“…The echographic examination showed abnor mal optic nerves in 4 of 9 patients. Three pa tients showed a thickening of the optic nerve due to an increase of subarachnoidal fluid within the neural sheaths; this echographic pattern is pathognomonic for mild-moderate intracranial hypertension [7], In l patient, the increase in thickness was not always present. The occasional thickening observed in this patient can be related to the normal evolution of BIH that sometimes shows a spontaneous regression within months [9], The ophthalmodynamometric examina tion showed abnormal values in 4 of 9 pa tients.…”

A group of patients with empty sella syndrome (ESS) and visual field defect with or without visual loss has been examinated with standardized echography and ophthalmodynamometric examination. The optic nerve thickness has been evaluated with standardized echography; the pressure of the central retina artery has been evaluated with ophthalmodynamometric examination with or without compression on the external carotid. Our results point out two different pathogeneses in the ESS: vascular defects or irregular endocranial hypertension.

“…The presence of a normal optic nerve with standardised A scan rules out the presence of a primitive neoplastic tumour of this structure. 7 Ossification of the choroid is typical of the phthisical eye. The phthisical eye, because of increased thickness and folds of the choroid, shows a shadowing ofthe posterior orbital tissues.…”

A case of choroidal osteoma presenting in a 22-year-old girl is reported. The tumour, unilateral and in a juxtapapillary site, appeared markedly elevated on the retinal plane, not flat or slightly elevated as in previous reports.Visual acuity was not affected, and there was a complete absence of subjective symptoms. Echography, fluorangiography, computerised tomography, and visual field tests were performed. Echography is the best method for identifying and differentiating this lesion from a malignant tumour. Case report A 22 year-old-girl presented without any previous relevant medical history. The right eye was normal. In the left eye the visual acuity was 60/60 and the anterior segment normal. A fundus examination revealed a solid mass of approximately 6x 6 papillary diameters located in the juxtapapillary region of the lower nasal quadrant. The mass was elevated from the retinal plane by about 5 dioptres and had a yellowish white centre and pinkish yellow sloping edges (Fig 1). Standardised echography5 showed the lesion as a solid, raised subretinal mass with an extremely high reflectivity, observable even at the anterior surface of the lesion and shadowing the sclera and also the posterior orbital tissues6 (Fig 2). The echographic images of the lesion were of foreign body type, showing spikes of extremely high reflectivity from the retinal surface corresponding to the tumour site (Fig 3). In the remaining areas the thickness of the retina and choroid was normal; the optic nerve was also of normal diameter and reflectivity.Fluorescein angiography showed a pattern of irregular hyperfluorescence overlying the tumour and evidence of diffuse staining of the tumour surface during the later stages. Numerous capillaries on the surface ofthe choroidal osteoma were present in the early phase of the angiogram (Fig 4). CT showed a radiodense lesion adjacent to the left optic nerve head, at the posterior pole, of the same density as normal bone (Fig 5).When the patient was seen a year after the first observation, no variations of the mass were noted. DiscussionThe 5 dioptres elevation from the plane renders this case atypical. The clinical picture of this tumour -its location, unilaterality, its arising from a single focus, and the patient's age when it 700 on 11 May 2018 by guest. Protected by copyright.

“…All patients received a full neuro-ophthalmologic examination, and all ONSDs were performed by the same surgeon (B.K.F.). When necessary to confirm the presence of buried optic nerve drusen, B-scan echography was performed, along with the 30°test to assess the amount of perineural fluid (12). Before ONSD, all patients had documented evidence of progressive loss of visual acuity or visual field, or both.…”

To our knowledge, this review represents the largest series of patients who have undergone ONSD for any indication. Our data are consistent with current literature supporting ONSD as a safe and effective procedure for IIH. Other indications for ONSD, such as progressive visual field loss associated with OND, warrant further study. Regardless of the indication, complications following ONSD with the technique described in this report are infrequent.
