Purpose: t.e main object.ve was t. analyze t.e relat.onship bet.een maximum cup dept. (MCD), mean defect.(MD), cent.al corneal t.ickness (CCt., age and disc area, in pat.ent. wit. ocular hypert.nsion (OHt. and primary open angle glaucoma (POAG). Met.ods: Cross-sect.onal st.dy of pat.ent. diagnosed wit. OHt.and POAG. Visual fields were obt.ined using an Oct.pus 300 analyzer, t.P st.at.gy. MCD and disc area were obt.ined using a Heidelberg Ret.na t.mograph. Result.: t.e st.dy sample comprised 234 eyes of 143 pat.ent., 91 women and 52 men, mean age 63.55 years (SD 10.49). Mean values were: MCD 0.52 mm (SD 0.27), MD 2.78 dB (SD 5.02), CCt.543.5 μm (SD 36.63), IOP 16.73 mmHg (SD 2.93), and disc area 2.01 mm2 (SD 0.39). A significant.correlat.on was observed bet.een MCD and age in pat.ent. under 60 years, bet.een MCD and disc area, and bet.een MD and disc area. Conclusions: Our st.dy showed a correlat.on bet.een MCD and age which was significant.in pat.ent. under 60 years of age, bet.een MCD and disc area and bet.een MD and disc area, suggest.ng t.at.t.e larger t.e disc area, t.e great.r t.e MCD and t.e MD in pat.ent. wit. OHt.and POAG.

Flavor violat.ng Higgs signals, such as t.e t.p FCNC decay t.ch0 and t.e LFV Higgs decay h0→τμ, have been st.died at.t.e LHC. t.ese signals can arise wit.in t.e general t.o-Higgs Doublet.Model （t.DM）, where each Higgs doublet.couples t. all fermion t.pes t.rough Yukawa mat.ices Yf 1 and Y f2 . t.e Yukawa mat.ices can be assumed t. have t.e same form or t.ey could have different.st.uct.res. In t.is paper we st.dy t.e case when bot. Yf1 and Y f2 have complet.ly different.forms, but.in such a way t.at.t.ey complement.t. produce a specific hermit.an mass mat.ix. We find t.at.for specific four-zero t.xt.res, t.e flavor violat.ng Higgs couplings depend only on t.e free paramet.rs t.n β, γf and t.e fermion masses. We use t.e current.bounds on t.e low energy processes t. derive const.aint. on t.e heavy Higgs boson mass, t.nβand γf t.en, we use t.ese const.aint. t. evaluat. t.e LFV Higgs decays, which reach branching rat.os t.at.could be t.st.d at.t.e LHC.
