RESUMEN
PURPOSE: In individuals aged >50 years, age-related macular degeneration (AMD) is the leading cause of irreversible blindness. Intravitreal injections of antivascular endothelial growth factor (VEGF) agents (bevacizumab, ranibizumab, and aflibercept) show good efficacy and similar incidences of systemic adverse events (SAEs). However, comparative studies between agents are limited. Our study aimed to compare the real-world SAE risks of bevacizumab, ranibizumab, and aflibercept users. METHODS: This retrospective cohort study identified new bevacizumab, ranibizumab, and aflibercept users in a multi-institutional database in Taiwan between 2014 and 2019. Inverse probability of treatment weights (IPTW) with propensity scores was conducted to achieve homogeneity among groups. The Fine and Gray model was utilized to estimate the subdistribution hazard ratio and 95% confidence interval. RESULTS: This study included 701 bevacizumab, 463 ranibizumab, and 984 aflibercept users. After IPTW, all covariates were well-balanced. All three anti-VEGF agents had a low and comparable number per 100 person-years of major adverse cardiac events, heart failure, thromboembolic events, major bleeding, all-cause admission, and all-cause death (all P > 0.05). No significant differences in long-term change of systolic and diastolic blood pressure, low-density lipoprotein, estimated glomerular filtration rate, and alanine transaminase (all P for interaction > 0.05) were observed among groups. CONCLUSION: Bevacizumab, ranibizumab, and aflibercept had a good systemic safety profile in this study. All groups showed a low and similar SAE risk and no differences in their long-term change of laboratory data. Therefore, these anti-VEGF agents could be prescribed safely to patients with AMD.
RESUMEN
Retinal vasoproliferative tumors (RVPTs) are rare benign retinal lesions typically located in the inferotemporal peripheral retina. Several treatment options exist for the management of RVPTs, but no consensus has been proposed. There are only a few reports on the use of anti-vascular endothelial growth factor with bevacizumab to treat exudative or neovascular retinal changes secondary to RVPTs. This report describes a 68-year-old female with a history of systemic hypertension that presented with a 2-week history of gradual loss of visual acuity in the right eye. Fundoscopic examination showed a RVPTs with atypical location that had a favorable response to two-intravitreal aflibercept injections 1 month apart, with resulting subretinal fluid absorption and tumor regression.
RESUMEN
This retrospective cohort study aimed to assess the systemic effects of three commonly available anti-vascular endothelial growth factor intravitreal injections in patients with diabetes, using data taken from a multi-institutional database in Taiwan. Patient data were sourced from the multi-institutional Chang Gung Research Database. Participants were divided into groups based on treatment with bevacizumab, ranibizumab, or aflibercept. Baseline characteristics were matched among the groups by the inverse probability of treatment weighting. The incidence rate of outcome events was calculated as the number of events divided by 100 person-years of follow-up. The cumulative incidence function was used to estimate the incidence rate of the outcome events among groups. The incidence of ischemic stroke was higher in the ranibizumab group than the bevacizumab and aflibercept groups (1.65, 0.92, and 0.61 per 100 person-years, respectively). The incidence of major adverse lower-limb events was higher in the bevacizumab group (2.95), followed by ranibizumab (2.00) and aflibercept (0.74). Major bleeding was relatively higher in bevacizumab (12.1) compared to ranibizumab (4.3) and aflibercept (3.8). All-cause death was higher for both bevacizumab (3.26) and aflibercept (2.61) when compared to ranibizumab (0.55), and all-cause admission was found to be highest with bevacizumab (58.6), followed by aflibercept (30.2), and ranibizumab (27.6). The bevacizumab group demonstrated a greater decrease in glycated hemoglobin compared to the baseline level (-0.33%). However, a few differences in the clinical condition between the groups were still observed after matching. In conclusion, this study suggests that different anti-vascular endothelial growth factor agents may be associated with various and differing systemic adverse events. The differences might also be attributed to differences in patient characteristics and clinical status.
