment in zone I/II ROP. Large spot laser is a useful alternative for treatment of ROP in terms of faster procedure, lesser total duration of pain, and similar regression profile. It does not cause additional myopia and can be performed without additional training. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:e233-e239.].
