RESUMO
Purpose: To elucidate the clinical characteristics and progression rates of pachychoroid and conventional geographic atrophy (GA). Design: Retrospective, multicenter, observational study. Participants: A total of 173 eyes from 173 patients (38 eyes with pachychoroid GA and 135 with conventional GA) from 6 university hospitals in Japan were included. All patients were Japanese, aged ≥50 years and with fundus autofluorescence images having analyzable image quality. A total of 101 eyes (22 with pachychoroid GA and 79 with conventional GA) were included in the follow-up group. Methods: The studied eyes were classified as having pachychoroid or conventional GA; the former was diagnosed if the eye had features of pachychoroid and no drusen. The GA area was semiautomatically measured on fundus autofluorescence images, and the GA progression rate was calculated for the follow-up group. Multivariable linear regression analysis was used to determine whether the rate of GA progression was associated with GA subtype. Main Outcome Measures: Clinical characteristics and progression rates of pachychoroid and conventional GA. Results: The pachychoroid GA group was significantly younger (70.3 vs. 78.7 years; P < 0.001), more male-dominant (89.5 vs. 55.6%; P < 0.001), and had better best-corrected visual acuity (0.15 vs. 0.40 in logarithm of the minimum angle of resolution; P = 0.002), thicker choroid (312.4 vs. 161.6 µm; P < 0.001), higher rate of unifocal GA type (94.7 vs. 49.6%; P < 0.001), and smaller GA area (0.59 vs. 3.76 mm2;P < 0.001) than the conventional GA group. In the follow-up group, the mean GA progression rate (square-root transformation) was significantly lower in the pachychoroid GA group than in the conventional GA group (0.11 vs. 0.27 mm/year; P < 0.001). Conclusions: Demographic and ocular characteristics differed between GA subtypes. The progression rate of pachychoroid GA, adjusted for age and baseline GA area, was significantly lower than that of conventional GA. Japanese patients with conventional GA showed characteristics and progression rates similar to those in White populations. Some characteristics of GA in Japanese population differ from those in Waucasian populations, which may be due to the inclusion of pachychoroid GA.

RESUMO
BACKGROUND: Recently, faricimab was approved as the new drug for neovascular age-related macular degeneration (nAMD). We lack the knowledge to choose between the existing drug and this new drug to use for treatment-naïve nAMD cases. In this study, we compared the functional and morphologic effects in loading dose between patients with treatment-naïve nAMD treated with either intravitreal aflibercept (IVA) or intravitreal faricimab (IVF) injection in a clinical setting. METHOD: This retrospective study included 30 eyes of 28 patients who started treatment with IVA between June and September 2022 and 30 eyes of 29 patients who were administered IVF between October 2022 and March 2023. All patients received three monthly IVA or IVF. The best corrected visual acuity (BCVA), central retinal thickness (CRT), and the proportion of eyes with residual exudative change at baseline and 1,2, and 3 months after initial treatment were compared between the groups. RESULTS: The mean BCVA significantly improved from pre-treatment after the loading dose in the IVA group (0.46 ± 0.46-0.36 ± 0.37, p = 0.0047) but not in the IVF group (0.46 ± 0.41-0.44 ± 0.45, p = 0.60). The mean CRT significantly improved in both groups. The proportion of eyes with residual exudative change was greater in the IVF group than in the IVA group 2 months after the first treatment (p = 0.026). The analysis of cases that achieved complete resolution of exudative changes after the loading dose showed that the IVA group had a significant improvement in the BCVA, whereas the IVF group did not (p = 0.0047 and 0.20, respectively). CONCLUSIONS: Although both IVA and IVF significantly improved CRT, the BCVA improved significantly in the IVA group but not in the IVF group.
