Visual attention is a mechanism that enables the visual system to detect potentially important objects in complex environment. Most computational visual attention models are designed with inspirations from mammalian visual systems.However, electrophysiological and behavioral evidences indicate that avian species are animals with high visual capability that can process complex information accurately in real time. Therefore,the visual system of the avian species, especially the nuclei related to the visual attention mechanism, are investigated in this paper. Afterwards, a hierarchical visual attention model is proposed for saliency detection. The optic tectum neuron responses are computed and the self-information is used to compute primary saliency maps in the first hierarchy. The 'winner-takeall' network in the tecto-isthmal projection is simulated and final saliency maps are estimated with the regularized random walks ranking in the second hierarchy. Comparison results verify that the proposed model, which can define the focus of attention accurately, outperforms several state-of-the-art models.This study provides insights into the relationship between the visual attention mechanism and the avian visual pathways. The computational visual attention model may reveal the underlying neural mechanism of the nuclei for biological visual attention. 展开更多

Recent studies on no-reference image quality assessment (NR-IQA) methods usually learn to evaluate the image quality by regressing from human subjective scores of the training samples. This study presented an NR-IQA method based on the basic image visual parameters without using human scored image databases in learning. We demonstrated that these features comprised the most basic characteristics for constructing an image and influencing the visual quality of an image. In this paper, the definitions, computational method, and relationships among these visual metrics were described. We subsequently proposed a no-reference assessment function, which was referred to as a visual parameter measurement index (VPMI), based on the integration of these visual metrics to assess image quality. It is established that the maximum of VPMI corresponds to the best quality of the color image. We verified this method using the popular assessment database—image quality assessment database (LIVE), and the results indicated that the proposed method matched better with the subjective assessment of human vision. Compared with other image quality assessment models, it is highly competitive. VPMI has low computational complexity, which makes it promising to implement in real-time image assessment systems. 展开更多

AIM: To validate the ability of the Heidelberg Edge Perimeter (HEP) in detecting glaucomatous visual field (VF) defects compared to the Octopus Visual Field (OVF) Analyzer and to determine the test-retest repeatability of both modalities. METHODS: This prospective, cross-sectional study was conducted at Wills Eye Hospital, Philadelphia, PA. Glaucoma subjects and unaffected controls underwent VF testing using HEP standard automated perimetry (SAP) III 30-2 Adaptive Staircase Thresholding Algorithm (ASTA) FAST protocol and OVF G-TOP white-on-white strategy. Testing order was randomized. Pearson’s correlation coefficient was calculated for both mean deviation (MD) and pattern standard deviation/square root of loss of variance (PSD/sLV). Receiver operating characteristic (ROC) curves were used to determine the diagnostic abilities of both modalities. Glaucoma subjects returned for repeat testing and intraclass correlation coefficients (ICCs) were calculated to assess test-retest repeatability. RESULTS: Seventy-nine subjects with glaucoma and 36 unaffected controls were enrolled. HEP and OVF were significantly correlated for both MD (r=-0.84;P<0.01) and PSD/sLV (r=0.79;P<0.01). Areas under the ROC curves (AUCs) were also comparable between HEP and OVF for both MD (0.74 and 0.79, respectively;P=0.26) and PSD/sLV (0.74 and 0.82;P=0.08). ICC was high for both HEP (0.96 for MD, 0.95 for PSD/sLV) and OVF (0.82 and 0.88, respectively). Mean test duration (min) was significantly shorter for OVF (2.63) compared to HEP (5.15;P<0.01). CONCLUSION: HEP and OVF show strong correlation for both MD and PSD/sLV, and have similar validity for detecting glaucoma. The test-retest repeatability is high for both HEP and OVF, however the average testing duration of HEP is significantly longer than that of OVF. 展开更多

