Keratolenticular dysgenesis (KLD) and ectopia lentis are congenital eye defects. The aim of this study is the identification of molecular genetic alterations responsible for those ocular anomalies with neurologic impairment in an individual with a de novo balanced chromosome translocation t(11;18)(q23.3;q11.2)dn. Disruption of OAF, the human orthologue of the Drosophila oaf, by the 11q23.3 breakpoint results in reduced expression of this transcriptional regulator. Furthermore, four most likely nonfunctional chimeric transcripts comprising up to OAF exon 3, derived from the der(11) allele, have also been identified...

Purpose: To report a case of marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) in the bilateral orbit with chronic hepatitis B virus (HBV) infection. Observations: A 72-year-old man with chronic HBV infection presented with a bilateral proptosis with slight restriction of ocular motility for 9 months. Computed tomographic images showed well-defined, isodense masses in the bilateral superolateral orbit. Magnetic resonance images showed isointense on T1-and hyperintense on T2-weighted images, with bilateral involvements of the lateral rectus muscles reaching the superior orbital fissures...

To summarize actual knowledge on epidemiology, etiology, pathology, clinical apparence and treatment of ocular surface squamous neoplasias. We summarize up-to-date literature on conjunctival intraepithelial neoplasia and invasive squamous cell carcinoma and present some own cases. Ocular surface squamous neoplasia is the most common malignant ocular surface tumor and the third most common ocular malignancy following malignant melanoma and lymphoma. In spite of its low malignant potential, in advanced stages it may reduce visual acuity significantly or even the eye globe has to be removed...

Extranodal marginal zone lymphoma (EMZL), mostly represented by mucosa-associated lymphoid tissue (MALT) type, also referred to as MALT lymphoma, is a clinically heterogeneous entity within the group of low-grade B cell lymphomas that arises in a wide range of different extranodal sites, including the stomach, lung, ocular adnexa, and skin. It represents the third most common non-Hodgkin lymphoma in the Western world, and the median age of occurrence is around 60 years. One characteristic aspect in a subset of EMZL detectable in about 25% of the cases is the presence of specific chromosomal translocations involving the genes MALT1 and BCL10, which lead to activation of the NF-κB signaling pathway...

Horner's Syndrome (HS) is a neurological syndrome characterised by the triad incomplete pupillary miosis, palpebral ptosis and facial anhidrosis, due to a lesion of the oculosympathetic pathway, formed of three neurons from the hipothalamus to the eye. Identifying its cause is a diagnostic challenge since in spite of its apparent lack of clinical importance, HS can be the first or only manifestation of a serious, or even potentially mortal disorder. We present the case of a 19-year-old male patient with a history of nonspecific ocular pains of two months evolution...

A very large number of disorders affect the orbit, and many of these occur in the setting of systemic disease. This lecture covers selected aspects of orbital diseases with systemic associations in which the author has a particular clinical or research interest. Spontaneous orbital haemorrhage often occurs in the presence of bleeding diatheses. Thrombosis of orbital veins and ischaemic necrosis of orbital and ocular adnexal tissues occur with thrombophilic disorders, vasculitis, and certain bacterial and fungal infections...

The etiology of sarcoidosis is still obscure; however, Mycobacteria and Propionibacterium acnes are considered the most implicated etiological agent for sarcoidosis. To investigate whether P. acnes is an etiological agent for sarcoid uveitis, we analyzed the frequency of P. acnes detected within the biopsied retinas from patients with ocular sarcoidosis by immunohistochemistry with a P. acnes-specific monoclonal antibody (PAB antibody). Eleven patients (12 eyes) with sarcoid uveitis were enrolled in this study...

INTRODUCTION: Currently, the detection of pathogens or mutations associated with intraocular lymphomas heavily relies on prespecified, directed PCRs. With metagenomic deep sequencing (MDS), an unbiased high-throughput sequencing approach, all pathogens as well as all mutations present in the host's genome can be detected in the same small amount of ocular fluid. METHODS: In this cross-sectional case series, aqueous fluid samples from two patients were submitted to MDS to identify pathogens as well as common and rare cancer mutations...