RESUMO
Intravitreal injection of aflibercept (IVA) has successfully treated polypoidal choroidal vasculopathy (PCV), and polyp morphology is an important indicator of treatment efficacy. However, many studies have not reported the presence or absence of polyp regression and treatment outcomes, and few studies have reported polyp reduction and treatment outcomes in cases with residual polyps. We retrospectively measured the polyp area on indocyanine green angiography images before and after the IVA loading phase and investigated the regression and reduction of polyps and treatment outcomes of 81 eyes with PCV treated with IVA. We investigated the relationship between the presence or absence of complete regression of polyps and the percentage change in the polyp area and treatment outcomes. Eyes with complete polyp regression had significantly better visual acuity improvements compared with baseline at 12 months (P = 0.0108), fewer treatments (P = 0.0024), fewer recurrences during 12-months follow-up (P = 0.0010), and more "dry maculas" at 3 months (P = 0.0048) than eyes in which polyp regression did not occur. A significant correlation was seen only between the percentage of polyp regression and visual acuity at 3 months (P = 0.0395). Regarding IVA therapy for PCV, the presence or absence of complete polyp regression at the end of the loading phase affected the treatment outcome, whereas the degree of polyp reduction in cases of residual polyps had no effect.

Purpose: To utilize volumetric analysis to quantify volumetric changes in choroidal vessels and stroma after photodynamic therapy (PDT) and focal laser photocoagulation (PC) for central serous chorioretinopathy (CSCR). Methods: This retrospective, comparative study included 58 eyes (58 patients) with CSCR (PC, 33 eyes; PDT, 25 eyes) followed up with swept-source optical coherence tomography at 3 months after treatment. Three-dimensional (3D) choroidal vessel and stromal volumes in each area of the central 1.5-mm-diameter circle, the torus-shaped area with 6-mm-diameter circle excluding the area of the central 1.5-mm-diameter circle, and the treated area of the Early Treatment Diabetic Retinopathy Study (ETDRS) grid centered at the fovea were analyzed using a deep learning-based method. Changes in volume at baseline and 1 and 3 months after treatment were compared. Results: The mean patient age was 49.3 ± 10.5 years. In the central 1.5-mm-diameter circle, the mean vessel and stromal volume rates significantly decreased after the treatment in both the PDT and PC groups (P = 0.00029 and P = 0.0014, respectively), and significant differences between the PDT and PC groups of continuous variables within times were observed in both volumes (P = 0.024 and P = 0.037, respectively). In the torus-shaped area and treated area, the PDT and PC groups both showed similar decreases in vessel and stromal volume over time. Conclusions: In the 3D optical coherence tomography volumetric analysis, both PDT and focal PC reduced choroid vessel volume in eyes with CSCR. Translational Relevance: This new finding is useful in elucidating the pathogenesis and healing mechanisms of CSCR.

Purpose: Myopic choroidal neovascularization (CNV) and myopic traction maculopathy are major complications of pathologic myopia, and myopic foveoschisis (MF) is one of several symptoms that can be included under the general term "myopic traction maculopathy"; however, only a few cases will have MF around the myopic CNV. We report three cases with MF around myopic CNV that followed different clinical courses observed using swept-source optical coherence tomography. Observations: Case 1 was a 69-year-old woman with an axial length of 29.71 mm, myopic CNV, and MF in the left eye. One month after intravitreal injection of ranibizumab (IVR), a macular retinal detachment (RD) expanded. Vitrectomy and gas tamponade were performed during month 2; the macular RD and MF resolved gradually thereafter. Case 2 was a 54-year-old man with an axial length of 30.59 mm, myopic CNV, and MF in the right eye; after IVR, a macular RD developed and gradually expanded until month 4; the RD and MF resolved spontaneously and resolved during month 8. Case 3 was a 66-year-old woman with an axial length of 28.63 mm, myopic CNV, and MF in the left eye. A macular RD expanded 1 month after a previous vitrectomy for MF; after intravitreal injection of aflibercept, the macular RD and MF resolved gradually in month 12. In all cases, the CNV was accompanied by subretinal fluid, and two of the three cases had outer lamellar holes. Conclusion and Importance: The MF around the myopic CNV may lead to exacerbated MF and RD during follow-up, and the subretinal fluid caused by the CNV might facilitate MF progression. Since this condition is rare, further investigation of this entity is needed to determine appropriate management.