AIM: To measure and analysis axial length(AL)/corneal radius of curvature(CRC) ratio and other refractive parameters, provide a medical reference range for refractive development evaluation and earlier visual impairment screening of 3 to 4 y kindergarten students.METHODS: Between April and June 2017, a total of 4350 participants aged 3-to 4-year-old(8700 eyes) from 10 cluster random sampling kindergartens in Shanghai, Pudong District were involved. According to the measurement and analysis of the unaided visual acuity(VA), AL, CRC, AL/CRC ratio, astigmatism and other refractive parameters, the data distribution and reference range were obtained.RESULTS: Uncorrected VA of examined children was 0.23±0.08(logMAR, mean±SD) [95% confidence interval(CI) range ≤0.36];AL was 22.10±0.79 mm(95%CI 20.55-23.65);CRC was 7.86±0.26 mm(95%CI, 7.35-8.37);AL/CRC ratio was 2.81±0.12(95%CI, 2.57-3.05). The median of astigmatism was-0.5 D, a total of 56.3% had astigmatism <-0.50 D, 85.3%<-1.00 D, 6.7%>-1.50 D;71% were astigmatism with the rule. Eye-specific analyses were conducted. Statistical difference of VA was in right and left eyes. There were no significant differences between two eyes of AL, CRC, AL/CRC ratio and astigmatism(P>0.05).CONCLUSION: VA and AL/CRC ratio reference could be used to assess refractive development in children and screening uncorrected refractive errors or amblyopia. Astigmatism needs to be considered in the diagnosis. 展开更多

Objective: This project is to analyze and evaluate the efYect of the painless technique in the visual induced abortion. Methods: 300 pregnant women who needed induced abortion and had no contraindication were selected as the research objects. Under the condition of the informed consent of the pregnant women, they were divided into two groups according to the different methods of the induced abortion. 150 cases in the observation group were treated with the painless technique for visual abortion, and 150 cases in the control group were treated with the painless technique for the blind curettage. Relevant surgical indicators and complications were compared between the two groups. Results: The operation time, the vaginal bleeding time, the induced abortion syndrome, the uterine aspiration incompleteness, and the postoperative infection in the observation group were significantly lower than those in the control group. The difference between the two groups was significant (P 0.05), with the statistical significance. The incidence of complications in the observation group (8.33%) was significantly lower than that in the control group (37.50%). The difference between the two groups was significant (P 0.05), with the statistical significance. Conclusion: The visual induced abortion with the painless technique is of great value in the outpatient induced abortion, and it is worth adopting and applying. 展开更多

Cover ratio of cloud is a very important factor which affects the quality of a satellite image, therefore cloud detection from satellite images is a necessary step in assessing the image quality. The study on cloud detection from the visual band of a satellite image is developed. Firstly, we consider the differences between the cloud and ground including high grey level, good continuity of grey level, area of cloud region, and the variance of local fractal dimension (VLFD) of the cloud region. A single cloud region detection method is proposed. Secondly, by introducing a reference satellite image and by comparing the variance in the dimensions corresponding to the reference and the tested images, a method that detects multiple cloud regions and determines whether or not the cloud exists in an image is described. By using several Ikonos images, the performance of the proposed method is demonstrated. 展开更多

Internal carotid artery dissection(ICAD) results from disruption of the intima of the arterial wall, and can lead to intrusion of blood into the arterial wall and form an intramural hematoma. The hematoma can compress the true lumen of the vessel, causing functional stenosis or occlusion. The classic triad signs of ICAD include pain in the ipsilateral neck, head and orbital regions;a(partial) Horner syndrome;and cerebral or retinal ischemia. However, not all ICAD patients present with this classic signs. In some cases, ocular manifestations are the initial(and sometimes the only) findings. We summarize the ocular manifestations associated with ICAD in 3 categories: visual symptoms, oculosympathetic palsy, and ocular motor nerve palsy. 展开更多

