Prospective study of corneal collagen cross-linking efficacy and tolerance in the treatment of keratoconus and corneal ectasia: 3-year results.

Purpose: To assess the efficacy and tolerance of corneal collagen cross-linking with corneal epithelium debridement in the stabilizing treatment of primary or secondary corneal ectasia.

Methods: Prospective, comparative, single-center study of patients presenting with progressive primary or secondary corneal ectasia. The control group, comprising the fellow eye of patients with bilateral involvement, was followed up for 6 months and then treated.

[Choroidal metastases of lung neoplasm treated with external radiotherapy and polychemotherapy: a study of four clinical cases].

Aim: To report the efficacy of external local radiotherapy in the treatment of choroidal metastases.

Patients And Methods: The study reports four cases of patients with choroidal metastases of lung neoplasm confirmed by the bronchial biopsy. Polychemotherapy was associated with external radiotherapy of the ocular metastases.

Detection of mild papilloedema using spectral domain optical coherence tomography.

Objective: To propose a method of diagnosis of mild papilloedema (PO) using peripapillary total retinal (PTR) thickness measurement by spectral domain optical coherence tomography (OCT).

Methods: 24 eyes in 24 patients with PO caused by increased intracranial pressure and 22 eyes in 22 normal subjects were studied. OCT high-quality fundus images were analysed and graded by three masked observers using the Modified Frisén Scale.

[Transient binocular visual loss: a diagnostic approach].

It is rarer for a patient to present with transient binocular visual loss than transient monocular visual loss. This symptom usually results from a cerebral dysfunction. When transient binocular visual loss results from papilledema, ophthalmological examination is critical for an accurate diagnosis.
