RESUMEN
Introduction: Valsalva retinopathy can cause submacular hemorrhage (SMH), which may lead to visual disturbances. SMH can extend into the subinternal limiting membrane (ILM) and vitreous spaces, sometimes occurring concomitantly with full-thickness macular holes (FTMHs). Herein, we describe a case in which sub-ILM hemorrhage was removed without peeling the ILM of the central fovea, thus preserving the foveal ILM. Case Presentation: A 48-year-old female patient developed rapid-onset bilateral visual impairment due to SMH secondary to Valsalva retinopathy. The SMH predominantly consisted of sub-ILM hemorrhage. However, detailed observation was challenging due to the dense sub-ILM hemorrhage in the left eye. Initial best-corrected visual acuity (BCVA) in the right and left eyes were 1.2 and 0.03, respectively. Intravitreal tissue plasminogen activator (tPA) and sulfur hexafluoride (SF6) gas injections were initially administered to displace the SMH in the left eye; however, the SMH could not be successfully displaced. A vitrectomy was then performed. Intraoperatively, an ILM fissure beyond the foveal region was created using ILM forceps. The balanced salt solution was sprayed onto the ILM, and the sub-ILM hemorrhage was drained into the vitreous cavity from the ILM fissure. The surgery successfully displaced the sub-ILM hemorrhage while preserving the foveal ILM. No postoperative complications were observed. Visual acuity remained at 1.2 in the right eye and improved to 1.2 in the left eye 6 months postoperatively. Conclusion: Removing foveal sub-ILM hemorrhage without peeling the foveal ILM can be a viable treatment option to preserve the foveal ILM.
RESUMEN
PURPOSE: Psychological violence and harassment have been reported to be associated with mental health problems and turnover intention among nurses. Cyberbullying, a hidden form of harassment using information and communication technology, is attracting attention as a factor that threatens the mental health of nurses. This study aimed to add coping characteristics, social support, and workplace social capital to psychological violence, harassment, and cyberbullying in female nurses and determine their association with depression and turnover intention. PARTICIPANTS AND METHODS: An anonymous, self-administered questionnaire survey was conducted, targeting 2,158 female nurses working in four domestic hospitals, excluding those in management positions. The analysis included 1,151 nurses who responded (valid response rate: 53.3%). Multiple regression analysis was performed with depression and turnover intention as dependent variables and psychological violence and harassment, cyberbullying, the brief scales for coping profile (BSCP) and social support scale scores, and social capital (SC) as independent variables. RESULTS: Depression was positively correlated with psychological violence and harassment, cyberbullying, and the BSCP subscale "avoidance and suppression" and negatively correlated with the BSCP subscale "changing the point of view" and social support subscales "support from supervisors" and "support from co-workers." Turnover intention was positively correlated with psychological violence and harassment and the BSCP subscale "avoidance and suppression" and negatively correlated with the BSCP subscale "changing the point of view," social support subscale "support from supervisors," and vertical SC. DISCUSSION AND CONCLUSION: The results suggest that work environments should prevent psychological violence and harassment in nurses to promote a sense of security and eliminate mental health problems. Cyberbullying was inferred as a factor that could lead to mental health problems among nurses. Therefore, each nurse should raise their awareness of information literacy, besides attending more to their words and attitudes.
RESUMEN
PURPOSE: To investigate the impact of using digital assisted vitrectomy (DAV) for color enhancement in color channel and achromatization in color profile on the visibility of indocyanine green (ICG)-stained internal limiting membrane (ILM). STUDY DESIGN: Retrospective observational study. METHODS: Twenty eyes from 20 patients (7 men, 13 women) who underwent 27-gauge pars plana vitrectomy for epiretinal membrane removal were included. The presettings of five different imaging modes of the NGENUITY® 3D visualization system (Alcon laboratories, Inc.), were adjusted, and intraoperative images of ILM removal were captured under each presetting. The color contrast ratios (CCR) between the ICG-stained ILM area and peeled ILM area were compared across presettings objectively. Subjective visibility of ILM in each patient for different presettings was ranked using a Likert scale and evaluated by five examiners. Data on sex, age, preoperative and postoperative best-corrected visual acuity (BCVA), preoperative and postoperative intraocular pressure (IOP), and postoperative complications were analyzed. RESULTS: Compared to other presettings the best CCR was achieved by adjusting the color channel to enhance red and by modifying the color profile to create a monochrome image (P<0.01). The same presetting resulted in a highest subjective visibility (P<0.01). Mean preoperative BCVA and 6-month postoperative BCVA (logMAR) were 0.11±0.18 and 0.05±0.19, respectively (p=0.24). Mean preoperative IOP and 6-month postoperative IOP were 13.8±2.8 mmHg and 13.3±3.4 mmHg, respectively (p=0.51). No apparent intra- and post-operative complications were observed. CONCLUSION: Color enhancement and achromatization using DAV may offer potential advantages to enhance the visibility of ICG-stained ILM.

