摘要:

A review of 35 consecutive cases of tumors metastatic to the orbit revealed that the primary tumor site was breast in 18 cases (51%), prostate in 6 cases (17%), lung in 2 cases (6%), gastrointestinal tract in 2 cases (6%), kidney in 1 case (3%), cutaneous melanoma in 1 case (3%), contralateral choroidal melanoma in 1 case (3%), and unknown in 4 cases (11%). The most common presenting signs and symptoms included diplopia with noncomitant strabismus, proptosis, and a palpable mass. In nine cases (26%), the orbital metastasis was detected in patients with no prior history of cancer. The average patient survival after the diagnosis of orbital metastasis was 13 months. Orbital metastasis from lung carcinoma carried the worst prognosis, with an average survival time of only 4 months. A summary of the clinical features of these 35 cases and a review of the literature on orbital metastatic disease will be presented.

摘要:

We found medial entropion of the lower eyelid to be common following orbital decompression for dysthyroid ophthalmopathy. In our series significant postoperative medial entropion was noted in 14 of 69 patients, an incidence of 20%. Only four of these patients had entropion severe enough to require surgery (6%). Before orbital decompression, only one patient was found to have significant medial entropion (1.4%). Analysis of associated factors disclosed a positive relation between the amount of operative proptosis reduction and the degree of postoperative medial entropion. A strong correlation was also observed with the type of approach; transantral surgery was much more likely to be associated with significant post-operative medial entropion than was transconjunctival surgery. We suggest that the inferomedial displacement of the muscle cone that follows orbital decompression results in a force vector, transmitted through the lower eyelid retractors and capsulopalpebral ligament, that intorts the medial lower eyelid. Medial entropion in this setting often coexists with lower eyelid retraction, and if a “spacer” of sciera or ear cartilage is to be inserted into the lower eyelid, it should be carried into the medialmost portion of the eyelid to recess the posterior lamellae, including the medial retractors, and allow the eyelid margin to return to its normal anatomic position.

摘要:

A syndrome of the typical patient with a dacryolith in the lacrimal sac or nasolacrimal duct is described, based on review of 107 consecutive patients undergoing dacryocystorhinostomy (DCR) and 43 patients with a history of dacryocystitis. The incidence of dacryolithiasis was 14% of all patients having a DCR. The typical patient with a dacryolith was 45 years old, had a 4.8 year history of intermittent epiphora, had at least one episode of acute dacryocystitis, and could be irrigated with some fluid getting into the nasopharynx. Patients undergoing DCR with a history of acute dacryocystitis had a nine times higher likelihood of having a dacryolith than DCR patients without a history of acute dacryocystitis. DCR was curative in all 15 patients with a dacryolith.

摘要:

Syringomas are benign epithelial tumors of the sweat glands. The diffuse nature of these raised tumors makes surgical treatment difficult. Three patients with eyelid syringomas were successfully treated with CO2laser vaporization. CO: laser therapy appears to be a safe and effective mode of treatment for these benign superficial eyelid tumors.

摘要:

Hematic cyst is a rarely encountered orbital lesion consisting of encapsulated blood or blood breakdown products. The abnormality may be recognized by identifying the cystic structure by B-scan ultrasonography or computed tomography. Cysts located peripherally in the orbit tend to have histologie features suggesting hematoma formation. More centrally located orbital cysts are sometimes associated with vascular abnormalities. In other cases, the etiology is obscure, as in the case presented here. The visual prognosis is usually good, and associated systemic abnormalities are lacking.

摘要:

An 88-year-old woman presented with a longstanding superomedial cyst of the orbit complicated by recurrent acute infection. Despite a clinical picture typical for a sine-orbital mucocele, no sinus abnormality was demonstrated. Histopathologic examination revealed a respiratory epithelial lining similar to that of the paranasal sinuses. Possible pathogenetic mechanisms are discussed.

摘要:

A 73-year-old woman with a history of chronic lymphocytic leukemia had bilateral dacryocystorhinostomies for bilateral chronic dacryocystitis. The procedures were performed 7 months apart. Twenty-four months after the first dacryocys-torhinostomy on the left side, the patient developed a mass in the area of the left lacrimal sac causing epiphora. A repeat dacryocystorhinostomy revealed a lymphocytic infiltrate causing the left dacryostenosis. Thirty-three months after the right dacryocystorhinostomy, the patient developed a right dacryostenosis with epiphora and no mass. Pathology specimens obtained during a repeat dacryocystorhinostomy on the right side revealed a similar lymphocytic infiltrate. This case is an unusual presentation of solid lymphoma in a traumatized area in a patient with chronic lymphocytic leukemia.

摘要:

A case of congenital double lacrimal fistula is herein reported. Both fistulae were noted at the time of surgery to connect to the common canaliculus. To the best of our knowledge, this is the only case of a double fistula that has been reported.

摘要:

A case is presented in which a unilateral “orbital decompression” had been previously performed, down-fracturing the orbital floor and in-fracturing the medial orbital wall. Because of persistent bilateral exophthalmos, a four-wall orbital expansion was performed. Orbital volume determinations were made before and after the second procedure, making it possible to compare the effects of the two operations.