RESUMO
Purpose: To evaluate the relationship between full-thickness macular hole (FTMH) onset and perifoveal posterior vitreous detachment using OCT data. Design: Retrospective study. Participants: A total of 742 patients with FTMH or impending macular hole (MH) in ≥ 1 eye, as determined by ophthalmoscopy and OCT. Methods: Macular holes were staged using OCT results. Patients with the posterior vitreous membrane clearly detected in the OCT images and vitreoretinal adhesion size ≤ 1500 µm-eyes with MH stages 1-3-were included in the study. The contralateral eyes were also included in the analyses if they showed the focal type of vitreomacular adhesion (VMA) (i.e., vitreoretinal adhesion ≤ 1500 µm). The distance between the posterior vitreous membrane and the surface of the retina was defined as the posterior vitreous separation height (PVSH). Using the OCT images, PVSHs of each eye in 4 directions (nasal, temporal, superior, and inferior) at 1 mm from the center of the MH or fovea were calculated. Main Outcome Measures: The main outcome measures were PVSHs according to the MH stage and VMA, the relationship of the foveal inner tear with PVSH, and the likelihood of a foveal inner tear based on the direction. Results: The PVSH trends in each of the 4 directions were as follows: VMA < MH stage 1 = MH stage 2 < MH stage 3. Initial MH stage 2 (onset of FTMH) was defined as the presence of a gap in only 1 of the 4 directions from the center of the MH. With increased PVSH, the likelihood of a gap increased (P = 0.002), and a temporal gap was more likely to occur than a nasal gap (P = 0.002). Conclusions: At FTMH onset, a foveal inner tear likely appears on the temporal side or the side showing a high PVSH value.

RESUMO
PURPOSE: To evaluate the influence of tamponade on the visual and anatomic outcomes of pars plana vitrectomy for myopic traction maculopathy (MTM). DESIGN: Multicenter, retrospective clinical cohort study. METHODS: Consecutive eyes that underwent vitrectomy for advanced MTM with tamponade of air, sulfur hexafluoride (SF6), or perfluoropropane (C3F8) or without tamponade with a minimum follow-up of 12 months were included. Main outcome measures included postoperative visual acuity (VA) at 12 months in eyes with vs without tamponade. RESULTS: We included a total of 193 eyes (193 patients) in this study; 136 eyes (70%) treated with tamponade were compared with 57 eyes (30%) treated without tamponade. Baseline characteristics did not differ significantly between the groups. Both groups showed significant visual improvement at 12 months (both P < .001). However, postoperative visual acuity and visual improvement at 12 months were significantly better (P = .003 and P = .028, respectively) in eyes without tamponade, although the MTM in these eyes without tamponade took longer to resolve (P = .039). Retinal thickness and the ellipsoid zone were more preserved in eyes without tamponade (P < .001 and P = .001, respectively). Complications such as macular holes did not differ between the groups. A novel imaging finding of "schisis bending (accordioning)" was identified during MTM resolution. CONCLUSIONS: Vitrectomy either with or without tamponade for MTM was effective in improving vision in this study. However, eyes without tamponade experienced even better visual improvement and preserved retinal anatomy, despite a longer schisis resolution time. Surgery without tamponade may achieve better visual outcomes.

