2、溢淚癥：長(zhǎng)期溢淚，內(nèi)眥附近皮膚潮紅、粗糙、發(fā)生濕疹，因患者不斷向下揩拭，可促使下瞼外翻。

3、淚道堵塞不暢：(1)淚小點(diǎn)閉塞：淚小點(diǎn)呈膜性閉鎖;(2)淚小管阻塞：從淚小點(diǎn)入針，液體立即從淚小點(diǎn)返流;(3)鼻淚管阻塞：從下淚點(diǎn)進(jìn)針，先略順利，后從上淚點(diǎn)流出，無(wú)粘液性或膿性分泌物返流; (4)鼻淚管狹窄：從淚小點(diǎn)進(jìn)針，部分液體返流，少量液體通過(guò)流入鼻咽部。

以淚液的分泌過(guò)多或者淚道阻塞的檢查為中心，做好下面三項(xiàng)檢查。

1.席爾梅爾氏試驗(yàn)：使用試紙條，測(cè)定每分鐘的淚液分泌量。貓正常情況下可使試紙濕潤(rùn)10~15mm，很少有超過(guò)20mm的，如超過(guò)23mm，則說(shuō)明異常。

2.氫化熒光素通過(guò)試驗(yàn)：將1滴1%的氫化熒光素液點(diǎn)眼，60秒鐘后洗眼除去氫化熒光素，使用熒光燈觀察鼻孔，見到熒光者為陽(yáng)性，沒(méi)見到者為細(xì)菌性。細(xì)菌性者說(shuō)明淚道有阻塞。但是有些貓經(jīng)過(guò)5~10分鐘才出現(xiàn)，所以zui后的判定要等到10分鐘以后再進(jìn)行。

3.淚道x線造影檢查：主要是為了調(diào)查淚囊和鼻淚管的阻塞。事先從上淚點(diǎn)注入生理鹽水，壓迫淚囊，確認(rèn)有洗液從下淚點(diǎn)流出后，用有機(jī)碘造影劑注入后x線攝影。有淚道阻塞時(shí)可見到造影劑停留該處。

流淚的治療和預(yù)防方法

沙眼急性發(fā)病導(dǎo)致流淚癥狀的的預(yù)防：

沙眼衣原體常附在病人眼的分泌物中，任何與此分泌物接觸的情況，均可造成沙眼傳播感染的機(jī)會(huì)。

因此，應(yīng)加強(qiáng)宣傳教育，把防治眼病的知識(shí)傳給群眾，貫徹預(yù)防為主的方針。培養(yǎng)良好衛(wèi)生習(xí)慣。不用手揉眼，毛巾、手帕要勤洗、曬干;托兒所、學(xué)校、工廠等集體單位應(yīng)分盆分巾或流水洗臉，對(duì)沙眼病人應(yīng)積極治療，加強(qiáng)理發(fā)室、浴室、旅館等服務(wù)行業(yè)的衛(wèi)生管理，嚴(yán)格毛巾、臉盆等消毒制度，并注意水源清潔。矯正瞼外翻，使淚小點(diǎn)位置恢復(fù)正常，同時(shí)治療瞼緣炎。淚小點(diǎn)狹窄或閉塞者行淚小點(diǎn)擴(kuò)張術(shù)，淚點(diǎn)切開或咬切術(shù)。淚小管或總管阻塞者，輕者可用探針強(qiáng)行擴(kuò)張后，進(jìn)行穿線插管術(shù)。嚴(yán)重者可作結(jié)膜淚囊吻合術(shù)或插管術(shù)。或借自身靜脈搭橋以溝通淚囊及結(jié)膜。當(dāng)我們的眼睛看東西時(shí)把一個(gè)物體看成兩個(gè)，造成視物雙影，這就是復(fù)視。專業(yè)的定義則為，在正常視網(wǎng)膜對(duì)應(yīng)的前提下，一個(gè)物象落在分開過(guò)大的視網(wǎng)膜非對(duì)應(yīng)點(diǎn)上，不能形成雙眼單視，而將一個(gè)物體看成兩個(gè)。分為單眼復(fù)視和雙眼復(fù)視。上、下直肌收縮時(shí)，眼球上轉(zhuǎn)或下轉(zhuǎn)，同時(shí)還使眼球內(nèi)轉(zhuǎn)；上斜肌主要使眼球內(nèi)旋，同時(shí)還使眼球下轉(zhuǎn)和外轉(zhuǎn)；下斜肌主要使眼球外轉(zhuǎn)，同時(shí)還使眼球上轉(zhuǎn)和外轉(zhuǎn)。

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.
