[High-altitude retinopathy]. / Retinopatía de gran altura.

CASE REPORT: This case report presents a 36 year-old male with a sudden loss of vision while taking part in an expedition in the Daulaghiri (8,167 metres high peak located in the Himalayan Mountain Range). DISCUSSION: High altitude retinal haemorrhage is a common condition in those mountaineers who reach altitudes over 5,500m. Depending on its location it may not present any symptoms and the condition improves with no further complications. However, in case of macular involvement the vision decreases dramatically and the consequences are uncertain.

Retinopatía de gran altura / High-altitude retinopathy

Caso Clínico: Varón de 36 años que presenta pérdida súbita de visión central, durante una expedición al Daulaghiri (cordillera del Himalaya), de 8.167 m de altitud. Discusión: Las hemorragias retinianas de la altura son una manifestación frecuente en montañeros que superan los 5.500 m de altitud. Según su localización puede cursar deforma asintomática y suele evolucionar favorablemente. En caso de afectación macular, la visión disminuye de forma drástica y el pronóstico es incierto(AU)

Ocular alignment under general anesthesia in congenital esotropia.

Ocular alignment is usually more divergent in strabismus patients under general anesthesia than in the awake state. Although clinical and anesthetized alignments have been reported to be correlated through the equation A = 0.8P + 30, significant differences in the amount of divergence under anesthesia have been reported between esotropes and exotropes. We found differences in response to general anesthesia in a group of 83 congenital esotropes. The averaged anesthetized alignment pertained to the whole group of 6.2 prism diopters of esotropia, which correlated poorly with the preoperative deviation. Mean anesthetized alignments were similar for any amount of preoperative deviation. Recommendations of intraoperative adjustment of surgery based on the anesthetized position should, in our opinion, be reconsidered and recalculated when treating congenital esotropes. A prediction of surgical results following these recommendations suggested an increase of the undercorrection rate, probably linked to an incorrect identification of normal and anomalous cases to the Apt-Romano test.
