Efficacy comparison of multipoint and single point scanning panretinal laser photocoagulation in non-proliferative diabetic retinopathy treatment.
Background: Non-proliferative diabetic retinopathy (NPDR) poses a significant challenge in diabetes management due to its microvascular changes in the retina. Laser photocoagulation, a conventional therapy, aims to mitigate the risk of progressing to proliferative diabetic retinopathy (PDR).
Aim: To compare the efficacy and safety of multi-spot vs single-spot scanning panretinal laser photocoagulation in NPDR patients.
Methods: Forty-nine NPDR patients (86 eyes) treated between September 2020 and July 2022 were included. They were randomly allocated into single-spot (n = 23, 40 eyes) and multi-spot (n = 26, 46 eyes) groups. Treatment outcomes, including best-corrected visual acuity (BCVA), central macular thickness (CMT), and mean threshold sensitivity, were assessed at predetermined intervals over 12 months. Adverse reactions were also recorded.
Results: Energy levels did not significantly differ between groups (P > 0.05), but the multi-spot group exhibited lower energy density (P < 0.05). BCVA and CMT improvements were noted in the multi-spot group at one-month post-treatment (P < 0.05). Adverse reaction incidence was similar between groups (P > 0.05).
Conclusion: While energy intensity and safety were comparable between modalities, multi-spot scanning demonstrated lower energy density and showed superior short-term improvements in BCVA and CMT for NPDR patients, with reduced laser-induced damage.
期刊介绍：
The WJD is a high-quality, peer reviewed, open-access journal. The primary task of WJD is to rapidly publish high-quality original articles, reviews, editorials, and case reports in the field of diabetes. In order to promote productive academic communication, the peer review process for the WJD is transparent; to this end, all published manuscripts are accompanied by the anonymized reviewers’ comments as well as the authors’ responses. The primary aims of the WJD are to improve diagnostic, therapeutic and preventive modalities and the skills of clinicians and to guide clinical practice in diabetes. Scope: Diabetes Complications, Experimental Diabetes Mellitus, Type 1 Diabetes Mellitus, Type 2 Diabetes Mellitus, Diabetes, Gestational, Diabetic Angiopathies, Diabetic Cardiomyopathies, Diabetic Coma, Diabetic Ketoacidosis, Diabetic Nephropathies, Diabetic Neuropathies, Donohue Syndrome, Fetal Macrosomia, and Prediabetic State.
