The first-in-class pyrazole-based dual InhA-VEGFR inhibitors towards integrated antitubercular host-directed therapy. Bioorg Chem 2024; 145:107179.

Abstract
Several facets of the host response to tuberculosis have been tapped for clinical investigation, especially targeting angiogenesis mediated by VEGF signaling from infected macrophages. Herein, we rationalized combining the antiangiogenic effects of VEGFR-2 blockade with direct antitubercular InhA inhibition in single hybrid dual inhibitors as advantageous alternatives to the multidrug regimens. Inspired by expanded triclosans, the ether ligation of triclosan was replaced by rationalized linkers to assemble the VEGFR-2 inhibitors thematic scaffold. Accordingly, new series of 3-(p-chlorophenyl)-1-phenylpyrazole derivatives tethered to substituted ureas and their isosteres were synthesized, evaluated against Mycobacterium tuberculosis virulent cell line H37Rv, and assessed for their InhA inhibitory activities. The urea derivatives 8d and 8g exhibited the most promising antitubercular activity (MIC = 6.25 µg/mL) surpassing triclosan (MIC = 20 µg/mL) with potential InhA inhibition, thus identified as the study hits. Interestingly, both compounds inhibited VEGFR-2 at nanomolar IC50 (15.27 and 24.12 nM, respectively). Docking and molecular dynamics simulations presumed that 8d and 8g could bind to their molecular targets InhA and VEGFR-2 posing essential stable interactions shared by the reference inhibitors triclosan and sorafenib. Finally, practical LogP, Lipinski's parameters and in silico ADMET calculations highlighted their drug-likeness as novel leads in the arsenal against TB.

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
PURPOSE To compare visual outcome and recurrence rates of eyes with noninfectious inflammatory choroidal neovascularization (CNV) treated with or without anti-vascular endothelial growth factor (VEGF) injections and immunosuppression. DESIGN Retrospective, nonrandomized clinical study. METHODS Participants: Patients with CNV secondary to noninfectious inflammatory causes who attended uveitis clinics at Moorfields Eye Hospital between January 2000 and April 2016. Data were gathered from the clinical notes of all subjects examined in clinic. MAIN OUTCOME MEASURES change in best-corrected visual acuity (BCVA), mean time to CNV recurrence, moderate vision loss (≤20/50), and severe vision loss (≤20/200). RESULTS A total of 166 patients (204 eyes) with noninfectious inflammatory CNV were included in this study with a median follow-up of 6.9 years (interquartile range: 2.9-11.7; 1652 eye-years). The mean BCVA at the time of CNV diagnosis was 0.38 ± 0.05 logarithm of the minimum angle of resolution (logMAR) (Snellen equivalent 20/47) in the eyes that received the first-line anti-VEGF treatment and 0.44 ± 0.03 logMAR (Snellen equivalent 20/55) in the eyes on other treatment modalities (P = .39). Eyes treated first with anti-VEGF (n = 55) received the mean of 4.35 ± 0.53 injections and showed a statistically significant improvement in vision at all time points (P < .001) except for a 5-year visit (P = .25). The rest of the eyes demonstrated no significant change in vision throughout follow-up (all P > .05). At the final visit, the mean BCVA was 0.26 ± 0.11 logMAR (Snellen equivalent 20/36) in the former and 0.35 ± 0.06 logMAR (Snellen equivalent 20/44) in the latter. The mean time to CNV recurrence was 186 ± 15.1 months, and the risk was significantly reduced by treatment with oral corticosteroids (adjusted hazard ratio = 0.32, confidence interval: 0.17-0.59, P < .001) or anti-VEGF injections (adjusted hazard ratio = 0.31, confidence interval: 0.18-0.52, P < .001). CONCLUSIONS Eyes that developed inflammatory CNV were at risk of vision loss. Those receiving early anti-VEGF injections achieved a better visual outcome and had a reduced risk of CNV recurrence. Oral corticosteroids also had an effect that reduces the risk of recurrence in eyes previously treated.

