Abstract
Implantable drug delivery systems (IDDS) are an attractive alternative to conventional drug administration routes. Oral and injectable drug administration are the most common routes for drug delivery providing peaks of drug concentrations in blood after administration followed by concentration decay after a few hours. Therefore, constant drug administration is required to keep drug levels within the therapeutic window of the drug. Moreover, oral drug delivery presents alternative challenges due to drug degradation within the gastrointestinal tract or first pass metabolism. IDDS can be used to provide sustained drug delivery for prolonged periods of time. The use of this type of systems is especially interesting for the treatment of chronic conditions where patient adherence to conventional treatments can be challenging. These systems are normally used for systemic drug delivery. However, IDDS can be used for localised administration to maximise the amount of drug delivered within the active site while reducing systemic exposure. This review will cover current applications of IDDS focusing on the materials used to prepare this type of systems and the main therapeutic areas of application.

Abstract
Non-infectious uveitis (NIU) is a disorder with various etiologies and is characterized by eye inflammation, mainly affecting people of working age. An accurate diagnosis of NIU is crucial for appropriate therapy. The aim of therapy is to improve vision, relieve ocular inflammation, prevent relapse, and avoid treatment side effects. At present, corticosteroids are the mainstay of topical or systemic therapy. However, repeated injections are required for the treatment of chronic NIU. Recently, new drug delivery systems that may ensure intraocular delivery of therapeutic drug levels have been highlighted. Furthermore, with the development of immunosuppressants and biologics, specific therapies can be selected based on the needs of each patient. Immunosuppressants used in the treatment of NIU include calcineurin inhibitors and antimetabolites. However, systemic immunosuppressive therapy itself is associated with adverse effects due to the inhibition of immune function. In patients with refractory NIU or those who cannot tolerate corticosteroids and immunosuppressors, biologics have emerged as alternative treatments. Thus, to improve the prognosis of patients with NIU, NIU should be managed with different drugs according to the response to treatment and possible side effects.

Abstract
PURPOSE This review aims to provide an update on the clinical presentation, etiologies, complications, and treatment options in intermediate uveitis (IU). METHODS Narrative literature review. RESULTS IU affects all age groups with no clear gender predominance and has varied etiologies including systemic illnesses and infectious diseases, or pars planitis. In some instances, IU may be the sole presentation of an underlying associated condition or disease. Management of IU and its complications include administration of corticosteroids, antimetabolites, T-cell inhibitors, and/or biologics, along with surgical interventions, with varying degrees of effectiveness across literature. In particular, increasing evidence of the safety and efficacy of immunomodulatory agents and biologics has seen greater adoption of these therapies in clinical practice. CONCLUSIONS IU is an anatomical description of uveitis, involving intraocular inflammation of the vitreous, peripheral retinal vasculature, and pars plana. Various treatment options for intermediate uveitis are currently used in practice.

Abstract
Background Regional corticosteroid therapy for noninfectious uveitis is well-established but usage patterns have not been studied extensively. This study aims to assess practice patterns of retina and uveitis specialists regarding their preferences on the use of local corticosteroid therapy. Methods A 13-question survey was developed regarding the practice patterns of regional corticosteroid use in specific situations and populations. The survey was distributed to both the American Uveitis Society and Macula Society. Results Responses from 87 ophthalmologists were analyzed. The two most commonly used drugs were the dexamethasone intravitreal implant (Ozurdex®) and posterior sub-tenon’s triamcinolone (also known as posterior sub-Tenon’s Kenalog, or PSTK). Regional corticosteroids were used more frequently as first-line treatment in more than half of posterior uveitis cases when compared to anterior uveitis (39.1–46.0% vs 10.3%, respectively). Respondents were more willing to use regional corticosteroids in more than half of unilateral uveitis cases than in bilateral cases (54.7% vs 18.6%, respectively). A majority of respondents (67.1%) stated that they would avoid using regional corticosteroids in patients under 8 years old. Conclusions Our results demonstrate more frequent regional corticosteroid use in posterior segment uveitis, unilateral cases, and avoidance in younger pediatric patients. Overall, the variability in these responses highlights the need for guidelines regarding regional corticosteroid use.

