Association of sodium-glucose cotransporter-2 inhibitors and the risk of retinal vascular occlusion: A real-world retrospective cohort study in Taiwan.

AIMS: Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are proposed to alleviate the development of inflammatory eye diseases. However, the association between SGLT2i and retinal vascular occlusion remains unclear. Therefore, this study aims to explore the effects of SGLT2i on the incidence of retinal vascular occlusion. MATERIALS AND METHODS: This retrospective cohort study analysed electronic medical records data from the largest multi-institutional database in Taiwan. Individuals who initiated SGLT2is and dipeptidyl peptidase 4 inhibitors (DPP4is) between 2016 and 2019 were included in our analysis. To conduct a homogenous comparison, inverse probability of treatment weighting with propensity scoring was employed. The primary outcome was retinal vascular occlusion, and the secondary outcomes were retinal vascular occlusion-related complications (macular oedema, vitreous haemorrhage, and tractional retinal detachment) and conditions requiring vitreoretinal intervention (intravitreal injection, retinal laser therapy, and vitrectomy). RESULTS: In total, 12,074 SGLT2i users and 39,318 DPP4i users were included. The incidence rate of retinal vascular occlusion in the SGLT2i and DPP4i groups was 1.2 (95% confidence interval [CI], 0.9-1.4) and 1.6 (95% CI, 1.3-1.8) events per 1000 person-years, respectively, which yielded a subdistribution hazard ratio (SHR) of 0.74 (95% CI, 0.55-0.99). Similar risk reductions were observed in the retinal vascular occlusion-related complications (SHR, 0.76; 95% CI, 0.69-0.84) and conditions requiring vitreoretinal intervention (SHR, 0.84; 95% CI, 0.77-0.94). CONCLUSIONS: In this multi-institutional study in Taiwan, SGLT2i use was associated with a reduced risk of retinal vascular occlusion. Further prospective studies are required to ascertain this association.

Noncontact optical device for measuring blood glucose in aqueous humor: a pilot clinical study investigating correlation with blood glucose levels.

Significance: Monitoring blood glucose levels is crucial for individuals with diabetes. Noninvasive methods for measuring serum glucose levels have been explored to aid in blood glucose control for diabetes management. Aim: We introduced a noncontact optical glucometer (NCGM) for measuring glucose levels in the aqueous humor of the human eye. We also investigated the correlation between glucose levels in the NCGM and the aqueous humor, blood samples, and self-monitoring blood glucose devices. Approach: The optical system used in this study measured both the near-infrared absorption and polarized rotatory distribution of glucose molecules in the human aqueous humor. This prospective study's outcomes were eye aqueous glucose level, preoperative blood glucose level, intraoperative blood glucose level, and NCGM reading of patients in a single center in Taiwan. Results: The NCGM's measurements showed a strong correlation with blood glucose levels (intra-class correlation [ICC]: 0.95 to 0.98) and aqueous humor glucose levels (ICC: 0.76), indicating its ability to noninvasively measure blood glucose levels in human subjects. Conclusions: This NCGM may offer a convenient, pain-free, and rapid tool for measuring blood glucose levels in diabetic patients. The device could represent a significant advancement in noncontact hybrid optical glucose measurement systems.

Trocar blade-assisted skewer technique for phacoemulsification of a dislocated lens.

A posteriorly dislocated lens is often managed with a fragmatome through a pars plana approach because it is difficult to manage anteriorly. The lens often sinks to the surface of the retina or floats around in the vitreous cavity during pars plana lensectomy. Mechanical trauma can occur while removing the dislocated lens fragments. However, sometimes the lens can be confined to the anterior vitreous cavity even though the zonules are completely disrupted. It would be ideal if there was a simple way to stabilize and support the lens so that the lens could remain in the posterior chamber while phacoemulsification is performed through a corneal incision as usual. We describe a technique using a trocar blade to stabilize the lens while performing phacoemulsification through a corneal incision. We found it to be a useful and safe instrument to support the subluxated lens during phacoemulsification.

A comparative study of stereopsis in term and preterm children with and without retinopathy of prematurity.

