INCIDENCE AND RISK FACTORS OF INTRAOCULAR INFLAMMATION AFTER BROLUCIZUMAB TREATMENT IN JAPAN: A Multicenter Age-Related Macular Degeneration Study.

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.

Safety and efficacy of 27-gauge transconjunctival vitrectomy for the diagnosis of posterior uveitis or pan uveitis of unknown origin.

BACKGROUND: Diagnostic vitrectomy is an important method for evaluating uveitis, and its diagnostic utility is high regardless of whether the uveitis is infectious or non-infectious. The course of diagnostic vitreous surgery with 27-gauge pars plana vitrectomy and perioperative complications is reported. METHODS: An observational retrospective study of patients who underwent 27-gauge diagnostic vitrectomy due to atypical intraocular inflammation was conducted. The final diagnosis rate, complications due to surgery, preoperative visual acuity, and postoperative visual acuity (1 month and 6 months after surgery) were examined retrospectively. RESULTS: Diagnostic vitreous surgery was performed in 32 patients and 35 eyes (14 males and 18 females, age 14-85 years, median 67 years) during the study period. The average operation time was 52 min for 19 eyes with cataract surgery and 35 min for 16 eyes without cataract surgery. Preoperative log(minimum angle of resolution [MAR]) visual acuity was 0.84 ± 0.87, 1-month postoperative logMAR visual acuity was 0.41 ± 0.55 (p = 0.004, n = 28), and 6-month postoperative average logMAR visual acuity was 0.45 ± 0.73 (p = 0.012, n = 15). The diagnosis was made by diagnostic vitrectomy in 19 cases (54%). Postoperative complications were observed in 2 of 35 postoperative patients (5%); one involved increased intraocular pressure, and the other case involved vitreous hemorrhage of the eye, necessitating reoperation. CONCLUSION: Diagnostic 27-gauge vitrectomy could be effective for evaluating intraocular inflammation.

Selective retina therapy (SRT) for macular serous retinal detachment associated with tilted disc syndrome.

PURPOSE: Tilted disc syndrome (TDS) may be associated with a macular serous retinal detachment (MSRD). However, ideal therapy for this complication is still unestablished yet to date. The purpose of this study is to investigate the effect of selective retina therapy (SRT) for MSRD associated with TDS. METHODS: This retrospective study included 11 eyes of 10 patients (1 male and 9 females), who were treated with SRT for MSRD associated with TDS, and observed at least 12 months after treatment. The mean age was 56 years old (range 44-66). An SRT laser (527 nm, 1.7 µs, 100 Hz; Medical Laser Center Lübeck, Germany) was used for treatment. The changes of best-corrected visual acuity (BCVA), central macular thickness (CMT), and central choroidal thickness (CCT) were examined. Subfoveal curve height (SFCH) was calculated at baseline. RESULTS: The mean follow-up period was 24.4 months (range 12-48 months). The mean BCVA (logMAR), CMT, and CCT changed from 0.03 ± 0.10, 324 ± 82 µm, and 194 ± 68 µm preoperatively to 0.07 ± 0.17, 274 ± 94 µm, and 188 ± 65 µm at final follow-up, respectively, with significant difference on CMT (BCVA: p = 0.44, CMT: p < 0.05, CCT: p = 0.21). The MSRD disappeared in 6 eyes (55%) and the average number of SRT irradiations until resolution of MSRD was 2.6 times (range 1-5 times). There was no significant association between SFCH and resolution of MSRD (p = 0.19). CONCLUSIONS: SRT may promote absorption of MSRD and maintenance of BCVA for TDS. Randomized and prospective clinical studies are needed to evaluate the effectiveness of SRT for MSRD associated with TDS.

Visual outcomes and choroidal thickness associated with human leukocyte antigen DRB1*04 in unclassifiable uveitis in Japanese patients.

