Despite recent progress, the diagnosis of primary CNS lymphoma (PCNSL) remains a challenge and is often delayed by several months. Treatment options are still debated and the prognosis of PCNSL lymphoma is poor for most patients. This review will describe recent progress and future orientations for diagnosis of PCNSL and report on the recent trends regarding therapeutic options.

PCNSL must be suspected in cases of chronic posterior uveitis, especially in patients over 50 years old. Diagnosis is based on cytology and molecular analysis of clonality of vitreous samples. Intraocular interleukin (IL)-10 level has proved to be a valuable tool for screening purposes in cases where there is a suspicion of primary vitreoretinal lymphoma. Intraocular cytokine dosage could also be a useful marker to follow the therapeutic response of patients with PCNSL. Treatment of PCNSL remains under debate.

Diagnosis of PCNSL is challenging. Suspicion relies on clinical history and on IL-10 and IL-6 levels in ocular fluid samples. Definite diagnosis is based on cytology and molecular analysis of clonality. New diagnostic and prognostic markers are currently evaluated. Whether isolated vitreoretinal lymphoma should be treated locally or with systemic treatment remains highly controversial.

The purpose of this review is to outline agents currently in use for the local anti-inflammatory therapy of ocular Adamantiades-Behçet's disease (ABD), as well as those in translation from the laboratory to clinical use.

Novel formulations and innovative intraocular delivery strategies have been recently applied to treat intraocular inflammation in ABD.

ABD is a chronic multisystemic vasculitic disease with the highest prevalence in the Mediterranean basin and in the Eastern region of Asia. Bilateral autoimmune uveitis, oral and genital aphthous and skin lesions are the historically described triad. Vorinostat ABD uveitis is chronic relapsing and often sight-threatening and, according to the actual guidelines, to limit posterior segment involvement and prevent visual impairment high-dose and long-term systemic anti-inflammatory treatment is indicated. Corticosteroids, both topically and systemically, are the most effective treatment in the acute phase. To overcome the well known side-effects of corticosteroids oveown side-effects of corticosteroids over the long period, steroid-sparing drugs have been systemically administered showing positive results but having limited safety profile. To potentiate the intraocular pharmacological efficacy of these molecules in refractory ABD uveitis and to circumvent the risks of systemic administration, novel topical and intravitreal formulations and innovative delivering systems have been recently developed.
IgG4-related disease (IgG4-RD) is a systemic process that can cause significant orbital disease. It can affect both sexes and all ages, with irreversible consequences if left untreated. Diagnosis is currently based upon a combination of clinical and imaging evidence of tissue swelling or mass, serum evidence of elevated IgG4 levels and histopathologic evidence of inappropriate IgG4 presence. The cause of IgG4-RD is as of yet unclear; this lack of understanding and the dearth of prospective studies have limited our ability to manage patients effectively. In this review, we discuss the most recent published evidence regarding best-practice management of IgG4-related orbital disease.

Recent literature remains retrospective, and has focused on the use of corticosteroid therapy as a first-line treatment. Rituximab infusions have also received significant attention, among other second-line agents. Radiation therapy has been reported to be effective. Long-term monitoring for relapse, involvement of other organ systems and potential neoplastic transformation is required.

The management of orbital IgG4-RD will gain from more targeted therapy in the future as the underlying cause is better understood. In the meantime, randomized, controlled trials of varying treatment regimens would be of benefit.

Sjögren's syndrome affects exocrine glands leading to a dry mouth and dry eyes. Dry eye manifestations can precede the diagnosis of Sjögren's syndrome by many years. Innumerous spontaneous and inducible Sjögren's syndrome models have been used to study the pathogenesis of Sjögren's syndrome. This review focuses on recent human data, ocular and extraglandular manifestations of animal models, what is known, what is still unknown and how we need to look, and their correlation correspondence to human disease.

Hallmarks of dry eye in Sjögren's syndrome include increased corneal staining, goblet cell loss and low tear volume. Confocal microscopy and impression cytology are able to clarify new markers of the ocular disease. Extraglandular manifestations should be an alert more severe complications in the eye. Some models have strong sex and exocrine gland predilection, whereas aging generally worsens the disease phenotype. Although most models do not display a significant increase in corneal staining or tear secretion impairment, conjunctival infiltration and decrease in goblet cells are frequently seen.

