Ting Yin Lu, Kathreena Kadir, Wei Cheong Ngeow, Siti Adibah Othman
This study aimed to determine the prevalence of double eyelid among two main Mongoloid ethnicities, the Malays and Chinese who reside in Malaysia. We also measured their periorbital tissue parameters for application in anthropology, optometry, ophthalmology, oculoplastic surgery and maxillofacial trauma surgery. The images of the 103 Malay and 97 Chinese volunteers were captured using indirect 3D photogrammetry, and quantitative measurement was obtained using the software provided by the manufacturer. All Malays and 70...

Albert Y Wu, Michael G Daniel
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...

Presented is a rare case of basaloid adenocarcinoma of the lacrimal sac. Low grade features of this malignancy permitted a conservative surgical approach to maximize functional and cosmetic outcomes. This is retrospective case description of a single 77-year-old-female patient who underwent a dacryocystorhinostomy with silicone tubes at an outside hospital for epiphora, but was referred to the Wills Eye Hospital Oculoplastics Department for a lacrimal sac biopsy showing low-grade carcinoma with basaloid features...

AIMS: This study describes different types of orbital osteoma based on clinical per-operative morphology and radiological findings to facilitate communication between ophthalmologists and surgical management for a better patient outcome. MATERIALS AND METHODS: The study was conducted in the Orbit and Oculoplastics Department of Al-Shifa Trust Eye Hospital, Rawalpindi, Pakistan, from July 1, 2001 to June 30, 2014. A retrospective analysis of 520 diagnosed orbital tumours who presented to us was carried out and the prevalence of orbital osteoma was determined...

PURPOSE OF REVIEW: Significant advances have been made in oncology and rheumatology with the introduction of molecularly targeted agents (MTAs). MTAs consist of monoclonal antibodies and small molecule inhibitors. The purpose of this manuscript is to review the recent applications of MTAs to orbital, lacrimal, and eyelid disease. RECENT FINDINGS: The use of monoclonal antibodies has been described in the treatment of orbital vascular lesions, lymphoma, and squamous cell carcinoma...

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...

BACKGROUND/AIMS: To compare the ocular biomechanical properties in patients with thyroid eye disease (TED) and healthy participants using a non-contact Scheimpflug-based tonometer (CorVis ST). METHODS: All eyes were examined by slit lamp biomicroscopy, corneal tomography and the CorVis ST (CST). Patients with TED were examined by a fellowship trained oculoplastics specialist to determine status and assess severity. The outputs from CST and additionally derived parameters, including maximum orbital deformation (MOD), were compared between healthy participants and patients with TED using Student's t-test...

PURPOSE OF REVIEW: The review examines the utility of stem cell biology in ophthalmology and oculoplastic surgery. RECENT FINDINGS: The applicability of stem cell biology varies across a range of different subfields within ophthalmology and oculoplastic surgery. Resident stem cells have been identified in the lacrimal gland, corneal limbus, orbital fat, and muscles of the eye, and can potentially be applied for in-vitro cell and organ cultures with the intent of disease modeling and transplants...

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...

We present a case of a 26-year-old man who sustained a close-range gunshot wound to the head. His injuries included significant left orbital injury resulting in a ruptured, blind eye and severely comminuted fractures of the left orbital roof, superior and inferior orbital rims, and orbital floor. Associated injuries included left frontal lobe injury, anterior and posterior table fractures of the left frontal sinus, and a comminuted left zygomaticomaxillary complex fracture. We employed an interdisciplinary surgical approach with collaboration among the Otolaryngology, Neurosurgery, and Oculoplastic Surgery services performed in two stages...

The purpose of the current research was to reevaluate the normative data on the eyeball diameters. Methods. In a prospective cohort study, the CT data of consecutive 250 adults with healthy eyes were collected and analyzed, and sagittal, transverse, and axial diameters of both eyeballs were measured. The data obtained from the left eye and from the right eye were compared. The correlation analysis was performed with the following variables: orbit size, gender, age, and ethnic background. Results. We did not find statistically significant differences correlated with gender of the patients and their age...

INTRODUCTION: We report a rare case of epidemic keratoconjunctivitis (EKC) that developed into an orbital inflammation in an adult. CASE PRESENTATION: A 67-year-old Korean man, who had been diagnosed with EKC and treated for conjunctival injection and chemosis in the right eye for 4 days, was referred to Oculoplastics as orbital cellulitis was suspected. At the point of referral, clinical features such as decreased visual acuity, severe eyelid swelling, chemosis, follicles, corneal edema, limitations in lateral eye movement, and diplopia were observed in the right eye...

Measurement of periocular structures is of value in several clinical specialties including ophthalmology, optometry, medical and clinical genetics, oculoplastic surgery, and traumatology. Therefore we aimed to determine the periocular anthropometric norms for Chinese young adults using a noninvasive 3D stereophotography system. Craniofacial images using the 3dMDface system were acquired for 103 Chinese subjects (51 males and 52 females) between the ages of 18 and 35 years. Anthropometric landmarks were identified on these digital images according to standard definitions, and linear distances between these landmarks were calculated...
