[Results of low-vision rehabilitation in vision impaired patients].

Purpose: Diseases of the retina, the optic nerve and the cornea may lead to a non-treatable loss of central vision. We report on low vision rehabilitation in 100 vision impaired patients.

Methods: Low vision rehabilitation was performed in 100 consecutive patients (61 % AMD, 23 % diabetic retinopathy, 16 % other diseases).

[Quantitative assessment of topographical parameters to differentiate keratoconus from pellucid marginal corneal degeneration and ].

Introduction: The purpose is to compare videokeratometric data (Fourier series harmonic analysis and wave-front analysis) in eyes with ectatic corneal disease (keratoconus; pellucid marginal corneal degeneration [PMCD]) and to determine parameters for early diagnosis and distinction of keratoconus and PMCD.

Patients And Methods: 13 eyes with PMCD, 32 eyes with keratoconus and 18 healthy eyes were included. Computerized videokeratographic methods were assessed, using Fourier series harmonic analysis, Zernike coefficients and eccentricity.

Contact lenses and special back surface design after penetrating keratoplasty to improve contact lens fit and visual outcome.

Aims: To describe the fitting of patients with high or irregular astigmatism following penetrating keratoplasty with contact lenses and to answer the question whether or not contact lenses with special back surface design can improve visual acuity in complex cases after penetrating keratoplasty.

Methods: 28 eyes were included. They were fitted with contact lenses with a special back surface that was designed for optical rehabilitation after penetrating keratoplasty.
