[Amblyopia treatment of unilateral and bilateral cataract with visual acuity result]. / Traitement de l'amblyopie des cataractes unilatérales et bilatérales avec résultats en termes d'acuité visuelle.

Treatment strategies of congenital cataract provide evidence of recent improvement in the visual prognosis. This trend is likely to be accounted for by a combination of improved management of amblyopia occurring in parallel with advances in surgical techniques, instrumentation, and materials. Compliance with occlusion is the factor most strongly associated with visual outcome: to support, to encourage, to comfort, to explain, to require (demand) to put in front of the responsibilities, here are the other missions of the therapist which are not less important than the surgical gesture. Progress, in this "educational" care of the visual function remains to make but the way is drawn.

[Effectiveness of interferon alpha in the treatment of uveitis macular edema refractory to corticosteroid and/or immunosuppressive treatment]. / Efficacité de l'interféron alpha dans le traitement des oedèmes maculaires uvéitiques réfractaires au traitement corticoïde et/ou immunosupresseur.

INTRODUCTION: Macular edema is always a major complication in intermediate and/or posterior uveitis. Some of these macular edemas are refractory to steroid and/or immunosuppressive drugs. Interferon, a validated treatment for Behçet disease, has antiproliferative and immunoregulative properties that may be very valuable in uveitic edema refractory to steroid and/or immunosuppressive agents. Recent studies have brought out the value of interferon-alpha by demonstrating its low blood rate in affected patients. OBSERVATIONS: We describe a series of six consecutive uveitic macular edema, secondary to two birdshot retinochoroidopathy, and four cases of idiopathic uveitis treated with interferon-alpha. Our small case series showed a 189.7+/-67 mum decrease in mapping and an improvement in visual acuity of 0.35+/-0.21 LogMAR. DISCUSSION: Other publications have shown a remarkable efficacy on macular edema and visual acuity in less than 1 month of treatment. Our small case series found the same results as the other studies, despite a less aggressive therapeutic regimen. However, we also observed some well-known side effects, in particular depression. CONCLUSION: In our series of six consecutive cases of uveitic macular edema refractory to steroid or immunosuppressive drugs, alpha-interferon provided highly advantageous anatomical and functional results. The treatment modality must be specified, but it seems that a shorter duration and lower posologies might be as effective and lead to a lower rate of complications than the regimen currently proposed in the literature.

[Orbital locations in Rosai-Dorfman disease: a series of three consecutive cases]. / Localisations orbitaires de la maladie de Rosai-Dorfman: série de trois cas consécutifs.

INTRODUCTION: Rosai-Dorfman disease (or sinus histiocytosis with massive lymphadenopathy) is a rare, benign entity, characterized by a histiocytic proliferative disorder that affects mainly the lymph node sinuses but also the lymphatics in extranodal manifestations. It affects mainly young men. The clinical syndrome consists of adenopathies, notably cervical, with fever and extranodal manifestations. Ophthalmological involvement is not frequent (10%), concerning above all the orbits, eyelids, and lacrimal glands, but cornea or uveal tissue can also be affected. Definitive diagnosis is anatomopathological, showing a histiocytic proliferation with lymphophagocytosis (emperipolesis) whose immunohistochemical analysis reveals CD68+ and PS100+. OBSERVATIONS: We describe a consecutive series of three cases seen in 2006 at the University Hospital of Nantes (France). One case presented an intraconical location with exophthalmos. The other two showed lacrimal fossa involvement. DISCUSSION: Our series, through the patients' mean age (61 years), symptom progression (from a few weeks to several years), clinical variability (several extranodal sites with no lymphadenopathy), and anatomopathological problems (especially extemporaneous analysis) shows the pathology's polymorphism as well as the diagnosis and therapeutic problems. CONCLUSION: A rare and unrecognized entity, Rosai-Dorfman disease can affect the entire ocular globe. Definitive diagnosis is only established by anatomopathological study. Although it is benign, ophthalmological involvement can cause severe damage, which requires efficacious treatment and a multidisciplinary approach.

[Familial primary pulmonary hypertension revealed by the association of bilateral chemosis, subacute myopia, and exophthalmos]. / Hypertension artérielle pulmonaire primitive familiale révélée par l'association bilatérale chémosis, myopisation et exophtalmie.

PURPOSE: To report a rare case of primary pulmonary hypertension (PPH) revealed by a relapsing chemosis, exophthalmos, and subacute myopia. PATIENTS AND METHODS: A 46-year-old woman presented with recurrent bouts of chemosis, exophthalmos, and subacute myopia. Her visual troubles were triggered by physical effort. She had a history of a longstanding high blood pressure that was noncompliant to all conventional hypotensive therapy. Automated refraction under cycloplegia showed recent myopia. At observation she had a bilateral, moderate chemosis. Hertel exophthalmometer measured a symmetric exophthalmos of 23 mm. Intraocular pressure was 20 mmHg OD and 24 mmHg OS. Eye fundus was strictly normal. RESULTS: Laboratory analysis showed no thyroid or inflammatory disease. HIV serology was negative as were antinuclear antibodies. Orbital CT confirmed the axial, symmetric exophthalmos. Echocardiogram brought out the diagnosis of PPH. Genetic studies by PCR localized the BMPR2 mutation that is characteristic of the familial type of PPH. Symptoms decreased under treatment. DISCUSSION: PPH is a rare disease caused by thickening of the arteriolar walls in the pulmonary bed, which results in a right-heart hypertension with venous stasis. Many authors have reported different posterior segment diseases secondary to PPH. However, anterior segment manifestations are extremely rare. These may be caused by a ciliary body congestion and retrobulbar vasodilatation. CONCLUSION: The association of chemosis, exophthalmos, and subacute myopia is unusual in PPH. We recommend keeping in mind the PPH as a differential diagnosis in those cases, especially in patients who suffer from high blood pressure.