RESUMEN
INTRODUCTION: Intravitreal dexamethasone and anti-vascular endothelial growth factor (anti-VEGF) medications have revolutionized ocular disease management and favorable ocular safety profiles, but few studies have compared their systemic adverse events (SAEs). This study investigated the SAEs of intravitreal dexamethasone and anti-VEGFs by using real-world data. METHODS: This retrospective cohort study sourced medical records from the largest multi-institutional database in Taiwan. Patients who received intravitreal dexamethasone (n = 137) or anti-VEGFs (n = 10,345) between 2014 and 2019 were enrolled. Propensity score matching was performed to achieve homogeneity between the two groups. Subdistribution hazard ratios (SHRs) and 95% confidence intervals (CIs) were calculated using the Fine-Gray model. Systemic as well as ocular clinical events and systemic biomarkers after 1-year follow-up were compared. RESULTS: Both groups demonstrated comparable risks of major cardiac adverse events (SHR 1.57, 95% CI 0.29-8.55), heart failure (SHR 0.62, 95% CI 0.07-5.33), major bleeding (SHR 0.23, 95% CI 0.03-1.77), all-cause admission (SHR 0.73, 95% CI 0.41-1.30), and all-cause death (SHR 2.11, 95% CI 0.35-12.71). There were no significant differences in longitudinal changes in systolic and diastolic blood pressure, glycated hemoglobin, low-density lipoprotein, estimated glomerular filtration rate, or alanine aminotransferase between the groups. Both groups had a similar incidence of cataract surgery. Although the dexamethasone group exhibited a relatively high prevalence of antiglaucomatous medication use, there was not a significantly higher incidence of glaucoma surgery. CONCLUSION: Intravitreal dexamethasone and anti-VEGF medications had comparable systemic safety profiles in our study. Both drugs represent efficacious and safe therapies for ocular diseases.
RESUMEN
The aim of this review is to identify the common characteristics and prognoses of different subtypes of neovascular age-related macular degeneration (nAMD). We also propose recommendations on how to tailor treatments to the subtype of neovessels to optimise patient outcomes. The authors, selected members of the Vision Academy, met to discuss treatment outcomes in nAMD according to macular neovascularisation (MNV) subtypes, using evidence from a literature search conducted on the PubMed database (cut-off date: March 2019). This review article summarises the recommendations of the Vision Academy on how the characterisation of MNV subtypes can optimise treatment outcomes in nAMD. The identification of MNV subtypes has been facilitated by the advent of multimodal imaging. Findings from fluorescein angiography, indocyanine green angiography and spectral-domain optical coherence tomography collectively help refine and standardise the determination of the MNV subtype. To date, three subtypes have been described in the literature and have specific characteristics, as identified by imaging. Type 1 MNV is associated with better long-term outcomes but usually requires more intense anti-vascular endothelial growth factor dosing. Type 2 MNV typically responds quickly to treatment but is more prone to the development of fibrotic scars, which may be associated with poorer outcomes. Type 3 MNV tends to be highly sensitive to anti-vascular endothelial growth factor treatment but may be associated with a higher incidence of outer retinal atrophy, compared with other subtypes. Accurately assessing the MNV subtype provides information on prognosis and helps to optimise the management of patients with nAMD.

