RESUMO
OBJECTIVE: To assess the rate and risk factors for reactivation of retinopathy of prematurity (ROP) after intravitreal injection (IVI) of antivascular endothelial growth factor (VEGF) agents. STUDY DESIGN: Infants who received IVI therapy between 2017 and 2022 were enrolled and divided into 2 groups: those with and without ROP reactivation. Information on ROP variables and patient variables were analyzed using multivariable logistic regression. RESULTS: A total of 114 infants with 223 eyes were enrolled in the study. The ROP reactivation rate was 11.4% of infants (9.9% of eyes). The mean duration of reactivation was 84 ± 45 days. Among the 223 eyes treated with IVI, reactivation rates were 6% for bevacizumab, 13.9% for aflibercept, and 22.2% for ranibizumab. A multivariable regression model showed that ranibizumab was an independent risk factor (OR 11.4, P = .008) for reactivation. Other risk factors included infants with periventricular leukomalacia (OR 13.8, P = .003), patent ductus arteriosus ligation (OR 10.7, P = .032), and infants who still required invasive mechanical ventilation on the day of IVI therapy (OR 7.0, P = .018). CONCLUSIONS: All anti-VEGF agents carry a risk of ROP reactivation, with the risk being greater with ranibizumab 0.25 mg than with bevacizumab 0.625 mg. Reactivation of ROP should be assessed vigilantly, especially in those infants with increased risks. Future research to determine the optimal anti-VEGF selection and dosage in high-risk infants is warranted.
RESUMO
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.

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.

PURPOSE: To evaluate choroidal changes over time in school-age children with a history of prematurity. METHODS: A study of 416 eyes of 208 eligible participants, including 88, 190, 36, 56, and 46 eyes in the full-term control, preterm, spontaneously regressed retinopathy of prematurity, intravitreal bevacizumab (injection of bevacizumab)-treated retinopathy of prematurity, and laser-treated retinopathy of prematurity groups, respectively, were enrolled in this study. The choroidal thickness was measured 4 times at 6-month intervals using optical coherence tomography. RESULTS: Of all the groups, the laser-treated children had the thinnest choroid compared with full-term children (-52.3 µ m, P = 0.04). Preterm children exhibited greater attenuation in choroidal thickness over time than did full-term children (-6.3 ± 26.9 and -1.1 ± 12.8 µ m/year, P = 0.03), whereas no difference was observed between injection of bevacizumab and laser treatments (-4.6 ± 18.9 and -2.0 ± 15.7 µ m/year, P = 0.46). In all groups, the changes in axial length were negatively associated with the changes in choroidal thickness (all P < 0.05). 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 injection of bevacizumab and laser treatments. Axial elongation was associated with choroidal thinning in school-age children.

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.

PURPOSE: Determine whether intravitreal injection of bevacizumab (IVB) exerts long-term effects on neurodevelopmental outcomes in children with retinopathy of prematurity (ROP) when reaching the age of 8 years. METHODS: We enrolled 277 children. Patients were stratified into the groups full-term, preterm without ROP, ROP without treatment, or ROP with treatment, based on gestational age (GA) and ROP status. Children under GA of 37 weeks were considered premature. Patients' cognitive outcomes were evaluated using Full-Scale Intelligence Quotient (FIQ) (full score and percentile) generated by the Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) every 1 to 2 years. RESULTS: At the mean age of 7.8 years, ROP without and with treatment groups demonstrated lower FIQ scores and percentiles, compared with full-term and premature groups (both p<0.05). FIQ scores and percentiles didn't significantly differ between patients who received different treatments for ROP (full score p=0.19; percentile p=0.37). After adjusting for GA, LogMAR best corrected visual acuity (BCVA) was negatively associated with FIQ scores (p=0.0008) and percentiles (p=0.0002). CONCLUSIONS: At the mean age of 8 years, patients with ROP undergoing IVB didn't exhibit worse cognitive outcomes than those who underwent laser photocoagulation or both treatments. GA and BCVA correlated with cognitive development in children.
RESUMO
PURPOSE: The purpose of our study is to assess the clinical performance of the DiveScope, a novel handheld histopathologic microscope in rapidly differentiating glioma from normal brain tissue during neurosurgery. METHODS: Thirty-two ex vivo specimens from 18 patients were included in the present study. The excised suspicious tissue was sequentially stained with sodium fluorescein and methylene blue and scanned with DiveScope during surgery. The adjacent tissue was sent to the department of pathology for frozen section examination. They would eventually be sent to the pathology department later for hematoxylin and eosin staining for final confirmation. The positive likelihood ratio, negative likelihood ratio, sensitivity, specificity, and area under the curve of the device were calculated. In addition, the difference in time usage between DiveScope and frozen sections was compared for the initial judgment. RESULTS: The sensitivity and specificity of the DiveScope after analyzing hematoxylin and eosin -staining sections, were 88.29% and 100%, respectively. In contrast, the sensitivity and specificity of the frozen sections histopathology were 100% and 75%, respectively. The area under the curve of the DiveScope and the frozen sections histopathology was not significant ( P =0.578). Concerning time usage, DiveScope is significantly much faster than the frozen sections histopathology no matter the size of tissue. CONCLUSION: Compared with traditional pathological frozen sections, DiveScope was faster and displayed an equal accuracy for judging tumor margins intraoperatively.

