Purpose: We present a case of equatorial and posterior zonular weakness observed during cataract surgery in both eyes with no prior history of trauma or surgery.Case summary: A 73-year-old woman visited out clinic and reported decreased visual acuity. She was found to have a best corrected visual acuity of 0.5 in both eyes. Cataracts were noted during a slit lamp examination and cataract surgery was subsequently performed. During the left eye surgery, although there was no evident weakening during the anterior capsulotomy, the equatorial and posterior zonules were damaged during phacoemulsification. This led to consistent aspiration of the equatorial and posterior capsule (PC) into the phaco-handpiece tip during epinucleus and cortex removal. The PC eventually ruptured necessitating anterior vitrectomy and a 3-piece intraocular lens insertion into the ciliary sulcus. Two weeks later, the right eye surgery encountered similar challenges in removing the epinucleus and cortex. The surgery was completed successfully by elevating the irrigation bottle, frequently injecting an ophthalmic viscoelastic device (OVD), and removing the remaining lens material using a bimanual irrigator/aspirator. Conclusions This case highlights that equatorial and posterior zonular weakness can occur in the absence of trauma or prior to surgery. To manage such cases, it is advisable to elevate the irrigation bottle height, continuously inject OVD during surgery, and use a bimanual irrigator/aspirator.

Purpose: To evaluate the characteristics, anatomical success rate, and factors that may affect the anatomical success of rhegmatogenous retinal detachment in patients in their 20s. Methods: We retrospectively analyzed the medical records of patients aged 20-29 years who underwent surgery for rhegmatogenous retinal detachment from January 2018 to December 2022. We examined factors such as sex, age, duration of illness, preoperative best corrected visual acuity, presence of underlying diseases, proliferative vitreoretinopathy, lattice degeneration, macular involvement, extent of retinal detachment at diagnosis, axial length, and myopia level to explore their impact on surgical outcomes. Results: The study included 122 eyes. The mean age was 23.81 ± 2.82 years, and the average sphere power was -5.80 ± 3.71 diopters (D). The percentage of eyes with a refraction of ≤ -6.0 D came to 44.3% (54/122), and with ≤ -4.0 D it amounted to 72.1% (88/122). The average logarithm of the minimum angle of resolution (logMAR) best corrected visual acuity improved significantly from 0.52 ± 0.68 before surgery to 0.28 ± 0.45 after surgery. The primary surgical success rates were 92.0% for scleral buckling, 88.9% for vitrectomy, and 92.3% for combined scleral buckling and vitrectomy, with no significant factors related to anatomical success identified. Conclusions There was a high prevalence of moderate to severe myopia among patients in their 20s with rhegmatogenous retinal detachment. However, no statistically significant correlation was found between the degree of myopia and anatomical success. Both functional and anatomical outcomes were generally favorable in these patients.

Background and Objectives: Pediatric chronic rhinosinusitis (CRS) significantly affects children’s quality of life and learning abilities. This study aimed to evaluate the postoperative outcomes in pediatric patients who underwent functional endoscopic sinus surgery (FESS) for CRS. Methods: A retrospective review was conducted on pediatric patients who underwent FESS for CRS at 11 university hospitals. The inclusion criteria were patients under 20 years old with bilateral disease who were operated on between January 2005 and December 2021. The data collected included demographics, clinical history, blood tests, preoperative computed tomography, and preoperative and postoperative symptom control. The Kruskal-Wallis and Fisher exact tests were used to compare the quantitative and qualitative data, respectively. Results: In total, 213 patients were enrolled. The mean age was 13.4±3.0 years, and 145 (68.1%) were male. One hundred sixty-four patients (77.0%) had nasal polyps and 33 patients (15.5%) underwent revision FESS. The preoperative symptoms, in order of prevalence, included nasal obstruction (87.8%), rhinorrhea (71.8%), a sense of postnasal drip (58.2%), hyposmia (44.6%), cough (24.4%), and facial fullness (18.3%). These symptoms were significantly alleviated for up to 3 years after surgery (p<0.001). At the time of the last follow-up, 121 patients (56.8%) were controlled, 80 (37.6%) were partly controlled, and 12 (5.6%) were uncontrolled. Patients in the uncontrolled group had higher Lund-Mackay scores, longer follow-up durations, and more instances of revision surgery compared to those in the controlled and partly controlled groups. When age was categorized into three groups, those aged 16 years or older tended to have lower Lund-Mackay scores and better control. Conclusion FESS significantly improves both the postoperative symptoms and the long-term quality of life in pediatric CRS patients. Better symptom control is associated with older age and a lower disease burden.

Background: Fluorescein angiography (FA) is a diagnostic procedure that is crucial for conditions such as age-related macular degeneration and diabetic retinopathy, and due to its importance, the use of conventional and wide-angle FA (wide FA) is on the rise. This study aimed to analyze the annual trends of conventional and wide FA and the trends of healthcare institutions performing these examinations in Korea. Methods: This retrospective study examined data from the Health Insurance Review and Assessment Service’s Health and Medical Big Data Open Portal. We investigated the number of patients who underwent conventional and wide FA procedures performed in Korea from 2014 to 2023, categorized by age group and type of healthcare facility. Additionally, trends in healthcare expenditures were analyzed. Results: The number of patients undergoing conventional FA consistently declined, while those receiving wide FA increased steadily, keeping the overall patient count relatively stable.Healthcare costs related to conventional FA gradually decreased, whereas expenses for wide FA rose steadily, contributing to an increase in total medical expenses. Analysis of ten-year age intervals revealed that patients in their 60s were the most frequent recipients of wide FA in every year, except for 2014. The prevalence of wide FA at primary healthcare facilities has been steadily increasing. Conclusion The use of wide FA has been steadily increasing, gradually replacing conventional FA, particularly in primary healthcare settings. Overall, medical expenses continue to rise. The findings of this study provide valuable evidence for the efficient allocation of medical resources in the future.

Objective: This study aimed to compare the efficacy and safety of romosozumab, a bone anabolic agent, versus vertebroplasty, a conventional surgical intervention, in treating osteoporotic vertebral compression fractures (OVCFs). Methods: A retrospective analysis included 86 thoracic/lumbar compression fracture patients from 2014 to 2022 at a medical center. Forty-two patients received romosozumab (monthly injections for 1 year) followed by 1 year of denosumab, while 44 underwent vertebroplasty followed by denosumab injections biannually for 2 years. Outcomes were assessed using the Numerical Rating Scale (NRS) for pain, bone mineral density (BMD), vertebral compression ratio, and Cobb angle over 12 months. Results: At 12 months, the romosozumab group showed a greater reduction in NRS scores (4.90 ± 1.01 vs. 4.27 ± 1.34, p = 0.015) and a higher increase in lumbar BMD (0.8 ± 0.5 vs. 0.5 ± 0.3, p = 0.000) compared to the vertebroplasty group. There were no significant differences in changes in hip total BMD and femur neck BMD (p = 0.190, p = 0.167, respectively). Radiographic assessments showed no significant differences in vertebral compression ratio (14.7% vs. 14.8%; p = 0.960) or Cobb angle (4.2° vs. 4.9°; p = 0.302). The incidence of major osteoporotic fractures was lower in the romosozumab group (7.1% vs. 25.0%, p = 0.051), with similar rates of cardiovascular events in both groups (4.8% vs. 9.1%, p = 0.716). Conclusion Romosozumab has demonstrated superior pain reduction and lumbar BMD improvement compared to vertebroplasty at 12 months, with no significant differences in radiographic outcomes or adverse events, suggesting it as an alternative to vertebroplasty for OVCF.
