Marcus Gunn Jaw-Winking Phenomenon: management and results of treatment in 19 patients.

From 1980-1995, 19 patients displaying the Marcus Gunn Phenomenon (MGP) were treated in the Department of Maxillofacial Surgery of the Jagiellonian University in Kraków, Poland. Sixteen patients were operated on according to the Neuhaus method, in one case bilaterally. In three patients, the upper eyelid, after partial transsection of the levator muscle, was suspended from the frontal muscle on autogenous temporal fascia strips.

[Changes observed in electrophysiological investigations in amblyopia and strabismus].

Purpose: The aim of the investigations was to state whether strabismic amblyopia and aniseiconia can be connected with disturbance of visual evoked potentials (VEP).

Material And Methods: VEP investigations in 28 children with amblyopia, aged from 4 to 12 years and in 16 healthy persons were performed. Analysis of amplitude and latency of the positive wave P1 and negative wave N2 in the healthy eye and in the amblyopic eye was done.

[Results of investigations of visual evoked potentials in the treatment of amblyopia].

Purpose: The aim of the study is to demonstrate the changes in visual evoked potentials (VEP) in treatment of amblyopia.

Material And Methods: Pattern reversal VEP of 28 children treated because of amblyopia and 16 healthy persons were analysed. Before treatment and after treatment the results of the interocular amplitude difference ratio and interocular latency difference ratio were compared with standards.

[Selected problems with ocular accommodation in children and youth].

This paper intends to present some accommodative disturbances which cause difficulties in reading and should be differentiated from dyslexia. The work describes the way of evaluation of accommodative convergence to accommodation rate (AC/A ratio). Clinical forms of two types of nonrefractive accommodative convergence excess connected with high AC/A ratio, namely hyperkinetic and hypoaccommodative, are presented.

[Principles and results of treatment in acquired paralysis of III, IV and VI nerves].

Between 1979-1994 120 patients with acquired paralysis of cranial nerves of ocular muscles were treated: 33 cases with paralysis of oculomotor nerve, 43 cases with paralysis of trochlear nerve, 44 cases with paralysis of abducens nerve. The majority of our patients were males (84-70.0%) aged 21-40 years (65-54.
