Bilateral papillomacular retinal folds and posterior microphthalmus: new features of a recently established disease.

Clinical findings of a 2.5-year-old girl presenting with barely detectable horizontal nystagmus and high hypermetropia are described. Despite the normal appearing anterior segments, the child had posterior microphthalmus and bilateral papillomacular retinal folds, conforming to a recently described, rare congenital disease. The patient also had significant posterior pole excyclorotation and avascular zones at the extreme temporal periphery without ridge formation or neovascularization. These findings were not reported previously. Other remarkable features include mildly depressed photopic and scotopic electroretinogram amplitudes and a short axial length of the vitreous cavity compared to age-matched normals, measured by ultrasonography. The present case adds new elements to this relatively rare ocular developmental abnormality.

Management of traumatic luxation of the globe. A case report.

PURPOSE: To report the management of a patient who had LeFort type III fractures and traumatic luxation of the globe with avulsion of the optic nerve and all extraocular muscles except for the medial rectus. METHODS: Eight hours after the trauma, the detached and retracted superior and lateral recti muscles could be found and sutured to their original insertions. The inferior rectus could not be retrieved. RESULTS: Although the left eye had no light perception, most of its motility was restored resulting in an unblemished cosmesis. CONCLUSION: Avoiding primary enucleation helped to alleviate the psychological burden of the trauma on the patient. In case of the eventual development of phthisis bulbi, the patient will have a chance to be fitted with a prosthesis over his own eye with a resulting better motility.

Carotid-cavernous fistula following percutaneous trigeminal ganglion approach.

A case of carotid-cavernous fistula following percutaneous trigeminal ganglion approach is presented. The case was treated by a combination of trapping and embolisation of the carotid artery. Percutaneous approach to the trigeminal ganglion via the foramen ovale was described by Taptas (1911) and Hartel (1914). Since then this procedure has been used in large series, for the injection of alcohol (Harris, 1940), electrocoagulation (Kirschner, 1942) or the injection hot water (Jeager, 1957) to the trigeminal ganglion for the treatment of trigeminal neuralgia. In 1965 White and Sweet used the percutaneous trigeminal ganglion approach for the radio-frequency (R.F.) thermocoagulation of the trigeminal ganglion. This procedure is a simple and safe method. It has been used in large series in the treatment of trigeminal neuralgia. In our department we have performed 252 R.F. thermocoagulation of the gasserion ganglion in 228 patients since 1975. In 252 interventions using the percutaneous trigeminal ganglion approach, via the foramen ovale, we observed only one carotid-cavernous fistula following the procedure. This is the second report in the literature of a carotid-cavernous fistula following the percutaneous trigeminal ganglion approach.

Intracranial tuberculomas.

In this paper the clinical findings, operation results and histological diagnosis of eight patients with intracranial tuberculomas are described, which were admitted to the Neurosurgical Clinic of Ankara University, Faculty of Medicine, during the years 1967-1975, among the 1,015 histologically verified intracranial tumours. Our impression by reviewing previous papers on this matter is, that although tuberculomas are not so frequently seen as before, they still count as a certain percentage in Turkey.
