Abstract
Choroidal neovascularization (CNV) affects 64-75% of eyes with punctate inner choroidopathy (PIC). Although anti-VEGF agents are considered first-line therapy, there is controversy regarding other modalities, such as immunosuppression. We performed a systematic review of individual participant data (IPD) and generated a dataset of 278 eyes with PIC-related CNV from 45 studies. Forty-two percent presented with moderate visual loss (MVL) or worse. Four different treatment modalities (anti-VEGF, photodynamic therapy, local immunosuppression, and systemic immunosuppression) and most combinations among them were represented. Anti-VEGF injections decreased the likelihood of MVL (Odds Ratio 0.3, p = .027), an effect moderated by presenting visual acuity and patient age. Eyes receiving more than 3 injections were more likely to receive additional therapeutic modalities. Increasing number of modalities was associated with longer follow-up time and did not improve vision. The beneficial effect of anti-VEGF injections persisted when controlling for presenting visual acuity and follow-up time.

Abstract
INTRODUCTION In the past several years, there have been numerous advances in pharmacotherapeutics for the management of uveitis and other ocular inflammatory diseases, including newer therapeutic agents and ocular drug delivery systems. One of the most attractive modes of drug delivery is the intravitreal route since it has proven to be safe and efficacious and prevents unwanted systemic adverse events related to the agent. AREAS COVERED In this review, intravitreal delivery of various pharmacotherapeutic agents for noninfectious uveitis has been described. An extensive review of the literature was performed using specific keywords on the PubMed database to identify clinical studies employing various pharmacotherapeutic agents with intravitreal drug delivery for noninfectious uveitis. The mode of action, safety, efficacy, and tolerability of these drugs have also been elucidated. EXPERT OPINION Several agents, including biologic response modifier agents, have been found to be safe and efficacious for various indications of uveitis, such as cystoid macular edema, active uveitis, and other conditions such as retinal vasculitis and vitreous haze. The use of intravitreal biological therapies, especially infliximab, has been fraught with potential safety signals such as photoreceptor toxicity. However, pharmacotherapeutic agents such as corticosteroids and anti-vascular endothelial growth factor agents are now widely used in the clinical management of uveitis and its complications.

Abstract
Objective To investigate the clinical study of intravitreal injection of anti-VEGF drugs combined with intravitreal injection of tretinoin for the treatment of Coats disease. Methods The medical records of 90 patients (120 eyes) with Coats disease admitted to our hospital from April 2010 to June 2021 were selected as retrospective study subjects and divided into control and treatment groups according to the numerical table method. There were 45 cases and 60 eyes in each group. Among them, intravitreal tretinoin drug was injected into the control group, and anti-VEGF drug was injected into the vitreous sclera of the treatment group on the basis of the control group. Results Before treatment, the differences in visual acuity changes between the two groups were not statistically significant (P > 0.05). After treatment, the light perception, manipulation, and indexes of both groups were significantly improved, and the treatment group was significantly better than the control group. This difference was statistically significant (P < 0.05) for statistical study comparison. The effective rate of 95.56% in the treatment group was significantly higher than that of 86.67% in the control group, and the complication rate was significantly lower than that of the control group, with statistically significant differences (P < 0.05). Conclusion Intravitreal injection of anti-VEGF drugs combined with tretinoin injection can significantly improve the clinical efficacy of patients with Coats disease and improve visual acuity and central retinal thickness, which has certain reference value for the clinical treatment of Coats disease.

Abstract
Inflammatory choroidal neovascularization (iCNV) is a rare complication of uveitis but is a major cause of vision compromise in affected patients. Fluorescein angiography (FA) has been the gold standard for diagnosis. However, it is an invasive modality and when used alone, it might be difficult to distinguish iCNV from inflammatory lesions. Optical coherence tomography (OCT) is a noninvasive and rapid imaging modality that can provide additional features to diagnose iCNV. OCT angiography (OCTA) uses intrinsic motion contrast to visualize flow and is useful to distinguish iCNV from inflammatory lesions. However, its role in evaluating iCNV activity and treatment response is still unclear and more studies are required to reach consensus. In conclusion, the use of data from multimodal imaging is necessary to identify and promptly treat iCNV, thus preserving patient vision.

Abstract
ABSTRACT Uveitic macular edema is a significant cause of visual impairment in most uveitis types. Treatment options of uveitis have advanced remarkably in recent years. Up to now, corticosteroids remain the mainstay of treatment. Nonsteroidal immunomodulators, and recently the biologic agents, which can reinforce efficacy and enable discontinuation or reduction of steroids to maintenance doses, are becoming increasingly popular in the management of uveitic macular edema. Several medications can be used in intraocular delivery and more and more sustained releasing implants are being developed. This review will briefly focus on the review of local therapy for the management of cystoid macular edema in uveitis, as many of these novel approaches are currently being evaluated in clinical trials.

