RESUMEN
BACKGROUND: To assess rhegmatogenous retinal detachment (RRD) surgery trends and training among young ophthalmologists (YOs, vitreoretinal fellows or attendings/consultants with ≤10 years of independent practice) and the impact of the COVID-19 pandemic. METHODS: An anonymous online survey was completed by 117 YOs in the Asia-Pacific regarding their RRD surgery experiences in 2021-2022. RESULTS: To achieve a 90% probability of surgical competency, 91 vitrectomy and 34 scleral buckling (SB) completions during fellowship were needed. In total, 49 (41.9%) YOs had fellowship affected by COVID-19. In the COVID versus pre-COVID era, however, the volume of SB completions per fellowship year decreased significantly (median [IQR] 3.3 [1.5, 9] vs. 13 [6.5, 23]; p < 0.001) and was lower than the required volume to achieve competency. YOs were less confident in conducting SB versus vitrectomy (3.5 ± 1.1 vs. 4.2 ± 0.8, p < 0.001), and they reported a decrease in the proportion of SB (-3.1%, p = 0.047) and an increase in the proportion of vitrectomy (+4.8%, p < 0.001) after the pandemic outbreak. Apart from RRD clinical characteristics, surgical confidence is among the main factors that affect surgical method decisions. During the pandemic, more YOs may have avoided SB due to the need for general anaesthesia, leading to longer surgical time and risk of viral transmission during intubation/extubation. CONCLUSIONS: SB surgical exposure is suboptimal in most fellowship programs in the 11 Asia-Pacific countries/regions we surveyed and further declined during the COVID-19 pandemic. YOs are less confident in performing SB, leading to a trend toward primary vitrectomy since the COVID-19 outbreak.

BACKGROUND: To evaluate anatomical and functional outcomes of patients with large submacular hemorrhage (SMH) who treated by pars plana vitrectomy (PPV) in combination with subretinal tissue plasminogen activator (TPA) injection, intraocular gas tamponade, and with additional post-operative interventions. METHODS: Medical records of 9 patients who presented with large SMH secondary to age-related macular degeneration (AMD) and underwent PPV, subretinal TPA injection, and gas tamponade at Chiang Mai university hospital between January 2012 and January 2020 were reviewed. Collected data included preoperative visual acuity (VA), SMH extent and duration, intraoperation and post-operation complications, post-operative anatomical and VA responses, and the need for administer post-operation additional treatments. RESULTS: Overall, five patients were male and four patients were female with a mean (SD) age of 66.9 (7.7) years and a mean (SD) follow-up of 21.1 (16.1) months. A mean (SD) duration of SMH was 15.1 (10.9) days with a mean (SD) extent of SMH was 6.2 (3.4) disc diameters. At 1-month post-operation, complete SMH displacement was noted in eight (88.9%) patients. The mean (SD) VA significantly improved from LogMAR 1.9 (0.4) to 1.1 (0.4), (P = 0.004). During follow-up, eight patients (88.9%) were given additional therapy (anti-vascular endothelial growth factor (anti-VEGF) monotherapy, photodynamic therapy, or in combination). At final follow-up, a mean (SD) LogMAR VA of 0.9 (0.4) was significantly improved compared to baseline (P = 0.004). For intra- and post-operation complications, none developed intraoperative retinal break and retinal detachment. CONCLUSIONS: Vitrectomy with subretinal TPA injection, intraocular gas tamponade, and additional post-operation treatments provide benefit for anatomical and visual outcomes for patients with large SMH. It may consider as one of effective treatment in this group of patients.

