Purpose: To determine the prevalence, clinical features, and radiographic findings of superior ophthalmic vein periphlebitis (SOVP) in thyroid eye disease (TED).

Methods: Patients with a clinical diagnosis of thyroid eye disease and contrast-enhanced imaging were included. Imaging was reviewed for the presence of SOVP, and patients with SOVP were compared to those without.

Hemorrhage Following Muller's Muscle Conjunctival Resection: Description and Case-Control Study.

Purpose: The purpose of this study was to report a series of patients with postoperative hemorrhage after Muller's muscle conjunctival resection surgery and compare risk factors and outcomes with a control population.

Methods: In this case-control study, records of patients who underwent Muller's muscle conjunctival resection over 5 years were reviewed for a history of postoperative hemorrhage occurring >24 hours after surgery. A 4:1 control population was matched for age and sex.

Radiologic Features of Well-circumscribed Orbital Tumors With Histopathologic Correlation: A Multi-center Study.

Purpose: To delineate specific imaging characteristics of solitary fibrous tumors, schwannomas, cavernous venous malformations, and well-circumscribed orbital lymphoma.

Methods: Patients undergoing excisional biopsy of solitary fibrous tumor, schwannomas, cavernous venous malformations, or well-circumscribed orbital lymphoma with preoperative MRIs available for review were identified at 3 academic centers in the United States and Australia. An exploratory statistical analysis was performed to identify important radiologic features, which were subsequently included in a random forest model.

Inferior Oblique Flap: An Approach for Improved Vascular Supply in Complex Ocular Surface Reconstruction.

This case report describes a novel surgical technique using an inferior oblique muscle flap for a patient requiring complex ocular surface reconstruction. A 63-year-old female with Stevens-Johnson syndrome and complex ocular history including multiple penetrating keratoplasties and keratoprostheses presented with recurrent keratoprosthesis implant plate necrosis. In conjunction with revision keratoplasty, a custom inferior oblique muscle flap was designed to provide improved support and vascularity to the corneal tissue bed; at 12 months postoperation, the graft remained well attached and free of graft failure.

Comparison of long-term outcomes of simultaneous accelerated corneal crosslinking combined with intracorneal ring segment or topography-guided PRK.

Transorbital Endoscopic Approach to the Pterygopalatine Fossa: A Less Invasive Alternative to Traditional Access.

Purpose: The purpose of this article and accompanying video is to demonstrate a transorbital endoscopic approach for accessing the pterygopalatine fossa (PPF). This technique does not require a skin incision, avoids dissection of critical neurovascular structures, and utilizes a comparatively small osteotomy. The 2 cases presented in this article highlight the utility of a transorbital endoscopic approach for accessing an anatomic region that has traditionally required more invasive techniques to reach.