Currently, elderly care facilities that do not offer long-term care are not required to employ pharmacists, and duties such as the dispensing and distribution of medicines are entrusted to external pharmacies. Pharmacists seldom spend sufficient time at the facilities for elderly people requiring special care. Thus, in many cases, the pharmacists have insufficient knowledge of the residents' medication status, leading to their inability in determining whether the residents are receiving a suitable drug therapy. We previously documented various problems in the practices adopted by nursing staff (with negligible intervention by pharmacists) for assisting residents in taking their medications. In the present pilot study, we attempted to eliminate the use of potentially inappropriate medications by stationing a pharmacist at a nursing home for 24 h every week (3 d/week). We proactively collected information from nurses and other nursing staff and observed the residents' actual living conditions and medication use. As a result of this intervention, 56 prescriptions were changed. However, only two of these were changed exclusively based on the prescription information. Most prescriptions were able to change based on the information obtained by the pharmacist present at the facility. Therefore, pharmacists' presence at the facility (at least for a few hours) is necessary, as they can actively intervene and collaborate with other staff to prevent the use of potentially inappropriate medications.

PURPOSE: To investigate the incidence of intraocular inflammation (IOI) and its risk factors following intravitreal injections of brolucizumab for neovascular age-related macular degeneration in Japan. METHODS: A total of 1,351 Japanese consecutive patients with neovascular age-related macular degeneration who were treated with brolucizumab from May 2020 to May 2022 at 14 institutions were examined. The variables analyzed were the number of brolucizumab injections, time to onset of IOI, and risk factors. RESULTS: Intraocular inflammation developed in 152 eyes (11.3%). Retinal vasculitis and/or retinal occlusion occurred in 53 eyes (3.9%). Ninety-four patients received bilaterally, bilateral IOI occurred in five patients (5.3%). Sixteen eyes (1.2%) had irreversible visual acuity loss and nine eyes (0.67%) had visual loss of three lines or more due to retinal vasculitis and/or retinal occlusion. The cumulative IOI incidence was 4.5%, 10.3%, and 12.2% at 30, 180, and 365 days (1-year), respectively. History of IOI (including retinal vasculitis) and/or retinal occlusion (odds ratio [OR], 5.41; P = 0.0075) and female sex (OR, 1.99; P = 0.0004) were significantly associated with IOI onset. CONCLUSION: The 1-year cumulative incidence of IOI in Japanese neovascular age-related macular degeneration patients treated with brolucizumab was 12.2%. History of IOI (including retinal vasculitis) and/or retinal occlusion and female sex were significant risk factors.