Abstract
A case of peripapillary choroidal neovascular membrane (PCNM) secondary to sarcoidosis-related panuveitis successfully treated with anti-vascular endothelial growth factor (anti-VEGF) agents and systemic immunomodulatory therapy is reported. Diagnosis and follow-up were based on fundoscopic, optical coherence tomography as well as fluorescein angiography findings. A 45-year-old female patient presented with sudden onset bilateral blurring of vision. Fundoscopy revealed bilateral granulomatous panuveitis with solitary peripheral granuloma in the right eye and PCNM in the left eye. Diagnostic work-up including conjunctival biopsy confirmed the diagnosis of sarcoidosis. Topical and systemic corticosteroids controlled the inflammation. Within 4 weeks, PCNM showed rapid enlargement (best-corrected visual acuity [BCVA]: 6/60) with foveal involvement. Monthly intravitreal aflibercept injections and systemic methotrexate were administered. After 5 aflibercept injections, anatomical and functional improvement was noted (BCVA: 6/6). Due to aflibercept unavailability, further treatment included ranibizumab injections. During a 50-month follow-up period, every anti-VEGF injection was followed by total NV regression and 6/6 BCVA. Both aflibercept and ranibizumab appear to be effective in the treatment of PCNM secondary to sarcoidosis.

Abstract
Herpes simplex virus type 1 (HSV-1)-infected corneas can develop a blinding immunoinflammatory condition called herpes stromal keratitis (HSK), which involves the loss of corneal sensitivity due to retraction of sensory nerves and subsequent hyperinnervation with sympathetic nerves. Increased concentrations of the cytokine VEGF-A in the cornea are associated with HSK severity. Here, we examined the impact of VEGF-A on neurologic changes that underly HSK using a mouse model of HSV-1 corneal infection. Both CD4+ T cells and myeloid cells produced pathogenic levels of VEGF-A within HSV-1-infected corneas, and CD4+ cell depletion promoted reinnervation of HSK corneas with sensory nerves. In vitro, VEGF-A from infected corneas repressed sensory nerve growth and promoted sympathetic nerve growth. Neutralizing VEGF-A in vivo using bevacizumab inhibited sympathetic innervation, promoted sensory nerve regeneration, and alleviated disease. Thus, VEGF-A can shape the sensory and sympathetic nerve landscape within the cornea, with implications for the treatment of blinding corneal disease.

Results of Intravitreal Anti-Vascular Endothelial Growth Factor Therapy in Inflammatory Choroidal Neovascularization. J Curr Ophthalmol 2021; 33:68-74. [PMID: 34084960 PMCID: PMC8102949 DOI: 10.4103/joco.joco_128_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Revised: 07/08/2020] [Accepted: 08/01/2020] [Indexed: 11/25/2022] Open
Abstract
Purpose: To report the visual outcomes of intravitreal (IVT) anti-vascular endothelial growth factor (anti-VEGF) in inflammatory choroidal neovascularization (iCNV). Methods: A retrospective study of 43 eyes of 38 patients with active choroidal neovascularization (CNV) related to ocular inflammatory disease, treated with IVT injections of anti-VEGF (bevacizumab, ranibizumab, or aflibercept), with or without associated systemic anti-inflammatory therapy, at Fattouma Bourguiba University Hospital, Monastir, Tunisia (24 eyes of 23 patients) and at Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico, Milan, Italy (19 eyes of 15 patients) from January 1, 2013, to December 31, 2018. Results: The mean age was 35.5 ± 16.4 years. The sex ratio male:female was 0.27. Seventeen eyes (39.5%) of 17 patients (44.7%) had only anti-VEGF injections, and 26 eyes (60.5%) of 21 patients (45.3%) had anti-VEGF injections and associated systemic anti-inflammatory therapy. Bevacizumab was injected in 36 eyes (83.7%), ranibizumab in six eyes (14%), and aflibercept in one eye (2.3%). Mean follow-up was 20.3 ± 19.2 months (range, 6–106 months). Mean visual acuity improved from 0.8 ± 0.37 logMAR (approximate Snellen equivalent 20/125) to 0.51 ± 0.42 logMAR (approximate Snellen equivalent 20/63) (P < 0.001). Mean central macular thickness on optical coherence tomography decreased from 403.7 ± 121.9 to 293.7 ± 82.8 μm (P < 0.001). Mean gain of vision was 2.9 ± 3.1 lines. The mean number of injections was 2.5. Twenty eyes (46.5%) received a single injection. There were no side effects related to the IVT injections of anti-VEGF. Conclusions: CNV is a sight-threatening complication of uveitis. IVT anti-VEGF seems to be an effective and safe treatment for iCNV when inflammation is controlled.

