#1
REVIEW
Frederik Holm Svendsen, Steffen Heegaard
Lymphoma of the eyelid constitutes 5% of ocular adnexal lymphoma. In previously published cases, 56% of lymphomas of the eyelid are of B-cell origin and 44% are of T-cell origin. The most frequent B-cell lymphomas are extranodal marginal zone lymphoma (27 cases--14%) and diffuse large B-cell lymphoma (18 cases--9%). T-cell lymphomas are most frequently mycosis fungoides (25 cases--13%), extranodal NK/T-cell, nasal type lymphoma (12 cases--6%) and primary cutaneous anaplastic large cell lymphoma (12 cases--6%)...

REVIEW

Drugs across many pharmacologic classes induce corneal epithelial changes. Many of these drugs have cationic amphiphilic structures, with a hydrophobic ring and hydrophilic cationic amine side chain that allow them to cross cell membranes. These drugs lead to intracellular phospholipid accumulation, often manifested in the cornea by vortex keratopathy, with no effect on visual acuity and few ocular symptoms. Other drugs, notably antineoplastic agents, produce a fine diffuse corneal haze, sometimes accompanied by decreased vision that can be dose limiting...

Intraocular leiomyomas are uncommon and usually occur in the ciliary body. Primary leiomyoma of the iris is both rare and a difficult diagnosis to make, given melanocytic tumors are more common and may be amelanotic. The somewhat controversial diagnosis of iris leiomyoma requires further confirmation by immunohistochemistry and electron microscopy. Herein, we describe 58-year-old man with a 2 mm round translucent pink lesion of the iris. The tumor was excised by sector iridectomy. Immunohistochemistry showed positivity for both smooth muscle actin and desmin and negativity for S-100, HMB45, SOX10, Melan A, CD31, CD34 and h-caldesmon...

Though the connection is not often apparent, hepatic pathology may be associated with ophthalmic disease . We review the literature concerning the periocular, periorbital, and orbital manifestations of various hepatic disorders. This includes periocular/periorbital jaundice, the impact of hepatitis B and C, eyelid changes in cirrhosis, orbital mass lesions in hepatocellular carcinoma, and cutaneous vascular malformations as they are related to liver disease. The motility disorders associated with Wilson's disease, the ophthalmic manifestations of Alagille syndrome, and the effects of liver transplantation are also discussed...

REVIEW

PURPOSE: The diagnosis of limbal stem cell deficiency (LSCD) is often based on clinical manifestations with or without the use of tests to demonstrate the presence of goblet cells or of specific epithelial markers on the corneolimbal surface. This systematic review looks at the various diagnostic methods employed in the diagnosis of LSCD in published interventional studies. DESIGN: Systematic literature review METHODS: We did a systematic search on MEDLINE and PUBMED for articles published in English between January 1, 2003 and December 31, 2013...

A 48-year-old man presented with a longstanding left upper eyelid mass that increased in size when bending forward. The mass was associated with enophthalmos and slowly increased in size with Valsalva maneuver. Magnetic resonance imaging and arteriography demonstrated a vascular malformation without an abnormal arterial component. Because of his increasing pain, the vascular malformation was excised in a multidisciplinary approach involving intraoperative fluoroscopic mapping, cyanoacrylate embolization and surgical excision...

REVIEW

Acanthamoeba keratitis (AK) is a sight-threatening infectious disease. Resistance of the cystic form of the protozoan to biocides and the potential toxicity of chemical compounds to corneal cells are the main concerns related to long-term treatment with the clinically available ophthalmic drugs. Currently, a limited number of recognized antimicrobial agents are available to treat ocular amoebic infections. Topical application of biguanide and diamidine antiseptic solutions is the first-line therapy. We consider the current challenges when treating AK and review the chemical properties, toxicities, and mechanisms of action of the available biocides...

Cryptococcal meningitis is the most common and severe form of cryptococcal infection. In addition to infiltrative and inflammatory mechanisms, intracranial hypertension commonly complicates cryptococcal meningitis and may cause significant visual and neurological morbidity and mortality. The mainstays of treatment for cryptococcal meningitis include standard antifungal therapy, management of intracranial hypertension, and treatment of underlying immunosuppressive conditions. Early and aggressive management of intracranial hypertension in accordance with established guidelines reduces the risk of long-term visual and neurological complications and death...

Punctate Inner Choroidopathy (PIC), an idiopathic inflammatory multifocal chorioretinopathy that predominantly affects young myopic women, appears to be relatively rare, but there is limited data to support accurate estimates of prevalence, and it is likely that the condition is under-diagnosed. The etiological relationship between PIC and other conditions within the 'white dot syndromes' group remains uncertain. We, like others, would suggest that PIC and multifocal choroiditis with panuveitis (MCP) represent a single disease process that is modified by host factors (including host immunoregulation) to cause the range of clinical phenotypes seen...

Argyrios Chronopoulos, Gabriele Thumann, James Schutz
Positive vitreous pressure (PVP) occurs during anterior segment intraocular surgery associated with acute hypotony and is characterized by forward displacement of the lens-iris diaphragm with shallowing of the anterior chamber resistant to reformation, repeated iris prolapse, and, in severe cases, zonular rupture and vitreous or lens prolapse that can lead to a cascade of intraoperative complications. PVP is particularly common during penetrating keratoplasty (PK), conventional nuclear expression cataract extraction, and repair of anterior open globe injury...

Parasitic infections of the eyes are a major cause of ocular diseases across the globe. The causative agents range from simple organisms such as unicellular protozoans to complex metazoan helminths. The disease spectrum varies depending on the geographic location, prevailing hygiene, living and eating habits of the inhabitants, and the type of animals that surround them. They cause enormous ocular morbidity and mortality not because they are untreatable, but largely due to late or mis-diagnosis, often from unfamiliarity with the diseases produced...

Amir Cohen, Sze H Wong, Shriji Patel, James C Tsai
Endoscopic cyclophotocoagulation (ECP) is laser treatment of the ciliary processes with direct visualization using a small video camera for the purpose of lowering intraocular pressure. It was traditionally reserved for management of refractory glaucoma, but is now increasingly used as an adjunct to cataract surgery in less advanced glaucoma. Here, we present a review of the literature evaluating ECP's safety and efficacy in different forms of glaucoma with different degrees of progression.

Synovial sarcoma (SS) is a soft tissue sarcoma of the extremities developing in young adults that has rarely been reported in the orbit. SS is associated with a unique translocation, resulting in an SYT-SSX fusion gene. We analyze seven published periocular cases, together with the current one, to gain a better appreciation of the features of the tumor in this location and to compare the findings with those derived from non-ophthalmic studies. A 31-year-old woman developed an inferior orbital mass after experiencing periorbital and hemifacial pain for more than a decade...

Advancements in technology and medicine have led to a greater life expectancy and a corresponding increased interest in the mechanisms and prevention of aging. Because of its central role in human perception of age and emotion, the aging face generates a high demand for understanding the etiology of senescence-related changes. There are effective nonsurgical and surgical methods available for those seeking functional or cosmetic facial rejuvenation.

REVIEW
J Daniel Diaz, Ethan K Sobol, David C Gritz
Scleral inflammatory disorders, with their extensive differential diagnoses and sometimes as controversial treatment options, pose both diagnostic and clinical challenges for physicians. Targeted laboratory investigations derived from careful history taking and physical examination are crucial in the early identification of patients with associated systemic conditions. Prompt discrimination between episcleritis and scleritis is of therapeutic importance, as management, prognosis, and complications differ for these diseases...
