Compared to preserved eyedrops, preservative free eyedrops are significantly less associated with ocular symptoms and signs of irritation.

Compared with Na-HY, OsPr-CMC was noninferior in terms of efficacy and safety, preferred by patients, and easier to use. Osmoprotection using OsPr-CMC therefore represents a viable option for dry eye disease management.

Based on the most likely hypotheses concerning disease duration and non-responding ophthalmologists' VKC case rate, the best estimate of VKC prevalence in Western Europe is 3.2/10,000 inhabitants. The prevalence of VKC with corneal complications is 0.8/10,000 inhabitants.

The safety and immunogenicity of a monovalent inactivated vaccine against Leptospira interrogans serogroup Icterohaemorrhagiae was evaluated in 84 volunteers according to the route of administration, i.e., subcutaneous (SC) or intramuscular (IM), in a double-blind randomised trial. The volunteers were randomised into four groups: SC vaccine; IM vaccine; SC placebo; and IM placebo. Primary vaccination comprised two injections on day 0 and day 14, with a booster after 6 months. A second booster was given 30 months after primary vaccination. Local reactions within 1 h of injections were rare, with no difference between vaccine groups. Local reactions within 3 h were more frequent after the second, third and fourth SC injections than after IM injections. Systemic reactions never occurred within 1 h of vaccination and were rare within 3 days; the rates were comparable for the different vaccine groups. Evolution of the antibody responses, as assessed by microscopic agglutination tests and specific IgG and IgM ELISAs, were similar for both injection routes. IgG seroconversion rates after the first booster were 97% (95% CI 80-100%) for the SC vaccine group, and 96% (95% CI 80-100%) for the IM vaccine group, and both reached 100% for IgG after the second booster. The safety and immunogenicity of the anti-leptospiral vaccine were both good. Monitoring of antibody levels established that a booster dose triggered a strong antibody response in fully vaccinated subjects at 30 months after primary vaccination.

The use of povidone 2% preservative-free eyedrops was associated with an improvement in symptoms during sustained computer use. Any of the three instillation modalities decreased symptoms of ocular tiredness, dryness, and difficulty of focus; maintained an unchanged corneal surface; and improved dynamic visual acuity. Therefore, the most patient-friendly modality (patient's own instillation modality from symptom onset) could be recommended to contact lens wearers with computer visual syndrome.

Azithromycin 1.5% for 3 days was as effective and as safe as tobramycin for 7 days. Furthermore, more azithromycin than tobramycin patients presented an early clinical cure at Day 3. Due to its twice daily dosing regimen for 3 days, azithromycin represents a step forward in the management of purulent bacterial conjunctivitis, especially in children.

Once daily instillation of T1225 1.0% and 1.5% was shown to reach an AUIC markedly above the required threshold for an antibacterial activity against Gram-positive bacteria (25-35). These results suggest that a BID instillation is more likely to ensure antimicrobial activity against Gram-negative bacteria (threshold >100).
