A 26-year-old African American female presented to the Bascom Palmer Eye Institute emergency room with complaints of progressively decreasing vision in both eyes over the past 2 weeks associated with numbness on the right side of her face and mouth. She also had symptoms of light sensitivity but denied flashes, floaters, or other ocular symptoms. She denied any other recent illnesses, drug usage, exposure to parasites, infections, or risk factors for HIV.
The clinical exam remains the key to ophthalmologists' decision-making related to the diagnosis and determination of progression of glaucoma. "Baseline" technology in ophthalmology practices includes the slit lamp, some lenses, a gonio prism, an automated perimeter, a pachymeter, and optic nerve imaging capability. Other technology, however-such as confocal scanning laser ophthalmoscopy; nerve fiber layer imaging devices capable of scanning laser polarimetry and optical coherence tomography (OCT); and some anterior segment imaging technologies, including ultrasound biomicroscopy and anterior segment OCT-do not yet have absolute sensitivity and specificity and serve as aids to, not replacements for, the ophthalmologist.
Data analyzed from a total of 568 eyes included in a prospective study of Descemet's stripping automated endothelial keratoplasty indicate that the time from donor death to surgery affects endothelial cell density loss and risk of graft dislocation, but more data are needed to understand possible associations better.
The most common adjusting error that opticians make is temples fitted too close to the patient's head. When this mistake and others are seen it means that somewhere an optician has been improperly trained and is making the mistake on a daily basis.
Evaluation of corneal topography and the ocular wavefront are critical in screening and treating refractive surgery candidates. The diagnostic tools needed to perform these assessments continue to improve.
A proprietary high-resolution spectral-domain optical coherence tomograph (Spectralis, Heidelberg Engineering) offers many advantages to clinicians, such as superior image quality, true multimodal imaging, and improved monitoring of disease progression, says one doctor.
Luxottica Group is carrying out a number of cost-cutting measures, including store closings, manufacturing reductions, and cuts in advertising. These changes came after the company's net income in 2008 fell to €395 million, down 17.6%.
The future will bring an influx of glaucoma patients due to an aging population as well as more patients with angle-closure glaucoma, stemming from an influx of immigrants. Increasing the efficiency of the clinical and business sides of the glaucoma practice is a must for survival in this changing environment. Some procedures that can increase cost efficiency include gonioscopy and tailoring visual field testing to the patient.
One needs to have an understanding of materials, designs, and changes in processes of manufacture to appreciate today's high-tech quality options. Knowing where materials and designs originated helps in seeing the road from which we traveled, as well as gaining insight into where we are going in the world of ophthalmic lenses.
A number of factors should be considered when choosing a spectral-domain optical coherence tomography system. Although the capabilities of many systems essentially are similar, some differences exist based on ease of image acquisition and quality, software versatility, and other factors that may make them the best choice for a specific practice's needs. Proprietary technology (RTVue-100, Optovue Inc.) has the capability to perform both retinal and anterior segment imaging, which may make it a versatile instrument for a general ophthalmology practice, according to one practitioner.
San Francisco-Results of a study using scanning electron microscopy (SEM) analysis to study the ultrastructural characteristics of lamellar flap specimens and stromal beds show marked differences depending on the instrument used for flap creation. The variation noted may have implications for clinical outcomes, said Renee D. Solomon, MD.
San Francisco-Capsular tension rings enhance the optical performance of multifocal IOLs by ensuring centration of the lens and reducing irregularities in the posterior capsule such a folds and wrinkles, said Tobias Neuhann, MD, director, AaM Augenklinik am Marienplatz, Munich, Germany.
San Francisco-A new system combining a modified Shack Hartmann wavefront sensor with a new streamlined phoropter makes measurement of refractive error simpler, more efficient, and more accurate, said Gholam A. Peyman, MD.