PURPOSE: To elucidate the clinical characteristics and progression rate of geographic atrophy (GA) associated with age-related macular degeneration (AMD) in a Japanese population. DESIGN: Retrospective, multicenter, observational study. PARTICIPANTS: A total of 173 eyes from 173 patients from 6 university hospitals in Japan were included. Of 173 study eyes, 101 eyes from 101 patients were included in the follow-up group. All patients were Japanese, aged ≥ 50 years and had definite GA associated with AMD in at least 1 eye. METHODS: The GA area was measured semiautomatically using fundus autofluorescence (FAF) images. In the follow-up group followed for > 6 months with FAF images, the GA progression rate was calculated by 2 methods: mm2 per year and mm per year using the square-root transformation (SQRT) strategy. Simple and multiple linear regression analyses were used to identify the baseline factors associated with the GA progression rate. MAIN OUTCOME MEASURES: Clinical characteristics of GA and the GA progression rate. RESULTS: The mean age was 76.8 ± 8.8 years, and 109 (63.0%) were males. Sixty-two (35.8%) patients had bilateral GA. The mean GA area was 3.06 ± 4.00 mm2 (1.44 ± 1.00 mm [SQRT]). Thirty-eight eyes (22.0%) were classified as having pachychoroid GA. Drusen and reticular pseudodrusen were detected in 115 (66.5%) and 73 (42.2%) eyes, respectively. The mean subfoveal choroidal thickness was 194.7 ± 105.5 µm. In the follow-up group (follow-up period: 46.2 ± 28.9 months), the mean GA progression rate was 1.01 ± 1.09 mm2 per year (0.23 ± 0.18 mm/year [SQRT]). In the multivariable analysis, the baseline GA area (SQRT; P = 0.002) and the presence of reticular pseudodrusen (P < 0.001) were significantly associated with a greater GA progression rate (SQRT). CONCLUSIONS: Certain clinical characteristics of GA in Asian populations may differ from those in White populations. Asian patients with GA showed male dominance and relatively thicker choroid than White patients. There was a group with GA without drusen but with features of pachychoroid. The GA progression rate in this Asian population was relatively lower than that in White populations. Large GA and reticular pseudodrusen were associated with a greater GA progression rate.

Background: During the treatment of age-related macular degeneration with anti-vascular endothelial growth factor (VEGF) drugs, we often see cases with anti-VEGF-resistant refractory subretinal fluid. In this report, we present two cases of anti-VEGF-resistant refractory age-related macular degeneration (AMD) due to the concurrent development of central serous chorioretinopathy (CSCR) in eyes previously well controlled with intravitreal anti-VEGF injections. Case presentation: Two patients underwent intravitreal aflibercept for the treatment of neovascular AMD. Initially, both patients responded well to intravitreal aflibercept, resulting in the complete resolution of the subretinal fluid. However, both patients subsequently developed sudden-onset refractory subretinal fluid that did not respond to repeated intravitreal aflibercept. Fluorescein angiography, indocyanine green angiography, and swept-source optical coherence tomography revealed focal leakage spots, choroidal hyperpermeability, and dilated choroidal vessels, respectively, which were distinct from the pre-existing choroidal neovascularization and suggestive of newly developed CSCR. Laser photocoagulation of the leak spots resulted in the complete resolution of the once-refractory subretinal fluid and the maintenance of vision. Conclusions: Our cases highlight that anti-VEGF-refractory subretinal fluid may occur secondary to concurrent CSCR in patients receiving regular anti-VEGF treatments for AMD. In those patients, treatment for CSCR is effective for controlling subretinal fluid that is unresolved by anti-VEGF treatment.
RESUMO
OBJECTIVE: Nicotinamide adenine dinucleotide regulates various biological processes. Nicotinamide mononucleotide (NMN) increases its intracellular levels and counteracts age-associated changes in animal models. We investigated the safety and efficacy of oral nicotinamide mononucleotide supplementation in older patients with diabetes and impaired physical performance. METHOD: We carried out a 24-week placebo-controlled, double-blinded study of male patients with diabetes aged ≥65 years with reduced grip strength (<26 kg) or walking speed (<1.0 m/s). The primary end-points were to determine the safety of NMN oral administration (250 mg/day), and changes in grip strength and walking speed. The secondary end-points were to determine the changes in various exploratory indicators. RESULTS: We studied 14 participants aged 81.1 ± 6.4 years. NMN was tolerable without any severe adverse events. The changes in grip strength and walking speed showed no difference between the two groups: 1.25 kg (95% confidence interval -2.31 to 4.81) and 0.033 m/s (-0.021 to 0.087) in the NMN group, and -0.44 kg (-4.15 to 3.26) and 0.014 m/s (-0.16 to -0.13) in the placebo group, respectively. There were no significant differences in any exploratory indicators between the two groups. However, improved prevalence of frailty in the NMN group (P = 0.066) and different changes in central retinal thickness between the two groups (P = 0.051) was observed. CONCLUSION: In older male patients with diabetes and impaired physical performance, NMN supplementation for 24 weeks was safe, but did not improve grip strength and walking speed.