INTRODUCTION: The study aimed to determine a reference database of the thickness and intraocular thickness asymmetry of total retina, retinal nerve fiber layer (RNFL), ganglion cell layer (GCL), and inner plexiform layer (IPL) in healthy Thai subjects measured by the Spectralis spectral-domain optical coherence tomography. METHODS: This cross-sectional study recruited the healthy subjects age ≥18 years, having spherical refraction within ±6 diopters and cylindrical refraction ±3 diopters, from a hospital's personnel and the people visiting the ophthalmology department. Only 1 eye of each subject was randomly selected for an analysis. Macular images were obtained using posterior pole thickness scan protocol over a 24° × 24° area at the center of the fovea. The automated retinal thickness segmentation values of total retina and three inner retinal layers were calculated for the mean and the mean intraocular thickness difference between superior and inferior retinal hemispheres. The influence of age, gender, and axial length on thickness and thickness asymmetry of individualized retinal layer was evaluated. RESULTS: 252 subjects were included in study with a mean (SD) age of 46.7 (15.8) years, and 120 (47.6%) were males. According to the Early Treatment Diabetic Retinopathy Study map, the inner ring area was the thickest location of the total retina (range; 326.0-341.5 µm), GCL (range; 47.7-52.7 µm), and IPL (range; 39.9-42.1 µm), whereas the thickest location of RNFL was at the outer ring area (range; 18.8-47.5 µm). For posterior pole intraocular thickness asymmetry, the greatest mean ± SD difference was observed for total retina (9.0 ± 2.2 µm), followed by RNFL (9.9 ± 3.2 µm) and GCL (2.7 ± 0.6 µm), and the lowest mean difference was noted for IPL (2.4 ± 0.5 µm). The thickness and thickness asymmetry of each retinal layer were variably influenced by age, gender, and axial length; however, these factors had a minimal influence on the thickness asymmetry maps of GCL and RNFL. CONCLUSION: The reference database of the macular thickness and thickness asymmetry from this study would be beneficial in determining physiologic variations of the OCT parameters in the healthy Thai population.

PURPOSE: To evaluate the visual outcome and macular anatomic structures on spectral-domain optical coherence tomography (SD-OCT) of patients with epiretinal membrane (ERM) foveoschisis who underwent vitrectomy. METHODS: A retrospective cohort, interventional, case series. PARTICIPANTS: Fourteen patients (14 eyes) with central vision loss from an ERM foveoschisis underwent vitrectomy at Chiang Mai University Hospital from 2017 to 2018 and had a follow-up period of 12 months. INTERVENTIONS: The 23G vitrectomy with ERM and internal limiting membrane (ILM) peeling was performed by a single surgeon. MAIN OUTCOMES: Best-corrected visual acuity (BCVA) and anatomic appearance on SD-OCT were assessed at the time of preoperative evaluations and post-operative follow-ups at 1, 3, 6, and 12 months. RESULTS: Fourteen patients with a mean (SD) age of 67.9 (7.9) years and a mean (SD) visual acuity (VA) of 0.6 (0.1) LogMAR units were included in this study. Significant VA improvements were observed at the 3-month (0.43 (0.14) LogMAR unit), 6-month (0.45 (0.16) LogMAR unit) and 12-month (0.37 (0.21) LogMAR unit) post-operative visits compared to baseline, all with P-values < 0.001. At month 12, there were vision improvements of ≥3 lines in 8 (57.2%) patients, vision improvements of 1 or 2 lines in 2 (14.3%) patients, vision remained at the same line of pre-operation in 3 (21.4%) patients, and vision decreased by 1 line in 1 (7.1%) patient. Regarding the anatomical outcomes, 13 (92.9%) patients achieved anatomical foveal restoration, while one had persistent intraretinal schisis at the 12-month follow-up. The median time to achieve a foveal restoration was 3 months. No significant visual impairments were observed post-operatively. CONCLUSION: In patients with central vision loss from ERM foveoschisis, vitrectomy with ILM stripping tended to improve both visual and anatomical outcomes.