This study investigated aniseikonia after reduced-fluence photodynamic therapy (RFPDT) for central serous chorioretinopathy (CSC). We examined 48 eyes of 48 patients (38 men; mean age, 49.2 ± 9.9 years) with CSC resolved after RFPDT. Horizontal and vertical aniseikonia were measured using the New Aniseikonia Test at baseline, 6 months, and 12 months after RFPDT. The maximum absolute value of the horizontal and vertical measurements indicated the aniseikonia score. The aniseikonia score was 2.2 ± 2.3 at 6 months and 2.2 ± 2.0 at 12 months after RFPDT, both of which improved significantly from the baseline score of 4.1 ± 2.9 (P < 0.05 and P < 0.01, respectively). The 12-month aniseikonia score significantly correlated with the baseline aniseikonia score (P = 0.047), outer nuclear thickness at baseline (P = 0.027) and 12 months after RFPDT (P = 0.014), baseline SRD area (P = 0.005), and ellipsoid zone disruption at 12 months after RFPDT (P = 0.021). In multivariate analysis, baseline serous retinal detachment (SRD) area (P = 0.034) was significantly associated with aniseikonia score at 12 months after RFPDT. Eyes with a larger SRD area might have higher aniseikonia scores even after SRD resolution following RFPDT.

To evaluate the functional and anatomical effects of switching to faricimab for patients with neovascular age-related macular degeneration (nAMD) refractory to intravitreal aflibercept, this retrospective study evaluated patients with nAMD who received intravitreal injections of aflibercept (IVA) every <8 weeks and were switched to faricimab. After switching, the patients were treated with a treatment and extended regimen that started with the interval just before switching and received at least three injections. We evaluated changes in the best-corrected visual acuity (BCVA), central retinal thickness (CRT), central choroidal thickness (CCT), treatment interval, and presence of retinal fluid. Overall, 55 eyes from 55 patients were examined. After three injections of faricimab, the BCVA and CCT did not change significantly. However, the CRT decreased significantly (p < 0.05), the injection interval was significantly extended (7.5 ± 2.3 vs. 5.9 ± 1.5 weeks, p < 0.01), and the rates of the presence of intraretinal fluid and subretinal fluid decreased significantly to 16.4% and 40% of eyes, respectively (both p < 0.01). An ocular adverse event (retinal pigment epithelium tear) developed in one eye. Switching to faricimab was effective for anatomic changes. It may be an additional treatment option for some eyes refractory to IVA.
RESUMEN
To report the usefulness of intraoperative real-time adjustment of intraocular lens (IOL) tilt during the intrascleral fixation with intraoperative optical coherence tomography (iOCT) as a clinical evaluation and investigate the factors contributing to IOL tilt using iOCT as an experimental evaluation. Retrospective cohort study and experimental research. As a clinical evaluation, the medical records of 43 eyes of 41 patients who underwent intrascleral IOL fixation combined with real-time iOCT observation were retrospectively reviewed. As an experimental evaluation, in order to investigate the factors contributing to IOL tilt, the four experiments were performed using iOCT. The mean IOL tilt angle (°) at the end of surgery and 3 months after surgery were 1.81 ± 1.15 and 2.10 ± 1.66, respectively (p = 0.46). No apparent intra- or postoperative complications occurred during the follow-up period. The experimental evaluation indicated that the IOL tilt was influenced by the insertion angle of the haptic in the vertical direction. The mean IOL tilt angle (°) was 1.94 ± 0.09, 4.67 ± 0.11, 8.90 ± 0.11, and 15.78 ± 0.85 when the insertion angle of the haptic was 0°, 10°, 27.5°, and 45° in the vertical direction, respectively (p < 0.01). Clinical and experimental IOL tilt assessment using iOCT is interactively useful for better quality surgery and better postoperative outcome.

