INTRODUCTION: Meningiomas with orbital extension are the most frequent benign orbital tumors. The few studies available on the postoperative complications of their excision focus on the postoperative evolution of proptosis, visual acuity and visual field deficits. The goal of our study was to highlight the oculoplastic complications secondary to their excision. MATERIAL AND METHOD: We identified all cases of meningiomas with orbital extension undergoing excision either neurosurgically or via an orbital approach in the ophthalmology and neurosurgery departments of Pasteur university medical center in Nice between February 2011 and January 2017...

PURPOSE: This study evaluates the reliability of a frequently used subjective measurement of orbital compliance (0-3 scale) and describes a simple, quantitative measure with excellent intra- and interrater reliability. METHODS: Two examiners performed both measurements on 100 orbits (50 consecutive patients) from the office of 1 oculoplastics surgeon. Each measurement was obtained at 2 different time points, 10 minutes apart. For the subjective measurement, the patient was asked to close their eyes, and the globe was displaced posteriorly with digital pressure until moderate resistance was felt...

With the rapid growth of the stem cell biology field, the prospect of regenerative medicine across multiple tissue types comes closer to reality. Several groundbreaking steps paved the way for applying stem cell biology to the several subfields within ophthalmology and oculoplastic surgery. These steps include the use of stem cell transplants as well as studies of various ophthalmologic pathologies at the molecular level. The necessity of stem cell transplant is readily apparent, having already been used for several studies such as artificial lacrimal gland design and eyelid reconstruction...

Importance: Although a variety of well-characterized diseases, such as sarcoidosis and granulomatosis with polyangiitis, affect the lacrimal gland, many patients with dacryoadenitis are diagnosed as having nonspecific orbital inflammation (NSOI) on the basis of histology and systemic disease evaluation. The ability to further classify the disease in these patients should facilitate selection of effective therapies. Objective: To test the a priori hypothesis that gene expression profiles would complement clinical and histopathologic evaluations in identifying well-characterized diseases and in subdividing NSOI into clinically relevant groups...

Accidental removal of the lacrimal gland is a rare complication of ptosis surgery. We report two children who underwent large unilateral levator palpebrae superioris resections (LPSr). After surgery, both patients developed dry eye. Post-operatively, the parents of both patients noticed no tears in the affected eye when their child cried. Computed tomography proved the absence of the lacrimal gland in the operated eye in both patients. Oculoplastic surgeons should pay close attention to the anatomy of the levator muscle and its proximity to surrounding tissues in order to avoid lesions on important orbital structures, including the lacrimal gland, and to avoid the development of long-term dry eye...

The management of blind, painful eyes in Sturge-Weber syndrome patients poses unique challenges to the oculoplastic surgeon. Intraocular and orbital vascular malformations and calcification may theoretically lead to unexpected hemorrhage and difficulty placing an implant in a calcified scleral shell. We present two cases of patients with Sturge-Weber syndrome with blind, painful eyes who underwent evisceration with silicone implant and discuss the relevant current literature. Both of our patients had uncomplicated surgeries and post-operative courses...

INTRODUCTION: Orbital decompression is the indicated procedure for addressing exophthalmos and compressive optic neuropathy in thyroid eye disease. There are an abundance of techniques for removal of orbital bone, fat, or a combination published in the scientific literature. The relative efficacy and complications of these interventions in relation to the specific indications remain as yet undocumented. We performed a systematic review of the current published evidence for the effectiveness of orbital decompression, possible complications, and impact on quality of life...
