RESUMEN

PURPOSE: To compare the efficacy of brolucizumab, half-dose PDT, and aflibercept in treating chronic central serous chorioretinopathy (CSC). METHODS: A retrospective cohort study with chronic CSC patients who underwent intravitreal injection of one shot of brolucizumab or aflibercept in the first 3 months, followed by pro re nata regimens or a single session of half-dose PDT, was retrospectively reviewed. The primary outcome measure was the proportion of eyes that achieved complete absorption of retinal fluid without requiring any rescue treatment. Secondary outcomes included changes in best-corrected visual acuity (BCVA), central retinal thickness (CRT), and central choroidal thickness (CCT). RESULTS: A total of 54 consecutive patients were included in this study with 18 patients in each group. At months 1 and 2, the brolucizumab group exhibited the highest rate of complete retinal fluid resolution (61% and 77%), followed by the half-dose PDT group (56% and 72%), and lowest in the aflibercept group (28% and 33%), with statistically significant differences noted at month 2 (P = 0.012). The brolucizumab group also demonstrated the most significant reduction in CCT at months 1 and 2 among the three groups (P = 0.007 and 0.001). Recurrence of retinal fluid in the brolucizumab groups was predominantly observed at month 3. Conversely, the half-dose PDT group exhibited the most favorable anatomical results starting from month 3. Notably, mild vitritis was observed in one case from the brolucizumab group. CONCLUSIONS: Single injection of brolucizumab demonstrates trends of faster regression of persistent residual retinal fluid, greater CCT and CRT decline, and matched BCVA compared to half-dose PDT in the short term.

RESUMEN

INTRODUCTION: Compare the anatomical and functional outcomes, operation duration, and complication rates between standard scleral buckling (SSB) and chandelier-assisted scleral buckling (CSB) for phakic eyes with rhegmatogenous retinal detachment (RRD). METHODS: PubMed, Embase, and Cochrane Library databases were searched from inception to June 2024. The primary endpoint will be set as a final success. The secondary endpoint will be primary success, operation time, and final BCVA. RESULTS: Our meta-analysis showed that there is no statistical difference between CSB and SSB for the final success rate (RR = 1.00, 95% CI = 0.97-1.03). For the primary success rate, there is no statistical difference between CSB and SSB (RR = 1.00, 95% CI = 0.94-1.06). For operation time, our meta-analysis showed that the CSB group is less than the SSB group (pooled MD = -15.8, 95% CI = -22.60 to -9.00). For postoperative complications, our study shows that the CSB group presented with lower pooled risk than the SSB group (RR = 0.59, 95% CI = 0.41-0.89). There is a trend that the ERM formation risk is higher in the CSB group if there is no routine suture for the sclerotomy (p = 0.08). CONCLUSION: CSB showcases a significantly reduced operation duration and less postoperative complication in contrast to the SSB group, maintaining comparable primary and ultimate anatomical success rates as well as final BCVA.

RESUMEN

Self-stigma is detrimental to psychosocial well-being and the recovery journey among people living with depression. However, there has been limited research exploring the experience of stigma internalization when depression runs in families. This study aims to address this gap by (1) characterizing the manifestations of self-stigma among individuals living with depression whose parent(s) also have depression and (2) exploring the potential mechanisms underlying the impact of parental depression on self-stigma. Essential principles of the constructivist grounded theory approach were adopted to collect data through in-depth interviews with 27 participants aged 15-30, living in Mainland China. Many participants perceived depression running in their family as an endless disaster and an incurable illness. These beliefs further led to stigmatizing emotions (such as suppression, anger, and guilt) and behaviors (such as concealment and social withdrawal). Participants also highlighted ambivalent intergenerational relationships, tense family atmospheres, lower parental emotional involvement and support, and a lack of family flexibility due to parental depression. Furthermore, parental depression impacted participants' self-stigma by interfering with family relationships, family functioning, and parenting styles. It also shaped their perceptions of family, illness attribution, and public stigma. Additionally, parental depression had an impact on participants' social functioning, self-esteem, and personality, making them more susceptible to self-stigma. This study emphasizes the crucial role that the family plays in the internalization of stigma among individuals living with depression. It suggests that family dynamics, rather than family structure or economic backgrounds alone, shape this process.

RESUMEN

Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly worldwide. The prevalence and phenotypes of AMD differ among populations, including between people in Taiwan and other regions. We performed a genome-wide association study to identify genetic variants and to develop genetic models to predict the risk of AMD development and progression in the Taiwanese population. In total, 4039 patients with AMD and 16,488 non-AMD controls (aged ≥ 65 years) were included. We identified 31 AMD-associated variants (p < 5 × 10-8) on chromosome 10q26, surrounding PLEKHA1-ARMS2-HTRA1. Two genetic models were constructed using the clump and threshold method. Model 1 included the single nucleotide polymorphism rs11200630 and showed a 1.31-fold increase in the risk of AMD per risk allele (95% confidence interval (CI) = 1.20-1.43, p < 0.001). In model 2, 1412 single-nucleotide polymorphisms were selected to construct a polygenic risk score (PRS). Individuals with the top 5% PRS had a 1.40-fold higher AMD risk compared with that of individuals with a PRS in the bottom quartile (95% CI = 1.04-1.89, p = 0.025). Moreover, the PRS in the upper quartile was related to a decreased age at AMD diagnosis by 0.62 years (95% CI = -1.15, -0.09, p = 0.023). Both genetic models provide useful predictive power for populations at high risk of AMD, affording a basis for identifying patients requiring close follow-up and early intervention.