Abstract
BACKGROUND AND OBJECTIVE Neovascularization is a sight-threatening, uncommon complication of posterior uveitis that often goes undetected until persistent clinical findings appear, or in light of treatment failure. This could be attributed to the relative similarity of activity signs in inflammatory neovascular membranes (NVM) and active posterior uveitis. The purpose of the present study is to recognize imaging features that distinguish uveitic neovascularization from active uveitis using swept-source optical coherence tomography angiography (SS-OCTA). PATIENTS AND METHODS Cross-sectional study. Patients with posterior uveitis with visual acuity (VA) decrease and at least one of the following findings were assessed by SS-OCTA: retinal thickening, subretinal or intraretinal fluid, and retinal hyperreflective areas. The change of VA and imaging features after treatment with anti-vascular endothelial growth factor (VEGF) therapy were analyzed in cases with inflammatory NVM. RESULTS Forty-five eyes of 40 patients were evaluated. Twenty-four eyes (53.3%) showed signs of activity, of which eight (33.3%) presented inflammatory NVM. Imaging features that differentiate inflammatory neovascularization from active posterior uveitis included: vitreous cellularity (P = .003), outer retinal infiltration (P = .08), choroidal thickness (P = .003), posterior shadowing (P = .013), subretinal fluid (P = .04), and neovascular network (P ≤ .001). According to NVM characteristics by OCTA, multiple anastomoses and peripheral arcades were visualized at baseline in 85.7% of cases. Mean pre-operative best-corrected VA of inflammatory NVM was 20/150 (logMAR: 0.88 ± 0.60) with significant improvement to 20/40 (logMAR: 0.32 ± 0.22) after anti-VEGF treatment (P = .027). CONCLUSIONS SS-OCTA achieves the distinction of inflammatory NVM from active posterior uveitis through specific imaging features. Inflammatory neovascularization presents a suitable response after anti-VEGF therapy. [Ophthalmic Surg Lasers Imaging Retina. 2021;52:129-137.].

Abstract
ABSTRACT
Mycobacteria have co-evolved with their hosts resulting in pathogens adept at intracellular survival. Pathogenic mycobacteria actively manipulate infected macrophages to drive granuloma formation while subverting host cell processes to create a permissive niche. Granuloma residency confers phenotypic antimicrobial resistance by physically excluding or neutralising antibiotics. Host-directed therapies (HDTs) combat infection by restoring protective immunity and reducing immunopathology independent of pathogen antimicrobial resistance status. This review covers innovative research that has discovered ‘secondary’ symptoms of infection in the granuloma stroma are actually primary drivers of infection and that relieving these stromal pathologies with HDTs benefits the host. Advances in our understanding of the relationship between tuberculosis and the host vasculature, haemostatic system and extracellular matrix reorganisation are discussed. Preclinical and clinical use of HDTs against these stromal targets are summarised.

Abstract
BACKGROUND Pseudophakic cystoid macular edema (PCME) remains one of the most common visionthreatening complication of phacoemulsification cataract surgery (PCS). Pharmacological therapy is the current mainstay of both prophylaxis, and treatment of PCME in patients undergoing PCS. We aimed to review pharmacological treatment options for PCME, which primarily include topical steroids, topical nonsteroidal antiinflammatory drugs (NSAIDS), periocular and intravitreal steroids, as well as anti-vascular endothelial growth factor therapy. METHODS The PubMed and Web Of Science web platforms were used to find relevant studies using the following keywords: cataract surgery, phacoemulsification, cystoid macular edema, and pseudophakic cystoid macular edema. Of articles retrieved by this method, all publications in English and abstracts of non-English publications were reviewed. Other studies were also considered as a potential source of information when referenced in relevant articles. The search revealed 193 publications. Finally 82 articles dated from 1974 to 2018 were assessed as significant and analyzed. RESULTS Based on the current literature, we found that corticosteroids remain the mainstay of PCME prophylaxis in uncomplicated cataract surgery, while it is still unclear if NSAID can offer additional benefits. In patients at risk for PCME development, periocular subconjunctival injection of triamcinolone acetonide may prevent PCME development. For PCME treatment the authors recommend a stepwise therapy: initial topical steroids and adjuvant NSAIDs, followed by additional posterior sub-Tenon or retrobulbar corticosteroids in moderate PCME, and intravitreal corticosteroids in recalcitrant PCME. Intravitreal anti-vascular endothelial growth factor agents may be considered in patients unresponsive to steroid therapy at risk of elevated intraocular pressure, and with comorbid macular disease. CONCLUSION Therapy with topical corticosteroids and NSAIDs is the mainstay of PCME prophylaxis and treatment, however, periocular and intravitreal steroids should be considered in refractory cases.

