A 10-year-old girl with gradual-onset proptosis in her left eye was diagnosed with orbital alveolar soft-part sarcoma. The tumor and the contiguous medial rectus muscle in the left eye were excised and compensatory strabismus procedures were performed. Five years postoperatively, she has central binocular vision with no evidence of tumor recurrence.

Lymphatic malformation in the orbital cavity and surrounding region often causes disfigurement and visual problems. To better clarify the evolution and treatment of this condition, the authors studied a retrospective cohort of 42 consecutive patients seen between 1971 and 2003 and analyzed anatomic features, complications, and management. The ratio of female to male patients was 1:1. Most periorbital lymphatic malformations were noted at birth (59 percent), presenting as either unilateral swelling (60 percent) or a periorbital mass (24 percent). Sixty-two percent of lesions were on the left side. The ipsilateral cheek, temple, and forehead also were involved in 57 percent of patients. Twenty-two percent of lesions were intraconal, 30 percent were extraconal, and 48 percent were in both spaces. Forty-five percent of children had an associated cerebral developmental venous anomaly. Periorbital lymphatic malformation caused major morbidity; 52 percent of patients had intralesional bleeding and 26 percent of patients had a history of infection. Other common complications included intermittent swelling (76 percent), blepharoptosis (52 percent), proptosis (45 percent), pain (21 percent), amblyopia (33 percent), chemosis (19 percent), astigmatism (17 percent), and strabismus (7 percent). Ultimately, 40 percent of children had diminished vision and 7 percent became blind in the affected eye. Management of periorbital lymphatic malformation involved an interdisciplinary team that included an interventional radiologist, a craniofacial surgeon, and an ophthalmologist. The two therapeutic strategies were sclerotherapy (40 percent) and resection (57 percent); most patients required several interventions. A coronal approach was used for subtotal excision of fronto-temporal-orbital lymphatic malformation in 13 patients, whereas a tarsal incision was used for lesions isolated to the eyelid (n = 14). Ocular proptosis was temporarily managed by tarsorrhaphy (n = 9), but expansion of the bony orbit was needed to correct persistent proptosis (n = 8). Orbital exenteration was necessary in two patients.

Many phenotypic manifestations have been reported in cardiofaciocutaneous (CFC) syndrome, but none, to date, are pathognomonic or obligatory. Previous histopathological studies reported findings in skin and hair; no autopsy studies have been published. We report the clinical and autopsy findings of a 7-year-old boy with severe CFC syndrome and malnutrition of psychosocial origin. Manifestations of CFC, reported previously, included macrocephaly and macrosomia at birth; short stature; hypotonia; global developmental delays; dry, sparse thin curly hair; sparse eyebrows and eyelashes; dilated cerebral ventricles; high cranial vault; bitemporal constriction; supraorbital ridge hypoplasia; hypertelorism; ptosis; exophthalmos; depressed nasal bridge; anteverted nostrils; low-set, posteriorly-rotated, large, thick ears; decayed, dysplastic teeth; strabismus; hyperelastic skin; wrinkled palms; keratosis pilaris atrophicans faciei; ulerythema ophryogenes; hyperkeratosis; gastroesophageal reflux; and tracheobronchomalacia. Additional findings, not previously reported, include islet cell hyperplasia, lymphoid depletion, thymic atrophy and congenital hypertrophy of peripheral nerves with onion bulb formations. Although the islet cell hyperplasia, lymphoid depletion, and thymic atrophy are nonspecific findings that may be associated with either CFC or malnutrition, the onion bulb hypertrophy is specific for a demyelinating-remyelinating neuropathy. These findings implicate congenital peripheral neuropathy in the pathogenesis of the developmental delays, feeding difficulties, respiratory difficulties, ptosis and short stature in this case. Additional studies of other cases of CFC are needed.

A 6-year-old dog, a 4-year-old dog and three 7-week-old puppies were diagnosed with thiamine deficiency caused by feeding sulphite treated meat. The 6-year-old dog presented with a history of inappetence, weight loss and vomiting that rapidly progressed to signs of multifocal intracranial disease including mental dullness, paresis, seizures, spontaneous nystagmus and strabismus. Thiamine pyrophosphate effect was elevated at 58% and magnetic resonance imaging revealed bilaterally symmetrical hyperintensity of the caudate nucleus and rostral colliculi. The dog recovered with thiamine supplementation. The 4-year-old dog and three 7-week-old puppies also presented with rapidly progressive multifocal central nervous system signs including ataxia, paresis, increased muscle tone, seizures, nystagmus and exophthalmos. The 4-year-old dog made a rapid recovery with thiamine supplementation. Euthanasia and necropsy of a puppy revealed malacia of multiple brainstem nuclei and oedema of the cerebral cortex. These findings were consistent with thiamine deficiency.

Beare-Stevenson syndrome is a craniofacial syndrome consisting of a specific pattern of craniosynostosis resulting in a cloverleaf skull deformity and hydrocephalus, down-slanting palpebral fissures, proptosis, hypertelorism, strabismus, dysmorphic ears, choanal atresia, cleft palate, cutis gyratum, acanthosis nigricans, and abnormal genitalia. Its primary cause has been identified as a single amino acid substitution in fibroblast growth factor receptor 2. Of primary importance to the anesthesiologist are issues related to airway management resulting from midface hypoplasia, choanal atresia, and airway abnormalities (tracheal stenosis). Additional issues affecting airway management include associated cervical spine and foramen magnum abnormalities. The authors present their experience caring for a patient with Beare-Stevenson syndrome and discuss the anesthesia care of these patients.