RESUMEN

This study examined whether mentorship could promote young gay men's identities and well-being, and whether a mentor's sexual orientation matters. A randomized control trial compared outcomes across three conditions: Arm A (a mentee matched with a sexual minority mentor), Arm B (a mentee matched with a heterosexual mentor), and a control arm receiving psychoeducation only. A community sample of 60 mentees aged 18-25 years was randomly allocated to the three arms and completed questionnaires at baseline, 3 months into the intervention, and at the end of the 6-month program. Fifteen mentees recounted their mentoring experiences through in-depth interviews. Linear mixed effects models showed that for both intervention and control conditions, internalized homonegativity declined while resilience, loneliness, and body acceptance improved over time. No time and group interactions were found. Meanwhile, a mentor's sexual orientation did not drive differential quality and outcomes of mentorship. Interviewees cited various benefits of mentorship, including providing companionship, enriching connection with lesbian, gay, bisexual (LGB) communities, and adding knowledge and perspectives of LGB lives and identities. Although quantitative data did not support any exclusive benefits of mentorship, most mentees recognized mentorship as a vital source of affirmation and companionship. Implications for research and mentoring programs are discussed.

RESUMEN

PURPOSE: To investigate whether patients with central serous chorioretinopathy (CSC) have increased risk of developing glaucoma. METHODS: Patients diagnosed with CSC between 1 January 2008 and 31 December 2018 were included in this study using data from the Taiwanese National Health Insurance Research Database (NHIRD). The CSC cohort was matched with a non-CSC cohort using the propensity score matching method, based on sex, age (in 10-year intervals), index date year, comorbidities, and steroid use, resulting in equal numbers of patients in both cohorts. Patients were followed up until 31 December 2019 or until they were withdrawn from the NHIRD. The incidence of glaucoma was compared between the two cohorts using the Cox regression model, and the risk of developing glaucoma was estimated using the Kaplan-Meier method. RESULTS: After adjusting for sex, age, comorbidities, and steroid use, the CSC cohort showed a significantly higher risk of developing glaucoma compared to those without CSC (adjusted HR = 3.99; 95% CI = 3.44-4.62). The cumulative incidence of glaucoma in the CSC cohort was also significantly higher than in the non-CSC cohort (log-rank test, p < 0.001). Among the glaucoma subtypes, normal tension glaucoma had the highest risk (adjusted HR = 5.79; 95% CI = 3.41-9.85), followed by primary open-angle glaucoma (adjusted HR = 2.77; 95% CI = 2.12-3.62). CONCLUSIONS: In conclusion, our study shows that CSC patients are at a higher risk of developing glaucoma, especially NTG. Awareness and regular glaucoma screenings are essential for patients with CSC.

RESUMEN

Background and Objectives: The identification of possible biomarkers that can predict treatment response among DME eyes is important for the individualization of treatment plans. We investigated optical coherence tomography (OCT)-based biomarkers that may predict the one-year real-life outcomes among diabetic macular edema (DME) eyes following treatment by intravitreal ranibizumab (IVR) injections. Materials and Methods: A total of 65 eyes from 35 treatment-naïve patients with DME treated with ranibizumab injection were recruited. Best-corrected visual acuity (BCVA), central retinal thickness (CRT), intraocular pressure (IOP), and OCT scans were retrospectively recorded at baseline before treatment and at 3 months, 6 months, and 12 months after treatment. The OCT scans were evaluated for biomarkers of interest, which included central retinal thickness (CRT), amount and locations of hyperreflective foci (HRF), subretinal fluid (SRF), intraretinal cysts (IRC), large outer nuclear layer cyst (LONLC), ellipsoid zone disruption (EZD), disorganization of retinal inner layers (DRIL), hard exudates (HE), epiretinal membrane (ERM), and vitreomacular interface (VMI). Correlations between these OCT biomarkers and outcome measures (visual and structural) were statistically analyzed. Results: A total of 65 eyes from 35 patients with DME were enrolled. The mean age was 64.2 ± 10.9 years old. Significant improvement in terms of mean BCVA (p < 0.005) and mean CRT was seen at final follow-up compared to baseline. The biomarkers of DRIL, LONLC, and SRF were found to be predictive for at least 50 µm CRT reduction after treatment (with odds ratio of 8.69, 8.5, and 17.58, respectively). The biomarkers of IRC, LONLC, and SRF were predictive for significant improvement in terms of BCVA and CRT after treatment. Finally, the number of HRF was predictive for both BCVA improvement and a CRT reduction of less than 100 µm after treatment. No serious complications were reported during the study. Conclusion: Our study demonstrated the utility of OCT biomarkers as therapeutic predictors of ranibizumab treatment among DME eyes.