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

Neovascular age-related macular degeneration (nAMD) is a leading cause of irreversible vision loss. The present consensus provides suggestions on diagnosis, evaluation, treatment, and follow-up strategies for nAMD from a panel of 11 practicing ophthalmologists. The experts suggest that the baseline visit for nAMD management should include a comprehensive ophthalmologic examination via a multimodal approach consisting of visual and anatomical evaluation. Patients diagnosed with nAMD should be subjected to treatment with the goal of maintaining visual function while diminishing anatomical disease activity and minimizing treatment burden. Currently, anti-VEGF therapy is the main treatment strategy for nAMD, and evaluation involving comprehensive ophthalmologic examination within 1 month of completion of the loading phase comprising three monthly injections is recommended to guide subsequent management. Either a treat-and-extend or pro re nata regimen can be considered for the maintenance phase of anti-VEGF therapy, and the regimen should be chosen and adjusted according to disease activity, reimbursement criteria, financial burden, and patient preferences. In the event of inactive nAMD or poor treatment outcomes, after thorough evaluation and patient education, anti-VEGF therapy may be stopped. The consensus provides practical nAMD management guidelines for ophthalmologists and fellow healthcare professionals.

To investigate the association between clinical features of chronic central serous chorioretinopathy (CSC) and subsequent development of polypoidal choroidal vasculopathy (PCV). Characteristics and treatment response of PCV secondary to CSC were described. This retrospective observational study included 18 patients with chronic CSC (18 eyes) with subsequent PCV and 36 controls (36 eyes) with chronic CSC without PCV development during follow-up. Clinical features were compared between the two groups. A logistic regression model was used to evaluate the risk factor of PCV formation. Treatments for PCV included anti-vascular endothelial growth factor (VEGF) monotherapy, photodynamic therapy (PDT), or PDT and anti-VEGF combination treatment. Subretinal fluid on optical coherence tomography images were assessed after treatments. Significant between-group differences were observed in best-corrected visual acuity after disease resolution and presence of pachyvessels (P = .001 and P = .003, respectively). The presence of pachyvessels in chronic CSC was associated with subsequent PCV (odds ratio = 6.00; 95% CI, 1.74-20.68; P = .005). CSC recurrence and subfoveal choroidal thickness (SFCT) were not significantly associated with subsequent PCV development (P = .393 and P = .911, respectively). The mean age of PCV diagnosis was 51 years, and the mean time from CSC diagnosis to PCV confirmation was 77.8 months. The mean (range) SFCT of PCV was 327.7 (134-599) µm. Nine patients received anti-VEGF monotherapy and 5 had disease remission. Four patients received PDT and anti-VEGF combination treatment and all of the 4 had disease remission. In chronic CSC, pachyvessel characteristics are associated with subsequent PCV development. This result will assist clinicians to evaluate CSC in clinical practice and provide insights into the pathogenesis of PCV.

Importance: The 2-year efficacy and safety of combination therapy of ranibizumab administered together with verteporfin photodynamic therapy (vPDT) compared with ranibizumab monotherapy in participants with polypoidal choroidal vasculopathy (PCV) are unclear. Objective: To compare treatment outcomes of ranibizumab, 0.5 mg, plus prompt vPDT combination therapy with ranibizumab, 0.5 mg, monotherapy in participants with PCV for 24 months. Design, Setting, and Participants: This 24-month, phase IV, double-masked, multicenter, randomized clinical trial (EVEREST II) was conducted among Asian participants from August 7, 2013, to March 2, 2017, with symptomatic macular PCV confirmed using indocyanine green angiography. Interventions: Participants (N = 322) were randomized 1:1 to ranibizumab, 0.5 mg, plus vPDT (combination therapy group; n = 168) or ranibizumab, 0.5 mg, plus sham PDT (monotherapy group; n = 154). All participants received 3 consecutive monthly ranibizumab injections, followed by a pro re nata regimen. Participants also received vPDT (combination group) or sham PDT (monotherapy group) on day 1, followed by a pro re nata regimen based on the presence of active polypoidal lesions. Main Outcomes and Measures: Evaluation of combination therapy vs monotherapy at 24 months in key clinical outcomes, treatment exposure, and safety. Polypoidal lesion regression was defined as the absence of indocyanine green hyperfluorescence of polypoidal lesions. Results: Among 322 participants (mean [SD] age, 68.1 [8.8] years; 225 [69.9%] male), the adjusted mean best-corrected visual acuity (BCVA) gains at month 24 were 9.6 letters in the combination therapy group and 5.5 letters in the monotherapy group (mean difference, 4.1 letters; 95% CI, 1.0-7.2 letters; P = .005), demonstrating that combination therapy was superior to monotherapy by the BCVA change from baseline to month 24. Combination therapy was superior to monotherapy in terms of complete polypoidal lesion regression at month 24 (81 of 143 [56.6%] vs 23 of 86 [26.7%] participants; P < .001). Participants in the combination group received fewer ranibizumab injections (median, 6.0 [interquartile range (IQR), 4.0-11.0]) than the monotherapy group (median, 12.0 [IQR, 7.0-17.0]) up to month 24. The combination group required a median of 2.0 (IQR, 1.0-3.0) vPDT treatments for 24 months, with 75 of 168 participants (44.6%) requiring only 1 vPDT treatment. Conclusions and Relevance: The 24-month data findings confirm that ranibizumab therapy, given as monotherapy or in combination with vPDT, is efficacious and safe for treatment of PCV. Combination therapy with vPDT added to ranibizumab achieved superior BCVA gain, increased odds of complete polypoidal lesion regression, and fewer treatment episodes compared with ranibizumab monotherapy.

