[Solitary retinal astrocytic hamartoma simulating retinoblastoma].

Retinal astrocytic hamartoma and retinoblastoma may be very similar clinically and their differentiation in atypical cases can be difficult, even with the use of ultrasonography and computed tomography. In such cases, a close follow-up is recommended before enucleation. This paper reviews the case of a 18 month old girl who presented with a solitary retinal astrocytoma of the right eye, without any other physical or ocular disorder. The initial presentation simulated a retinoblastoma; nevertheless atypical patterns as yellow calcifications and the lack of tortuous and dilated feeding blood vessels were present. Ophthalmoscopic and ultrasound regular evaluation did not reveal any change after one year follow-up. Additional investigations performed in order to exclude tuberous sclerosis (neurological and dermatological examination, CT-scans) showed no other organ involvement, which ruled out a phakomatosis. The clinical appearance and course of astrocytic hamartomas, its differential diagnosis from other retinal tumors, especially retinoblastoma, and its association with tuberous sclerosis are discussed.

[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. Immunohistochemistry revealed an inflammatory pseudotumoral process. Both patients are recurrence-free 2 years follow-up. DISCUSSION: Inflammatory pseudotumors of the orbit, particularly those located in the lacrimal gland still raise unresolved questions concerning the pathogenesis, diagnosis and treatment. CONCLUSION: Lacrimal gland localizations of inflammatory pseudotumors must be recognized due to difficulties in diagnosis and therapeutic management.

[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.

[Value of ultrasonography in persistent hyperplastic primary vitreous body. Apropos of 4 cases].

The authors report 4 patients with complicated persistent hyperplastic primary vitreous. The complications observed are cataract (2 eyes) and retinal detachment (2 eyes). The affection is bilateral in two cases and unilateral in the two other cases. After a short embryologic vitreous recall, the authors present clinical and paraclinical aspects of the condition. The authors focus on the importance of echographic data.