INTRODUCTION: The objective of this study was to explore visual and anatomical outcomes in patients who underwent intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection for visual impairment from center-involved diabetic macular edema (CI-DME) in clinical practice. METHODS: Medical records of consecutive CI-DME patients who initiated treatment with intravitreal bevacizumab injection between January 2012 and December 2016 and were followed for at least 12 months were retrospectively reviewed. Visual and anatomical changes after treatment over a 36-month period were evaluated. RESULTS: There were 286 patients (423 eyes) with a mean (standard deviation, SD) age of 56.8 (8.5) years included in this study. One hundred and forty-six (51%) patients were female, and 137 (47.9%) patients received bilateral eye treatment. Mean (SD) presenting visual acuity (VA) of overall eyes was 50.2 (19.6) letter scores. Stratified by baseline vision, eyes with initial VA worse than 20/40 achieved a statistically significant VA improvement, compared to baseline, by +8.4, +6.9, and +5.4 letters at 12, 24, and 36 months, respectively, with all p values <0.001. However, when initial VA was 20/40 and better, a non-statistically significant change in mean VA by +2.0, -3.5, and -3.6 letters were noted at the same time point (p value between 0.078 and 0.273). Unlike visual changes, a statistically significant decline in central subfield thickness compared to baseline was noted at the end of months 12, 24, and 36 in both initial VA subgroups (all p values <0.001). Nevertheless, even though the median number of given injections considerably decreased from 6 in the first 12 months to 2 in the second 12-month period and 1 in the final 12-month interval, required ophthalmic clinic visits decreased in frequency with median numbers of 10, 7, and 6 appointments in each consecutive 12-month duration. CONCLUSION: This study supports the benefits of practical intravitreal anti-VEGF utilization to manage CI-DME in real-world settings. The improvement of vision in eyes presenting with poor baseline VA and maintenance of vision in eyes with better baseline VA were demonstrated through the 3-year review of each case. However, the burden of frequent monitoring warrants further evaluation of long-term compliance and efficacy.

PURPOSE: To investigate efficacy and safety of repeated dexamethasone (DEX) implants over 24 months, in diabetic macular edema (DME) eyes that were treatment naive compared with eyes refractory to anti-vascular endothelial growth factor treatment, in a real-life environment. METHODS: This multicenter international retrospective study assessed best-corrected visual acuity and central subfield thickness (CST) of naive and refractory eyes to anti-vascular endothelial growth factor injections treated with dexamethasone implants. Safety data (intraocular pressure rise and cataract surgery) were recorded. RESULTS: A total of 130 eyes from 125 patients were included. Baseline best-corrected visual acuity and CST were similar for naive (n = 71) and refractory eyes (n = 59). Both groups improved significantly in vision after 24 months (P < 0.001). However, naive eyes gained statistically significantly more vision than refractory eyes (+11.3 ± 10.0 vs. 7.3 ± 2.7 letters, P = 0.01) and were more likely to gain ≥10 letters (OR 3.31, 95% CI 1.19-9.24, P = 0.02). At 6, 12, and 24 months, CST was significantly decreased compared with baseline in both naive and refractory eyes; however, CST was higher in refractory eyes than in naive eyes (CST 279 ± 61 vs. 313 ± 125 µm, P = 0.10). CONCLUSION: Over a follow-up of 24 months, vision improved in diabetic macular edema eyes after treatment with dexamethasone implants, both in eyes that were treatment naive and eyes refractory to anti-vascular endothelial growth factor treatment; however, improvement was greater in naive eyes.

PURPOSE: The main objective of this study was to investigate the microbiological spectrum of endophthalmitis after anti-VEGF injections and to compare streptococcal with non-streptococcus-associated cases with regard to baseline characteristics and injection procedure. METHODS: Retrospective, international multicenter study of patients with culture-positive endophthalmitis after intravitreal anti-VEGF injection at 17 different retina referral centers. RESULTS: Eighty-three cases with 87 identified pathogens were included. Coagulase-negative staphylococci (59%) and viridans streptococci (15%) were the most frequent pathogens found. The use of postoperative antibiotics and performance of injections in an operating room setting significantly reduced the rate of streptococcus-induced endophthalmitis cases (p = 0.01 for both). CONCLUSION: We found a statistically significant lower rate of postinjectional local antibiotic therapy and operating room-based procedures among the streptococcus-induced cases compared to cases caused by other organisms.