PURPOSE: To investigate the outcomes of intravitreal aflibercept and gas injections for submacular hemorrhage (SMH) associated with polypoidal choroidal vasculopathy (PCV). METHODS: We retrospectively reviewed the medical records of 22 eyes with SMH secondary to PCV that underwent intravitreal aflibercept and 100% perfluoropropane (0.3-0.5 mL) followed by 3-day prone positioning from August 2013 through November 2020. The primary outcome measure was best-corrected visual acuity (BCVA) at 12 months. RESULTS: The average SMH size was 13.0 ± 9.7 (range, 2.0-37.8) disc diameter. The complete, partial, and no displacement of the SMH was observed in 8 (36%) eyes, 9 (41%) eyes, and 5 (23%) eyes, respectively. The BCVA (logarithm of the minimum angle of resolution) continuously improved significantly from 0.81 ± 0.41 (Snellen equivalent, 20/125) at baseline to 0.48 ± 0.44 (20/60), 0.33 ± 0.39 (20/43), and 0.28 ± 0.45 (20/38), at 3, 6, and 12 months, respectively (P = 0.01 for 3 months; P < 0.001 for 6 and 12 months). The BCVA improved by 3 or more lines in 14 eyes (64%). Two eyes (9%) developed visually significant vitreous hemorrhage, and 1 (5%) eye developed rhegmatogenous retinal detachment; all were successfully treated with vitrectomy. The better BCVA at 12 months tended to be associated with lower height of the SMH at baseline (R2 = 0.171, P = 0.056) and a greater displacement of SMH (R2 = 0.244, P = 0.069). Worse BCVA at 12 months was associated with anticoagulant medication (P < 0.001). CONCLUSIONS: Intravitreal aflibercept and gas injections are effective and relatively safe for SMH associated with PCV, resulting in significant visual improvement.

Purpose: To define the role of optociliary shunt vessels (OSVs) in eyes with central retinal vein occlusion (CRVO) using OCT angiography (OCTA) with macular parameters. Design: Retrospective, observational, consecutive case series. Participants: Forty-one eyes in 38 consecutive patients with CRVO were analyzed in this study. Methods: Optic disc and macula were imaged by swept-source OCTA (3 × 3 mm) as well as by high-quality fundus photography. Main Outcome Measures: We compared macular vessel density (VD) and visual acuity between eyes in which OSVs developed and those in which they did not. Furthermore, we measured the diameter of the OSVs and analyzed the correlation with macular VD and visual acuity. Results: Optociliary shunt vessels were found in 25 eyes (61%). Central retinal vein occlusion with OSVs did not show any statistical difference compared with CRVO without OSVs in either macular VD of the total retina (0.31 ± 0.07 and 0.26 ± 0.09, respectively; P = 0.0937) or final best-corrected visual acuity (BCVA) (0.30 ± 0.43 logarithm of the minimum angle of resolution [logMAR] and 0.59 ± 0.54 logMAR, respectively; P = 0.0705). The mean OSV diameter was 71 ± 30 µm in CRVO with OSV. The diameter of the OSVs was correlated positively with superficial VD (r = 0.443; P = 0.027), deep VD (r = 0.494; P = 0.012), and total VD (r = 0.491; P = 0.013). Furthermore, the OSV diameter was also negatively correlated with BCVA (logMAR) at the final visit (r = -0.531; P = 0.006). Conclusions: The results demonstrated that the diameter of the OSVs was associated with macular VD and visual acuity in patients with CRVO. The development of large OSVs on the optic disc may be a good indicator of the maintenance of blood flow in the macula.
