Increasing numbers of crime cases over the years in Mumbai have caused concerns on the safety of citizens living in Mumbai City. There are some areas which can be called as a crime hotspot and the citizens can be roaming in such areas with no idea about how much danger they are in. To curb this problem there should be a solution feasible and accessible to each person. The proposed system may serve as a crime deterrent to increase security that enables the user to be notified in various ways and may transform their mobile devices into smart personal emergency phones. The proposed system gives valuable information on crime prone areas in a densely populated city. The proposed project can be summarized as a safety app for citizens of Mumbai, or tourists travelling from other states or countries. The project can assist these users by providing Risk alert notification, Nearby police stations, Nearby Hospitals, Emergency panic button and Emergency helpline contact numbers. With the help of these features it makes it easy for the citizens and tourists to be aware of any danger they might be in.
Glaucoma is a primary cause of irreversible blindness worldwide, it kills the vision silently, having a financial burden on society regarding therapy expenses and loss of valuable hours of the day. Objective: To compare the choroidal filling time and grade the status and pattern of optic nerve head (ONH) perfusion by fundus fluorescein angiography (FFA) in glaucoma patients Methods: Patients with various types of glaucoma were enrolled and compared them with healthy volunteers with no history and findings of glaucoma. Perfusion status using FFA was studied and analyzed corresponding visual fields (VF) and optical coherence tomography (OCT) findings Results: There were 70 participants in the study, including 48 glaucoma patients and 22 healthy controls. Choroidal filling time (CFT) was 9-12, 13-17, 15-22, and 20-33 seconds in healthy individuals and patients with ocular hypertension (OH), primary open-angle glaucoma (POAG), and normal-tension glaucoma (NTG), respectively. In OH, inferonasal and inferotemporal hypofluorescence pattern of ONH perfusion was noted, whereas POAG showed an inferonasal, patchy, and undefined pattern of hypofluorescence. In contrast with the healthy volunteers that showed uniform fluorescence, patients with NTG showed inferonasal hypofluorescence. CFT was significantly delayed in NTG patients (p<0.05). We found a strong correlation between findings of FFA, OCT, and corresponding VF defects in glaucoma patients Conclusions: The choroidal filling time is prolonged in patients with various types of glaucoma, especially in cases of normal-tension glaucoma. FFA reveals perfusion defects in the form of areas of hypofluorescence and multiple characteristic optic nerve head perfusion patterns in cases of POAG, NTG, and OH.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
