#1
Jonathan J Dutton, Alan D Proia
PURPOSE: Seminomas are solid tumors in young men, but which rarely metastasize to the orbit. The authors review the known literature on seminoma metastatic to the orbit, and describe an additional case in a 33-year-old man. METHODS: A literature search was performed on the MEDLINE database using keywords "seminoma," "testicular germ-cell tumors," "testicular cancer," "testicular neoplasm," "orbital metastasis," and "germ-cell neoplasms." RESULTS: Malignant neoplasms of the testis account for only 1% of cancers in men...

PURPOSE: To study whether ethmoidectomy predisposes the orbit to medial wall fracture with lesser trauma. METHODS: An interventional cadaver study of 5 heads (10 orbits); the left or right orbit was randomized to undergo endoscopic complete ethmoidectomy with the fellow orbit as control. Fractures were induced with direct globe trauma, and heads underwent CT scanning. Energy to induce fracture, peak orbital pressure at time of fracture, fracture pattern, and volume of herniated tissue were measured and analyzed...

PURPOSE: We present a novel technique to directly measure the eyelid upward force generation. This technique can be used during routine clinical examination using an inexpensive, portable force gauge. METHODS: This prospective case series was conducted January to June 2015 in an ophthalmology clinic affiliated with a tertiary care medical center. A convenience sample of 42 patients (40-90 years of age) without known eyelid pathology participated. The eyelid upward net force generated was measured directly using a handheld dynamometer noninvasively attached to the upper eyelid...

Barber-Say syndrome is a rare autosomal dominant disease characterized by dysmorphic features, mainly of the eyelids and skin. It is caused by heterozygous mutations in gene TWIST2, localized in chromosome 2q37.3. The authors present the case of a pediatric patient with a clinical diagnosis of Barber-Say syndrome with ocular symptoms related to exposure keratitis. Molecular analysis of her DNA revealed a mutation on TWIST2 gene confirming the diagnosis of Barber-Say syndrome. Surgical treatment of the patient's eyelids resolved her signs and symptoms...

Lateral bony decompression may offer several biomechanical advantages and has become a commonly used surgical approach. Preoperative imaging plays a key role in surgical planning by providing information about the locoregional anatomy. The marrow space of the greater wing of the sphenoid is a focal point of the decompression surgery based on the volume that it occupies. Several vessels pass through the sphenoid bone, but most are small caliber vessels. The authors describe a case of an uncommon anatomical variant of the cranial diploic venous system in which the anterior transverse diploic vessel traverses the marrow space of the sphenoid...

Koebner phenomenon is the development of isomorphic pathologic lesions on a wound of a patient with preexisting cutaneous disease, most commonly psoriasis. An elderly male with palmoplantar psoriasis developed periocular psoriasis in the form of blepharitis and conjunctivitis following an external dacryocystorhinostomy as a manifestation of Koebner phenomenon. Immediate diagnosis and treatment with topical steroids led to complete recovery. Thus, the authors report the first case of Koebner phenomenon in ophthalmic literature, with a review of previously published postsurgical cases of Koebnerization in psoriasis patients...

The immune reconstitution inflammatory syndrome is an exaggerated abnormal immune response, typically seen in HIV-positive patients following restoration of a normal CD4 count as a result of initiation of antiretroviral therapy. It has been described in relation to either occult opportunistic infections or to a paradoxical relapse of a previously successfully treated infection with negative microbiological cultures. The authors report the case of a 60-year-old HIV-positive African male who presented with 2 episodes of orbital inflammation that occurred in conjunction with improvements of CD4 count following Highly Active Antiretroviral Therapy...