Abstract
The spectre of the coming post-antibiotic age demands novel therapies for infectious diseases. Tuberculosis (TB), caused by Mycobacterium tuberculosis, is the single deadliest infection throughout human history. M. tuberculosis has acquired antibiotic resistance at an alarming rate with some strains reported as being totally drug resistant. Host-directed therapies (HDTs) attempt to overcome the evolution of antibiotic resistance by targeting relatively immutable host processes. Here, I hypothesise the induction of hypoxia via anti-angiogenic therapy will be an efficacious HDT against TB. I argue that anti-angiogenic therapy is a modernisation of industrial revolution era sanatoria treatment for TB, and present a view of the TB granuloma as a 'bacterial tumour' that can be treated with anti-angiogenic therapies to reduce bacterial burden and spare host immunopathology. I suggest two complementary modes of action, induction of bacterial dormancy and activation of host hypoxia-induced factor (HIF)-mediated immunity, and define the experimental tools necessary to test this hypothesis.

Abstract
Inflammatory choroidal neovascular membranes are challenging to diagnose and manage. A number of uveitic entities may be complicated by the development of choroidal neovascularization leading to a decrease in central visual acuity. In conditions such as punctate inner choroidopathy, development of choroidal neovascularization is extremely common and must be suspected in all cases. On the other hand, in patients with conditions such as serpiginous choroiditis, and multifocal choroiditis, it may be difficult to differentiate between inflammatory choroiditis lesions and choroidal neovascularization. Multimodal imaging analysis, including the recently introduced technology of optical coherence tomography angiography, greatly aid in the diagnosis and management of inflammatory choroidal neovascularization. Management of these neovascular membranes consists of anti-vascular growth factor agents, with or without concomitant anti-inflammatory and/or corticosteroid therapy.

Abstract
Choroidal neovascular membrane (CNV) is a very rare complication in patients with sympathetic ophthalmia. We hereby report a 38-year-old man who developed a type 2 CNV in his only seeing (left) eye while under systemic steroid treatment. Systemic therapy was revised and a total of 5 intravitreal aflibercept injections (2 mg each) were administered over a period of 8 months. Good anatomic and functional outcome was noted at the last visit. Anti-vascular endothelial growth factor injection may be an important adjunct to systemic therapy in eyes with with sympathetic ophthalmia-associated CNV.

Abstract
OBJECTIVE To evaluate the effect of anti-vascular endothelial growth factor (VEGF) on juxtafoveal choroidal neovascularization (CNV) secondary to multifocal choroiditis (MFC) and wet age-related macular degeneration (AMD). METHODS In this retrospective, comparative study, 20 unique eyes with CNV were divided into two groups: 10 patients affected by MFC and 10 patients diagnosed with wet AMD. They all received local intravitreal (IVT) injections of ranibizumab, with 6 months of follow-up. Retreatment injections were performed based on findings suggestive of active neovascularization. RESULTS Significant improvements were observed in the juxtafoveal CNV lesions, and average central macular thickness decreased in both groups following the anti-VEGF therapy (P<0.05). The average number of injections used in MFC patients was 1.6, while three injections on average were used in wet AMD patients (Z=-2.844, P=0.009). Best-corrected visual acuity was significantly improved in MFC patients after anti-VEGF therapy (P<0.05), and there was no significant difference in wet AMD patients between before anti-VEGF therapy and 6 months later (P>0.05). CONCLUSIONS IVT ranibizumab resulted in good clinical outcomes for juxtafoveal CNV secondary to MFC and wet AMD, but the average number of injections used in MFC was fewer than that used in wet AMD over a 6-month observation period. Compared with the wet AMD group, visual acuity was obviously improved in the MFC group at 6 months.

