		                        			Results:
		                        			The age- and sex-standardized incidence rate of ischemic heart disease (IHD), ischemic stroke, and peripheral artery disease (PAD) decreased from 2010 to 2019 in individuals with type 2 diabetes mellitus (T2DM). However, an increase in the incidence of heart failure (HF) was observed during the same period. Only 4.96% of adults with diabetes and CVD achieved optimal control of all three risk factors (glycemic levels, blood pressure, and lipid control). Additionally, high-intensity statin treatment rates were 8.84% and 9.15% in individuals with IHD and ischemic stroke, respectively. Treatment with a sodium-glucose cotransporter-2 inhibitor (SGLT2i) or a glucagon-like peptide-1 receptor agonist (GLP-1RA) was relatively low in 2019, with only 11.87%, 7.10%, and 11.05% of individuals with IHD, ischemic stroke, and HF, respectively, receiving SGLT2i treatment. Furthermore, only 1.08%, 0.79%, and 1.06% of patients with IHD, ischemic stroke, and HF, respectively, were treated with GLP-1RA. 
		                        		
		                        			Conclusion
		                        			The incidence of most CVD (IHD, ischemic stroke, and PAD) decreased between 2010 and 2019, whereas the incidence of HF increased. The overall use of high-intensity statins, SGLT2i, and GLP-1RA remained low among individuals with T2DM and CVD.

		                        			 A 67-year-old female patient was admitted with posterior neck pain, motor weakness in the right upper extremity, and gait disorder.The patient had a history of Sjogren’s syndrome but no history of rheumatoid arthritis or other specific histories. The finding of cervical myelopathy was confirmed by cervical magnetic resonance imaging. As atlanto-axial instability was observed on the cervical radiography, both posterior fusion and laminectomy were performed. After surgery, the pain decreased and neurological symptoms improved immediately. Thus, in Sjogren’s syndrome, we should pay attention to the presence of atlanto-axial instability in the cervical radiograph.

		                        			 Purpose:
		                        			“Hallux valgus” is a common disease encountered in clinical practice and is accompanied by foot deformities. Conservative treatment is commonly used in the early stages of hallux valgus. On the other hand, surgical treatment often becomes necessary as the deformity progresses. Surgical treatments involve various osteotomy methods or joint fusion procedures combined with soft tissue release, and outcomes from these surgical treatments are generally favorable. This study compared two soft tissue release techniques in the hallux region. 
		                        		
		                        			Materials and Methods:
		                        			This study conducted a retrospective cohort study on 48 participants who underwent surgical treatment for hallux valgus at a single institution from March 1, 2018, to March 31, 2023. A scarf osteotomy was performed in all cases, and the “Modified Mcbride procedure” or “Trans-articular approach” was done for soft tissue release. Hallux valgus angle (HVA), intermetatarsal angle (IMA), and the degree of subluxation of the lateral sesamoid were measured through simple foot radiographs taken before surgery and one year after surgery. 
		                        		
		                        			Results:
		                        			In the Modified Mcbride procedure group, HVA, IMA, and the sesamoid position grade decreased from 34.94º to 9.98º, 15.64º to 5.44º, and 2.47 to 0.44, respectively. In the trans-articular approach group, HVA, IMA, and the sesamoid position grade decreased from 33.42º to 7.34º, 15.06º to 6.03º, and 2.17 to 0.58, respectively. There was no significant difference in these changes between the preoperative and one-year postoperative measurements for both techniques (p-value>0.05). 
		                        		
		                        			Conclusion
		                        			A radiological assessment of soft tissue release through the Modified Mcbride procedure and trans-articular approach in hallux valgus did not show significant differences. Therefore, both surgical techniques can be considered in the distal soft tissue release for a hallux valgus correction. 
		                        		
		                        		
		                        		
		                        	
7.A Case of Cytomegalovirus Retinitis Following Intravitreal Dexamethasone Implant in an Immunocompetent Patient with Uveitis
Journal of the Korean Ophthalmological Society 2019;60(1):85-90
		                        		
		                        			
		                        			PURPOSE: We report a case of cytomegalovirus (CMV) retinitis following placement of an intravitreal dexamethasone implant in an immunocompetent patient diagnosed with non-infectious uveitis. CASE SUMMARY: A 60-year-old woman was referred to our hospital for recurrent anterior uveitis. Fundus examination and fluorescein angiography showed dense vitritis, but no definite retinal infiltration. After laboratory examinations, the patient was diagnosed with non-infectious panuveitis. Uveitis was much improved after the patient started taking oral steroid medication. However, the patient complained of systemic side effects from the oral steroids. Medication was stopped, and an intravitreal dexamethasone implant was fitted to address worsening inflammation. Two months later, perivascular retinal infiltration developed and vitritis recurred. Viral retinitis was suspected, and the patient underwent diagnostic vitrectomy adjunctive with intravitreal ganciclovir injection. Polymerase chain reaction of vitreous fluid confirmed the diagnosis of CMV retinitis. The patient has remained inflammation-free for more than 20 months after vitrectomy, single ganciclovir injection, and 2 months of oral valganciclovir medication. CONCLUSIONS: This is a case report of CMV retinitis following placement of an intravitreal dexamethasone implant in an immunocompetent patient without any risk factors or previous history of immunosuppression. Potential risk factors for CMV retinitis should be evaluated and careful follow-up should be performed when intravitreal dexamethasone injections are unavoidable for the treatment of non-infectious uveitis.