Diabetic macular edema (DME) is the most common cause of vision loss among patients with diabetes mellitus (DM), rendering it an important growing challenge in ophthalmology. In the past decades, the management strategies for DME had a few paradigm shifts, and the advent of an expanding number of anti-vascular endothelial growth factor (VEGF) agents also calls for an in-depth examination of the currently available evidence. This article was composed with the intention to provide recommendations for practicing clinicians to improve the management and, through it the outcomes of DME. Drawing from current guideline recommendations, clinical trial findings and local clinical experiences, these consensus recommendations for the management of DME were formed by an expert panel through iterations of discussion and voting. First, the treatment goal of DME is to achieve best visual outcome with edema improvement while minimizing treatment burden. Second, anti-VEGF therapy should be considered as the first-line treatment for patients with center-involving DME causing vision loss. Baseline visual acuity (VA) and central subfield thickness (CST) should be taken into consideration when choosing anti-VEGF agents. Third, early intensive anti-VEGF therapy (at least 3 monthly doses) is important for better patients' VA and anatomical improvement. In non-responders who have already been treated with 3-5 injections of anti-VEGF agents, it is reasonable to switch to other modalities, such as steroids. Finally, for the follow-up phase, fixed or individualized dosing should be considered based on VA and OCT.

Polypoidal choroidal vasculopathy (PCV) is a prevalent retinal disease predominantly occurs in Asians that shares some similarities seen in neovascular age-related macular degeneration. Recent large multicenter clinical trials on intravitreal anti-vascular endothelial growth factor (VEGF) agents and photodynamic therapy (PDT) have shed lights on the management of PCV. The Taiwan National Health Insurance had granted limited anti-VEGF agents and PDT for patients with PCV after the approval of required data submission, especially fundus angiography, optical coherence tomography, and visual acuity. In order to best utilize these limited resources for the patients, an expert meeting was held to provide updated Taiwan consensus recommendations for the management of PCV, including initial therapy selection, assessment of treatment response, re-treatment/rescue treatment, and determination of treatment extension/follow-up schedule. An algorithm for treatment allocation under both initial and re-treatment setting was proposed. Further mechanistic and clinical studies are required to investigate the prognostic factors and optimal treatment protocols that will improve healthcare quality and reduce burden of disease and treatment for patients with PCV.

