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
Introduction: Myopia usually commences during primary school and progresses until the mean age of 16 years. Topical low-dose (0.01%) atropine eye-drop appears to be safe and efficacious for myopia control in children. However, in some cases, a higher concentration of atropine is required in some cases because low-dose atropine treatment is not effective. Methods: This is a retrospective study among young myopic children between 5 and 15 years with myopia progression > 0.50 D/year. We selected patients treated with low-dose atropine (0.01%) eye-drops for 12 months and conducted a comparative analysis of the group with good responder and poor responder. Patients were classified as good responders if spherical equivalent refractive error (SE) progression was ⩽ 0.50 D after 12 months of treatment and poor responders if SE progression > 0.50 D. The prognostic factors before and after treatment were analyzed in two groups. Results: A total of 68 eyes were included. Low-dose (0.01%) atropine eye-drops have a good treatment response in 54% of patients. In the good responder group ( n = 37), the mean rate of myopia progression after 12 months of treatment (0.36 ± 0.17 D) was significantly slower compared with the baseline progression ( p < 0.001). Good responders have smaller changes in axial length (AL) elongation and SE than poor responders ( p < 0.001). The only adverse event was temporary near vision difficulty (10%), photophobia (10%), and mild pupil dilation (30%). Discussion: The AL elongation is an important indicator for monitoring the treatment response. Children with a family history of myopia at a young age may not respond well to low-dose (0.01%) atropine eye-drops. In these cases, increasing the concentration of atropine eye-drops should be considered.
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.