Glaucoma is a chronic, progressive optic neuropathy characterized by the loss of peripheral vision first and then central vision. Clinically, normal tension glaucoma is considered a special subtype of glaucoma, in which the patient’s intraocular pressure is within the normal range, but the patient experiences typical glaucomatous changes. However, increasing evidence has challenged the traditional pathophysiological view of normal tension glaucoma, which is based only on intraocular pressure, and breakthroughs in central nervous system imaging may now greatly increase our knowledge about the mechanisms underlying normal tension glaucoma. In this article, we review the latest progress in understanding the pathogenesis of normal tension glaucoma and in developing imaging techniques to detect it, to strengthen the appreciation for the connection between normal tension glaucoma and the brain. 展开更多

AIM: To gain a better understanding of the overall efficacy of valproic acid(VPA) treatment for retinitis pigmentosa(RP). METHODS: Publications in PubMed, EMBASE, Cochrane Library, Web of Science and Clinicaltrials.gov were searched for clinical trials of patients with RP assigned to treatment with VPA. Patients’ pre-and post-treatment visual field(VF) and best-corrected visual acuity(BCVA) scores were extracted and compared to assess changes. RESULTS: A total of 78 reports were retrieved and 6 studies involving 116 patients were included in the Meta-analysis.The combined results showed a significant decrease in logarithm of minimal angle of resolution(logMAR) scores,calculated using baseline and post-treatment BCVA(P<0.00001, mean difference=-0.05, 95%CI:-0.05,-0.04,I2=36%) scores, which means there was considerable improvement in visual acuity. Meanwhile, more BCVA changes were observed in short-term(≤6 mo) treatment studies(P<0.00001, mean difference=-0.05, 95%CI:-0.05,-0.04, I2=38%), studies conducted in Asia(P<0.00001,mean difference=-0.05, 95%CI:-0.05,-0.04, I2=4%), studies with a sample size of 30 or fewer patients(P<0.00001,mean difference=-0.05, 95%CI:-0.05,-0.04, I2=38%) and prospective studies(P<0.00001, mean difference=-0.05,95%CI:-0.05,-0.04, I2=0%). However, VPA’s effect on VF was inconsistent across studies(P=0.75, mean difference=-22.76, 95%CI:-160.56, 115.05, I2=68%). CONCLUSION: This Meta-analysis reveals that most RP patients who were treated with VPA showed improvement in BCVA. However, its effect on VF remains inconsistent.VPA may be a promising treatment for RP. 展开更多

BACKGROUND Diabetic retinopathy(DR)separately has been noted as a major public health problem worldwide as well.Currently,many studies have demonstrated an association between diabetic nephropathy and DR in type 1 diabetes mellitus(T1DM)patients,but this association is less strong in T2DM.The evidence for an association between renal function and DR and visual impairment among T2DM patients is limited,particularly in the Asian population.AIM To assess the association between glomerular filtration rate(GFR)and DR,severe DR,and severe visual impairment among T2DM patients in Thailand.METHODS We conducted a nationwide cross-sectional study based on the DM/HT study of the Medical Research Network of the Consortium of Thai Medical Schools.This study evaluated adult T2DM patients from 831 public hospitals in Thailand in the year 2013.GFR was categorized into≥90,60-89,30-59 and<30 mL/min/1.73 m^2.The association between GFR and DR,severe DR,and severe visual impairment were assessed using multivariate logistic regression.RESULTS A total of 13192 T2DM patients with available GFR were included in the analysis.The mean GFR was 66.9±25.8 mL/min/1.73 m^2.The prevalence of DR,proliferative DR,diabetic macular edema,and severe visual impairment were 12.4%,1.8%,0.2%,and 2.1%,respectively.Patients with GFR of 60-89,30-59 and<30 mL/min/1.73 m^2 were significantly associated with increased DR and severe DR when compared with patients with GFR of≥90 mL/min/1.73 m^2.In addition,increased severe visual impairment was associated with GFR 30-59 and<30 mL/min/1.73 m^2.CONCLUSION Decreased GFR was independently associated with increased DR,severe DR,and severe visual impairment.GFR should be monitored in diabetic patients for DR awareness and prevention. 展开更多