RESUMEN

As a common experience for sexual minority individuals, sexual orientation concealment has complex implications. Self-determination theory (SDT) and previous studies suggest a mediation path where hiding sexual orientation is associated with well-being through eroding lesbian, gay, bisexual-specific authenticity and inducing loneliness. However, this relationship has rarely been examined using longitudinal data. This study also built on minority stress theory to determine whether the psychological process of concealment operates differently as a function of perceived acceptance in different contexts. A community sample of 636 sexual minority individuals in Hong Kong (48.3% men, 50.5% women, and 1.3% transgender and nonbinary individuals; mean age = 25.36 years) was recruited through lesbian, gay, bisexual, and transgender (LGBT) social media, nongovernmental organizations, and social venues to complete a baseline and 1-year follow-up survey. The results showed that loneliness mediated the relationship between concealment and well-being. Moreover, the mediation path from concealment to well-being via loneliness was moderated by the perceived LGBT-friendliness of the family. The negative association between concealment and well-being was only significant when the family was perceived as supportive of sexual and gender minorities. The study findings elucidated the complex mechanisms involved in the adverse outcomes of sexual orientation concealment and highlighted the importance of loneliness and family context when working with sexual minority clients on their concerns over sexual orientation concealment.

RESUMEN

This prospective comparative case series aims to compare best-corrected visual acuity (BCVA), retinal microvasculature, and retinal structural changes in patients treated with either ranibizumab or aflibercept for macular edema (ME) secondary to treatment-naïve branch retinal vein occlusion (BRVO) by optical coherence tomography angiography (OCTA). Ten patients were enrolled with macular capillary density of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) and foveal avascular zone (FAZ) measured in both eyes before and after treatment. Final central retinal thickness and BCVA improved significantly (p < 0.05), and densities of SCP and DCP of BRVO sectors were significantly lower at baseline than fellow eye counterparts and remained persistently lower during treatment, particularly in the aflibercept group (p < 0.05). SCP density, DCP density of both BRVO sectors (p = 0.0001, p < 0.0001), and non-BRVO sectors (p < 0.0001, p < 0.0001) were significantly correlated with final BCVA for diseased eyes. Using multivariate general linear model analysis, and including OCTA parameters only, but not all of the available clinical data, DCP density of BRVO sectors in both eyes was the most predictive factor for final visual outcome (probability p < 0.0001). OCTA offered further qualitative and quantitative evaluation of treatment-naïve BRVO. Judging by OCTA parameters, not only in the diseased eye but also in the fellow eye, DCP density of BRVO sectors was the most predictive factor of final visual outcome.

RESUMEN

BACKGROUND: Deprivation amblyopia is a great concern in hyperplastic persistent pupillary membranes (PPM) which blocked visual axis. Other ocular abnormality may accompany and further hinder the visual development of the infants. We evaluate the long-term visual prognosis and complications in patients with dense PPM and other associated abnormalities treated with early surgical intervention and timely visual rehabilitation. METHODS: Medical records of patients with surgical removal of PPM from 2000 to 2020 and also receiving visual rehabilitation were retrospectively reviewed. Besides visual axis blocked PPM, patients combined with other amblyopic risk factors or ocular abnormalities were included. Due to preparation for subsequent lens extraction if an underlying cataract was present, the surgical settings including the instruments and wound direction were similar to cataract surgery. All patients were enrolled in a visual rehabilitation program as soon as possible. The results including sex, age, timing of operation, initial and final visual acuity, refractive errors, and complications were recorded. RESULTS: Seven cases of five patients were included in this case series. Mean age at surgery was 42.3 ± 21.1 months (range, 5 to 66 months) and the post-operative follow-up period was 4.9 years (range, 1.2 to 8.2 years). The patient age at time of surgery ranged from 2.5 months to 2.5 years (mean, 14 months). Mean postoperative follow-up was 5.3 years (range, 2.5-8 years). There were no intra-operative and post-operative complications. Final BCVA varied with a mean value of 0.29 logMAR (range, 0 to 1 logMAR). An associated ocular abnormality of ametropia and strabismus led to the best visual prognosis. CONCLUSIONS: In patients with PPM, there were no significant complications in any patient using our technique. The surgical settings are easier to handle and more familiar with pediatric surgeons. Besides deprivation with patching, early PPM intervention and timely visual rehabilitation achieve the best visual prognosis in patients associated with risk of ametropic and strabismic amblyopia. TRIAL REGISTRATION: This retrospective, interventional case series study was conducted at China Medical University Hospital between April 1, 2000 and April 31, 2020. (IRB number: CMUH109-REC2-069 ).
