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

To evaluate clinical availability of the Dark Room Prone-position Test (DRPT), which is one of the provocative tests of angle-closure glaucoma, this study was carried out. Twenty nine patients (43 eyes) with primary angle-closure glaucoma (PACG) were enrolled, and seventeen primary open angle glaucoma (POAG) patients (34 eyes) arld fourty one normal persons (82 eyes) were used as control group. After DRPT, P ACG showed statistically significant intraocu lar pressure (IOP) rise of 6.3 +/- 6.82mmHg as compared with group of POAG or normal 2.0 +/- 2.04mmHg and 1.4 +/- 1.47mmHg, respectively (p<0.05). Fifteen eyes among 43eyes (34.9%) of PACG showed DRPT positive defined as over 7mmHg rise after DRPT, and the final IOP of DRPT over 21mmHg showed significant DRPT positive (43.5%) than that of under 20mmHg (0.00%) (p<0.05). Glaucomatous attack was more occurred 1.9 times in DRPT postive group than in DRPT negative one.

PURPOSE: To report the difference between the postoperative spherical equivalent (SE) and predictive refraction in patients with cataract and primary angle-closure glaucoma (PACG) following cataract operation. METHODS: (1) This study involved 60 eyes who underwent cataract surgery due to PACG and cataract, and 36 eyes who underwent surgery due to cataract only. We measured the manifest refraction postoperatively for comparision to the target power. (2) The axial length (AL) was measured by the different modes of A-scans(phakic, aphackic modes) in the 38 eyes with cataract. (3) The difference was calculated according to the three IOL power calculation formulas for the 60 eyes who had cataract surgery for coexisting PACG and cataract. RESULTS: The difference between postoperative SE and predictive refraction was -0.61+/-0.91D in the PACG with cataract and +0.08+/-0.43D in eyes with cataract only. There was no difference according to the IOL power calculation formulas or the different modes observed in the measurement of AL. A greater difference was seen in eyes with a short AL and an unmeasurable ACD. CONCLUSIONS: The difference between postoperative SE and predictive refraction increased in eyes with the PACG and cataract over those with cataract only. For cataract operation in these eyes, the choice of a lower power IOL (about 0.5D) may be helpful to reduce this difference, especially for eyes with a short AL (less than 24 mm) and an unmeasurable ACD.

PURPOSE: To compare the characteristics of visual field defect in primary open-angle glaucoma (HTG), normal-tension glaucoma (NTG) and primary angle-closure glaucoma (ACG). METHODS: We investigated the visual field defect of HTG (n=75), NTG (n=58), ACG (n=150) patients from March 2000 to November 2002. We compared the severity and asymmetry of the visual field defect in both eyes, the asymmetry of a more severely affected hemifield between both eyes, and the frequency of an early visual field defect with equivalently affected superior and inferior hemifield. RESULTS: The visual field defect was the severest in HTG, and the mildest in ACG. Asymmetry in severity of visual field defect between both eyes was the severest in HTG, and the mildest in NTG. The asymmetry of the affected hemifield between both eyes in terms of superior and inferior hemifields was most frequent in NTG. The frequency of the early visual field defect with equivalently affected superior and inferior hemifields occured mostly in NTG. ACG without an attack history had a more severe visual field defect than that with an attack history. CONCLUSIONS: The topographical pattern of the visual field defect was different in HTG, NTG, and ACG. There may be different pathophysiological mechanisms in the three types of primary glaucoma.

To find the factors that affect on the success rate of the trabeculectomy, we investigated 208 eyes of 158 patients with various types of glaucoma which had undergone trabeculectomy. The patients were followed up at least 3 month postoperatively. The criteria of success was maintenance of postoperative IOP below 21 mmHg. The total success rate was 89.4%. In young patients, the success rate was lower than that of older ones. The success rate of open angle glaucoma, acute angle closure glaucoma and chronic angle closure glaucoma were higher than that of congenital glaucoma and secondary glaucoma. Recently performed operation demonstrated higher success rate. The type of conjunctival flap, scleral flap and use of 5-fluorouracil were independent factors that affect on the success rate.

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

OBJECTIVETo assess the agreement between gonioscopy and ultrasound biomicroscopy (UBM) in detecting angle closure in Chinese patients with shallow anterior chamber.

METHODSAn observational comparative study of the two different examination methods was conducted. Patients with normal intraocular pressure and temporal peripheral anterior chamber depth less than a quarter of corneal thickness based on slit lamp examination were included in this study from December 2007 to May 2009 in the outpatient clinic of First Hospital of Tsinghua University. Gonioscopy was performed with a Goldman goniolens in dark room first and followed by full beam light and indentation. If the filtering trabecular meshwork was invisible or any peripheral anterior synechia was found, that quadrant of the angle was considered closed. UBM was first undertaken in a darkened room then repeated with normal room lighting. If iridotrabecular apposition was showed, that quadrant of the angle was considered closed. The status of angle closure of each quadrant with different methods was recorded.

RESULTS85 eyes of 46 patients were included in this study. The agreement between gonioscopy and UBM was poor (Κ<0.4) with Kappa analysis in both dark and light conditions in each quadrant. The accordance of agreement between gonioscopy and UBM was hardly affected by age or sex, while in dark condition, eyes with deeper anterior chamber (P=0.005) or plateau iris configuration tended to produce different results (P=0.075) in the 2 methods.

CONCLUSIONGonioscopy and UBM are both indispensable methods for detecting angle closure, neither can completely replace the other.

A case of iridoschisis was reported. The 67-year-old man showed a typical iridoschisis with angle closure glaucoma in his left eye. The intraocular pressure was 30mmHg and grade I narrow angle was noted. Intraocular pressure was lowered to 16mmHg by beta blocker instillation only.
