OBJECTIVE Pituitary adenomas (PAs) are benign neoplasms that are frequently encountered during workup for endocrinopathy, headache, or visual loss. Transsphenoidal surgery remains the first-line approach for PA resection. The authors retrospectively assessed complication rates associated with transsphenoidal PA resection from an institutional database. METHODS A retrospective analysis of 1153 consecutive transsphenoidal pituitary adenoma resections performed at the Keck Hospital of USC between November 1992 and March 2017 was conducted...

OBJECTIVE Rathke's cleft cysts (RCCs) are benign epithelial lesions of the sellar region typically treated via a transsphenoidal approach with cyst fenestration and drainage. At present, there is limited evidence to guide patient selection for operative treatment. Furthermore, there is minimal literature describing factors contributing to cyst recurrence. METHODS The authors conducted a retrospective analysis of 109 consecutive cases of pathology-confirmed RCCs treated via a transsphenoidal approach at a single center from 1995 to 2016...

INTRODUCTION: As our population ages and comorbidities rise, ophthalmic surgeons are increasingly faced with patients on anticoagulant therapy or with clotting disorders. The ophthalmic surgeon has to weigh the perioperative risk of haemorrhage when anticoagulation continues against the risk of thromboembolism caused by discontinuation or changing the patient's medication (bridging, switching, cessation). There are currently no guidelines or recommendations. METHODS: A survey was sent to the DOG (German Ophthalmologic Society) divisions and associated surgical organizations to determine the status quo...

Vascular malformations (VMs) of the head and neck can lead to aesthetic problems as well as cranial nerve damage, airway compromise, and vision loss. Large VMs are typically managed surgically, with sclerotherapy or embolization performed in the perioperative period to decrease the risk of excessive blood loss and minimize the size of the VM. However, this initial treatment is frequently insufficient leading to excessive blood loss intraoperatively, poorer margin visualization for the surgeon, and decreased likelihood of complete resection...

OBJECTIVE: Our objective was to determine primary open-angle glaucoma (POAG) prevalence among obstructive sleep apnea (OSA) patients because the perioperative environment risks further damaging the optic nerve. STUDY DESIGN: We analyzed a "convenience sample" referred by Sleep Medicine for oral appliances because of continuous positive airway pressure intolerance. We determined the aggregate prevalence of the 3 POAG subtypes-"classic" open-angle glaucoma (COAG), normal-tension glaucoma (NTG), and open-angle glaucoma suspect (OAGS)-among the index population and compared it with that of same hospital's general population...

Perioperative vision loss (POVL) may cause devastating visual morbidity. A prompt anatomical and etiologic diagnosis is paramount to guide management and assess prognosis. Where possible, steps should be undertaken to minimize risk of POVL for vulnerable patients undergoing high-risk procedures. We review the specific risk factors, pathophysiology, and management and prevention strategies for various etiologies of POVL.

Transient vision loss after major surgical procedures is a rare clinical complication. The most common etiologies are cardiac, spinal, head, and neck surgeries. There has been no report on vision loss after lung resection. A 65-year-old man was admitted to our clinic with lung cancer. Resection was performed using right upper lobectomy with no complications. Cortical blindness developed 12 hours later in the postoperative period. Results from magnetic resonance imaging and diffusion-weighted investigations were normal...

Perioperative vision loss in non-ocular surgery represents a rare but devastating complication and multiple causes have been proposed. Any portion of the visual system may be involved and several authors have tried to relate that complication with deliberate hypotension anaesthetic technique, used to control intraoperative bleeding. We report a patient operated for orthognathism who suffered unilateral blindness. After review of similar cases, we can state that the transmission of forces generated during Le fort I osteotomy is related to the complication...

Perioperative dry eye syndrome (DES) is a common ocular complication of long-term general anesthesia. Chronic DES can lead to permanent damage to the cornea and disturbance of visual function, up to total loss of vision. Here, a relationship between the duration of general anesthesia and the risk of chronic DES in patients was demonstrated. Using an experimental model of perioperative corneal abrasions in rabbits, it was found that introduction of animals to 3-h general anesthesia resulted in clinically significant chronic damage to the cornea in 50% of cases...

BACKGROUND: Glaucoma is the international leading cause of irreversible blindness. Intraocular pressure (IOP) is the only currently known modifiable risk factor; it can be reduced by medications, incisional surgery, or laser trabeculoplasty (LTP). LTP reduces IOP by 25% to 30% from baseline, but early acute IOP elevation after LTP is a common adverse effect. Most of these IOP elevations are transient, but temporarily elevated IOP may cause further optic nerve damage, worsening of glaucoma requiring additional therapy, and permanent vision loss...

Perioperative vision loss is a rare complication of orthopaedic surgery and has been documented after spine, knee, hip, and shoulder procedures. It is associated with several ophthalmologic diagnoses, most commonly ischemic optic neuropathy. Although the pathophysiology remains unclear, current evidence suggests that systemic hemodynamic compromise and altered balance of intraocular perfusion contribute to the development of ischemic optic neuropathy. Although vision recovery has been reported, the prognosis of perioperative vision loss is poor, and no proven effective treatment is available...

BACKGROUND: Giant frontal mucoceles, characterized by significant intracranial and/or intraorbital extension, can present with significant neurologic symptoms. Although typical mucoceles are managed endoscopically, giant mucoceles are often treated with an open or combined approach due to various concerns, including frontal lobe displacement, size, and rapid decompression of the intracranial component. The impact of significant intracranial extension on outcomes is not well described...
