PURPOSE: To investigate clinical, anatomic, and electrophysiologic response after single intravitreal injection of bevacizumab for macular edema attributable to retinal vein occlusion. DESIGN: Prospective nonrandomized, interventional case series. METHODS: Twenty-one patients with macular edema attributable to vein occlusion received intravitreal injection of bevacizumab 1.25 mg. Nine patients had central retinal vein occlusion (CRVO), and 12 patients had branch retinal vein occlusion (BRVO). Complete ophthalmic examination including optical coherence tomography (OCT) was done at baseline and follow-up visits. Fifteen patients underwent fluorescein angiography at baseline. Selected patients underwent electroretinography (ERG) and visual evoked potential (VEP) at baseline and follow-up. Follow-up was for 12 weeks. RESULTS: At baseline, mean visual acuity was 20/381 (median, 20/400) and showed improvement to mean 20/135 (median, 20/60) after one month, (P = .001). At 12 weeks, mean visual acuity was 20/178 (median, 20/80) (P = .001). The mean central retinal thickness (CRT) was 647.81 microm (median, 609.00 microm) at baseline and decreased to mean 293.43 microm (median, 222.00 microm) at one month (P = .001). At 12 weeks, mean CRT was 320.90 mum (median, 280.00 microm) (P = .001). ERG and VEP showed no worsening of the waveforms. There was no significant difference in the visual outcome between the BRVO and CRVO groups. CONCLUSION: Intravitreal injection of bevacizumab appears to result in significant short-term improvement of visual acuity and macular edema secondary to vein occlusion. The present report confirms the previous studies. No ocular toxicity or adverse effects were observed. However, prospective, randomized, controlled long-term studies are required with an adequate number of patients.  相似文献

AIM: To report on the utilization of eye care services and its associated factors among those with unilateral visual impairment (VI) in a rural South Indian population. METHODS: A population based cross-sectional study was conducted in three districts (Adilabad, Mahbubnagar and West Godavari) in the state of Andhra Pradesh, India. A detailed interview and a comprehensive eye examination were conducted. Those with unilateral VI were asked questions about noticing any change in vision and on utilization of eye care services. The most important reason reported by the participant for not utilizing the services was used for the analysis. Multiple logistic regression models were used to examine the association between noticing a change in vision and socio-demographic variables such as age, gender, education and area of residence, severity and causes of VI. RESULTS: Among the 4456 participants aged ≥16y who were administered the questionnaire, 53.2% were women, and 54.7% had no education. Of the 489 (11%; 95% CI: 10.1-11.9) people with unilateral VI, 399 (81.6%) participants reported noticing a change in their vision over the last five years but only 136 (34.1%) participants had sought eye care consultation. Those who had any education (OR: 1.9; 95% CI: 1.1-3.2), had blindness (OR: 2.7; 95% CI: 1.4-5.2), and cataract (OR: 2.1; 95% CI: 1.0-4.3) as a cause of unilateral VI were more like to seek eye care consultations. The most commonly reported reasons for not seeking eye care services were “do not have money for eye checkup” in 30.7% of the participants followed by “do not have a serious problem” (30.0%). CONCLUSION: A large proportion of rural population though noticed a change in their vision did not seek eye care due to financial and person-related reasons. Eye care service providers need to address these barriers to enhance the uptake of eye care services among those with unilateral VI.  相似文献