PURPOSE: We present the multifocal electroretinogram (mfERG) with a 7-hexagon array as an objective test of macular function that can be recorded in 14 s. We provide normal values and investigate its reproducibility and validity. METHODS: Healthy participants underwent mfERG testing according to International Society for Clinical Electrophysiology of Vision (ISCEV) standards using the Espion Profile/D310 multifocal ERG system (Diagnosys, LLC, Lowell, MA, USA). One standard recording of a 61-hexagon array and 2 repeated recordings of a custom 7-hexagon array were obtained. RESULTS: A total of 13 subjects (mean age 46.9 years) were included. The median response densities were 12.5 nV/deg2 in the center and 5.2 nV/deg2 in the periphery. Intereye correlations were strong in both the center (ρCenter = 0.821; p < 0.0001) and the periphery (ρPeriphery = 0.862; p < 0.0001). Intraeye correlations were even stronger: ρCenter = 0.904 with p < 0.0001 and ρPeriphery = 0.955 with p < 0.0001. Bland-Altman plots demonstrated an acceptable retest mean difference in both the center and periphery, and narrow limits of agreement. We found strong correlations of the center (ρCenter = 0.826; p < 0.0001) and periphery (ρPeriphery = 0.848; p < 0.0001), with recordings obtained by the 61-hexagon method. CONCLUSIONS: The 7-hexagon mfERG provides reproducible results in agreement with results obtained according to the ISCEV standard.

PURPOSE OF REVIEW: Given the increasing prevalence of geographic atrophy from age-related macular degeneration as the number of individuals over 85 increases throughout the world, as well as the recent increase in potential treatments to slow growth of geographic atrophy, this article discusses recent findings regarding retinal imaging of geographic atrophy to detect its presence or expansion over time. RECENT FINDINGS: During the review period, the COMPLETE (Systemic complement inhibition with eculizumab for geographic atrophy in age-related macular degeneration) and the GATE (Randomized trial to evaluate tandospirone in geographic atrophy secondary to age-related macular degeneration) studies, respectively, reported no beneficial effects of intravenous eculizumab or tandospirone eye drops, respectively, identified on the growth of geographic atrophy. Several imaging and visual function studies have evaluated the role of various techniques using fundus autofluorescence, optical coherence tomography, microperimetry, or other investigator-initiated tools to assess geographic atrophy growth or progression over time, although the ideal imaging for geographic atrophy remains unknown. Some predictive factors for geographic atrophy growth recently suggested include genetic features, geographic atrophy characteristics in the fellow eye, or the presence of outer retinal tubulation on optical coherence tomography. SUMMARY: Quantification of geographic atrophy is important for evaluating growth of geographic atrophy. Numerous new imaging techniques of geographic atrophy beyond human grading of fundus photographs or fluorescein angiograms have emerged, but the ideal imaging for geographic atrophy has yet to be determined.

The aim of this study is to determine the associations between regional macular thickness and gender, age, axial length, and degree of myopia in young and middle-aged healthy myopic eyes. One hundred and seventy-one subjects with -0.5 diopters of myopia or worse underwent prospective macular thickness measurement by Spectralis spectral-domain optical coherence tomography. Subjects' mean age was 32.40 ± 8.25 years (range 18 to 49 years), with 45 % being male. The mean degree of myopia was -4.57 ± 3.52 diopters, with a mean axial length of 25.09 ± 1.67 mm. Multivariate regression analysis demonstrated significantly thicker central (mean 9.13 µm thicker) and inner subfields (mean 8.55 µm thicker) in males (P values were <0.001 and 0.002, respectively). In addition, in both genders, for each millimeter of increased axial length, the central subfield thickness increased by 2.11 µm, the inner subfield decreased by 2.25 µm, and the outer subfield decreased by 3.62 µm (P values were 0.010, <0.001, and <0.001, respectively). Factors including gender and axial length affect baseline regional macular thickness in young and middle-age myopic subjects. The central subfield and inner subfield were affected by both gender and axial length, while the outer subfield was affected only by axial length. The macular thickness of myopic subjects with macular disease should be interpreted in light of these factors.

