RESUMO
INTRODUCTION: This study compared the efficacy of hydroxypropyl guar (HPG)/hyaluronic acid (HA) and carboxymethylcellulose (CMC)/HA lubricant eye drops for post-cataract surgery dry eye disease (DED). METHODS: This was a prospective, open-label, assessor-masked, parallel, randomized controlled study. Seventy patients with DED who underwent cataract surgery were randomized in a 1:1 ratio to receive 1-2 drops of HPG/HA or CMC/HA lubricant four times daily for 3 weeks. Efficacy assessments included changes from baseline in corneal fluorescein staining (CFS) score, Ocular Surface Disease Index score, Schirmer's test score (without anesthesia), tear break-up time, and central corneal sensitivity at weeks 1 and 3. RESULTS: There were 35 patients in each group. The HPG/HA group demonstrated superior improvements in CFS scores (expressed as means and standard deviations) to the CMC/HA group at week 1 ( - 1.0 [1.7] vs. - 0.1 [1.7], p = 0.039) and demonstrated comparable results at week 3 ( - 1.6 [1.8] vs. - 1.3 [1.9], p = 0.552). No statistical differences were observed in other secondary outcomes between groups at weeks 1 and 3 (p > 0.05). Only one adverse event was reported in this study, which occurred in the HPG/HA group. The AE of ocular hypertension was mild, deemed unrelated to the study treatment, and resolved within a week. CONCLUSIONS: The HPG/HA lubricant eye drops resulted in greater CFS scores at 1 week after treatment compared with CMC/HA drops. The HPG/HA and CMC/HA drops were safe and well tolerated. GOV IDENTIFIER: NCT06221345.
RESUMO
OBJECTIVES: To investigate the relationships among myopia treatment, decision regret, shared decision-making, and vision-related quality of life among parents of 6-12-year-old children with myopia. METHODS: An online Google Forms questionnaire was developed using a cross-sectional design and distributed between January 16 and August 22, 2023. Parents of 6-12-year-old children with myopia were recruited through school nurses working in Taiwan. The children's and parents' demographic data were collected. Study instruments included the Decisional Regret Scale, Shared Decision-Making, and Vision-Related Quality of Life questionnaires. Multivariable linear regression analysis was used to identify factors influencing vision-related quality of life. RESULTS: Of 350 parents contacted, 314 questionnaires were analyzed. Among the respondents, 77.39 % (n = 243) were mothers, and most were aged >40 years. The mean age of children at myopia diagnosis was 7.12 ± 1.24 years; 46.50 % had < - 1.0 diopters of refractive error. Atropine eye drops were the primary treatment; 17.71 % of children were prescribed orthokeratology for myopia control. Parents reported low levels of decision regret and moderate levels of shared decision-making and vision-related quality of life. Children's age, use of orthokeratology lenses, decision regret, and shared decision-making significantly influenced the vision-related quality of life reported by the parents, accounting for 22.5 % of the variance. CONCLUSION: The study's findings emphasize the importance of addressing decision regret and promoting shared decision-making in myopia treatment. Eye care professionals should discuss treatment options thoroughly before making decisions. Through shared decision-making, parents can make informed choices about treatments based on a comprehensive understanding of the benefits and drawbacks, ultimately benefitting children's vision health.
RESUMO
BACKGROUND: An impaired ocular surface presents substantial challenges in terms of planning for cataract surgery. As a multifactorial ocular disorder, dry eye disease (DED) is common in the general population and prevalent in patients scheduled for lens replacement surgery. Cataract surgery can exacerbate DED and worsen several ocular parameters. Timely diagnosis and appropriate treatment of DED are vital to ensuring positive ophthalmic surgical outcomes. This consensus report of the Taiwan Society of Cataract and Refractive Surgeons (TSCRS) regarding the management of DED before, during, and after cataract surgery highlights the gaps between clinical guidelines and several aspects of DED, including diagnostic testing, diagnostic criteria, and clinical practice treatment. METHODS: An expert panel of five specialists in the field of ophthalmology was recruited to develop consensus statements regarding the management of DED in both the general population and in patients undergoing cataract surgery in Taiwan. Two separate meetings of the five specialists, who were endorsed by the TSCRS, were convened for this purpose. A survey questionnaire consisting of binary or multiple-choice questions was developed through a consensus-driven formulation process. A percentage value was calculated for each statement, and a minimum of 60% agreement (equivalent to three out of five members) was required to achieve consensus. The second discussion meeting involved the presentation of the finalized consensus statements and concluded the consensus development process. Lastly, the finalized consensus statements were approved by all the experts, and the formulated recommendations for DED in the general population and prospective cataract surgery patients were accordingly presented. RESULTS: The optimal algorithm for managing DED in the general population and in patients scheduled for cataract surgery was developed to address the unmet needs of this cohort in Taiwan. CONCLUSION: This report provides recommendations for managing dry eye disease. It is essential to screen and confirm DED through endorsed questionnaires and tests and then diagnose it. Treatment and management of DED should follow a stepwise approach. Screening and diagnosing DED is also recommended before cataract surgery. After cataract surgery, relatively aggressive treatment strategies are recommended to manage DED effectively.

