[Finding of Strongyloides stercoralis infection, 25 years after leaving the endemic area, upon corticotherapy for ocular trauma]. / Découverte d'une infestation à Anguillule, 25 ans après retour de zone d'endémie, à l'occasion d'une corticothérapie pour traumatisme oculaire.

In the field of ophthalmology, indications for high-dose corticotherapy are various. This paper reports the case of a Caledonian man who presented with intestinal strongyloidiasis, discovered 25 years after he had left the endemic area. A checkup before corticotherapy for traumatic retina edema provided the diagnosis of the infection. The authors emphasize the importance of searching for Strongyloidiasis stercoralis larva before initiating corticotherapy, as it is the main treatment responsible for parasitic dissemination. The most severe form of strongyloidiasis, the disseminated form, has a high mortality rate: 70%-90%. The definitive diagnostic test is enhanced larva recovery, which should be proposed to every patient returning from endemic area, people with precarious hygiene or with high eosinophilia or intestinal symptoms of chronic infection. Delay in diagnosing strongyloidiasis frequently results in death, despite vigorous treatment.

[Conjunctival biopsy: a useful procedure for the diagnosis of sarcoidosis]. / Biopsie conjonctivale: une aide précieuse pour le diagnostic de sarcoïdose.

PURPOSE: To highlight the advantages of conjunctival biopsy in order to confirm the diagnosis of sarcoidosis. CASE REPORT: A 78-year-old woman presented with unilateral vitreitis. The examination of the conjunctive of right and left eyes revealed multiple, translucent, pale yellow nodules the size of millet grains located in the lower fornix. The diagnosis of sarcoidosis was suspected by an increased level of angiotensin-converting enzyme and bilateral hilar lymphadenopathies. A biopsy from conjunctival nodules showed noncaseating epithelioid and gigantocellular granulomas, confirming the diagnosis of sarcoidosis. CONCLUSION: Although underused, conjunctival biopsy seems to be both a safe and effective tool in the diagnosis of sarcoidosis.

[Sebaceous tumors of the eyelids in a patient with Muir-Torre syndrome]. / Tumeurs palpébrales à différenciation sébacée dans le cadre d'un syndrome de Muir-Torre.

Muir-Torre syndrome is an autosomal dominant hereditary condition predisposing to cancer. It is characterized by cutaneous tumors (such as sebaceous adenomas, epitheliomas, or carcinoma, and/or keratoacanthomas) and internal malignancies. A 47-year-old male patient with cancer antecedents consulted for two tumors of the eyelid. Histological study of the exeresis biopsies of the eyelid lesions showed a sebaceous adenoma and an epidermoid carcinoma with sebaceous differentiation. With the suspicion of Muir-Torre syndrome, a genetic consultation was requested. The geneticist found a mutation of the MSH2 gene, which was not classified as pathological. Cancer screening was begun for the patient and his descendants. The clinical outcome was death from urothelial carcinoma. Eyelid sebaceous tumors require complete medical check-up in search of carcinoma. Demonstrating Muir-Torre syndrome allows the medical team to propose early cutaneous and visceral carcinoma screening for patients, their collaterals, and their descendants.

Subretinal electrode implantation in the P23H rat for chronic stimulations.

BACKGROUND: In age related macular degeneration and inherited dystrophies, preservation of retinal ganglion cells has been demonstrated. This finding has led to the development of various models of subretinal or epiretinal implant in order to restore vision. This study addresses the development of a polyimide subretinal electrode platform in the dystrophic P23H rat in vivo. METHODS: A technique was developed for implanting a subretinal electrode into the subretinal space and stabilising the distal extremity of the cabling on the rat cranium in order to allow future electrical stimulations of the retina. RESULTS: In vivo imaging of the retina with the scanning laser ophthalmoscope demonstrated reabsorption of the surgically induced retinal detachment and the absence of major tissue reactions. These in vivo observations were confirmed by retinal histology. The extraocular fixation system on the rat cranium was effective in stabilising the distal connector for in vivo stimulation. CONCLUSION: This study demonstrates that a retinal implant can be introduced into the subretinal space of a dystrophic rat with a stable external connection for repeatable electrical measurements and stimulation. This in vivo model should therefore allow us to evaluate the safety and efficacy of electrical stimulations on dystrophic retina.

[Cystic fibrosis and uveitis in childhood and multiple sclerosis at adulthood]. / Mucoviscidose, uvéite infantile et sclérose en plaques à l'âge adulte.

We report the case of a patient with cystic fibrosis who suffered severe bilateral uveitis, with hypopyon, retinal vasculitis, and polyarthritis when he was 6 years old. No etiology could be found. Multiple sclerosis began when he was 22 years old. This panuveitis was clinically very different from the uveitis usually associated with multiple sclerosis. Polyarthritis and skin vasculitis have been reported in the course of cystic fibrosis, but no uveitis nor retinal vasculitis have been described. This raises the question of the role of multiple sclerosis and cystic fibrosis in the pathogenesis of this case of uveitis.

[An atypical case of malignant hypertensive retinopathy in a young child]. / Présentation d'un cas atypique de rétinopathie hypertensive maligne chez une fillette.

Stage IV hypertensive retinopathies in children have been described, but their incidence appears to be rare. Most etiologies are nephropathies. The authors present a clinical case of malignant high blood pressure in a young girl whose ophthalmological tests detected an unusual nephropathy, the Ask-Upmark kidney, illustrating the importance of determining high blood pressure chronicity and using Kirkendall's classification. Systematic fluorescein angiography and NMR on atypical subjects prevents the diagnosis of Leber neuroretinis, the main differential diagnosis. Early treatment of high blood pressure can avoid complications such as macular exudes.

[Fibrinolysis in the treatment of the amaurosis fugax: a case report]. / Fibrinolyse dans le traitement de l'amaurosis fugax. A propos d'un cas.

The authors report a case of amaurosis fugax treated first by systemic fibrinolysis and then by antiplatelet treatment. A 47-year-old suffering from transient amaurosis due to recurrent occlusion of retinal arterial branches improved after treatment and showed no recurrence. This protocol appears effective in cases of probable embolus in a young patient with no contraindications and when flow is not reestablished (amaurosis fugax), or when the required 6-hour time delay is respected.

[Post-traumatic exophthalmos caused by a subperiosteal hematoma of the orbit]. / Exophtalmie post-traumatique due à un hématome subpériosté de l'orbite.

We report a case of a 27-year-old man who developed major exophthalmos associated with ophthalmoplegia occurring 48 hours after head trauma. CT scan showed an orbital roof fracture and a subperiosteal hematoma. Surgical evacuation of the hematoma and reconstruction of the orbital roof was performed via a frontal craniotomy. Two months later, the ophthalmologic examination was normal. We stress the importance of early diagnosis and prompt surgical treatment in such an unusual complication of head trauma.