PURPOSE: To assess the development of vision-threatening lesions at least 3.5 years after initiating anti-vascular endothelial growth factor (VEGF) for choroidal neovascularization (CNV) in eyes with age-related macular degeneration (AMD). DESIGN: Retrospective cohort study. PARTICIPANTS: A total of 75 patients (81 eyes) with CNV secondary to AMD who received intravitreous anti-VEGF treatment and were followed for at least 3.5 years after initiating treatment. METHODS: Retrospective record review of patients initiating anti-VEGF treatment between November 2005 and June 2008 at a university-based institution for whom at least 3.5 years of follow-up was available at the same institution. MAIN OUTCOME MEASURES: Predominantly hemorrhagic lesions or geographic atrophy (GA). RESULTS: Among 75 patients (81 eyes; 59% were women; median age, 78 years), mean follow-up was 4.9 years and at least 6 years for 40%. Median visual acuity (VA) was 20/80 (interquartile range [IQR], 20/50-20/100) initially, 20/63 (IQR, 20/40-20/160) at 2 years, 20/80 (IQR, 20/40-20/200) at 3.5 years, and 20/63 (IQR 20/32-20/200) at 6 years. Six eyes (7%) had predominantly hemorrhagic lesions initially, whereas this developed in an additional 3 eyes (4%, 95% confidence interval [CI], 1% to 10%) in 3.5 years and in 1 additional eye (1%, 95% CI, 0.03% to 7%) at more than 3.5 years of follow-up. Initially, GA within or overlapping the boundary of the entire CNV was present in 4 eyes (5%) and outside this boundary in 8 eyes (10%). Geographic atrophy enlarged in each eye over time. The only eyes that developed GA outside the CNV boundary were those that had GA outside the lesion at baseline. Additional atrophy within the boundary of CNV defined at baseline, termed "atrophic disciform scars," developed in 5 eyes (6%), all within 4 years of treatment initiation. CONCLUSIONS: Longer-term follow-up of neovascular AMD managed with anti-VEGF therapy suggests that predominantly hemorrhagic lesions may develop within 3.5 years of initiating therapy and more than 3.5 years after initiating therapy. In contrast, new areas of GA beyond the boundaries of the CNV lesion as defined at initiation of anti-VEGF therapy seem unlikely to develop if there is no GA outside of the CNV lesion initially.

OBJECTIVES: This study aimed to establish normative health utility data in Thai patients with diabetic retinopathy, wet age-related macular degeneration, and cataract; evaluate the sensitivity of different utility instruments to visual impairment; explore the relationship among these health utility values with the vision-specific quality of life (QoL); and assess the association of baseline characteristics and visual acuity level with health utility values and vision-specific QoL. METHODS: This multicenter cross-sectional survey included 309 patients from tertiary eye centers. We used health utility instruments (time trade-off [TTO], EuroQol five-dimension [EQ-5D-5L], and Health Utility Index 3 [HUI3]) and vision-specific QoL instrument (National Eye Institute Visual Function Questionnaire) for face-to-face interviews. Demographic data and Early Treatment Diabetic Retinopathy Study visual acuity were recorded during the participants ophthalmic visits. Univariable and multivariable mixed-effect models were used to evaluate factors associated with the utility scores. Health utility scores among each type of eye disease were compared. RESULTS: The overall mean utility values from the TTO, EQ-5D-5L, and HUI3 were 0.84 ± 0.25, 0.70 ± 0.19, and 0.68 ± 0.26, respectively. The health utility scores obtained from TTO and HUI3 showed a significant response to severe visual impairment or worse. Health utility scores from HUI3 (r = 0.54; P < .01) and EQ-5D-5L (r = 0.43; P < .01) displayed a moderate correlation with the National Eye Institute Visual Function Questionnaire score. There were no significant differences in health utility value among the 3 diseases upon adjusting for the visual acuity level and demographics. CONCLUSIONS: Visual acuity level has a greater impact on a patient's QoL than the type of eye disease. HUI3 and EQ-5D-5L and TTO are suitable for measuring health utility in leading causes of blindness.
RESUMEN
Giant retinal tear-associated rhegmatogenous retinal detachment (GRT-RRD) presents a significant surgical challenge. Trauma stands out as one of the risk factors. This retrospective case series aims to assess the outcomes of GRT-RRD patients treated with pars plana vitrectomy (PPV), distinguishing between non-trauma and blunt ocular trauma cases. The medical records and relevant retinal imaging of 60 GRT-RRD patients undergoing PPV and followed with a mean (SD) of 21.2 (13.4) months were reviewed (47 were non-trauma-related and 13 were trauma-related). Both the non-trauma and trauma groups exhibited comparable distribution of proliferative vitreoretinopathy grade (P = 0.067). Following the primary operation, there was no statistically significant difference in the proportion of patients achieving single surgery anatomical success between the non-trauma group (27/47 patients, 57.5%) and the trauma-related group (9/13 patients, 69.2%) (P = 0.534). At the final follow-up, 17 patients remained tamponade with silicone oil. Among the remaining 43 patients, 33/34 patients (97.1%) in the non-trauma group and 9/9 patients (100%) in the non-trauma group (P = 0.661) achieved comparable final surgical anatomical success. Additionally the final vision was comparable between the two trauma categories (Snellen equivalent of 20/125 for the non-trauma group and 20/200 for the trauma group, P = 0.331). In multivariable regression, no significant factors related to primary reattachment rate or final vision were identified. Non-penetrating ocular trauma did not emerge as a significant risk factor for recurrent detachment post-surgery. This study supports that PPV outcomes in GRT-RRD patients are unaffected by the ocular trauma association and reports the effectiveness of PPV in managing these patients.

