Production of anterior segment ischemia.

Anterior segment ischemia changes can occur without detachment of any muscles. The most common cause of such ischemic changes of the anterior segment is the removal of too many rectus muscles in one operation. Twenty dog eyes and eight monkey eyes were subjected to the disinsertion and detachment of various combinations of extraocular muscles. They were sacrificed at intervals from 30 to 90 days. During the observation period, they were observed for gross and slit lamp changes. The enucleated eyes were studied microscopically for signs of ischemic and necrotic changes. Two patients who were studied, observed, and treated for anterior segment ischemia following muscle surgery are described. The changes which occur after muscle surgery are extensive and include corneal edema, cataract, chemosis, corneal changes, decreases in intraocular pressure, decreases in outflow or glaucoma and frank necrosis. The variables which lead to this reaction is described in detail. Also, some unanswered queries, such as the duration of the reaction and the time interval of the reaction after multiple muscle surgeries, are discussed.

Medical management of accommodative esotropia.

Cycloplegic drugs are the principal medications used in the diagnosis of accommodative esotropia. The same cycloplegics can be used as a "medical patch" in the treatment of amblyopia. Miotics may be as good as glasses in controlling accommodative esotropia but are almost never better. The response to miotics does not rule out the presence of accommodative esotropia. Miotics also may be used as a supplementary agent to glasses, bifocals, or surgery in the treatment of esotropia. The most widely used miotics today include phospholine iodide and DFP with iris cysts being the major local side effect in the eye with the use of miotics in children. Miotics and other drugs are valuable tools in the treatment of accommodative esotropia; however, the use must be correlated with other tools, including surgery, patching, glasses, and orthoptic exercises.

True charity and professional life: a patient advocacy program.

The Patient Advocacy Program, built on an already existing, sympathetic hospital staff, has placed added emphasis on the physician-patient relationship which recently has been obscured by increasing technology, mechanization, and third party process. Furthermore, the Patient Advocacy Program stresses that the patient is the most important reason for the focus of the physician and staff. We have tried to exhibit not only true professionalism, but also true charity, by giving more than is expected and in return receiving an appreciative and satisfying response from patients, parents, and responsible parties.

Extraocular muscle transplantation.

1. The transplantation of extraocular homografts in dogs and humans has been described. 2. The extraocular muscle tissue transplanted remains viable, but loses its characteristics of muscle tissue during the period of the normal healing process following extraocular muscle surgery. 3. Autogenous homograft of extraocular muscle has an advantage over artificial synthetic material with the absence of extrusion and less reaction. 4. This is a clinically usable procedure today, especially in the amblyopic ehe with high deviation to accomplish an additional lengthening of one extraocular muscle, particularly if extraocular muscle surgery has previously been performed.
