An analysis of 194 high-pressure glaucoma patients, 217 normal-pressure
glaucoma patients, and 218 normal controls, showed correlations between
the promoter polymorphism of TNF-a gene and optineurin gene polymorphism
in prevalence of glaucoma and degree of visual field loss.
lthough trabeculectomy with adjunctive use of mitomycine C for normal
pressure glaucoma may result in a statistically significant reduction
of IOP over 4 years, only 40 % of patients obtained 30% reduction from
the baseline.
In a Japanese population based survey, 39 of 3021 subjects (1.3%,
CI:0.9-1.7%) were found to have visual disability or blindness on the
basis of WHO standards. Of these, only 5 were due to glaucoma.
Parameters of Heidelberg Retina Tomography were significantly different
among various types of glaucomatous optic nerve heads (except for the
rim area).
During measurements of diurnal variation of ocular perfusion pressure
in normal-pressure glaucoma patients, ocular perfu
sion pressures were significantly lower at 21:00 and at 24:00 than those
measured at other times, although such a difference was not observed
in patients with high-pressure glaucoma.
The results of Humphrey Matrix visual field, central 10-2 showed
a good correlation with those by Humphrey visual field 10-2, particularly
in the nasal inferior region.
Histological examination of a specimen of the trabecular meshwork
obtained from a patient with glaucoma secondary to vitreous injection
of triamcinolone showed no specific abnormalities resembling steroid
glaucoma.
Candesartan (an angiotensin II receptor inhibitor) reduced intraocular
pressures of normal volunteers significantly for six hours without showing
any significant cardiovascular side effects.
In diurnal variation of the intraocular pressures of ddY mice, a
double hump pattern was observed in those under conditions of darkness
and brightness each for 12 hours.
In normal-pressure glaucoma patients, diurnal variations of the
nerve fiber layer thickness evaluated by GDxVCC were observed, particularly
in the region of nerve fiber layer defects.
