[Cornea imagery and keratitis caused by processionary caterpillar hairs]. / Apport de l'imagerie cornéenne dans la kératite à poils de chenilles processionnaires.

INTRODUCTION: With their ability to migrate into the cornea and release toxins, caterpillar hairs can induce different clinical presentations such as conjunctivitis, keratoconjunctivitis, uveitis, and less frequently vitreoretinal inflammation (hyalitis, papillitis, macular edema). OBSERVATION: We report a case that occurred in Alsace (France) in a 13-years-old boy presenting with keratitis caused by caterpillar hairs. We localized them in the cornea, for the first time, using confocal microscopy and anterior segment spectral optical coherence tomography. CONCLUSION: Confocal microscopy and spectral optical coherence tomography can be useful for diagnosis and follow-up of this disease.

RETIDIAB®: assessment of a continuing medical education website for the improvement of diabetic retinopathy management.

AIM: The aim of this study was to evaluate the efficacy of a continuing medical education (CME) website to improve ophthalmological management of diabetic retinopathy (DR). METHODS: A worldwide website called RETIDIAB® was created in which, to log on for first time, users had to take a preliminary test to evaluate their baseline level of knowledge. This allowed them free access to the entire website at any time with no time obligation. The website comprised a course of theoretical concepts and different types of training, including multiple-choice questionnaires (MCQ) focused on the course content, interpretation of diabetic fundus photographs and case reports. After perusing the entire RETIDIAB® website, users could take a second assessment test. Finally, they were asked to fill in a questionnaire evaluating the entire programme. RESULTS: A total of 137 users were registered and, of these, 109 took only the preliminary test, while 28 took the second test and evaluated the entire website; of the latter, 75% were residents and 25% were practising physicians, and 15 were male and 13 were female, ranging in age from 26 to 42 (30.2 ± 3) years. Statistically significant progress was seen between the first and second evaluations (37.3 ± 14% correct answers vs 64 ± 10%, respectively), and the average time interval between the first and second evaluations was 40 ± 20 days. In addition, users expressed a high level of overall satisfaction with the site. CONCLUSION: This pilot study demonstrated the value and effectiveness of RETIDIAB®, a new CME website exclusively devoted to DR management.

[Study and prevention of contact lens-related microbial keratitis with a standardized questionnaire]. / Utilité d'un questionnaire standardisé dans la prise en charge et l'étude épidémiologique des kératites infectieuses sous lentilles de contact.

INTRODUCTION: microbial keratitis is a significant health concern for the one million wearers of contact lenses and their ophthalmologists, with some potentially modifiable risk factors. The number of risk factors for contact lens-related microbial keratitis has been described, but many of them still remain assumed or unknown. PATIENTS AND METHODS: a multicenter prospective case-control study was conducted in 12 French university hospitals (Besançon, Bordeaux, Dijon, Fort-de-France, Grenoble, Limoges, Lyon, Nancy, Nantes, Paris, Marseille and Strasbourg) beginning in July 2007 on contact lens wearers presenting with microbial keratitis and on healthy contact lens wearers. Patients and healthy wearers were interviewed using a 51-item anonymous standardized questionnaire to determine subject demographics and contact lens wear history. RESULTS: two hundred and fifty-six patients with microbial keratitis were included. One hundred and thirteen healthy contact lenses wearers were surveyed. Cosmetic contact lens wear highly increased the relative risk (RR) of microbial keratitis (RR, 16.5). Time since the last visit to an ophthalmologist longer than 1 year (RR, 3.4) or prescription by someone other than an ophthalmologist (RR, 7.6) also increased the risk of microbial keratitis. Education on lens care and handling was deficient (hand washing: RR, 2.2; rub and rinse: RR, 2.7). DISCUSSION: a standardized questionnaire is a powerful tool to determine risk factors for contact lens-related microbial keratitis, but also to analyze individual mistakes in contact lenses use and care.

Screening for diabetic retinopathy in a rural French population with a mobile non-mydriatic camera.

AIM: The aim of this study was to evaluate the yield of diabetic retinopathy (DR) screening in a rural population using a mobile non-mydriatic camera. METHODS: The 72 least medicalized areas of Burgundy were the target areas. An orthoptist took fundus photographs using a Topcon TRC-NW6S non-mydriatic camera (four fields: posterior pole; nasal; temporal; and upper). Interpretations were done in the Department of Ophthalmology according to the classification of the French Language Association for the Study of Diabetes and Metabolic Diseases (Alfediam). RESULTS: Between 2004 and 2006, 1974 diabetics were screened-676 the first year, and 1298 in the second. The rate of non-interpretable photographs was 13%. Of the 1974 screened patients, there were 103 cases of DR (5.2%), comprising 70 mild non-proliferative DR (68%), 21 moderate non-proliferative DR (20.4%) and 12 severe non-proliferative DR (11.6%). The mean age of the patients with a DR was 66.7+/-10.9 years, with a mean duration of diabetes of 16.5+/-9.8 years. Only 35 (34%) patients were aware of their HbA(1c), which had a mean value of 7.8% and 19 had visited an ophthalmologist in the year before screening (18.4%). After the initial screening, 90,5% of the patients consulted an ophthalmologist as recommended. CONCLUSION: Screening improved the quality of the ocular follow-up in diabetics in this rural area. However, improvements in management are needed to lower the cost of such a programme.

