Outcomes of plaque radiotherapy for retinoblastoma
The study authors evaluate their experience of plaque radiotherapy for retinoblastoma (RB) in 41 eyes of 41 patients that failed intra-arterial chemotherapy (IAC). This was a retrospective review including 21 females and 20 males. Median age was 18 months and...
Choroidal and RNFL thickness in patients with OSAS
In obstructive sleep apnoea syndrome (OSAS), hypoxia secondary to repetitive apnoeic episodes leads to blood pressure variations and haemodynamic changes. There is also intermittent activation of the sympathetic system when the patient is aroused from sleep during apnoeic episodes. OSAS...
Is virtual reality perimetry as reliable as static perimetry in detecting neurological visual field loss?
This study compares agreement between virtual reality perimetry (VRP) and static automated perimetry (SAP) in a variety of neuro-ophthalmological conditions. For this work the Order of Magnitude (OM) VR-based visual field assessment system was used which has been developed by...The power of the full blood count
Vishal Shah walks us through his thought process whilst highlighting the importance of routine investigations when dealing with unusual retinovascular presentations. Retinal changes can arise in anaemia, leukaemia, lymphoma, myeloproliferative and myelodysplastic syndrome. They are often the first manifestation of...
RaScaL Study
The RaScaL study was a six month, single-centre, controlled, prospective phase I/II study in which subjects with diabetic macular oedema (DME) and associated peripheral nonperfusion on ultrawide-field fluorescein angiography (UWFA) were randomised to: (1) study arm: ranibizumab (0.5 mg) injection...Radiation retinopathy
The authors review the current treatment options for this condition. Radiation retinopathy (RR) occurs as a complication after exposure to any type of radiation (external beam, plaque brachytherapy and stereotactic radiosurgery) in the orbital or adnexal region. These include nasopharyngeal...
Association between neurodegeneration and macular perfusion in the progression of diabetic retinopathy
In this prospective three-year longitudinal study, the authors aimed to explore the relation between retinal neurodegenerative changes and vessel closure (VC) in individuals with non-proliferative diabetic retinopathy (NPDR). The participants included 74 individuals with type 2 diabetes, NPDR, and Early...Sixth nerve palsy versus decompensating distance esophoria
Orthoptists see a wide range of conditions that can range from reduced binocular single vision (BSV) that may be solved with exercises, to more extreme neurogenic cases requiring further intervention. Because of this variety, it is important to be able...
Optical Coherence Tomography: A Clinical and Technical Update
This book is a comprehensive review of the clinical and scientific aspects of optical coherence tomography (OCT). The 255 pages are divided into 11 chapters, each written by a different group of authors. Part I provides viewpoints on the clinical...
Clinical Pathways in Neuro-Ophthalmology: An evidence based approach (Third edition)
This is a fairly comprehensive textbook with 20 chapters covering the most common neuro-ophthalmic problems you are likely to encounter in clinical practice. The chapters each comprise several sections, the titles of which are often phrased as questions the reader...