Abstract
OBJECTIVE Chronic uveitis is a common manifestation of pediatric rheumatologic conditions and may result in irreversible blindness and long-term disability. While chronic anterior uveitis is the most commonly encountered ocular manifestation of rheumatic disease, little is known about the clinical presentation, management, and long-term outcome of more complex eye conditions such as pars planitis (PP), panuveitis (PU), and Vogt-Koyanagi-Harada disease (VKH). The present study was undertaken to comprehensively assess the long-term safety and efficacy of disease-modifying antirheumatic drugs (DMARDs) and biologics for the treatment of pediatric and adolescent patients with PP, PU, and VKH. METHODS We retrospectively reviewed a cohort of 75 children and adolescents with idiopathic PP (n = 50), PU (n = 12), and VKH (n = 14) followed by the Pediatric Rheumatology Core at Children's Hospital Los Angeles and evaluated referral patterns, clinical presentation, treatment response, and long-term clinical outcome. RESULTS Patients were followed for an average of 52 months. Their mean age at disease onset was 10 years. Bilateral eye involvement was seen in 87% of the patients. At first presentation to an ophthalmologist, glaucoma was noted in 21% of patients and vision loss (<20/40) in 87% of patients, while legal blindness (≤20/200 in the better-seeing eye) was diagnosed in 18 of 75 (24%) of patients (PP 22%, PU 36%, and VKH 21%). The average referral time to a pediatric rheumatologist was 13 months (range 1-96 months). Topical steroids were used in all patients, but 98% of patients required additional DMARDs, and 73% required therapy with biologics. After a mean of 52 months, 35% of patients across all disease groups had significant vision loss or were blind, and only 28% were in clinical remission without medications. The worst outcome was observed in children with PU. Regression analysis, young age at onset, delayed referral to a pediatric rheumatologist, and chronic disease were strong predictors for the risk of long-term blindness. CONCLUSION PP, PU, and VKH involve a high risk of permanent vision loss and should be managed by a skilled rheumatologist as early and as aggressively as possible.

Abstract
The visual outcome of uveitic cataract surgery depends on the underlying uveitic diagnosis, the presence of vision-limiting pathology and perioperative optimization of disease control. A comprehensive preoperative ophthalmic assessment for the presence of concomitant ocular pathology, with particular emphasis on macula and optic nerve involvement, is essential to determine which patients will benefit from improved vision after cataract surgery. Meticulous examination in conjunction with adjunct investigations can help in preoperative surgical planning and in determining the need for combined or staged procedures. The eye should be quiescent for a minimum of 3 months before cataract surgery. Perioperative corticosteroid prophylaxis is important to reduce the risk of cystoid macular edema and recurrence of the uveitis. Antimicrobial prophylaxis may also reduce the risk of reactivation in eyes with infectious uveitis. Uveitic cataracts may be surgically demanding due to the presence of synechiae, membranes, and pupil abnormalities that limit access to the cataract. This can be overcome by manual stretching, multiple sphincterotomies or mechanical dilation with pupil dilation devices. In patients <2 years of age and in eyes where the inflammation is poorly controlled, intraocular lens implantation should be deferred. Intensive local and/or oral steroid prophylaxis should be given postoperatively if indicated. Patients must be monitored closely for disease recurrence, excessive inflammation, raised intraocular pressure, hypotony, and other complications. Complications must be treated aggressively to improve visual rehabilitation. With proper patient selection, improved surgical techniques and optimization of peri- and post-operative care, patients with uveitic cataracts can achieve good visual outcomes.

