[Presumed ocular histoplasmosis syndrome].

Presumed ocular histoplasmosis syndrome is a macular hemorrhagic choroiditis of the young adult. The etiology of this syndrome is uncertain, but can be correlated with some positive reactions to histoplasmosis. The study was carried out on 12 patients, each of them was investigated by functional and objective ocular examinations, laboratory tests, fluorescein angiography and ultrasound examinations. The clinical signs of this syndrome of presumed ocular histoplasmosis were: macular focal lesions, subretinian hemorrhages, detachment of the retinal neurosensorial layer, presence of disseminated choroiditis scars and subretinian neovascularization. The correct evaluation of the choriocapillary perfusion is helpful to institute a proper therapy.

[Intraocular mass lesion--case report].

The authors present a case of a 27 years old patient, admitted in the Ophthalmological Department, presenting an intraocular mass lesion of the right eye, which consist of 2 different tumours of the eyeball (with different shape and location). The patient presents scleral staphiloma due to the intraocular tumours of the eye ball, the change of the shape and colour of the anterior aspect of the eye, loss of vision for two months. The complementary examinations for the diagnosis, that have been done (A Scan and Bscan, MRI of the eye ball) pointed to a possible choroidal hemangioma of the middle tunic of the eyeball. This diagnosis was confirmed by the histopathologic exam after surgery.

[Orbital varices].

The purpose of this study was to point out a case with orbital venous abnormalities at the left eye, associated with varices of the legs. The clinical picture of this case was: intermittent exophthalmos, venous malformations at the level of the lids and episclera, elevated ocular pressure. All this signs reveal an abnormality at the level of venous wall, indicating a constitutional weakness of the venous system. The case was investigated by imagistic methods: ultrasound examination, Doppler -ultrasound and magnetic resonance imaging. According to the facts offered by clinical and imagistic investigation this case can be included into the first type of orbital varices, associated with secondary glaucoma provoked by an elevated episcleral venous pressure.

[Clinical signs in vascular accidents of the retrochiasmatic pathways].

The purpose of this study was to determine the neuroophthalmologic signs which accompanies ischemic or hemorrhagic cerebral vascular accidents. This study was carried out on 110 patients, for three years. Most of the neuroophthalmologic signs, such as hemianopic deficits, have accompanied the ischemic vascular accidents. Hypertension was the most frequent cause of this vascular damages. The neuroophthalmologic signs were predominant at male, in comparison to female, in all the years studied. As the value of the etiological factory rise, rise also the incidence of the cerebral vascular damages accompanied with neuroophthalmologic signs.

[Imagery in secondary glaucomas diagnosis].

The purpose of this study was to present the actual performances of the imagistic techniques for the complete investigation of secondary glaucoma. For this aim there were selected patients from the Ophthalmologic Clinic Cluj-Napoca. They have been submitted to ultrasound investigations, fluorescein angiography and magnetic resonance imaging techniques. Ultrasound techniques: A-scan, B-scan and Doppler allow to track and discriminate the ocular and orbital diseases which can offer the bases of correct diagnosis in secondary glaucoma. The color Doppler assures a good visualization of neovascularization, tumoral vascularization, arterio-venous abnormalities. Magnetic resonance imaging completes the data obtained by ultrasound and fluorescein angiographique techniques. The imagistic techniques associated with the clinical features offer the bases of the diagnostic and proper therapy in secondary glaucoma.

[Arterial microcirculation in the optic chiasm, optic tracts and lateral geniculate bodies].

OBJECTIVES: The purpose of this study was to point out the microscopic vessels in the optic chiasm, optic tracts and lateral geniculate bodies. MATERIAL AND METHODS: This study was carried out on 20 brains, fixed in formaldehyde 10% and dissected under the surgical microscope. The material was summated to histological techniques on paraffin and performed on routine coloration. RESULTS: The lateral borders of the optic chiasm have more perforant branches as the median zone. The anterior and posterior segments of the optic tracts are rich in capillary vessels. The arteriolar branches penetrate into the lateral geniculate body on his inferior surface and borders. CONCLUSIONS: The knowledge of the arteriolar distribution in this segments of the optic pathways can explain the visual defects in some neuroophthalmologic syndromes.
