Malignant optic glioma in a 70-year-old patient.

In a 70-year-old man with glioma of the optic nerves and tracts, the initial symptom was a unilateral loss of vision that progressed rapidly and was followed by amaurosis of both eyes. All diagnostic radiological procedures were negative. Four months after the onset of the disease, the patient developed hemiplegia, became comatose, and died. Post-mortem examination revealed a glioblastoma multiforme of both optic nerves, chiasma, and optic tracts that extended posteriorly into the left thalamus and medial geniculate body. The tumoral thickening of the optic nerves was absent in the intracanalicular part, a finding that concurred with the normal radiological appearance of the optic foramen. Glioblastoma multiforme of the optic pathways should be included in the differential diagnosis of acute visual failure in elderly people, even though the final diagnosis may be possible only at postmortem examination.

Retinal red-free light photographs in two congenital conditions: a case of optic hypoplasia and a case of congenital hemianopia.

Two patients with congenital anomalies involving the optic pathways are described. The first case presented a unilateral hypoplastic optic nerve as well as an ipsilateral inferior conus and an elevated disc. The second case showed the features of homonymous hemianopia with sparing of the macula and decreased visual acuity on the side of the affected cerebral hemisphere. Red-free photographs were obtained in both cases. The importance of this old-new investigative tool in completing a neuro-ophthalmological study is stressed.

Spontaneous hyphema and vessel anomaly.

We describe a case of spontaneous hyphema, in which results of fluorescein angiography revealed that the condition was caused by anomalous iris vessels. A cavernous hemangloma of the ipsilateral orbit was discovered. We stress the importance of performing fluorescein angiography in all cases of spontaneous hyphema.

Prepapillary metastatic abscess in a case of subacute bacterial endocarditis.

The case of a 49-year-old woman is described in which the presenting symptom of subacute bacterial endocarditis was the rare condition of a prepapillary abscess. There was a rapid decrease in visual acuity in the patient's left eye 10 days after the onset of an influenza-like episode, and ophthalmological examination revealed a pus-containing formation covering the optic disc, star-figure exudates in the macula, and some retinal hemorrhages with white centers. These findings in a patient known to have old valvular stenosis indicated a diagnosis of subacute bacterial endocarditis which was confirmed by further investigation. Both forms of endogenous primary retinitis were present in the same eye, i.e. (1) acute suppurative metastatic retinitis in the form of a prepapillary abscess and (2) subacute focal retinitis with the characteristic Roth's spots. Intensive antibiotic treatment was instituted, and within one month the prepapillary abscess was resorbed, with a parallel improvement in the general condition of the patient.

Amaurosis fugax at downward gaze.

A 54-year-old man with a past history of hypertension, diabetes mellitus, hypercholesterolemia and two myocardial infarctions presented with repeated attacks of amaurosis fugax in the right eye. The fact that the amaurosis occurred only on downward gaze is sufficient evidence to exclude carotid atheromatous disease and to imply an orbital etiology.