Study Objectives: To evaluate the association between obstructive sleep apnea (OSA) and dry eye disease (DED) and analyze the impact of Continuous Positive Airway Pressure (CPAP) on DED. Methods: This is a retrospective population-based case-control study. Patients who underwent polysomnography in Taiwan from March 1, 2009, to March 1, 2020, were identified from the database of a sleep center. Patients who were diagnosed with keratoconjunctivitis sicca or tear film insufficiency were included. Patients without data from Schirmer's test, lacking tear break-up time values, or with a history of refractive surgery, Sjögren's syndrome, ocular injuries, or a disability in eyelid closure were excluded. All patients with DED enrolled had DED in both eyes. OSA severity between patients with and without DED was compared. Results: In total, 86 patients with DED and 86 age-matched patients without DED were enrolled. Significant differences in apnea-hypopnea index values (patients with DED: 29.1 ± 23.4, patients without DED: 17.9 ± 20.2, P < 0.001), OSA severity (P < 0.001), and lowest oxygen saturation (P = 0.040) between patients with and without DED were observed. A multivariate logistic regression model indicated that the use of CPAP was independently associated with DED after adjustments for OSA severity. Patients undergoing CPAP were at greater risk of developing DED than those not undergoing CPAP (Odds ratio: 3.93, 95% confidence interval: 1.47-10.49, P = 0.006). Conclusion: OSA severity is associated with DED and might be attributed to the use of CPAP.
RESUMO
PURPOSE: The purpose of this study is to investigate visual and tomographic outcomes and complications of long-arc length intrastromal corneal ring segment (ICRS) implantation for the treatment of advanced keratoconus. MATERIALS AND METHODS: This retrospective study enrolled 10 eyes of 9 subjects. All patients received 320-degree ICRS (320-ICRS) implantation with femtosecond laser-assisted technique based on their advanced grading with preoperative high keratometry (K) value, asphericity (Q), and astigmatism. Medical records and corneal tomography changes of consecutive patients were reviewed at baseline, 1, and 3 months after treatment. RESULTS: There are 6 female and 3 male patients with a mean age of 29.6 ± 7.8 years in this study. Mean K (Km) reduced from 59.01 ± 5.81 D preoperatively to 50.7 ± 5.3 and 50.2 ± 3.66 postoperatively (after 1 month and 3 months respectively, P < 0.001). The changes in mean K, K1, K2, and maximum K (Kmax) reading were all statistically significant (all P < 0.001). Mean uncorrected distance visual acuity (UCVA) improved from 20/400 to 20/200. Mean best-corrected distance visual acuity (BCVA) improved from 20/100 to 20/60. Both UCVA and BCVA showed a trend of improvement at postoperative month 3, though insignificant in BCVA (P = 0.114). Mean Q improved from -1.59 ± 0.62 preoperatively to -0.48 ± 1.08 and -0.11 ± 1.04 postoperatively (after 1 month and 3 months respectively, P = 0.016, 0.002). No intraoperative or postoperative complications were observed. CONCLUSIONS: The present results suggest that implanting a 320-ICRS is a safe and effective procedure for treating patients with advanced keratoconus. Preoperative corneal measurements and the selection of types and thickness of ICRS are important to prevent unpredictable results.