Abstract
BACKGROUND To evaluate the efficacy and safety of dexamethasone (DEX) implants in paediatric patients with noninfectious intermediate or posterior uveitis. METHODS Prospective single center exploratory case series. Children and adolescents, 6 to 17 years old, with a vitreous haze score of ≥1.5+ or cystoid macular edema (CME) of >300 μm were enrolled. Vitreous haze score at month 2 was chosen as primary endpoint. Best corrected visual acuity (BCVA), central retinal thickness (CRT) and concomitant medication at month 6 were defined as secondary endpoints. Intraocular pressure (IOP) and cataract formation were determined as safety endpoints. RESULTS Three out of 6 eligible patients participated in the case series. At month 2, vitreous haze was reduced from a score of 1.5+ to 0.5+ and 0 and BCVA improved by ≥3 lines, ≥4 lines and ≥2 lines of Early Treatment of Diabetic Retinopathy (ETDRS)-letters, respectively. Visual acuity gain was accompanied by a CRT reduction of -186 μm and -83 μm in the first and third patient, in whom CME was the indication for DEX implantation. A reduction of concomitant medication was achieved in 1 patient. IOP increase was seen in all 3 patients, but could be treated sufficiently with primarily IOP lowering medications and without need for glaucoma surgery. Cataract progression did not occur. CONCLUSIONS DEX implants led to an improvement in all endpoints, especially BCVA. This study confirms that IOP rises may also occur in the paediatric population and should be monitored and treated appropriately.

Abstract
There are no standardized treatment protocols for pediatric non-infectious uveitis. Topical corticosteroids are the typical first-line agent, although systemic corticosteroids are used in intermediate, posterior and panuveitic uveitis. Corticosteroids are not considered to be long-term therapy due to potential ocular and systemic side effects. In children with severe and/or refractory uveitis, timely management with higher dose disease-modifying antirheumatic drugs (DMARDs) and biologic agents is important. Increased doses earlier in the disease course may lead to improved disease control and better visual outcomes. In general, methotrexate is the usual first-line steroid-sparing agent and given as a subcutaneous weekly injection at >0.5 mg/kg/dose or 10-15 mg/m2 due to better bioavailability. Other DMARDs, for instance mycophenolate, azathioprine, and cyclosporine are less common treatments for pediatric uveitis. Anti-tumor necrosis factor-alpha agents, primarily infliximab and adalimumab are used as second line agents in children refractory to methotrexate, or as first-line treatment in those with severe complicated disease at presentation. Infliximab may be given at a minimum of 7.5 mg/kg/dose every 4 weeks after loading doses, up to 20 mg/kg/dose. Adalimumab may be given up to 20 or 40 mg weekly. In children who fail anti-tumor necrosis factor-alpha agents, develop anti-tumor necrosis factor-alpha antibodies, experience adverse effects, or have difficulty with tolerance, there is less data available regarding subsequent treatment. Promising results have been noted with tocilizumab infusions every 2-4 weeks, abatacept monthly infusions and rituximab.

Abstract
Steroid medications may cause elevation of intraocular pressure, sometimes with permanent damage to the optic nerve. These therapies, via various routes of administration, are commonly prescribed for children, but the potential sequelae of elevated intraocular pressure and glaucomatous optic nerve damage can be even more severe and devastating in children than in adults. This review discusses the pathophysiology and potential risk factors, including the impact of intraocular pressure elevation via the different common routes of administration of steroids, clinical evaluation, and management of steroid response and steroid-induced glaucoma in children.

Abstract
Cataract is one of the most common and visually debilitating complications of pediatric uveitis. It develops as a consequence of chronic inflammation and steroid use and is seen most often in juvenile idiopathic arthritis (JIA)-associated uveitis. Cataract extraction with intraocular lens (IOL) insertion has been carried out with a measure of success in non-uveitic pediatric eyes, but in cases of uveitis, multiple factors affect the final outcome. Chronic inflammation and its sequelae such as band keratopathy, posterior synechiae, and cyclitic membranes make surgical intervention more challenging and outcome less certain. Postoperative complications like increased inflammation, glaucoma, posterior capsular opacification, retrolental membranes, and hypotony may compromise the visual outcome. Early refractive correction is imperative in pediatric eyes to prevent amblyopia. The use of contact lenses and intraocular lenses in pediatric uveitic eyes were fraught with complications in the past. Surgical interventions such as vitreo-lensectomy followed by contact lens fitting and small incision cataract surgery followed by different types of intraocular lenses have been utilized, and many reports have been published, albeit in small patient groups. This review analyzes and discusses the existing literature on intraocular lens implantation in cases of pediatric uveitic cataract surgery.

