Purpose: Retrobulbar hematoma is an uncommon but potentially devastating complication following repair of orbital fractures. Since 2007, the senior author routinely fenestrates the solid porous polyethylene implants commonly used for orbital reconstruction. The perforated implant may facilitate drainage of postoperative bleeding and may potentially reduce the risk of retrobulbar hematoma. This study examines the rates of retrobulbar hematoma in patients who underwent orbital fracture reconstruction with placement of fenestrated or nonfenestrated implants.
Methods: A retrospective chart review of patients with orbital fracture reconstruction using an implant performed by the senior author between 2006 and 2016 was conducted. Data collected included age, sex, implant type, and presence of retrobulbar hematoma.
Results: One hundred four patients were included in the study. One patient who was treated with a nonperforated implant was found to have a postoperative retrobulbar hematoma. The retrobulbar hematoma did not cause visual changes or increased intraocular pressure, so the patient was observed and did not undergo any surgical intervention. The hematoma resolved spontaneously without further sequela. No patients with fenestrated implants had a retrobulbar hematoma.
Conclusions: Fenestration of solid implants used in orbital floor reconstruction is simple and easy to perform, and may reduce the incidence of postoperative retrobulbar hematoma.

Retrobulbar hematoma (RH) is a diagnostic and therapeutic emergency that may cause permanent vision loss. Lateral canthotomy and cantholysis (LCC) is typically performed when IOP is elevated or vision is compromised. The authors describe the outcomes of the largest cohort of patients with RH to date.

Introduction: Maxillofacial injuries are usually associated with ophthalmic injuries that may be mild to severe, and may even result in loss of integrity of the orbital skeleton and impairment of the visual apparatus.
Aim: To evaluate the pattern of ophthalmic injuries associated with maxillofacial fractures in patients who reported to a tertiary care hospital, associated with a medical college in M.P, India.

Background: Malignant dysgerminomas are infrequently reported ovarian neoplasms in animals, especially in exotic pets (non-traditional companion animals [NTCAs]). In the few published case reports on reptilian species, examples are primarily postmortem without antemortem (clinical) assessment.
Patient Presentation: An adult, 13-year-old, spayed female inland bearded dragon (Pogona vitticeps) presented with lethargy, a right-sided head tilt, unilateral exophthalmos and ventrotemporal strabismus on the right eye.

Background: Traumatic optic neuropathy (TON) is a rare complication of facial trauma that results in vision loss. Clinical diagnosis of TON is based on a history of head trauma and an ophthalmic examination; however, the risk factors for TON and the ideal treatment strategy remain undetermined. This study aimed to identify predictive risk factors for TON and evaluate the effectiveness of current treatments with respect to visual outcomes in patients with TON.
