PURPOSE: To review the clinical and histopathologic findings associated with subepidermal calcinosis of the eyelids. METHODS: A systematic review of the literature on subepidermal calcinosis of the eyelids was performed. Cases included were idiopathic in nature and met the histologic criteria for subepidermal calcinosis with calcium deposits in the dermis of the skin. RESULTS: Twenty-one publications presenting 53 cases of subepidermal calcinosis involving the eyelids were published between 1970 and 2016...

Md Shahid Alam, D Vaidehi, K Lily Therese, Mohammad Javed Ali
Transient nasolacrimal duct obstruction secondary to a mass lesion compressing the sac or sac-duct junction is rare. We report a case of a young female who presented to us with complaints of watering and a mass lesion in the lacrimal sac region. An organized perilacrimal mass filled with thick pultaceous material was noted during surgery. Following the drainage of the mass lesion, irrigation of the lacrimal system was freely patent. Microbiological examination and DNA sequencing targeting interspacer region was suggestive of Pleurostomophora richardsiae species...

PURPOSE: To review the outcomes of patients with optic nerve sheath meningiomas (ONSM) treated with fractionated stereotactic radiotherapy. METHODS: Patient characteristics, treatment, and outcomes were analyzed for all patients with primary and secondary ONSM treated from 2001 to 2012. Clinically significant visual acuity change was defined as a 2-line change on the Snellen eye chart from pre-fractionated stereotactic radiotherapy. RESULTS: Forty-one patients were treated: 23 patients with primary ONSM and 18 patients with secondary ONSM...

#4
Sima Das, Mohammad Javed Ali, Smriti Bansal, Manpreet Chugh, Nishi Gupta, Vidya Janaki
Pneumatocele of the lacrimal sac is an uncommon entity and has been rarely reported in literature. The valvular function of the Hasner's valve at the lower end of nasolacrimal duct is presumed to prevent the retrograde reflux of air into the lacrimal sac with increased intranasal pressure as in valsalva maneuver. Loss of this valvular function as noted with persistent positive airway pressure ventilation can cause retrograde air reflux into lacrimal sac. The authors report a case of lacrimal sac pneumatocele which developed following blunt nasal trauma involving the bony nasolacrimal duct...

#6
Ivan Vrcek, Eva Chou, Marie Somogyi, John W Shore
PURPOSE: Loss of volume in the sub-brow fat pad with associated descent of the eyebrow is a common anatomical finding resulting in both functional and aesthetic consequences. A variety of techniques have been described to address brow position at the time of blepharoplasty. To our knowledge, none of these techniques treat the sub-brow fat pad as an isolated unit. Doing so enables the surgeon to stabilize and volumize the brow without resultant tension on the blepharoplasty wound. The authors describe a technique for addressing volume loss in the eyebrow with associated brow descent that treats the sub-brow fat pad as an isolated unit...

PURPOSE: Recent publications have reported the adverse effects of prostaglandin analogues on the periocular tissues. These medications may cause periorbital lipodystrophy, enophthalmos, and deepening of the superior sulcus deformity. While these effects may have adverse consequences for some patients, the atrophy of the periorbital fat may have a useful role in diseases that lead to orbital and periorbital fat hypertrophy such as thyroid eye disease. In this pilot study, the authors investigated the effects of retrobulbar bimatoprost injection on the intraocular pressure and orbital fat in a rat animal model...

Yue Zhao, Rao V Chundury, Alexander D Blandford, Julian D Perry
PURPOSE: The zygomaticofacial/temporal/orbital nerve is a terminal branch of the zygomatic nerve and exits the orbit through zygomatic foramina. The nomenclature in the literature varies with some studies identifying all 3 foramina on the malar surface of the zygoma, while others describe each along different aspects of the zygoma. In this study, foramen on the malar surface of the zygoma is termed zygomatic foramen, and the authors describe anatomical variations in the position and number of these foramina in an African American population...

Arpine Barsegian, Adam Botwinick, Harsha S Reddy
PURPOSE: To characterize the phenylephrine test in ptotic patients to help clinicians perform the test more efficiently. METHODS: Adults with involutional ptosis (n = 24, 30 eyes) were assessed with digital photographs for response to topical 2.5% phenylephrine drop instillation. Patient characteristics (age, gender, iris color, dermatochalasis, brow ptosis, and baseline marginal reflex distance-1 [MRD-1] height) were recorded. From the photographs, change in (MRD-1), presence of conjunctival blanching, pupillary dilation, and Hering effect were recorded at specified time intervals, 1 minute to 1 hour after drop placement...

PURPOSE: The programmed death-1 pathway negatively regulates the immune system. Previous reports have indicated worse tumor-related outcomes with increased expression of the ligand for this pathway. This study was undertaken to assess the role of the PD pathway in cutaneous malignancies that invade the orbit. METHODS: Immunohistochemical staining for the programmed death-1 receptor and ligand was performed on exenteration specimens of invasive cutaneous orbital malignancies (n = 12) and nodular basal cell carcinoma (n = 10)...

Primary orbital natural killer T-cell lymphoma (NKTCL) is a rare condition with only a few published cases in the literature. Over 1 month, an 81-year-old man developed progressive left periocular inflammation unresponsive to treatment. Clinical examination and imaging studies demonstrated a left lacrimal gland enlargement. Bilateral anterior uveitis and erythematous nontender cutaneous lesions were also found. Biopsies of the skin and lacrimal gland on the back revealed histopathologic and immunohistochemical findings confirming Epstein-Barr virus-positive NKTCL...