PURPOSE: Human leukocyte antigen (HLA) and immunity are related. Uveitis is also closely related to immunity. For example, the common presence of human leukocyte antigen (HLA)-DRB1*04 in the immune response is well known. The aim of this study was to investigate the relationship between visual prognosis and various HLA alleles before and after therapy in patients with unclassifiable uveitis, excluding those with Vogt-Koyanagi-Harada (VKH) disease. METHODS: This retrospective case series included 42 eyes from 22 consecutive patients with unclassifiable uveitis, excluding those with VKH disease. Visual acuity (VA), sex, refractive error, central retinal thickness (CRT), central choroidal thickness (CCT), and duration from onset to treatment were measured at initial and 6-month visits. Mean values of parameters were compared at each visit. Genotyping was performed by polymerase chain reaction amplification with sequence-specific primers. RESULTS: DRB1*04 showed a dominant change. No significant difference was observed in the other alleles. In DRB1*04, The mean differences in initial CCT, 6-month CCT, and 6-month VA showed statistically significant difference was found in best-corrected visual acuity (BCVA) between DRB1*04+ and DRB1*04- at the first visit. BCVA values at baseline and at the final visit were 0.13 ± 0.29 and 0.20 ± 0.36 in the DRB1*04+ and 0.00045 ± 0.20 and - 0.058 ± 0.11 in the DRB1*04- groups(p = 0.00465). Central Choroidal Thickness (CCT) values pretreatment and at the final visit after treatment were (pretreatment:361.00 ± 361.0 µm,after treatment: 286.00 ± 106.53 µm, p = 0.0174) in the DRB1*04+ group, and (pretreatment:281.3 ± 139.68 µm,after treatment:223.85 ± 99.034 µm, p = 0.0426) in the DRB1*04- group, respectively, indicating changes between baseline and the final visit. CCT was significantly greater in the DRB1*04+ group at both the initial visit and at 6 months. Multivariate analysis showed a significant difference between the presence or absence of DRB1*04 and sex. CONCLUSION: HLA-DRB1*04 allele may affect visual prognosis and CCT in unclassifiable uveitis.

Predictive factors of outcome of selective retina therapy for diabetic macular edema.

PURPOSE: To investigate the predictive factors of clinical outcome of selective retina therapy (SRT) for diabetic macular edema (DME). METHODS: This retrospective study included 22 eyes of 22 patients (15 males and 7 females), who were treated with SRT for DME at the Department of Ophthalmology of Osaka City University Hospital and observed at least 6 months after the treatment. The mean age was 64 years (range 40-81). Thirteen of the 22 eyes (59%) had a treatment history other than SRT before. SRT laser (527 nm, 1.7 µs, 100 Hz) was used for treatment. Changes in the best-corrected visual acuity (BCVA) (logMAR) and central macular thickness (CMT) in optical coherence tomography were examined at baseline, 3-month follow-up, and 6-month follow-up. Factors associated with the rate of change in CMT at 3 and 6 months after SRT were examined. RESULTS: The mean BCVA (logMAR) was 0.26 ± 0.31, 0.22 ± 0.27 and 0.23 ± 0.29 at baseline, 3 months and 6 months, respectively (p = 0.15 at 3 months, 0.40 at 6 months; compared to baseline). The mean CMT was 502 ± 163, 493 ± 204, and 416 ± 185 µm at baseline, 3 months, and 6 months, respectively (p = 0.69 at 3 months, 0.01 at 6 months; compared to baseline). The multivariate analysis found a significant negative association with previous macular photocoagulation (p = 0.03) at 3 months and a positive association with a history of insulin use (p = 0.02) and previous panretinal photocoagulation (p = 0.03) at 6 months after SRT. CONCLUSION: The CMT was significantly decreased at 6 months after SRT in DME. The history of insulin use and panretinal photocoagulation may positively and the history of macular photocoagulation may negatively affect the outcome of SRT, which must be considered when determining the therapeutic indications for SRT.

Correlation between visual acuity and human leukocyte antigen DRB1*04 in patients with Vogt-Koyanagi-Harada disease.