Mucopolysaccharidoses (MPS) is a group of lysosomal storage disorders that lead to accumulation of glycosaminoglycans (GAGs) in many tissues and organs, resulting in different clinical features. In this study, we conducted the manifestation changes of refractive error, corneal clouding, and intraocular pressure in two Taiwanese MPS VI patients with enzyme replacement therapy (ERT) initiated at the age of eight. In case 1, hyperopia was noted before and after ERT. Clinical observation showed no significant improvement in corneal clouding after ERT. In case 2, hyperopia was also noted initially before ERT and unable to be measured due to severe corneal opacity. Clinical observation showed no significant improvement in corneal clouding in after ERT, and the best-corrected visual acuity worsen and keratoplasty was needed in both eyes. Case 2 also had ocular hypertension and suspect MPS VI-related. However, due to severe corneal clouding, optic disc changes were hard to examine, and visual field was unable to be tested. Although some literature shows that ERT may be effective in preventing and/or clearing corneal stromal GAGs, accumulation and the timing of treatment initiation cloud be a clinical prognosis predictor; in this experience, no significant improvement of corneal clouding was observed in patients with MPS IV after ERT. Hyperopia and glaucoma were noted, and showed no changes after ERT. Severe corneal clouding can lead to difficulties in diagnosis and monitoring of hyperopia and glaucoma.
RESUMEN
BACKGROUND: Mucopolysaccharidoses (MPSs) are a group of rare lysosomal storage disorders characterized by the accumulation of glycosaminoglycans in various tissues and organs. Ocular problems that affect the cornea, trabecular meshwork, sclera, retina, and optic nerve are very common in these patients. However, there was limited literature focusing on comprehensive ocular findings in different types of MPS. METHODS: We retrospectively reviewed the clinical ophthalmologic features and electrodiagnostic results of 50 Taiwanese patients with a diagnosis of MPS (34 males and 16 females; age range, 1.1-34.9 years; nine with MPS I, 17 with MPS II, 17 with MPS IV, and seven with MPS VI). RESULTS: Among 44 patients with available data for visual acuity, 15 patients (34%) had a visual acuity of less than 0.5 (6/12) equivalent in their better eye, including 71% of those with MPS VI, 38% with MPS IV, 29% with MPS I, and 14% with MPS II. Severe corneal opacities existed in 57% of MPS VI patients and 11% of MPS I patients, compared with none for MPS II and MPS IV patients. Among 80 eyes with available data of refraction, 11 eyes (14%) had myopia (â¦-0.50 D), 55 eyes (69%) had hyperopia (â§0.50 D), and 55 eyes (69%) had high astigmatism (â§1.50 D). Ocular hypertension was found in 45% (28/62) of eyes. There were 16% (14/90), 11% (10/90), 13% (12/90), 31% (27/86), and 79% (30/38) of MPS eyes with lens opacities, optic disc swelling, optic disc cupped, retinopathy, and visual pathway dysfunction, respectively. Intraocular pressure was positively correlated with the severity of corneal opacity (p < 0.01). CONCLUSIONS: Ocular complications with significant reduction in visual acuity are common in MPS patients. Diagnostic problems may arise in these patients with severe corneal opacification, especially for those with MPS VI and MPS I.

We presented a rare case of a sole choroidal metastatic tumor from esophageal squamous cell carcinoma (ESCC) without other organ metastasis in Taiwan. A 43-year-old male with ESCC was referred for a 1-month history of decreased vision in his left eye. A 5.7 mm thick, yellow choroidal tumor occupied posterior pole, featured with pinpoint hyperfluorescence on angiography and subretinal fluid on optical coherence tomography. Positron emission tomography showed a singular hypermetabolic focus in the left eye. The tumor regressed with complete response and the vision preserved after radiation with total 57.60 gray applied by tomotherapy. The gastrointestinal system is the third most common metastatic origin in Taiwan while esophageal cancer metastasizing to choroid is rare. The discrepancy between the high prevalence of primary ESCC and the rareness of choroidal metastasis from ESCC is undetermined.

Diabetic macular oedema is the most common cause of diabetic retinopathy-induced vision loss. Efficacy of anti-vascular endothelial growth factor therapy in diabetic macular oedema has been demonstrated in randomized controlled trials. An Asian-specific guideline for diabetic macular oedema treatment is needed as patients in Asia tend to present with far more advanced disease than seen elsewhere in the world. Previous reviews of diabetic macular oedema management lacked a broader assessment of anti-vascular endothelial growth factor treatment choices and newer trials. Recent clinical trial data allow head-to-head comparisons between the different anti-vascular endothelial growth factor agents and treatment regimens. This review aims to summarize the clinical evidence related to various treatment regimens for clinicians, with a focus on anti-vascular endothelial growth factor therapies, and to provide guidance on the treatment of diabetic macular oedema in Asian patients.

