INTRODUCTION: With a rapidly expanding elderly population in the United States, the incidence of pituitary adenomas in elderly will continue to rise. In this study, we aim to evaluate the safety and efficacy of transsphenoidal endoscopic endonasal resection for pituitary adenomas in the elderly population. METHODS: A retrospective review was performed of 131 consecutive patients who underwent transsphenoidal endoscopic endonasal resection for pituitary adenomas at the University of Miami Hospital between 2012 and 2016...

BACKGROUND: Symptoms that mimic pituitary apoplexy may be encountered with other neoplastic or infectious lesions. CASE DESCRIPTION: This 38-year-old man presented with severe sudden-onset headache and relapsing and remitting vision loss. Radiographic imaging studies demonstrated radiographic features of a hyperdense, hemorrhagic mass in the sellar region. MRI revealed a 4-cm mass abutting the optic chiasm and compressing the pituitary. After 4-week follow-up surveillance MRI demonstrated near-complete resolution of the previously identified planum sphenoidale and suprasellar mass, the patient re-presented 13 months later with recurrent symptoms...

BACKGROUND/OBJECTIVE: This study aimed to investigate the visual performance of a new extended depth-of-focus intraocular lens (EDOF-IOL). SUBJECTS/METHODS: In this multicenter, prospective, observational study, we enrolled 97 patients who underwent cataract surgery or refractive lens exchange with implantation of the Mini Well EDOF-IOL (SIFI, Italy). Patients underwent postoperatively the following examinations between 4 and 8 weeks after surgery: corrected distance visual acuity (CDVA), reading speed with Radner's chart, distance-corrected near visual acuity (DCNVA), defocus curve, contrast sensitivity, and haloes quantitative assessment...

INTRODUCTION: Treatment of AVMs is, nowadays, performed at specialized neurosurgical centers, which are well equipped with microscope with green filter, neurosurgical cath-lab and experienced neurosurgeons team. The patients diagnosed with AVMs at smaller hospitals should be referred to such hospitals. But what happens when a neurosurgeon has to face the unavoidable worst case scenario, i.e., emergency unplanned surgical excision of undiagnosed, ruptured AVM with large hematoma. This case report is about management of such case...

OBJECTIVE: Although meningiomas frequently involve the optic nerve, primary optic nerve sheath meningiomas (ONSMs) are rare, accounting for only 1% of all meningiomas. Given the high risk of vision loss with these tumors, surgical intervention is seldom considered, and radiation or observation is commonly applied. Here, the authors describe the visual outcomes for a series of patients who were treated with surgery aiming at maximal tumor resection and highlight their prognostic factors...

OBJECTIVE: The unexpected intraoperative intraventricular hemorrhage is a rare but feared and life-threatening complication in neuroendoscopic procedures because of loss of endoscopic vision. The authors present their experience with the so-called "dry field technique" (DFT) for the management of intraventricular hemorrhages during purely endoscopic procedures. This technique requires the aspiration of the entire intraventricular CSF to achieve clear visualization of the bleeding source...

PURPOSE: To evaluate the effect of riboflavin-ultraviolet (UV)-A corneal crosslinking (CXL) without epithelial removal on ectatic corneal disease. SETTING: Woolfson Eye Institute, Atlanta, Georgia, USA. DESIGN: Prospective observational study. METHODS: Patients were treated with a new riboflavin formulation without epithelial removal, then exposed to UV light (365 nm) at 4 mW/cm2 with on-off cycling for 30 minutes...

RATIONALE: Being required to perform neurosurgery on a pregnant woman is rare, but occasionally unavoidable. In these cases, clinical anesthesiologists are confronted with conflicting information and few evidence-based guidelines. PATIENT CONCERNS: Here, we describe the successful anesthetic management of a 24-week pregnant woman with macroprolactinoma who underwent endonasal transsphenoidal resection of pituitary adenoma. DIAGNOSES: According to the prolactin (PRL) level and magnetic resonance imaging (MRI) results, the patient was diagnosed with macroprolactinoma and kept stable after taking the regular bromocriptine treatment...

Intracranial meningiomas such as olfactory groove meningioma (OGM) and tuberculum sellae meningioma (TSM) arising at the anterior skull base are amenable to surgical resection. Traditionally, this has been achieved by transcranial approaches (TCAs), however, there has been an evolution in an endoscopic endonasal approach (EEA) within recent years. The aim of this systematic review and meta-analysis was to determine if the EEA was superior to the TCA in managing these anterior skull base meningioma based on comparative studies only, and highlight the limitations of the current literature...

This study was aimed to assess the clinical outcomes of Visian ICL (hole ICL; STAAR Surgical, Inc.) implantation for the correction of myopic refractive errors in eyes having an anterior chamber depth (ACD) below the current manufacturer's recommendation (<3.0 mm). We comprised 365 eyes of 201 consecutive patients (mean age ± standard deviation, 35.7 ± 7.5 years) with spherical equivalents of -8.66 ± 3.54 D. We evaluated the safety, efficacy, predictability, stability, intraocular pressure (IOP), endothelial cell density (ECD), and complications...

AIM: To compare intraoperative phacoemulsification parameters and its effect on the corneal endothelium of eyes undergoing femtosecond laser-assisted cataract surgery (FLACS) versus conventional phacoemulsification (CP) cataract surgery. METHODS: Two hundred eyes from one hundred patients were included in a prospective, non-blinded, randomized, controlled, intraindividual clinical study. One hundred eyes underwent FLACS while their one hundred fellow eyes underwent CP...

An elderly male with monocular status presented with complaints of gradual loss of vision in his left eye. Slit-lamp evaluation revealed postradial keratotomy (RK) corneal decompensation. He underwent non-Descemet stripping automated endothelial keratoplasty (nDSAEK) in his left eye. Postoperatively, his visual acuity improved from counting finger at 1 m to 20/200, J5. Graft adherence was good. A preexisting epiretinal membrane with macular edema was noted, but our patient refused any further surgical intervention for the same...

INTRODUCTION: Acute dacryocystitis usually presents as a pre-septal cellulitis since the lacrimal sac lies anterior to the orbital septum. Orbital cellulitis secondary to acute dacryocystitis is very rare due to a variety of anatomic barriers to the orbit but can occur and result in abscess formation with risk of visual compromise. PRESENTATION OF CASE: We describe a case of otherwise healthy adult who presented with complete visual loss following orbital cellulitis and abscess formation secondary to acute dacryocystitis...

BACKGROUND/AIMS: The main aim of this study was to evaluate the safety and efficacy of diode laser transscleral cyclophotocoagulation (TSCPC) in eyes with good visual acuity. PATIENTS AND METHODS: A retrospective chart review identified patients who underwent TSCPC for uncontrolled intraocular pressure (IOP) from 2014 to 2016. Enrollment criteria included pretreatment best-corrected visual acuity (BCVA) of 20 of 40 or better, and a minimum of 6 months of postoperative follow-up...