PURPOSE: To compare the two-year outcome of half-time photodynamic therapy (htPDT) in chronic central serous chorioretinopathy (cCSC) with and without choroidal neovascularization (CNV). METHODS: In this retrospective study, we included 88 eyes of 88 patients with cCSC who underwent htPDT and were followed up for more than 24 months. Patients were divided into two groups with (21 eyes) or without (67 eyes) CNV before htPDT treatment. The best-corrected visual acuity (BCVA), central retinal thickness (CRT), subfoveal choroidal thickness (SCT), and the presence of subretinal fluid (SRF) were evaluated at baseline and at 1, 3, 6, 12, and 24 months after PDT. RESULTS: A significant intergroup difference was noted in terms of age (P = 0.038). Significant improvements in the BCVA and SCT were found at all time points in eyes without CNV but only at 24 months in eyes with CNV. CRT was significantly reduced in both groups at all time points. No significant intergroup differences were noted in terms of BCVA, SCT and CRT at all time points. There were significant differences in the rate of recurrent and persistent SRF between groups (22.4% (without CNV) vs. 52.4% (with CNV), P = 0.013, and 26.9% (without CNV) vs. 57.1% (with CNV), P = 0.017, respectively). The presence of CNV was significantly associated with the recurrence and persistence of SRF after initial PDT (P = 0.007 and 0.028, respectively). Logistic regression analyses showed that the baseline BCVA, and not the presence of CNV, was significantly associated with BCVA at 24 months after initial PDT (P < 0.01). CONCLUSIONS: A htPDT for cCSC was less effective in eyes with CNV than in those without CNV regarding the recurrence and persistence of SRF. Additional treatment might be required in eyes with CNV during 24-month follow-up periods.

The appropriate surgical technique to improve the closure rate of perioperative full-thickness macular hole (FTMH) secondary to submacular hemorrhage (SMH) with sub-internal limiting membrane (ILM) hemorrhage caused by retinal arterial macroaneurysm (RAM) rupture remains an unsolved clinical problem. Several ILM transplantation techniques have been attempted, but these are challenging. Our new technique can remove sub-ILM hemorrhage with the central fovea ILM intact, without peeling the ILM. The medical records of three eyes from three patients with SMH and sub-ILM hemorrhage secondary to RAM rupture were retrospectively reviewed. During the surgery, a small ILM fissure was made outside the central fovea with ILM forceps, and sub-ILM hemorrhage was washed out through it by manually spraying balanced salt solution. Sub-ILM hemorrhage removal was achieved successfully in all eyes, with no occurrences of FTMH or other complications. Best-corrected decimal visual acuity improved from 0.05 (Snellen equivalent (SE), 20/400), 0.05 (SE, 20/400), and 0.05 (SE, 20/400) preoperatively to 0.3 (SE, 20/63), 0.4 (SE, 20/50), and 0.15 (SE, 20/125) at 3 months postoperatively, respectively. This new technique may help keep the foveal ILM intact and prevent perioperative FTMH formation.
RESUMEN
Background and Objectives: Faricimab is a novel bispecific antibody with Fab regions inhibiting both vascular endothelial growth factor-A and angiopoietin-2. Therefore, this study aimed to obtain short-term outcomes of intravitreal injection of faricimab (IVF) for the treatment of diabetic macular edema (DME) in daily clinical practice. Materials and Methods: A retrospective review was carried out on consecutive patients with DME who had been treated with IVF and were followed up for at least 1 month. Outcome measures included changes in logMAR best-corrected visual acuity (logMAR BCVA), central retinal thickness (CRT), number of IVF administrations, and safety. Clinical outcomes were also compared between the treatment-naïve and switch groups. Results: A total of 21 consecutive DME eyes from 19 patients were identified. The mean number of IVFs was 1.6 ± 0.8 during the mean follow-up time of 5.5 months. The overall mean logMAR BCVA following IVF was 0.236, 0.204, 0.190, and 0.224 at baseline, 1, 3, and 6 months, respectively, without a significant change from baseline to 1 month (p = 0.176) or for 6 months (p = 0.923). The overall mean CRT (µm) following IVF was 400.6, 346.6, 342.1, and 327.5 at baseline, 1, 3, and 6 months, respectively. CRT significantly decreased from baseline to 1 month (p = 0.001) but did not reach a significant level over 6 months following IVF (p = 0.070). No significant difference in BCVA or CRT was observed between the treatment-naïve and switch groups. No serious safety concerns were noted. Conclusions: IVF for the treatment of DME may preserve visual acuity and improve macular thickness without serious safety concerns in the short term in a real-world clinical setting.