Abstract
Purpose: To analyze the ability of optical coherence tomography angiography to identify choroidal neovascularization in multifocal choroiditis and to describe active and inactive choroidal neovascularization findings. Methods: Retrospective study of consecutive patients with multifocal choroiditis and choroidal neovascularization examined between January and November 2016. In addition to usual exams, optical coherence tomography angiography (AngioPlex™ CIRRUS™ HD-OCT model 5000; Carl Zeiss Meditec, Inc., Dublin, CA, USA) images were assessed for morphological analysis: choroidal neovascularization size, choroidal neovascularization margin (well or poorly circumscribed), choroidal neovascularization shape (tangled or interlacing), choroidal neovascularization core (feeder vessel) and dark ring around the choroidal neovascularization. Results: A total of 10 eyes were included. Optical coherence tomography angiography identified all choroidal neovascularization. Active choroidal neovascularization had well-circumscribed margins (67%), interlacing shape (83%), and a surrounding dark ring (83%). Inactive choroidal neovascularization had rather poorly circumscribed margins (75%), tangled shape, and “dead tree” appearance (50%) with less frequently a surrounding dark ring (50%). Conclusion: Optical coherence tomography angiography is adapted to confirm the diagnosis of choroidal neovascularization complicating multifocal choroiditis, but it is still insufficient to differentiate active and inactive lesions.

Abstract
Purpose While there are many known etiologies of choroidal neovascularization (CNV), tuberculosis is not a well-known causative agent. In this case series, we highlight CNV occurring secondary to tuberculous chorioretinitis, its presentation, and its management. Observations We retrospectively reviewed the charts and imaging of four patients who presented with presumed tuberculous chorioretinitis and CNV. Three of these patients had signs of intraocular inflammation and were also found to have active macular CNV. The one remaining patient had chorioretinal scars from prior posterior uveitis and previously treated macular CNV membranes. The three patients with active disease were started on anti-tuberculosis medications and oral corticosteroids, and they also received intravitreal anti-vascular endothelial growth factor (VEGF) injections as needed for the CNV. There was a significant improvement in the clinical course of all three patients with active disease—the intraocular inflammation subsided, and CNV recurrences were mitigated. Upon completion of systemic treatment, all patients have remained quiescent. Conclusions and importance Our findings demonstrate that CNV may occur in the course of tuberculous chorioretinitis with marked loss of vision, and management with anti-tuberculosis medications, oral corticosteroids, and intravitreal anti-VEGF injections results in notable improvement in their clinical course.

Abstract
Uveitis is an important cause of vision loss worldwide due to its sight-threatening complications, especially cystoid macular edema, as well as choroidal neovascularization, macular ischemia, cataract, and glaucoma. Systemic corticosteroids are the mainstay of therapy for noninfectious posterior uveitis; however, various systemic side effects can occur. Intravitreal medication achieves a therapeutic level in the vitreous while minimizing systemic complications and is thus used as an exciting alternative. Corticosteroids, antivascular endothelial growth factors, immunomodulators such as methotrexate and sirolimus, and nonsteroidal anti-inflammatory drugs are currently available for intravitreal therapy. This article reviews the existing literature for efficacy and safety of these various options for intravitreal drug therapy for the management of noninfectious uveitis (mainly intermediate, posterior, and panuveitis).

Abstract
AIM To assess the efficacy of intravitreal ranibizumab for the treatment of new onset inflammatory choroidal neovascularisation (iCNV), including both uveitic and idiopathic CNVs. METHODS Single-centre, open-label, non-randomised Phase IIb clinical trial. Patients fulfilling strict entry criteria of new onset iCNV were given monthly intravitreal ranibizumab injections for 3 months. Thereafter, re-treatment was based on evidence of persisting activity. All patients completed trial follow-up. Optical coherence tomography (OCT) and best-corrected visual acuity (BCVA) were performed at every visit. Fluorescein angiography was performed at baseline, months 4 and 12. Descriptive analysis and Wilcoxon non-parametric test were performed for analysis. RESULTS 15 patients, 10 women with a mean age of 48.8 years (range 24-85 years) were included in the study. The mean number of injections was 4.33 (range 3-7). There was a statistically significant difference in the BCVA at month 4 (p=0.001) and at month 12 (p=0.001) compared with baseline. The mean gain in BCVA at month 4 compared with baseline was 20±15.36 letters (mean±SD), and at month 12 was 21±16.97 letters. There was a statistically significant difference in the mean central subfield thickness (CST) at baseline versus month 4 (p=0.003) and month 12 (p=0.001). CONCLUSION Patients gained vision (mean of 21 letters at 12 months) and showed reduced CST. These results support the continued use of ranibizumab in the treatment of iCNV.

