This paper discusses two cases of superior oblique paresis, two cases of cyclic hypertropias, and ten cases of large angle esotropia with high myopia. The association with Graves' disease, the treatment, and favorable prognosis in all cases is presented.

Six members of a family--the mother, three daughters, and two sons--have a unique syndrome consisting of congenital external ophthalmoplegia, bilateral facial weakness, lingua scrotalis, progressive chorioretinal sclerosis, and an intellectual deficit. Bilateral ptosis and almost complete ophthalmoplegia were found in three of the family members, bilateral facial weakness in two, and Parinaud's syndrome and convergence paresis in one. Electromyographically, a lesion of the lower motor neurons--"nuclear ophthalmoplegia"--was found. Three members of the family had different stages of progressive chorioretinal sclerosis and two had myopia. All the family members had lingua scrotalis, and all of those who had ophthalmoplegia had low IQs. Electroretinographic reactions were subnormal or absent in patients with chorioretinal degeneration. It was concluded that an extensive abiotrophic process, genetically conditioned, was a possibility.

Description of interocular accommodative disparities about 3 cases of young patients, whose occupations require an excellent stereopsis in near vision. Is is a paresis, an asynergy or a constitutional asymmetry? In order to delimit this pathology, the accommodative power of each eye has been measured on a reference population including 100 subjects aged 20 to 35 years. The suitable correction of this anomaly, allows an exact compensation and the recovery of a normal functional comfort.

Loss of accommodation, transient myopia, or both, were complications following retinal cryotherapy in two eyes and after panretinal photocoagulation in six eyes (seven patients). A 17-year-old young man had these refractive difficulties one week after cryotherapy for retinal holes. His accommodative amplitude measured 1.0 D in the treated eye and 8.0 D in the untreated eye. One week later he received cryotherapy to the previously untreated eye, reducing that accommodative amplitude to 2.5 D. Accommodative paresis and transient myopia resolved without treatment within five weeks. Six other patients (six eyes, seven episodes) with an average age of 33 years demonstrated accommodative loss (40% to 92% decrease, average decrease 64%), transient myopia, or both, after panretinal photocoagulation for proliferative diabetic retinopathy. All patients recovered without treatment within six weeks (average, 22 days). All young patients should be made aware of this transient, but troublesome complication before treatment.

Clinical manifestations of chronic intoxication due to organophosphorus pesticide (OP) and treatment by prifinium bromide, an anticholinergic drug (Padrin), have been introduced. All patients showed oculopathy, mainly neuro-ophthalmological impairments such as: 1. optic neuropathy, 2. degeneration of the retina, 3. defective vertical smooth pursuit, 4. myopia; spasm or paresis of accommodation with or without corneal astigmatism "with the rule" and mild general neurological impairments. These manifestations were more severe among children than in adults, who were environmentally exposed mainly to 3% Malathion sprayed by helicopters several times a year for over 3-5 years. Presumed intake of Malathion for a given child is a far lower dosage than considered previously. Padrin (prifinium bromide) with vitamin B12, C, and E were effective in regressing oculopathy exposed environmentally to OP pesticides.

Necrotizing scleritis may occur following ocular surgery, most commonly after cataract extraction. This complication developed in a 60-year-old woman following strabismus surgery for a gaze palsy and sixth-nerve paresis following a stroke. Although an autoimmune process is present in many patients with necrotizing scleritis, none was detected in this patient. Inflammation was controlled with topical and systemic corticosteroids and ibuprofen. Good visual acuity was preserved, and improved ocular alignment was achieved. Transient myopia, not previously reported in necrotizing scleritis, was observed.

Diplopia is a frequent neuro-ophthalmologic symptom with diverse etiologies. This article describes elementary diagnostic tests and frequent causes of diplopia. Monocular diplopia persists when the other eye is closed and usually disappears when the patient looks through a pinhole. It is usually caused by errors in the optical media of the eye and has to be differentiated from spectacle-induced side effect and non-organic disorders. A sign of non-organic etiology is absence of change in image position when the head is tilted. Binocular diplopia disappears regardless of which eye is closed. Binocular diplopia occurs when the images of both eyes cannot be fused. The most frequent direct cause of diplopia is acquired strabismus. Knowledge of several specific types of strabismus enables efficient patient management. Congenital and decompensating strabismus like accommodative esotropia, pathophoria, strabismus surso- and deorsoadductorius, retraction syndrome, Brown's syndrome and esotropia in high myopia only need ophthalmologic treatment. Orbital injury, orbital tumor, ocular myositis, Graves orbitopathy and vascular disease usually require multidisciplinary management. Neurogenic paresis, superior oblique myokymia, ocular neuromyotonia, myasthenia, chronic progressive external ophthalmoplegia (CPEO), internuclear ophthalmoplegia (INO) and skew deviation require specific neurologic examination. Treatment of diplopia includes treatment of the fundamental disorder, monocular occlusion, prisms and strabismus surgery.

The rectus extraocular muscles (EOMs) and inferior oblique muscle have paths through the orbit constrained by connective tissue pulleys. These pulleys shift position during contraction and relaxation of the EOMs, dynamically changing the biomechanics of force transfer from the tendon onto the globe. The paths of the EOMs are tightly conserved in normal patients and disorders in the location and/or stability of the pulleys can create patterns of incomitant strabismus that may mimic oblique muscle dysfunction and cranial nerve paresis. Developmental disorders of pulley location can occur in conjunction with large, obvious abnormalities of orbital anatomy (e.g., craniosynostosis syndromes) or subtle, isolated abnormalities in the location of one or more pulleys. Acquired disorders of pulley location can be divided into four broad categories: Connective tissue disorders (e.g., Marfan syndrome), globe size disorders (e.g., high myopia), senile degeneration (e.g., sagging eye syndrome), and trauma (e.g., orbital fracture or postsurgical). Recognition of these disorders is important because abnormalities in pulley location and movement are often resistant to standard surgical approaches that involve strengthening or weakening the oblique muscles or changing the positions of the EOM insertions. Preoperative diagnosis is aided by: (1) Clinical history of predisposing risk factors, (2) observation of malpositioning of the medial canthus, lateral canthus, and globe, and (3) gaze-controlled orbital imaging using direct coronal slices. Finally, surgical correction frequently involves novel techniques that reposition and stabilize the pulley and posterior muscle belly within the orbit using permanent scleral sutures or silicone bands without changing the location of the muscle's insertion.
