PURPOSE To study the influence of stereoscopic depth perception on automobile driving performance. METHODS Ten patients with strabismus and defective stereopsis were compared with ten healthy controls with respect to their performance in a series of automobile driving manoeuvres. The two groups were individually matched as to age, annual miles driven,(More)
INTRODUCTION Because kinetic perimetry is performed manually, it is difficult to standardize. This study evaluated the effect of different velocities of various stimuli on the results of automated kinetic perimetry. MATERIALS AND METHODS Twelve ophthalmologically healthy subjects were tested with stimuli III4, I4, I2, I1 using the Twinfield perimeter at(More)
BACKGROUND The optimal age for surgery for infantile esotropia is controversial. Proponents of early surgery believe that further loss of binocular vision can be prevented by early surgery, a minority believes that binocular vision can even be restored by early surgery. The ELISSS compared early with late surgery in a prospective, controlled,(More)
PURPOSE To elucidate the aetiology of congenital Brown syndrome. METHODS Four consecutive patients diagnosed with unilateral congenital Brown syndrome had a comprehensive standardized ocular motility examination. Any compensatory head posture was measured. Brain magnetic resonance imaging (MRI) with regard for the IV cranial nerve (CN) was performed in(More)
Infantile esotropia (IE) is defined as an esotropia before the age of 6 months, with a large angle, latent nystagmus, dissociated vertical deviation, limitation of abduction, and reduced binocular vision, without neurological disorder. Prematurity, low birth weight, and low Apgar scores are significant risk factors for IE. US standard age of first surgery(More)
Vision through the endoscope is strictly monocular. Perception of depth (stereopsis) during ethmoid surgery through the operating microscope would be expected to be superior due to binocular view. To investigate whether monocularity of the endoscope is a disadvantage in paranasal sinus surgery, we compared stereoacuity in a model of the nasal cavity using a(More)
PURPOSE To describe a patient with unilateral ptosis caused by localized amyloid deposits of immunoglobulin lambda-light chains (A-lambda-amyloid) in the levator palpebrae muscle. STUDY DESIGN Case report and literature review. PARTICIPANT A 32-year-old otherwise healthy female with right-sided unilateral ptosis. METHODS The patient presented with(More)
Patients with a preoperatively detached macula and operated upon between October 1976 and July 1978 were analyzed for three parameters of macular function after surgical repair. Reattachment was achieved by cryopexy, an external sponge plombage and nondrainage. The observation period was a minimum of 1 year. Visual acuity increased in all patients with a(More)
INTRODUCTION The purpose of the study is the development of a scoring system for the assessment of functional impairment due to visual field defects, based on the Esterman grid, but adapted to the existing system in the Federal Republic of Germany. METHODS The score areas and the evaluation rules were altered iteratively, until the functional score by the(More)
PURPOSE Continuous light increment perimetry (CLIP) is an improved testing strategy for automated static perimetry designed to save test time and enhance patient compliance. CLIP uses a modified ramp stimulus where stimulus intensity is continuously increased according to patient reaction time, starting from a subthreshold intensity until recognition. The(More)