Abstract
Ocular angiogenesis and macular oedema are major causes of sight loss across the world. Aberrant neovascularisation, which may arise secondary to numerous disease processes, can result in reduced vision as a result of oedema, haemorrhage, and scarring. The development of antivascular endothelial growth factor (anti-VEGF) agents has revolutionised the treatment of retinal vasogenic conditions. These drugs are now commonly employed for the treatment of a plethora of ocular pathologies including choroidal neovascularisation, diabetic macular oedema, and retinal vein occlusion to name a few. In this paper, we will explore the current use of anti-VEGF in a variety of retinal diseases and the impact that these medications have had on visual outcome for patients.

Abstract
OBJECTIVES To assess the safety of intravitreal bevacizumab (IVB) as a monotherapy and to evaluate the relationship between quality of treatment and adverse events. DATA SOURCES Cochrane Library, Ovid MEDLINE, MEDLINE in-process, Ovid EMBASE and Toxicology Literature Online (TOXLINE) from January 2009 to May 2012. Studies included in an earlier systematic review were also assessed for inclusion. STUDY ELIGIBILITY CRITERIA, PARTICIPANTS AND INTERVENTIONS Randomised controlled trials (RCTs), controlled trials or observational studies including ≥10 participants reporting adverse events data following IVB monotherapy as a primary treatment in patients (aged 18 years or more) with any eye condition were included. STUDY APPRAISAL AND SYNTHESIS METHODS Study selection was undertaken independently by a minimum of two reviewers using pre-defined criteria. Data abstraction and quality assessment were performed by one reviewer, and then checked by a second reviewer. Study quality was assessed for only RCTs in accordance to the Cochrane Risk of Bias Tool. Additional items relating to safety data were also assessed. Results were tabulated or meta-analysed as appropriate. RESULTS 22 RCTs and 67 observational studies were included. Only two RCTs reported valid safety data. Rates of serious adverse events following treatment were low. There was insufficient data to explore the relationship between the incidence of adverse events and quality of IVB injection. LIMITATIONS A majority of relevant existing studies were characterised by small sample sizes, unclear diagnostic criteria and reporting of safety outcomes. CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS Available evidence demonstrates low rates of serious local and systemic adverse events following treatment. However, the role of IVB quality in the incidence of adverse events remains unclear. Robust evidence is needed to examine the relationship between the incidence of adverse events and variables such as injection techniques, pre-existing risk factors (eg, immunosuppression, cross-contamination) and quality of IVB treatment.

Abstract
Inflammatory choroidal neovascularization is a severe but uncommon complication of uveitis, more frequent in posterior uveitis such as punctate inner choroidopathy, multifocal choroiditis, serpiginous choroiditis, and Vogt-Koyanagi-Harada syndrome. Its pathogenesis is supposed to be similar to the wet age related macular degeneration: hypoxia, release of vascular endothelial growth factor, stromal cell derived factor 1-alpha, and other mediators seem to be involved in the uveitis-related choroidal neovascularization. A review on the factors implicated so far in the pathogenesis of inflammatory choroidal neovascularization was performed. Also we reported the success rate of single studies concerning the therapies of choroidal neovascularization secondary to uveitis during the last decade: photodynamic therapy, intravitreal bevacizumab, and intravitreal ranibizumab, besides steroidal and immunosuppressive therapy. Hereby a standardization of the therapeutic approach is proposed.

[PMID: 23795984 DOI: 10.1016/j.ajo.2013.04.040] [Citation(s) in RCA: 75] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2013] [Revised: 04/29/2013] [Accepted: 04/30/2013] [Indexed: 11/23/2022]
Abstract
PURPOSE To evaluate the risk, risk factors, and visual impact of choroidal neovascularization (CNV) in uveitis cases. DESIGN Retrospective cohort study. METHODS Standardized medical record review at 5 tertiary centers. RESULTS Among 15,137 uveitic eyes (8868 patients), CNV was rare in the cases of anterior or intermediate uveitis. Among the 4041 eyes (2307 patients) with posterior uveitis or panuveitis, 81 (2.0%) had CNV at presentation. Risk factors included posterior uveitis in general and specific uveitis syndromes affecting the outer retina-retinal pigment epithelium-choroid interface. Among the 2364 eyes (1357 patients) with posterior uveitis or panuveitis and free of CNV at the time of cohort entry, the cumulative 2-year incidence of CNV was 2.7% (95% confidence interval [CI], 1.8% to 3.5%). Risk factors for incident CNV included currently active inflammation (adjusted hazard ratio [aHR], 2.13; 95% CI, 1.26 to 3.60), preretinal neovascularization (aHR, 3.19; 95% CI, 1.30 to 7.80), and prior diagnosis of CNV in the contralateral eye (aHR, 5.79; 95% CI, 2.77 to 12.09). Among specific syndromes, the incidence was greater in Vogt-Koyanagi-Harada syndrome (aHR, 3.37; 95% CI, 1.52 to 7.46) and punctate inner choroiditis (aHR, 8.67; 95% CI, 2.83 to 26.54). Incident CNV was associated with a 2-line loss of visual acuity (+0.19 logarithm of the minimal angle of resolution units; 95% CI, 0.079 to 0.29) from the preceding visit. CONCLUSIONS CNV is an uncommon complication of uveitis associated with visual impairment that occurs more commonly in forms affecting the outer retina-retinal pigment epithelium-choroid interface, during periods of inflammatory activity, in association with preretinal neovascularization, and in second eyes of patients with unilateral CNV. Because CNV is treatable, a systematic approach to early detection in high-risk patients may be appropriate.

