• Background: At this time little information is available about the relationship between glaucomatous visual field defects and impaired blood flow in the optic nerve head. The purpose of this study was to examine blood flow of the juxtapapillary retina and the rim area of the optic nerve head in primary open-angle glaucoma with a borderline visual defect. • Methods: Juxtapapillary retinal and neuroretinal rim area blood flow was measured by scanning laser Doppler flowmetry (SLDF). The visual field was evaluated by static perimetry (Octopus-G1). The optic nerve head was assessed on 15° color stereo photographs. We examined 116 eyes of 91 patients with POAG with controlled IOP and 66 eyes of 44 healthy individuals. The POAG group was divided into eyes with a mean defect lower than 2 dB (POAG group I) and in eyes with a mean defect equal to or greater than 2 dB (POAG group II). The mean age of POAG group I and POAG group II was 55±11 years and 57±10 years, respectively. The mean age of the control group was 45±15 years. The eyes of POAG group I had an average C/D ratio of 0.71±0.18 with an average mean defect of the visual field of 0.97±0.68 dB; the eyes of POAG group II had an average C/D ratio of 0.80±0.17 with an average mean defect of the visual field of 8.2±6.0 dB. The intraocular pressure on the day of measurement in POAG group I was 18.2±3.7 mmHg, in POAG group II 17.6±4.0 mmHg, and in the control group 15.1±2.5 mmHg. For statistical analysis, age-matched groups of 32 normal eyes of 32 subjects (mean age 52±10 years) were compared to 18 glaucomatous eyes of 18 patients (POAG group I, mean age 55±11 years) and 59 glaucomatous eyes of 59 patients (POAG group II, mean age 55±10 years). • Results: In the eyes of POAG group I and POAG group II, both juxtapapillary retinal blood flow and neuroretinal rim area blood flow were significantly decreased compared to an age-matched control group: neuroretinal rim area “flow” POAG group I −65%, POAG group II −66%; juxtapapillary retina “flow” POAG group I −52%, POAG group II −44%. All eyes of the POAG group I (MD<2 dB) and 56 of 61 eyes of the POAG group II (MD>=2 dB) showed a retinal perfusion lower than the 90% percentile of normal blood flow. We found no correlation between reduction of juxtapapillary or papillary blood flow and mean defect in POAG eyes. • Conclusion: Glaucomatous eyes with no defects or borderline visual field defects as well as glaucomatous eyes in an advanced disease stage show significantly decreased optic nerve head and juxtapapillary retinal capillary blood flow.

BACKGROUND: Analysis of clinical importance of the size of filling defects in fluorescein angiograms in primary open-angle glaucoma (POAG), normal-tension glaucoma (NTG), ocular hypertension and subjects with physiological excavations in comparison to visual field loss, optic nerve head morphology and hemodynamics. PATIENTS AND METHODS: 75 patients (POAG, NTG, ocular hypertension) and 10 healthy subjects with physiological excavations were included in this study. In digitized video fluorescein angiograms (Scanning Laser Ophthalmoscope) the size of absolute filling defects of the optic disc was quantified in the early venous phase and expressed by percentage of the optic disc. Visual fields were obtained by conventional static perimetry (Humphrey 24-2) and graded in stages of glaucoma visual field defects (Aulhorn I-V). Optic disc excavations were evaluated as cup-to-disc-area-ratios. RESULTS: The filling defects correlated with the visual-field loss stages of Aulhorn and the visual field indices MD (mean deviation), PSD (pattern standard deviation) and CPSD (corrected pattern standard deviation). There was no correlation with the index SF (short-term fluctuation) and with systemic hemodynamics (blood pressure, perfusion pressure) or the IOP. Absolute filling defects correlated with the cup-to-disc-area-ratio in NTG. The absolute filling defects were larger in patients with glaucoma (POAG, NTG) in comparison to patients without glaucomatous visual field loss (ocular hypertension, glaucoma-like discs). No difference of filling defects was found in the glaucoma group (POAG, NTG). Patients with NTG had larger excavations and lower systolic blood pressures than patients with POAG. CONCLUSION: The size of fluorescein filling defects may be useful as a parameter for the evaluation of an ischemic lesion of the optic nerve head. Absolute filling defects may differentiate POAG from ocular hypertension and NTG from glaucoma-like discs without field defects. The results support the hypothesis that in POAG and NTG disturbances of the circulation result in similar filling defects of the optic disc and visual field loss.  相似文献

