Predictability of Optic Foramen Location From a Ray Through the Ethmoidal Foramina.

Purpose: To determine how accurately a ray through the anterior and posterior ethmoidal foramina predicts the location of the optic foramen.

Methods: Dried, well-preserved, complete human skulls without bony defects belonging to the Hamann-Todd osteological collection of the Cleveland Museum of Natural History were examined. Photography was performed and a ray was drawn on orbit photographs extending through the center of the anterior and posterior ethmoidal foramina toward the optic canal.

Rotational Flap Repair of Full Thickness Eyelid Defects without a Posterior Lamellar Graft or Flap.

Background: To determine the safety and effectiveness of full thickness eyelid reconstructions using a semicircular rotational flap without reconstructing the posterior lamella.

Methods: The charts of all patients undergoing semicircular flap closure of full thickness eyelid defects by one surgeon (JDP) at the Cole Eye Institute between March 2000 and October 2012 were reviewed. Charts were reviewed for patient demographic information, as well as for the size of the defect, the type of flap used, length of follow-up and complications.

Medial orbital wall landmarks in three different North American populations.

Purpose: We sought to measure the medial orbital wall foramina distances in two previously unstudied populations, to describe a new bony medial wall feature, and to validate the accuracy of a new coordinate measurement device within the orbit.

Methods: Dried, well-preserved, complete human skulls without orbital defects were studied. Age, gender, birthplace, ethnicity, and laterality of the orbit were recorded for each skull.

Orbital xanthogranuloma in an adult patient with xanthelasma palpebrarum and hypercholesterolemia.

A 44-year-old man with a history of hypercholesterolemia presented with eyelid lesions and a separate orbital mass. Pathology of eyelid lesions confirmed xanthelasma palpebrarum, and pathology of the orbital mass showed a non-Langerhans cell xanthogranuloma, consistent with a lesion within the spectrum of adult orbital xanthogranulomatous disorders. While xanthelasma palpebrarum is associated with increased serum lipids, adult orbital xanthogranuloma does not share a clear association.

Internal cantholysis for repair of moderate and large full-thickness eyelid defects.

Purpose: To determine the safety and efficacy of internal cantholysis for closure of larger full-thickness eyelid defects.

Design: Retrospective review of a consecutive case series.

Participants: Eighteen patients (18 eyelids) underwent internal cantholysis for repair of a moderate or large full-thickness eyelid defect during the study period.

Conjunctival bleeding after ectropion repair due to paraneoplastic primary fibrinolysis.

In addition to predisposing a patient to hypercoaguability and thrombosis, cancers may also cause an antithetical bleeding diathesis through primary fibrinolysis. This paraneoplastic pathology has been documented and studied in prostate cancer patients for nearly a century but is under-recognized as a possible complication of surgery. We report a case of primary fibrinolysis after elective ectropion repair in a patient with prostate cancer.

Internal cantholysis for full thickness eyelid defects.

Eyelid reconstruction requires an understanding of normal eyelid anatomy and function. A thorough understanding of the basic anatomy, contour, and mobility of the eyelids is essential in restoring the tissue to its presurgical level. There are many different surgical options to assist in the repair of full thickness eyelid defects involving the margin.