Abstract
Serpiginous choroiditis (SC) is a posterior uveitis displaying a geographic pattern of choroiditis, extending from the juxtapapillary choroid and intermittently spreading centrifugally. The choroiditis involves the overlying retinal pigment epithelium, and the outer retina. This intraocular inflammation typically involves both eyes in otherwise healthy, middle-aged individuals with no familial or ethnic predilection. Pathogenesis is unclear; based on limited histopathologic studies, however, favorable response to immunosuppressive agents, and the absence of association with systemic or local infectious or noninfectious diseases, an organ-specific autoimmune inflammation seems likely to be the underlying process. Patients, particularly from tuberculosis-endemic regions, may present with fundus changes simulating SC, but show evidence of active tuberculosis and/or the presence of mycobacterial DNA in the aqueous humor. This has been referred to as serpiginous-like choroiditis, but we prefer the description multifocal serpiginoid choroiditis (MSC). We present the distinguishing features of SC and infectious multifocal serpiginoid choroiditis simulating SC. The distinction is crucial to avoid unnecessarily treating SC with antimicrobial agents. Advances in diagnostic and imaging modalities can help differentiate SC from MSC. Novel local and systemic treatment approaches improve the outcome and preserve vision in SC.

Abstract
The first antivascular endothelial growth factor (anti-VEGF) was developed as an anticancer drug for colonic carcinomas. Since then, anti-VEGFs have developed in scope and indications. They have revolutionized the treatment of exudative macular degeneration and have had a major impact on treatment of several other conditions. This has resulted in an increased number of patients seeking treatment with new treatment options and has had a considerable financial impact on health care resources. Anti-VEGFs have been used in the treatment of all age groups of the population ranging from infants where it is used for treatment of retinopathy of prematurity to the elderly where it is used in exudative macular eegeneration.

Abstract
Reverse thermal gels have numerous biomedical implications, as they undergo physical gelation upon temperature increases and can incorporate biomolecules to promote tissue repair. Such a material is developed for the sustained release of bevacizumab (Avastin), a drug used to treat age-related macular degeneration. The polymer, poly(ethylene glycol)-poly(serinol hexamethylene urethane) (ESHU), forms a physical gel when heated to 37 °C and shows good cytocompatibility with ocular cells. ESHU is capable of sustaining bevacizumab release over 17 weeks in vitro, and the release kinetics can be altered by changing the drug dose and the ESHU concentration. These results suggest that ESHU is biologically safe, and suitable for ocular drug delivery.

Abstract
The eye is probably the most attractive site of the body for treatment using locally delivered therapeutic agents. An ideal indication for such an approach is noninfectious posterior uveitis. Since intraocular structures of the posterior segment are difficult to reach and are otherwise accessible only by systemic treatment, current interest is focused on the pros and cons of intravitreal drug delivery. Because of its chronic and recurrent nature, the long-term release of anti-inflammatory agents is a major treatment goal. Intravitreal injections, intravitreal implants and biodegradable devices are the most commonly used and approved approaches to deliver various agents to the vitreous. Because of their broad and potent effects, corticosteroids (CS) have been the first-line candidates for intraocular delivery. An increasing spectrum of CS preparations including nondegradable and biodegradable devices is currently available. Since repeated and long-term applications bear the risk of steroid-related complications such as increased intraocular pressure and cataract, alternative agents are currently being tested. Intravitreal injection of methotrexate, anti-VEGF (vascular endothelial growth factor), anti-TNFα (tumor necrosis factor α) and sirolimus have also been applied in patients with conflicting results. Intravitreal treatment has significantly reduced the incidence of adverse effects compared to systemic application, but due to greater ocular side effects there are still some limitations.