Abstract
Glaucoma, the second most common cause of blindness in the world, is a multifactorial disease with several risk factors, of which intraocular pressure (IOP) is a primary contributing factor. Filtration surgery is one of the most effective means to significantly lower IOP compared to medical or laser treatments, and it is typically reserved for advanced disease. However, there are high rates of postoperative complications associated with the procedure, often from over- or under-filtration. To address these problems, the glaucoma drainage device regulator (GDDR) implant was developed to allow post-operative control of aqueous flow and IOP. The device, a tube with a nanopore membrane, is placed beneath the scleral flap. Postoperatively, the membrane surface can be ruptured with a laser to augment flow through the system. This feature allows adjustable control of aqueous flow and diminishes the risk of hypotony in the early postoperative period.

Abstract
PURPOSE To evaluate outcomes of long-term follow-up of Retisert multiple implantation and dissociation in eyes with chronic noninfectious uveitis. METHODS Review of 187 consecutive Retisert implants. Outcomes of multiple implantation and spontaneous medication pellet-strut dissociation were evaluated. RESULTS A total of 187 consecutive Retisert implants were reviewed. Eight implants were removed. The prevalence of spontaneous dissociation was 2.6% (5/187). The rate of dissociation increased to 11.11% (2/18) in cases of multiple implants. The mean period between Retisert implantation and spontaneous dissociation was 65.05 months. The mean period between implants in the same eye was 55.25 months. In cases of multiple implantations the old implant was not removed and 17.64% (3/17) of eyes required glaucoma filtering surgery. CONCLUSION The rate of spontaneous dissociation of Retisert medication pellet-strut in eyes with single implant for noninfectious uveitis is low, which tends to increase in eyes with multiple implants.

Abstract
INTRODUCTION Treatment of adult, noninfectious uveitis remains a challenge for ophthalmologists around the world. The disease accounts for almost 10% of preventable blindness in the US and can be idiopathic or associated with infectious and systemic disorders. Strong evidence is still emerging to indicate that pharmacologic strategies presently used in rheumatologic or autoimmune disease may be translated to the treatment of intraocular inflammation. Corticosteroid monotherapy is widely regarded as wholly inappropriate, due to the unfavorable risk/benefit profile and poor long-term outcomes. Treatment plans have shifted away from low-dose, chronic corticosteroid therapy for maintenance, towards medium- to high-dose therapy for acute inflammation, followed immediately by initiation of immunomodulatory therapy. These therapies follow the 'stepladder approach', whereby least to more aggressive therapies are trialed to induce remission of inflammation, eventually without corticosteroids of any form (topical, local and systemic). AREAS COVERED This two-part review gives a comprehensive overview of the existing medical treatment options for patients with adult, noninfectious uveitis, as well as important advances for the treatment of ocular inflammation. Part I covers classic immunomodulation and latest information on corticosteroid therapy. EXPERT OPINION The hazard of chronic corticosteroid use for the treatment of adult, noninfectious uveitis is well-documented. Corticosteroid-sparing therapies, which offer a very favorable risk-benefit profile when administered properly, should be substituted.

Abstract
Pediatric uveitis is a topic of special interest not only because of the unique diagnostic and therapeutic challenges but also because of the lifetime burden of vision loss if the problem is not adequately treated, as well as the economic and psychological toll on the family. Often, uveitis in children is discovered as part of a routine eye exam; this silent, insidious inflammation can be difficult to treat and can lead to further complications if not handled skillfully. Corticosteroids have long been the mainstay of therapy; however, the significant associated side effects mandate a corticosteroid-sparing therapeutic regimen in pursuit of remission. In this review, we cover the therapeutic options for pediatric uveitis, specifically focusing on the most common non-infectious varieties, juvenile idiopathic arthritis-associated uveitis and pars planitis.