RESUMO
This case discussed a significant ocular side effect, bilateral keratitis, which could be induced by afatinib, an irreversible epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI). We explored the disease progression of a 52-year-old, stage IV nasopharyngeal carcinoma male patient, who was under afatinib treatment and had experienced progressive bilateral eye dryness and tenderness on increasing afatinib from 40 mg every other day to 40 mg daily. Clinical examination noted bilateral visual acuity reduction, diffuse superficial punctate keratopathy in the right eye, and a central epithelial defect in the left eye. Seidel test results were negative for both eyes, with no corneal infiltration, lagophthalmos, anterior chamber cell precipitation, or retinal lesion. Symptoms subsequently resolved after reducing the frequency of afatinib used, along with intensive ocular hydration. In summary, this case highlighted afatinib's potential link to bilateral keratitis, and early afatinib dose adjustment with supportive medication could significantly reverse the condition.

Negative Pressure Wound Therapy (NPWT) is a commonly employed clinical strategy for wound healing, yet its early-stage mechanisms remain poorly understood. To address this knowledge gap and overcome the limitations of human trials, we establish an NPWT C57BL/6JNarl mouse model to investigate the molecular mechanisms involved in NPWT. In this study, we investigate the intricate molecular mechanisms through which NPWT expedites wound healing. Our focus is on NPWT's modulation of inflammatory immune responses and the concurrent orchestration of multiple signal transduction pathways, resulting in shortened coagulation time and reduced inflammation. Notably, we observe a significant rise in dickkopf-related protein 1 (DKK-1) concentration during NPWT, promoting the differentiation of Hair Follicle Stem Cells (HFSCs) into epidermal cells, expediting wound closure. Under negative pressure, macrophages express and release DKK-1 cytokines, crucial for stimulating HFSC differentiation, as validated in animal experiments and in vitro studies. Our findings illuminate the inflammatory dynamics under NPWT, revealing potential signal transduction pathways. The proposed framework, involving early hemostasis, balanced inflammation, and macrophage-mediated DKK-1 induction, provides a novel perspective on enhancing wound healing during NPWT. Furthermore, these insights lay the groundwork for future pharmacological advancements in managing extensive wounds, opening avenues for targeted therapeutic interventions in wound care.

PURPOSE: To examine the initial presenting symptoms in relation to sex and identify predictors of discordance between symptoms and signs of dry eye disease (DED) in Taiwan. DESIGN: Retrospective cross-sectional study. METHODS: This clinic-based cohort from a tertiary referral center in Taiwan included 1229 patients diagnosed with DED at Keelung Chang Gung Memorial Hospital in Taiwan between August 1, 2011, and July 31, 2018. Initial presenting symptoms were cross-sectionally and retrospectively collected. The composite score, indicating the discordance between symptoms and signs, was derived from the difference between the DED symptom severity score and the DED sign severity score. RESULTS: Of 1229 patients, 975 (79.3%) were female, with a mean age of 56.7 ± 14.9 years. Initial presenting symptoms didn't show significant sex differences (all P > .05). In multivariate analysis, predictors of higher symptom severity score than sign severity score included being female (P = .011) and having a surgical history of cataract (P = .037), pterygium, or conjunctivochalasis (P = .014). Conversely, older age (P < .001) and artificial tear use (P < .001) were significant predictors of a lower symptom severity score than sign severity score. CONCLUSIONS: Strong predictors of incongruity between DED symptoms and signs include age, gender, surgical history for cataract, pterygium or conjunctivochalasis, and artificial tear use. Ophthalmologists should prioritize symptoms for female patients and postsurgery cases. In addition, the absence of symptoms should not dismiss DED possibility in older adult patients and those using artificial tears. Notably, early recognition and enhancement of postoperative care can improve patient satisfaction and quality of life.

