Orbital Abscess Secondary to Nasolacrimal Duct Obstruction in an Extremely Preterm Infant.

Orbital abscesses are rarely encountered in children younger than 1 year. The literature is limited to isolated case reports and a few case series. Most such cases are reported in infants born at term, with the earliest reported gestational birth age at 34 weeks.

The Platysma Contraction Pattern in Healthy Adults: A Vector Analysis Study.

Background: The platysma muscle's role in lower face dynamics is complex. Multiple insertion points to soft-tissue structures at various levels in the lower face create a multifaceted contraction pattern. To avoid adverse effects in cosmetic procedures when targeting the platysma, its anatomy and physiology must be understood.

Does the histopathological subtype of primary basal cell carcinoma predict the subtype of secondary tumours? What role do genetic mutations play?

Background: Basal cell carcinoma (BCC) is one of the most common malignancies in the world. The frequency of histopathological subtypes and the distribution on the body of BCC has been well documented. Less has been written on the nature of secondary tumours.

Orbital metastasis of myxofibrosarcoma.

Myxofibrosarcoma (MFS), a common sarcoma in adults, typically affects the extremities. Primary orbital involvement is uncommon, and orbital metastasis is exceedingly rare. We describe a case of orbital MFS due to metastasis and provide an updated literature review.

Use of Porcine Urinary Bladder Matrix in Socket Reconstruction After Pediatric Orbital Exenteration.

Reconstruction options after orbital exenteration can be challenging, time-consuming, and require intensive postoperative care. Engineered dermal acellular matrices offer a quick and easy option for wound healing that has proven to be successful in various settings. Specifically, the porcine urinary bladder matrix has demonstrated success in periocular and orbital wound healing.

Lateral Tarsal Strip Complications With and Without Conjunctiva Stripping.

Purpose: The lateral tarsal strip (LTS) procedure is commonly used to correct eyelid malposition. When performing LTS, some surgeons elect to remove conjunctiva from the tarsal strip, while others do not. It has been hypothesized that without conjunctival stripping, the buried conjunctival tissue can cause complications such as inclusion cysts and granulomas.

Retinal Lineage Therapeutic Specific Effect of Human Orbital and Abdominal Adipose-Derived Mesenchymal Stem Cells.

Retinal degenerative diseases are one of the main causes of complete blindness in aged population. In this study, we compared the therapeutic potential for retinal degeneration of human mesenchymal stem cells derived from abdominal subcutaneous fat (ABASCs) or from orbital fat (OASCs) due to their accessibility and mutual embryonic origin with retinal tissue, respectively. OASCs were found to protect RPE cells from cell death and were demonstrated to increase early RPE precursor markers, while ABASCs showed a raise in retinal precursor marker expression.

Ocular Related Sports Injuries.

Ocular injuries occur frequently in sports, affecting the globe, surrounding soft tissues, and the orbital bony structure. This review provides the craniofacial surgeon a broad general overview of epidemiology, mechanism of disease, and prevention.

Local Anesthesia Injection in Upper Blepharoplasty Surgery: A Side at a Time or Both Sides at Once? A Prospective Randomized Study.

Background: Perceived pain during local anesthesia injections can be effected by the injection sequence.

Objective: We sought to compare pain levels during local anesthesia injections during upper lid blepharoplasty (ULB) using 2 surgical sequences.

Materials And Methods: We conducted a prospective, randomized clinical trial.

Outcomes of simultaneous photorefractive keratectomy and collagen crosslinking.

Objective: To report the outcomes and complications of combined photorefractive keratectomy (PRK) and collagen crosslinking (CXL).

Design: A retrospective cohort study of consecutive patients undergoing combined PRK-CXL between 2011 and 2013 at Care Laser, Inc, Tel Aviv, Israel.

Participants: Ninety-eight eyes of 56 patients were included.

Comparison of intraocular pressure measurements using Goldmann tonometer, I-care pro, Tonopen XL, and Schiotz tonometer in patients after Descemet stripping endothelial keratoplasty.

Purpose: Post-Descemet stripping endothelial keratoplasty (DSEK) patients are prone for intraocular pressure (IOP) elevations and glaucoma. Corneal characteristics influence various IOP measuring devices in various ways. The aim of this study was to evaluate the agreement between four different IOP measuring devices: Goldmann applanation tonometer (GAT), I-care pro, Tonopen XL, and Schiotz tonometr in patients who underwent DSEK.

FIVE-YEAR FOLLOW-UP AFTER EPIRETINAL MEMBRANE SURGERY: A Single-Center Experience.

Purpose: To evaluate the rate of epiretinal membrane (ERM) recurrence in eyes that underwent ERM peeling surgery at least 5 years earlier.

Methods: Retrospective interventional case series study of 37 patients (15 women and 22 men; mean age, 70 ± 7.6 years) operated on for ERM removal with a follow-up of at least 5 years.

INTERNAL ASPIRATION UNDER PERFLUOROCARBON LIQUID FOR THE MANAGEMENT OF LARGE MACULAR HOLES.

Purpose: To report the outcomes of pars plana vitrectomy with internal aspiration under perfluorocarbon liquid for large macular holes (MH).

Methods: Retrospective consecutive case series of patients with large (>400 µm) MH. All treated were with pars plana vitrectomy, internal limiting membrane peeling, internal fluid aspiration under perfluorocarbon liquid, and gas/oil tamponade.

Comparison of Ishihara Booklet with Color Vision Smartphone Applications.

Purpose: To compare the standard Ishihara booklet with color-vision-testing smartphone applications.

Methods: A prospective observational diagnostic study on 42 normal trichromats and 38 color-deficient subjects. Patients were presented with three color vision tests in random order: an Ishihara test booklet and two color-vision-testing smartphone applications: Eye2Phone and the Color Vision Test application (CVT app).

Early loss of monocanalicular silicone tubes in congenital nasolacrimal duct obstruction: incidence, predictors, and effect on outcome.

Purpose: To study predictors and implications on outcome of premature silicone tube-loss, a post-operative complication of monocanalicular intubation (MCI) performed for treatment of congenital nasolacrimal duct obstruction (CNLDO).

Methods: We conducted a retrospective analysis of cases of post-operative loss of monocanalicular silicone tubes occurring at one medical center from January 2007 to December 2013.

Results: During the study period monocanclicular silicone tubes were lost in 24/54 eyes (44%) of 19/46 children.

Visual prognosis and complications following silicone oil removal.

Purpose: To evaluate the visual prognosis and the occurrence of significant complications after silicone oil removal (SOR) in recent years and compare them to previously published data.

Methods: A total of 89 eyes of 89 patients who underwent SOR and had at least 6 months of follow-up were included in this retrospective study. Recorded parameters included demographic information, previous ocular history, length of silicone oil retention in the eye, visual acuity (VA) and intraocular pressure (IOP) prior to the SOR procedure and throughout the follow-up period, and the occurrence of postoperative complications.

Risk factors for intrauterine fetal death (1988-2009).

Objective: To determine risk factors for intrauterine fetal death (IUFD).

Study Design: A retrospective population-based study, of all singleton deliveries between the years 1988-2009 was conducted. Intrapartum deaths, postpartum death, and multiple gestations were excluded.
