Abstract

It is intended to provide a simple normal-tension glaucoma model capable of spontaneously, age-dependently and surly developing conditions similar to symptoms of normal-tension glaucoma which occurs more frequently in elder people, and a method of evaluating therapeutic effect on normal-tension glaucoma whereby a drug useful in treating and diagnosing can be conveniently screened by using the normal-tension glaucoma model. A normal-tension glaucoma model comprising a nonhuman mammal, which is deficient in a transcriptional regulator NF-κBp50 and thus spontaneously develops the normal-tension glaucoma symptom age-relatedly, an organ or a tissue thereof or cells collected from any of the same. A method of evaluating therapeutic effect on normal-tension glaucoma of a test substance which comprises administering or adding the test substance to the above-described nonhuman mammal, an organ or a tissue thereof or cells collected from any of the same, and measuring a morphological defect, cell count, pressure, the expression amount or activity strength of a protein, the expression amount of a nucleic acid and/or the activity strength of an antibody in the organ, tissue and/or cells as indication(s) for the evaluation.
