A scoring method for Hess charts.

A new scoring system for Hess charts is described. Scores for both horizontal and vertical deviations are calculated from the displacement of individual points on the Hess chart, using weighting factors for the centre, inner and outer zones. The scoring system was validated in a group of 24 patients undergoing surgery for paralytic or restrictive strabismus. Subjective scores were obtained from patients both before and after corrective surgery, and corresponding Hess charts were scored using the new system. There was a good correlation between the changes in subjective and objective score. Our scoring system has applications in both research and clinical practice, allowing objective analysis of changes in muscle balance in a variety of motility disorders.

Management of dysthyroid eye disease.

Once the diagnosis of thyroid eye disease has been made the doctor's problems begin because the management is long term with a condition that has many ramifications over a period of years. Short-term heroics to save vision by use of high-dose systemic steroids, orbital decompression or radiotherapy may have to be followed by control of diplopia by muscle surgery and prisms. Lid retraction, both upper and lower, may merit surgery, and even those patients who have come to terms with their facial appearance may still complain of lacrimation, irritation and grittiness. The advantages of a thyroid clinic, run jointly by a physician and an ophthalmologist, are presented and the patient is helped to live with this distressing condition.

The surgical treatment of traumatic Brown syndrome.

We present the results of surgical treatment in 13 patients who attended Moorfields Eye Hospital with traumatic Brown syndrome between 1975 and 1990. The average age was 34 years (range, 18 to 46 years), and in 12 cases the cause was a road traffic accident. Diplopia was the indication for surgery in all cases. Most patients had two surgical procedures; but in two patients, three were required. The outcome was assessed both subjectively and objectively. Objective assessment was by analysis of the preoperative and postoperative fields of binocular single vision and Hess charts which were available for 11 patients. The Hess charts were analyzed using a new scoring system. At final follow up, subjective improvement had occurred in 7 patients, 3 patients reported no improvement, and 3 patients thought their symptoms were worse. The field of binocular single vision improved in 8 patients and was worse in 3 patients. The Hess chart improved in 8 patients and was worse in 3 patients. The management of this difficult condition is discussed.
