PURPOSE: Electron therapy for the treatment of ocular lymphomas requires the lens to be shielded to prevent secondary cataracts. This work evaluates the dosimetry under a suspended eyeshield with and without bolus for low energy electron fields. METHODS: Film (GafChromic EBT3) dosimetry and relative output factors were measured for 6, 8, and 10 MeV electron energies. A customized 5 cm diameter circle electron orbital cutout was constructed for a 6×6 cm applicator with a lens shield, 1 cm diameter Cerrobend cylinder with 2...

PURPOSE: To evaluate a chemoreduction regimen using systemic vincristine and carboplatin (VC) and local ophthalmic therapies to avoid external-beam radiotherapy (EBRT) or enucleation in patients with Group B intraocular retinoblastoma. PATIENTS AND METHODS: Twenty-one patients (25 eyes) were treated with six cycles of VC, accompanied by local ophthalmic therapies after cycle 1. The primary study objective was to determine the 2-year event-free survival (EFS) where an event was defined as the use of systemic chemotherapy in addition to vincristine or carboplatin, EBRT, and/or enucleation...

REVIEW
S Kaliki, C L Shields
Although it is a relatively rare disease, primarily found in the Caucasian population, uveal melanoma is the most common primary intraocular tumor in adults with a mean age-adjusted incidence of 5.1 cases per million per year. Tumors are located either in iris (4%), ciliary body (6%), or choroid (90%). The host susceptibility factors for uveal melanoma include fair skin, light eye color, inability to tan, ocular or oculodermal melanocytosis, cutaneous or iris or choroidal nevus, and BRCA1-associated protein 1 mutation...

PURPOSE: To describe two cases of coughing-induced suprachoroidal hemorrhage referred as choroidal melanoma. METHODS: Observational case reports. RESULTS: Two female patients (ages 54 and 60 years) were referred with possible choroidal melanoma. Both gave a history of 1 day of heavy coughing with Valsalva maneuver within 2 weeks before discovery of the tumor. In one case, the patient used anticoagulants for aortic valve replacement and the other patient used antiasthma medications...

PURPOSE: To characterize the clinical features, aetiology and management of ophthalmic symptoms in adult patients with Parinaud syndrome. METHODS: This is a retrospective, non-comparative observational case series. We reviewed 40 consecutive charts of adult patients with the clinical diagnosis of Parinaud syndrome at the Royal Adelaide Hospital Department of Ophthalmology in Adelaide, South Australia, between 1991 and 2016. Charts were reviewed for the following: (1) demographic information, (2) clinical presentation, (3) neuro-ophthalmology signs, (4) aetiology of Parinaud syndrome, and (5) management...

INTRODUCTION: The literature lacks data on accuracy of single fiber electromyography (SFEMG) for myasthenia gravis (MG) patients followed longitudinally. METHODS: We included patients with a clinical suspicion of MG who received SFEMG and follow-up at our institution between 2003 and 2013. Data collected included demographics, symptom details, clinical deficits, other diagnostic testing results, MG medication regimen, duration on treatment, response to therapy, and ultimate diagnosis after follow-up...

PURPOSE: To evaluate whether conjunctival biopsy findings in patients with ocular mucous membrane pemphigoid (MMP) persist as positive or revert to negative following treatment with immunomodulatory therapy (IMT). METHODS: Patients with biopsy-proven MMP were treated with IMT for at least 2 years before undergoing repeat conjunctival biopsy for immunofluorescence microscopy. Their records were reviewed and findings evaluated to ascertain which patients' biopsies showed antibody deposition on the conjunctival basement membrane...

PURPOSE: To investigate the interval between low-dose radiotherapy and radiation-induced cataracts, and the factors affecting this interval, in patients with lymphoproliferative disease of the ocular adnexa. METHODS: A retrospective case series of 73 eyes of 59 patients who underwent radiotherapy from 1996 to 2005 with total doses ranging from 24 to 30 Gy was conducted. We investigated the relationships between the radiation-associated cataract formation intervals and age, gender, diabetes, and the use of corticosteroids...

The retinal dopaminergic system is involved in the myopic shift following form deprivation. Citicoline has been demonstrated to stimulate the dopaminergic system in the brain and retina. Furthermore, citicoline has been used in many neurogenic diseases, such as senile cognitive impairment, stroke and Parkinson's disease as well as in amblyopia and glaucoma. Our aim was to investigate the effect of citicoline on the refractive state and retinal dopamine level in form deprivation myopia of guinea pigs. Guinea pigs, at an age of four weeks, were randomly divided into normal control, deprivation, deprived + citicoline and deprived + vehicle groups...

PURPOSE: Dry eye disease (DED) is potentially associated with sleep and mood disorders. This study evaluated sleep quality in patients with DED using a questionnaire-based survey before and after topical eyedrop treatment. The effectiveness of sleep and ophthalmic services in assisting with sleep problems in patients with eye disease was also assessed. METHODS: Seventy-one consecutive patients with DED visiting eight general eye clinics in various locations answered a questionnaire containing the Pittsburgh Sleep Quality Index and Hospital Anxiety and Depression Scale...

Glaucoma is a common progressive eye disorder which remains the second leading cause of blindness worldwide. Current therapy involves frequent administration of eye drops which often results in poor patient adherence and therapeutic outcomes. The aim of this study was to overcome these limitations by developing a novel nanoparticle cross-linked collagen shield for sustained delivery of pilocarpine hydrochloride (PHCl). Three metal oxide nanoparticles (NPs); titanium dioxide (TiO2), zinc oxide (ZnO) and polyvinylpyrrolidone (PVP) capped zinc oxide (ZnO/PVP), were evaluated for their cytotoxicity as well as shield transparency before selecting ZnO/PVP NPs as the ideal candidate...

REVIEW

Coating the surface of nanoparticles with polyethylene glycol (PEG), or "PEGylation", is a commonly used approach for improving the efficiency of drug and gene delivery to target cells and tissues. Building from the success of PEGylating proteins to improve systemic circulation time and decrease immunogenicity, the impact of PEG coatings on the fate of systemically administered nanoparticle formulations has, and continues to be, widely studied. PEG coatings on nanoparticles shield the surface from aggregation, opsonization, and phagocytosis, prolonging systemic circulation time...
