眼底出血(一)
西医的认识： 顾名思义，眼底出血是一种临床表现，并不是一种病名，引起眼底出血的原因很多，如高血压视网膜病变、糖尿病视网膜病变、眼底动脉血管瘤、视网膜静脉栓塞、眼外伤等等，均可导致眼底出血。由于各种不同的病因导致相同的病理损害，如视网膜出血，渗出,微血管瘤、新生血管等。 本病由于病因复杂，所以病程长，易反复发作，严重影响视力，引起诸多严重的并发症。如黄斑病变(黄斑囊样水肿、黄斑变性)，新生血管性青光眼、玻璃体积血、视神经萎缩、增殖性视网膜病变、牵拉性视网膜脱离，如不及时有效的治疗，常可导致失明。
中医的认识： 中医解释眼底出血属于中医血证范畴，《灵枢•决气》云：“中焦受气，变化而赤，是谓血。”《景岳全书•杂证谟》云：“凡七窍之灵，为四肢之用……凡形质所在，无非血之用也。”后世医家根据《灵枢•大惑论》记载：“五脏六气之精气，皆上注于目而为之精，精之窠为眼，骨之精为瞳子，筋之精为黑眼，血之精为络，其窠气之精为白眼，肌肉之精为约束，裹颉筋骨血气而与脉并为系，上属于脑，后出于项中。”将其发展中医五轮学说。故眼底出血又属于中医学的“内障”眼病范畴。根据各种眼病病变所引起的不同程度的视功能障碍而有不同的称谓，如“暴盲”、“云雾移睛”、“视瞻昏渺”等本病病程较长，危害诸多，严重影响患者视力，并能引起视网膜脱离等重症。
起病要点：
1、眼底出血的根源，其实质与患者自身血液的质量改变有关。高血脂、高血糖、全血粘度超标、血流动力学下降、血管壁基底膜增厚、无菌杂质沉淀、血管管腔变窄、韧性降低、通透性增加都为眼底出血提供了必备的条件。2、同时由于供血不足导致视网膜及视觉神经系统因缺氧、缺水发生病变。血栓堵塞、管内压增高导致血管渗血或局部破裂也是出血的最直接诱因。症状体征：
(1)突然眼前一片漆黑，仅见手动或仅有光感。 (2)骤然间眼前如有圆的黑影遮住，不随眼转动而漂浮，正中方向注视物体完全不见，两旁物体则模糊可见。 (3)突然眼内有如线条状黑影向某一方向直射，进展迅速，且逐渐加多，最后终至遮住眼前，视物一片模糊，无法分辨。 (4)骤然眼前出现红光闪闪，逐渐加多，以致红光满目，视物不明。 (5)发病先兆，多数有眼胀，眼珠跳动等感觉。 (6)多数反复发作，每次发作，亦有以上某些症象，即使积血不退，当继续出血时，还可能有以上的某些感觉。 由于眼底出血的原因及部位不同，预后及对患者视力的影响也不一样，依照出血量的多少，出血部位不同而产生不同的症状。如出血量少，位于视乳头及视网膜周边部，可以没有明显的症状，如出血量多，患者感到眼前有黑影浮动，视线被部分或完全遮挡，仅剩光感的视力。如出血位于视网膜中心(黄斑区)患者中心视力丧失，即中心区视物不清有暗影遮挡，周边尚有部分视力预防及注意事项：
1、预防出血宜用眼适度，不要干重体力活，不要作俯卧撑及剧烈活动，不要长时间看书报、电视，建议看过40分钟后休息2～3分钟，不要过度兴奋、疲劳、激动或恼怒，保持良好和充足的睡眠，避免服用坚硬食物，注意补充含适应维生素类的蔬菜，瓜果。 2、睡眠充足有助于滋润眼睛，减少眼睛的血丝。 3、清洁眼睑，以免因残屑、油脂、细菌、化妆品等尘屑导致眼睛发炎，布满血丝。 4.早点睡，不要等到12点睡，那已经很晚了，最好是10点之前。睡眠时间以8小时为宜。放松点，多做点户外活动。出现眼底出血后首先要卧床休息，避免活动和精神紧张，做好血压、血糖等的控制。 5、要少吸烟、少饮酒，少吃有刺激性的食物，禁喝浓茶或咖啡Service Box Type 1
