To determine if retrobulbar injection of hyaluronidase reaches the vitreous cavity, and to determine its concentration in the vitreous.

Prospective case-control study. Patients undergoing evisceration with implant for noninfective blind eyes were enrolled in the study. Before the evisceration, a retrobulbar injection of 3,000 IU of hyaluronidase (2 ml) was injected. Time from injection to in vivo sampling of posterior vitreous was noted. Vitreous samples from controls were obtained from patients undergoing vitrectomy for retinal detachment or diabetic retinopathy. Concentration of hyaluronidase was assessed in all 30 samples. An ELISA-based microtiter-technique was used to evaluate the activity of hyaluronidase by an avidin-peroxidase-based procedure using an ELISA reader. Incubations were carried out at room temperature and at 37°C. All the samples were analyzed in duplicates, and the mean of each sample was plotted on a scatter plot.

Total of 30 vitreous samples were analyzed, of which 15 were controls and 15 were test samples. Of the 15 test samples, injection-to-sampling time was 0 to 20 minutes in 4 samples, 20 to 40 minutes in 6 samples, and 40 to 60 minutes in 5 samples. The highest concentration of hyaluronidase detected in control and test samples were 2.9 and 3.0 µg/ml, and the lowest concentration was 1.7 and 1.5 µg/ml (SD 0.3), respectively. There was no significant difference between control and test groups.

Retrobulbar injection did not result in higher concentration of hyaluronidase in the posterior vitreous compared with controls when measured up to 60 minutes following injection.

This series reports 3 cases presenting with chronic conjunctivitis lasting an average of 10 years without cicatrix formation, ultimately diagnosed as OCP based on direct immunofluorescence of conjunctival biopsy samples. This chronic conjunctivitis without fibrosis suggests the possibility of an OCP subtype with a prolonged early stage or prodrome prior to cicatrization, which may benefit from early diagnosis and treatment to prevent complications of this disease.
To describe patients with periocular solitary extramedullary plasmacytoma (SEMP) and multiple myeloma (MM), together with an estimate of the risk of progression from SEMP to MM.

A retrospective case-note review for patients seen between 1978 and 2020, examining demographics, presentation, imaging, pathology, management, and outcome.

Twenty patients (10 male; 50%) presented at a mean age of 60.9 years, with an average symptom duration of 4.5 months. Ten (50%) patients had known systemic myeloma at ophthalmic presentation (the MM group) and, on average, they presented one decade earlier than those with occult MM discovered after orbital biopsy (p = 0.06); the majority (9/15; 60%) of patients with MM were female, whereas there was a male bias (4/5; 80%) with SEMP (p = 0.30). Most tumors (15/20; 75%) were within the anterior part of the orbit, especially superolaterally (16 patients; 80%), and the soft-tissue mass often appeared to "explode" from the frontal bone or greater wing of the sphenoid (16/20; 80%)nts with periocular plasmacytoma appear to have a SEMP at ophthalmic presentation, a half of these patients were found to have occult MM within 6 months of biopsy. Of those without systemic disease around the time of biopsy, none developed MM over an average follow up of more than 9 years.Iatrogenic needle penetrating ocular injuries are rare but can result in serious consequences. The authors report a case of inadvertent intraocular hyaluronic acid injection during esthetic periorbital facial enhancement. Visual field, visual evoked potential, and electroretinogram were used for monitoring potential side effects.
The aim of this study was to monitor blood perfusion in human upper eyelid skin flaps and examine how the perfusion is affected by the thickness of the flap.

Twenty upper eyelids were dissected as part of a blepharoplasty procedure in patients. The medial end of the blepharoplasty flap remained attached to mimic a flap design often used in reconstruction in the periocular area, a myocutaneous flap in which the blood supply follows the fibers of the orbicularis muscle and is thus parallel to the long axis of the flap. The muscle was thereafter dissected from the flap to create a cutaneous flap. Blood perfusion in the 2 types of flaps was compared using laser speckle contrast imaging.

Blood perfusion decreased gradually from the base to the tip of all the flaps. Perfusion was significantly higher in the myocutaneous flaps than in the cutaneous flaps (p < 0.0004) 69% in the myocutaneous flaps and 43% in the cutaneous flaps, measured 5 mm from the base. Blood perfusion was preserved to a greater extent distally in the myocutaneous flaps (minimum value seen at 25 mm) than in the cutaneous flaps (minimum seen at 11 mm).

