Hydatid cyst: unusual cause of unilateral exophthalmos.

Intraorbital hydatid cysts are encountered unusually on neurosurgical services. Recently, 3 patients with intraorbital hydatid cysts have been studied by the Neurosurgical Service of C. S. "La Paz." In two of them, a computed tomography (CT) scan was performed; we think that these are the first cases of this type to be studied with CT scans. In each case, the CT scan showed a circular mass with a density similar to that of the eye. Frequency, localization, symptomatology, and neuroradiological aspects of intraorbital hydatid cysts are described. The different surgical approaches also are discussed.

[Is treatment with corticotherapy or radiotherapy effective for involvement of ocular motility and for reduction of exophthalmos in Basedow's disease?].

It is acknowledged that high-dose corticotherapy, radiotherapy, or surgical decompression of the orbit are often efficient in dysthyroid optic neuropathy. Corticotherapy and radiotherapy are also given to patients with dysfunction of eye-muscle motility and/or proptosis in the absence of visual loss. The latter indication has been retrospectively evaluated in 13 patients. The limited character of our series is partially explainable by strict inclusion criteria (objective evaluation of muscle dysfunction and proptosis). We failed to demonstrate any significant functional improvement after oral corticotherapy and/or radiotherapy. It thus appears that our study sheds doubt on the actual efficacy of these treatments in patients presenting with not very evolutive involvement of eye-muscle motility. A larger study aimed at comparing the benefits and drawbacks of these treatments is consequently to be encouraged.

[The current role of radiotherapy in immunogenic exophthalmos].

In this study, the value of radiation therapy was investigated in 41 patients with Graves' ophthalmopathy treated with orbital irradiation at the Radiotherapy Department of Mauriziano Hospital in Turin, 1986 through 1993. Our series consisted of 41 patients (32 women and 9 men), whose mean age was 53.6 years (range: 26-72 years). All patients had a high index of endocrine ophthalmopathy, based on the American Thyroid Association classification-NOSPECS classes III and IV. Irradiation was administered with two opposed convergent beams tilted posteriorly 5-10 degrees with 20 Gy/12 fractions/2 weeks. The total dose delivered to the lens was than 5%. The follow-up consisted of endocrinologic and ophthalmologic tests and, if possible, of pre/post-irradiation orbital US. A positive result was obtained in 31 patients, which was very good in 22 of them. Severe complications, i.e., 1 corneal ulceration and 3 cataracts, were observed in the patients with associated ocular conditions and were treated simultaneously with high-dose corticosteroids so that no direct and unquestionable correlation can be made between irradiation and complications. To conclude, our data show that radiation therapy can improve the signs and symptoms of Graves' disease, as many authors report.

[A new method for measuring exophthalmos. The slit lamp exophthalmometer].

We compared the most commonly used exophthalmometer according to Hertel (HE), which is criticized in the literature because of its low reliability, with the prototype of a new slitlamp exophthalmometer (SE). The apex of the eye and an index mark, which is in a fixed relation to the orbit, can be observed simultaneously, using a system of two mirrows. The advantages are a more accurate scale (up to 5/100 mm) and the independence of measurements. Exophthalmometry was performed in two experiments. First, we measured an artificial eye to determine the intra- and interobserver variation. The values of HE were 0.18 mm and 0.27 mm, respectively, those of SLE less than 0.08 mm. Second, we measured ten healthy volunteers to determine the interobserver variation. The value of SLE was significantly smaller (P < 0.01) than the value of HE. In conclusion, the SE is more reliable than the HE concerning the intra- and interobserver variation and can be recommended for research purposes as a useful alternative to the HE.

[Unilateral pseudotumoral exophthalmos in ethmoid-sphenoid-maxillary mucocele].

The authors present a case of ethmo-spheno-maxillary mucocele revealed by the appearance of a giant unilateral exophthalmia with an important decrease of visual acuity and spectacular regression of symptomatology after surgical excision. We must note the initial location near the tear ductus, the slow progression (12 years) with a false aspect of chronic dacryocystitis.
