Having observed a very tight adhesion between the trochlea and the tendon of the obliquus superior bulbi muscle or an increase in tendon thickness posterior to the trochlea in operated patients, the author tried to correct this abnormality using partial trochleotomy and the lysis of the adhesions, followed by the application of Scott-Knapp sutures. The morphological basis of Brown's syndrome, consisting of an obstruction at the level of the trochlea, was demonstrated experimentally by means of an eye motion simulator.

The results are reported of our operative experience with 22 cases of external congenital ophthalmoplegia. The familiality, the muscular enzymes and isoenzymes, and often the skeletal electromyography have been studied, with the latter three being significantly altered in most cases. The main indication for surgery is the need to improve the anomalous position of the hyperextended neck. In the presence of inherent ptosis, this is achieved by suspending the upper eyelid from the frontalis muscle by using an autogenous fascia lata. A review of the previously published reports on eyebrow suspension leads one to conclude that autogenous fascia lata is the best material for this purpose.

The authors recorded pattern electroretinograms at different spatial frequencies in 16 patients affected with ocular hypertension. In 12 of these subjects the electroretinograms dropped in amplitude around 2 cycles/degree. The authors attributed this finding to ocular hypertension, hypothesizing ischemic damage at the head of the optic nerve with consequent fiber atrophy and degeneration of ganglion cells.