AIM: To develop and validate the Visual Function Battery for Children with Special Needs (VFB-CSN). METHOD: This was a scale development and validation study with (1) construct and item generation and (2) evaluations of interrater reliability, acceptability, and content, ecological, and convergent validities. RESULTS: Children with special needs were recruited for the reliability (n = 32) and validity (n = 95) investigations. The construct and items were generated based on literature review and an expert panel. We constructed eight categories, namely visual reflex, ocular muscle balance, visual acuity, oculomotor, visual field, contrast sensitivity, colour/form vision, and visual attention. Both functional assessment and standardized tests were adopted. The reliabilities were high for the whole VFB-CSN (intraclass correlation coefficient [ICC] = 0.90, 95% confidence interval [CI] = 0.80-0.90) and good for the oculomotor, contrast sensitivity, and colour/form vision (ICC = 0.80-0.86, 95% CI = 0.50-0.93). Correlations between the VFB-CSN and the Functional Vision Questionnaire were strong and acceptable for the contrast sensitivity, acuity, and colour/form vision (r = 0.79, r = 0.69, r = 0.69, r = 0.70 respectively). The correlation between the VFB-CSN and standardized visual acuity test was acceptable (r = -0.72). INTERPRETATION: The VFB-CSN is a reliable and valid multifaceted battery for children with special needs. Acceptable psychometric properties were also found for the acuity and contrast sensitivity. WHAT THIS PAPER ADDS: The Visual Function Battery for Children with Special Needs (VFB-CSN) can measure several types of visual function. The VFB-CSN also measures varying degrees of visual impairment in children with special needs. The VFB-CSN provides functional assessment and quantitative measurement for children with disability and difficulty in cooperating on standardized tests.

Pars plana vitrectomy (PPV) is the main treatment modality for patients with severe diabetic retinopathy. With the development of systems for microincision, wide-angle viewing, digitally assisted visualization, and intraoperative optical coherence tomography, contemporary PPV for diabetic retinopathy has been performed on a wider range of indications than previously considered. In this article, we reviewed, in conjunction with our collective experiences with Asian patients, the applications of new technologies for PPV in eyes with diabetic retinopathy and highlighted several important procedures and entities not generally reiterated in the literature, in order for vitreoretinal surgeons to optimize their approaches when facing the challenges imposed by the complications in diabetic eyes.

PURPOSE: To report the outcomes of the Peeling and Internal Limiting Membrane Reposition (PAIR) technique in myopic foveoschisis. METHODS: A retrospective case series of eyes with myopic foveoschisis that underwent vitrectomy and PAIR. Visual acuity, fundus photographs, and optical coherence tomography measurements were obtained and analyzed. Data are presented as medians (ranges). RESULTS: A total of seven eyes underwent PAIR and were followed up for 339 days (188-436 days). No intraoperative complications were noted. One eye exhibited postoperative macular hole formation, but the hole was healed through fluid-gas exchange. At the last follow-up, the visual acuity had improved from 20/66 (20/332-20/40) to 20/40 (20/100-20/25), and the central foveal thickness had decreased from 576 µ m to 269 µ m. A repositioned internal limiting membrane (ILM) was observed in six of the eyes, and inner retinal dimples were noted in only two eyes. However, retinal wrinkles under the repositioned or perifoveal ILM were noted in five eyes. CONCLUSION: The PAIR technique relieved traction, restored the ILM, and achieved functional and morphological improvement in eyes with myopic foveoschisis. Limited occurrence of inner retinal dimples and retinal thinning was noted, but retinal wrinkles occurred, likely due to ILM contracture.

