Biometry and refractive outcome of eyes filled with silicone oil by standardized echography and partial coherence interferometry.

Background: We evaluated the validity of calculations for refractive outcome in cataract surgery in silicone oil-filled eyes. The retrosilicone space (RSS) was included in these calculations.

Methods: In a prospective study the axial length (AL) of silicone oil-filled eyes was measured.

[Echographic differential diagnosis of optic nerve widening].

Introduction: Standardized echography is a well-established examination technique in ophthalmology. Among other things one of the more important uses is the evaluation of the optic nerve and its abnormalities. One aspect is the use of the stretch-test (originally called the "30 degrees-test") for the differential diagnosis of optic nerve widening.

Choroidal ganglion cell plexus and retinal vasculature in monkeys with laser-induced glaucoma.

The choroid of primates possesses an elaborate nitrergic nerve fiber plexus containing a great number of ganglion cells. Postganglionic nerve fibers innervate mainly the choroidal vasculature. In addition, the choroid contains an elastic muscular system closely associated to the vasculature.

A study of aqueous humor dynamics in keratoconus.

Clinical observations suggest that patients with keratoconus have lower intraocular pressures, on average, than normal subjects. Our purpose was to determine whether differences in aqueous production and outflow facility could account for differences in intraocular pressure between a group of patients with keratoconus and a group of normal, age-matched control subjects. Aqueous humor dynamics were determined by the use of fluorophotometry in one eye of seven patients with keratoconus and ten age-matched normal subjects.
