An 8-year-old girl was referred for an amelanotic iris tumor believed to have enlarged slightly over 3 months, suspicious for juvenile xanthogranuloma (JXG). The affected right eye had a lightly pigmented, vascular iris mass measuring 6 mm in basal dimension and 2 mm in thickness. There were no feeder vessels, seeding, inflammatory cells, or cutaneous abnormalities. Diagnostic fine needle aspiration biopsy (FNAB) was performed, revealing spindle B melanoma cells that were immunoreactive for melanocytic markers HMB45 and Melan-A...

Primary conjunctival rhabdomyosarcoma (RMS) is a rare entity that can present with or without papillomatous features. A 5-year-old Asian boy was referred for a rapidly growing conjunctival tumor in the superior fornix of the left eye. Surgical excision yielded a 28 mm multilobulated papillomatous specimen that exhibited histopathologic and immunohistochemical features consistent with embryonal (botryoid) RMS. Molecular analysis revealed the absence of the PAX3/FOXO1 fusion gene, indicating favorable prognosis...

Over recent years, hand-held optical coherence tomography (HH-OCT) has become critical for retinoblastoma diagnosis and management. We report precise HH-OCT findings in a case of sub-millimeter retinoblastoma treated with foveal-sparing indocyanine green-enhanced transpupillary thermotherapy (ICG-TTT). A 2-month-old Caucasian female with bilateral Group B retinoblastoma showed two recurrent macular tumors in the right eye, demonstrating 88 μm and 37 μm of growth to 344 μm and 413 μm in thickness, respectively, on HH-OCT...

PURPOSE: The purpose of this study is to report on treatment outcomes for medium-sized choroidal melanoma treated with Ruthenium-106 (Ru-106) plaque brachytherapy. METHODS: A retrospective case series of 28 patients received Ru-106 brachytherapy treatment for choroidal melanoma. The prescribed tumor dose was 85 Gy to a depth of 5 mm. RESULTS: Median follow-up was 31.2 months. At 12 and 24-month postirradiation, the best corrected visual acuity ≥20/70 (LogMar ≥-0...

PURPOSE: Data on basal cell carcinoma (BCC) from the Middle East are deficient. We present the features and management outcomes for BCC over the last 36 years in Saudi Arabia. SUBJECTS AND METHODS: This retrospective chart review included BCC patients diagnosed and treated at Saudi Arabia between 1980 and 2016. Data were collected on patient demographics, clinical and histopathological characteristics of the lesions, management, and follow-up. RESULTS: One hundred and twenty-six patients with BCC were included in this study...

REVIEW
Yağmur Seda Yeşiltaş, Ahmet Kaan Gündüz
Idiopathic orbital inflammation (IOI) is a benign inflammatory condition usually confined to the orbit but extraorbital extension can also occur. IOI has been classified into categories including anterior, diffuse, posterior or apical, myositis, and dacryoadenitis. Other rare types of IOI include periscleritis, perineuritis, and focal mass. Diagnosis is based on careful history, clinical findings, computed tomography, and magnetic resonance imaging findings. An orbital biopsy is usually done for accessible orbital lesions such as dacryoadenitis...

REVIEW
Hany S Hamza, Abdelrahman M Elhusseiny
Uveal melanoma is the most common intraocular malignant tumor, with the choroid being the most common site. Management of choroidal melanoma has evolved greatly over the past years. In the past, the conventional method of treatment was enucleation of the affected eye with a debate regarding the effect of enucleation to promote or prevent metastasis. However, nowadays, there are many therapeutic options available including plaque radiotherapy, proton beam radiotherapy, argon laser photocoagulation, transpupillary thermotherapy, stereotactic radiotherapy using gamma knife, enucleation, and surgical resection of the tumor whether through transscleral approach "Exoresection" or less commonly through internal resection approach "Endoresection...

REVIEW
Richard Cutler Allen
Incidental orbital masses that are asymptomatic and appear benign are often observed without surgical intervention unless there is a clinical or radiographic change in the mass. There is a burgeoning population of cancer patients with incidental masses that have been detected while under surveillance for metastasis. This population of patients is growing due to a number of reasons, including more extensive imaging, an aging population, and more effective cancer treatments. Closer scrutiny should be applied to these patients, due to the possibility of the mass being an orbital metastasis...

Orbital floor fractures alone or in conjunction with other facial skeletal fractures are the most commonly encountered midfacial fractures. The technological advances in 3-dimensional (3D) printing allow the physical prototyping of 3D models, so creates an accurate representation of the patient's specific anatomy. A 56-year-old Caucasian man with severe hypoglobus and enophthalmos with an extensive blowout fracture was scheduled for reconstruction. First, 3D physical models were created based on the computed tomography scan datasets from patient...

Abdulrahman AlDarrab, Rizwan Malik
Aniridia-associated glaucoma is often refractory to medical treatment. Glaucoma drainage device surgery is often considered after failed angle surgery. However, the potential complications of tube surgery in young children are not negligible. The failure rate of conventional trabeculectomy may be high and can require close and multiple postoperative follow-up visits. Here, we describe a child with aniridia who achieved good short-term results with deep sclerectomy. A 14-month-old girl was referred to our unit following bilateral trabeculotomies for aniridia-associated glaucoma and persistent uncontrolled intraocular pressure (IOP) in both eyes...

Palmoplantar keratodermas (PPKs) are a rare heterogeneous group of disorders characterized by abnormal thickening of the skin of palms and soles. Ocular manifestations reported with palmer planter keratosis include scleral melanosis, macular deposits, and congenital cataract. We report, for the first time, a case of bilateral keratoconus in a patient with PPK.

Aliyah Hadi Alameri, Donald Ural Stone
Exposure of the suture after transscleral suture fixation of posterior chamber intraocular lenses is a known late complication that typically requires intervention. Patch grafts of sclera, cornea, or pericardium have been described. We describe a novel autologous scleral flap to cover an exposed 10-0 polypropylene suture. This technique requires no exogenous graft material and avoids the risks of intraocular manipulation of the lens. Every effort should be made to avoid external exposure of the suture, but in cases that develop suture erosion, an autologous scleral flap may be a useful intervention...

PURPOSE: To report the causes of permanent severe visual impairment and blindness among Jordanian blind people. MATERIALS AND METHODS: This study was conducted on 1422 legally blind or worse vision people of all ages who attended the ophthalmic division of a medical committee for evaluation of disabled persons from July 2013 through November 2014. They were divided into two age groups: adult group (998 cases) and childhood group (<16 years, 424 cases). Patients presented reports from their ophthalmologists detailing their eye examination including best-corrected visual acuity, slit-lamp examinations, and if applicable, intraocular pressure, dilated ophthalmoscopy, and visual field and the primary cause of visual impairment...

AIM: This study aims to study normative choroidal thickness (CT) and Haller's and Sattler's layers thickness in normal Indian eyes. MATERIALS AND METHODS: The choroidal imaging of 73 eyes of 43 healthy Indian individuals was done using enhanced depth imaging feature of spectralis optical coherence tomography. Rraster scan protocol centered at fovea was used for imaging separately by two observers. CT was defined as the length of the perpendicular line drown from the outer border of hypereflective RPE-Bruch's complex to inner margin of choroidoscleral junction...
