[Medulloepithelioma of the ciliary body. A case report].

Medulloepithelioma of the ciliary body is an uncommon intraocular tumor occurring during the first year of life. Malignant degeneration may occur. We report the case of a 4-year-old child who presented medulloepithelioma of the left eye disclosed by oesotropia at 2 years of age. Clinically, there was oesotropia, positive light perception and cataract with vascular membrane spreading to the nasal side of the irido-corneal angle. CT scan and ultrasound B revealed a ciliary body tumor involving the sclera and orbital fat. After exenteration, the pathology study reported malignant medulloepithelioma of the ciliary body with scleral extension. No local recurrence or metastasis has been observed at 8 months follow-up. We discuss the clinical, radiological and therapeutic features of this uncommon tumor.

[Epidemiology of orbital processes in children. 54 cases].

PURPOSE: The aim of this work was to study epidemiological aspect of orbital processes occurring in childhood. PATIENTS AND METHODS: Fifty-four cases of orbital processes treated between January 1990 and January 1997 were retrospectively reviewed. RESULTS: Mean patient age was 4.2 years (range 1 to 15), 36 were males and 18 were females. Proptosis was the first manifestation in 34 cases, other manifestations were low vision (8 cases), ocular pain (14 cases), inflammatory signs (11 cases), ocular palsy (14 cases). The first cause of these processes was secondary tumors, especially retinoblastoma (13 cases). Other causes were rhabdomyosarcoma (9 cases), orbital hydatic cyst (8 cases), inflammatory pseudotumors (7 cases), capillary hemanigoma (4 cases) chloroma (3 cases), glioma (1 case), lymphangioma (8 cases), and mucocele (1 case). DISCUSSION: We emphasize the particular epidemiological aspect of orbital processes in Moroccan children where retinoblastoma predominates and compare our findings with data in the literature.

[Retinal vasculitis].

PURPOSE: The purpose of this study is to determine aetiologies of vasculitis of retina in Morocco. MATERIAL AND METHODS: This is a retrospective study on 108 cases of vasculitis of retina admitted in the ophthalmology department, for a 5-year period (1987-1993). Our patients had a complete ophthalmological examination : fluorescine angiography, colour vision, general examination and biological study. RESULTS: Many aetiologies have been found, predominantly Behcet's disease. The neovascularization of retina which complicates the vasculitis was detected in 30 % of our patients. A laser photocoagulation was performed on these cases, sometimes a vitrectomy was necessary when a haemorrhage of vitreous body occurred, complicating the neo-vessels of retina. The therapeutics received by our patients was based on the corticotherapy. An immunosuppression treatment was prescribed in most cases of Behcet's disease and in severe vasculitis. Outcome after treatment has been satisfactory, but many patients relapse very frequently, mainly those with Behcet's disease. CONCLUSION: Causes of vascular retinitis are variable, most of them are due to Behcet's disease.

[Severe toxic optic neuropathies caused by isoniazid. Apropos of 3 cases].

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.