The spectrum of Vogt-Koyanagi-Harada disease in South India   总被引:1,自引:0,他引:1  
Purpose To report the clinical spectrum of Vogt-Koyanagi-Harada (VKH) disease in a tertiary care center in South India. Methods Medical records of patients diagnosed with VKH disease who presented between January 1995 and December 2003, with a minimum follow-up of one year were reviewed. Results Of the 45 patients, 38 (84.44%) were female. The median age was 37 years (SD ± 14.23) and median duration of symptoms was 30 days (range 1 day to 1 year). 75.5% (34/45) presented with bilateral anterior uveitis. Posterior segment presentation included disc edema (31/45), bilateral serous retinal detachments (26/45), vitritis (17/45) and sunset glow (8/45). Extra ocular manifestations were seen in only 4/45 (tinnitus: 2, meningismus: 1, poliosis: 1). 97.7% (44/45) received oral Prednisolone (1 mg/kg body weight) for a median duration of 14 months. 69% (31/45) received additional three pulses of intravenous methylprednisolone and 22% (10/45) received a single infusion of intravenous Cyclophosphamide. One patient received intravitreal triamcinolone injection 53.33% (24/45) were treated with additional immunosupressants. At the first visit, best corrected visual acuity (BCVA) was ≥20/40 in 23 eyes (25.55%) and ≤20/400 in 37 eyes (41.11%). At one year, 61 eyes (67.77%) achieved BCVA of ≥20/40 while 12 eyes (13.33%) had BCVA ≤20/400. Complicated cataract, glaucoma and macular scar were the major complications encountered. Conclusions Majority of patients with ocular VKH presented with anterior uveitis and serous retinal detachments and disc edema. Extra-ocular signs are rare in our patients. Visual prognosis is good with treatment with adequate long-term corticosteroids and immunosuppressive agents.  相似文献

Retinopathy in persons without diabetes: the Los Angeles Latino Eye Study   总被引:1,自引:0,他引:1  
PURPOSE: To assess the prevalence of retinopathy and its relationship to sociodemographic and clinical characteristics in a population-based cohort of adult Latinos without diabetes mellitus. METHODS: This was a population-based, cross-sectional study comprising 6357 Latinos, 40 years of age and older, from six census tracts in La Puente, Los Angeles, California. An interviewer-administered questionnaire assessed sociodemographic factors and medical history. Color fundus photographs were taken and graded in a masked manner according to a modified Airlie House Classification Grading System. Participants underwent a physical examination that included height, weight, blood pressure, random serum glucose, and glycosylated hemoglobin measurements. Univariate and multivariate logistic regression analyses were used to assess associations between sociodemographic and clinical characteristics and retinopathy in persons without diabetes. RESULTS: The prevalence of retinopathy among individuals without diabetes in the Los Angeles Latino Eye Study (LALES) population was 6.6% (95% confidence interval 5.9%-7.4%). Stepwise logistic regression indicated that stage II hypertension (World Health Organization 2003 Guidelines), male gender, current smoking status, and obesity (body mass index >or= 30 kg/m(2)) were associated with retinopathy (odds ratio = 4.3, 1.6, 1.4, and 1.3, respectively). No statistically significant associations with retinopathy were present for Native American ancestry; country of origin; health insurance status; history of cardiovascular disease; or history of aspirin, oral contraceptive, or hormone replacement therapy. CONCLUSIONS: The data suggest that the prevalence of retinopathy in nondiabetic individuals among Latinos of primarily Mexican ancestry is significant. Independent risk indicators for retinopathy in the study population are hypertension, male gender, current smoking status, and obesity.  相似文献

Three‐dimensional analysis of wrist motion is a growing focus in orthopedic research, however, our understanding of its validity (accuracy and reliability) remains limited. Nine human cadavers were tested to estimate wrist joint axes alignment in a postural static pose. The objective was to investigate a rater's ability to reliably align three skin‐ tracked wrist joint coordinate system (WJCS) definitions across baseline and reconstructive wrist states (intact, mid‐carpal arthrodesis, and proximal‐row carpectomy). Two WJCSs (legacy, anatomic) were based on palpated bony landmarks and the third (functional) was based on both landmarks and passive flexion‐extension motion. A coordinate frame based on the anatomic definition was tracked with bone pins and served as a reference. Each WJCS was tested in each wrist state and in three forearm position (45° pronation, neutral, 45° supination). The angular offset about each axis of the WJCS frames were calculated with respect to the reference in flexion‐extension, radial‐ulnar deviation, and pronation‐supination for every iteration. Reliability and root mean square deviation values were analyzed across wrist states. Our data suggest that no WJCS is uniformly more reliable than another. The functional WJCS definition was most consistent across intact and post‐operative states for pronation‐supination offset, but this was dependent on rater interpretation. It still however offers the practical benefit of requiring fewer landmarks. © 2015 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 33:1341–1347, 2015.  相似文献
