AIM: To investigate the effect and safety of laser peripheral iridoplasty combined with iridectomy in the unmanageable acute angle - closure glaucoma by medication.
METHODS:Totally 19 cases (21 eyes) with acute angle-closure glaucoma, including 15 cases ( 17 eyes ) with primary glaucoma and 4 cases (4 eyes) with intumescent cataract - induced glaucoma, were recruited into the study. The intraocular pressure ( IOP ) of all cases were still >21mmHg after 24h drug treatment, and then were treated by laser peripheral iridoplasty combined with iridectomy. The visual accurity, IOP, cornea, peripheral anterior chamber depth, anterior chamber angle and complications were observed at 24h after the surgery.
RESULTS:The mean IOP of all cases was reduced from 53. 09±11. 01mmHg before the surgery to 14. 98±4. 21mmHg at 24h after the treatment, with significant statistical difference ( P< 0. 01 ). The visual acurity of all cases increased in different degrees from handle move to 0. 3 to 0-1-1. 0 at 24h after the treatment. In all cases, cornea edema reduced or cleared up, peripheral anterior chamber depth increased, and anterior chamber angle reopened in different degrees. Complications included iris hemorrhage in 11 eyes (52. 4%), mild iritis in 21 eyes (100%). No cornea burn was encountered.
CONCLUSION: Laser peripheral iridoplasty combined with iridectomy is an effective and safe method for the treatment of the unmanageable acute angle - closure glaucoma by medication.

Objective To discuss the imaging representations and its clinical significance of acute indigitation in infants.Methods The imaging representations including CT,ultrasonography stand abdominal plain film and gas clysters of indigitation comfirmed by operation in 58 infants were analysed.Results (1)Of 58 cases,33 were ileum-colon and ileum-caecal type,25 were ileum-ileum-colon,ilem-cecal-colon and ileum-colon-colon type;(2)The main imaging representations were as following:gas decreased in colon of small intestine (12 cases),inflation in intestine and incomplete ileus (18 cases),ileus of small intestine(17 cases),no abnormity on stand abdominal plain film (8 cases).Gas clyster showed the "goblet sign" and masses (28 cases).The sign of targed rings was seen on ultrasonography(3 cases).The layered homocentric round tumors showed by CT (1 case).Conclusion The imaging representations of acute indigitation in infants are typical,which are significant for the diagnosis.

AIM: To evaluate the physiologic change of retinal thickness during pregnancy.
METHODS:Forty cases ( 80 eyes ) were included two groups:40 eyes ( 20 cases ) in healthy pregnant women group (including in the second and last trimester), and 40 eyes (20 cases) in healthy nonpregnant women group ( control group ) . The macular volume, average thickness, central subfield thickness and retinal thickness of other parafoveal areas were measured by optical coherence tomography scan.
RESULTS: The macular volume was 10. 06±0. 41mm3 and 9. 87±0. 30mm3 in healthy pregnant women group and control group respectively. The average thickness was 279. 43±10. 86μm and 274. 25±8. 07μm in healthy pregnant women group and control group respectively. The central subfield thickness was 235. 15±15. 05μm and 233. 00±15. 81μm in healthy pregnant women group and control group espectively. Statistically significant difference was found in macular volume and average thickness (P<0. 05). The retinal thickness of 8 parafoveal areas in healthy pregnant women group increased comparing with control group, but statistical significance was only found in superior-outer area and inferior-outer area(P<0. 05). OCT images of all cases were normal.
CONCLUSION:The macular retinal thickness increases during pregnancy in the second and last trimester. The physiologic change of retinal thickness should be considered when evaluating pathologic retinal disease of pregnant women.

AIM: to assess the effectiveness of a combined procedure ( pars plana vitrectomy with temporary keratoprosthesis, vitreoretinal surgery, and penetrating keratoplasty). in the complicated cases and the risk factors for the surgical failure.METHODS: Restrospectively reviewed charts of patients who underwent penetrating keratoplasty in combination with vitreoretinal surgery between 1990 and 2005, with a follow-up of 3mo to 9a. Analysis was focused on ocular history, indications for surgery, visual acuity (VA), anatomic results, and complications.RESULTS: 18 eyes had light perception or VA of hand motions only. The best-corrected VA improved during the first 3mo, increased in 72.2% of all eyes, remained unchanged in 27.78%, and no decreased. In 3 of 18 eyes (16.67%), VA was better than finger counting and hand motions, and nine eyes(50%) showed useful vision (0.05) postoperatively. 10 eyes showed a clear corneal graft (55.56%). 2 eyes needs the second keratoplasty, Bullous corneal edema was evident in 3 eyes, band keratopathy was evident in a 3 eyes. 10 patients were observed for more than 2a;6 had a clear graft (60%). Two eyes (11.11%) had silicone oil-corneal endothelium contact and all of these grafts failed.CONCLUSION: Although the functional outcome of a combined procedure is limited by primary and secondary tissue destruction, preserving ambulatory vision is possible and thus improves the quality of life, at least in patients with single remaining eyes.

Objective To investigate the iodine nutritional status of children aged 8 to 10 in both costal and non-costal areas of Rizhao city Shandong province,and provide a basis for scientific supplementation of iodine.Methods In 2009 and 2010,townships of Lanshan and Donggang were chosen as survey points which situated close to the coast,the counties of Wulian and Juxian that were more than 50 kilometers away from the coast were selected as controls.The iodine concentration of drinking water in every village and water supply point was determined.At the county level,5 to 9 towns were selected according to their sub-area positions of east,west,south,north and center,4 villages were selected in each chosen township,8 - 15 households were selected in each chosen village,edible salt from the households was collected; 5 primary schools were selected in each chosen township,60 students aged 8 - 10 were selected to take thyroid examination in each chosen school.Twenty copies of urine samples were collected from the 60 students to detect the iodine concentration.Iodine in drinking water was tested by cerous sulfate catalytic spectrophotometry,in iodized salt by direct titration,in urine by arsenic-cerium contact method,and thyroids were examined by palpation.Results Totally 3483 copies of drinking water samples,1164 copies of edible salt samples,and 476 copies of urine samples were tested,and a total of 1200 children aged 8 to 10 were investigated; and the ratio of water iodine frequency distribution ≤ 10 μg/L (in costal and non-costal area) accounted for 90.03％ ( 1011/1123 ) and 91.10％ (2150/2360),respectively,the medians of water iodine were 5.6 and 4.2 μg/L,respectively; the iodine medians of edible salt were 29.03 and 29.99 mg/kg,respectively; the consumption rates of qualified iodized salt were 96.77％ (569/588) and 97.05％ (559/576),respectively; total goiter rates were 1.17％(7/600) and 1.33％(8/600),respectively; the medians of urinary iodine were 144.05 and 159.15 μg/L,respectively; the percentages of urinary iodine that bellow 100 μg/L were 26.58％ (63/237) and 22.59％ (54/239),respectively; between 100 - 300 μg/L were 66.75％ (158/237) and 64.02％ (153/239),respectively;above 300μg/L were 6.75％ (16/237)and13.39％ (32/239),respectively.ConclusionsThe costal of Rizhao is an iodine deficient area.The current popularity of household's consumption of qualified iodized salt is suitable.The levels of iodine nutrition of children aged 8 to 10 is appropriate,which met the national standard of elimination of iodine deficiency disorders (IDD).There is no iodine excess.There are no significant differences in levels of iodine nutrition between costal and non-costal areas on the premise that the same iodized salt is supplied in both the areas,and there is no need to make differentiated supply of iodized salt.
