OBJECTIVE To determine the difference of visual field defects between acute angle-closure glaucoma (AACG) and chronic angle-closure glaucoma (CACG) and to analyze the difference in the changes of visual field between primary angle-closure glaucoma (PACG) and primary open angle glaucoma (POAG). METHODS This retrospective case series study consisted of 53(More)
OBJECTIVE To observe the expression of heat shock protein 27 (HSP27) in retinal ganglion cells in experimental rat glaucoma model and to study the relationship between HSP27 expression and hypertension using serum autoantibodies. METHODS Forty nine Wistar rats were randomly divided into ocular hypertension group, sham control group and normal control(More)
OBJECTIVE To investigate the prevalence and causes of blindness and moderate and severe visual impairment among adults aged ≥ 50 years in Luxi County of Yunnan Province, China. METHODS It was a population-based cross-section study. Geographically defined cluster sampling was used in randomly selecting 5575 individuals aged ≥ 50 years in Luxi County. The(More)
Visual field is critical to evaluation of glaucoma progression. Various methods of detection of progression were used in clinical practice, but none of them is received as an ideal standard. It is very difficult to choose a method to distinguish progressive glaucomatous visual field loss from test variability. To help analysis visual field progression and(More)
OBJECTIVE The present study was undertaken to examine the expression of pigment epithelium-derived factor (PEDF) in the retina of adult rat following hypobaric hypoxic exposures. METHODS Forty-eight adult Wistar rats were divided into 6 groups randomly (8 rats in each group), of which 5 groups (40 rats) were subjected to hypobaric hypoxia for 2 hours(More)
OBJECTIVE To evaluate the effects of laser in situ keratomileusis (LASIK) on the patients' visual field. METHODS 92 eyes of 46 patients with mild, moderate, and high degrees of myopia were undergone LASIK. Perimetry was performed before and 1 day, 1 month, 3 months, 6 months after LASIK surgery by Humphrey II-750 visual field analysis. The central 30 - 2(More)

Coexisting glaucoma and cataract is a common eye disorder in elderly population. Recent advances in the management of patients with coexisting cataract and glaucoma offer a promising alternative in patients with uncontrolled glaucoma and a cataract and provide an individualized treatment depending upon patient's characteristics and intraocular pressure(More)
PURPOSE The prevalence of primary open-angle glaucoma (POAG) in China has been reported previously, and was lower than that in white and black populations. However, the incidence of POAG in China has not been reported. Therefore, a longitudinal study was conducted to determine the 5-year cumulative incidence and predictors of POAG in China. DESIGN(More)
OBJECTIVE To investigate the opsin expression in form-deprived and defocus myopia in guinea pig and to study the relationship between the opsin expression and the experimental myopia. METHODS Fifty guinea pigs were randomized into form-deprived group, defocus group (n = 20 in each group) and normal group (n = 10). Guinea pigs in form-deprived group wore a(More)
Glaucoma, a type of optic neuropathy, is characterized by the loss of retinal ganglion cells. It remains controversial whether c-Jun N-terminal kinase (JNK) participates in the apoptosis of retinal ganglion cells in glaucoma. This study sought to explore a possible mechanism of action of JNK signaling pathway in glaucoma-induced retinal optic nerve damage.(More)
