Lower ocular pulse amplitude with dynamic contour tonometry is associated with biopsy-proven giant cell arteritis.

Objectives: To determine the role of the ocular pulse amplitude (OPA) from Pascal dynamic contour tonometry in predicting the temporal artery biopsy (TABx) result in patients with suspected giant cell arteritis (GCA).

Design: Prospective validation study.

Participants: Adults aged 50 years or older who underwent TABx from March 2015 to April 2017.

Reactivation of Herpes Zoster Keratitis With Corneal Perforation After Zoster Vaccination.

Purpose: We present a case of reactivated herpes zoster keratouveitis of 6 years duration with corneal perforation requiring penetrating keratoplasty shortly after inoculation with herpes zoster vaccine (Zostavax, Merck, Quebec, Canada).

Methods: Retrospective case report.

Results: A 67-year-old woman with a 5-year history of recurrent unilateral herpes zoster keratouveitis in her right eye presented with another recurrence 2 weeks after Zostavax vaccination.

Secondary corneal amyloidosis after perforating corneal trauma: A series of 5 cases and review of the literature.

We retrospectively reviewed the clinical and surgical histories of 5 patients with traumatic secondary corneal amyloidosis, a relatively rare sequela of nonsurgical and surgical perforating corneal trauma. Four had history of nonsurgical trauma, and 1 had surgical trauma to the cornea. Three specimens were obtained by penetrating keratoplasties and 2 by excision of the cornea during evisceration of the ocular contents.

Usefulness of a red chromagen in the diagnosis of melanocytic lesions of the conjunctiva.

Importance: Immunohistochemical analyses may assist in the diagnosis of precancerous and cancerous conjunctival lesions.

Objective: To use Vector Red (VR) to identify an immunologic marker that is sensitive for all melanocytes and another that is sensitive and specific for activated and/or atypical conjunctival melanocytic lesions (MLs).

Design, Setting, And Participants: Eight specimens each of control lesions (normal conjunctiva and normal uvea as well as choroidal melanoma) and 8 from the diagnostic categories (conjunctival nevus, primary acquired melanosis with mild or no atypia, primary acquired melanosis with moderate to severe atypia, and conjunctival melanoma) that provided sufficient quantity and quality of tissue were available for processing.

Ocular metastasis of lung adenocarcinoma with ELM4-ALK translocation: A case report with a review of the literature.

Choroidal metastasis is the most common intraocular neoplasm and is associated with significant morbidity. In a small percentage of patients, ocular manifestation may be the initial presentation of a systemic malignancy and can be diagnostically difficult to distinguish from ocular primary malignancies. Herein, we present a case of a never-smoker whose ocular pathology was integral to the diagnosis and management of a lung adenocarcinoma harboring a rare oncogene.

Dacryops: a series of 5 cases and a proposed pathogenesis.

Importance: Lacrimal gland ductal cysts (dacryops) are uncommon, occurring anywhere that lacrimal gland tissue is present. While dacryops has long been recognized, its pathogenesis has not been well established.

Observations: Five cases of dacryops were identified at the Ottawa Hospital over a 3-year period (2009-2012).

Post-LASIK ectasia treated with intrastromal corneal ring segments and corneal crosslinking.

Corneal ectasia is a serious complication of laser in situ keratomileusis (LASIK). We report the case of a 29-year-old man who underwent LASIK in both eyes and in whom corneal ectasia developed in the left eye 3 years after surgery. He was treated sequentially with intraocular pressure-lowering medication, intrastromal corneal ring segment (ICRS) implants, and collagen cross-linking.

Bilateral necrobiotic xanthogranuloma of the eyelids followed by a diagnosis of multiple myeloma 20 years later.

A uniquely indolent case of necrobiotic xanthogranuloma with bilateral, periorbital involvement was presented. This patient presented with cutaneous eyelid lesions of 20 years' duration. Although symptomless, the patient underwent testing for hematologic malignancy, which led to a diagnosis of multiple myeloma.

Psychometric properties of a new tool to assess task-specific and global competency in cataract surgery.

Background And Objective: To establish and validate an assessment tool of cataract surgery performed by residents suitable for a competency-based curriculum.

Patients And Methods: A three-component evaluation tool was created based on review of the literature and was refined using a modified Delphi technique. Faculty surgeons viewed two videos of cataract surgery, performed by a novice and an expert, and completed the evaluation tool.

Deaf children with autism spectrum disorders.

Epidemiological studies investigating the prevalence of autism have increased in recent years, within the United States and abroad. However, statistics as to how many of those children may also have a comorbid hearing loss is lacking. The prevalence of school-administrator reported diagnosis of autism spectrum disorders (clinical diagnosis [DSM-IV] and/or IDEA classification) among children with hearing loss in the US was estimated from the 2009–2010 Annual Survey of Deaf and Hard of Hearing Children and Youth conducted by the Gallaudet Research Institute.

Bilateral benign reactive lymphoid hyperplasia of the conjunctiva in a pediatric patient.

A 13-year-old boy presented with asymptomatic, bilateral, nasal bulbar conjunctival lesions. Excisional biopsy of the larger lesion showed a mature, mixed lymphocytic infiltrate with germinal centers, consistent with a diagnosis of benign reactive lymphoid hyperplasia, a rare condition in children.

First report of Gordonibacter pamelaeae bacteremia.

We report the first case of Gordonibacter pamelaeae bacteremia, identified by phenotypic tests and 16S rRNA sequencing in a patient with disseminated rectosigmoid carcinoma and responsive to amoxicillin-clavulanate. The bacterium was a nonsporulating, anaerobic, gram-positive, nonmotile, coccobacillus that was catalase, arginine dihydrolase, and arginine acrylamidase positive. The gastrointestinal tract is probably its reservoir.
