Background To investigate the relationship between blepharitis and metabolic syndrome (MetS) by using the Longitudinal Health Insurance Database (LHID) of Taiwan. Methods This retrospective cohort study was conducted using data collected from the LHID for the period from 2009 to 2013. This study enrolled patients who received a diagnosis of blepharitis according to the International Classification of Diseases, Ninth Revision, diagnostic code. The exclusion criteria were legal blindness, eyeball removal, ocular tumours prior to the diagnosis of blepharitis, and patients diagnosed with blepharitis and initiated antibiotic treatment concurrently. An age-matched, gender-matched and disease-matched population without blepharitis served as the control group. Multivariate analysis with a multiple Cox regression model was applied to analyse the data. Results In this study, a total of 10 093 patients with blepharitis were included in the study group, and another 40 372 participants without blepharitis were included in the control group. Conditional logistic regression revealed a higher cumulative probability of hyperlipidaemia and coronary arterial disease. After adjustment, patients with blepharitis had a higher probability of developing new MetS than controls. According to subgroup analysis, hyperlipidaemia and coronary artery diseases were significantly correlated with the prior development of blepharitis. However, hypertension and diabetes mellitus and insulin resistance showed no correlation with blepharitis. Conclusion Blepharitis is significantly related to MetS and can serve as an early sign of MetS. Additional studies should examine the relationship between blepharitis and MetS in terms of severity.

To evaluate the safety and efficiency in macular edema patients who concurrently received a single injection of a dexamethasone intravitreal implant (DEX, 0.7mg) and ranibizumab (2.3 mg). A retrospective cohort study was conducted, and medical records from 2012 to 2016 were reviewed. Patients who received concurrent DEX and ranibizumab injections with a follow-up period of at least 3 months were enrolled in the study group. An age and gender-matched group received ranibizumab injections and was designated the control group. The best-corrected visual acuity (BCVA), central macular thickness (CMT) and intraocular pressure (IOP) were included in the analysis. Steroid-induced ocular hypertension (SIOH) is defined as either an elevation of more than 10 mmHg from baseline or a single IOP measurement of more than 30 mmHg. A total of 26 patients were enrolled in the current study with 13 patients in each group. Both the BCVA (P=.04) and CMT (P<.01) achieved significant improvement after the follow-up period in the study group. The IOP increased after the injection but no significant elevation was observed throughout the follow-up period in the study group (P=.15). For SIOH, 1 patient in the study group had an elevated IOP of 10 mmHg (7.7%) at 2 postoperative months, and no single IOP measurement of more than 30 mmHg was obtained. Five patients (38.5%) in the study group received medical treatment that successfully retarded their IOP elevation, and no individuals required surgical management. In the control group, there were no significant fluctuations concerning BCVA, CMT, and IOP, and no ocular hypertension was observed. According to the inter-group analysis, the CMT and BCVA recovered more significantly in the study group than in the control group. Concurrent injection of DEX and ranibizumab is a preliminary method that shows effectiveness in treating ME. Furthermore, safety is also guaranteed, with moderate levels of severity and transient IOP elevation being observed. A future large-scale study is necessary to evaluate the long-term effects and safety of this combined treatment.

PURPOSE. The purpose of this study was to evaluate the effect of uveitis on the development of various keratopathies via the use of the National Health Insurance Research Database (NHIRD) in Taiwan. METHODS. Approximately 1 million patients were randomly sampled from the registry of the NHIRD. Patients diagnosed with uveitis by ophthalmologists were enrolled in the study group after exclusion. Each individual in the study group was age and sex matched to four nonuveitis individuals who serve as the control group. In addition to keratopathy, other possible risk factors and medications were included in the multivariate model, and the effects of different subtypes of uveitis for developing keratopathies were also analyzed. RESULTS. A total of 4773 uveitis patients (2662 male and 2111 female) and 19,092 non-uveitis patients (10,648 male and 8444 female) were enrolled. There were 406 events of keratopathy in the study group, and another 764 events occurred in the control group. A higher incidence rate was found in the study group after adjustment (adjusted hazard ratio [aHR]: 1.772), with a greater cumulative probability (P < 0.0001). For the subgroup analysis, anterior uveitis (aHR = 1.765) and panuveitis (aHR = 3.386) increased the risk of developing keratopathies. Moreover, male sex was associated with a higher aHR than female sex for developing keratopathies in the study group. CONCLUSIONS. The presence of uveitis significantly elevates the risk for developing keratopathy.

The aim of the present study was to survey the relationship between central serous chorioretinopathy (CSC) and several cardiovascular diseases (CVDs) with different severities using the National Health Insurance Research Database. A retrospective cohort study was conducted. Subjects with CSC were enrolled according to the relevant diagnostic codes, and an age- and gender-matched population was used as the control group with a 1:4 ratio. The main outcome being considered was the development of CVD after CSC exposure. Cox proportional hazard regression was applied to calculate the adjusted hazard ratio (aHR) of CSC and CVD of different types. A total of 2865 patients that were diagnosed with CSC were enrolled in the study group, while another 11,460 non-CSC subjects were selected as the control group. There were 171 events of CVD which occurred in the study group, while another 557 cases were found in the control group. No significant differences were observed among the CVD cases between the study and control group, whether they had an acute or chronic form, according to the aHR. In the subgroup analysis, there was a significantly higher risk of CVD development in the male population aged from 40 to 59 years (aHR: 1.351, confidence interval (CI): 1.063-1.716), which was mainly due to the higher risk of mild CVD (aHR: 1.391, CI: 1.062-1.822). On the contrary, there was no significant difference in CVD development in any of the age subgroups of the female population. In conclusion, the existence of CSC is correlated with a higher rate of chronic CVD occurrence in the middle-aged male population.
