Purpose: To review long time treatment results in patients with small or medium sized choroidal melanoma who underwent surgical tumor endoresection as a primary treatment when plaque radiotherapy was unable and patients declined enucleation. Materials and methods: Patients were evaluated for best corrected visual acuity (BCVA), and underwent biomicroscopy, indirect ophthalmoscopy, retinography and ultrasound as well as the usual systemic workup. Study inclusion required the absence of scleral invasion or metastasis and an anterior margin not exceeding the pars plana or the ciliary body...

Objective: To examine the features and values of ultrasonic diagnosis for retinal detachment in eyes with silicone oil tamponade (SOT). Methods: A prospective study. A total of 257 eyes (257 patients) were filled with silicone oil between December 1, 2015 and August 1, 2016 in the Department of Ophthalmology at a hospital in Beijing. All of the patients underwent a color Doppler ultrasound examination in the supine and sitting positions a week prior to surgery. The pre-surgery conditions were compared with the subsequent observations during the surgery to analyze the features and values of ultrasonic diagnosis for retinal detachment in eyes with SOT...

PURPOSE OF REVIEW: We review new applications of optical coherence tomography (OCT) technology in neuro-ophthalmology. We also describe new technologies for visualizing the extracranial vessels in the diagnosis of giant cell arteritis (GCA). RECENT FINDINGS: Newer OCT modalities are expanding the evaluation of the optic disc, and are being applied to a number of neurologic conditions such as demyelinating and neurodegenerative disease. Swept-source OCT and enhanced-depth imaging OCT are refining the fine-grained analysis of the optic nerve head in the diagnosis of papilledema and optic nerve drusen...

PURPOSE: The aim of the study was to identify potential failure modes (FMs) having a high risk and to improve our current quality management (QM) program in Collaborative Ocular Melanoma Study (COMS) ocular brachytherapy by undertaking a failure modes and effects analysis (FMEA) and a fault tree analysis (FTA). METHODS AND MATERIALS: Process mapping and FMEA were performed for COMS ocular brachytherapy. For all FMs identified in FMEA, risk priority numbers (RPNs) were determined by assigning and multiplying occurrence, severity, and lack of detectability values, each ranging from 1 to 10...

Background Advanced cataract with hard lens nuclei frequently challenge the ophthalmologic surgeon when doing phacoemulsification. In the present study, we examined the effect of a new phaco tip design during cataract surgery. Patients and Methods 100 patients were assigned to two groups. In group 1 (50 patients), the Kelman(®) tip design (Alcon) was used during phacoemulsification, while in group 2 (50 patients), the Intrepid(®) Balanced Tip was applied. Trypan blue was used in both groups, if necessary, to stain the anterior lens capsule prior to capsulorhexis...

BACKGROUND AND STUDY AIMS: Neonatal cholestasis can be associated with ocular findings that might aid in its diagnosis, e.g., Alagille syndrome (AGS) and Niemann Pick disease (NPD). We aimed to investigate the frequency of ocular manifestations in infants with cholestasis. PATIENTS AND METHODS: This cross-sectional study included cholestatic infants presenting to the Paediatric Hepatology Unit, Cairo University Paediatric Hospital, Cairo, Egypt. All infants underwent examination of lid, ocular motility, anterior and posterior segments and measurement of intraocular pressure, cycloplegic refraction, ocular ultrasonography and vision...

PURPOSE: The aim of this study is to report surgical outcomes in patients undergoing phacoemulsification surgery (PE) with versus without ophthalmic viscosurgical devices (OVDs). METHODS: This is a comparative case series study. In total, 145 patients who performed PE with OVDs in 68 eyes (Group 1) and without OVD in 77 eyes (Group 2) were enrolled. A comprehensive ophthalmological examination was performed including slit-lamp, fundus examination. Best-corrected visual acuity (BCVA), intraocular pressure (IOP) specular endothelial microscopy (SM), and ultrasound pachymetry (UP) were also measured before surgery and at four-time points postoperatively...

A 40-year-old male presented to the ophthalmology clinic with a darkly pigmented infratemporal lesion in his right eye. The corrected visual acuity in both eyes was 6/6 and both pupils were equal and reactive. Slit lamp biomicroscopy showed a well-demarcated and heavily pigmented lesion in the peripheral iris between 6 and 8 o'clock. Ultrasound biomicroscopy (UBM) revealed a solid mass deriving from the iris stroma without ciliary body involvement, helping to classify the uveal melanoma and establishing the diagnosis of iris melanoma...

REVIEW
C J Schankin, A Straube, C L Bassetti, U Fischer
Headache is one of the most frequent symptoms leading to visits at the emergency department. Here, we aim at presenting a pragmatic algorithm for headache patients at the emergency department. The basic principle is taking a detailed history of the current headache with a focus on dynamics, phenotype and trigger factors as well as a possible preexisting headache. "Red flags" should be interrogated specifically. Hypotheses of the etiology of the headache should be generated in combination with the clinical examination (vital signs, neurological exam, otorhinolaryngological and ophthalmological exams) and should be tested appropriately with imaging, laboratory, cerebral spinal fluid studies and ultrasound...
