[Bioavailability of antibiotics].

To be effective, an antibiotic must achieve therapeutic concentrations at the site of infection. This article is a review on the bioavailability of local and systemic antibiotics. Amongst topical antibiotics, fluoroquinolones and fusidic acid have the best intra-corneal and intra-cameral penetration.

[Thiotepa eyedrops for prevention of pterygium recurrence: 18 years of use].

Seven patients having repeated inflammatory relapses of herpes simplex keratitis have been treated by small dosages of steroid eyedrops (from 0.25% prednisolone once a week to 1% prednisolone once a day). In these patients these doses were almost always sufficient.

[Value of pursuit motor electro-oculography in the investigation of esotropia from strabismic amblyopia (author's transl)].

The value of the pursuit motor electro-oculogram (pendular or linear) in the diagnosis and subsequent therapy of non-accomodative esotropia (not eliminated by optical correction), and presenting a spasmodic element, was studied in 164 cases of unoperated esotropia and 47 cases operated upon using a conventional technique and "Cuppers'thread". The contribution and limitations of this electrophysiological method for exploration of ocular motility in esotropia are discussed.
