1. Eyes are precious and need lifelong care to stay healthy.
2. Symptoms like vision loss, redness, pain, or discharge require immediate eye care.
3. General eye care includes exercises, drinking water, avoiding rubbing, good posture while reading, taking breaks from screens, and wearing sunglasses in sunlight.
4. Self-medication can be harmful - any eye problems require consulting an eye specialist.
The document discusses various routes of drug administration according to Ayurveda. It begins by defining route of administration as the path by which a drug comes into contact with the body. It then describes the 9 main routes according to Ayurvedic texts - oral, nasal, ocular, auricular, rectal, genital, dermal, and umbilical. It provides details on various dosage forms, advantages and disadvantages, and factors affecting drug absorption for different routes. The document emphasizes the importance of selecting the appropriate administration route based on the disease condition and properties of the drug.
1) NETRA is an interactive display that estimates refractive errors and focal range by taking the inverse approach of the Shack-Hartmann wavefront sensor. It uses high-resolution displays and user interaction rather than lasers and sensors.
2) The user interacts with patterns on the display to measure their farthest and nearest focal points, allowing NETRA to determine refractive errors like myopia, hyperopia, and astigmatism, as well as the overall focal range.
3) NETRA has applications in low-cost, portable eye exams that could improve eye care access in developing countries. Over 600 million people lack corrective glasses due to limited resources.
THE NEUROLOGICAL SYSTEM -
The neurological system controls body functions and is
inter-related to other body systems i.e. a patient with diabetes
may suffer a stroke

The document describes the Amsler grid chart, which was developed in 1920 by Dr. Marc Amsler to test for central vision disorders. It consists of a grid pattern with white lines on a black background that is used to evaluate the macula. Patients are asked a series of questions while viewing the chart to check for blurriness, distortions, or missing areas that could indicate conditions like macular degeneration or retinal detachment. The document outlines the purposes and procedures for several variations of the Amsler grid and provides instructions for patients to perform self-examinations at home in order to monitor eye conditions.
This document discusses various aspects of the eye in Ayurveda, including its anatomy, physiology, diseases, treatments, importance in diagnosis and various professions, social and preventative aspects, and depictions in literature and mythology. It describes the eye's structures and functions according to Ayurvedic texts, systemic diseases that present in the eye, examination techniques, therapeutic approaches, role in various fields, preventative measures for eye health, and depictions in religious and cultural contexts. The eye is considered the most important sense organ due to its role in 80% of knowledge acquisition, use in diagnosis and professions, and influence over other senses.
This document provides information about Brahmi Ghrita, including its references in Ayurvedic texts, ingredients, indications for use, dosage, and research that has been conducted on it. Brahmi Ghrita is an Ayurvedic ghrita preparation used for treating mental health conditions. It contains Brahmi as the main ingredient along with other herbs like Vacha and is described in classical texts as useful for disorders like mania, epilepsy, and memory problems. Recent studies have found it to have neuroprotective, antioxidant, and memory-enhancing effects.
The document discusses various tests used to evaluate color vision and the central visual field, including the Amsler grid and color vision charts. The Amsler grid is used to screen for macular diseases by having the patient view a grid and report any distortions, gaps, or unusual areas. Color vision tests include pseudoisochromatic plates like Ishihara plates to screen for red-green deficiencies, as well as more advanced tests like the Farnsworth-Munsell 100 Hue test to grade the severity of defects. Spectral tests like the Nagel anomaloscope are also described, which use light mixtures to accurately diagnose color vision abnormalities.

It discusses the concept, areas of application, classification based on mode of action and intensity, parts of plants used, properties of drugs, specific drugs used, seasonal application, procedure including preparation, administration, expected effects, and post-procedure care like samsarjana krama. Virechana is described as useful for eliminating toxins, preventing and curing diseases, and rejuvenating the body. Precautions and contraindications are also outlined.
This document provides an overview of optical coherence tomography (OCT), including its history, principles, types, interpretation, clinical applications, limitations, and recent developments. OCT is a non-invasive imaging technique that uses infrared light to generate high-resolution cross-sectional images of the retina and anterior segment. Newer spectral domain OCT systems provide faster scanning speeds and higher resolution compared to earlier time domain OCT systems. OCT is useful for diagnosing and monitoring retinal diseases like glaucoma as well as anterior segment conditions. Interpretation of OCT images involves identifying layers and structures that appear as various colors based on reflectivity. Recent advances include enhanced depth imaging to view deeper choroidal structures and software to quantify retinal thickness and nerve fiber layer measurements.
This document discusses "Pinda Sweda", an Ayurvedic technique involving the application of herbal boluses or poultices to induce localized sweating. It explores two common types - Patra Pinda Sweda using leaf poultices and Shashtika Shali Pinda Sweda using rice poultices. The document summarizes the physiological effects of Pinda Sweda like increased local blood flow and absorption of herbs through the skin. It also discusses the use of Pinda Sweda in diseases like osteoarthritis, cerebral palsy, and other neuromuscular disorders by regulating vata dosha and removing toxins through the skin. In conclusion, the author calls for further research on the science
Sclera is the opaque outer fibrous tunic of the eyeball. Diseases of the sclera include episcleritis, which involves inflammation of the outer episcleral layer, and scleritis, which is a deeper inflammation of the sclera proper. Scleritis can be non-necrotizing or necrotizing, and is often associated with autoimmune disorders. Other scleral conditions include blue sclera seen in certain genetic disorders, and staphylomas which are localized bulgings of a weakened sclera lined by inner ocular layers.
The document describes the anatomy, histology, blood supply, lymphatic drainage and nerve supply of the conjunctiva. It discusses various types of conjunctivitis including infective, allergic, irritative, traumatic and those associated with skin and mucosal diseases. Specific types described include acute catarrhal, acute purulent, serous, chronic simple, angular and membranous conjunctivitis.
1. The eye lid has 5 layers - skin, muscle layer, submuscular space, fibrous layer, and palpebral conjunctiva.
2. The muscle layer contains the orbicularis oculi and levator palpebrae superioris muscles.
3. The fibrous layer contains the orbital septum and tarsal plate. The tarsal plate contains meibomian glands.
- Visual field examination tests the peripheral sensitivity of the retina and visual pathways. It is important for assessing topographic sensitivity and detecting visual field defects.
- Automated perimetry provides standardized, quantitative tests to measure threshold sensitivity across the visual field. It allows for reliable long-term monitoring to detect glaucomatous progression.
- Interpretation of visual field tests involves analyzing parameters like total deviation plots, pattern deviation plots, and global indices to identify patterns indicative of glaucoma according to established criteria. Clinical correlation with optic nerve examination is also important.

The Web has changed. UI has changed. User expectations have changed. It is time to relook long believed UI development philosophies and principles. Starting from laying out the screen to porting it across platforms UI development has completely changed in the context of RIA technologies like Flex. This session looks at some of the most important factors UI developers have to consider when developing RIA UIs.
I have used images, content, examples liberally from the open web. Thanks to all for those.
The document discusses prototyping and provides three key points about prototyping:
1) Prototyping allows companies and designers to create an initial version of a product or interface in order to learn from it, change it based on feedback, and refine it before full development.
2) There are various tools that can be used for prototyping, ranging from relatively low-fidelity tools like Balsamiq Mockups to more advanced tools like Axure RP.
3) It is important for prototyping to be done quickly without over-engineering, to avoid feature creep and design bias, and not to prematurely take on the responsibilities of front-end development.
