[Helicobacter pylori in central serous chorioretinopathy and diffuse retinal epitheliopathy. Results of the first prospective pilot study].

Purpose: Helicobacter pylori has been implicated in focal occlusive arterial diseases in young people. Central serous chorioretinopathy (CSC) and diffuse retinal epitheliopathy (DRE) being suspected vascular occlusive diseases of choriocapillaris, the purpose of this study was to determine the prevalence of H. pylori infection in patients with long-lasting (>6 months) CSC and/or DRE.

[Intraocular cysticercosis: a difficult diagnosis].

The authors describe a case of intraocular cysticercosis discovered in the ophthalmology department ef Edouard Herriot Hospital. With no biological signs, the diagnosis was made after vitrectomy because the visit was late in the course of the disorder, the patient lived in the mountains, and he had failed to mention a trip to the West Indies 3 months before. The symptomatology began with uveitis worsened in 10 days by greater inflammation in spite of successive corticosteroids, antibiotic, and antiviral therapy.

[Persistent hyperplastic primary vitreous syndrome in a girl with Aicardi syndrome].

Aicardi syndrome is characterized by infantile spasms, agenesis of the corpus callosum and chorioretinal lacunae. This disorder affects mostly females with early embryonic lethality in males. We present a case of persistent hyperplastic primary vitreous (PHPV) in association with Aicardi syndrome in a 2-year-old girl.

[Neovascular glaucoma diagnosed following carotid endarterectomy].

We report a case of bilateral asymptomatic rebeosis iridis related to a bilateral obstruction of the carotid arteries. The iridocorneal angles were closed by a neovascular membrane and intraocular pressures were normal within both eyes (normotensive neovascular glaucoma). After left carotid endarterectomy, the increased perfusion of the ciliary body and the increased secretion of aqueous humor resulted in a sudden bilateral ocular hypertension.

Posterior chamber intraocular lens dislocation with the bag.

We report a rare case of a 46-year-old man presenting with a luxation of a posterior chamber intraocular lens (IOL) with the capsular bag after ocular contusion. Preoperative axial length was 36.58 mm.

Intraocular foreign bodies. Factors influencing final visual outcome.

Purpose: To identify the prognostic factors of poor visual outcome (visual acuity < or =6/240) in eyes with intraocular foreign bodies.

Methods: The records of 95 consecutive patients were retrospectively reviewed for 6 years (1990-1995). All eyes underwent a primary surgical repair and foreign-body removal (electromagnet or vitrectomy).

Wagner vitreoretinal degeneration with genetic linkage refinement on chromosome 5q13-q14.

Background: It has been previously described that Wagner disease is linked to chromosome 5q13-q14. This study was carried out to describe the ophthalmological aspects and report the results of genetic linkage analysis in a large pedigree affected by Wagner disease.

Methods: Fourty members of one same family agreed to be examined.

Visual outcome and prognostic factors after magnetic extraction of posterior segment foreign bodies in 40 cases.

Aims: To evaluate the clinical features as well as the visual and anatomical outcome in eyes with magnetic posterior segment foreign bodies, to identify prognostic factors after removal using an electromagnet.

Methods: The records of 40 patients with posterior segment foreign bodies were retrospectively reviewed for 6 years (1989-94). Post-traumatic cataracts and secondary retinal detachments were treated using conventional surgical techniques.

Transient acute myopia induced by antilymphocyte globulins.

Acute onset of transient myopia may be induced by several drugs, different mechanisms having been described. We report the occurrence of such an event after intravenous administration of equine antilymphocyte globulins in a patient treated for aplastic anemia. Clinical ocular examination revealed no other abnormality, and ultrasonography disclosed no swelling of the ciliary body.

[Nummular keratopathy in Crohn's disease. Apropos of a case].

We report an unusual case of nummular keratopathy of the left eye in a 58-year-old woman with active Crohn's disease, presenting colo-anal and joint symptoms. Spontaneously decreased bowel activity and local steroid treatment provided symptom relief and incomplete decrease in volume of subepithelial elevations. We discuss the clinical aspects, the epidemiologic factors, the pathogenic mechanisms and the treatment of keratopathy in Crohn's disease.

[Capsular bag distension syndrome after capsulorhexis].

We present one case of capsular bag distension associated with lens phacoemulsification, capsulorhexis and posterior chamber intraocular lens (IOL) insertion. Capsular bag distension is a rare postoperative complication of continuous tear anterior capsulotomy and presents the following characteristics: (1) postoperative myopic over-refraction; (2) shallowing of the anterior chamber associated with anterior shift of the IOL and the iris diaphragm; (3) important posterior distension of the posterior capsule and (4) sealing of the capsule to the anterior surface of the IOL. In our case, recovery of vision was incomplete after cataract surgery although the procedure was uneventful and no other ocular pathology was found.

[Vitrectomy and proliferative diabetic retinopathy. Apropos of 66 eyes].

Purpose: We report a retrospective study about vitrectomy in diabetic patients and the analysis of anatomical and functional results after surgery.

Methods: We studied 66 eyes of 52 diabetic patients who underwent pars plana vitrectomy. Vitrectomy was performed for nonclearing intravitreous hemorrhage in 75% of eyes and for tractional macular retinal detachment in 14% of eyes.
