[Devic's neuro-optic myelitis and pregnancy].

Introduction: Devic's neuromyelitis optica associates optical neuritis that is either unilateral or bilateral and acute transversal myelopathy. This disease seldom occurs and is rarely associated with pregnancy.

Observation: We report the case of a young 20-year-old woman who was 8 weeks pregnant.

[Macular serous detachment revealing acute lymphoblastic leukemia].

Background: Leukemias are a group of malignant diseases caused by immature hematopoietic cells proliferating in the blood marrow. Some manifestations result from ocular-orbital involvement, which usually occurs through the central nervous system. Other manifestations stem from vasculopathy and/or hemorheologic disorders (anemia, thrombocytopenia, hyperviscosity).

[Inflammatory pseudotumor of the lacrimal gland. Apropos of 2 cases].

Background: Inflammatory pseudotumors of the orbit are relatively common accounting for 12 to 15% of all orbital diseases. Lacrimal gland location is exceptional.

Case Reports: We report 2 patients aged 30 and 25 years who underwent surgery for an isodense tumor of the lacrimal gland.

[Tumor of the lacrimal sac. Dangers of simple excision biopsy].

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.