Abstract
PURPOSE To compare the sensitivity and specificity of identifying and evaluating the choroidal neovascularisation (CNV) in punctate inner choroidopathy (PIC) by optical coherence tomography angiography (OCTA) versus dye angiography. METHODS Consecutive patients diagnosed with PIC were enrolled in this study from June 2016 to December 2019. During the same visit, each patient underwent comprehensive ophthalmological and multimodal imaging examinations. The diagnostic accuracy of different modalities was evaluated. RESULTS The study included 160 affected eyes from 123 patients. Ninety-five eyes (59.38%) were identified with secondary CNV by multimodal imaging. The sensitivity and specificity for CNV detection with OCTA alone were 89.47% and 98.46%, respectively. OCTA also provided the morphology of CNV to determine the activity of CNV with a sensitivity of 86.67% and a specificity of 94.29%. CONCLUSIONS In this study, we investigated the utility of OCTA in the diagnosis and evaluation of patients with CNV secondary to PIC. Compared with dye angiography, OCTA show convincing diagnosis accuracy. Although OCTA has several limitations and is not sufficient to replace dye angiography in clinical practice, it can provide clinicians with a non-invasive way to monitor patients with CNV secondary to PIC and guide treatment decisions.

Abstract
PURPOSE To evaluate the efficacy of corticosteroid-sparing immunomodulatory therapy (IMT) in patients with recurrent and/or sight-threatening central multifocal choroiditis (MFC). METHODS This was a retrospective cohort study in a tertiary uveitis centre including all patients with MFC who have been treated with IMT for at least 12 months. Clinical data and imaging results were collected regarding the period prior to the start of IMT and at 3, 6, 12 and - where available - 24 months after the start of IMT. Main outcome measure was the number of annual recurrences of choroiditis with or without active choroidal neovascularization before and after the start of IMT. Secondary outcomes were the percentage of patients with (steroid-free) remission and the median time between the start of IMT and (steroid-free) remission. RESULTS Thirty-two patients (39 eyes) were included. At the start of IMT, none of the patients were in (steroid-free) remission. At 24 months, the probability of achieving remission and steroid-free remission was 88,5% and 50%, respectively. The median time to achieve remission and steroid-free remission was 21 and 83 weeks, respectively. In 17 patients (20 eyes) with available clinical data and imaging results for ≥ 12 months prior to the start of IMT, the mean number of recurrences/year decreased significantly from 1.40 ± 0.81 at baseline to 0.49 ± 0.47 (p = 0.001) after the start of IMT. CONCLUSIONS Preventive therapy with IMT should be considered in patients with recurrent and/or sight-threatening MFC to decrease the number of recurrences/year and to increase the prospects of achieving either remission or steroid-free remission.

Abstract
BACKGROUND To study the effect of anti-VEGFs in proliferative MacTel 2 METHODS: Sixty-four eyes of 51 patients of MacTel 2 with subretinal neovascular membrane (SRNVM) undergoing intravitreal anti-VEGF monotherapy at our institution between January 2015 and December 2018 were evaluated for visual acuity, central macular thickness (CMT) and total macular volume (TMV) using optical coherence tomography (OCT). Repeat investigations were performed at the final follow-up. RESULTS Location of SRNVM was foveal (F) in 65.6% eyes and extrafoveal (EF) in 34.4% eyes. Both CMT and TMV were lower significantly at baseline in EF-SRNVM. Fifty-six eyes received intravitreal bevacizumab and 8 eyes received ranibizumab. Average 2.14 ± 1.21 injections (range, 1-6) were administered. After a mean follow-up duration of 16.01 ± 12.96 months, the final visual acuity (VA) improved in 35.9% eyes, reduced in 28.1% and remained unchanged in 35.9% eyes. Significant improvement of VA was seen in F-SRNVM; however, overall, there was no significant improvement in visual acuity. Significant reduction in CMT was seen in F-SRNVM from 391.73 ± 152.45 μm to 293.33 ± 114.77 μm (p < 0.05) while EF-SRNVM did not show significant reduction. Total macular volume overall changed significantly from 8.79 ± 1.69 to 8.05 ± 1.27 (p < 0.05) and individually in F- and EF-SRNVM (p < 0.05). Intravitreal bevacizumab and ranibizumab monotherapy both had similar efficacy. CONCLUSIONS Anti-VEGF agents can be successfully used to treat proliferative MacTels. Macular volume measurement on OCT may be a useful parameter for evaluating EF-SRNVM and as a prognostic marker of management outcomes.