PURPOSE: The aim of this study is to explore the clinical features and associated factors of intraocular inflammation (IOI) following intravitreal brolucizumab (IVBr) administration for neovascular age-related macular degeneration (nAMD). METHODS: This retrospective study included 87 eyes from 87 Japanese patients with nAMD who were followed up for 5 months after the initial administration of IVBr as switching therapy. Clinical pictures of IOI post-IVBr and changes in best corrected visual acuity (BCVA) at 5 months were evaluated between eyes with and without IOI (non-IOI). The association between IOI and baseline factors (age, sex, BCVA, hypertension, and/or arteriosclerotic changes in the fundus, subretinal hyperreflective material [SHRM], and macular atrophy) was evaluated. RESULTS: Of the 87 eyes, 18 (20.6%) developed IOI and 2 (2.3%) developed retinal artery occlusion. There were 9 (50%) cases of posterior or pan-uveitis among eyes with IOI. The mean interval from initial IVBr administration to IOI was 2 months. The mean changes in logMAR BCVA at 5 months were significantly worse in IOI eyes than in non-IOI eyes (0.09 ± 0.22 vs. - 0.01 ± 0.15, P = 0.03). There were 8 (44.4%) and 7 (10.1%) cases of macular atrophy and 11 (61.1%) and 13 (18.8%) cases of SHRM in the IOI and non-IOI groups, respectively. SHRM and macular atrophy were significantly associated with IOI (P = 0.0008 and P = 0.002, respectively). CONCLUSION: In IVBr therapy for nAMD, eyes with SHRM and/or macular atrophy should be observed more meticulously, given the increased risk of developing IOI, which is associated with insufficient BCVA gain.

PURPOSE: We investigated potential risk factors for visual prognosis in Japanese patients with exogenous endophthalmitis. METHODS: In this retrospective observational multicenter cohort study, risk factors for legal blindness at 12 weeks after treatment initiation were evaluated based on patient characteristics, initial BCVA, causative events, pathogens, ocular symptoms, duration from symptom onset to initial treatment, and selected treatments. RESULTS: Overall, 23.1% of eyes developed legal blindness. The six risk factors for legal blindness were presence of eye pain, pathogen identification, poor BCVA at the initial visit, longer duration from symptom onset to initial treatment, type of causative event, and type of causative pathogen. Regarding the type of causative pathogen, coagulase-negative staphylococci was associated with a better visual impairment outcome. CONCLUSION: Exogenous endophthalmitis remains a severe ocular infection; however, it can be managed with rapid treatment, as well as other advances in medical knowledge and technology.
RESUMEN
PURPOSE: To investigate the genetic architecture of age-related macular degeneration (AMD) in a Japanese population. DESIGN: Genome-wide association study (GWAS). PARTICIPANTS: Three thousand seven hundred seventy-two patients with AMD and 16 770 control participants from the Japanese population were enrolled in the association analyses. METHODS: We conducted a meta-analysis of 2 independent GWASs that included a total of 2663 patients with AMD and 9471 control participants using the imputation reference panel for genotype imputation specified for the Japanese population (n = 3541). A replication study was performed using an independent set of 1109 patients with AMD and 7299 control participants. MAIN OUTCOME MEASURES: Associations of genetic variants with AMD. RESULTS: A meta-analysis of the 2 GWASs identified 6 loci significantly associated with AMD (P < 5.0 × 10-8). Of these loci, 4 were known to be associated with AMD (CFH, C2/FB, TNFRSF10A, and ARMS2), and 2 were novel (rs4147157 near WBP1L and rs76228488 near GATA5). The newly identified associations were confirmed in a replication study (P < 0.01). After the meta-analysis of all datasets, we observed strong associations in these loci (P = 1.88 × 10-12 and P = 1.35 × 10-9 for meta-analysis for rs4147157 and rs76228488, respectively). When we looked up the associations in the reported central serous chorioretinopathy (CSC) GWAS conducted in the Japanese population, both loci were associated significantly with CSC (P = 4.86 × 10-3 and P = 4.28 × 10-3 for rs4147157 and rs76228488, respectively). We performed a genetic colocalization analysis for these loci and estimated that the posterior probabilities of shared causal variants between AMD and CSC were 0.39 and 0.60 for WBP1L and GATA5, respectively. Genetic correlation analysis focusing on the epidemiologically suggested clinical risk factors implicated shared polygenic architecture between AMD and smoking cessation (rg [the measure of genetic correlation] = -0.33; P = 0.01; false discovery rate, 0.099). CONCLUSIONS: Our findings imply shared genetic components conferring the risk of both AMD and CSC. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

