ABSTRACT
Purpose@#To compare the intraocular pressure reduction and changes in ocular pulse amplitude of travoprost 0.003% and tafluprost 0.0015%. @*Methods@#We assessed patients who were diagnosed with open-angle glaucoma from January 2017 to July 2019 for the first time at our hospital. Forty-two eyes were assigned to the travoprost group (23 patients) and 26 eyes were assigned to the tafluprost group (14 patients). Changes in intraocular pressure were measured by Goldmann applanation tonometry (GAT), and corrected ocular pulse amplitude (cOPA) was measured using dynamic contour tonometry. Changes in these parameters were observed and compared for 1 year. @*Results@#No significant differences were observed between the GAT measurements and the cOPA of patients treated with travoprost and tafluprost for 1 year (p = 0.512, p = 0.105). The change in initial intraocular pressure on GAT observed after 1 week was -5.32 ± 2.63 mmHg for travoprost and -3.79 ± 3.19 mmHg for tafluprost (p = 0.0457). The initial change in cOPA was +0.04 ± 0.9 mmHg in the travoprost group and -0.76 ± 0.97 mmHg in the tafluprost group (p = 0.0028). @*Conclusions@#Travoprost and tafluprost reached the targeted intraocular pressure with no difference in the long-term effects of reduced intraocular pressure. However, travoprost was initially better at lowering intraocular pressure faster, and tafluprost had a greater effect on lowering OPA. Prostaglandin analogs can be selected individually by considering the aforementioned factors.
ABSTRACT
Background@#In Korea, the health gap widens due to the number of medical resources and access to medical services between metropolitan and rural. The purpose of this study is to identify the impact of residential migration on medical utilization and accessibility. @*Methods@#This study extracted 528,516 claimed cases in the National Health Insurance Service-Cohort Sample Database from 2006 to 2015. Subjects were classified into two groups by the magnitude of the region, the metropolitan and the rural. The inversed probability weights were calculated for each group. And coefficients of the two-part model were estimated by generalized estimation equation. @*Results@#Those who moved region from metropolitan to rural tend to increase the length of stay and inpatients with ambulatory care sensitive conditions (ACSC) disease. Contrariwise, those who moved areas from rural to metropolitan tend to decrease the total medical cost, the adjusted patient days, the number of outpatients and the number of outpatients and inpatients with ACSC disease. @*Conclusion@#This study identified that between the residents who continued to reside in the region and the migrants, there were significant differences in the medical accessibility, quality of primary care, and unmet medical need.

ABSTRACT
PURPOSE: To report a case of optic neuritis accompanied by optic perineuritis after retinalamin peribulbar injection. CASE SUMMARY: A 46-year-old Kazakhstan woman presented with sudden vision loss, headache, and pain in both eyes which began 2 hours after the peribulbar injection of retinalamin approximately 10 days prior to her initial visit. At the initial visit, the best-corrected visual acuity was light perception in both eyes. A fundus examination showed bilateral optic disc swelling and fluorescein angiography showed late-phase leakage around the optic nerve and optic nerve sheath enhancement. On brain magnetic resonance imaging, the tram track sign and donut sign were seen in both eyes. Steroid pulse therapy was started after the diagnosis of optic neuritis accompanied by optic perineuritis. After 6 months, the patient's visual acuity improved up to 0.8 in the right eye and 1.0 in the left eye. The light reflex was recovered, the relative afferent pupillary defect decreased, and there was no evidence of optic disc swelling. CONCLUSIONS: When an unverified drug injection is performed (e.g., retinalamin), it could result in complications such as optic neuritis and optic perineuritis from an allergic reaction or peribulbar injection trauma. In such cases, high-dose steroid pulse therapy may be considered.