Abstract
OBJECTIVE To assess the 3-year visual outcome of intravitreal bevacizumab in inflammatory ocular neovascularization. DESIGN Experimental study. METHODS Retrospective multicenter consecutive case series in 81 patients with inflammatory ocular neovascularization refractory to standard therapy and treated with intravitreal bevacizumab. The outcome measures included improvement of best corrected visual acuity expressed as logarithm of minimum angle of resolution (logMAR) and paired comparison decrease in central foveal thickness by optical coherence tomography. RESULTS Mean best corrected visual acuity improved from baseline 0.699 (6/30 or 20/101) (SD 0.434) to 0.426 (6/16 or 20/53) (SD 0.428) (n = 81; p < 0.001), a gain of 2.7 lines (median 3 injections; 81 eyes; 81 patients). Paired comparisons revealed significant central foveal flattening at 3 years of 97.9 μm (n = 51; p < 0.001). In a subgroup analysis, visual improvement was significant for ocular histoplasmosis (p = 0.026); multifocal choroiditis (p = 0.05); serpiginous choroiditis (p = 0.028); ocular toxoplasmosis (p = 0.042); and punctate inner choroidopathy (p = 0.015). In a subgroup analysis, foveal flattening was significant for ocular histoplasmosis (p = 0.004); multifocal choroiditis (p = 0.007); serpiginous choroiditis (p = 0.011); and punctate inner choroidopathy (p = 0.001). Of the group, 5 eyes developed submacular fibrosis, 1 eye retinal pigment epithelial tear, and 1 eye macular ischemia in the context of vasculitis. CONCLUSION At 3 years, intravitreal bevacizumab sustained significant visual improvement of 2.7 lines and significant foveal flattening of 98 μm in a wide variety of inflammatory ocular diseases without major complications after a median of 3 injections.

Abstract
purpose. To test the efficacy of intravitreal bevacizumab (IB) in the treatment of inflammatory choroidal neovascularization (CNV).
Methods. A prospective interventional study on patients with subfoveal CNV secondary to posterior/diffuse uveitis treated with 1.5 mg/0.05 mL of IB. Eight eyes of 8 patients, with mean follow-up of 19.25±6 months, were included. The measurements adopted were 1) changes in best-corrected visual acuity (BCVA), 2) reduction in CNV size, and 3) changes in central foveolar thickness (CFT) measured by optical coherence tomography.
Results. The mean number of intravitreal injections was 3.75±1.38. After IB treatment, the mean BCVA improved significantly, from 0.27±0.10 before treatment to 0.5±0.29 after treatment (p<0.05). The CFT also responded well to IB, with 402.75±114.11 µm preoperatively, and after treatment 300.5±90.98 µm (p<0.01). Notably, all patients showed a reduction in the size of the CNV and BCVA remained stable or improved in 7 eyes (87.5%). No episode of active intraocular inflammation was observed and patients continued to receive their systemic steroid or immunosuppressive therapy.
Conclusions. Intravitreal bevacizumab may be an additional strategy in inflammatory CNV of eyes with controlled uveitis.

Abstract
PURPOSE To determine the incidence and to discuss pathogenic mechanisms of sympathetic ophthalmia in patients treated for choroïdal melanoma. DESIGN Retrospective. METHODS We analyzed the clinical and pathological data of 4867 patients, treated for choroïdal melanoma at Institute Curie-Orsay, between 1998 and 2011. Were involved patients with uveitis of the adelphe eye filling clinical and angiographic criteria of sympathetic ophthalmia. Extensive work-up was undertaken to rule out another etiology of the inflammation. RESULTS Three patients developed sympathetic ophthalmia respectively 7, 4 and 3 years after protontherapy.The incidence of this complication was 6.1 per 10000 patients treated by proton beam radiation. Ocular perforating injury was ruled out and radioactive effect of treatment was incriminated in the occurrence of sympathetic ophthalmia. CONCLUSION Sympathetic ophthalmia remains a rare complication which must be treated promptly and aggressively to prevent blindness.Proton beam irradiation could induce disruption of uveal tissue which enhances auto immune reactions.