PURPOSE: To determine the retrobulbar hemodynamics in glaucoma patients with different degrees of optic nerve damage. METHODS: Color Doppler imaging was performed in 52 patients with controlled primary open angle glaucoma (POAG) and in 25 control subjects. Glaucomatous eyes were divided into early and late groups based on the perimetry findings. Peak systolic velocity (PSV), end diastolic velocity (EDV), and resistive index of the central retinal artery (CRA) and posterior ciliary arteries (PCA) were evaluated. RESULTS: Early glaucoma showed significantly decreased PSV in nasal PCA when compared with the normal. Late glaucoma showed significantly decreased PSV and EDV in the CRA and nasal PCA, and significantly decreased PSV in temporal PCA as compared with the control and early glaucoma. The resistive index of the CRA also increased significantly in late glaucoma. CONCLUSION: Eyes with advanced glaucomatous optic neuropathy were associated with more marked alterations in retrobulbar circulation than eyes with less nerve damage.  相似文献

PURPOSE: To study the relationship between optic nerve head blood flow velocity and visual field loss in patients with primary open-angle glaucoma (POAG) and normal tension glaucoma (NTG). METHODS: This study included 44 eyes of 44 patients with POAG and 44 eyes of 44 patients with NTG. To evaluate optic nerve head blood flow velocity, the square blur rate (SBR) was measured by means of laser speckle flowgraphy. The correlation between SBR and Humphrey visual field indices was evaluated with linear regression analysis. RESULTS: In the NTG group, the average SBR at the superior and inferior temporal neuroretinal rim was positively correlated with mean deviation (MD) (r = 0.349, p = 0.020). The SBR at the superior or inferior temporal neuroretinal rim was positively correlated with the sum of the total deviations in the corresponding hemifields (r = 0.299, p = 0.049; r = 0.354, p = 0.019, respectively). The correlations between SBR and MD did not differ statistically between the NTG and POAG groups; however, no significant correlation between SBR and visual field indices was observed in the POAG group. CONCLUSION: These results suggested that the change in the circulation of the optic nerve head may be related to visual field damage in the NTG group but may be less involved in visual field damage in the POAG group.  相似文献

Both primary open-angle and normal-tension glaucoma belong to an identical spectrum of diseases. Clinical presentations of primary open-angle or high-tension glaucoma (POAG) and normal-tension glaucoma (NTG) were studied in an attempt to determine prognostic, clinical factors and define the appropriate management. Clinical data obtained from 826 primary open-angle and normal-tension glaucoma patients were analyzed. In addition, the results of laboratory studies, including the immunological assay of heat shock protein (hsp) and gene analyses which were undertaken to identify risk factors at the molecular level, are discussed. 1. The identified prognostic factors were disk hemorrhage, peripapillary chorioretinal atrophy (PPA), maximum intraocular pressure (IOP), the recovery rate of skin temperature after exposure to cold, family history of glaucoma, systemic systolic channel blood pressure, and oral administration of Ca(2+)-channel antagonists. 2. Disk hemorrhage was observed in 30.5% of NTG patients and 15.4% of POAG patients. Cumulative probability of hemorrhagic events was 16.9% in POAG and 38.4% in NTG patients at the end of a 14.8-year follow-up. 3. The hazard ratio of disk hemorrhage decreased with the increase of IOP(26%/5 mmHg) and was 1.46 times higher in females than in males. Disk hemorrhage was closely associated with PPA: PPA becomes greater in association with the progression of glaucomatous optic neuropathy in both POAG and NTG. No such correlation was noted in primary angle-closure glaucoma. 4. Color Doppler imaging analyses and the hourly determination of ocular perfusion pressure (OPP) indicated a difference in retrobulbar hemodynamics between OPP-mean deviation concordant and OPP-mean deviation discordant patients: a circulatory disturbance causally unrelated to OPP seems to be involved in the OPP-mean deviation discordant patients. 5. The oral administration of Ca(2+)-channel antagonists was shown to favorably influence retrobulbar hemodynamics in NTG patients. 6. Serum antigen titer to hsps(hsp 27, alpha B crystallin, human & bacterial hsp 60) was higher in both POAG and NTG patients than in normal subjects. None of the hsp-antigens was correlated to any morphometric parameters of the optic disk or any global indices of the visual field. 7. Myocilin mutation was noted in only 0.5% of POAG patients and 2.37% of NTG patients. The very low rate of occurrence precludes the value of mutation of the gene as a prognostic factor in open-angle glaucoma(OAG). 8. IOP reduction achieved by mitomycin-C trabeculectomy is effective in maintaining visual function in OAG eyes. 9. Brovincamine fumarate is effective in inhibiting the progression of glaucomatous field loss in NTG.  相似文献
