62 people (124 eyes) age from 21 to 49 (35 males, 27 females) are divided into 2 groups: in the first group 18 objects (36 eyes) with conjunctivitis, in the second group 44 objects (88 eyes) without conjunctivitis. All objects have taken Shirmer test (I and II), BUT, test of Rose-bengal and fluorescein. All are applied with Sanlein (Santen Agency). And those tests are measured after 1 and 3 months. Results: The Shirmer I and II, and BUT in the group 2 is higher than in the group 1, though BUT of both groups is at under normal level. Test of Rose-bengal 1 and 2 in group 1 is higher than in group 2. The intergrity of epithelial cells is also changed. Tear secretion of both groups at normal physiological level. Sanlein has good effect, partially improves tear indicator

Object: workers of Cua Lo, Ben Thuy port, mechanics enterprise, work enterprise and port’s office. Method: intersect description. Result: About working environment, there are 18,4% samples not get hygiene standard, 53,2% dust samples over hygiene standard ( 2 to 12 times). 71,0% worker are working in having dust environtment. 31,2% use glass and 22% use eye drug when working. Eye disease status: 90,0% have symptom in eye, 69,6% catch eye disease. Preventive treatment has signigicant result

In May 1999, an investigation was performed in Bac Ninh province – Tien Son district, addressing to 270 households (among them 263 with ill persons) in order to assess the use of health services. Results show that the services of private sector are more preferred (61.99%) than those of commune health station (23.19%) and of the state hospital (6.85%).

The eye dry syndrome is increasingly and a difficult problem in the ophthalmology. There were about 15% of people over 60 years experienced the eye dry of which 10% must be treated. This disease usually considered because initial mild symptoms. However, these symptoms can lead eye burn that can not be treated. The superficial corneitis with severe pain and vision loss occurred subsequently. The corneal and conjunctival surface usually protected from chemical component, mechanical agent, microbial and virus and film of aqueous humor as a first barrier.

Doctors operated 29 patients (35 eyes) with cicatricial entropion of eyelid, among them there are 15 eyes (42.85%) with complication of burn; 14 eyes (40%) with complication of Stevens-Johnson syndrome and 6 eyes (17.15%) with recurrent entropion. The follow-up ranged from 1-6 months. Results: of the 35 eyes operated, 27 eyes (77.14%) were successfully treated (the eyelid was corrected); only 1 eye (5.72%) needed a repeat operation. This study indicated that mucous membrane graft is an effective treatment for patient with cicatricial entropion of eyelid. But, these are the first results. Further studies are necessary to confirm the long time effectiveness of method.

The purpose of this study was to evaluate the efficacy of conjunctival autograft with single intraoperative application of MMC 0.04% within 3 minutes in primary and recurrent pterygium and to compare this method with other’s. Sixty three patients (68 eyes: 50 eyes with primary and 18 eyes with recurrent pterygium) underwent pterygium excision with conjunctival autograft and single application of MMC 0.045/3 minutes. Patients were followed from 3 to 12 months after operation. Results: recurent rate of 1.96% (1 eye) was observed in the group of recurrent pterygium. There were 2 cases of superficial punctuate keratitis. Conclusion: this study indicates that intraoperative administration of a single dose of 0.04% MMC with conjunctival autograf is an effective treatment for prevention of recurrence of pterygium

In this prospective randomized controlled study, a total of 70 patients (76 eyes) diagnosed with acquired nasolacrimal duct obstruction operated by DCR with intraoperative mitomycin C 0.4mg/ml appication to the osteotomy site for 3 minutes. The results of the DRC surgeries were evaluated by objective findings such as irrigation, height of tear meniscuc, ostium size and subjective symptoms. Among the 76 eyes, 96% of patiets remained total symptoms free after 6 months of follow up. Mean ostium size 2.861 (0,785mm. There were no complications such as abnormal nasal bleeding, mucosal necrosis or infection

The authors evaluated the efficacy of cromal in the treatment of allergic conjunctivitis. Method: 30 patients (28 males, 12 females) were assigned in two groups: group1:14 patients with seasonal allergic conjuntivitis; group2: 24 patients with vernal keratoconjuntivitis. In a double masked random design, the patients of each group were received cromal eye drops or NaCl 0.9%. Results: eyes treated with cromal eye drops in two groups showed an amelioration of the sign and symptoms of disease compared with eyes received only NaCl 0.9%. Conclusion: cromal seems to be effective in treatment of allergy.

According to the results of an investigation on 270 households in May 1999 carried out in Tien Son district, Bac Ninh province, 56 (20.79%) purchasing households came to commune health centre, 195 (72.22%) came to private clinic, 8 (2.96%) came to public pharmacy and 11 (4.03%) came to private pharmacy. Quality of the drug, easiness to access, reasonable price, good counseling... are the favorable factors to promote the purchaser's choice

The tear production of 192 eyes was evaluated by shirmer I and 171 eyes were evaluated by shirmer II among 106 patients (male: 30). The results showed that the average value of total tear production in elderly was 8.7±6.6mm and average value of basic tear production was 6.1±4.3 mm. There was no difference of tear production was reduced with increased ages