BACKGROUND: The common presence of human leukocyte antigen (HLA)-DRB1*04 in Vogt-Koyanagi-Harada (VKH) disease is well known. The aim of this study was to investigate the relationship between visual prognosis and HLA-DRB1*04 alleles during systemic corticosteroid therapy in patients with VKH disease. METHODS: This retrospective case series included 57 eyes from 29 consecutive patients with treatment-naïve VKH disease who received systemic corticosteroid therapy. Visual acuity, sex, refractive error, central retinal thickness (CRT), central choroidal thickness (CCT), and duration from onset to treatment were measured at initial and final visits. Mean values of parameters were compared with each visit. Genotyping was performed by polymerase chain reaction amplification with sequence-specific primer. RESULTS: Linear regression showed significant differences in logMAR best-corrected visual acuity between the three groups of homozygotes, heterozygotes, and normal subjects at baseline (p < 0.01), at 3 months after treatment (p < 0.01). There was no significant differences at 6 months after treatment (p = 0.257). No significant differences were detected between the three groups in age, sex, refractive error, CRT, CCT, or duration from onset to treatment. CONCLUSION: Alleles of HLA-DRB1*04 might affect visual prognosis and be related to early response after initiation of treatment in VKH disease.

Retinal sensitivity after selective retina therapy (SRT) on patients with central serous chorioretinopathy.

PURPOSE: To assess retinal sensitivity after selective retina therapy (SRT) in patients with central serous chorioretinopathy (CSCR). METHODS: Seventeen eyes of 17 patients with CSCR lasting longer than 3 months were treated with SRT (wavelength 527 nm Nd: YLF laser, 50-150 µJ/pulse, spot diameter 200 µm). Measurement of best-corrected visual acuity (BCVA), optical coherence tomography, fluorescence angiography, and microperimetry (MAIA™) were conducted before, and 1 and 3 months after treatment. Microperimetry was performed in the central 10° of the macula, and at the test spots applied near the vascular arcade for energy titration. In addition to the treatment effect, all test irradiation spots were thoroughly analyzed with regard to their sensitivity changes. RESULTS: The mean logMAR BCVA had improved from 0.06 to 0.02 after 1 month (p = 0.11) and to 0.03 after 3 months (p = 0.003). Eleven out of 17 eyes (64.7%) showed complete resolution of subretinal fluid after 3 months. Retinal sensitivity in the central 10° increased after 1 month (median: 25.9 dB) and 3 months (26.6 dB) as compared with that before treatment (23.0 dB) (p < 0.001). Analysis of the test spots revealed a slight decrease in retinal sensitivity after 1 month (ΔdB = -0.5 ± 2.1, p = 0.006), while there was no significant difference from baseline after 3 months (ΔdB = -0.3 ± 2.2, p = 0.09). No correlation was found between laser energy and the change in focal retinal sensitivity. CONCLUSIONS: Results suggest that SRT is a safe and effective treatment for persistent CSCR and does not leave permanent scotoma regardless of irradiation energy in the therapeutic range.

Traumatic myopia secondary to ciliary spasm after blunt eye trauma and reconsideration of its pathogenesis.

PURPOSE: To reconsider the pathogenesis of traumatic myopia by describing two cases and literature review. METHODS: Refraction was measured, A-scan ultrasonography was performed, and ultrasound biomicroscopy (UBM) was used to observe the ciliary body in the acute and recovery stages. RESULTS: The first patient had a myopic shift of -6.12 diopters (D) on the initial examination (day 2) compared with the recovered stage. UBM showed ciliochoroidal effusion in one half of the circumference and severe edema in three eighths of the ciliary body, which led to an anterior rotation of the ciliary body. Immediately after the cycloplegia, the myopic shift decreased by -3.9 D. On day 11, the refraction was -0.63 D, and the UBM findings were normalized. The second patient had a myopic shift of -4.38 D on the first examination compared with the recovered stage. UBM showed an annular ciliochoroidal effusion leading to anterior rotation of the ciliary body. Immediately after the cycloplegia, there was a decrease of -2.75 D. Biometric measurements showed an increased anterior chamber depth and a decreased thickness of the lens. On day 16, the refraction was -1.0 D, and the UBM findings were normalized. In both cases, biometric measurements in the acute phase suggested a anterior chamber shallowing, a thickening of the lens, and an anterior shift of the lens-iris diaphragm CONCLUSIONS: Cycloplegia decreased the myopic shift by more than 60 %. These findings indicate a significant contribution of ciliary spasm combined with ciliochoroidal effusion, anterior shift of the lens-iris diaphragm, and thickening of the lens.

