[Quality of vision after cataract surgery in patients with prolate aspherical lens].

PURPOSE: To assess the quality of vision in pseudophakic patients with a prolate aspherical intraocular lens (IOL) compared to patients with a spherical IOL. PATIENTS AND METHODS: Twenty patients undergoing cataract surgery were divided into two groups according to the type of IOL: ten prolate aspherical IOLs (TECNIS Z9000, AMO, USA) and ten spherical IOLs (911 CeeOn Edge, AMO, USA). The integrity of ocular functions was assessed with clinical examination and multifocal electroretinogram. Contrast sensitivities were tested preoperatively in photopic, mesopic, and glared conditions. Postoperative examinations included refractive evaluation before and after mydriasis, pupil diameter, contrast sensitivities, and wavefront aberration analysis. RESULTS: Postoperative best-corrected visual acuity was 0.95 +/- 0.13 for the TECNIS group vs 0.98 +/- 0.11 for the 911 group (p=0.32). Refractive evaluation revealed mydriasis myopic shift in patients with the 911 IOL (- 0.10+/-0.30 D for the TECNIS group vs - 0.68+/-0.21 D for the 911 group, p=0.002). Mesopic contrast sensitivity was improved in the TECNIS group regarding medium and high spatial frequencies (p=0.003 and p=0.002, respectively), whereas photopic and glared contrast sensitivities were equal in both groups. RMS for high-order aberrations was 0.36 +/- 0.07 microm in the TECNIS group vs 0.33 +/- 0.19 microm in the 911 group (p=0.21), and spherical aberration was lower in patients with TECNIS IOL (Z40=0.03+/-0.06 microm vs 0.20+/-0.14 microm, for the TECNIS group and the 911 group, respectively, p=0.029). CONCLUSION: Combining contrast sensitivities and wavefront aberration analysis provided an objective assessment of the quality of vision in pseudophakic patients. Using prolate aspherical IOL could reduce spherical aberration and improve visual acuity, especially in mesopic conditions.

[The central visual field in flicker stimulation].

The authors reported their results of flicker visual field in ganzfeld and 17 central points with 3, 8, 15 and 35 Hertz flicker. They tested 4 groups of control subjects and 12 patients with glaucoma. The flicker visual field may be a useful aid in determining campimetric abnormalities for glaucoma patients with normal static perimetry.

[Epidemiology of pediatric paracetamol poisoning (retrospective analysis of calls received by the Poison Control Center of Tours)].

The authors analysed 101 phone calls received in 3 years and 8 months at the Poison Control Center of Tours for paracetamol poisoning in children under 15 years of age. 70% of children were between 1 and 5 years old, 15% under 1 year and 15% over 5 years old. The kind of poisoning differ according to age: iatrogenic in 93% of cases under 1 year old (medication given by parents; error in dosage); accidental in 85% of cases between 1 and 5 years old and "willful" poisoning (43%) or accidental (36%) over 5 years old. The average quantity of ingested paracetamol was low (58mg/kg). The delay before phone call from an individual or a doctor was usually quite short. The neurologic or digestive signs were present in 12% of the children. The outcome was uneventful in all cases indicating that this form of poisoning is being in childrens.

[Local catastrophe and C.A.P.: apropos of 1 plant in Touraine].

Drinking water supply to a 200,000 inhabitant urban area had to be interrupted owing the pollution of the Loire river due to fire in a chemical plant in the vicinity of Tours. This event showed a regretful lack of information diffusion making the role of the Poison Control Center more difficult. Consequences related to acute toxicity were negligible but the evaluation of long-term risk is still pending.
