Minneapolis—Differentiating ischemic optic neuropathy from optic neuritis can be problematic. The type of visual field defect, the presence or absence of pain, radiologic differences distinguishing between the two, and the degree of visual recovery, among others, may be helpful clues, Howard D. Pomeranz, MD, PhD, suggested.
San Diego—The M2 130-?m disposable head (Moria) performed well in a small series of patients who underwent LASIK for the treatment of myopia and myopic astigmatism. The faster surgical path used with this device may be responsible for induction of less higher-order aberration.
San Diego—The Artisan Phakic IOL (Ophtec BV, Groningen, The Netherlands) provides overall high satisfaction for patients with moderate to high myopia. Night vision problems from higher-order aberrations, decentration of the lens, and pupil size versus the optic disparity of the IOL should be investigated further, according to Randy Nuijts, MD.
San Diego—The I-CARE anterior chamber foldable phakic IOL (CORNEAL, Paris, France) seems to provide excellent anatomic and visual results 2 years after implantation.
San Diego—Phakic anterior chamber IOLs affect the biometric measurement of axial length, which results in clinically significant errors in IOL power calculations in patients who need to undergo cataract surgery. Gerald Zaidman, MD, described such a patient and offered suggestions for managing this complicated problem here at the American Society of Cataract and Refractive Surgery.
Los Angeles—Hypertension in a patient should raise a red flag for ophthalmologists because it may be associated with optic neuropathy. Anthony C. Arnold, MD, provided his pearls for the safe management of these patients.
Montreal—Acute third-, fourth-, or sixth-nerve palsies do not seem to be associated with myocardial infarctions (MI) and cerebrovascular accidents (CVA), but the development of one of these palsies is an indi- cation for an assessment of ischemic risk factors, according to Kashif Baig, MD, MBA.
Lausanne, Switzerland—Disorders of accommodation can be caused by disruption of neuroregulation. While many patients present with an insidious and mild accommodative insufficiency, often accompanying a systemic illness, the acute onset of severe and bilateral loss of accommodation is a more serious condition and may indicate the presence of a midbrain lesion.
Tampere, Finland-Both the M2 Single Use microkeratome and the M2 microkeratome with the new 90-?m head (Moria, Antony, France) have been performing well in clinical trials.
The HydroKeratome Waterjet System (Visijet Inc.), the first microkeratome that creates a LASIK flap using a continuous beam of ultra-high-pressure water instead of a metal blade, debuted at the 2003 annual meeting of the American Academy of Ophthalmology in Anaheim.
