Objective: Orbital varix is a rare distensible orbital venous malformation. Most patients present with unilateral intermittent periorbital pain and positional proptosis that is exacerbated by the Valsalva maneuver. Complications include hemorrhage and thrombosis, leading to sudden painful proptosis and visual disturbance.

Case Description: We report on a 62-year-old woman with a history of poorly controlled hypertension who presented with sudden bilateral visual loss and headache for 5 days. She denied a history of head trauma.
Purpose: To report a case of endogenous panophthalmitis in a patient with COVID-19 during treatment in an Intensive Care Unit.
Observation: A 64-year-old woman with COVID-19 and septicemia presented with decreased visual acuity, ocular pain, and proptosis in her right eye after treatment with favipiravir, intravenous dexamethasone, and ceftriaxone. An ocular examination of her right eye revealed periorbital tenderness, exophthalmos, and corneal haze.
Purpose: To evaluate the functional and cosmetic outcomes, as well as factors that influence surgical success of maximal levator resection beyond Whitnall's ligament in patients with poor levator function (LF) and severe simple congenital ptosis.
Methods: This retrospective interventional study included patients with severe simple congenital ptosis and LF of ≤4 mm who had undergone maximal levator resection beyond Whitnall's ligament with a minimum of 12 months follow-up. Postoperative marginal reflex distance-1 (MRD1) was assessed for functional outcomes as excellent, good, fair and poor.
Background: Facial rejuvenation and reconstruction with autologous fat injection are a common and effective procedure used worldwide. Most surgeons and patients are satisfied with the favorable outcomes. However, catastrophic complications from arterial and venous occlusion resulting in visual loss and stroke may occur.

Diagnostic carotid artery angiography revealed an orbital lymphatic-venous malformation (LVM) concomitant with an intraorbital arteriovenous fistula. The patient was treated with transvenous coil and N-butyl cyanoacrylate glue embolization, combined with direct percutaneous glue injection into the LVM followed by excision.

Methods: In this retrospective, consecutive series, the medical records and photographs of 77 patients were reviewed.
Primitive neuroectodermal tumor of the orbit in adults: a case series.
Ophthalmic Plast Reconstr Surg
August 2011
Purpose: To present the clinical, radiologic, and histopathologic features of orbital primitive neuroectodermal tumor (PNET) in 5 adult patients.
Methods: Retrospective case series of 5 adult patients with orbital PNET. Orbitotomy was performed in all cases.
Purpose: To evaluate radiographic volume changes in extraocular muscles (EOM) following orbital decompression for thyroid-related orbitopathy (TRO).
Methods: Medical records of 22 orbits in 12 patients undergoing postoperative orbital CT after orbital decompression for TRO were retrospectively reviewed. All orbits demonstrated no signs of clinical reactivation of TRO.
