Introduction: Recently in South Korea, there are increasing number of young adults undergoing orthokeratology treatment for myopia control. They prefer orthokeratology treatment more than wearing spectacles or having a refractive surgery for several reasons. However, there is little research on the effect of orthokeratology treatment on choroids. Objective: The aim of this study was to analyze the change in choroidal thickness (CT) in the horizontal axis in young myopic adults after orthokeratology treatment. Methods: This was a retrospective research among young myopic patients (−1.0 to −5.0 diopters) aged 19–29 years (n = 36; 23.6 ± 2.5 years). We selected patients who were treated with orthokeratology for 12 months. CT values of the horizontal axis near the fovea before and after orthokeratology treatment were analyzed using optical coherence tomography. The value was measured at the beginning of treatment and at 3, 6, and 12 months after orthokeratology treatment. Three regional areas of choroid on the horizontal plane including fovea were analyzed. Result and Conclusions: In the beginning of orthokeratology treatment, CT of the horizontal axis was 248.9 ± 45.7 μm in the temporal region, 259.9 ± 55.3 μm in the macular region, and 219.2 ± 46.4 μm in the nasal region. Three months after orthokeratology treatment, thickness values of choroids in the 3 divided areas increased significantly (p < 0.05). Mean CT at 6 or 12 months after orthokeratology treatment was greater than before ortho­-keratology treatment. CT increased after 3 months of orthokeratology treatment in each regional area. In young myopic adults, CT in nasal area was thinner than that in foveal or temporal area before treatment. CT recovered to near baseline when it was observed for more than 6 months after orthokeratology treatment.

Purpose: This study aims to present the therapeutic outcomes of benign eyelid margin tumors treated with laser ablation, offering an alternative approach to traditional shaving biopsy. Methods: In all patients, tumors were eliminated through either laser ablation or shaving biopsy. Comparative analysis was conducted between two patient groups: the laser-assisted ablation group (Group 1) and the shaving excision surgery group (Group 2). A total of 66 patients with 67 benign eyelid margin tumors were retrospectively included in this study (2019-2023). Thity-four cases underwent laser ablation, and 33 cases were subjected to shaving excision biopsy. Postoperatively, histologic confirmation was obtained in 11 out of the 33 cases that underwent shaving excision. Results: In Group 1, no functional or cosmetic complications were observed. The wound margin was clear after laser-assisted ablation in all cases. In Group 2, there was one instance of eyelid notching, loss of cilia, and two pigmentations. No wound infections were reported. The average wound epithelialization duration was 3.3 weeks in Group 1, significantly faster than 4.2 weeks in Group 2 (p < .01). The average lesion size was 3.0 x 2.9 mm in Group 1, significantly smaller than 3.5 x 3.4 mm in Group 2 (p < .05). No recurrences were observed during the follow-up period. Conclusions: Laser ablation for small benign eyelid margin tumors may be a favorable alternative to shaving excision biopsy surgery. All patients were satisfied with the cosmetic result. There was no definitive postoperative or intraoperative complication during or after laser application.

PURPOSE: To report the treatment response of benign eyelid margin tumors with a laser ablation as an alternative to shaving biopsy METHODS: Fifty-eight patients with 61 benign tumors of the eyelid margin were included in this study retrospectively (2019_2022). In all patients, the tumor was eliminated by laser ablation or shaving biopsy. Twenty-nine cases were eliminated by laser ablation and 28 cases were removed by shaving excision biopsy. Comparative analysis was done between the laser-assisted ablation patients group: Group 1 and shaving excision surgery patients group: Group 2. Postoperatively, histologic confirmation was obtained in 11 patients of the 28 shaving excision removal cases. RESULTS: There was no functional or cosmetic complication in group 1. The wound margin was clear after laser-assisted ablation in all cases. There was one notching of the eyelid, loss of cilia, and two pigmentations in group 2. No infections of the wounds occurred. The average wound epithelialization duration was 3.3 weeks in group 1, significantly faster than 4.2 weeks in group 2. No recurrences occurred during the follow-up period. CONCLUSIONS: Laser ablation of benign eyelid margin tumors may good alternative option regarding shaving excision biopsy surgery. All patients were satisfied with the cosmetic result. There was no definitive postoperative or intraoperative complication during or after laser application.
