Purpose: The characteristics of pediatric dermoid cyst patients.Methods: This was a retrospective chart review of 64 dermoid cyst patients (65 eyes) aged < 18 years.Results: Limbal dermoids and conjunctival dermolipomas were observed in 49 and 16 eyes (48 and 16 patients), respectively. Limbal dermoids were more common in the left eye (61%), particularly on the inferotemporal side (80%). Three (6%) of the patients were diagnosed with Goldenhar syndrome. The horizontal diameter (3.76 ± 1.30 mm) was greater than the vertical diameter (3.74 ± 1.30 mm). Most of the lesions were yellow (35.2%) in color, mildly elevated (n = 19, 55.9%), and not visible when the eyes were closed. The mean best corrected visual acuity was 0.8 ± 0.2 in 23 patients, with mean astigmatism and mean corneal astigmatism values of -2.1 ± 2.2 diopters (D) and -2.0 ± 1.1 D, respectively. None of the conjunctival dermolipoma patients had any ocular history. The left eye (75%), particularly the temporal and superiotemporal conjunctival fornix, was the most commonly affected site. The mean best corrected visual acuity was 0.9 ± 0.0 in seven patients, with an average astigmatism of -0.3 ± 0.2 D.Conclusions: Dermoid cysts are congenital benign tumors that may be associated with congenital diseases. They vary in size, location, color, and extent of invasion, and may cause functional problems, such as astigmatism and amblyopia. Therefore, timely surgical treatment is desirable.

Purpose: To analyze changes in astigmatism and visual acuity in pediatric patients with limbal dermoid before and after surgery.Methods: Twenty-five pediatric patients (7 male, 18 female) diagnosed with limbal dermoid from March 2018 to February 2022 were included. We analyzed best corrected visual acuity and astigmatism using cycloplegic refraction, automated keratometry, and topography before and after surgery.Results: In cycloplegic refraction and automated keratometry, postoperative astigmatism did not decrease significantly (<i>p</i> = 0.53 and <i>p</i> = 0.38, respectively). Topography showed a significant decrease in corneal astigmatism from 3.6 ± 2.8 diopters (D) to 2.7 ± 1.8 D (<i>p</i> < 0.05) and in irregular astigmatism from 3.7 ± 2.2 D to 2.5 ± 1.5 D (<i>p</i> < 0.001). Significant decreases were observed in the corneal irregularity index from 0.14 ± 0.10 mm to 0.08 ± 0.47 mm (<i>p</i> < 0.001) and in the index of surface variance from 60.56 ± 41.02 to 35.00 ± 16.00 (<i>p</i> < 0.001). There was a statistically significant improvement in best corrected visual acuity from logarithm of minimal angle of resolution (logMAR) 0.18 to logMAR 0.07 (<i>p</i> < 0.05).Conclusions: Surgery for limbal dermoid significantly reduced irregular astigmatism and improved best-corrected visual acuity. It is suggested that achieving visual development through active amblyopia treatment after surgery is important.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
