RESUMEN
Despite the most careful retinal detachment surgery saving the eye muscles and the fascial structures, an extraocular muscle imbalance may occur. This can be expected especially when for scleral buckling procedures large implants or exoplants were used, or had to be placed under a rectus muscle. In some cases, however, postoperative diplopia results from decompensation of preexisting heterophoria or congenital ocular motor imbalance. A clear-cut differential diagnosis to separate these entities is essential for therapeutic considerations.

A report rarely a case of superficial spreading melanoma of the conjunctiva bulbi in a 40-year-old woman. As this kind of tumor is very found at this site, the unusual localisation rendered the differential diagnosis more difficult and delayed the radical operative therapy. After orbitectomy the patient has been free of local metastatic deposits for two years. She is fully rehabilitated by a good epithetis. The course of diagnosis in our case illustrates the necessity of uniform application of the nomenclature of cutaneous forms of melanomas and naevi in ophthalmology.

THE "Fadenoperation" developed by Cüppers is described. With this, the arc of contact is changed with retension of the anatomical insertion. It is indicated when an innervational factor is to be influenced, especially by the treatment of an instable squint angle caused by nystagmus. A differentiation between a static and dynamic angle must be made. Only the static angle can be corrected by common recession and resection. The dynamic angle can be corrected by the "Fadenoperation" described by Cüppers. The difficulty in recognizing the nystagmus and determining the width of the static and dynamic angle is described in detail. Satisfying results were attained, following these criteria, shown by 19 (76%) of the operated convergent squinters with an instable angle.