PURPOSE: To evaluate stereopsis in term-born, preterm, and preterm children with and without retinopathy of prematurity (ROP) and its treatment. METHODS: The cross-sectional study included 322 children between 3 and 11 years of age born term or preterm, with or without ROP, and with or without treatment for ROP. The ROP treatments were laser therapy, intravitreal injection (IVI) of anti-vascular endothelial growth factor, or their combination. Stereoacuity was measured using the Titmus Stereo Test, and the results among various age groups were analyzed. RESULTS: Stereopsis was found to improve with increasing age at testing (P < 0.001) across the entire study population. The term group exhibited significantly better stereoacuity than the preterm group (P < 0.001). At 3-5 years and 6-8 years, the preterm children without ROP exhibited significantly better stereoacuity than did those with ROP (P < 0.001 and P = 0.02, respectively); however, at 9-11 years, both groups exhibited similar stereoacuity (P = 0.34). The stereoacuity in the children with untreated ROP was similar to that of the children with treated ROP in all age groups (P > 0.05). No significant differences in stereopsis were identified between children with ROP treated with laser versus with IVI (P > 0.05). From multivariate analysis, younger age at testing (P = 0.001) and younger gestational age (P < 0.001) were associated with poorer stereopsis. CONCLUSIONS: Stereopsis development gradually improved with age in all groups. The children born preterm exhibited poorer stereoacuity than those born term. Children with ROP treated with laser photocoagulation versus IVI may exhibit similar levels of stereoacuity. Younger age at testing and gestational age were independent risk factors for poorer stereoacuity.

Longitudinal Changes in Choroidal Thickness in Children with a History of Prematurity: An 18-month Prospective Cohort Study.

PURPOSE: To evaluate choroidal changes over time in school-aged children with a history of prematurity. METHODS: A study of 416 eyes, including 88, 190, 36, 56, and 46 eyes in the full-term control, preterm, spontaneously regressed retinopathy of prematurity (ROP), intravitreal bevacizumab (IVB)-treated ROP, and laser-treated ROP groups, respectively. The choroidal thickness was measured 4 times at 6-month intervals by optical coherence tomography. RESULTS: Of all the groups, the laser-treated children had the thinnest choroid compared with full-term children (-52.3 µm, P = .04). Preterm children exhibited greater attenuation in choroidal thickness over time than did full-term children (-6.3 ± 26.9 and -1.1 ± 12.8 µm/year, P = .03), whereas no difference was observed between IVB and laser treatments (-4.6 ± 18.9 and -2.0 ± 15.7 µm/year, P = .46). In all groups, the changes in axial length were negatively associated with the changes in choroidal thickness (all P < .05). CONCLUSION: A greater attenuation in choroid thickness over time was observed in preterm children than in full-term children, but this attenuation did not differ between IVB and laser treatments. Axial elongation was associated with choroidal thinning in school-aged children.

Taiwan ocular inflammation society consensus recommendations for the management of juvenile idiopathic arthritis-associated uveitis.

We presented the development of a consensus guideline for managing juvenile idiopathic arthritis-associated uveitis (JIAU) in Taiwan, considering regional differences in manifestation and epidemiology. The Taiwan Ocular Inflammation Society (TOIS) committee formulated this guideline using a modified Delphi approach with two panel meetings. Recommendations were based on a comprehensive evidence-based literature review and expert clinical experiences, and were graded according to the Oxford Centre for Evidence-Based Medicine's "Levels of Evidence" guideline (March 2009). The TOIS consensus guideline consists of 10 recommendations in four categories: screening and diagnosis, treatment, complications, and monitoring, covering a total of 27 items. These recommendations received over 75% agreement from the panelists. Early diagnosis and a coordinated referral system between ophthalmologists and pediatric rheumatologists are crucial to prevent irreversible visual impairment in children with JIAU. However, achieving a balance between disease activity and medication use remains a key challenge in JIAU management, necessitating further clinical studies.

Exploring the Location of Corneal Pigmented Arc and Myopia Control Efficacy in Orthokeratology-Treated Children Using Pentacam Measurements.

