[Diploptics - brand-new system of concomitant squint treatment (author's transl)].

The present paper exposes the shortcomings of orthoptics and proposes an original system of concomitant squint treatment named diploptics. This system is based on the new conception of the role of bifixation in the physiology and pathology of binocular vision. The major principle of diploptics is to induce diplopia under natural conductions and further to "enliven" or develope the ability to overcome it with the help of the optomotor fusion reflex and thus to recover the auto-control mechanism of bifixation - the basis of the normal binocular vision. To realize this principle a number of methods are suggested. A trial of these produced hopeful results.

The management of fractures of the zygoma.

A series of cases of zygomatic fractures was studied to see if a change to a more extensive surgical intervention was justified. The surgical anatomy of the cheekbone complex was studied and certain protective features which determine the pattern of fracture were noted; treatment which takes account of these facts was suggested. Some observations are made on diplopia and enophthalmos and a plea is made for caution in accepting the concept of the "blowout" fracture.

[An unusual case of focal symptomatology, monoparalysis of the abducent nerve and vertebrobasilar ectasia].

Ectasia of the basilar artery is a well-defined form with a complicated clinical symptomatology. Angiography has made it possible to show that its pathogenesis springs from marked changes in the diameter and length of the artery. A case is presented in which the usual array of symptoms was replaced by homonymous diplopia only. It showed that CT can on its own provide information both for diagnosis of the specific lesion, and for assessment of changes in the bone structures, the cerebral parenchima, and the ventricular system.

Pigmented corneal implants: a surgical treatment for iridectomy related optical complications.

Initial evaluation in rabbits demonstrates that corneal implants made from prolene and nylon sutures flattened into strips appear promising as a means of covering diplopia or glare-inducing iridectomies. Two-month follow-up studies showed the implants to be well tolerated in the corneal stroma. Results of the studies suggest that black prolene films of 50 to 70 micrometers in thickness, contoured to follow the corneal curvature, would be the ideal configuration for such implants.

[On the binocular function after surgery for detached retina (author's transl)].

Oout of 380 patients operated on because of retinal detachments we have analyzed 106 unselected cases as to their binocular results. The check-up reveals that only 3% of the patients complained of diplopia. After a general analysis of the Custodis-procedure in retinal detachment operations the possible reasons for the stated binocular results are discussed.

Assessment and management of bilateral superior oblique pareses.

31 patients with bilateral fourth nerve palsies are considered in this paper, 25 of the cases being traumatic in origin. Quantitative estimation of the torsional defect is carried out, using special synoptophore slides and a modification of the Lees' screen technique. Inability to prove the patient's retention of fusion in the presence of torsion is discussed. Although many of the traumatic cases had been rendered unconscious for varying periods of time up to several weeks by the initial injury with the known risk of losing fusion, sixteen out of seventeen patients undergoing surgery for their diplopia had postoperative evidence of binocular single vision.

Isolated bilateral abducens palsy.

This case illustrates the sudden onset and gradual regression of abducens palsy following an isolated brainstem infarct secondary to moderate to marked hypertension. This case also demonstrates that patients presenting with sudden diplopia need to be referred to internal medicine and/or neurology for further documentation of the etiology of this condition.

Dehiscence of lateral rectus muscle following intrascleral buckling procedure.

A 58-year-old woman underwent two operations within a week for repair of a rhegmatogenous retinal detachment in her left eye. The procedure consisted of the placement of an intrascleral buckle between the lateral and inferior rectus muscles and extending as explants under these two muscles. The ocular muscles were not disinserted as part of the surgery. Three and a half months postoperatively the patient had diplopia, marked left esotropia, and exposure of the buckle temporally. When the silicone implant was removed, the lateral rectus muscle was found to have spontaneously disinserted and to have reattached to the globe 9 mm posterior to its normal insertion.

Orbital leiomyoma accompanied by orbital pseudotumor.

We examined a 53-year-old man who had diplopia and proptosis of the right eye. Computed axial tomography showed a mass extending from the retrobulbar space to the apex and the lower portion of the right orbit. The tumor removed by the first operation from the retrobulbar space was diagnosed as leiomyoma. The mass palpated through the tissues of the lower right eyelid in the initial examination enlarged 7 months after the first operation. The tumor specimen subsequently obtained from this portion histologically revealed inflammatory pseudotumor. Therefore it was concluded that this patient had a leiomyoma accompanied by an inflammatory pseudotumor ipsilaterally.

Isolated paresis of the inferior oblique.

Four cases of isolated superior oblique paresis are presented. The usual course of events was that of a gradually increasing diplopia and head tilt. All patients fulfilled the three-step test criteria, with a hypertropia that increased on side gaze to the ipsilateral side and on head tilt to the side opposite that of the paretic muscle. All patients were treated with a superior rectus recession. Three patients had their hypertropia reduced to between zero and 2 diopters. One patient needed, in addition to his superior rectus recession, an inferior rectus resection to eliminate the hypertropia. Vertical rectus surgery presents an alternative to superior oblique muscle tenotomy in treating inferior oblique paresis.

