2、溢泪症：长期溢泪，内眦附近皮肤潮红、粗糙、发生湿疹，因患者不断向下揩拭，可促使下睑外翻。

3、泪道堵塞不畅：(1)泪小点闭塞：泪小点呈膜性闭锁;(2)泪小管阻塞：从泪小点入针，液体立即从泪小点返流;(3)鼻泪管阻塞：从下泪点进针，先略顺利，后从上泪点流出，无粘液性或脓性分泌物返流; (4)鼻泪管狭窄：从泪小点进针，部分液体返流，少量液体通过流入鼻咽部。

以泪液的分泌过多或者泪道阻塞的检查为中心，做好下面三项检查。

1.席尔梅尔氏试验：使用试纸条，测定每分钟的泪液分泌量。猫正常情况下可使试纸湿润10~15mm，很少有超过20mm的，如超过23mm，则说明异常。

2.氢化荧光素通过试验：将1滴1%的氢化荧光素液点眼，60秒钟后洗眼除去氢化荧光素，使用荧光灯观察鼻孔，见到荧光者为阳性，没见到者为细菌性。细菌性者说明泪道有阻塞。但是有些猫经过5~10分钟才出现，所以zui后的判定要等到10分钟以后再进行。

3.泪道x线造影检查：主要是为了调查泪囊和鼻泪管的阻塞。事先从上泪点注入生理盐水，压迫泪囊，确认有洗液从下泪点流出后，用有机碘造影剂注入后x线摄影。有泪道阻塞时可见到造影剂停留该处。

流泪的治疗和预防方法

沙眼急性发病导致流泪症状的的预防：

沙眼衣原体常附在病人眼的分泌物中，任何与此分泌物接触的情况，均可造成沙眼传播感染的机会。

因此，应加强宣传教育，把防治眼病的知识传给群众，贯彻预防为主的方针。培养良好卫生习惯。不用手揉眼，毛巾、手帕要勤洗、晒干;托儿所、学校、工厂等集体单位应分盆分巾或流水洗脸，对沙眼病人应积极治疗，加强理发室、浴室、旅馆等服务行业的卫生管理，严格毛巾、脸盆等消毒制度，并注意水源清洁。矫正睑外翻，使泪小点位置恢复正常，同时治疗睑缘炎。泪小点狭窄或闭塞者行泪小点扩张术，泪点切开或咬切术。泪小管或总管阻塞者，轻者可用探针强行扩张后，进行穿线插管术。严重者可作结膜泪囊吻合术或插管术。或借自身静脉搭桥以沟通泪囊及结膜。当我们的眼睛看东西时把一个物体看成两个，造成视物双影，这就是复视。专业的定义则为，在正常视网膜对应的前提下，一个物象落在分开过大的视网膜非对应点上，不能形成双眼单视，而将一个物体看成两个。分为单眼复视和双眼复视。上、下直肌收缩时，眼球上转或下转，同时还使眼球内转；上斜肌主要使眼球内旋，同时还使眼球下转和外转；下斜肌主要使眼球外转，同时还使眼球上转和外转。

2, overflow tears: Long-term overflowing tears, flushing near the skin flushing, rough, eczema, as patients continue to swab down, can promote lower eyelid valgus.

(3) lacrimal passage blocked blocked: (1) punctatus occlusion: punctum was membranous atresia; (2) lacrimal duct obstruction: from the punctum into the needle, the liquid immediay from the tear dot reflux; (3) Nasolacrimal duct obstruction: from the point of punctum into the needle, the first slightly smooth, then flow from the tear point, no mucinous or purulent discharge reflux; (4) nasolacrimal duct stenosis: from the punctum into the needle, the part Liquid reflux, a small amount of liquid through the nasopharynx.

To excessive secretion of tears or lacrimal duct obstruction as the center, do the following three checks.

1. Schmelmeier's test: the use of special test strips, the determination of tear secretion per minute. Cats under normal circumstances make the test paper moist 10 ~ 15mm, very few more than 20mm, such as more than 23mm, then abnormal.

2. Hydrotalcitin through the test: a drop of 1% hydrogen fluorescein liquid eye, eye wash after 60 seconds to remove hydrogen fluoride, the use of fluorescent light to observe the nose, see the fluorescence were positive, did not see the bacteria. Bacterial who shows lacrimal duct obstruction. However, some cats appear after 5 to 10 minutes, so the final judgment will be waited until 10 minutes later.

3. Lacrimal x-ray examination: mainly to investigate the lacrimal sac and nasolacrimal duct obstruction. Prior to injection of saline from the punctum, oppression lacrimal sac, confirm the washings from the next punctate flow, the injection of organic iodine contrast agent after x-ray photography. Lacrimal obstruction can be seen when the contrast agent to stay there.

Tears treatment and prevention methods

Acute trachoma leads to the prevention of tearing signs:

Chlamydia trachomatis often attached to the patient's eye secretions, any contact with this secretions, can cause trachoma spread of infection.

Therefore, publicity and education should be stepped up and the prevention and treatment of eye diseases should be passed on to the masses and the principle of prevention should be followed. Develop good health habits. Do not rubbed his eyes, towels, handkerchiefs to wash, dry; nurseries, schools, factories and other collective units should be divided into sub-branches or wash water, the trachoma patients should be actively treated to strengthen the barber room, bathroom, hos and other service industries Health management, strict towels, washbasins and other disinfection systems, and pay attention to clean water. Correction of eyelid eversion, so that the location of the punctuality returned to normal, while treating blepharitis. Narrow stenosis or occlusion of small tears point dilatation surgery, tear open or bite incision. Lacrimal tuberculous or obstruction of the Explorer, the light available probe for the expansion of force, threading intubation. Serious cases can be used for conjunctival dacryocystorhinostomy or intubation. Or by their own vein to bridge the lacrimal sac and conjunctiva. When we look at something in the eyes of an object as two, resulting in double vision, this is double vision. Professional definition is that under the premise of normal retinal correspondence, an object falls on the retinal point of separation is too large, can not form binocular vision, and an object as two. Divided into monocular diplopia and binocular diplopia. Upper and lower rectus muscle contraction, the eye turn or turn down, but also to make the eye turn; upper oblique main eyeball pronation, but also to the eye turn and outside the turn; lower oblique mainly outside the eyeball, At the same time also make the eye turn up and turn outside.
