Abstract: Objective To observe the effect of vascular factors on normal tension glaucoma(NTG). Methods The NTG group of 40 eyes,and the age and sex matched normal control group of 40 eyes were enrolled in this study. Color Doppler flow image (CDFI) was used to analyze the peak systolic velocity(PSV), the end diastolic velocity(EDV) and the resistance index(RI) of the carotid artery(CA), the internal carotid artery(ICA), the ophthalmic artery(OA), the central retinal artery(CRA) and the shortposterior ciliary artery(SPCA). Results The PSV of ICA,OA,CRA and SPCA in the NTG group was decreased (P<0.01, P<0.05) and RI was significantly increased (P<0.01).The EDV of OA and CRA in the NTG group compared with the normal control group was decreased (P<0.01, P<0.05), while the EDV of ICA and SPCA in the NTG group compared with the normal control group showed no significant difference (P>0.05), and the parameters of CA in the NTG group compared with the normal control group showed no significant difference (P>0.05). Conclusion The increasing RI of ICA, OA, CRA and PCA should be used as important indicators in the early diagnosis and judgment prognosis of NTG, and should also be referred to if the EDV numerical value of OA and CRA is decreased, to provide favorable information for judgment prognosis and treatment project of NTG patients.

[13] ObjectiveTo discuss the causes and appropriate treatment for iris neovascularization following the analysis of cases( eyes). MethodsIt was a retrospective case series study involving patients( eyes)with iris neovascularization diagnosed between September and July . All the patients underwent ophthalmic examination, and all the examination findings and treatments were recorded. The causes, correlative factors, and treatment outcomes of iris neovascularization were analyzed. ResultsOf the patients, ( eyes, .%)had retinal ischemic signs, including vitreous hemorrhage and retinal vascularization on fundus fluorescein angiography, ( eyes, .%)did not have retinal ischemic signs. After months of treatment, retinal vascularization resolved in all the cases, and iris neovascularization resolved completely in patients( eyes, .%), iris neovascularization was still found in patients( eyes, .%). ConclusionsAnterior segment ischemia may also lead to iris vascularization, although retinal ischemia was the main cause. Additionally, iris neovascularization may not always resolve with treatment for retinal ischemia. Finally, anti-VEGF drug injection was an effective treatment for iris neovascularization..

[14] ObjectiveTo discuss the early diagnosis and multidisciplinary diagnosis and treatment of neovascular glaucoma in ocular ischemic syndrome. MethodsThe medical records of a 54-year-old male patient with cerebral infarction who presented with right-eye vision loss that had persisted for a week were reviewed. After slit-lamp examination and fluorescence angiography, he was diagnosed with ocular ischemic syndrome(OIS)complicated by neovascular glaucoma in the right eye and treated with intravitreal injection of anti-VEGF drugs and panretinal photocoagulation. ResultsAfter three months of treatment, the right-eye iris neovascularization subsided, and the intraocular pressure was controlled within normal limits. ConclusionOcular ischemia is often missed or misdiagnosed by ophthalmologists, neurologists, cardiologists, and vascular surgeons due to its insidious onset and complex clinical manifestations. Therefore, the establishment of multidisciplinary diagnosis and treatment can improve the prognosis of OIS patients..