Chronic epithelial defects of the cornea, which are usually associated with severe dry eye disease, diabetes mellitus, chemical injuries or neurotrophic keratitis, as well as aging, are an unmet clinical need. CDGSH Iron Sulfur Domain 2 (CISD2) is the causative gene for Wolfram syndrome 2 (WFS2; MIM 604928). CISD2 protein is significantly decreased in the corneal epithelium of patients with various corneal epithelial diseases. Here we summarize the most updated publications and discuss the central role of CISD2 in corneal repair, as well as providing new results describing how targeting Ca2+-dependent pathways can improve corneal epithelial regeneration. This review mainly focuses on the following topics. Firstly, an overview of the cornea and of corneal epithelial wound healing. The key players involved in this process, such as Ca2+, various growth factors/cytokines, extracellular matrix remodeling, focal adhesions and proteinases, are briefly discussed. Secondly, it is well known that CISD2 plays an essential role in corneal epithelial regeneration via the maintenance of intracellular Ca2+ homeostasis. CISD2 deficiency dysregulates cytosolic Ca2+, impairs cell proliferation and migration, decreases mitochondrial function and increases oxidative stress. As a consequence, these abnormalities bring about poor epithelial wound healing and this, in turn, will lead to persistent corneal regeneration and limbal progenitor cell exhaustion. Thirdly, CISD2 deficiency induces three distinct Ca2+-dependent pathways, namely the calcineurin, CaMKII and PKCα signaling pathways. Intriguingly, inhibition of each of the Ca2+-dependent pathways seems to reverse cytosolic Ca2+ dysregulation and restore cell migration during corneal wound healing. Notably, cyclosporin, an inhibitor of calcineurin, appears to have a dual effect on both inflammatory and corneal epithelial cells. Finally, corneal transcriptomic analyses have revealed that there are six major functional groupings of differential expression genes when CISD2 deficiency is present: (1) inflammation and cell death; (2) cell proliferation, migration and differentiation; (3) cell adhesion, junction and interaction; (4) Ca2+ homeostasis; (5) wound healing and extracellular matrix; and (6) oxidative stress and aging. This review highlights the importance of CISD2 in corneal epithelial regeneration and identifies the potential of repurposing venerable FDA-approved drugs that target Ca2+-dependent pathways for new uses, namely treating chronic epithelial defects of the cornea.

PURPOSE: To evaluate the efficacy and safety of 0.1% cyclosporine A cationic emulsion (CsA CE) following prior treatment with 0.05% cyclosporine A anionic emulsion (CsA AE) in moderate to severe dry eye disease (DED). MATERIALS AND METHODS: We retrospectively identified patients with moderate-to-severe DED who had shown an inadequate response to twice-daily use of topical 0.05% CsA AE but showed a significant improvement after switching to 0.1% CsA CE daily. Dry eye parameters before and after CsA CE were evaluated by tear break-up time (TBUT), corneal fluorescein staining (CFS), cornea sensitivity, Schirmer's test without anesthetics, and Ocular Surface Disease Index questionnaire. RESULTS: Twenty-three patients, including ten patients with Sjogren syndrome and five patients with rheumatoid arthritis, were reviewed. After a 2-month course of treatment with topical 0.1% CsA CE, significant improvements were noted for CFS (P < 0.001), corneal sensitivity (P = 0.008), and TBUT (P = 0.01). Efficacy was similar in the autoimmune versus nonautoimmune group. 39.1% of patients reported treatment-related adverse events, while the majority was transient instillation pain. Visual acuity and intraocular pressure had no significant changes during the study. CONCLUSION: In patients with moderate to severe DED refractory to 0.05% cyclosporine, shifting to 0.1% cyclosporine showed improvement in objective signs but with lower treatment tolerability in the short term.
RESUMO
Purpose: The coronavirus disease 2019 (COVID-19) pandemic profoundly impacts lifestyle habits and myopia control in children worldwide. This study investigated the changes in eyecare habits, orthokeratology compliance, axial length, and time interval of follow-up visits during home confinement in the COVID-19 pandemic in Taiwan. Methods: This investigation was part of a prospective study undertaken to evaluate the effectiveness of a mobile application. A semi-structured telephone interview was conducted with parents retrospectively to document eyecare habits and myopia control during the COVID-19 home confinement. Results: Thirty-three children with myopia participated in the follow-up of orthokeratology lenses for 2 years. The children's time viewing digital devices such as tablets and televisions significantly increased during the COVID-19 pandemic (P < 0.05). An analysis using McNemar's test found that the proportional growth of axial length <0.2 mm in 2021 was significantly higher than that in 2020 (77.42% vs. 58.06%, P < 0.05). In the multivariate logistic regression analysis, onset <10 years of age (P = 0.001) and parents with high myopia (P < 0.001) were independent risk factors for the growth of axial length ≥0.2 mm in 2021. Conclusion: The suspension of face-to-face classes and after-school tutorials benefited myopic axial elongation in children during COVID-19 home confinement. The use of digital devices and staying indoors may not be the exclusive reasons for myopia progression. Educating parents about the influence of extra learning classes after school on myopia progression would be prudent.

