The Epidemiology of Visual Disability Studies of Visually Disabled People in the Community [PDF]

, 1977
Review of the world literature on attempts to discover how many people are disabled by poor sight suggested that estimates of prevalence and cause have been constantly hampered by differences of definition, and the difficulties inherent in equating ...

Sutureless Cataract Surgery: Principles and Steps

Community Eye Health Journal, 2003
Introduction. Cataracts cause about 50% of world blindness. There is little likelihood of effective prevention becoming available in the next few years and so the only treatment will remain surgical. For many of the other major causes of world blindness,

Femtosecond‐Laser Nanocavitation Regenerates SERS‐Active Plasmonic Nanogaps for Longitudinal Molecular Sensing at Biointerfaces

Advanced Science, EarlyView.
A regenerative molecular sensing platform that co‐localizes surface‐enhanced Raman spectroscopy (SERS) sensing and nanocavitation‐based actuation. Femtosecond‐laser triggered nanocavitation produces thermomechanical forces to locally regenerate SERS‐active nanogaps in protein‐rich biofluids while preserving optical performance.

Gene Correction Enhances Dopaminergic Cell Therapy in a Nonhuman Primate Model of Parkinson's Disease

Advanced Science, EarlyView.
LRRK2‐mutant induced pluripotent stem cells (iPSCs) were derived from a patient with Parkinson's disease (PD). Using CRISPR/Cas9–mediated gene editing, the pathogenic LRRK2 mutations were precisely corrected, and isogenic dopaminergic neural progenitor cells (DA‐NPCs) were subsequently generated.

Inherited Retinal or Optic Nerve Disorders – Five Steps to Diagnosis (Originaltitel: Erbliche Netzhaut- und Sehbahnerkrankungen – 5 Schritte zur Diagnose) [PDF]

, 2015
An early diagnosis of inherited retinal or optic nerve disorders is often delayed due to unspecific clinical signs, multiple clinical manifestations and striking genetic heterogeneity of the underlying molecular defects.

Axenfeld-Rieger syndrome

Revista Electrónica Dr. Zoilo E. Marinello Vidaurreta, 2018
Axenfeld-Rieger syndrome is a rare congenital disease that has an autosomal-dominant inheritance pattern. The ophthalmic disorder with the dysgenesis of the anterior segment is what defines the disease. This study presents the case of a 9-month-old still-

Renal Clearable Luminogenic Reporter for Ultrasensitive Influenza Virus Imaging and Efficient Antiviral Therapies Monitoring in Living Mice

Advanced Science, EarlyView.
A viral luminogenic reporter with chemiluminescence/fluorescence dual‐response and efficient renal clearance was developed for non‐invasive imaging and urinalysis of H1N1 virus protease, allowing for remote detection of H1N1 virus infections and monitoring of antiviral therapeutic efficacy in living mice.
