Gary Vanderzee, Douglas Tassi
BACKGROUND: Toxic retinopathy is an uncommon sequella in the treatment of certain autoimmune diseases with hydroxychloroquine (HCQ). We present two cases of HCQ toxic retinopathy, as well as a discussion on how to diagnose and manage early toxicity findings; CASE REPORTS: Two cases are presented of patients who experienced toxic effects of HCQ therapy. The first patient had bull's eye maculopathy confirmed with visual field testing and optical coherence tomography (OCT)...

REVIEW
Jeffrey Cooper, Erica Schulman, Nadine Jamal
This is a review of the current literature describing the effect of atropine, bifocals, and/or contact lenses on slowing the progression of myopia. Cumulative data from a number of studies have demonstrated atropine instilled once a day in myopic eyes resulted in a 90% average reduction of myopia progression, as compared to untreated eyes, i.e., from 0.50 D/year to 0.05 D/year. Pirenzepine, a muscarinic pharmacological agent, has a minimal effect on pupil size and accommodation, and it has been shown to slow myopia by 44%...

Richard J Zimbalist
BACKGROUND: Diabetic papillopathy is a benign optic neuropathy with a favorable predictable visual outcome, found in Type 1 and Type 2 patients with diabetes mellitus. The condition manifests with optic disc edema and minimal optic nerve dyfunction. Previous reports have described several similarities between diabetic papillopathy and non-arteritic anterior ischemic optic neuropathy; however, there are clinical differences that make them unique conditions; CASE REPORT: A 62 year old Caucasian male with Type 2 diabetes manifested bilateral optic disc edema without visual dysfunction...

INTRODUCTION: Central corneal thickness (CCT) imparts information about an individual's risk of conversion to glaucoma from ocular hypertension, progression of established glaucoma, and the likelihood of developing structural and functional abnormalities in patients with ocular hypertension. Most typically, CCT is measured through ultrasound (US) pachymetry. Currently, optical coherence tomography (OCT) has the ability to image the anterior segment, cornea, and anterior chamber angle...

Melissa Misko
BACKGROUND: Blunt force trauma can affect all structures in the eye, frequently causing complications such as hyphema or microhyphema. A hyphema is defined as bleeding in the anterior chamber that layers and forms a visible clot. A microhyphema occurs when the red blood cells are suspended in the anterior chamber, and do not form a layered clot. Microhyphema is a rarely reported, visually significant complication. Ocular trauma is the second most common cause of visual impairment, and appropriate management must be executed swiftly and efficiently to maximize a patient's visual potential; CASE REPORT: A 21-year-old Indian male presented after ocular contusion to the right eye...

REVIEW
Jeffrey Cooper, Nadine Jamal
Convergence insufficiency is a common binocular vision disorder affecting approximately 5% of the population in the United States. It is often associated with a host of symptoms that occur when doing near work, such as reading and computer viewing. This article reviews the existing literature on convergence insufficiency including etiology, diagnosis, sensorimotor findings, and management.

BACKGROUND: The purpose of this study was to assess monocular and binocular distance perception, and stereoacuity, in individuals with mild traumatic brain injury (mTBI) who reported the symptom of "poor depth perception"; METHODS: Ten patients with mTBI were tested and compared with ten visually-normal asymptomatic individuals in the following areas: perceived distance, stereoacuity at distance (3 meters) and near (40 cm), and a 9-item 5-point rating-scale questionnaire related to distance perception...

#9
Pravina Patel, Julie Rodman
BACKGROUND: Neovascularization can occur in various ocular structures including the retina, iris, anterior chamber angle and cornea; however, it rarely occurs in the crystalline lens. Neovascularization results secondary to hypoxic conditions within the eye. A natural balance of angiogenic and antiangiogenic factors are critical for the eye to prevent the formation of neovascularization. Various factors can upset this natural balance, resulting in angiogenesis. Due to the lack of an intrinsic blood supply, intralenticular neovascularization is rare...

#12
Wendy J Haaland Stone, Erica A Ittner, Bruce A Teitelbaum, Leonard V Messner
BACKGROUND: Chiari I malformation (CM1) is the caudal herniation of the cerebellar tonsils into the foramen magnum. It can cause several neurological signs and symptoms, or be asymptomatic. Papilledema is a potential, but unusual, manifestation of CM1. While CM1 is often asymptomatic, papilledema is less likely to be. We present the first reported case of a progressive, asymptomatic papilledema as the sole presenting sign of a CM1; CASE REPORT: A 39 year old woman presented without neurological symptoms and was found to have optic disc edema...

#13
Edward S Jarka, Mark Kahrhoff, John B Crane
BACKGROUND: Dry eye syndrome (DES) has been described by The International Dry Eye WorkShop as ''multifactorial disease of the tears and ocular surface that results in symptoms of discomfort, visual disturbance and tear instability with potential damage to the ocular surface.'' Inflammation has been recognized as a primary contributor to the disease and was a tremendous step forward in the description and treatment of DES. Although most treatments of DES treat inflammation, the signs and symptoms of DES usually return shortly after discontinuing the use of the anti-inflammatory agent; CASE: We present a case of a 70-year-old patient who presents with significant dry eye symptoms for 2 years...

BACKGROUND: Lipemia retinalis is a well-documented but rate ocular finding directly associated with serum triglyceride levels. The clinical presentation varies with the amount of triglycerides in the blood and completely resolves with lowering triglyceride levels, making this condition transient with no visual symptoms; CASE REPORT: A 46-year old white man presented with lipemia retinalis and, hours later, to the Emergency department with acute pancreatitis secondary to hypertriglyceridemia; CONCLUSION: Lipemia retinalis warrants an immediate complete blood count and lipid panel to Determine triglyceride levels with referral to a primary care provider...

Dustin Dixon, Marc B Taub, Richard Hoenes, W C Maples
BACKGROUND: The visual system is necessary for reading. Understanding the mechanics of eye movements during reading can give insight into the reading process. The ReadAlyzer is an electronic recording system that measures eye movements while reading. Long passages on the ReadAlyzer of 800 words have recently been introduced as a tool to assess the efficiency of reading eye movements. Previously, short passages of 100 words have been used exclusively. This project was designed to determine if passage length influences the quality of reading eye movements; METHODS: Optometry students (N = 40) at Southern College of Optometry were separated into 2 equal groups (symptomatic vs...

We describe the successful translation of computerized and space-consuming laboratory equipment for the treatment of suppression to a small handheld iPod device (Apple iPod; Apple Inc., Cupertino, California). A portable and easily obtainable Apple iPod display, using current video technology offers an ideal solution for the clinical treatment of suppression. The following is a description of the iPod device and illustrates how a video game has been adapted to provide the appropriate stimulation to implement our recent antisuppression treatment protocol...

Denise Goodwin, Ami R Halvorson
INTRODUCTION: Chiari I malformation is a congenital, neurological condition that is characterized by defects of the skull base resulting in herniation of the cerebellum through the foramen magnum into the cervical spinal canal. Because the condition can result in visual symptoms, patients will often search for answers from their eye care providers; CASE REPORT: A 28-year-old Hispanic diabetic male with a 10-year history of nystagmus was referred to the neuro-ophthalmic disease clinic following the initiation of oscillopsia 1 year previous...