Switching to Intravitreal Brolucizumab after Ranibizumab or Aflibercept Using Treat and Extend Regimen for Neovascular Age-Related Macular Degeneration in Japanese Patients: 1-Year Results and Factors Associated with Treatment Responsiveness.

Objective: To purpose of this study was to retrospectively evaluate the 1-year outcomes and factors associated with the treatment responsiveness of switching to intravitreal brolucizumab (IVBR) for neovascular age-related macular degeneration (nAMD) in Japanese patients refractory to ranibizumab or aflibercept using a treat and extend (TAE) regimen. Methods: A total of 48 eyes of 47 nAMD patients were switched to IVBR, and 36 eyes of 35 patients (27 males and 8 females) underwent 1-year treatment after the switch. Results: The rate of dry macula was significantly higher 12 months after the switch to IVBR (p < 0.001), with a significant decrease in the mean central macular thickness (CMT) and the mean central choroidal thickness (CCT) (p < 0.01 and p < 0.01, respectively). The injection interval was significantly extended from 7.0 ± 1.7 weeks to 10.3 ± 2.5 weeks 12 months after the switch (p < 0.001). In the multivariate analysis, a smaller number of prior anti-VEGF injections (p = 0.025; odds ratio: 0.947; 95% confidence interval: 0.903-0.994) and a pre-switching CCT of less than 250 µm (p = 0.023; odds ratio: 0.099; 95% confidence interval: 0.013-0.731) were associated with the good response group. Conclusions: These results suggest that IVBR may suppress disease activity and prolong the injection interval by switching for AMD patients with an insufficient response to treatment with ranibizumab and aflibercept.

Symptoms of Isolated Optic Neuropathy in a Patient with Systemic, Brain, and Meningeal Metastases from Breast Cancer: A Case Report.

Introduction: Ocular metastases from breast cancer, particularly involving the optic nerve, are rare and pose a diagnostic challenge. Typically, optic nerve metastases are believed to originate from nearby choroidal metastases or hematogenous spread through the posterior ciliary arteries. However, there have been some reports of metastases through leptomeningeal dissemination. The aim of this report was to describe a case of multiple brain metastases from breast cancer without subjective symptoms other than central scotoma, which was diagnosed with repeated magnetic resonance imaging (MRI). Case Presentation: A 62-year-old woman who had previously undergone a mastectomy for left breast cancer complained of left ocular pain during eye movement and left visual loss. Initial contrast-enhanced MRI showed no significant abnormalities, and idiopathic optic neuritis was suspected. Despite steroid pulse therapy, her visual function did not improve. After four and a half months, her visual acuity worsened, and repeat contrast-enhanced MRI showed brain metastases involving the optic nerve sheath. Conclusion: Despite the multiple brain metastases, ultimately the patient's only symptom was unilateral visual loss. These findings highlight the usefulness of repeated contrast-enhanced MRI for detecting brain metastases, especially in cases without other apparent neurological symptoms or initial imaging abnormalities.

The impact of removing the epiretinal membrane and inner limiting membrane for sustained subretinal fluid by macular neovascularization refractory to anti-VEGF therapy.

Purpose: Anti-vascular endothelial growth factor (VEGF) therapy is the most prevalent intervention for exudative lesions secondary to neovascular age-related macular degeneration (nAMD) and other macular neovascularization (MNV). However, in some cases refractory to the latest anti-VEGF agents is associated with epiretinal membrane (ERM) or vitreomacular traction. We applied a vitrectomy to remove those pathologies which may be effective for reducing the exudation. Observations: In this case report, we present 2 cases with sustained subretinal fluid and macular neovascularization secondary to nAMD or dome-shaped macula that poorly responded to anti-VEGF therapy. In both cases, removing thin ERM or vitreomacular traction with an inner limiting membrane peeling promptly resolved the subretinal fluid and no recurrence was observed thereafter. Conclusions and importance: Vitrectomy could be an effective modality for anti-VEGF drug-resistant MNV cases with vitreomacular traction or ERM even in the anti-VEGF era.

