Electric and magnetic form factors of neutron are calculated via electron-deuteron scattering at 1.511 ～5.507 GeV energy using SLAC group data. Our results show that the neutron electric form factor is not equal to zero;rather it has a small value, indicating that in spite of the fact that total charge is almost neutral, there is a nonuniformcharge distribution within the neutron, and that magnetic form factor follows the dipole fit.

Using the most recent phase shift data for pp,nn,and np elastic scattering for different states (l=0,1,...) in the energy range of i meV to 350 meV,the charge dependency of the strong nuclear force is *** results indicate that although the charge independency holds in most of the energy range,such charge independency is broken in the particular energy range of 120 meV to 200 meV for all partial wave states considered here.

Aims/background: To analyse the effectiveness and safety of cyclodiode treatment in eyes with silicone oil-related raised intraocular pressure (IOP) and to correlate the results with clinical features of treated eyes. methods: Retrospective review of case notes of all eyes that underwent cyclodiode treatment following injection of silicone oil at moorfields Eye Hospital between April 1993 and January 2003 and were followed up for at least 1 year. Results: In all, 38 patients were followed up for between 13 and 113 months. Totally, 17 had silicone oil in situ at the time of first treatment. The mean pretreatment IOP was 31.4 mmHg (SD 10.9), reducing to 18.6 mmHg (SD 8.6) at 1 year and to 13.9 mmHg (SD 8.4) at the final follow-up visit (P ment, 28 (73.7% ) patients were on two or more topical medications. This was reduced to 18 (47.4% ) patients (P=0.013) at 1 year and 13 (34.2% ) patients (P=0.0007) at final follow-up. Use of oral acetazolamide for glaucoma was reduced from 16 (42.1% ) patients precyclodiode to five (13.2% ) patients at 1 year (P=0.0034) and three (7.9% )- patients at the final visit (P=0.001). Four patients (10.5% ) at 1 year and five patients (13.2% ) at the final visit had hypotony (defined as IOP of less than 5mmHg). One patient had enucleation 75 months following first cyclodiode treatment. Conclusion: Diode laser photocoagulation can successfully control silicone oil-induced raised intraocular pressure where medical treatment fails. Reduction of IOP appears to be maintained long term.

Background: Central retinal vein occlusion (CRVO) is a common retinal vascular disorder and a leading cause of visual loss. It is thought to arise from vascul ar obstruction at the level of the lamina cribrosa. The purpose of the study rep orted here was to evaluate the potential benefit of radial optic neurotomy (ROn) and determine its effect on foveal thickness and macular volume in patients wit h CRVO. methods: We conducted a prospective pilot study of ten patients with CRV O. Visual acuity (VA) score measured with the Early Treatment Diabetic Retinopat hy Study chart and the corresponding Snellen equivalent were assessed before and 6 months after surgery. Colour fundus photography, fluorescein angiography (FA) and optical coherence tomography (OCT) were carried out before and at 2, 6, 12 and 24 weeks after surgery. Foveal thickness and macular volumes were assessed u sing OCT. Results: Visible reperfusion was observed in four of the ten patients at the time of surgery. VA score improved in eight of the ten patients from a me dian score of 11.50 (range 0-68) to a median score of 35.00 (range 3-79). macu lar volumes decreased in six of seven patients from a median of 4.99mm3(range 2. 68-6.77) to amedian of 3.11mm3 (range 1.11-5.02). Foveal thickness decreased i n six of seven patients from a median of 596.50 μm (range 338.50-745.50) to a median of 330.50 μm (range 118-634.50). Six of ten patients developed a chorio retinal venous anastomosis. macular oedema on OCT persisted in six of ten patien ts. Conclusions: We observed an improvement in VA score and a corresponding redu ction in foveal thickness and macular volume following ROn, but macular oedema p ersisted in 60%of patients. Whilst op timisation of patient selection criteria remains a challenge, this pilot study suggests that ROn has a beneficial effect on VA in patients presenting with CRV O.

To evaluate the functional and anatomical results of macular hole surgery and to explore its effect on patients’Health-Related Quality Of Life (HR-QOL) and to investigate the associations between self-reported HR-QOL and conventional measures of visual function. Case series. The national Eye Institute 25-Item V isual Function Questionnaire (VFQ-25) and the 36-Item Short-Form Health Surve y (SF-36) were self-administered by 30 patients before and 4 months after macu lar hole surgery. Preoperative, intraoperative, and postoperative clinical data were collected including visual acuity, contrast sensitivity, and metamorphopsia . multi-item scales rating different aspects of HR-QOL were compared before an d after surgery, and their correlation with traditional methods of outcome evalu ation was analyzed. macular hole closure was achieved in 26 patients (87%). mea n LogmAR visual acuity improved by 6±10 letters for distance and 7 ±12 letters for near. metamorphopsia was reduced by a mean of 35±70 squares on Amsler char t, and Pelli-Robson contrast sensitivity decreased by a mean of -0.09 ±0.3 lo g units postoperatively. The VFQ-25 composite score as well as scale scores ass ociated with general vision, near vision, vision-related mental health, and rol e difficulties were significantly improved (P macular hole. Conversely out of the eight SF-36 health concepts, limitation i n usual role activities because of emotional problems was the only one that sign ificantly improved postoperatively. Both baseline and postoperative best-correc ted visual acuity significantly correlated with most of the VFQ subscale scores before and after surgery, respectively. In this case-se-ries, macular hole sur gery appears to have a beneficial effect on patients’subjective perception of v isual function. The use of vision-targeted health status questionnaires in conj unction with detailed clinical examination provides a more comprehensive overvie w of indivi
