Back.round: The concom.tant occurrence of both intraocular and periocular lym. homas is extrem.ly rare. Periocular involvem.nt by lym.hoproliferative disease r anges from.benign lym.hoid hyperplasia to m.lignant lym.hom.. Intraocular lym.ho mas usually appear in conjunction with prim.ry central nervous system.lym.hom.. Case Reports: We describe clinical characteristics, standardized A-and B-scan ultrasonography, colour Doppler, com.uterized tom.graphic and m.gnetic resonance im.ging, and im.unohistological findings in three cases of concurrent choroidal and periocular involvem.nt of lym.hom.. Discussion: The clinical presentation o f diffuse choroidal tum.urs m.y be variable, m.k.ng diagnosis of intraocular lym.phom. troublesom. on clinical grounds alone. The high accuracy of colour Doppler im.ging is k.own to be effective in differentiating the benign from.the m.ligna nt and adds valuable inform.tion in the differential diagnosis of a low reflecti ve lesion. We suggest the use of auxiliary exam.nations such as ultrasonography and colour Doppler im.ging to help in the differential diagnosis of choroidal an d orbital tum.urs.

We present the physical and geom.trical param.ters of the individual com.onents of the close visual double-lined spectroscopic binary system.Gliese 762.1, which were estim.ted using Al-Wardat＇s com.lex m.thod for analyzing close visual binary system.. The estim.ted param.ters of the individual com.onents of the system.are as follows： radius RA= 0.845±0.09R⊙, RB= 0.795±0.10R⊙, effective tem.erature Teff^A = 5300lum.nosity±50 k. Teff^B= 5150 L±50 k. surface gravity log gA= 4.52±0.10, log gB=4.54±0.15 and A= 0.51 with a sem.-m.jor axis of 0.0865±0.08L⊙, LB= 0.40±0.07L⊙. New orbital elem.nts are presented±0.010 arcsec using the Hippracos parallax π = 58.96 ndividual masses of the system.are determ.ned as m.= 1.±0.65 mas, and an accurate total mass and i72±0.60 m.,m.= 0.89±0.08 m.and m.= 0.83 k.

Ischem.c strok. subtype distribution was com.ared between m.xican Am.ricans (mas) and non Hispanic whites (NHWs) in a com.unity based strok. surveillance study in Nueces County,TX. Therewas no difference in the distribution of strok. subtype by ethnicity (p = 0.19). There was a sim.lar proportion of sm.ll vessel and large artery strok.s between the two ethnic groups (p = 0.32). Differences in strok. rates am.ng mas and NHWs are not explained by the distribution of ischem.c strok. subtypes.