RESUMO
Introduction: This study aimed to describe the quantitative features of the microvasculature in the cystic lesions of branch retinal vein occlusion (BRVO). Methods: A total of 43 eyes with BRVO, treated with anti-vascular endothelial growth factor therapy, were analyzed. Using wide-field swept-source optical coherence tomography angiography (OCTA), en face OCT images were obtained by depth-integrated reflectivity of the retina, and vascular density (VD), vascular length (VL), vascular lacunarity, and fractal dimension (FD) were evaluated in a 12 × 12-mm area of retinal nonperfusion. Results: The mean area of affected lesions was 38.7 ± 19.8 mm2, and cystic lesions were 8.5 ± 10.1 mm2. VD, VL, and FD were significantly decreased in the cystic lesions compared to other affected lesions in the same eyes (p = 0.0010, p = 0.0001, and p = 0.0003, respectively) and in all eyes (p = 0.0281, p = 0.0050, and p < 0.0001, respectively). VD in cystic lesions within the vascular arcade (25 eyes) correlated with best-corrected visual acuity on OCTA (r = -0.433, and p = 0.0492). Conclusions: Vascular structure in the cystic lesions was unpreserved compared to the other lesions in BRVO. These findings may help in understanding the pathophysiology of retinal edema in BRVO.
RESUMO
We present a case of a congenital retinal macrovessel (CRM) with spontaneous resolution of cystoid macular edema. A 39-year-old woman with sudden decreased vision in her right eye was referred to our clinic and found to have a CRM with macular edema. Her visual acuity was 20/25. A week later, the macular edema disappeared without any treatment, and her visual acuity was 20/15. We performed optical coherence tomography angiography and fluorescein angiography (FA), which revealed no obstruction of retinal flow but a slight disturbance of retinal flow near the central fovea on FA. We encountered a case of spontaneous resolution of macular edema with abnormal vessel crossing near the central macula by a CRM, and multimodal imaging was useful for investigating the pathology of the disease.
RESUMO
The META-Analysis of Pathologic Myopia Study group proposed a new classification system for myopic maculopathy (MM) with pathologic myopia (PM) defined as MM equal to/more serious than diffuse atrophy or the presence of plus lesions and myopic choroidal neovascularization (mCNV) defined as CNV in the eye with PM. However, CNV in elderly eyes with high myopia (HM) not meeting the PM definition (high-myopia CNV) are not classified as age-related macular degeneration (nAMD) or mCNV. This retrospective study included 39 eyes with high-myopia CNV, 20 eyes with mCNV, and 20 eyes with AMD. All patients were at least 40 years old. We compared the clinical characteristics and treatment outcomes among three groups. The high-myopia CNV group had significantly more CNV types, shorter axial length and fewer lacquer cracks (P < 0.0001, respectively); larger baseline greatest linear dimension (P = 0.0002), more fellow-eye drusen (P = 0.0106), more men (P = 0.0029), and more treatments (24 months, P = 0.0098) compared to the mCNV group. Compared with the nAMD group, the high-myopia CNV group was significantly younger (P = 0.0041), and had fewer CNV types (P = 0.0316), more lacquer cracks (P = 0.0079) and fewer drusen (affected-eye, P = 0.0006 and fellow-eye, P = 0.0222), and fewer treatments (24 months, P = 0.0030). Because the CNV in elderly eyes with HM not meeting the PM definition is classified as combined mCNV and nAMD, the clinical and angiographic findings are critical to determine the treatment strategy.

Background: The literature suggests that stress may play a pivotal role in the precipitation of acute central serous chorioretinopathy (CSC) because chorioretinal integrity can be affected by the psychosocial state of the patient, indicating the need for a biomarker. Not only physical stress but also psychological stress causes many types of physical disorders. However, little is known about the pathophysiology of stress-induced disease. The objective of this study was to investigate whether serum factors might be involved in the development of stress-induced ocular diseases. Methods: This observational case series included 33 eyes of 33 consecutive patients with treatment-naïve acute CSC. Fifty eyes of 50 age-matched healthy volunteers were included in this study as non-CSC controls. Serum samples were collected from all participants, and the levels of mitochondrial DNA (mtDNA) were measured by quantitative real-time (RT)-PCR. Serum levels of high-mobility group box (HMGB) 1 and 8-hydroxy-2'-deoxyguanosine (8-OHdG), biological markers of acute/chronic inflammation and oxidative stress, were also measured. The relationships between serum mtDNA, 8-OHdG, and HMGB1 concentrations were investigated by multivariate regression analysis, alongside an assessment of clinical data. Results: In the treatment-naïve acute CSC group, the serum mtDNA levels (36.5 ± 32.4 ng/mL) were significantly higher than the levels in the control group (7.4 ± 5.9 ng/mL; p < 0.001). Serum levels of 8-OHdG and HMGB1 in treatment-naïve acute CSC patients measured 0.12 ± 0.08 ng/mL and 18.1 ± 35.0 ng/mL, respectively, indicating that HMGB1 levels were elevated in CSC compared with the control group. Multivariable regression analysis demonstrated that increased serum mtDNA levels were significantly associated with the height of serous retinal detachment. Conclusion: We showed serum mtDNA and HMGB1 level elevation and its relation to the clinical activities of CSC, indicating that serum mtDNA and HMGB1 could serve as biomarkers for the acute phase of the disease. The use of these biomarkers makes it possible to predict disease onset and determine disease severity.
