General anesthesia is less utilized in ophthalmology. There are some criteria that lead to general anesthesia: patients with auditive debility, aged and senile patients, allergic patients, children and young patients, and subjects who totally refuse loco-regional procedures. General anesthesia utilizes as basic products: narcotic substances, analgesic substances, or neuroleptic substances utilized separately or associated, with posology adaptated to several factors: patients' pulse, physical statement, age, duration. The type of anesthetic substance depends also of specialist anesthetist experience.

Neovascular glaucoma is defined as an iris and/or anterior chamber angle neovascularization associated with increased intraocular presure. It is a secondary glaucoma most frequently determined by a severe retinal ischemia. ⋯ Vascular endothelial growth factor is an important and probably predominant agent in the pathogenesis of both intraocular neovascularization and neovascular glaucoma. The evolution of clinical and histopathological changes from predisposing conditions to the occurrence of rubeosis iridis as well as neovacular glaucoma is divided into four grades that is prerubeotic, preglaucomatous, open-angle and angle closure glaucoma stages.

Review Case Reports
[Paralysis of the oculomotor nerve caused by aneurysm--general facts and a case report].
One of the most frequent etiology of oculomotor nerve palsy are intracerebral aneurysms. Due to anatomical facts (its course and main relations with vascular structures of the brain) lesions of the oculomotor nerve often occur. In this paper there are presented essential issues concerning neuroanatomy of the III-rd cranial nerve pair main locations of the cerebral aneurysms in order to investigate the effect of nerve compression, clinical data regarding the palsy of the oculomotor nerve due to a cerebral aneurysm, the treatment and post surgery recovery followed by a clinical report.

Toxoplasma gondii is the most frequent cause of chorioretinitis in immunocompetent patients. This paper highlights the case of a 15 years old girl, an immunocompetent patient, with an active chorioretinal focus in the LE and a chorioretinal scar in the RE. Serologically, the IgG antiToxoplasma titre is increased, but the IgM antibodies are negative. It is the bilateral character of the lesions and the serology found that make this case special.