[Combined glaucoma and diabetic retinopathy screening in Burgundy]. / Dépistage itinérant du glaucome associé à celui de la rétinopathie diabétique en Bourgogne.

INTRODUCTION: The aim of this study was to evaluate the yield of glaucoma and ocular hypertension (OHT) screening in association with diabetic retinopathy (DR) screening in a rural population. PATIENTS AND METHODS: 676 patients were screened between 2004 and 2005. The four departments the Burgundy region were visited, divided into 39 areas with sparse medical services. Each patient had fundus photographs taken with a nonmydriatic camera and IOP measurement in each eye with a noncontact tonometer. Optic discs were classified into suspect or normal. RESULTS: On the 676 screened patients, 41 presented an anomaly (6.1%): 31 with OHT (4.6%), 7 with a suspect optic disc (1.0%), and 3 with both anomalies (0.4%). After further control, we finally found 4 cases of OHT (0.6%) and 8 cases of glaucoma (1.2%). This screening program allowed the diagnosis of 2 new cases of OHT (0.3%) and 4 new cases of glaucoma (0.6%). DISCUSSION: This screening improved the quality of the ophthalmic follow-up in rural areas for diabetics. Furthermore, it is a simple and not more expensive way to screen for OHT and glaucoma in these populations. CONCLUSION: The itinerant screening of OHT and glaucoma combined with a diabetic retinopathy screening is effective. The screening campaign was renewed for 2 years in semi-rural zones.

Bilateral optic neuropathy revealing Sjögren's syndrome.

INTRODUCTION: The central nervous system involvement has been reported in 20% of cases of primary Sjogrën's syndrome (SS), a chronic autoimmune disease characterized by a disorder of the exocrine glands secondary to progressive lymphocyte infiltration. Classically described neurological manifestations include sensorimotor deficits, aseptic meningitis or meningoencephalitis, multiple sclerosis-like syndromes and myeolopathies. OBSERVATION: We report here the case of a 53-year-old woman who exhibited rapidly progressive visual loss, disclosing bilateral optic neuropathy, as an uncommon initial symptom of primary SS. Examination of CSF revealed associated aseptic meningitis. Because of the lack of efficacy of the first treatment by intravenous corticosteroids, monthly intravenous cyclophosphamide was quickly introduced. After six months, significant visual recovery was observed. CONCLUSION: Optic neuropathies have been rarely reported as the initial symptom revealing primary Sjogrën syndrome, and bilateral simultaneous lesions remain exceptional.

Changes in meibomian fatty acids and clinical signs in patients with meibomian gland dysfunction after minocycline treatment.

AIMS: To assess the changes in ocular surface abnormalities and meibomian fatty acid composition in patients suffering from meibomian gland dysfunction (MGD) after treatment with oral minocycline associated with lid hygiene versus lid hygiene only. METHODS: We evaluated the break-up time, corneal staining and quality of meibomian excreta, and collected meibomian oil in 20 individuals suffering from MGD before and after 8 weeks of minocycline associated with lid hygiene (n = 10) or lid hygiene only (n = 10). Meibomian fatty acids were directly transmethylated and analysed by gas chromatography (GC) and GC mass spectrometry. RESULTS: The meibomian fatty acid composition was slightly modified after 8 weeks in both groups. The decrease in a branched-chain fatty acid (isoC20) was greater after minocycline treatment than after lid hygiene only (-65% and -25%, respectively; p<0.05). Other fatty acids were unchanged. A significant improvement in the BUT was observed after minocycline treatment (p = 0.03). CONCLUSION: This study showed better tear film stability after minocycline treatment and a biological effect on meibomian fatty acid composition in MGD patients. Minocycline was more effective than lid hygiene alone. Both interventions partly corrected fatty acid composition abnormalities. Among the fatty acids, isoC20 could be a biological marker of MGD.

[Iris heterochromia in acquired Horner's syndrome]. / Hétérochromie irienne associée à un syndrome de Claude Bernard-Horner acquis.

Horner's syndrome (HS) is related to an interruption of the oculosympathetic nerve pathway. The classic clinical findings associated with this condition are ptosis, miosis, and enophthalmos. Heterochromia is typically described in congenital HS, but it is an uncommon finding in acquired HS. We report a case of post-traumatic HS associated with heterochromia. A literature review indicates that this type of heterochromia may be related to a reduction in the number of iris melanocytes. This mechanism may be the same in the physiological iris color modifications in adulthood.

[Third cranial nerve palsy related to an unruptured aneurysm of the posterior communicating artery]. / Paralysie du nerf oculomoteur commun liée à un anévrisme non rompu de la communicante postérieure.

The posterior communicating artery (PCA) aneurysm is a traditional cause of young subjects' painful ophthalmoplegia. We report the case of a patient presenting a complete, extrinsic and intrinsic, third cranial nerve palsy related to an unruptured aneurysm of the PCA. The diagnosis was made with the angio-CT, and the patient was treated with endovascular treatment for 6 days after the beginning of the cephalalgias. Recovery was complete at 8 weeks. We review the literature on the etiologies of this type of attack, the work-up, and the possible treatments.
