[Ocular phototoxicity and altitude among mountain guides].

Purpose: This study aimed to evaluate ocular phototoxicity in mountaineer guides who experience overexposure to ultraviolet related to the altitude at which they work, as well as light reflection on snow.

Materials And Methods: Ninety-six guides and 90 controls living in plains, over 50 years old, underwent complete examinations. They responded to a questionnaire assessing altitude exposure and protective eyewear.

[Comparison between Lenstar LS 900 non-contact biometry and OcuScan RXP contact biometry for task delegation].

Introduction: Non-contact biometers have many advantages including the delegation of tasks to orthoptists. This study analyses the reliability of measurements comparing contact and non-contacts techniques.

Patients And Methods: Comparative measurements were taken on 86 eyes of 45 patients (mean age: 74 years; 44.

[Susac syndrome: variable onset modes and disease courses: two case reports].

Introduction: Susac syndrome is a rare microangiopathy of unknown etiology, which involves the clinical triad of encephalopathy, visual loss, and hearing loss. Several onset and progression patterns are possible.

Observation: Case 1: a 43-year-old woman developed subacute encephalopathy, which had not been diagnosed and had been evolving for 2 months, as well as left sensorineural hearing loss.

[Isolated occlusion of a cilioretinal artery].

Purpose: Isolated cilioretinal artery occlusion is uncommon but has characteristic features. Based on a case report and a review of the literature, we present the clinical findings and angiographic particularities of this syndrome and discuss controversial pathophysiological data.

Case Report And Method: A 56-year-old man had sudden visual loss in the right eye estimated at 3/10 P10.