Abstract
Purpose To evaluate the safety and tolerability of a microsphere thermo-responsive hydrogel drug delivery system (DDS) loaded with aflibercept in a nonhuman primate model. Methods A sterile 50 µL of aflibercept-loaded microsphere thermo-responsive hydrogel-DDS (aflibercept-DDS) was injected intravitreally into the right eye of 10 healthy rhesus macaques. A complete ophthalmic examination, intraocular pressure (IOP) measurement, fundus photography, spectral-domain optical coherence tomography (SD-OCT), and electroretinogram were performed monthly for 6 months. One macaque was euthanized monthly, and the enucleated eyes were submitted for measurement of bioactive aflibercept concentrations. Four eyes were submitted for histopathology. Results Injected aflibercept-DDS was visualized in the vitreous until 6 months postinjection. No abnormalities were observed in the anterior segment, and IOP remained within normal range during the study period. A small number of cells were observed in the vitreous of some macaques, but otherwise the remainder of the posterior segment examination was normal. No significant changes in retinal architecture or function as assessed by SD-OCT and histology or full-field electroretinography, respectively, were observed. A mild, focal foreign body reaction around the injectate was observed with histology at 6 months postinjection. A mean of 2.1 ng/µL of aflibercept was measured in the vitreous. Conclusions Intravitreally injected aflibercept-DDS achieved controlled, sustained release of aflibercept with no adverse effects for up to 6 months in the eyes of healthy rhesus macaques. Translational Relevance Aflibercept-DDS may be a more effective method to deliver bioactive antivascular endothelial growth factor agents than current practice by reducing the frequency of intravitreal injections and providing controlled drug release.

Abstract
The white dot syndromes include a group of diseases which are characterized by multiple yellowish-white foci in the outer retina, retinal pigment epithelium, and choroid. For clinicians and researchers alike they present significant diagnostic and therapeutic challenges. White dot syndromes include primary inflammatory choriocapillaropathies, such as acute posterior multifocal placoid pigment epitheliopathy (APMPPE)/acute multifocal ischemic choriocapillaropathy (AMIC), multiple evanescent white dot syndrome (MEWDS)/acute idiopathic blind spot enlargement (AIBSE), multifocal choroiditis (MFC), punctate inner choroidopathy (PIC), serpiginous choroiditis (SC), acute zonal occult outer retinopathy (AZOOR), and acute macular neuroretinopathy (AMN). Among the primary stromal choroiditis is birdshot retinochoroidopathy (BSRC); however, the pathogenesis of these disorders is largely unknown. Immunological reactions to previous viral infections with a genetic disposition seem to be a common denominator.

Abstract
Myopia is a major cause of visual impairment. Its prevalence is growing steadily, especially in East Asia. Despite the immense disease and economic burden, there are currently no Food and Drug Administration-approved drugs for myopia. This review aims to summarise pharmaceutical interventions of myopia at clinical and preclinical stages in the last decade and discuss challenges for preclinical myopia drugs to progress to clinical trials. Atropine and oral 7-methylxanthine are shown to reduce myopia progression in human studies. The former has been extensively studied and is arguably the most successful medication. However, it has side effects and trials on low-dose atropine are ongoing. Other pharmaceutical agents being investigated at a clinical trial level include ketorolac tromethamine, oral riboflavin and BHVI2 (an experimental drug). Since the pathophysiology of myopia is not fully elucidated, numerous drugs have been tested at the preclinical stage and can be broadly categorised based on the proposed mechanisms of myopisation, namely antimuscarinic, dopaminergic, anti-inflammatory and more. However, several agents were injected intravitreally or subconjunctivally, hindering their progress to human trials. Furthermore, with atropine being the most successful medication available, future preclinical interventions should be studied in combination with atropine to optimise the treatment of myopia.

We report the outcomes after an essentially long follow-up period of up to 14 years and provide evidence of the effectiveness of intravitreal injections of bevacizumab and dexamethasone 0.7 mg in punctate inner choroidopathy patients with choroidal neovascular membrane formation. Case series presentation This is a retrospective case series of three female patients with punctate inner choroidopathy who were treated with intravitreal injections anti-vascular endothelial growth factor agent (bevacizumab, 1.25 mg/0.05 mL). Two patients also received intravitreal dexamethasone 0.7 mg. Once a choroidal neovascular membrane developed, the outcome was poor with a best-corrected visual acuity of 6/60 or counting fingers in the affected eyes. The patients were followed up for 5, 14 and 8 years. Conclusion The use of dexamethasone 0.7 mg in punctate inner choroidopathy yielded encouraging results and long periods of stability. When choroidal neovascular membrane complicates the primary disease, the prognosis is unfavourable, especially if the macula integrity has already been considerably affected. On the contrary, aggressive early therapy and continued monthly monitoring can prevent severe fibrosis, as showed in previous reports. Further larger-scale studies are needed to evaluate the efficacy of intravitreal dexamethasone 0.7 mg and bevacizumab as an alternative treatment in non-infectious uveitis.
