AIMTo determine the effectiveness of pharmacological and interventional treatment of hypotony and flat anterior chamber (FAC) resulting from glaucoma filtration *** retrospectively examined the medical records of fifty-two trabeculectomy patients (52 eyes) who developed postoperative hypotony and FAC. The management and associated complications of hypotony, changing intraocular pressure (IOP) and best corrected visual acuity (BCVA) were *** the 52 patients with hypotony, 29 (56%) had a grade 1 FAC, 21 (40%) had a grade 2 FAC, and only 2 had a grade 3 FAC. There was no significant difference between the mean preoperative IOP and the mean IOP at three and six months after surgery. Thirteen eyes (25%) required antiglaucomatous medication three months after surgery. The mean BCVA at 6mo after surgery was significantly reduced as compared with the mean preoperative *** and FAC following trabeculectomy are associated with troublesome complications that require pharmacological and/or surgical treatment. Thus, close follow-up is essential for affected patients.

AIM： To compare three initial monthly intravitreal ranibizumab（IVR） injections followed by pro re nata（PRN） dosing with one initial monthly IVR injections followed by PRN dosing for macular edema（ME） secondary to branch retinal vein occlusion（BRVO）.METHODS： Forty-two eyes of 42 patients who had IVR injections for BRVO were retrospectively studied. Eighteen eyes received 1 initial IVR injection（1＋PRN group） and 24 eyes received 3 monthly IVR injections（3＋PRN）. At 1, 3, 6 and 12mo; spectral-domain optical coherence tomography（SD-OCT） was performed. Central macular thickness（CMT）, the integrity of the external limiting membrane（ELM）, the presence of subretinal fluid, cyst size, the presence of inner segment/outer segment（IS/OS） defect were ***： At baseline the mean CMT was 521.3±153.2 μm in the 3＋PRN group while it was 438.1±162.4 μm in 1＋PRN group. At the final visit, mean CMT was 278.3±87.8 μm in the 3＋PRN group and 285.2±74.2 μm in the 1＋PRN group（P=0.079）. The changes in CMT over the entire study period were also comparable in both groups（243±160 μm in the 3＋PRN group, and 152.9±175.3 μm in the 1＋PRN group; P=0.090）. At baseline, best-corrected visual acuity（BCVA） was 0.92±0.60 logarithm of the minimal angle of resolution（logMAR） in the 3＋PRN group, while it was 0.72±0.46 logMAR in the 1＋PRN group. Final BCVA was 0.42±0.55 logMAR in the 3＋PRN group and 0.38±0.50 logMAR in the 1＋PRN group（P=0.979）. Additionally, the BCVA changes from baseline to final visit were not significantly different（-0.50±0.45 logMAR in the 3＋PRN group, and-0.33±0.39 logMAR in the 1＋PRN group; P=0.255）.CONCLUSION： No significant differences in the anatomical or functional results are found between 3＋PRN and 1＋PRN regimens in the patients receiving ranibizumab for ME secondary to BRVO. Intact IS/OS and baseline BCVA are good predictor of the visual gain, while baseline CMT is a good predictor of the anatomical gain.

The effects of electromagnetic waves in drying processes of solid materials are investigated theoretically and experimentally. Modified model of mass transfer being constituted by the effect of electromagnetic waves which have different frequency has been obtained. Modeling of the drying process with a two-port electric circuit for the determination of diffusion coefficients is designed. The frequency limits of electromagnetic wave which will be able to hasten the drying process are determined. The effects of the electromagnetic wave in the potato slice drying process by the influence of different frequencies and temperatures are experimentally examined. The results obtained are compared with theoretical calculations. Moisture concentration curves in drying process have been commented by drawing. Theoretical and experimental results which have been obtained are identified as a well adaptation.

AIM: To assess lung parenchymal changes in ankylosing spondylitis (AS) using high resolution computed tomography (HRCT). METHODS: We included 78 AS patients whose average age was 33.87 (18-56) years with a ratio of 53 males to 25 females who were followed up for 3.88 (1-22) years on average. neumonia and tuberculosis were excluded. In a detailed examination of lung HRCT findings, we investigated the presence of parenchymal micronodules,parenchymal bands, subpleural bands, interlobular and intralobular septal thickening, irregularity of interfaces,ground glass opacity, consolidation, mosaic pattern,bronchial wall thickening, bronchial dilatation, tracheal dilatation, pleural thickening, emphysema, thoracic cage asymmetry, honeycomb appearance, structural distortion, apical fibrosis and other additional ***: In detailed HRCT evaluations, lung parenchymal changes were found in 46 (59%) of all patients. We found parenchymal bands in 21 (27%) cases, interlobular septal thickening in 9 (12%), emphysema in 9 (12%), apical fibrosis in 8 (10%), ground-glass opacities in 7 (9%), parenchymal micronodules in 5 (6%), irregularity in interfaces in 3 (4%), bronchial dilatation in 3 (4%), mosaic pattern in 2 (3%), pleural thickening in 2 (3%), consolidation in 1 (1%), bronchial wall thick ening in 1 (1%) and a subpleural band in 1 (1%) case. Furthermore, we detected subsegmental atelectasis in 2 patients and a cavitary lesion in 1 patient. CONCLUSION: Our study had the highest number of AS cases of all previous studies in evaluating lung paren chymal changes. The rate of lung parenchymal changes was slightly lower than that reported in recent literature.