BACKGROUND/PURPOSE: To evaluate clinical outcomes and assess genotype-phenotype correlations in patients with familial exudative vitreoretinopathy (FEVR). METHODS: Clinical charts of 40 patients with FEVR were reviewed. FEVR was staged per Pendergast and Trese, and retinal dragging and folds further classified per Yaguchi et al. We performed whole-exome sequencing and compared clinical characteristics between genetic-positive and genetic-negative groups. RESULTS: The mean duration of follow-up was 5.4 years (range: 0.33, 15) for genetic-positive and 6.9 (range: 1, 20) for genetic-negative patients. The mean age at diagnosis was 5.6 years (0.25, 27) for genetic-positive and 6.0 (0, 32) for genetic-negative patients. Genetic-positive patients reported 100% full-term births and genetic-negative patients reported 45% full-term births ( P = 0.0012). There were more patients with retinal folds with all major vessels affected (Yaguchi's Group 4) in genetic-positive compared with genetic-negative patients (21.4% vs. 2.6%, P = 0.045). TSPAN12 was the most common (57.1%) genetic mutation in our population of which 50% exhibited asymmetric presentation. CONCLUSION: Patients who test positive for a typical FEVR gene mutation reported more term births and had more severe disease by Yaguchi's classification. TSPAN12 was the most common genetic mutation in our population and had highly asymmetrical disease.

PURPOSE: To report outcomes of pediatric patients with combined hamartoma of the retina and the retina pigment epithelium followed up conservatively or after pars plana vitrectomy. METHODS: This retrospective multicenter study included 62 eyes of 59 pediatric patients with combined hamartoma of the retina and the retina pigment epithelium from 13 different international centers with an average age of 7.7 ± 4.7 (0.3-17) years at the time of the diagnosis and having undergone pars plana vitrectomy or followed conservatively. At baseline and each visit, visual acuity values, optical coherence tomography for features and central foveal thickness, and tumor location were noted. Lesions were called as Zone 1, if it involves the macular and peripapillary areas, and the others were called as Zone 2 lesions. RESULTS: Twenty-one eyes of 20 patients in the intervention group and 41 eyes of 39 patients in the conservative group were followed for a mean of 36.2 ± 40.4 (6-182) months. Best-corrected visual acuity improved in 11 (68.8%) of 16 eyes in the intervention group and 4 (12.9%) of 31 eyes in the conservative group ( P < 0.001). The mean central foveal thickness decreased from 602.0 ± 164.9 µ m to 451.2 ± 184.3 µ m in the intervention group, while it increased from 709.5 ± 344.2 µ m to 791.0 ± 452.1 µ m in Zone 1 eyes of the conservative group. Posterior location of tumor, irregular configuration of the foveal contour and ellipsoid Zone defect in optical coherence tomography, subretinal exudate and prominent vascular tortuosity were associated with poor visual acuity. CONCLUSION: Vitreoretinal surgery is safe and effective in improving vision and reducing retinal distortion in Zone 1 combined hamartoma of the retina and the retina pigment epithelium in children.

This study aims to investigate the outcomes and risk factors associated with poor vision (vision less than counting fingers, 2.0 logMAR, Snellen vision 20/2000) in patients with posterior or combined persistent fetal vasculature (PFV), with or without surgery. We retrospectively reviewed the medical records of patients who were diagnosed with PFV from January 2008 to April 2021. We included 51 eyes of 44 patients who presented with PFV, of which 38 eyes underwent surgical correction (pars plicata/plana vitrectomy, with or without lensectomy, and intraocular lens implantation) at the median age of 6.0 months (range: 0.7 to 82.0). The mean follow-up was 68.8 months ± 38.0 months. The axial length change in the eyes undergoing surgery was significantly higher than the eyes without surgery (p = 0.025). Initial anterior chamber collapse and retinal detachment were associated with poor vision (p = 0.006 and p = 0.002, respectively). In addition, 37% of eyes with posterior or combined PFV had vision better than counting fingers. Surgery for eyes with PFV could result in better eye growth. Visual outcomes remained poor and were associated with the level of macular abnormality. Initial anterior chamber collapse and retinal detachment at presentation were the risk factors for poor visual outcomes. Vitrectomy for selected PFV eyes is valuable and associated with a better cosmetic outcome (better eye growth).

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.