PURPOSE: We investigated potential predictive factors for visual prognosis in Japanese patients with endogenous endophthalmitis. DESIGN: Retrospective observational multicenter cohort study. METHODS: We examined the characteristics of 77 Japanese patients with endogenous endophthalmitis and performed statistical analyses of these real-world data. The primary endpoint was the identification of factors associated with visual prognosis. We examined differences between patients in the better vision and legal blindness groups at 12 weeks after treatment initiation. RESULTS: The five risk factors for visual impairment at 12 weeks after treatment initiation were presence of pressure injuries, severe clinical symptoms (presence of eye pain and ciliary injection), pathogen identification, and poor best-corrected visual acuity at baseline. Staphylococcus aureus and fungus were associated with a better visual impairment outcome. CONCLUSIONS: Endogenous endophthalmitis remains a severe ocular infection; however, it can be managed with rapid treatments, as well as other advances in medical knowledge and technology.

PURPOSE: To show the usefulness of the intraoperative three-dimensional fluorescein angiography (3D-FA)-guided pars plana vitrectomy. METHODS: The NGENUITY 3D visualization system was used for the digital assisted vitrectomy. Three-dimensional fluorescein angiography-guided pars plana vitrectomy was performed in three patients with vitreous hemorrhage secondary to proliferative diabetic retinopathy. We investigated both whether several angiographic findings can be successfully displayed on the screen during 3D-FA and whether pars plana vitrectomy can be performed simultaneously on the same screen while implementing 3D-FA. RESULTS: In all cases, the abnormal FA findings including hypofluorescence due to non-perfusion areas, and the hyperfluorescence due to macular edema and fibrovascular proliferative membrane were successfully displayed on the screen. The segmentation and delamination of fibrovascular proliferative membrane and panretinal photocoagulation for detected non-perfusion areas were able to be performed on the same screen while implementing 3D-FA. CONCLUSION: Three-dimensional fluorescein angiography-guided pars plana vitrectomy is a novel approach that fully utilizes the advantages of digital assisted vitrectomy and a promising option for the treatment of proliferative diabetic retinopathy.

