Atypical Fibroxanthoma of the Bulbar Conjunctiva: A Unique Case Describing the Pathology, Clinical Presentation, and Management.

Background/aims: Atypical fibroxanthoma is an uncommon tumor that usually occurs in the skin of the head and neck of the elderly with significant sun exposure. We describe a unique case featuring a rare ocular surface conjunctival tumor (atypical fibroxanthoma) and provide insight on its characteristic clinical features, surgical management, and histology.

Methods: A 71-year-old male fisherman with no pertinent ocular history presented to an academic center with a rapidly enlarging bulbar conjunctival mass in the right perilimbal region for the past several months.

Measurement of Perceived Stress in Age-Related Macular Degeneration.

Purpose: To validate the Perceived Stress Scale (PSS) in patients with age-related macular degeneration (AMD) using Rasch analysis.

Methods: Study participants with AMD were recruited from the retina service of the Department of Ophthalmology at the Ohio State University during clinical visits for treatment or observation. Visual acuity with habitual distance correction was assessed.

Tear lipid layer thickness with eye drops in meibomian gland dysfunction.

Purpose: The aim of this study was to evaluate the efficacy of a lipid containing emollient eye drop, Soothe XP, which was reformulated in 2014 with a more stable preservative and buffer system, compared to a control, non-emollient, eye drop (Systane Ultra) in improving lipid layer thickness (LLT) in subjects with dry eye due to meibomian gland dysfunction (MGD).

Patients And Methods: This prospective single-center, open-label, cross-over, examiner masked-study enrolled subjects aged 30-75 years with lipid-deficient dry eye and a clinical diagnosis of MGD as determined by a slit lamp examination, an evaluation of meibomian gland drop out with meibography, and a standard patient evaluation of eye dryness questionnaire of >5. Eligibility was then determined by a LLT of <75 nm at baseline and the inability to increase LLT ≥15 nm with three blinks, as determined by interferometric methods.

Characterization of dry eye disease in diabetic patients versus nondiabetic patients.

Purpose: The purpose of this investigation was to assess the presence and relative severity of dry eye evaluated by a panel of diagnostic methods in diabetic patients as compared with that in nondiabetic patients.

Methods: Patients (≥40 years of age) scheduled for a routine eye examination at the clinical site were recruited for the study. Exclusion criteria included current use of topical medication for glaucoma or prior ocular surgery if the patient was within the postoperative recovery period (3 months).

Optical quality and impact resistance comparisons of 2 football helmet faceshields.

Background: Currently there is no standard that specifically addresses the optical and impact performance of football protective faceshields. This study compared the impact resistance and optical quality between 2 popular football faceshields. Testing was performed only on new faceshields.
