摘要:
A collimator includes a plurality of first plate-shaped parts, and a plurality of second plate-shaped parts interlocking with the plurality of first plate-shaped parts. Each of the plurality of first plate-shaped parts and the plurality of second plate-shaped parts arranged with a rectangular spacing therebetween and form a grid-like pattern. Each of the first plate-shaped parts comprises a first slotted plate part having a plurality of first slits formed thereon that is fixed to each of the second plate-shaped parts. A second slotted plate part having a plurality of second slits formed thereon is coupled to a side of the second plate-shaped parts opposite to the first slotted plate part. An adjustment plate part is disposed between the first slotted plate part and the second slotted plate part.
摘要:
A method of determining the presence or the absence of a glaucoma risk by detecting in vitro an allele and/or a genotype of a single nucleotide polymorphism, comparing the allele and/or the genotype detected with at least one of an allele and/or a genotype with a high-risk allele, wherein the presence of a glaucoma risk is determined in a case where the allele detected is the high-risk allele, or the presence of a glaucoma risk is determined in a case where the genotype detected is a homozygote of the genotype comprising the high-risk allele or a heterozygote when the high-risk allele complies with a dominant genetic model, or the presence of a glaucoma risk is determined in a case where the genotype detected is a homozygote of the genotype comprising the high-risk allele when the high-risk allele complies with a recessive genetic model.

摘要:
A method of determining the presence or the absence of a glaucoma risk, including the steps of detecting in vitro an allele and/or a genotype of a single nucleotide polymorphism which is located on a 31st base of a base sequence, in a sample from a subject, wherein the base sequence is at least one base sequence selected from the group consisting of base sequences shown in SEQ ID NOs: 203 to 514 or a complementary sequence thereto (step A), and comparing the allele and/or the genotype detected in the step A with at least one of an allele and/or a genotype, containing a high-risk allele, in the base sequences shown in SEQ ID NOs: 203 to 514 (step B). According to the method of the present invention, the level of an onset risk of glaucoma in a sample donor can be determined by analyzing an allele or a genotype of a single nucleotide polymorphism in the present invention on the sample, so that the sample donor can take a preventive measure of glaucoma, or can receive appropriate treatments, on the basis of this risk.