Purpose: To describe the rationale and design of the VOYAGER (NCT05476926) study, which aims to investigate the safety and effectiveness of faricimab and the Port Delivery System with ranibizumab (PDS) for neovascular age-related macular degeneration (nAMD) or diabetic macular edema (DME) in clinical practice. VOYAGER also aims to understand drivers of clinical practice treatment outcomes by gaining novel insight into the intersection of treatment regimens, decisions, anatomic outcomes, and vision. Design: Primary data collection, noninterventional, prospective, multinational, multicenter clinical practice study. Participants: At least 5000 patients initiating/continuing faricimab or PDS for nAMD/DME (500 sites, 31 countries). Methods: Management will be per usual care, with no mandated scheduled visits/imaging protocol requirements. Using robust methodologies, relevant clinical and ophthalmic data, including visual acuity (VA), and data on treatment clinical setting/regimens/philosophies, presence of anatomic features, and safety events will be collected. Routinely collected fundus images will be uploaded to the proprietary Imaging Platform for analysis. An innovative investigator interface will graphically display the patient treatment journey with the aim of optimizing treatment decisions. Main Outcome Measures: Primary end point: VA change from baseline at 12 months per study cohort (faricimab in nAMD and in DME, PDS in nAMD). Secondary end points: VA change over time and per treatment regimens (fixed, treat-and-extend, pro re nata, and other) and number. Exploratory end points: VA change in relation to presence/location of anatomic features that impact vision (fluid, central subfield thickness, fibrosis, atrophy, subretinal hyperreflective material, diabetic retinopathy severity, and disorganization of retinal inner layers) and per treatment regimen/philosophies. The impact of regional and practice differences on outcomes will be assessed as will safety. Results: Recruitment commenced in November 2022 and will continue until late 2027, allowing for up to 5 years follow-up. Exploratory interim analyses are planned annually. Conclusions: VOYAGER is an innovative study of retinal diseases that will assess the effectiveness and safety of faricimab and PDS in nAMD and DME and identify clinician- and disease-related factors driving treatment outcomes in clinical practices globally to help optimize vision outcomes.

RESUMEN
PURPOSE: To determine the characteristics, primary sources, pathogens, risk factors, and visual outcomes in patients with endogenous endophthalmitis (EE). METHODS: We performed a retrospective cohort study of 61 consecutive patients with EE (74 affected eyes) and reported on prevalence, clinical courses, prognostic factors and visual outcomes. RESULTS: Prevalence of EE was 5% of all patients with endophthalmitis. Among culture-positive cases (89%), Gram-positive species dominating (69%) followed by Gram-negative with 22% and fungal species with 9%. Regarding to visual outcomes, the mean visual acuity (VA, ETDRS letters) at baseline, 3-months, 6-months and 1-year follow-up was 0.85, 9, 8 and 9, respectively. Initial VA of hand movement or better (P 0.007) and bilateral infection (P 0.004) were associated with better visual outcome. CONCLUSION: The prognosis for EE remained poor despite aggressive and immediate treatment. The high suspicion, early diagnosis and prompt treatment are important factors that might lead to the better outcome.