Blood perfusion was better preserved in myocutaneous flaps, including both skin and the orbicularis oculi muscle, than in cutaneous flaps. This may be of clinical interest in patients with poor microcirculation in which a long flap is required for reconstructive surgery.

To describe the efficacy of tocilizumab in the treatment of a cohort of patients with active thyroid-associated orbitopathy.

Patients were identified with active thyroid-associated orbitopathy who were intolerant of or had progression of disease despite systemic corticosteroids and subsequently were treated with tocilizumab between January 2015 and December 2020. Clinical Activity Score, Thyroid-Associated Ophthalmopathy Scale score, and thyroid-stimulating immunoglobulin levels were assessed prior to initiation of tocilizumab, following the first dose, and after the completion of treatment.

Eleven patients were candidates for and underwent treatment with tocilizumab, 9 of which met criteria for analysis. Average age was 55.6 years. Average time between onset of active thyroid-associated orbitopathy and completion of tocilizumab was 6.5 months. Average number of infusions was 4.2. There was a statistically significant reduction in Clinical Activity Score, Thyroid-Associated Ophthalmopathy Scale score, aab as a therapy for the inflammatory phase of thyroid-associated orbitopathy.A 10-month-old girl presented with eyelid edema and erythema that did not improve with systemic antibiotics. Due to a lack of improvement, MRI was performed to avoid ionizing radiation from CT. An orbital abscess was recognized and drained. However, the abscess recurred 2 times. CT scan was performed and a tract in the sphenoid bone helped to diagnose a congenital dural sinus tract with dermoid. Definitive surgery was performed with neurosurgery to remove the entire tract including cutaneous connection. CT scan proved critical to diagnosis and should be considered in infants in select cases despite the concern for ionizing radiation in this vulnerable age group.
To explore the anatomy, etiopathogenesis, diagnosis and classification, current evidence on intervention and the surgical management of orbital roof fractures and defects (ORFD) for oculoplastic surgeons presented with such cases.

A review of the current literature through the MEDLINE database using the following search terms "orbital roof fracture (+treatment/management)," "orbital roof defect (+treatment/management)," "orbital roof erosion (+treatment/management)," "orbital roof repair," "orbital roof," "orbital fracture," "pediatric orbital roof (defect/fracture/erosion)," "orbital anatomy," and "orbital roof anatomy" was conducted. As relatively little has been published on this topic, inclusion criteria were broad and peer-reviewed articles judged to be of clinical importance, relevant to the aims of this review, were included. Non-English abstracts were also included if relevant. Year of publication was not a strict exclusion criterion, and older articles were judged for their suitability based on clinical importance and relevance to current practice. Additional references were obtained from citations in key articles and recommendations from the coauthors based on their areas of expertise.

The etiopathogenesis of ORFD varies. Classification systems have been formulated to guide management decisions and can range from conservative management to complex neurosurgery. Eyelid approaches have also been described. This review provides a summary of the evidence for each and a management framework oculoplastic surgeons can use when presented with ORFD.

Oculoplastic surgeons can be involved, either alone or as part of a multidisciplinary team, in the management of ORFD, and for some, conduct orbital approach reconstructive surgery.

Despite increasing numbers of women oculoplastic surgeons, they remain underrepresented within the subspecialty. The purpose of this study was to analyze trends in gender authorship within the field of ophthalmic plastic and reconstructive surgery.

This retrospective observational study sampled articles published in Ophthalmic Plastic and Reconstructive Surgery (OPRS) and Orbit during the years 1985, 1995, 2005, 2015, and 2020. Data reviewed included article type, total number of authors, and the gender of each article's first and senior author.

Nine hundred ninety-nine articles were analyzed, including 701 in OPRS and 298 in Orbit. Of 3,716 total authors, 1,151 (31%) were women, including 297 (29.7%) first authors, and 191 (21.5%) senior authors. Women authorship in OPRS in 1985 (first, 3.9%; senior, 3.3%; all, 3.2%) significantly increased by 2020 (first, 44.6%; senior, 27.9%; all, 42%). Women authorship in Orbit in 1985 (first, 0%; senior, 4.5%; all, 7.4%) also significantly increased by 2020 (first, 43.
