And treatment of pterygium

Key words: pterygium Abstract Objective To investigate the occurrence of pterygium surgery and the relevance of drug treatment. Methods 1073 cases of 1186 patients to take all of pterygium surgery and local administration. Results for 2 years of 1186 and other treatment relative ratio, greatly improving the cure rate. Resting on the early development and pterygium, the cure rate reached 100%, quiescent and recurrent pterygium cure rate to more than 5 ‰. Conclusion surgery and topical treatment of pterygium is an effective way. Chinese papers League finishing. Key words pterygium; surgery; treatment 2001 年 1 month to December 2003 in our hospital on the pterygium (hereinafter referred to as pterygium) to do further study, based on its implementation of the pathogenesis of surgery and local injection therapy, with good results, are presented as follows. Clinical data 1.1 1 General information 1186 in the 1073 cases the eyes of 651 patients 722 male and female 422 cases 464; 639 farmers, 434 cases other professional. Onset of 486 432 cases of pterygium, the period 507 471 cases of pterygium, quiescent period 122 109 cases of pterygium, pterygium recurrence in 61 cases of 71 eyes. 1035 cases as outpatients, 38 patients were hospitalized patients. All patients had used drugs, some antibiotics, corticosteroids, use of local points, and some local injection of Bleomycin and other treatment effects are unsatisfactory. 1.2 staging (1) quiescent pterygium head and neck body three clear, thin head, stretching a film in or near the pupil pupil area, vascular fuzzy thinning blood supply interruption. (2) the period of pterygium, local recurrent congestion and edema, corneal end was extended in hypertrophic processes, is rich in vascular invasion, signs of ministries is unclear. (3) The onset of pterygium, local congestion, showing island-like uplift, exposure to the limbal side. (4) recurrent pterygium, in the external stimulus, repeatedly increased congestion,[link widoczny dla zalogowanych], mucosal levels of disorder, and continue to proliferation of adhesion, easy to form this great period of pterygium. 1.3 treatment of ocular surface anesthesia and intraoperative local anesthesia, the use of small scissors for pterygium 1mm up and down outside the conjunctival incision parallel with pterygium, iris restorer placed parallel to the head end of pterygium stripping fully exposed sclera, and then for the semi-circular neck pterygium and conjunctival separation, until the pterygium roots, cut pterygium, conjunctival lies flat, the upper and lower sewing a needle, exposing the sclera preferably not more than 3mm (onset of pterygium meat, no stitches), taking kenacort-A2 ~ 4mg injection in pterygium root of surgery, antibiotic ointment dressing painted eyes, began to drop anti-inflammatory eye drops after surgery the next day, 5 stitches, 4 weeks after repeated injection of pterygium root 1. 1.4 evaluation standard problem of postoperative recurrence of pterygium, Wang Qiaoqin [1] that were observed after 2 to 3 months, still no recurrence of the possibility of recurrence that has been very small. I believe that 3 months after the Department of pterygium body atrophy, smooth, clear the wound, blood vessels break, pterygium head, the cure is no longer alien to the cornea; still in the corneal pterygium, body no congestion is effective; treatment pterygium meat is not shrinking, body and continue to invade the cornea congestive invalid. 1.5 treatment results were followed up for 2 years in all cases, the result of the onset of resting pterygium pterygium and the best treatment, no recurrence. For 507 of pterygium recurrence 2; recurrence of pterygium recurrence 4. 2 discussions pterygium is a common disease of eye, most patients feel the impact of aesthetics and the requirements of early treatment, recurrence rate as previous surgery, doctors were helpless to pterygium only pupil, affecting visual acuity before surgery. This is not true, for the pathogenesis of pterygium, I point in each hospital to do further study, from the epidemiological point of view [2], is still considered to be inflammation and degeneration. Histologically [3], Chen Zuji and other studies also found that in the eye, epithelial cells and Bowman membrane where a large number of fibroblasts between the family together. We found these hematoxylin nuclear doctrinal, and some eosin stained light particles, which are not stereotypes, and some areas around the collagen fibers in red, the structure is unclear, increasing the height of endothelial cells. The strong activity of particulate matter, facilitate the occurrence of abnormal elastic fibers or collagen fibers edema, hypertrophic degeneration. Can be seen from the anatomy, multiple pterygium's spot as the starting place to blepharophimosis, that spot in the palpebral fissure occurred at the island-shaped corneal infiltration, corneal sent to the Ministry of new blood vessels form a rich vascular network, extension elastic layer of the cornea occurred in the degree of change, so it became a good base for the growth of pterygium, according to this characteristic, to still the inflammatory degeneration. Made in the initial period of pterygium and the resting stage, the eruption of new blood vessels and vascular wall sclerosis just shrinking stage, surgery and drug treatment given, the cure rate can reach 100%. For the duration and other pterygium after surgery requires repeated treatments for 2 times in order to effectively control the inflammation and prevent recurrence, improve the cure rate. After two of the recurrence of pterygium 3 eyes, the cure rate of more than 5 ‰. Found in the statistics of our hospital, patients with multiple chronic stimulation by inflammatory lesions of the conjunctiva repeated treatment, KemelGernndo that it is the nature of inflammation.