Abstract
PURPOSE To report our experience using Ozurdex (Allergan, Irvine, CA), a biodegradable intravitreal implant containing of 0.7 mg of dexamethasone approved for use in adults with noninfectious uveitis in adults, in the treatment of pediatric uveitis. METHODS The medical records of consecutive patients with noninfectious posterior uveitis who were unresponsive to standard treatment and subsequently received the Ozurdex implant from March 2011 to March 2013 were retrospectively reviewed. RESULTS A total of 14 eyes of 11 patients (mean age, 10.1 years; range 4-12) received 22 Ozurdex implants during the study period. Of the 11 patients, 7 had idiopathic intermediate or posterior uveitis, 1 had sympathetic ophthalmia, 2 had juvenile idiopathic arthritis, and 1 had sarcoidosis. All patients were uncontrolled with standard treatment, including topical or sub-Tenon's or systemic corticosteriods and/or immune-modulation. Visual acuity improved after Ozurdex implant in 5 of 8 patients (63%). Intraocular inflammation was controlled or improved after 17 of 22 of implants (12 eyes [77%]). The frequency of topical corticosteroids was decreased and/or discontinued after 18 of 22 implants (12 eyes [82%]). Complications included implant migration into the anterior chamber (4 aphakic eyes), increased intraocular pressure (5 eyes), and progression of a preexisting cataract (1 eye). The uveitis reoccurred in 57% of eyes at 4.3 months (2-7 months) after injection. CONCLUSIONS The Ozurdex implant in combination with systemic immunomodulatory therapy resulted in improved visual acuity, control of intraocular inflammation, and a decrease in corticosteroid use. In the majority of eyes the uveitis reoccurred around 4 months after injection. The adverse events in our study are similar to those identified in adult studies.

Abstract
PURPOSE To describe the long-term outcome of eyes with uveitis after repeated treatment with dexamethasone implants (Ozurdex; Allergan, Inc., Irvine, CA). DESIGN Retrospective, observational case series. PARTICIPANTS Thirty-eight eyes of 27 patients with uveitis that were treated with 61 dexamethasone implants. METHODS All eyes underwent dexamethasone pellet implantation. Anatomic and functional outcomes, as well as ocular complications, were noted. MAIN OUTCOME MEASURES Best-corrected visual acuity (BCVA), central retinal thickness (CRT), vitreous haze score, and presence of increased intraocular pressure or cataract. RESULTS Average follow-up was 17.3 ± 1.8 months after the first implant (median, 13.3 months; range, 3-54.5 months; 54.65 eye-years), with 14 eyes (36.9%) receiving a single implant and 24 eyes (63.1%) receiving multiple implantations. After the first implantation, average BCVA improved significantly from 0.47 ± 0.05 logarithm of the minimum angle of resolution (logMAR) units (Snellen equivalent, 20/60) to 0.27 ± 0.07 logMAR (Snellen equivalent, 20/37; P<0.001); CRT decreased by 263 ± 44.22 μm (P = 0.003), although macular edema persisted in 50% of eyes, and the percentage of eyes achieving a vitreous haze score of 0 increased from 58% to 83% (P = 0.03). The median duration of therapeutic effect after the first injection was 6 months (range, 2-42 months), with a similar response achieved after each repeat implantation. The accumulated effect of repeat dexamethasone implants resulted in a continued improvement in BCVA (R(2) = 0.91; P<0.0001), with significant improvement and stabilization of CRT. After repeated implantations, 2 eyes had progression of posterior subcapsular opacities, although neither required surgery. There were 7 instances of increased intraocular pressure of more than 21 mmHg at a rate of 0.13 per eye-year, all of which responded to pharmacologic treatment. CONCLUSIONS The accumulated effect of repeat dexamethasone pellet implantations improves retinal thickness and resolves ocular inflammation, resulting in restoration of ocular function. Ocular complications were minimal, with no eyes requiring surgery for increased ocular pressure or progression of cataract.