One-Year Outcome of Intravitreal Injection of Ranibizumab Biosimilar for Myopic Choroidal Neovascularization in Japanese Patients.

Objectives: To evaluate the one-year outcomes of intravitreal ranibizumab biosimilar (RBZ-BS) injections for myopic choroidal neovascularization (mCNV) in Japanese patients. Methods: Twenty-one patients (mean age 69.0 years; 4 males, 17 females) with high myopia and mCNV were retrospectively reviewed. Twelve were treatment-naïve, and nine had previous anti-VEGF treatments. Efficacy measures included best-corrected visual acuity (BCVA) and central macular thickness (CMT). Results: The treatment-naïve group showed significant BCVA improvement from 0.55 ± 0.34 at baseline to 0.24 ± 0.28 at 12 months. The previously treated group had no significant BCVA changes. CMT significantly decreased in both groups: from 295.3 ± 105.2 µm to 207.3 ± 63.0 µm in the treatment-naïve group, and from 196.1 ± 62.0 µm to 147.2 ± 50.1 µm in the previously treated group. Dry macula rates were high: 83% at 3 months and 83% at 12 months in the treatment-naïve group, and 67% at 3 months and 89% at 12 months in the previously treated group. No adverse events were reported. Conclusions: These findings indicate that RBZ-BS is an effective and safe treatment for mCNV, particularly in treatment-naïve patients. The use of RBZ-BS offers a cost-effective alternative to original ranibizumab, reducing financial burdens while maintaining high therapeutic efficacy. Further studies with larger sample sizes and longer follow-up periods are needed to confirm these results and evaluate long-term outcomes and cost-effectiveness.

[Relationship between birth month and corneal radius or axial length].

PURPOSE: Hyperopia prevalence is higher in children born in the autumn. This study attempted to detect whether corneal curvature or axial length are related to this phenomenon. METHODS: Using data from a total of 4056 cataract patients aged 40 and over from three medical facilities, corneal radius and axial length, measured to determine the intraocular lens power needed for cataract surgery, were reviewed. Mean corneal radius and mean axial length were calculated for each birth month. The means were then graphically analyzed to determine the relationship of corneal radius or axial length with birth month. RESULTS: No correlation was noted between axial length and birth month. However, a correlation between corneal radius and birth month was observed in each of the three facilities. Specifically, subjects born from October through December tended to have larger corneal radii. Numerically, the corneal radius showed a statistical relationship in terms of birth month (p < 0.001, ANOVA), while the axial length showed no relationship (p = 0.907, ANOVA). CONCLUSION: A statistically meaningful relationship between corneal curvature and birth month was detected. Corneal development might be affected by seasonal daylight variations in infancy, thus contributing to the occurrence of hyperopia.

Practical treatment options for persistent central serous chorioretinopathy and early visual and anatomical outcomes.

PURPOSE: Persistent central serous chorioretinopathy (pCSC) may be treated by laser photocoagulation (PC), selective retina therapy (SRT), or photodynamic therapy (PDT). We conducted retrospective analyses regarding the choice of therapy for pCSC in the best clinical practice and the outcomes of these modalities. STUDY DESIGN: A retrospective interventional study. METHODS: The records of 71 eyes of 68 treatment naïve pCSC cases who underwent PC, SRT, or PDT were reviewed. First, the baseline clinical parameters were evaluated to find significant factors associated with the choice of treatment option. Second, the 3 months' visual and anatomical outcomes of each modality were assessed. RESULTS: The PC, SRT, and PDT groups included 7, 22, and 42 eyes, respectively. The leakage pattern in fluorescein angiography (FA) was significantly associated with the choice of treatment (p<0.005). The dry macula ratio at 3 months post-treatment was 29%, 59%, and 81% in the PC, SRT, and PDT groups, respectively, which significantly differed among the groups (p<0.01). The best-corrected visual acuities tended to be improved after the treatments in all groups. Central choroidal thickness (CCT) was significantly decreased in all groups (p<0.05, p<0.01, and p<0.00001, in PC, SRT, and PDT groups, respectively). Logistic regression analysis for dry macula revealed that SRT (p<0.05), PDT (p<0.05), and the changes in CCT (p<0.01)were the significant association factors. CONCLUSION: The leakage pattern in FA was associated with the choice of treatment option for pCSC. PDT achieved a significantly higher dry macula ratio than PC, 3 months after the treatment.

