REVIEW
Michael W Stewart
PURPOSE OF REVIEW: Ophthalmologic conditions were among the earliest described findings in patients with the acquired immunodeficiency syndrome (AIDS). The purpose of this review is to highlight recent changes in the pathophysiology and management of ophthalmologic conditions in patients infected with the human immunodeficiency virus (HIV). RECENT FINDINGS: The introduction of highly active antiretroviral therapy (HAART) in 1996 changed ophthalmologic findings from predominantly acute infectious diseases to chronic, slowly progressive, debilitating conditions...

Infectious retinitis postfebrile illness is known to be caused by chikungunya, dengue, West Nile virus, Bartonella, Lyme's disease, Rift Valley fever, rickettsia, Herpes viruses etc. Rickettsia is Gram-negative bacteria transmitted by arthropods vectors. Ocular involvement is common including conjunctivitis, keratitis, anterior uveitis, panuveitis, retinitis, retinal vascular changes, and optic nerve involvement. Retinitis lesions in rickettsia can occur because of an immunological response to the bacteria or because of direct invasion and proliferation of bacteria in the inner retina...

PURPOSE: Diagnosis of uveitis is difficult. Etiologic investigations should take into account the epidemiology of uveitis and should focus on the most severe forms of the disease and those which can be treated. This study was undertaken to establish recommendations for the diagnosis of uveitis. METHODS: Recommendations were developed by a multidisciplinary panel of 14 experts, including internists, ophthalmologists, and rheumatologists, and are based on a review of the literature and the results of the ULISSE study, which was the first prospective study to assess the efficacy of a standardized strategy for the etiologic diagnosis of uveitis...

PURPOSE: To identify the clinical features and prognostic factors of uveitis associated with ankylosing spondylitis (AS). METHODS: This retrospective, interventional case series study reviewed the medical records of 91 AS patients with uveitis. RESULTS: The characteristics of AS-associated uveitis included male preponderance (70%), average onset in the fourth decade, unilateral manifestation (87.9%), and vitreous involvement or retinal vascular leakage (36...

BACKGROUND: Optical coherence tomography angiography (OCTA) employs a novel imaging algorithm that detects the amplitude or phase decorrelation of blood cell movement. It thus provides a flow map with depth-resolved visualization of the various vascular layers in the posterior pole of the eye including the retina capillary plexus and the choroid. In the past 3 years, the number of research papers on the subject of OCTA in retinal diseases has grown exponentially including important applications in the field of uveitis...

PURPOSE: To evaluate golimumab (GOL) efficacy in the management of Behçet's disease (BD)-related uveitis. METHODS: We retrospectively collected data from 5 patients (8 eyes) with at least two recent relapses of uveitis, treated with GOL at the standard dose of 50 mg every 4 weeks. RESULTS: A complete control of intraocular inflammation was observed in 7/8 eyes (87.5%) at 12-month follow-up. The number of relapses 12 months before and after GOL initiation was 11 and 1, respectively...

Purpose: To analyze retinal thickness (RT) and choroidal thickness (ChT) changes in patients with unilateral nongranulomatous acute anterior uveitis (AAU) using three-dimensional (3D) 1060-nm optical coherence tomography (OCT). Methods: Retinal and choroidal thickness maps were statistically analyzed for 24 patients with newly diagnosed unilateral AAU before therapy. A total of 17 patients were followed until resolution of inflammatory activity (twice in the first week, then weekly)...

Posterior uveitis is an ocular complication that can occur with reactivation of varicella-zoster virus (VZV). It may lead to loss of vision due to retinal detachment and chronic inflammation, which often causes more severe disease than the virus infection itself. To increase our understanding of the immune response, we infected the retinal pigment epithelial (RPE) cell line, ARPE-19, with cell-associated VZV and compared its response to that of the MeWo cell line using multiplex assays. We observed a difference in the magnitude and kinetics of cytokine responses between the two cell types, and differential migration of CD4+ and CD8+ T cells towards these cytokines...

In addition to its conventional roles in the innate immune system, complement has been found to directly regulate T cells in the adaptive immune system. Complement components, including C3, C5, and factor D, are important in regulating T cell responses. However, whether complement component C4 is involved in regulating T cell responses remains unclear. In this study, we used a T cell-dependent model of autoimmunity, experimental autoimmune uveitis (EAU) to address this issue. We compared disease severity in wild-type (WT) and C4 knockout (KO) mice using indirect ophthalmoscopy, scanning laser ophthalmoscopy, spectral-domain optical coherence tomography, and histopathological analysis...

AIM: To study patterns of uveitis in Indian children and compare with data sets published earlier in the literature. METHODS: Consecutive patients below 16 years of age presenting to the uvea clinic of a tertiary eye care center were included prospectively through the period of July 2009-August 2013. Children with retinal vasculitis, exogenous endophthalmitis and masquerade syndromes were excluded from analysis. Uveitis was classified as per the nomenclature system adopted by the International Uveitis Study Group...

Sustained-release intravitreal 0.7 mg dexamethasone (DEX) implant is approved in Europe for the treatment of macular edema related to diabetic retinopathy, branch retinal vein occlusion, central retinal vein occlusion, and non-infectious uveitis. The implant is formulated in a biodegradable copolymer to release the active ingredient within the vitreous chamber for up to 6 months after an intravitreal injection, allowing a prolonged interval of efficacy between injections with a good safety profile. Various other ocular pathologies with inflammatory etiopathogeneses associated with macular edema have been treated by DEX implant, including neovascular age-related macular degeneration, Irvine-Gass syndrome, vasoproliferative retinal tumors, retinal telangiectasia, Coats' disease, radiation maculopathy, retinitis pigmentosa, and macular edema secondary to scleral buckling and pars plana vitrectomy...

CLINICAL CASE: A young woman was referred to our offices with impairment of visual acuity after she received a third tattoo on her arm. Systemic medical and laboratory work-up were performed in order to exclude an infectious agent or inflammatory disease. A yellowish juxtafoveal lesion in left eye along with a plaque-like outer retinal disruption and focal pigmentary defects was assessed using multi-modal diagnostic imaging. DISCUSSION: Ophthalmologists treating uveitis should consider this uncommon association and question patients regarding tattoos and tattoo inflammation given the rise of subjects undergoing artistic tattooing...

In 2015, the Centers for Disease Control and Prevention (CDC) and the American Academy of Ophthalmology (AAO) released clinical advisories on rising cases of ocular syphilis. We examined the association between eye disease and syphilis infection among primary care and sexually transmitted infection (STI) clinic patients attending an urban lesbian, gay, bisexual, transgender (LGBT) health center. We conducted a retrospective medical record review of all patients who underwent syphilis testing at Howard Brown Health between 1 January 2010 and 31 December 2015...

PURPOSE: Report a case of concurrent unilateral optic neuritis and central retinal artery occlusion as the presenting signs of syphilis. METHODS: A case report of a 22-year-old man with progressive unilateral vision loss. RESULTS: With no known previous history of syphilis, genital lesions, or other extraocular manifestations, the patient presented with pain with eye movements and decreased color vision. His vision dramatically worsened after a course of oral steroids...

PURPOSE: Corticosteroids remain the mainstay therapy for uveitis, a major cause of blindness in the working age population. However, a substantial number of patients cannot benefit from the therapy due to steroids resistance or intolerance. Tacrolimus has been used to treat refractory uveitis through systemic administration. The aim of this study was to evaluate the therapeutic potential of 0.03% tacrolimus eyedrop in mouse models of uveitis. METHODS: 0.03% tacrolimus in perfluorobutylpentane (F4H5) (0...
