REVIEW
Dirk Dressler, Peter Roggenkaemper
Botulinum toxin (BT) has long been infamous in food safety and biological warfare. In the early 1970s, Alan B Scott of San Francisco invented its therapeutic use originally in extraocular eye muscles to treat strabismus using a therapeutic BT type A preparation provided by Edward J Schantz and Eric A Johnson. Subsequently a large number of medical indications based on motor and glandular hyperactivity and-most recently-chronic migraine are now treated by BT therapy. BT's highly specific and elaborate mechanism of action represents a completely novel therapeutic principle which will have consequences far beyond existing indications...

Amniotic membrane (AM) transplantation has been used successfully worldwide in ophthalmology plastic surgery for over 100 years. This review presents the histological and the immunohistochemical features of AM compared to those of the conjunctiva and discusses the techniques of processing and preservation, its mechanism of action in ocular reconstruction, its clinical ophthalmic indications, but also advantages and limitations of grafting with this biomaterial.

A systematic review of the recent literature regarding pseudophakic monovision as a reliable methods for presbyopia correction was performed based on the PubMed, MEDLINE, Nature and the American Academy of Ophthalmology databases in July 2015 and data from 18 descriptive and 12 comparative studies were included in this narrative review. Pseudophakic monosvision seems to be an effective method for presbyopia with high rates of spectacles independence and minimal dysphotopsia side-effects, that should be considered by the modern cataract surgeons...

INTRODUCTION: The purpose was to investigate the effect of vergence reeducation on postural control, in subjects with isolated vergence disorders. MATERIAL AND METHODS: We studied the dynamics of vergence in 19 subjects (20-44 years old) using video-oculography (Eye See Cam). On the basis of orthoptic and symptomatology assessments, ten of the subjects were diagnosed for vergence disorders then vergence eye movements were reeducated with the REMOBI method (US8851669, 5 weekly sessions lasting for 35min)...

BACKGROUND: Nevus of Ota is a rare disease most frequently found in Asians. It presents clinically as a bluish gray hyperpigmentation of one side of the face. Transformation into melanoma and glaucoma are the main risks. The appearance of vitiligo lesions with poliosis within a nevus of Ota is exceptional. PATIENTS AND METHODS: A 22-year-old female patient with a nevus of Ota consulted for depigmentation of the eyelashes. Physical examination revealed hyperpigmentation in the right orbitofrontal part of her face, achromic macules and eyelash poliosis...

Purpose: Ocular and systemic measurement and imaging of the macular carotenoids lutein and zeaxanthin have been employed extensively as potential biomarkers of AMD risk. In this study, we systematically compare dual wavelength retinal autofluorescence imaging (AFI) of macular pigment with skin resonance Raman spectroscopy (RRS) and serum carotenoid levels in a clinic-based population. Methods: Eighty-eight patients were recruited from retina and general ophthalmology practices from a tertiary referral center and excluded only if they did not have all three modalities tested, had a diagnosis of macular telangiectasia (MacTel) or Stargardt disease, or had poor AFI image quality...

INTRODUCTION    The corrective effect of carotid endarterectomy (CEA) on disturbed ophthalmic artery flow in patients with a significant internal carotid artery stenosis (ICAS) presenting with ocular ischemic syndrome (i.e., symptomatic patients) is well established. However, no clear evidence exists regarding the efficacy of CEA for improvement of neuro-retinal function in patients without symptoms of ocular ischemic syndrome. OBJECTIVES    We determined the effects of CEA on retinal function in asymptomatic patients with hemodynamically significant internal carotid artery stenosis...

We aim to report an unusual case of myelinated retinal nerve fibers (MRNFs) at fovea. A 39-year-old woman presented with visual impairment and her visual acuity was 20/80 in the right eye. Ophthalmologic examination revealed MRNF lesions at inferior and superior poles of optic disc in the right eye. Furthermore, a ring-shaped MRNF lesion with feathery edges was observed at fovea. MRNF lesions are rarely seen at macula, and to our knowledge, this is the first report of an MRNF lesion at fovea.

The incidence of the craniofacial cleft is rare ranging between 1.43 and 4.85/100,000 births. Tessier number nine cleft being the rarest, there are a few reports of detailed ophthalmologic examinations performed in them. In this study, 1-day-old female neonate delivered by normal vaginal delivery at term, weighing 1480 g presented with right eye dystopia, cleft extending through the lateral third of the upper eyelid, brow ending at the temporal region, conjunctival congestion, clear cornea 10 mm in diameter, normal anterior chamber, pupil 2 mm reactive to light, clear lens, and normal fundus...

PURPOSE: Ophthalmologists serve an increasing volume of a growing elderly population undergoing increasingly complex outpatient medical care, including extensive diagnostic testing and treatment. The resulting prolonged patient visit times ("patient flow times") limit quality, patient and employee satisfaction, and represent waste. Lean Six Sigma process improvement was used in a vitreoretinal practice to decrease patient flow time, demonstrating that this approach can yield significant improvement in health care...

RATIONALE: Occlusive cerebrovascular disease is the most common cause of homonymous hemianopia (HH) with macular sparing. PATIENT CONCERNS: A 61-year-old man came to our ophthalmology clinic complaining of right-side hemianopia. Ophthalmic examination, visual field (VF) examination, and brain magnetic resonance imaging (MRI) were performed. DIAGNOSES: He had right HH without macular sparing on the initial VF test. And brain MRI 6 days after the visual symptoms began revealed a left occipital infarction...

Hidrocystomas are benign, cystic lesions of eccrine and apocrine sweat glands. The literature on hidrocystomas is sparse, consisting of a handful of case reports and limited retrospective reviews. This is the first known bi-institutional, retrospective, chart review aimed to elucidate the demographics and basic clinical presentation of hidrocystomas. Medical records of adult patients with a pathological diagnosis of hidrocystoma from September 1, 2008 to August 1, 2015 in the Oculoplastic and Reconstructive Surgery Service at the Illinois Eye and Ear Infirmary (UIC) and Department of Ophthalmology of Weill Cornell Medical College (Cornell) were reviewed...

BACKGROUND: It has been approximately 70 years since the discovery of the Zika virus (ZIKV). It had been established that the virus causes mild infections, and is confined to Africa and Asia; however, major changes in the clinical and epidemiologic patterns of ZIKV infection have occurred in recent years. The virus has attracted intense interest because of the possible association of several autoimmune and neurodevelopmental disorders. METHODS: We present a summary of the articles that attempt to explain the ZIKV unknowns, and strengthen the association with some disorders that are thought to be related to ZIKV, by describing the discovery milestones from the initial identification of the virus to the present day...

PURPOSE: To produce an internationally valid tool to assess skill in performing trabeculectomy surgery. METHODS: A panel of 5 experts developed a tool for assessing trabeculectomy surgery by using a modified Dreyfus scale of skill acquisition and providing descriptors for each level of skill for each category. The tool was then reviewed by a panel of 10 international content experts for their constructive comments, which were incorporated into the final rubric tool...