OBJECTIVES: To determine the location and intensity of the corneal pigmented arc in orthokeratology (ortho-k)-treated children and its relationship with annual axial length (AL) change using Pentacam. METHODS: This retrospective cohort study enrolled children aged 9 to 15 years who had been followed up for at least one year after ortho-k treatment for myopia control. A Pentacam was used to determine the location and intensity of pigmented arc after lens wear. Annual AL changes were further used as the outcome measurement to determine their relationships with the location and intensity of pigmented arc using generalized estimating equations (GEE). RESULTS: In total, 62 eyes from 33 patients (mean age 10.9 years) were included in our final analysis. The mean follow-up time was 30.6 months. The mean annual AL changes were 0.10 mm. Age statistically correlated with annual AL change (GEE, P= 0.033). In addition, the annual AL change was negatively associated with the relative vertical distance of the lowest density of pigmented arc point based on the visual center, pupil center, and corneal thinnest point after adjustment with age ( P =0.005, P =0.004, and P< 0.001, respectively). CONCLUSIONS: Pentacam could be a useful tool for evaluating the location and intensity of the corneal pigmented arc. In addition, there was a negative correlation between the vertical distance of the pigmented arc and annual AL change. These findings may provide important information regarding myopia control, next-generation ortho-k design, and prescription.

PRESENTATIONS AND FACTORS AFFECTING OUTCOME OF RHEGMATOGENOUS RETINAL DETACHMENT WITH CHOROIDAL DETACHMENT: An Indo-Taiwanese Study.

PURPOSE: To report the clinical settings, management, and factors associated with outcomes of rhegmatogenous retinal detachment with concurrent choroidal detachment. METHODS: Retrospective, consecutive, multicenter case series from January 2014 to January 2021 were included. Cases were from a tertiary eye care center in India and Taiwan. RESULTS: Overall 303 eyes were included. Mean age was 43.72 ± 20.64 years (median 46). Best-corrected presenting visual acuity was 1.79 ± 0.92 logMAR (median 2.10) (Snellen 20/1,233). Forty-four patients (17.91%) received preoperative steroids. Final visual acuity was 1.33 ± 0.94 logMAR (median 1.10) (Snellen 20/427). Favorable anatomic outcome was seen in 200/303 (66%), whereas favorable functional outcome was seen in 128/303 (42.20%). Factors predicting favorable anatomic outcome were absence of phakic lens status (odds ratio [OR] 2.76), absence of proliferative vitreoretinopathy worse than Grade A (OR 7.69), use of preoperative steroids (OR 4.50), and use of an encircling band (3.85). Factors predicting favorable functional outcome were better presenting visual acuity (OR 3.03), absence of phakic lens status (OR 4.93), absence of proliferative vitreoretinopathy worse than Grade A (OR 10.41), and use of preoperative steroids (OR 7.24). CONCLUSION: Administration of preoperative steroids, use of an encircling band during surgery, and pseudophakic status of the eye were found to have better outcomes in rhegmatogenous retinal detachment with concurrent choroidal detachment.

Diagnosis, Treatment, and Prevention of Noninfectious Acute Anterior Uveitis with or without Human Leukocyte Antigen B27 in Adults - Expert Consensus in Taiwan.

BACKGROUND: Anterior uveitis is the most common anatomical type of uveitis. Patients with noninfectious anterior uveitis may develop various ocular complications and eventually visual impairment. Appropriately differentiating the etiologies can help clinicians to predict the outcome, arrange clinical follow-up, and decide the treatment or prevention strategy. Adequate treatment and effective prevention strategies can reduce the frequency of recurrence and the risk of developing complications. Human leukocyte antigen (HLA)-B27 is the most common positive finding in patients with noninfectious AAU in many countries including Taiwan. PURPOSE: To report a consensus from experienced uveitis specialists and rheumatologists was made in Taiwan. METHODS: A panel of nine ophthalmologists from nine different referral centers with expertise in the management of uveitis and an experienced rheumatologist was held on January 16, 2022. A comprehensive literature review was performed. Differential diagnoses for etiologies, general treatments, and prevention strategies were discussed. Each statement in the consensus was made only if more than 70% of the experts agreed. RESULTS: A flow chart and seven statements regarding the differential diagnoses for etiologies, treatments and preventions, and co-management with rheumatologists were included in the consensus. CONCLUSIONS: This article discusses the general diagnosis, treatment, and prevention of noninfectious acute anterior uveitis, with or without HLA-B27, in adults for general ophthalmologists to improve overall outcomes of these patients.