Importance: Polypoidal choroidal vasculopathy (PCV) is a common subtype of exudative age-related macular degeneration among Asian individuals. To our knowledge, there are no large randomized clinical trials to evaluate intravitreal ranibizumab, with and without verteporfin photodynamic therapy (vPDT), for the treatment of PCV. Objective: To compare the efficacy and safety of combination therapy of ranibizumab and vPDT with ranibizumab monotherapy in PCV. Design, Setting, and Participants: A double-masked, multicenter randomized clinical trial of 322 Asian participants with symptomatic macular PCV confirmed by the Central Reading Center using indocyanine green angiography was conducted between August 7, 2013, and March 2, 2017. Interventions: Participants were randomized 1:1 to ranibizumab, 0.5 mg, and vPDT (n = 168; combination therapy group) or ranibizumab, 0.5 mg, and sham PDT (n = 154; monotherapy group). All participants received 3 consecutive monthly ranibizumab injections, followed by a pro re nata regimen. Participants also received vPDT/sham PDT on day 1, followed by a pro re nata regimen based on the presence of active polypoidal lesions. Main Outcomes and Measures: Step 1 assessed whether combination therapy was noninferior (5-letter margin) to monotherapy for change in best-corrected visual acuity from baseline and superior in complete polyp regression. If noninferiority was established, step 2 assessed whether combination therapy was superior to monotherapy measured by best-corrected visual acuity change at month 12. Results: Baseline demographics of the 322 participants were comparable between the treatment groups. Mean (SD) age of the patients was 68.1 (8.8) years, and overall, 69.9% of the patients were men. At baseline, the overall mean best-corrected visual acuity and mean central subfield thickness were 61.1 letters and 413.3 µm, respectively. At 12 months, mean improvement from baseline was 8.3 letters with combination therapy vs 5.1 letters with monotherapy (mean difference, 3.2 letters; 95% CI, 0.4-6.1), indicating that combination therapy met the predefined criterion for noninferiority as well as being superior to monotherapy (P = .01). Combination therapy was also superior to monotherapy in achieving complete polyp regression at month 12 (69.3% vs 34.7%; P < .001). Over 12 months, the combination therapy group received a median of 4.0 ranibizumab injections compared with 7.0 in the monotherapy group. Vitreous hemorrhage was the only ocular serious adverse event (combination therapy group, 1 [0.6%]; monotherapy group, 3 [2.0%]). Conclusions and Relevance: After 12 months, combination therapy of ranibizumab plus vPDT was not only noninferior but also superior to ranibizumab monotherapy in best-corrected visual acuity and superior in complete polyp regression while requiring fewer injections. Combination therapy should be considered for eyes with PCV. Trial Registration: clinicaltrials.gov Identifier: NCT01846273.

Incontinentia pigmenti (IP) is a rare disease with multisystemic anomalies, which commonly presents just after birth. Here, we report a rare case of IP patient with vitreous hemorrhage in school-age children. Therefore, physicians have to be alert and evaluate IP patients at all ages. Regular ophthalmic follow-up is necessary, and fluorescein angiography should be performed if peripheral ischemia or neovascularization is suspected. The effect of peripheral laser ablation on peripheral retinal nonperfusion is not clear and merits further study.

PURPOSE: To evaluate the real-world experience with half-time photodynamic therapy (PDT) versus half-dose PDT for chronic central serous chorioretinopathy (CSC). METHODS: This multicenter retrospective study enrolled patients who received half-time PDT (with irradiation time shortened to 42 s) or half-dose PDT (with the dosage of verteporfin reduced to 3 mg/m2) for chronic CSC and who were followed up for â§12 months. The success rate, central subfield retinal thickness (CST), and best-corrected visual acuity (BCVA) were documented in each group of patients. RESULTS: A total of 53 eyes from 49 patients were enrolled in this study. Seventeen eyes (15 patients) received half-time PDT and 36 eyes (34 patients) received half-dose PDT. The success rates in both groups were similar at 12 months (94.1% vs. 94.4%; P = 0.543). The mean CST at 1, 6, 12 months decreased significantly when compared with the baseline in both groups (all P < 0.001). The BCVA significantly improved at 6 and 12 months in both groups (all P < 0.05). There were no significant differences in changes of BCVA and changes of CST between the 2 groups at any time point. CONCLUSIONS: Half-time PDT is a feasible treatment for chronic CSC. It has success rates similar to half-dose PDT at 12 months. There were no significant differences in changes of BCVA and changes of CST between the 2 groups at 1, 6, and 12 months after treatment.
