Recurrent hemangiopericytoma and brachytherapy

A 42-year-old woman had two recurrences following excision of a hemangiopericytoma of the left orbit. A third local excision was followed by postoperative brachytherapy (55 Gy in 100 hours). One year later there is no sign of recurrence and the side-effects are minimal.     

The effects of irradiation on the eye and optic nerve

Late effects of irradiation of the eye and optic nerve in 74 patients are reviewed. Time-dose analyses are performed for lacrimal apparatus, retinal, and optic nerve injuries. Management of radiation complications is discussed. Recommendations are made regarding radiation treatment techniques and methods of reducing the risk of late injury.     

Orbital volume in young and adult rabbits

Summary One hundred and ninety-nine postnatal volumetric determinations were made of orbits from 159 young and adult rabbits (64 New Zealand, 95 Dutch) by means either of linear measurements or of removable permanent elastic rubber base imprints. The volumes were calculated from the weights and specific gravities of the orbital imprints. Orbital volume in the New Zealand albino rabbits ranged from 0.7 ml at 14 days to 7.8 ml at 302 days of age. By about 180 days of age orbital volume had reached about 6.5 ml, near its maximum, and was about nine times the size at 14 days of age.Orbital volume in the Dutch rabbits ranged from 3.6 ml at 98 days to 5.8 ml at 540 days of age and were smaller than the New Zealand rabbit orbital volumes. By about 180 days the Dutch rabbit orbital volume had reached its maximum of about 5 ml and was about 25 percent larger than at 100 days of age. Values of orbital volume for the Dutch rabbits correlated noticeably with weight.

Orbital subperiotal hematoma associated with extradural hematoma: one case report

Subperiotal hematoma of the orbit associated with extradural hematoma has been rarely reported in the literature. We report a case of an 8-year-old girl who presented after traumatism, a subperiotal hematoma of the orbit with two extradural hematomas. During the first clinical examination realized while the patient was unconscious, left exophthalmia was found, but after conscious improvement, we discovered ophtalmoplegia and a grade I papilla edema. The CT scan showed two extradural hematomas and a left intraorbital hematoma. The intraorbital hematoma was drained by surgical way but the extradural hematomas were not surgical. The outcome has been marked by the neurological improvement and the oculomotricity recovering.     

The intranasal ostium after external dacryocystorhinostomy and the internal opening of the lacrimal canaliculi

The purpose of this paper was to evaluate the appearance and location of the healed intranasal ostium and the internal aperture of the common canaliculus after uncomplicated external dacryocystorhinostomy (DCR). In 21 patients who underwent uncomplicated external DCR, the distances between the lacrimal puncta and the internal aperture of the common canaliculus were measured during surgery. The measurements were taken with a 1 mm diameter Bowman probe graded in millimeters. These measurements were recorded and considered the landmarks for the spatial localization of the internal aperture of the canaliculus. After surgery, under endoscopic control, the same method was used to measure the distance between the lacrimal puncta and the internal ostium, which was defined as the aperture through which it was possible to visualize the very first protrusion of the probe into the nose. The intra- and post-operative measurements were compared. Endoscopic photos of the healed endonasal ostium were also taken. The photos showed that when DCR procedures were not complicated by scarring or mucosal adhesions, the lacrimal sac became a depression perfectly integrated within the nasal mucosa. The scar at the site of junction between the nasal and the lacrimal sac mucosa appeared as a large-diameter pearl-like colored frame that surrounded the depression. In the context of the depression a small aperture, which presented a diameter of around 2 mm, could be easily visualized. The spatial location of this aperture corresponded to the internal aperture of the common canaliculus (p < 0.05).
