Vertical disparity nulling in random-dot stereograms.

Abstract

Vertical alignment of monocularly visible structures has profound influence on a binocular system's ability to fuse high spatial frequencies of a random-dot stereogram. We show that monocular objects "capture" the vertical alignment: often less than 5% of the total stereogram area determines the state of the vertical alignment and can prevent fusion of the fine scale detail. This suggests that the human binocular system uses a heuristic in which, when monocularly salient information is available, stereomatching is attempted only at vertical alignment settings determined by the monocular structures.

Asymmetrical bilateral paresis of the superior oblique muscle.

BACKGROUND: To review the preoperative signs of bilateral superior oblique paresis and to analyze their presence. METHODS: The proposed preoperative signs of bilateral superior oblique (SO) muscle paresis were separated into "certain signs" and "suspicious signs." The signs were analyzed for accuracy using case examples and statistics. RESULTS: A strong preoperative sign of bilateral SO muscle paresis was reversal of the hypertropia in the ipsilateral (and/or ipsi-supralateral) position and/or in the contralateral head tilt position. In such cases, the addition of a light contralateral weakening procedure to the operation aimed at the elimination of the hypertropia caused by the more affected SO muscle prevented development of the clinical picture of a contralateral SO muscle paresis. A suggestive preoperative sign of bilateral SO muscle weakness was marked reduction of the hypertropia in the ipsilateral (and ipsi-supralateral) position, as well as in the contralateral head tilt position. In these cases, a contralateral inferior oblique muscle weakening was deferred until after motility could be reassessed postoperatively. An additional sign of possible bilateral SO muscle weakness was the presence of a large V pattern. CONCLUSIONS: When planning surgery for apparent unilateral SO muscle paresis, the surgeon should be aware of the often subtle preoperative signs of bilateral SO muscle paresis. Early diagnosis allows the surgeon to avoid the reversal of the clinical picture or to advise the patient of the possibility of a bilateral problem.

The diagnosis and treatment of infantile nystagmus syndrome (INS).

The successful treatment of infantile nystagmus syndrome (INS) depends primarily on accurate and repeatable diagnosis of the type(s) of nystagmus present as well as their variation with gaze and convergence angles or fixating eye. Research over the past 40 years has demonstrated that the only way to achieve both is by making and analyzing ocular motility recordings. Determination of the direct effects of peripheral and central INS therapies can only be made by pre- and post-therapy comparisons of the nystagmus characteristics, specifically of the quality of the foveation periods within each cycle. If one is only interested in cosmetic improvements, diminution of the nystagmus amplitude is all that need be measured. However, if improvement of visual function is the primary goal of therapy, then measurement of the pre- and post-therapy foveation quality must be made, both in primary position and over a broad range of gaze angles. The use of the eXpanded Nystagmus Acuity Function (NAFX) on nystagmus data yields both an accurate measure of foveation quality and a prediction of maximum potential acuity for the patient's waveform. When used with the patient's measured, pre-therapy visual acuity, the NAFX demonstrates the amount of visual acuity loss that is due to sensory abnormalities, demonstrates the amount due to the nystagmus waveform, and estimates the measured post-therapy acuity for all values of improved NAFX and gaze angles measured. The ability to predict visual acuity improvement was not possible before the use of the NAFX. The failure to incorporate accurate measures of nystagmus waveform and foveation quality into their diagnostic evaluation continues to deprive patients of the best possible standard of care and results in mistaken diagnoses as well as inappropriate and, in some cases, unneeded multiple surgeries.
