Amblyopia in congenital ptosis.

This study evaluates the association between congenital ptosis and amblyopia. Amblyopia was detected in 7 of 36 (19%) patients with congenital ptosis. Two patients (6%) with amblyopia had no contributing factors other than the presence of congenital ptosis.

Growth of the internal and external eye in term and preterm infants.

Background: Better knowledge of the growth patterns of the external and internal eyes of neonates would permit more accurate diagnosis of disorders that affect ocular size such as infantile glaucoma and microphthalmos. Such disorders preferentially may affect certain parts of the internal eye but not other parts. No previous study statistically has evaluated internal ocular growth in preterm newborns.

The effect of anterior transposition of the inferior oblique muscle.

The effect of anterior transposition of the insertion of the inferior oblique muscle was compared with the results from conventional inferior oblique muscle recession in 50 patients. Even though both groups of patients had a similar degree of overaction preoperatively, postoperative inferior oblique muscle action was weaker (P < .01) and upgaze more limited P < .

Distance stereoacuity. Assessing control in intermittent exotropia.

Background: A patient's ability to control an intermittent exotropic deviation is usually assessed by subjective means such as observation of control in the office, questioning the patient and/or family about control at home, and reports of monocular eye closure in bright light. An objective method of assessing control has not been developed.

Purpose: The purposes of this study are to determine if distance stereoacuity was different in patients with intermittent exotropia than in normal subjects and to determine if distance stereoacuity could be used as a objective means of assessing control in intermittent exotropia.

Congenital double elevator palsy: vertical saccadic velocity utilizing the scleral search coil technique.

Four patients with congenital double elevator palsy were studied who had clinically brisk elevation of the affected eye from downgaze to the midline position of rest, but severely limited or absent elevation above primary position. Forced duction tests were negative and Bell's phenomenon was present preoperatively in all patients. To clarify why upgaze saccades clinically seemed intact below but not above midline, vertical saccadic velocities were measured using the scleral search coil technique.