Association of SDF-1 and its receptor CXCR4 polymorphisms on the susceptibility of diabetic retinopathy in the Taiwanese population.

Stromal cell-derived factor-1 (SDF-1) and its receptor CXC chemokine 4 (CXCR4) have been demonstrated to play critical roles in diabetic retinopathy (DR). This study investigated whether single-nucleotide polymorphisms (SNPs) of SDF-1 and its receptor CXCR4 are correlated with diabetic retinopathy (DR). Three SDF-1 SNPs, namely, rs1801157 (G/A), rs2297630 (G/A), and rs266085 (T/C), and two CXCR4 SNPs, namely, rs2228014 (C/T) and rs6430612 (C/T), were chosen and genotyped via the TaqMan allelic discrimination for 454 non-DR subjects and 276 DR individuals. Our results revealed that subjects carrying SDF-1 SNP rs2297630 GA (AOR: 2.962, 95% CI: 1.279-6.861, p = 0.011) and SDF-1 SNP rs2297630 GA + AA (AOR: 3.095, 95% CI: 1.394-6.872, p = 0.006) had significantly higher risk in the non-proliferative diabetic retinopathy (NPDR) groups than in the non-DR group. Further analyses using the datasets from the Genotype-Tissue Expression (GTEx) Portal revealed that SDF-1 SNP rs2297630 GA and AA genotypic variants have higher SDF-1 expression than the GG wild-type alleles (p = 0.000016). In conclusion, our findings revealed that SDF-1 SNP rs2297630 was associated with NPDR.

MicroRNA-152-3p and MicroRNA-196a-5p Are Downregulated When Müller Cells Are Promoted by Components of the Internal Limiting Membrane: Implications for Macular Hole Healing.

Müller cells play a critical role in the closure of macular holes, and their proliferation and migration are facilitated by the internal limiting membrane (ILM). Despite the importance of this process, the underlying molecular mechanism remains underexplored. This study investigated the effects of ILM components on the microRNA (miRNA) profile of Müller cells. Rat Müller cells (rMC-1) were cultured with a culture insert and varying concentrations of ILM component coatings, namely, collagen IV, laminin, and fibronectin, and cell migration was assessed by measuring cell-free areas in successive photographs following insert removal. MiRNAs were then extracted from these cells and analyzed. Mimics and inhibitors of miRNA candidates were transfected into Müller cells, and a cell migration assay and additional cell viability assays were performed. The results revealed that the ILM components promoted Müller cell migration (p < 0.01). Among the miRNA candidates, miR-194-3p was upregulated, whereas miR-125b-1-3p, miR-132-3p, miR-146b-5p, miR-152-3p, miR-196a-5p, miR-542-5p, miR-871-3p, miR-1839-5p, and miR-3573-3p were significantly downregulated (p < 0.05; fold change > 1.5). Moreover, miR-152-3p and miR-196a-5p reduced cell migration (p < 0.05) and proliferation (p < 0.001), and their suppressive effects were reversed by their respective inhibitors. In conclusion, miRNAs were regulated in ILM component-activated Müller cells, with miR-152-3p and miR-196a-5p regulating Müller cell migration and proliferation. These results serve as a basis for understanding the molecular healing process of macular holes and identifying potential new target genes in future research.

Clinical Characteristics and Genetic Variants in Taiwanese Patients With PROM1-Related Inherited Retinal Disorders.