Purpose: To determine characteristics and factors associated with no vision survival (included no light perception, enucleation, and evisceration) following open globe injury (OGI) and to correlate the proportion of final vision to predictive values of ocular trauma score (OTS). Patients and Methods: The medical records of consecutive patients diagnosed as OGI between January 2015 and December 2020 were retrospectively reviewed. Data collected included demographics, mechanisms and modes of injuries, ophthalmic presentations, managements, and visual outcomes at the final visit. Results: Three hundred and seventy-one patients with a mean (standard deviation, SD) age of 44.0 (17.4) years were included. Male with workplace injury was the most frequent scenario. High-velocity metallic objects were the predominant causative materials. Following treatments, fifty-six eyes (14.9%) obtained no vision survival. Factors associated with no vision survival following OGI were low presenting vision, globe perforation, larger wound, presence of relative afferent pupillary defect, retinal detachment, and vitreous hemorrhage. Compared to OTS predictive values, eyes in OTS categories 1 and 2 had a lower proportion of no vision survival. Conclusion: This study identified the importance of workplace injuries. Overall, there were comparable final visions between OTS and this study. However, a reduced proportion of no vision survival among severely injured eyes signifies the challenges of OGI management.
RESUMEN
Introduction: Retained intraocular foreign body (IOFB) remains an important cause of acquired visual impairment. The visual prognosis following treatments for eyes with retained IOFB was observed to be distinct from other mechanisms of open globe injury due to the specific nature and associated circumstances. This study evaluated the risk behaviors, visual results, and predictive values of Ocular Trauma Score (OTS) in determining visual outcomes in patients with IOFB that were not related to terrorism. Methods: Medical records of patients who underwent surgical interventions between January 2015 and December 2020 were retrospectively reviewed. Results: A total of one hundred and sixty-one patients (162 eyes) were recruited. The patients had a mean (standard deviation) age of 47.6 (14.0) years with working male predominance (93.2%). The majority of patients were injured by activities related to grass trimming (63.4%) and metallic objects were the main materials causing injuries (75.7%). Following treatments, the proportion of eyes having vision worse than 20/400 decreased from 126 eyes (77.8%) to 55 eyes (33.9%) at final visit. Ocular trauma score (OTS) had a high potential prediction for final vision in eyes in OTS categories 4 and 5. However, the discordance of final visual acuity distribution was observed in some subgroups of eyes in OTS categories 1 to 3. Conclusion: This study highlights the significance of IOFB related eye injuries in a tertiary care setting. Decision making on treatments should be carefully considered, particularly in eyes in lower OTS categories, in light of a rise in the proportion of patients who experience improved vision after IOFB removal.
RESUMEN
There have been recent advances in basic research and clinical studies in polypoidal choroidal vasculopathy (PCV). A recent, large-scale, population-based study found systemic factors, such as male gender and smoking, were associated with PCV, and a recent systematic review reported plasma C-reactive protein, a systemic biomarker, was associated with PCV. Growing evidence points to an association between pachydrusen, recently proposed extracellular deposits associated with the thick choroid, and the risk of development of PCV. Many recent studies on diagnosis of PCV have focused on applying criteria from noninvasive multimodal retinal imaging without requirement of indocyanine green angiography. There have been attempts to develop deep learning models, a recent subset of artificial intelligence, for detecting PCV from different types of retinal imaging modality. Some of these deep learning models were found to have high performance when they were trained and tested on color retinal images with corresponding images from optical coherence tomography. The treatment of PCV is either a combination therapy using verteporfin photodynamic therapy and anti-vascular endothelial growth factor (VEGF), or anti-VEGF monotherapy, often used with a treat-and-extend regimen. New anti-VEGF agents may provide more durable treatment with similar efficacy, compared with existing anti-VEGF agents. It is not known if they can induce greater closure of polypoidal lesions, in which case, combination therapy may still be a mainstay. Recent evidence supports long-term follow-up of patients with PCV after treatment for early detection of recurrence, particularly in patients with incomplete closure of polypoidal lesions.