A 14-year-old boy suffered right blunt orbital trauma. X-ray revealed a compressed fracture of the right ethmoidal sinuses. Three months after the trauma, progressive, painless right proptosis developed. Ocular examination revealed a severe proptosis and pronounced down displacement of the right globe without signs of orbital inflammation. A well-demarcated, extraconal right orbital cystic mass was seen on computerized tomography scan. The cyst contents were aspirated and found to contain echinococcal scolices and "hydatid sand." Hypertonic saline was injected and the cyst was excised. Progressive proptosis after blunt orbital trauma in patients from endemic areas should be suspected of being an orbital hydatid cyst.

The study aimed at finding out the clinicopathologic, ophthalmic and visual profiles, management and outcome of mucoceles of the paranasal sinuses in Nigerians. The study was a retrospective review of 20 cases of mucoceles who presented to the ENT clinic and referred to the eye clinic of the University College Hospital Ibadan, Nigeria. These included nine males and 11 females with a male:female ratio of approximately 1:1. Mucoceles commonly involved more than one sinus on the same side. The sinuses commonly involved were the frontoethmoidal sinuses, frontal sinus and maxillary sinuses. The preoperative visual acuity in 16 (80%) patients was 6/4-6/9, three (15%) had between 6/9-6/18, and one (5%) patient was CF ("count fingers") in the affected eyes. The majority (90%) of our patients presented with multiple ophthalmic features; however, proptosis was the most popular and ophthalmic presentation and occurred in 15 (75%) patients. Proptosis was nonaxial in all cases with inferior, lateral or inferolateral displacement. Degree of proptosis ranged from 1-20 mm. Other presentations were squint (leading to diplopia) observed in one (5%) patient and epiphora in another [one (5%)] patient. Poor vision appeared to be the main problem in one (5%) patient, while in another [one (5%)] patient, the affected eye was completely immobilized. One (5%) patient presented with orbital cellulitis. Common radiological findings included classical expansive appearance with loss of the normal scalloping appearance with dehiscence of the wall of the affected sinus as was observed in nine (45%) of our patients. All 20 patients had excision of mucoceles (frontoethmoidectomies). At surgery, 11 (55%) patients had a combination of dehiscence of medial and/or posterior walls, and/or floor of the orbit. Materials evacuated were mucopurulent in 15 (75%) cases, moldy in three (15%) and cheesy in two (10%). Nine (45%) patients had intact walls. Three (15%) patients developed orbital cellulitis as postoperative complication. Postoperatively, proptosis regressed spontaneously within one week of surgery in 17 (85%) patients. By six weeks, all the patients had a complete regression of proptosis and visual acuity returned to preoperative visual acuity level except the patient with preoperative visual acuity of CF. This patient later deteriorated and became NPL (no perception of light) in the affected eye. This was a peculiar case in that operative findings in this patient were suggestive of another coexisting pathology, which was later confirmed to be a non-Hodgkin's lymphoma of the orbit. After two months, only three (15%) reported back for follow-up. The study concluded that proptosis is a common feature of mucoceles of the paranasal sinuses and that visual affectation was rather uncommon. Also whilst mucopurulent materials formed the content of most mucoceles, surgical intervention caused proptosis to regress dramatically. However, due to the high default rate in our study, no categorical statement can be made about recurrence rate of these swellings.

The authors present the case of a child, 8 years old, victim of a car accident, suffering a cranio-cerebral trauma. The posttraumatic injuries were: bitemporal cranial fractures, LE VI nerve palsy with secondary convergent strabismus, left posttraumatic optic neuropathy with poor vision, right deafness, nasal bone fracture, left paramedian mandibular fracture. Four months later the child developed proptosis due to a high-flow carotid-cavernous fistula, on the site of the good eye, RE, which was clinically diagnosed and confirmed by the results of MRI, MRA and cerebral angiography. Considering the ophthalmologic and neurologic risks of this pathologic condition, the surgery was performed, using an external device (Silverstone clamp) with the purpose of progressive and adjustable control of the fistula thrombosis. The postoperative result was fistula thrombosis, preserving the visual acuity and visual field, with a residual hypertonia on the right eye. The peculiarity of the case consist in the small age of the patient and the severity of neuro-ophthalmologic lesions. The child will live for the rest of his life with a single well-seeing eye, whose function could be at risk at any moment, related to the posttraumatic vascular changes at the level of the right cavernous sinus.

A 56-year-old healthy man underwent left medial rectus recession and lateral rectus resection for esotropia. The next day he developed severe left periocular pain with decreased vision, an afferent pupillary defect, periorbital edema, limited ocular motility, and proptosis. Computed tomography showed fat stranding and less than 90 degrees of posterior globe tenting. Despite intravenous antibiotics to treat orbital cellulitis, and a lateral canthotomy and cantholysis to decompress the orbit, visual acuity worsened to no light perception. The patient underwent emergent orbital decompression including release of the superior and inferior septum and outfracturing of the orbital floor and medial wall; however, there was no recovery of vision. Blinding orbital cellulitis is a rare complication after strabismus surgery. Despite poor prognosis, prompt diagnosis and aggressive treatment may maximize visual potential.