INTRODUCTION: Chronic kidney disease (CKD) has been associated with accelerated retinal neurodegeneration. The purpose of this study is to evaluate the association between retinal neurodegeneration and the best-corrected visual acuity (BCVA) decline in patients with CKD. METHODS: Post hoc analysis of two prospective studies. Patients with CKD stage ≥ 3 were enrolled. Macular thickness, peripapillary retinal nerve fiber layer (pRNFL) thickness, and macular ganglion cell complex (GCC) thickness were measured by optical coherence tomography. Eyes were classified into three groups: Group 1, no GCC defect; Group 2, GCC defect confined to parafoveal area; and Group 3, GCC defects extending beyond the parafoveal area. Each group was matched for age, sex, axial length, lens status, and cataract grading. RESULTS: A total of 120 eyes (40 eyes in each group) from 120 patients (age 63.0 ± 10.3 years) were included. The logMAR BCVA was 0.076 ± 0.101, 0.100 ± 0.127, and 0.196 ± 0.191 in Group 1, 2, and 3, respectively. Group 3, but not Group 2, had a significantly worse BCVA than Group 1. In simple linear regression, parafoveal inner retinal thickness, pRNFL thickness, presence of pRNFL defect, GCC thickness, GCC global loss volume, GCC focal loss volume, and GCC defect extending beyond parafoveal area were associated with BCVA. Central subfield retinal thickness (CRT), parafoveal full retinal thickness, and parafoveal outer retinal thickness were not associated with BCVA. In backward stepwise linear regression, age and GCC defects extending beyond the parafoveal area were factors associated with BCVA. Moreover, GCC defect extending beyond parafoveal area was connected with worse BCVA in both phakic and pseudophakic subgroups. CONCLUSIONS: GCC defect extending beyond parafoveal area could be an independent biomarker associated with decreased BCVA in patients with CKD. However, macular thinning measured by CRT or parafoveal full retinal thickness might have low discriminative power in determining BCVA.
RESUMO
Purpose: To evaluate the longitudinal changes in the peripapillary retinal nerve fiber layer (pRNFL) in patients with chronic kidney disease (CKD). Methods: In this prospective cohort study, the CKD group consisted of patients with CKD stage ≥ 3. Age-matched healthy controls were enrolled at a 1:4 ratio. Spectral-domain optical coherence tomography was used to measure the pRNFL at baseline, 1 year, and 2 years. Within-group longitudinal changes and between-group comparisons were performed using linear mixed models. Results: Overall, 152 patients with CKD and 40 controls were included (mean ages, 62.8 ± 9.1 years vs. 63.0 ± 9.3 years; P = 0.931). The CKD group showed faster loss of pRNFL than the control group (-0.87 µm/y vs. -0.26 µm/y; P = 0.004). Subgroup analysis found that the rate of pRNFL change was -0.41 µm/y in stage 3a CKD, -0.74 µm/y in stage 3b, -0.98 µm/y in stage 4/5, and -1.38 µm/y in end-stage renal disease. Multiple linear regression analysis revealed that CKD stage (coefficient = -0.549; 95% confidence interval [CI], -0.966 to -0.131; P = 0.010), hypertension (coefficient = -1.557; 95% CI -3.013 to -0.101; P = 0.036), and rim area (coefficient = -1.505; 95% CI, -2.940 to -0.070; P = 0.040) were factors associated with the pRNFL change over 2 years. Conclusions: Patients with CKD experienced faster pRNFL loss than healthy controls did. Severity of CKD, hypertension, and rim area were independent factors associated with the loss of pRNFL. Translational Relevance: This study contributes to our understanding of retinal neurodegeneration in normal aging and in patients with chronic kidney diseases.