BACKGROUND: Herpes uveitis has been previously reported to present with hyphema, but hemorrhagic hypopyon is rarely reported as a herpetic uveitis manifestation. We report a case of herpes simplex virus (HSV) presenting with hemorrhagic hypopyon, and speculate on the underlying pathophysiology with relation to an intravascular lymphoma which was subsequently diagnosed as a result. CASE PRESENTATION: We present a case wherein a 62-year-old Japanese rheumatoid arthritis woman, with HSV uveitis, presented with hemorrhagic hypopyon in the anterior chamber and a fever with photophobia...

The past two decades has been an amazing time in the advancement of cancer treatment. Molecularly targeted therapy is a concept in which specific cellular molecules (overexpressed, mutationally activated, or selectively expressed proteins) are manipulated in an advantageous manner to decrease the transformation, proliferation, and/or survival of cancer cells. In addition, increased knowledge of the role of the immune system in carcinogenesis has led to the development of immune checkpoint inhibitors to restore and enhance cellular-mediated antitumor immunity...

Primary ocular lymphomas are typically confined to either the eye or the orbit. Rarely, in immune-competent patients, lymphomas affect both the eye and the orbit simultaneously. Mucosa-associated lymphoid tissue (MALT) lymphomas are the most common ocular lymphomas. They usually present primarily in the orbit but sometimes can present primarily in intraocular tissue. MALT lymphomas that occur initially in the uvea can sometimes spread to the adjacent orbit. We report a case of progressively enlarging MALT lymphoma in a 62-year-old immune-competent patient causing a severe mass effect in the orbit and simultaneously presenting with intraocular involvement...

The eye and the ocular adnexae are rare sites for malignant non-Hodgkin lymphoma (NHL). Based on their anatomical location, intraocular lymphomas must be discerned from NHL of adnexal structures including conjunctiva, lacrimal gland, and orbit. Whereas the latter group mostly consists of indolent extranodal marginal zone B‑cell lymphomas of mucosa-associated lymphoid tissue (MALT) type or secondary manifestations of systemic NHL, most primary intraocular lymphomas are classified as diffuse large B‑cell lymphomas (DLBCL) and are considered a variant of primary DLBCL of the central nervous system...

BACKGROUND: Radiotherapy is a commonly used treatment for limited-stage ocular adnexal mucosa-associated lymphoid tissue lymphoma (OAML) but showed a substantial relapse risk if the disease involves beyond-conjunctiva or bilateral conjunctivae. Systemic chemoimmunotherapy may be an alternative frontline therapy for the limited disease with those adverse prognostic factors. PATIENTS AND METHODS: We designed a multicenter, phase II study of the chemoimmunotherapy, rituximab, cyclophosphamide, vincristine, and prednisolone (R-CVP) for the treatment of patients with limited-stage OAML with bilateral or beyond-conjunctival involvement...

Koala retrovirus (KoRV) infection, thought to be associated with lymphoid neoplasia, and Chlamydia pecorum-related ocular and urogenital disease are both highly prevalent in eastern Australian koala (Phascolarctos cinereus) populations. However, in South Australian koalas, little is known about KoRV infection and C. pecorum-associated disease. We report the first South Australian case of lymphoma in a KoRV-A-positive female koala also affected by severe reproductive chlamydiosis. The koala was from the Mount Lofty Ranges population and was presented with hindlimb lameness...

Ocular adnexal lymphomas are a group of heterogeneous neoplasms representing approximately 1-2% of non-Hodgkin lymphomas and 8% of extranodal lymphomas. The incidence of primary ocular adnexal lymphoid tumors has raised over the last decades, and this could be probably attributed to the more sophisticated diagnostic techniques. Due to the wide spectrum of clinical manifestations, ocular tissue biopsy is important in order to set a precise diagnosis based on histological, immunophenotypical and, in some cases, molecular findings...
