AIM: To compare two different anti-vascular endothelial growth factor(anti-VEGF) treatment regimens'-a priori pro re nata(PRN) and PRN regimen following^(th)e loading phaseanatomical and functional results in neovascular agerelated macular degeneration(n AMD) patients. METHODS: Totally 544 n AMD patients followed and treated with aflibercept(n=135) and ranibizumab(n=409)at 9 different centers between 2013 and 2015 were enrolled into^(th)is retrospective multicenter study. Patients with initial best corrected visual acuity(BCVA) interval of 1.3-0.3(log MAR) and a minimum follow-up of 12 mo were included. Patients under two different regimens-a priori pro re nata(1+PRN) or 3 consecutive intravitreal injections followed by a PRN regimen(3+PRN)-were compared in BCVA at 3^(th), 6^(th) and 12^(th) months, and in central macular^(th)ickness(CMT) at 6^(th) and 12^(th) months. The total study group, intravitreal ranibizumab(IVR) and intravitreal aflibercept(IVA) groups were evaluated separately. RESULTS: The mean CMT decreased in^(th)e 1+PRN(n=101) regimen from 407 to 358 and 340 μm and in^(th)e 3+PRN(n=443) group from 398 to 318 and finally to 310 μm at months 6 and 12, respectively. Anatomically,^(th)e CMT reduction at 6^(th) month(48.5 vs 76.4;P<0.05) was statistically significant in favor of 3+PRN group. BCVA changed in 1+PRN group from 0.77 to 0.78, 0.75 and 0.75;in 3+PRN group from 0.81 to 0.69, 0.72, and 0.76 at months 3, 6, and 12, respectively. Visual gain was statistically better in 3+PRN group at 3^(th) month(-0.01 vs 0.12;P<0.001). In IVR group, CMT reduction was in greater in 3+PRN at 6^(th)(44 vs 72) and 12^(th) month(61 vs 84), but statistically insignificant. The 3+PRN group revealed statistically better visual results at 3^(th) month(-0.02 vs 0.11, P<0.05). In IVA group, although statistically insignificant, CMT reduction(61 vs 89, 6^(th) month;85 vs 97, 12^(th) month) and visual gain(0.02 vs 0.16;0.02 vs 0.14;0.05 vs 0.11) was found in favor of 3+PRN group

Ag-In intermetallic alloys were produced by using vacuum arc furnace. Differential Scanning Calorimetry(DSC) and Energy Dispersive X-Ray Spectrometry(EDX) were used to determine the thermal properties and chemical composition of the phases respectively. Microhardness values of Ag-In intermetallics were calculated with Vickers hardness measurement method. According to the experimental results, Ag-34 wt%In intermetallic system generated the best results of energy saving and storage compared to other intermetallic systems. Also from the microhardness results, it was observed that intermetallic alloys were harder than pure silver and Ag-26 wt%In system had the highest microhardness value with 143.45 kg/mm^(2).

AIM:To investigate the effects of exogenous testosterone treatment on the choroidal parameters in patients with androgen ***:Right eyes of 24 patients with androgen deficiency and 31 healthy volunteers were included in the *** eyes were scanned for subfoveal choroidal thickness(SFCT),choroidal vascularity index(CVI),choroidstromal area(C-SA),choroid-luminal area(C-LA),choroidstromal to luminal area ratio(CSLR),and the choroidal parameters within central 1500μm of the macula(CVI1500,C-LA1500,C-SA1500,and CSLR1500)by enhanced-depth imaging optical coherence tomography(EDI-OCT)at baseline,6th and 18th weeks of the exogenous testosterone ***:The mean SFCT values of the androgen deficient groups and healthy controls were 307.7±27.0 and 303.2±37.2μm(P=0.8).However,CVI,C-SA,CSLR,CVI1500,C-LA1500,and CSLR1500 were significantly different between the groups(all P0.05).However,CVI1500 and LA1500 significantly increased at the end of the follow-up period(P<0.001).CONCLUSION:CVI is lower in androgen-deficient patients than in healthy *** alterations in the choroid during the testosterone peak are transient in the treatment of patients with androgen ***,the increase in CVI within the central 1500μm of the macula persists even after 4mo.
