Purpose: Describe the prevalence of visual impairment/blindness among older adults in rural populations in China. Design: Population-based, cross-sectional study. Participants: We evaluated 45 747 adults ≥50 years of age. Methods: Geographically defined cluster sampling was used in randomly selecting a cross-section of residents from a representative rural county within each of 9 provinces in mainland China. Participants were enumerated through village registers followed by door-to-door household visits. Eligible persons were invited to local examination sites for visual acuity (VA) testing and eye examination. Main Outcome Measures: Presenting and best-corrected distance VA. Results: Of 50 395 enumerated eligible persons, 45 747 (90.8%) were examined and tested for VA. The prevalence of presenting visual impairment <20/63 to ≥20/400 in the better eye was 10.8% and blindness (<20/400) was 2.29%. Across the 9 provinces, presenting visual impairment ranged from 6.89% to 15.8%, and blindness from 1.27% to 5.40%. With best-corrected VA, the prevalence of visual impairment was 5.30%, and 1.93% for blindness. The ranges across the 9 provinces were 3.13% to 9.51% for visual impairment and 0.74% to 4.95% for blindness. Visual impairment and blindness were associated with older age, female gender, lack of education, and geographic area (province) with both presenting and best-corrected VA. Conclusions: Visual impairment and blindness are important public health problems in rural China, with significant regional variations in prevalence. Blindness prevention programs targeting the rural elderly should be expanded, particularly in areas with limited access and affordability of eye care services. Special emphasis should be given to reaching women and those without education. Greater attention should also be given to correction of refractive error.

AIM: To investigate the long-term effect of the nursing care based on differentiation of symptoms and signs on the Vogt-Koyanagi-Harada's syndrome (VKH). METHODS: Ninety-six patients with VKH were randomly divided into an experimental group (48 cases, treated with conventional therapy and nurse combined with nursing care based on differentiation of symptoms and signs) and a control group (48 cases, treated with conventional therapy and nurse). After that, the differences in long-term effect between two groups were compared. RESULTS: There were significant differences in long-term effect between the experimental group (the excellent effect: 40 cases; the inferior excellent effect: 7 cases; the bad effect: 1 cases) and the control group (the excellent effect; 30 cases; the inferior excellent effect: 15 cases; the bad effect: 3 cases). Long-term effect in experimental group was significantly better than that in control group (P < 0.05). CONCLUSION: The nursing care based on differentiation of symptoms and signs possesses important long-term clinical application value for the patients with VKH.

AIM: To study the clinical and image feature of orbital hematoma, and provide evidence for diagnosis and treatment. METHODS: The patient who were treated in our department in last 4 years were collected, the etiology, clinical feature, image were analyzed. RESULTS: A total of 10 cases of hematoma, 1 case had a clear history of trauma, all patients showed exophthalmos, with different degrees of visual acuity decrease, eye movement disorders. Hematoma within the muscle cone in the cone CT showed high density, and the performance of the front showed quasi-circle. B-ultrasound within 4 days appeared as intense echoes of solid lesions, more than 4 days showed hypoechoic areas, individual had echoes interval inside, CDFI had no blood flow signals within the tumor, a routine MRI was consistent with subacute hemorrhage. Bleeding within 7 days of surgery were seen hematoma blood clot. CONCLUSION: Orbital hematoma took onset suddenly, most of which has no inducement, combined with clinical history, symptom, sign, CT, B ultrasound and MRI, we can obtain correct diagnosis. Operation is an efficient way to those who has no obvious improvement with conservative treatment, and obtains good prognosis.

AIM: To investigate the etiology of neovascular glaucoma (NVG) and provide help for clinical prevention and treatment. METHODS: A total of 120 cases 127 eyes diagnosed with NVG were analyzed retrospectively. RESULTS: The cause of NVG was as follows; central retinal vein occlusion was in 47 cases (39.2%), diabetic retinopathy in 31 cases, including 6 cases were binocular, central retinal arteriovenous occlusion in 3 cases, central retinal artery occlusion in 3 cases, carotid artery stenosis in 4 cases, periphlebitis of retina in 4 cases, 1 case was binocular; 3 cases were ocular injury, Coats' disease in 2 cases, chronic uveitis in 2 cases, retinal detachment in 2 cases, acute retinal necrosis in 1 case, choroidal metastasis of lung cancer in 1 case and 17 cases were uncertain. CONCLUSION: As a kind of refractory glaucoma, NVG has complex etiology ,the main cause is retinal ischemia. Central retinal vein occlusion and diabetic retinopathy are the major etiology of NVG. In addition it is necessary to examine the carotid artery stenosis.

AIM: To observe the clinical features and therapeutic efficacy of congenital esotropia and to follow-up the strabismus changes after surgery and the significance of the early treatment. METHODS: This study added up clinical data of 40 cases with congenital esotropia and made a retrospective analysis for their long-term eye position observation results. RESULTS: In congenital esotropia, postoperatively, the rate of achieving alignment within ± 10 Δ at the last follow-up was significantly low and binocular vision in the group of surgery before 4 years old was significantly higher than that of after 4 years old. CONCLUSION: When cases with congenital esotropia obtain operation in sensitive period of vision development, the functional recovery is good.

AIM: To discuss the effectiveness of bulbar conjunctival flap covering in treating amoebic keratitis. METHODS: The clinical manifestations and treatment of 8 eyes with amoebic keratitis were studied retrospectively. RESULTS: Corneal ulcer excision combined with conjunctival flap covering was done on 8 eyes. Corneal infection was controlled in 7 eyes, and 1 case relapsed after operation. CONCLUSION: Partial resection of corneal ulcer combined with conjunctival flap covering can effectively control amoebic keratitis, and shorten the course, which can provide the conditions for optical keratoplasty.

AIM: To investigate the clinical effects on the deep lamellar keratoplasty for herpes simplex keratitis. METHODS: Deep lamellar keratoplasty was performed on 105 cases with herpes simplex viral keratitis. All of these patients were followed-up for 12-36mo, the corneal graft transparency, visual acuity and viral keratitis recurrence were observed. RESULTS: Among 24 patients after stripping the corneal stroma which was close to the Descemet's membrane, Central area of 81 cases were about 6mm×6mm of to Descemet's membrane. One hundred and one cases of planting beds were transparent. Visual acuity were improved in varying degrees, best corrected visual acuity was greater than 0.5 in 67 cases, 0.3-0.5 in 35 cases, less than 0.3 in 3 cases. There was no recurrence of viral keratitis and rejection cases during the observation period. CONCLUSION: Deep lamellar keratoplasty is an effective technique in the treatment of viral keratitis. It is therefore should be an early surgical treatment for frequent episodes of viral keratitis cases.
