Frozen Section Histoanatomy of the Peritarsal Eyelid.

Background: Mohs surgery of eyelid skin cancers requires detailed knowledge of anatomy for precise surgery and accurate evaluation of histology.

Objective: To review the histology of the peritarsal eyelid using frozen sections as encountered intraoperatively by Mohs surgeons.

Methods: The authors review the literature describing the anatomy and histology of the peritarsal eyelid from the lens of a Mohs surgeon.

Cavernous sinus thrombosis with bilateral orbital vein involvement and diffuse ischemic retinopathy.

A 53-year-old man with a 3-day history of periorbital swelling and vision loss in the left eye was found to have septic cavernous sinus thrombosis with bilateral orbital vein involvement causing congestive orbitopathy. He was treated with an emergent canthotomy and cantholysis, intraocular pressure-lowering drops, antibiotics, anticoagulation, and serial examinations. Optical coherence tomography ultimately revealed diffuse ischemic destruction of both layers of the retina, which suggested occlusion of the ophthalmic artery or the short posterior ciliary arteries and central retinal artery without intracavernous internal carotid artery involvement.

Seven-Year Follow-Up of a Patient With a Retained Needlefish Jaw Fragment Abutting Against His Left Internal Carotid Artery.

A 51-year-old man presented to the ophthalmology service with binocular diplopia and facial numbness. The patient was returning from a trip to Mexico. He reported having been hit in the left periocular region by a fish while swimming.

Regression of Sebaceous Carcinoma of the Eyelid after a Small Incisional Biopsy: Report of Two Cases.

Purpose: To report 2 cases of regression of sebaceous carcinoma of the eyelid after a small incisional biopsy.

Methods: Clinical, imaging, and histopathological findings are presented, with a literature review on regressing ocular tumors.

Results: Our first patient was a 79-year-old man who presented with a 10-month history of progressive left upper eyelid ptosis caused by an eyelid tumor with orbital involvement and confirmed on magnetic resonance imaging.

Is gastroesophageal reflux disease associated with primary acquired nasolacrimal duct obstruction?

Purpose: To determine if patients with primary acquired nasolacrimal duct obstruction (PANDO) have an increased prevalence of gastroesophageal reflux disease (GERD) compared to the general population.

Methods: Cross-sectional case-control study. The Mayo Clinic Reflux Disease Questionnaire (RDQ) is used to help physicians diagnose GERD.

Orbital ultrasonography in the diagnosis of neoplastic extraocular muscle enlargement.

Neoplastic infiltration of the extraocular muscle (EOM) is a rare condition which can pose a diagnostic dilemma due to its rarity and overlapping ultrasonographic features with orbital myositis. The ultrasonographic features of neoplastic enlargement of EOM have not been systematically studied and previously have been described in only a few case reports. Orbital ultrasonography, in conjunction with the pattern of ocular misalignment, was assessed for its potential role in identifying patients with neoplastic EOM enlargement.

Two- versus four-handed techniques for endonasal resection of orbital apex tumors.

Background: Open versus endonasal resection of orbital apex (OA) tumors is generally based on tumor size, location, and pathology. For endonasal resection, two- and four-handed techniques have been reported, but whether one technique is more optimal based on these tumor features has not been evaluated.

Objective: To determine whether two- versus four-handed techniques result in better outcomes after endoscopic resection of OA tumors, and whether either technique is better suited for intra- versus extraconal location and for benign versus malignant pathology.

Oculoplastic surgery.

Esthetic and functional surgery in the periocular region falls into the domain of oculoplastic surgeons, as well as plastic surgeons and otorhinolaryngologists with training in facial plastic surgery. This article provides a description of 8 common eyelid procedures that are routinely performed under local anesthesia, with or without mild intravenous sedation. Serious complications are rare.

Complications of blepharoplasty: prevention and management.

Blepharoplasty is an operation to modify the contour and configuration of the eyelids in order to restore a more youthful appearance. The surgery involves removing redundant skin, fat, and muscle. In addition, supporting structures such as canthal tendons are tightened.

Metastasis of uveal melanoma millimeter-by-millimeter in 8033 consecutive eyes.

Objective: To determine the rate of metastasis of uveal melanoma on the basis of tumor thickness in millimeters.

Methods: Retrospective medical record review.

Results: The mean (median) patient age was 58 (59) years.

Optical coherence tomography of choroidal osteoma in 22 cases: evidence for photoreceptor atrophy over the decalcified portion of the tumor.

Purpose: To evaluate the retinal status overlying choroidal osteoma using optical coherence tomography (OCT).

Design: Retrospective noncomparative case series.

Participants: Twenty-two eyes with choroidal osteoma.