Comparative Treatment Study on Macular Edema Secondary to Branch Retinal Vein Occlusion by Intravitreal Ranibizumab with and without Selective Retina Therapy.

The purpose of this study was to compare the safety and efficacy of selective retina therapy (SRT) combined with the intravitreal injection of ranibizumab (IVR) in patients with macular edema (ME) secondary to branch retinal vein occlusion (BRVO). This trial was a 12-month single-center, randomized, single-masked prospective study. Eligible patients were randomized (1:1) to IVR and SRT (IVR + SRT group), or IVR and sham SRT (IVR + sham group). After the initial IVR, all participants received ME resolution criteria-driven pro re nata treatment. SRT or sham SRT was always applied one day after IVR. The primary outcome measure of this study was the mean change in central macular thickness (CMT) from baseline, and the secondary outcome measures were the mean change in visual acuity from baseline and the number of IVR treatments at a 52-week follow-up. Thirteen patients were in the IVR + SRT group, and 11 were in the IVR + sham group. Compared to the baseline, mean CMT and BCVA improved significantly after 52 weeks in both groups, with no significant difference between the two groups. The mean number of IVR was 2.85 ± 1.52 in the IVR + SRT group and 4.73 ± 2.33 in the IVR + sham group at the 52-week follow-up, with a significant difference between the two groups (p < 0.05). IVR combined with SRT may significantly decrease the number of IVR treatments while maintaining the visual and anatomical improvement effect of IVR monotherapy.

A case of persistent hypotony following 23-gauge vitrectomy.

We report here a case in which ciliary detachment related to the preparation of a scleral wound was suspected as the cause of persistent hypotony following 23-gauge vitrectomy for proliferative diabetic retinopathy. Ultrasound biomicroscopy (UBM) was performed following injection of a viscoelastic substance into the anterior chamber to carefully investigate the treatment and cause of persistent hypotony. Deepening the anterior chamber by means of the viscoelastic substance enabled UBM identification of ciliary detachment that had not been detected in the shallow anterior chamber. The extent of ciliary detachment was approximately 8 degrees; however, the detachment could not be seen on gonioscopy. UBM showed no continuity between the anterior chamber and choroid, with findings suggesting that the two structures had been split by posterior traction. The ciliary detachment site was the same site at which a three-port system had been prepared. One advantage of a 23-gauge system is that few complications are associated with the insertion and retraction of instruments. However, the difference in level between the cannula and trocar may result in ciliary detachment even if no resistance is felt when the trocar is inserted.

Fundus white spots associated with graft-versus-host disease in the remission phase of acute myeloid leukemia.

Purpose: To report a case of fundus white spots associated with graft-versus-host disease (GVHD) during the remission phase of acute myelogenous leukemia (AML). Observations: A 60-year-old woman was diagnosed with AML 7 months earlier, and after 3 months of chemotherapy, she underwent bone marrow transplantation 2 months earlier and was in remission. When she first came to our department with the chief complaint of persistent bilateral floaters before she developed AML, she had a skin rash caused by GVHD that had been diagnosed 4 days earlier, and the fundi of both eyes showed multiple white spots in the deep retinal layers. One month later, the GVHD skin rash had resolved with topical steroid treatment, and the fundus white spots had mostly disappeared. Fifteen months after the initial visit, the fundus white spots had completely disappeared, with remaining hypofluorescent dots on fundus autofluorescence. Her best-corrected visual acuity was 1.2 in each eye at the first visit and remained at 1.0 in the right eye and 1.2 in the left eye at the final visit 15 months later. Conclusions and importance: Fundus white spots may occur in the early phase of GVHD, causing focal retinal pigment epithelium atrophy after resolution.