Abstract
PURPOSE OF REVIEW Pediatric uveitis is relatively uncommon, accounting for only 5-10% of all patients with uveitis. However, owing to high prevalence of complications and devastating outcomes, its lifetime burden can be significant. RECENT FINDINGS Immunomodulatory therapy has been associated with better outcomes in noninfectious pediatric uveitis. However, effective treatments are limited by medication-related complications, including multiorgan toxicities and systemic side effects. SUMMARY We review the current therapies available to treat pediatric uveitis, discuss novel and future therapies, and provide clinical recommendations utilizing these new agents. The consideration for treatment regimens in noninfectious pediatric uveitis is multifactorial. Understanding past, present, and future technology will aid in treatment of a complex and refractory disease.

Abstract
Uveitis is one of the most important causes of blindness worldwide. Its etiology and pathogenesis are complicated and have not been well understood. The treatment for uveitis is predominantly based on steroids and immunosuppressants. However, systemic side effects limit their clinical application. With the advancement of molecular biology, some intravitreal implants and biologic agents have been used for the treatment of uveitis. Additionally, novel techniques such as gene therapy and RNA interference are being studied for using as uveitis therapy. This paper reviews recent advances in uveitis treatment.

Abstract
Objective To review fibrosis of fluocinolone acetonide (FA) implants in subjects with CAPN5 autosomal dominant neovascular inflammatory vitreoretinopathy (ADNIV). Methods A retrospective case series was assembled from ADNIV patients in which there was fibrotic encapsulation of a fluocinolone acetonide implant. CAPN5 genotypes and surgical repair techniques were reviewed. Results Two eyes of two ADNIV patients developed a fibrotic capsule over the fluocinolone acetonide implant. Both patients had Stage IV disease. Patient A had a c.731T > C mutation in the CAPN5 gene and patient B had a c.728G > T mutation. The fibrotic membrane was surgically excised and the implant function was restored. Conclusion The exuberant fibrotic response in later stages of ADNIV may be resistant to local immunosuppression with steroids. Surgical excision of fibrotic membranes over FA implants can reestablish local steroid delivery in cases of severe proliferative vitreoretinopathy.

Abstract
OBJECTIVE To review the effect of the fluocinolone acetonide implant in subjects with autosomal dominant neovascular inflammatory vitreoretinopathy (ADNIV), an inherited autoimmune uveitis. METHODS A retrospective case series was assembled from patients with ADNIV who received fluocinolone acetonide implants. Visual acuity and features of ADNIV, including inflammatory cells, neovascularization, fibrosis, and cystoid macular edema, were reviewed. RESULTS Nine eyes of 5 related patients with ADNIV with uncontrolled inflammation were reviewed. Follow-up ranged from 21.7 to 56.7 months. Visual acuity at implantation ranged from 20/40 to hand motion. Preoperatively, 8 eyes had vitreous cells (a ninth had diffuse vitreous hemorrhage). Eight eyes had cystoid macular edema, 7 had an epiretinal membrane, and 3 had retinal neovascularization. Following implantation, vitreous cells resolved in all eyes and neovascularization regressed or failed to develop. Central macular thickness improved in 4 eyes. During the postoperative course, however, visual acuity continued to deteriorate, with visual acuity at the most recent examination ranging from 20/60 to no light perception. There was also progressive intraocular fibrosis and phthisis in 1 case. Four eyes underwent cataract surgery. Six of the 7 eyes without previous glaucoma surgery had elevated intraocular pressure at some point, and 3 of these required glaucoma surgery. CONCLUSIONS The fluocinolone acetonide implant may inhibit specific features of ADNIV such as inflammatory cells and neovascularization but does not stabilize long-term vision, retinal thickening, or fibrosis. All eyes in this series required cataract extraction, and more than half required surgical intervention for glaucoma. Further studies may identify additional therapies and any benefit of earlier implantation.