Purpose: To examine tear function in patients with diabetes mellitus (DM). Design: Systematic review and meta-analysis. Method: We searched Embase and PubMed from database inception to March 16, 2022. We included observational studies that compared tear function between patients with and without DM. Tear function was measured using invasive tear breakup time (ITBUT) and Schirmer's 1 test. Pooled results are presented as standard mean difference (SMD) with 95% confidence interval (CI) based on random-effects models. Results: We included 59 studies (7,234 eyes) comparing the tear function between patients with and without DM. This meta-analysis indicated that patients with DM had worse tear function than those without DM (ITBUT: SMD: -0.98, 95% CI: -1.27 to -0.69; Schirmer's 1 test: SMD: -0.45, 95% CI: -0.64 to -0.26), and the results remained consistent in patients with different types of DM (e.g., type 1 DM and type 2 DM) and from different ethnic backgrounds (e.g., Asian vs. non-Asian). Patients with DM under poor glycemic control had worse tear function than those of the non-DM group (ITBUT: SMD: -1.26, 95% CI: -1.86 to -0.66; Schirmer's 1 test: SMD: -0.25, 95% CI: -0.48 to -0.02), whereas there were no significant differences in tear function between patients with DM under optimal glycemic control and non-DM groups. Conclusions: We found that patients with type 1 or type 2 DM had significantly reduced tear function. The level of tear function could be determined by glycemic control, and therefore, our findings suggest that glycemic control in patients with DM is critical for maintaining tear function.

Staphylococcus lugdunensis endophthalmitis is an uncommon intraocular infection with potentially visually devastating consequences. S. lugdunensis endophthalmitis have been reported following cataract surgery, trauma, intravitreal injections of anti-vascular endothelial growth factor agents and dexamethasone implant. We report four cases of postoperative S. lugdunensis endophthalmitis after cataract extraction (three patients) and combined pars plana vitrectomy and cataract extraction (one patient). The onset of presentation of endophthalmitis was acute (within 2 weeks) in two patients, subacute (2 to 6 weeks) in one patient, and chronic (more than 6 weeks) in one patient. All patients had presenting visual acuity (VA) of hand motions or worse and were treated with pars plana vitrectomy with intravitreal antibiotics. The final VA was 20/50 in two patients, 4/200 in one patient with pre-existing myopic maculopathy, and no light perception in one patient with retinal detachment. In antibiotic susceptibility testing, S. lugdunensis isolates were resistant to penicillin (3/4, 75%), but all were susceptible to vancomycin, oxacillin, teicoplanin, tigecycline, and sulfamethoxazole-trimethoprim. S. lugdunensis may be associated with acute or chronic endophthalmitis. Favorable visual outcomes can be achieved with prompt diagnosis and management.
RESUMO
Purpose: To investigate the risk and protective factors of dry eye disease (DED) in patients with type II diabetes mellitus (DM). Design: A retrospective cohort study using Chang- Gung research database collecting data from 2005 to 2020. Methods: Patients with type II DM were included, and those with previous ocular diseases were excluded. Ten thousand twenty nine developed DED (DED group), and 142,491 didn't (non-DED group). The possible risk and protective factors were compared and analyzed using the logistic regression model. Results: A majority of the DED group were female with significantly higher initial and average glycated hemoglobin levels, and higher incidence of diabetic neuropathy and retinopathy. In conditional logistic regression model, advanced age was a risk factor. After adjusting for sex, age, and DM duration; average glycated hemoglobin level, diabetic neuropathy, retinopathy, and nephropathy with eGFR 30 ~ 59 and intravitreal injection, vitrectomy, pan-retinal photocoagulation, and cataract surgery were contributing factors of DED. Considering antihyperglycemic agents, DPP4 inhibitor, SGLT2 inhibitor, GLP-1 agonist, and insulin monotherapy and dual medications combining any two of the aforementioned agents were protective factors against DED compared with metformin alone. In the monotherapy group, SLGT2 inhibitor had the lowest odds ratio, followed by GLP1 agonist, DPP4 inhibitor, and insulin. Conclusions: DED in patients with DM is associated with female sex, advanced age, poor diabetic control, microvascular complications and receiving ocular procedures. GLP-1 agonist, SGLT-2 inhibitor, DPP4 inhibitor, and insulin are superior to metformin alone in preventing DM-related DED. A prospective randomized control trial is warranted to clarify our results.