Purpose: This study investigated the clinical characteristics of patients with PROM1-related inherited retinal diseases (IRDs). Methods: Patients diagnosed with IRDs who had mutations in PROM1 were identified at Linkou Chang Gung Memorial Hospital and Kaohsiung Medical University Hospital in Taiwan. Information on clinical characteristics and best-corrected visual acuity was recorded. Color fundus (CF) images, fundus autofluorescence photography (FAF), spectral-domain optical coherence tomography (SD-OCT), and electroretinograms (ERGs) were analyzed to examine patient phenotypes. PROM1 variants were detected using whole exome sequencing and verified by Sanger sequencing. Results: Fourteen patients from nine families with PROM1-related IRDs were analyzed. Most patients exhibited chorioretinal atrophy in the macular area, with or without extramacular involvement on CF. Similarly, hypo-autofluorescence confined to the macular area, with or without extramacular involvement, was present for most patients on FAF. Furthermore, SD-OCT revealed outer retinal tubulations and focal or diffuse retinal thinning. ERGs showed variable findings, including maculopathy with normal ERG, subnormal cone response, and extinguished rod and cone responses. We detected five variants of the PROM1 gene, including c.139del, c.794del, c.1238T>A, c.2110C>T, and c.1117C>T. Conclusions: In this study, we evaluated 14 Taiwanese patients with five PROM1 variants. Additionally, incomplete penetrance of heterozygous PROM1 variants was observed. Furthermore, patients with autosomal dominant PROM1 variants had lesions in the macular area and the peripheral region of the retina. SD-OCT serves as a useful tool for early detection of PROM1-related IRDs, as it captures certain signs of such diseases.

Retinal vascular arcade angle as a biomarker for visual improvement after epiretinal membrane surgery.

OBJECTIVES: To investigate the changes in the temporal vascular angles after epiretinal membrane (ERM) surgery and utilize the angles to predict visual outcomes. METHODS: A total of 168 eyes from 84 patients with unilateral ERM who underwent vitrectomy were enrolled from a single institution. The angles of temporal venous (anglevein) and arterial arcades (angleartery) were measured on fundus photographs. The relationships between the angles and the best-corrected visual acuity (BCVA) were explored and multivariable logistic models and receiver operating characteristic (ROC) curves were analyzed to identify the factors that predicted visual outcomes. RESULTS: At baseline, both angleartery and anglevein were narrower in the eyes with ERM than the fellow eyes (p < 0.001 and 0.007) but had no correlation with the baseline BCVA (p = 0.754 and 0.804). Postoperatively, the angleartery and anglevein significantly widened (both p < 0.001) and a greater BCVA improvement was associated with a greater widening of the angleartery (p = 0.029) and anglevein (p = 0.050). Multivariable logistic analyses found a narrower baseline angleartery compared to the fellow eye had a higher chance for BCVA improvement ≧ 2 lines (Odds ratio = 0.97; 95% CI, 0.94-0.99; p = 0.016). ROC curve showed the baseline difference in the angleartery between bilateral eyes predicted BCVA improvement ≧ 2 lines (area under the curve = 0.74; p = 0.035), and a 0.73 sensitivity and 0.80 specificity with a cut-off value of -27.19 degrees. CONCLUSIONS: The retinal vascular angles widened after ERM surgery and the fundus photograph-derived angles may serve as a highly-accessible biomarker to predict postoperative visual outcomes.

Treatment of Myopia with Atropine 0.125% Once Every Night Compared with Atropine 0.125% Every Other Night: A Pilot Study.

(1) Purpose: To investigate the efficacy of myopia treatment in children using atropine 0.125% once every two nights (QON) compared with atropine 0.125% once every night (HS). (2) Methods: This retrospective cohort study reviewed the medical records of two groups of children with myopia. Group 1 comprised children treated with atropine 0.125% QON, while group 2 included children treated with atropine 0.125% HS. The first 6 months of data of outcome measurements were subtracted as washout periods in those children undergoing both atropine QON and HS treatment. The independent t-test and Pearson's chi-square test were used to compare the baseline clinical characteristics between the two groups. A generalized estimating equations (GEE) model was used to determine the factors that influence treatment effects. (3) Results: The average baseline ages of group 1 (38 eyes from 19 patients) and group 2 (130 eyes from 65 patients) were 10.6 and 10.2 years, respectively. There were no significant differences in axial length (AL) or cycloplegic spherical equivalent (SEq) at baseline or changes of them after 16.9 months of follow-up. GEE showed that the frequency of atropine 0.125% use has no association with annual AL (QON vs. HS: 0.16 ± 0.10 vs. 0.18 ± 0.12) and SEq (QON vs. HS: -0.29 ± 0.44 vs. -0.34 ± 0.36) changes in all children with myopia. It also showed that older baseline age (B = -0.020, p < 0.001) was associated with lesser AL elongation. (4) Conclusion: The treatment effects of atropine 0.125% HS and QON were similar in this pilot study. The use of atropine 0.125% QON may be an alternative strategy for children who cannot tolerate the side effects of atropine 0.125% HS. This observation should be confirmed with further large-scale studies.

