[Pseudotumoral form of sclerochoroidal tuberculosis: a case report]. / Forme pseudotumorale de la tuberculose choroïdo-sclérale: à propos d'un cas.

The Authors report the US, CT and MR features of sclerochoroidal tuberculosis simulating a choroidal tumor in a 16 Year old female presenting with acute unilateral visual loss. Fundoscopic examination and fluorescein angiography showed a tumor at the posterior pole of the globe. CT and MRI showed the choroidal process and cerebral lesions suggestive of tuberculomas. The evolution was favorable with antituberculous treatment. Ocular tuberculosis is rare, especially the pseudotumoral form. It can simulate a choroidal tumor. Radiologists should be familiar with this appearance because the lesion is reversible with antituberculous treatment.

[Tumor of the lacrimal sac. Dangers of simple excision biopsy]. / Tumeur du sac lacrymal. Dangers de la biopsie exérèse simple.

Lacrimal sac tumors are relatively uncommon tumors which recur readily and have poor prognosis if adequate care is not provided early. We report here a case of lacrimal sac tumor in a 56-year-old patient with bilateral pseudophakia and an atypical chronic dacryocystisis aspect of the left eye. After clinical and paraclinical investigations, the patient underwent surgical excision of the tumor followed by external radiotherapy. During follow-up, the patient developed a local recurrence which required surgical removal and radiotherapy. Despite early and adapted management, the prognosis of this tumor remains poor.

[Severe toxic optic neuropathies caused by isoniazid. Apropos of 3 cases]. / Neuropathies optiques toxiques graves induites par l'isoniazide. A propos de trois cas.

Three cases of isoniazid-induced toxic optic neuropathy are reported. These severe forms of the disease lead in all cases to bilateral blindness despite drug withdrawal. The epidemiological, clinical and therapeutic aspects of the disease are discussed. Further emphasis is placed on the importance of systematic screening of patients at risk using regular ophthalmological examinations before and after treatment.

[Outcome of Behçet disease in ophthalmologic practice in Morocco]. / Devenir de la maladie de Behçet en milieu ophtalmologique marocain.

We treated 123 patients with Behçet's disease during a period of 10 years (1984-1993). The ocular lesions include uveal lesions especially the posterior lesions and vascular retinal. Uveitis was total in 72% of cases. Periphlebitis occurred in 51% of cases, vein occlusion in 10% of cases, macular oedema in 16% and papillary oedema in 10%. Clinical course and prognosis were studied. The functional prognosis is poor as such lesions may lead to blindness, particularly due to papillary oedema maculopathy. The treatment used is based on immunosuppressive and corticoid steroid drugs.