RESUMO
Importance: Sodium-glucose cotransporter 2 (SGLT2) inhibitors have been found to improve low-grade systemic and tissue inflammation; however, the association between SGLT2 inhibitor use and the incidence of dry eye disease (DED) has not been explored. Objective: To investigate the association between SGLT2 inhibitor use and dry eye disease in patients with type 2 diabetes (T2D). Design, Setting, and Participants: A retrospective cohort analysis of the largest multi-institutional electronic medical records database in Taiwan was conducted to identify patients with T2D newly receiving SGLT2 inhibitors or glucagonlike peptide-1 receptor agonists (GLP-1 RAs) from 2016 to 2018. Data analysis was performed from March 1 to May 31, 2022. Propensity scores with inverse probability of treatment weighting were generated to enable homogeneous comparisons between the 2 groups. Exposures: Treatment with SGLT2 inhibitors or GLP-1 RAs. Main Outcomes and Measures: Incident dry eye disease, which was defined by clinical diagnoses, plus the related drug prescription. Cox proportional hazards regression models were used to estimate hazard ratios with 95% CIs for the risk of DED. Results: A total of 10â¯038 and 1077 T2D patients newly receiving SGLT2 inhibitors (mean [SD] age, 59.5 [12.1] years; 5689 [56.7%] men) or GLP-1 RAs (mean [SD] age, 58.5 [41.2] years; 587 [54.5%] men), respectively, were included in the analysis. The incidence of DED was lower in patients newly receiving SGLT2 inhibitors (9.0 events per 1000 person-years) compared with those receiving GLP-1 RAs (11.5 events per 1000 person-years), yielding a hazard ratio of 0.78 (95% CI, 0.68-0.89). Subgroup analyses indicated that the lowered DED risks associated with SGLT2 inhibitors in patients with T2D were similar across different age, sex, blood glucose level, and kidney function groups. Results from the sensitivity analyses (including the propensity score-matching approach, on-treatment analyses, and different follow-up periods of 1, 2, and 3 years) were similar to the main analyses. Conclusions and Relevance: The findings of this study suggest that patients with T2D newly receiving SGLT2 inhibitors may have a lower risk for DED compared with those receiving GLP-1 RAs. Prospective studies are needed to analyze these results.

The association between myopia control efficacy in children treated with orthokeratology and corneal epithelial thickness is still unknown. The aim of this study was to explore the corneal epithelial thickness and its association with axial length changes in children treated with orthokeratology. This retrospective cohort study enrolled children aged from 9 to 15 years who had received orthokeratology for myopia control and had been followed up for at least 1 year. Anterior segment optical coherence tomography was performed to generate wide epithelial thickness maps of the patients. Annual axial length changes were calculated from the axial length at 6 months after the initiation of orthokeratology lens wear and at final measurements. Corneal epithelial thickness data were obtained from 24 sectors and a central 2 mm zone of the wide epithelial thickness map. Associations between annual axial length changes and corneal epithelial thickness for each sector/zone of the wide epithelial thickness map, and orthokeratology treatment data were determined by generalized estimating equations. Finally, a total of 83 eyes of 43 patients (mean age 11.2 years) were included in the analysis. The mean annual axial length change was 0.169 mm; when regressing demographic and ortho-k parameters to mean annual axial length changes, age and target power were both negatively associated with them (ß = -14.43, p = 0.008; ß = -0.26, p = 0.008, respectively). After adjusting for age and target power, the annual axial length changes were positively associated with the corneal epithelium thickness of IT1, I1, SN2, and S2 sectors of the wide epithelial thickness map, and negatively with that of the I3 sector. In conclusion, we identified associations between annual axial length changes and the corneal epithelium thickness of certain sectors in children treated with orthokeratology. This may facilitate the design of orthokeratology lenses with enhanced efficacy for myopia control.
RESUMO
PURPOSE: To investigate the clinical settings and features, management, and visual outcomes of exogenous bacterial endophthalmitis with retinal vasculitis and posterior pole preretinal exudates. METHODS: Retrospectively reviewed records for 40 eyes of 40 patients. RESULTS: Retinal vasculitis was identified with focal type in eight eyes and diffuse type in 32 eyes. Posterior pole preretinal exudates were identified with discrete type in 23 eyes and condensed type in 17 eyes. Final VA was 20/200 or better in 23 of 40 eyes (57.5%). Multivariate linear regression revealed that condensed posterior pole preretinal exudates (P =.005) and ocular hypertension (P =.012) were the significant independent factors for poor visual outcomes. CONCLUSIONS: Condensed posterior pole preretinal exudates and ocular hypertension are critical prognostic factors for poor visual outcomes.