Objectives: To evaluate the associations between anatomical changes and visual outcomes in patients with idiopathic epiretinal membrane (ERM). Materials and Methods: We performed a prospective study of 130 consecutive idiopathic ERM patients and report their visual outcomes and the factors associated with visual outcome and anatomical changes. Results: Of 130 eyes of 130 patients, 87 eyes underwent surgery, while the remaining 43 eyes were observed. At 6-month follow-up, the best-corrected visual acuity (BCVA) increased in the whole population. Mean Early Treatment Diabetic Retinopathy Study letter score changed from 51 to 65 in the surgical group and from 67 to 68 in the non-surgical group. The surgical group had improvement in BCVA at all ERM stages and grades of disorganization of the retinal inner layers (DRIL) (p<0.01). In multivariable analysis of the surgical group, factors associated with BCVA of ETDRS 60 letters or more were no or mild DRIL and the absence of ellipsoid zone disruption at baseline (p=0.002 and p=0.034, respectively) and this statistically significant positive correlation was still maintained at 12-month follow-up. Conclusion: Baseline DRIL grade and presence of ellipsoid zone disruption were the most informative prognostic factors in patients with idiopathic ERMs. Patients with severe DRIL and/or advanced ERMs had improved vision after ERM removal.

PURPOSE: To understand timing of complete polypoidal regression on indocyanine green angiography (ICGA) after aflibercept injections for polypoidal choroidal vasculopathy (PCV). DESIGN: Multicenter prospective study. PARTICIPANTS: Adults with treatment-naïve PCV. METHODS: After institutional review board approval, participants were enrolled and followed up for 1 year, from Apr 1, 2016, through Dec 30, 2018, at 2 university-based centers in Thailand. Diagnosis of PCV was based on the Efficacy and Safety of Verteporfin Photodynamic Therapy in Combination with Ranibizumab or Alone versus Ranibizumab Monotherapy in Patients with Symptomatic Macular Polypoidal Choroidal Vasculopathy criteria. Eligible eyes received fixed-dose aflibercept injections (3 monthly then every 8 weeks), or monthly if fluid persisted on OCT. Photodynamic therapy (PDT) was administered when fluid persisted despite 6 consecutive injections. Indocyanine green angiography was performed at baseline and then every 8 weeks. The 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) was administered at baseline, 6 months, and 1 year. Two retina specialists reviewed posttreatment ICGA, categorized into: complete regression (complete disappearance of polypoidal lesions), partial regression (reduced in size or number), or no regression. Disagreements were resolved through open adjudication. MAIN OUTCOME MEASURES: Timing of complete regression over 1 year. RESULTS: Final analysis included 40 eyes (39 participants; 100% Thai, 59% women; mean age±standard deviation, 64 ± 8.3 years). At baseline, 90% had 5 or more polypoidal lesions. Ninety-five percent received aflibercept monotherapy, and 5% received rescue PDT per protocol. Polypoidal statuses at 1 year were 55% complete, 40% partial, and 5% no regression. Cumulative rates of complete regression at 2, 4, 6, and 12 months were 28%, 33%, 43%, and 55%. Of 22 eyes with complete regression at 1 year, complete regression was identified first at 2, 4, 6, 8, 10, 12 months in 50%, 9%, 18%, 5%, 9%, and 9%, respectively. Cumulative rates of complete regression among these eyes at 2, 6, and 12 months were 50%, 77%, and 100%, respectively. Median duration of complete regression was 3 months (interquartile range, 2-6 months). Median visual acuity improved from 20/125 (Snellen equivalent) to 20/50; median NEI VFQ-25 scores improved from 80 to 93 from baseline to 1 year. CONCLUSIONS: Complete polypoidal regression could occur as early as 2 months after aflibercept injections. Most PCV eyes with complete polypoidal regression at 1 year already showed complete regression within the first 6 months. These findings support consideration of aflibercept for PCV to achieve both anatomic and visual outcomes.