Early anatomical changes and association with photodynamic therapy induced acute exudative maculopathy in patients with macular diseases.

The purpose of this study was to investigate the occurrence rate and predictors of photodynamic therapy (PDT) induced acute exudative maculopathy (PAEM). This retrospective study included 39 eyes of 39 patients (32 males and 7 females), who were treated with initial PDT. PAEM was defined as an increase in central retinal thickness (CRT) of 15% or more measured by OCT on day 3 after PDT compared with baseline. Sixteen of 39 eyes (41%) were classified in the PAEM+ group. CRT and central choroidal thickness (CCT) were significantly increased at 3 days in the PAEM+ group and significantly decreased at 1 month after PDT in the PAEM- group. In a multiple comparison, neovascular age-related macular degeneration (nAMD) had a significantly higher incidence of PAEM compared to polypoidal choroidal vasculopathy (PCV) and central serous chorioretinopathy (CSC). The incidence of PAEM was lower in PCV and CSC, and higher in nAMD. BCVA at 1 month was significantly worse in the PAEM group, which may be related to visual prognosis after PDT. Since both CRT and CCT decrease at 1 month, the detection of PAEM needs to be assessed a few days after PDT.

Progression of cataracts following photodynamic therapy combined with intravitreous triamcinolone injection in cases of age-related macular degeneration.

BACKGROUND: To present long-term data on the progression of cataracts following photodynamic therapy (PDT) combined with 4 mg intravitreal triamcinolone acetonide (IVTA) for age-related macular degeneration (AMD). METHODS: Fifty-seven phakic eyes of 56 patients underwent the treatment between October 2004 and November 2006. The follow-up period ranged from 12 to 38 months with 3 months interval of observation and repeated treatment at recurrence. RESULTS: Cataract progression was noted in 40 eyes 5-21 months after treatment, consisting of 4 eyes between 3 and < 6 months after treatment, 22 eyes between 6 and < 12 months, 8 eyes between 12 and < 18 months, and 6 eyes between 18 and < 24 months. The percentage of the eyes with cataract progression began to decrease 5 months after treatment and, occurred most frequently during the period from 6 months to 12 months after treatment. There was no significant difference in age, follow-up period, or the frequency of the treatment between the cataract progression group and the non progression group. Twenty four eyes underwent surgery 10-31 months after treatment, showing significant improvement in visual acuity. CONCLUSIONS: This study showed high incidence of cataract during a long-term follow-up after PDT combined with IVTA and significant reduction of visual acuity due to cataract.

Factors affecting resolution of subretinal fluid after selective retina therapy for central serous chorioretinopathy.

The purpose of this study was to investigate the factors of clinical outcome of selective retina therapy (SRT) for central serous chorioretinopathy (CSC). This retrospective study included 77 eyes of 77 patients, who were treated with SRT for CSC and observed at least 6 months after the treatment. SRT laser (527 nm, 1.7 µs, 100 Hz) was used for treatment. The mean best-corrected visual acuity (logMAR), central macular thickness (CMT) and central choroidal thickness were changed from baseline to at 6-months follow-up with significant difference. The multivariate analyses found that the rate of change (reduction) in CMT was associated with focal leakage type on fluorescein angiography (FA) (p = 0.03, coefficient 15.26, 95% confidence interval 1.72-28.79) and larger baseline CMT (p < 0.01, coefficient - 0.13, 95% confidence interval - 0.13 to - 0.05). Complete resolution of subretinal fluid was associated with nonsmoking history (p = 0.03, odds ratio 0.276, 95% confidence interval 0.086-0.887) and focal leakage type on FA (p < 0.01, odds ratio 0.136, 95% confidence interval 0.042-0.437). These results may be useful for predicting the therapeutic effectiveness of SRT.