We have seen great advances in the role of inflammation in ocular, oral and extra-glandular manifestations of Sjögren's syndrome. Several mechanisms and mediators of Sjögren's syndrome have been elucidated in animal model studies.

Neuromyelitis optica (NMO) is an antibody-mediated inflammatory disease of the central nervous system with a predilection for the optic nerves, spinal cord and certain brain regions. It has a distinct pathogenesis relating to aquaporin-4 autoimmunity and complement-mediated injury. This knowledge has translated into targeted efforts to develop novel, disease-specific treatments. In this review, we discuss evidence supporting the use of currently available treatments for acute exacerbations and for long-term disease modification. We also discuss the risks and benefits of available and emerging immunotherapies.

Early, accurate diagnosis of NMO with appropriate acute and long-term immunosuppressive treatment is of prime importance for the prevention of disability associated with this disease. Standard measures for the management of acute exacerbations include intravenous methylprednisolone and plasmapheresis. First-line, long-term immunotherapies for NMO include azathioprine, mycophenolate mofetil and rituximab. Three randomized controlled treatment trials evaluating these agents are currently being conducted. In addition, there are numerous emerging therapies that are based upon current understanding of the disease immunopathogenesis.

NMO is an autoimmune disease that is separate from multiple sclerosis. Better understanding of its antibody and complement-dependent pathophysiology has proven to be critical for the formulation of current and future treatment strategies.

The purpose of this review was to provide an overview of current data on antibiotic prophylaxis in ocular toxoplasmosis.

Studies showing the prophylactic effect of long-term antibiotics are discussed. Prophylaxis seems to be justified in patients with a high risk of recurrence because of antibiotic's potential side-effects. Therefore, predisposing factors leading to a higher risk of recurrence and the time period during which an antibiotic prophylaxis is most appropriate are reviewed. Finally, a patient-individualized treatment recommendation is summarized.

In the current literature, two prospective, randomized case-control studies exist, which show the protective effect of an antibiotic prophylaxis. Hematologic, gastrointestinal and dermatologic complications are potential side-effects. Especially during the first year after suffering a recurrence, an antibiotic prophylaxis seems to be justified. The risk of a recurrence is inter alia influenced by the duration of the disease, the immune status of the ised immune system. This should be discussed with each patient individually, especially if the lesion is close to the macula.
Optic neuritis is the most common cause of optic neuropathy in young adults. High-dose intravenous corticosteroids (IVCS) were established as the standard of treatment for acute optic neuritis via the Optic Neuritis Treatment Trial (ONTT), with its first findings published more than 20 years ago. Subsequent studies have further clarified the role of corticosteroids in the treatment of acute optic neuritis.

Recent clinical research has confirmed existing knowledge of the efficacy and limitations of corticosteroids in the treatment of optic neuritis. Recent studies have examined the role of race, route of administration and combination of IVCS with other therapies. Current evidence continues to support high-dose IVCS as the cornerstone of treatment of acute optic neuritis.

High-dose IVCS are effective in hastening visual recovery in acute typical optic neuritis, but do not affect the final visual outcome. In optic neuritis patients, IVCS may delay progression to clinically definite multiple sclerosis (CDMS) at 2 years, but not at 5 or 10 years. It is reasonable to recommend high-dose IVCS for acute optic neuritis patients with significant vision loss, severe pain and/or white matter lesions on brain MRI in whom the potential for benefit outweighs the risks.

Many patients suffer from the ocular manifestations associated with systemic lupus erythematosus (SLE). Retinal vasculitis and optic neuritis are two of the most vision-threatening complications that can be associated with the disease. Ocular manifestations are often associated with wide-spread systemic inflammation which can be fatal. Thus, immediate recognition and treatment is vital for a positive outcome.

There is an array of medications available to ophthalmologists for treating the ocular manifestations of SLE. Treating the underlying systemic disease is crucial, as well as treating the active ocular complications. Recently, more attention has been placed on evaluating biologic agents' efficacy in treating the systemic condition. New therapies continue to emerge that have the potential to provide benefit to patients suffering from SLE.

SLE is a serious systemic condition that may first present with ocular manifestations. Thus, it is crucial for ophthalmologists to be equipped with the knowledge to detect and adequately treat the disorder to avoid vision/life-threatening complications.