Analysis of Retinol Binding Protein 4 and ABCA4 Gene Variation in Non-Neovascular Age-Related Macular Degeneration.

Age-related macular degeneration (AMD) may be associated with ABCA4 variants and is characterized by the accumulation of visual cycle-byproduct lipofuscin. Reducing retinol-binding protein 4 (RBP4), a retinol transporter protein, may reduce lipofuscin production. This study aims to assess the associations between plasma RBP4, the ABCA4 variation, and AMD severity. Sixty-seven participants were grouped into healthy/mild AMD (n = 32) and severe AMD (n = 35) groups. The latter group was older than the former group and had higher levels of RBP4 (36.8 ± 8.3 vs. 30.4 ± 7.0 µg/mL, p = 0.0012). The ten participants with six ABCA4 linked-variants had higher RBP4 than those without (37.8 ± 7.7 vs. 32.4 ± 7.9 µg/mL; p = 0.026), and eight of them had severe AMD. Univariate analyses showed that severe AMD was related to older age (OR, 1.26; 95% CI, 1.13-1.40; p < 0.0001) and to higher RBP4 levels (OR, 1.12; 95% CI, 1.04-1.20; p = 0.003), whereas the linked ABCA4 variants had no associations. After adjustment, however, only age remained significantly associated with severe AMD. This pilot study shows a trend of higher plasma RBP4 levels in severe AMD or the ABCA4-linked variants, and further age-matched studies are warranted.

Respiratory outcomes in preterm infants following intravitreal bevacizumab for retinopathy of prematurity-a 10-year matched case study.

OBJECTIVES: To evaluate respiratory outcomes in preterm infants with retinopathy of prematurity (ROP) following intravitreal bevacizumab injection (IVB). METHODS: This single-centre study enroled preterm infants with a gestational age (GA) < 34 weeks or a birth weight (BW) < 1500 g with bilateral type 1 ROP who received a single IVB, and a treatment-free control group matched by GA, postmenstrual age, and respiratory status at the time of the IVB. The primary outcome was serial respiratory changes in mean airway pressure (MAP), fraction of inspired oxygen (FiO2), and respiratory severity score (RSS, MAP x FiO2) during the 28-day post-IVB/matching period and overall respiratory improvement at day 28 and at discharge. The duration of supplemental oxygen therapy following IVB/matching was documented. RESULTS: A total of 5578 infants were included. Seventy-eight infants were enroled in the IVB group, and another 78 infants were matched as the control group. Both groups had downward trends in the MAP, FiO2, and RSS over the study period (all P < 0.001), but there were no between-group differences in these measures. The percentage of overall respiratory improvement was similar between the IVB and control groups, so was the duration of invasive and in-hospital oxygen ventilation. A lower percentage of oxygen dependence at discharge in the IVB group (P = 0.03) remained significant after adjusting for GA and BW. CONCLUSIONS: This is a matched case study to evaluate respiratory outcomes in preterm infants following IVB for ROP. We found that the IVBs did not compromise respiratory outcomes in preterm infants during the 28-day post-IVB period and at discharge.

Associations of VEGF Polymorphisms With Retinopathy of Prematurity.

