[Oculo-orbital manifestations of paranasal sinus diseases].

PURPOSE: The paper is a study of the oculo-orbital affections established by the sinusal lesions. METHODS: The study is retrospective for five years and it is affected by the patients with ocular and orbital affections hospitalized in Ophthalmological Clinic. Were used the sheets of the patients and a collaboration with ORL Clinica, where the sinusal affections were surgical cured. RESULTS: The ocular lesions caused by the sinusal inflammations were: acute uveitis, orbital cellulitis, unilateral exophthalmia without obvious inflammatory signs. The oculo-orbital signs were missing with oculo/sinusal treatment. CONCLUSIONS: Without treatment, the inflammatory or tumoral affections of the paranasal sinus, established oculo-orbital complications and the patients request the first time the oculist. It is necessary a collaboration between the ORL--ist and the oculist physician for of these cases.

[Changes in the vascular wall in the conjunctiva of patients with diabetes mellitus].

Venous capillary wall in type II diabetic patients' conjunctiva was examined. The study was performed on conjunctiva fragments removed from diabetic patients during the operation of senile cataract. The fragments were fixed in Lillie's solution then studied by using optical microscopy with usual but histochemical stainings, too. Conjunctiva fragments removed from patients of the same age, being operated by senile cataract and one conjunctiva from ten years old patient were examined by using the same techniques as they could be compared. Computer determinations of the external and internal diameter of the same capillary in all three groups were performed. Venous capillary wall thickening by type IV collagen hyperproduction in all the aged patients was noted. This kind of thickening is more revealed in aged diabetic person. Type I-III collagen presence in the capillary wall of the diabetic patients was noted, too. The average value of the differential between the external and internal diameter was increased in the diabetic patients with diabetic retinopathy. Venous capillary wall thickening in the diabetic patients is due to the basal membrana both by means of the type IV collagen hyperproduction and presence of the I-III collagen, too.

[Hemorrhagic glaucoma].

The hemorrhagic glaucoma defines a clinical syndrome which recognizes as a frequent symptoms the hemorrhagic element, and from the morphopathological point of view the presence of some neoformation vessels at the level of the iris and camerular angle. 22 clinical observations of hemorrhagic glaucoma which appeared during one year are analyzed. It is shown that the new vessels appear as a reaction of the tissues hypoxemia and especially to alon of the oxygen pressure that determines the increase of the vessels. Also in the hemorrhagic glaucoma appears a deficiency of the venous reaction which determines a deficiency of the venous flow. The new vessels appear because of the hypoxemia and acid lactic accumulation only as the presence of a vital iridian tissue, because the new vessels do not appear in necrotic tissues.