PURPOSE: To evaluate the 2-year efficacy and safety of micropulse transscleral cyclophotocoagulation (MP-TSCPC) in Taiwanese patients with glaucoma. METHODS: We included the patients who received standardized MP-TSCPC with follow-up examinations on a regular basis for 24 months. Treatment success was defined as the attainment of a postoperative intraocular pressure (IOP) between 6 and 21 mmHg or a ≥ 20% reduction in IOP from baseline without an increase in glaucoma medications. RESULTS: A total of 60 eyes from 56 patients who underwent MP-TSCPC for refractory glaucoma were included. The median age at MP-TSCPC intervention was 58.9 ± 12.4 years. The percentage of treatment success was 88.3% at 3 months, 83.3% at 6 months, 78.3% at 12 months, and 75.0% at 24 months. The mean baseline IOP prior to MP-TSCPC was 34 ± 11.9 mmHg (range 14-56 mmHg). The mean postoperative IOP decreased to 20.9 ± 10.0 mmHg, 18.0 ± 7.8 mmHg, 17.5 ± 6.4 mmHg, and 18.2 ± 7.1 mmHg after 3 months, 6 months, 12 months, and 24 months, respectively, in successful cases. The mean number of glaucoma medications at baseline was 3.8 ± 0.2, and the mean numbers of glaucoma medications at postoperative months 3, 6, 12, and 24 were 2.6 ± 0.7, 2.8 ± 0.6, 2.5 ± 1.4 and 2.6 ± 1.4, respectively, in successful cases. Younger age and prior CW-TSCPC significantly contributed to surgical failure in the multivariate model. Complications after MP-TSCPC included mild anterior chamber inflammation, conjunctival hemorrhage, hypotony, and mydriasis, and all subsided after treatment. None of the eyes developed vitreous hemorrhage, cystoid macular edema, or phthisis bulbi in the late postoperative period. CONCLUSIONS: This study demonstrated that younger age and prior CW-TSCPC were risk factors for MP-TSCPC failure within 2 years. MP-TSCPC might be safe and effective for refractory glaucoma patients with maximal antiglaucoma medications.

PURPOSE: To compare between oral and intravenous (IV) ultrawide-field fluorescein angiography in pediatric patients with a history of prematurity of retinopathy or prematurity. METHODS: Pediatric patients (<18 year old; n = 107 patients) who underwent ultrawide-field fluorescein angiography for retinopathy of prematurity were categorized into oral and IV fluorescein angiography (FA) groups. Quality of FA images was graded on the order of retinal vessels visible. Reported outcomes were proportions of graded FA images, peak fluorescein intensity, and the time to first dye appearance and to reach peak fluorescence. RESULTS: Image quality analysis revealed that 91.5% of IV FA images had excellent image quality compared with only 55.6% of oral FA images (P < 0.01). There were still 83.3% of oral-contrast images with good or excellent image quality. The average time required for first dye appearance and peak fluorescence were significantly shorter in the IV FA group than in the oral FA group (P < 0.01). Peak intensity was greater in the IV group (141.41 ± 29.09) than in the oral group (111.25 ± 45.68; P < 0.01). Adverse reaction rates were similar between the two groups (P = 0.22). CONCLUSION: Ultrawide-field fluorescein angiography provides excellent-quality imaging of the retina in the pediatric population. Overall, oral FA is still an effective and useful alternative to IV FA in children with prematurity history.

PURPOSE: To analyze the clinical characteristics, surgical outcomes, and risk factors associated with visual outcomes in patients with abusive head trauma (AHT). METHODS: We retrospectively reviewed surgical outcomes of patients with AHT who underwent vitrectomy from 2001 to 2019. The patients' demographics, comprehensive preoperative and postoperative ocular findings, surgical treatments, visual outcomes, and postoperative complications in the medical records were reviewed. Univariable and multivariable analyses were performed to identify the prognostic factors associated with visual outcomes. RESULTS: Fourteen children (18 eyes) diagnosed with AHT who underwent vitrectomy were evaluated. The most common surgical indication was vitreous hemorrhage (n = 6, 33%). Retinal attachment at the final visit was noted in 17 eyes (94%). Thirteen eyes (72%) had a best-corrected visual acuity less than 20/200 after vitrectomy. In the multivariable analysis, optic nerve atrophy (n = 9, 50%) was significantly associated with a poor visual prognosis (final best-corrected visual acuity worse than 20/200) after vitrectomy in children with AHT (95% confidence interval, 1.041-517.963, P = 0.0471). CONCLUSION: The general visual prognosis was poor for patients with AHT needing vitrectomy, although a high rate of retinal attachment was observed.

