To assess the tolerability and outcomes of laser treatment for retinopathy of prematurity (ROP) under sub-tenon anaesthetic with oral or rectal sedation using a reliable, multidimensional, and internationally accepted tool for assessment of neonatal pain. ⋯ Pain scores were available in 19 of the 27 babies treated under sub-tenon anaesthesia. The mean pain score during treatment was 2.7 (SD ± 1.7, range 0.5-6.2). There was no statistically significant correlation between the mean pain score and duration of treatment (Spearman correlation coefficient (ρ) = 0.31; P = 0.09), number of laser burns (ρ = 0.32; P = 0.09), or post-menstrual age of the baby at the time of treatment (ρ = 0.38; P = 0.052). Treatments performed under sub-tenon anaesthesia were as successful as those performed under intravenous sedation. The mean pain scores during laser treatment under sub-tenon anaesthesia in our study were lower than those previously reported during ROP screening or heel-stick procedure.Conclusion Our study demonstrated that sub-tenon anaesthesia with oral or rectal sedation provides sufficient pain control for laser treatment for ROP without the need or risks of intravenous sedation and intubation.