Bilateral abducens nerve palsies from clivus chordoma.

An 87-year-old male complaining of horizontal diplopia of five months duration was found to have bilateral abducens nerve palsies. The remainder of the neurologic examination was unremarkable, but neuroradiologic investigation disclosed a lesion involving the sella and sphenoid sinus, with erosion of the upper aspect of the clivus. A large chordoma was found at trans-sphenoidal surgery. This presentation is unique in that the chordoma produced bilateral sixth-nerve palsies with no other neurologic defects.

[New viewpoints on the pathogenesis and the treatment of strabismus. 3rd part: management of strabismus (author's transl)].

The major complications of our surgery such as the duction limitations, the postoperative diplopia, the vicious cicatrices and the modifications of the palpebral fissure are considered in this article. The cause, diagnosis and treatment are discussed. In the conclusions the value of our two keys is commented on, the importance of our maximal and atraumatic surgery is stressed and the problem of delayed over-corrections is mentioned.

[The mechanism of inhibition of binocular vision in convergent strabismus (author's transl)].

The mechanism of inhibition of binocular vision (at a cortical level in the Pavlovian sense) in convergent strabismus is described. The study concerns both those patients whith no amblyopia and those whose amblyopia has been cured. Part one of the article describe the clinical characteristics of this cortical inhibition as shown by the polarised light stereoscopic projector. Some basic concepts with this therapeutic application are described in part two. In this paper the author suggests a relationships between the severity of inhibition of binocularity and the degree of disturbance in spatial localisation. The greater the inhibition at a cortical level, the more disturbed is the localisation of objects in space in binocular vision. The treatment of inhibition must include precipitating causes that is to say the disturbed binocular relationships of abnormal retinal correspondence and is complete when cortical inhibition and abnormal retinal correspondence has been completely rectified. On the other hand there are occasions when it is not possible to eliminate abnormal retinal correspondence, this is especially true in older patients, and under this circumstances, it is better to accept inhibition of binocular function than to have diplopia.

[Horton's disease: ophthalmological and neurological complication].

We report the case of a 74-year-old women admitted to the hospital because of rapidly developing diplopia. The admission anamnesis revealed fronto-temporal headaches and pain in the maxilla for three days. A cerebral cT scan was normal, and a corticosteroid therapy was initiated. Diagnosis of Horton's syndrome was confirmed by the good response to treatment and by biopsy of the temporal artery. Different ocular and neurologic complications of Horton's disease, their clinical appearances and therapeutic measures are discussed by the authors.

Wildervanck's syndrome presenting as hemiparesthesia.

A 41-year-old male presented with recent-onset left hemiparesthesia, described as a "tingling numbness" of the upper extremity, torso, and face. History revealed a lifelong horizontal diplopia, neck stiffness, and left-sided hearing loss for 5 months. Examination revealed an ocular exam consistent with Duane's retraction syndrome, clinical and radiographic evidence of congenital fusion of C2 and C3 demonstrative of the Klippel-Feil anomaly, and a sensorineural hearing loss confirmed by audiometry. The diagnosis of Wildervanck's syndrome was made based on this classic triad of findings. A thorough evaluation has not yielded an objective explanation for the episodic hemiparesthesia. We present a patient exhibiting the classic triad of Wildervanck's syndrome, whose presentation is unique because hemiparesthesia has not previously been reported in association with this rare syndrome.

[Surgical complications in accommodative esotropia].

The most important causes of surgical failure of accommodative strabismus are discussed and treatment is proposed. Limitations of duction are the most frequent causes and are to be carefully searched for. Postoperative diplopia is most often transitory and will be treated if it causes an obstacle to fusion. The prevention of surgical complications results in the long experience in motility examination and the system of combined horizontal and cyclovertical surgery.

Ocular motility defects in patients with the Krupin valve implant.

To determine the prevalence of ocular motility defects following placement of a Krupin valve with disk and adjunctive mitomycin-C in glaucoma patients, a retrospective case series of all patients receiving a Krupin valve with disk and intraoperative mitomycin-C in a university-based referral practice was conducted. Each of the seven consecutive patients undergoing placement of a Krupin valve with disk in one eye because of uncontrolled glaucoma, developed significant primary position heterotropia or limitation of ocular rotations. One patient had significant postoperative diplopia. We conclude that the Krupin valve with disk used with intraoperative mitomycin-C can be associated with the development of ocular motility defects. The limitation of rotations appears to relate to the combined mechanisms of implant and cyst bulk and the displacement of the oculorotary muscles by the encapsulating cyst.