BACKGROUNDS: Branch retinal vein occlusion (BRVO) is one of the most important causes of visual loss in retinal vascular diseases. The aim of this study is to predict the treatment response of anti-vascular endothelial growth factor (anti-VEGF) therapy in BRVO using semi-automated quantified fluorescein angiography (FA) features. METHODS: This retrospective case-control study enrolled patients with BRVO who are receiving anti-VEGF therapy and have been followed up for > 1 year. Those receiving < 5 anti-VEGF injections in the first year were classified as the responsive group, while those receiving ≥5 injections were the refractory group. The FA images were subjected to semi-automated pre-processing. Fluorescein leakages at the 5-min image were represented by mean gray value over parafoveal and perifoveal regions. FA leakages and central retinal thickness (CRT) on optical coherence tomography (OCT) were used for predicting the treatment response and compared using area under receiver operating characteristic curve (AUC). RESULTS: Eighty-nine patients (56 males, 33 females, mean age 62.5 ± 10.9 years) with BRVO were enrolled. Of the 89 eyes, 47 (53%) were in the responsive group and 42 (47%) were in the refractory group. The refractory group had a significantly higher number of anti-VEGF injections in the first year (5.9 ± 1.6 versus 2.4 ± 1.2, p < 0.001) when compared with that of the responsive group. It had thicker pre-treatment CRT (p = 0.011), post-treatment best CRT (p < 0.001) and CRT at 1-year (p < 0.001). It also had a higher mean gray value over the parafoveal (p < 0.001) and the perifoveal (p < 0.001) regions. The mean gray value over perifoveal (AUC 0.846) and parafovel (AUC 0.818) had significantly larger AUC than that of the pre-treatment OCT (AUC 0.653; p = 0.005 and p = 0.016, respectively) when predicting treatment response. CONCLUSION: The refractory group had a more severe fluorescein leakage over the parafoveal and the perifoveal regions than the responsive group had. Semi-automated quantified FA leakage can be used as a biomarker for the prediction of anti-VEGF treatment response in macular edema due to BRVO.

The management of neovascular age-related macular degeneration (nAMD) has taken a major stride forward with the advent of anti-VEGF agents. The treat-and-extend (T&E) approach is a refined management strategy, tailoring to the individual patient's disease course and treatment outcome. To provide guidance to implementing anti-VEGF T&E regimens for nAMD in resource-limited health care systems, an advisory board was held to discuss and generate expert consensus, based on local and international guidelines, current evidence, as well as local experience and reimbursement policies. In the experts' opinion, treatment of nAMD should aim to maximize and maintain visual acuity benefits while minimizing treatment burden. Based on current evidence, treatment could be initiated with 3 consecutive monthly injections. After the initial period, treatment interval may be extended by 2 or 4 weeks each time for the qualified patients (i.e. no BCVA loss ≥5 ETDRS letters and dry retina), and a maximum interval of 16 weeks is permitted. For patients meeting the shortening criteria (i.e. any increased fluid with BCVA loss ≥5 ETDRS letters, or presence of new macular hemorrhage or new neovascularization), the treatment interval should be reduced by 2 or 4 weeks each time, with a minimal interval of 4 weeks. Discontinuation of anti-VEGF may be considered for those who have received 2-3 consecutive injections spaced 16 weeks apart and present with stable disease. For these individuals, regular monitoring (e.g. 3-4 months) is recommended and monthly injections should be reinstated upon signs of disease recurrence.

INTRODUCTION: The aim of this study was to investigate the risk of mood disorders in patients who experienced retinal detachment (RD) by using the National Health Insurance Research Database in Taiwan. METHODS: Participants with a diagnosis of RD were regarded as the study group, and an age- and sex-matched group without a diagnosis of RD served as the control group. The outcomes related to mood disorders after RD included: (1) psychiatric outpatient department visits; (2) behavioural therapy; (3) sleep or anxiety-related disorders; and (4) major depressive disorder (MDD). RESULTS: A total of 4,129 participants diagnosed with RD and 16,516 non-RD individuals were enrolled in the study. There were no significant differences in the four mood disorder-related outcomes between the study and control groups. However, the patients with recurrent RD who received more than two treatments and female patients with RD who needed surgical treatment showed a higher probability of developing MDD than did the non-RD subjects (incidence rate: 0.96 vs. 0.36; adjusted hazard ratio [aHR]: 2.382, 95% confidence interval [CI]: 1.032-5.496, log-rank p = 0.0325; and aHR: 6.895, 95% CI: 1.659-28.656, log-rank p = 0.0060, respectively). CONCLUSION: Patients with recurrent RD and multiple surgeries and females with RD who needed surgical treatment were at greater risk for developing MDD.