PURPOSE: To report the case of a patient with cystoid macular edema secondary to idiopathic macular telangiectasia (MacTel) Type 1, which was successfully treated by cystotomy and en bloc removal of the fibrinogen-rich component of the cystoid lesion. METHODS: An 80-year-old man was referred to our department because of a visual defect in his right eye. His best-corrected decimal visual acuity was 0.7 (Snellen equivalent, 20/30). A fundus examination revealed clustered temporal juxafoveal microaneurysms and foveal cystoid macular edema. The patient refused to undergo conventional treatments, including direct retinal photocoagulation for microaneurysms, intravitreal anti-vascular endothelial growth factor injection, and intravitreal triamcinolone injection. However, he provided consent to undergo cystotomy and en bloc removal of the fibrinogen-rich component of the cystoid lesion. RESULTS: His best-corrected decimal visual acuity was 0.2 (Snellen equivalent, 20/100) just before the surgery. A 27-gauge vitrectomy with internal limiting membrane peeling was performed. Cystotomy was performed during the surgery, and the fibrinogen clot visible in the cystoid cavity was also removed. Cystoid macular edema rapidly disappeared after the surgery. Three years postoperatively, the patient had best-corrected decimal visual acuity of 0.5 (Snellen equivalent, 20/40) at the last medical examination, and the cystoid macular edema had not recurred. CONCLUSION: Cystotomy and en bloc removal of the fibrinogen-rich component of the cystoid lesion could be valid treatment options for cystoid macular edema secondary to MacTel Type 1.

PURPOSE: To report the usefulness of a new surgical method using intraoperative optical coherence tomography that can more accurately place the buckling material for scleral buckling using a noncontact wide-angle viewing system with a cannula-based chandelier endoilluminator for the treatment of rhegmatogenous retinal detachment. METHODS: The medical records of 12 eyes of 11 patients with rhegmatogenous retinal detachment treated with scleral buckling combined with real-time intraoperative optical coherence tomography observation were retrospectively reviewed. RESULTS: Real-time observations of the positional relationship between the protrusion of buckling material and retinal breaks with intraoperative optical coherence tomography revealed that retinal breaks were not properly placed on the protrusion of the buckling material in five eyes, requiring the intraoperative repositioning of the buckling material. Eventually, the scleral buckling combined with real-time intraoperative optical coherence tomography observation yielded the initial anatomical success rates of 100% without noteworthy intraoperative or postoperative complications. CONCLUSION: This procedure is a novel approach that enables safer and more accurate placement of the buckling material and may contribute to improving the outcomes of scleral buckling in the future.

PURPOSE: To evaluate the clinical characteristics, treatment trends, and visual prognosis of submacular hemorrhage (SMH) secondary to neovascular age-related macular degeneration (nAMD) and retinal arterial macroaneurysm (RAM). METHODS: This retrospective study enrolled 187 Japanese patients with SMH at 10 institutions from 2015 to 2018. Medical records including SMH etiology, best-corrected visual acuity (BCVA), fundus photographs, optical coherence tomography images, and selected treatments were analyzed. RESULTS: Major causes of SMH were typical nAMD (tnAMD) (18%), polypoidal choroidal vasculopathy (PCV) (50%) and RAM (29%). Age, male/female ratio, baseline BCVA, central retinal thickness, and involved retinal layers were significantly different between etiologies (all P<0.0001). Treatment with anti-vascular endothelial growth factor drugs with and without intravitreal gas injection was chosen for half of eyes in the tnAMD and PCV groups, whereas vitrectomy was performed in 83.7% of eyes with RAM. The final BCVA improved significantly from baseline in the PCV and RAM groups (P = 0.0009, P<0.0001) and final BCVA was significantly better in the PCV group at a level similar to the other groups (P = 0.0007, P = 0.0008). BCVA improvement from baseline was significantly greater in the RAM group compared with the tnAMD (P = 0.0152) and PCV (P = 0.017) groups. Multivariate analysis revealed better final BCVA was significantly associated with younger age (P = 0.0054), better baseline BCVA (P = 0.0021), RAM subtype (P = 0.0446), and no tnAMD (P = 0.001). CONCLUSIONS: The characteristics of, and treatment strategy for, SMH were different between the underlying diseases. Anti-vascular endothelial growth factor treatment with or without expansile gas was mainly chosen for SMH in tnAMD and PCV, whereas vitrectomy with gas was the most common treatment for RAM, and the higher rate for vitrectomy might result in the greater BCVA improvement in the RAM group than in the other groups. Final BCVA was better in PCV, RAM, and tnAMD, in that order, because patients with PCV were younger and had better baseline BCVA.
