[Cataract surgery in an eye with intraocular tumor].

This case present the consequences of performing the cataract surgery on an eye with intraocular tumor, pointing the importance of a detailed and complete examination, even for the benign and easy to diagnostic diseases.

[Biomechanical stress in glaucoma--cause and effect].

Unlabelled: Glaucoma is a neurodegenerative disease with multifactor causes which is characterized by acute loss of ganglion cells. Many mechanisms are involved in this disease but they are incomplete elucidated. Biomechanical stress generate changes to lamina cribrosa which determine ganglion cells death.

[Hepatic actinomycosis--pseudotumoral form].

Hepatic actinomycosis is a pretty rare anatomo-clinical entity that often induces a wrong pre-operative diagnosis. By presenting a case of hepatic actinomycosis, apparently primitive and diagnosed pre-operatively as a neoplastic lesion, the authors discuss the diagnosis and treatment of this disease, mentioning that in the solid, tumoral forms, the hepatic resection is necessary. The authors consider that the post-operative addition of antibiotherapy (mega doses of penicillin) is useful for the eradication of inflammatory residual hepatic parenchyma as well as for the cicatrisation of the parietal fistulae.

[Neuroprotection with carotenoids in glaucoma].

Purpose: The aim of the paper was to assess the place of the natural carotenoids (lutein, zeaxanthin) in glaucoma optic neuropathy.

Methods: For this purpose, we carried out an experimental and prospective study, during 3 months, on 8 laboratory animals (Guinea pigs), which we increased the IOP, in both eyes, by cautery of two episcleral vessels. The animals were divided into treatment in two groups: the group I (5 Guinea pigs) which we modified their usual diets by adding 2 cps/day of IcapsL (6 mg lutein/zeaxanthin) and the group II (3 Guinea pigs)--control group, without increasing the diet with lutein and zeaxanthin.
