Recently, the population of people exploring High Mountain trekking or expedition is increasing as an increase in the backpackers. Many accidents occurring at High Mountain above 6,000 m are the results of snow blindness. The damage of cornea and/or retina is direct cause of snow blindness. The UV intensity increases on the hand, along with the altitude caused by decrease in the atmospheric pressure, on the other hand the reflections by bright snow at high mountain area. And it increases approximately 3 times and 4 times higher than the ground level at altitude of 4,000 m and 8,000 m, respectively. The use of sunglasses is more favorable than goggles for the protection of snow blindness at High Mountains. The eye frames that have high mechanical strength and the plastic lenses which can protect UV 100% are recommended. The attachable shielding pads are needed to prevent the incident UV light reflected or scattered from the gap between glasses frame and face. The sunglasses must have flexible and long temples to wind the ears adequately for the prevention of detachment during climbing and it is recommended that the metal frame to be coated with plastics to prevent the eye surroundings from frostbite.

설갑상선은 주로 설맹공과 후두개사이에서 발생하는 일종의 이소성 갑상선으로서, 비교적 희귀한 질환으로, 1869년 Hickman이 처음으로 보고한 이래, 외국에서는 약 300례 정도의 보고가 있다. 최근 저자들은 48세 남자에서 정상 위치에 있어야 할 갑상선이 결여되고, 설갑상선 만이 있는 1례를 우연히 발견해서, 갑상선 scan 으로 확인할 수 있었기에 문헌적 고찰과 함께 보고하는 바이다.