Purpose: This study investigated the associations between vascular endothelial growth factor (VEGF) polymorphisms and retinopathy of prematurity (ROP) risk. Methods: Infants born prematurely at any time from 2009 to 2018 were included. Five single-nucleotide polymorphisms (SNPs) of VEGF were analyzed using real-time PCR in all infants. Multivariate logistic regression was applied to model the associations between VEGF polymorphisms and ROP susceptibility, severity, and premature clinicopathologic characteristics. Results: A total of 334 patients were included and categorized into three groups: those without ROP, those with mild ROP (i.e., ROP not requiring treatment), and those with severe ROP (i.e., ROP for whom treatment was indicated). Among the female patients with ROP, those with VEGF rs3025035 CT (3.231-fold; 95% confidence interval [CI], 1.238-8.431) and a combination of CT and TT genotypes (2.643-fold; 95% CI, 1.056-6.619) exhibited significantly higher risks of severe ROP compared with those with wild-type genotypes. Female ROP infants with VEGF rs3025010 C (TC + CC) alleles had a lower risk of ROP stage ≥3 (odds ratio [OR] = 0.406; 95% CI, 0.165-0.999) than those with TT homozygotes. ROP patients with the VEGF rs10434 A allele (GA + AA) exhibited higher risks of necrotizing enterocolitis (OR = 2.750; 95% CI, 1.119-6.759) and lower risk of bronchopulmonary dysplasia (OR = 0.390; 95% CI, 0.173-0.877) than those with GG homozygotes did. Conclusions: VEGF polymorphisms affect ROP risks differently in male and female infants. In female infants, VEGF rs3025035 with T alleles may predict ROP severity, and VEGF rs3025010 with C alleles may protect against severe ROP.

Surgical decisions and outcomes of rhegmatogenous retinal detachment during the coronavirus disease 2019 pandemic: Data from a tertiary referral center in Taiwan.

Purpose: To assess changes in surgical decisions and outcomes of rhegmatogenous retinal detachment (RRD) during the COVID-19 pandemic at a tertiary center in Taiwan. Methods: Patients undergoing pars plana vitrectomy (PPV) or scleral buckling (SB) for primary RRD during Taiwan's first wave of domestic COVID-19 cases surge between May and July 2021 (COVID cohort, n = 100) were compared to controls in the closest pre-COVID year, 2019 (pre-COVID cohort, n = 121). Results: The COVID cohort had significantly worse RRD presentation, received more PPV (alone or combined with SB (PPV + SB)) and less SB alone, and had comparable single-surgery anatomic success (SSAS) rates. In patients who underwent PPV, more underwent PPV + SB instead of PPV alone. The decision to combine SB in PPV surgery was significantly affected by the COVID pandemic (odds ratio [OR], 3.1860 [95% confidence interval (CI), 1.1487-8.8361]). However, a shorter duration of symptoms before the first presentation (0.9857 [95% CI, 0.9720-0.9997]) was the only factor related to SSAS, whereas the surgical method had no association. The SSAS rate remained close to or over 90% in patients with a duration of symptoms before surgery ≤4 weeks but dropped to 83.3% in patients with duration >4 weeks. Conclusion: During the COVID-19 pandemic, worse RRD presentations led to a shift in preference for PPV over SB alone as the primary surgery. The pandemic affected surgeons' decision to combine SB during PPV. Nevertheless, SSAS was only associated with the duration of symptoms but not with surgical methods.

Diagnosis and Treatment of Tubercular Uveitis in Taiwan - Consensus of Expert Panels.

There is currently a lack of guidelines with regard to tubercular uveitis (TBU) management in Taiwan. We therefore propose an evidence-based consensus on the management for TBU. The Taiwan Ocular Inflammation Society conducted a meeting that included nine ophthalmologist and one infection disease expert that focused on three broad areas of (1) nomenclature for TBU, (2) assessment and diagnosis for TBU, and (3) treatment of TBU. Brief literature review on TBU diagnosis and management was conducted that informed this panel meeting in order to make decisions on each consensus statements. In terms of our results, a consensus statements and recommendations for the diagnosis and management of TBU were developed. This consensus statement provides an algorithmic approach toward diagnosing and managing TBU. These statements are meant to enhance but not replace individual clinician-patient interactions and to facilitate real-world clinical practice improvement in terms of TBU patients care.
