30 eyes of 28 patients (18 female, 10 male, aged 45-75) of primary glaucoma (25 eyes with closed angle glaucoma and 5 eyes with opened angle glaucoma) at the National Institute of Ophtalmology were operated. No complications occurred. In postoperative period, there were 4 eyes with low interocular pressure and very shallow vestibule. In discharge, 46.6% eyes got a visual acuity of 4/10 to >6/10, and 13.3% <1/10, interocular pressure was regulated with X=18.20.8 mmHg. All operated eyes had scars. After 1 year, acuity visual had been re-examined on 28 eyes, no change of visual acuity, vision field and scars. Interoculary pressure was normal level of X=19.61.2 mmHg

On 108 eyes of 54 patients (19 males, 35 females, aged 45-75) thickness of cornea was measured. 40 patients with 1 eye acute glaucoma and the 2nd eye has not glaucoma (potential angle closure), 14 other patients with both 2 eyes of high ocular pressure (entire closure of vertibular angle). Results showed that the centre corneal thickness got an important change in angle closure glaucoma, it had a lineary relation with ocular pressure. In the crisis of acute angle closure glaucoma, corneal thickness accounted for x = 0.5730.053 mm and the crisis of potential angle closure glaucoma x = 0.5310.031 mm. With an increase of pressure of 1 mmHg, corneal thickness increases by 0.038 mm

The study carries on 48 patients opered glaucoma by technique phacoemulsification at central eye institute. If at tense capsulotomy is complete, all tenses later are very advantage. This technique used source of cold-lean light of endophthalmen lamp to tear one central small capsule, then tear rearward when dispose cataract artificial. It shoud combine blue reagent to tear capsule more advantage. For cases that it observes difficult, can use head-straw to clear, thence can pump mucous substance under capsule of cataract to fill out capsule and tear following. Technique phacoemulsification can apply for eyes with white cataract, bring high vision for patients but it is necessary to have some technique support as tense capsulotomy and crush nuclear when it is sclerosis

The author measured the thick of centre-cornea for 42 patients angle closure glaucoma and 16 patients open angle glaucoma. The results: Centre-cornea in angle closure glaucoma and high IOP is clearly thicker than open angle glaucoma and than angle closure glaucoma potential. In the angle closure glaucoma, the thick of centre-cornea decrease and come to normal after the operation 3 months. Thick of centre-cornea in open angle glaucoma high IOP, potential and Vietnamese normal are equivalent. In patient open angle glaucoma, the thick of centre-cornea is not changing after the trabeculectomy