RESUMO
PURPOSE: To evaluate the progression of early age-related macular degeneration to neovascular age-related macular degeneration (nAMD), and identify the abnormal fundus autofluorescence (FAF) patterns and markers of choroidal neovascularization (CNV) in fellow eyes of patients with unilateral nAMD. METHODS: Sixty-six patients with unilateral nAMD who developed abnormal FAF in the fellow eyes were enrolled in this multicenter, prospective, observational study, and followed-up for 5 years. FAF images on Heidelberg Retina Angiogram Digital Angiography System (HRA) or HRA2 were classified into eight patterns based on the International Fundus Autofluorescence Classification Group system. The patients in which the fellow eyes progressed to advanced nAMD, including those who did not develop nAMD, were assessed based on the following factors: baseline FAF patterns, age, sex, visual acuity, drusen, retinal pigmentation, baseline retinal sensitivity, family history, smoking, supplement intake, hypertension, body mass index, and hematological parameters. RESULTS: Of the 66 patients, 20 dropped out of the study. Of the remaining 46 patients, 14 (30.42%, male: 9, female: 5) progressed to nAMD during the 5-year follow-up. The most common (50% eyes) FAF pattern in the fellow eyes was the patchy pattern. According to the univariate analysis, CNV development was significantly associated with age, supplement intake, and low-density lipoprotein levels (p<0.05). Multivariable analysis revealed that patients who showed non-compliance with the supplement intake were more likely to develop nAMD (p<0.05). No significant association was found between the patchy pattern and CNV development (p = 0.86). CONCLUSION: The fellow eyes (with abnormal FAF) of patients with unilateral nAMD may progress from early to advanced nAMD. However, no FAF pattern was found that predicted progression in nAMD.

PURPOSE: To report anterior chamber flare using laser flare photometry and ciliochoroidal detachment using anterior segment optical coherence tomography (AS-OCT) in a new onset acute lupus choroidopathy case. OBSERVATIONS: A 57-year-old woman with severe nephritis, pleural effusion, and ascites was referred to our ophthalmology clinic for rapid onset of bilateral blurred vision and eyelid swelling. She had a bilateral high-flared, shallow anterior chamber, and bilateral ciliochoroidal detachment, which was revealed using laser flare photometry and AS-OCT. She also had a serous retinal detachment and disc-macular retinoschisis with a thicker choroid and waved Bruch's membrane. Indocyanine green angiography (ICGA) demonstrated partial hypocyanescence in the early phase and multiple hypercyanescent spots at the intermediate to late phase, which are typical of lupus choroidopathy. Systemic lupus erythematosus was diagnosed, and after the administration of pulse methylprednisolone and pulse cyclophosphamide therapies, all eye findings completely resolved in a month, and all other signs and symptoms improved. CONCLUSIONS AND IMPORTANCE: Lupus choroidopathy, which is less common than retinopathy, might be under-diagnosed because of its difficult evaluation. Although ICGA is the gold standard for diagnosing lupus choroidopathy, a high flare of the anterior chamber and ciliochoroidal detachment might be different from lupus retinopathy. Laser flare photometry and AS-OCT can be non-invasive, helpful tools for the longitudinal evaluation of the patient's response to therapy.