8.Homonymous Quadrantanopia Caused by Occipital Lobe Ulegyria
Journal of the Korean Ophthalmological Society 2019;60(2):201-204
		                        		
		                        			
		                        			PURPOSE: We report a case of homonymous quadrantanopia caused by occipital lobe ulegyria. CASE SUMMARY: A 23-year-female was referred to our clinic because of a visual field defect incidentally discovered during preoperative evaluation for refractive surgery at another clinic. However, she did not report any symptoms. She had no systemic diseases. Visual acuity was 20/20 in both eyes, and the color vision test was normal. Both pupils exhibited normal responses to light and near stimulations. In fundus examinations, the right optic disc was normal and the left contained drusen. Automated perimetry revealed right lower homonymous quadrantanopia with macular sparing. Brain magnetic resonance imaging revealed areas of ulegyria involving the left occipital lobe, consistent with the visual field defect. A follow-up visual field test performed 5 months later yielded the same result. CONCLUSIONS: Neuroimaging should be performed in patients with homonymous visual field defects to determine the location and etiology of the brain lesions. Occipital lobe ulegyria can cause homonymous quadrantanopia in the absence of any neurological problem.

		                        			PURPOSE: To determine whether early visual acuity response to intravitreal bevacizumab in macular edema (ME) secondary to branch retinal vein occlusion (BRVO) is associated with 12-month follow-up outcome. METHODS: Sixty treatment-naïve patients (60 eyes) with ME secondary to BRVO treated with intravitreal bevacizumab (1.25 mg) were retrospectively included. Initially, all patients were injected monthly to achieve fluid resolution and followed up with a pro re nata regimen for at least 12 months. The relationship between early (month 1) and late (month 12) visual acuity response (mean change from baseline in best-corrected visual acuity [BCVA]; categorized improvement [<1, 1–3, or ≥3 logMAR lines in BCVA]) was explored. RESULTS: The proportions of eyes with <1, 1-<3, and ≥3-line improvements at 1 month were 19 eyes (31.7%), 17 eyes (28.3%), and 24 eyes (40%), respectively. Within each of the three response categories, the mean BCVA change from baseline at 12 months and onward did not vary by more than 1 line from the observed mean BCVA improvement at 1 month. Inter-cohort differences across the three response categories in mean BCVA change from baseline were statistically significant at each time point. Early BCVA response at 1 month showed significant associations with ≥3 line improvement and BCVA response at 12 months in multiple logistic and linear regression analyses. CONCLUSIONS: Early BCVA responses to bevacizumab are associated with subsequent responses over the entire 12-month duration of treatment.

		                        			PURPOSE: To compare the short-term efficacy of intravitreal aflibercept and ranibizumab treatment according to the subtypes of polypoidal choroidal vasculopathy (PCV) based on indocyanine green angiography (ICGA). METHODS: Fifty-five treatment naïve patients with PCV who underwent intravitreal anti-vascular endothelial growth factor (VEGF) (ranibizumab, 26 eyes; aflibercept, 29 eyes) injection were retrospectively analyzed. Based on ICGA, subjects with feeder and draining vessels were defined as type 1 PCV (33 eyes), and subjects who did not have either feeder or draining vessels, but had branch vascular networks were defined as type 2 PCV (22 eyes). The complete polyp regression was assessed at 3 months after the initial treatment using ICGA. Changes in best-corrected visual acuity (BCVA) and optical coherence tomographic parameters were evaluated at 3 and 6 months. RESULTS: Patients with type 1 PCV showed a higher complete polyp regression percentage (p = 0.034) and better visual improvement (p = 0.017) after three monthly injections compared to patients with Type 2 PCV. At 3 and 6 months, the BCVA was significantly improved in type 1 PCV patients, but not in type 2 PCV patients. In patients with type 1 PCV, the aflibercept-treated group showed a better response in anatomical outcomes (p = 0.020), and complete polyp regression percentage (p = 0.027; dry macula) than the ranibizumab-treated group, and only the aflibercept-treated group showed a significant improvement of BCVA at 3 and 6 months. In patients with type 2 PCV, there were no significant differences in visual and anatomical outcome between the anti-VEGF agents. CONCLUSIONS: Type 1 PCV showed better visual improvement with a higher percentage of polyp regression than type 2 PCV. Anatomical changes were greater in patients treated with aflibercept than with ranibizumab, particularly in patients with type 1 PCV. These results suggest that a consideration of angiographic features is important in establishing a treatment strategy for patients with PCV.
