Cataracts are the leading cause of vision loss worldwide and occur when the lens of the eye becomes cloudy. There are three main types of cataracts: subcapsular, nuclear, and cortical, each affecting a different part of the lens. Cataracts are most commonly caused by aging but can also be due to diabetes, smoking, sun exposure, eye trauma, or radiation exposure. Symptoms include blurred vision, sensitivity to light, and frequent changes in prescription glasses or contacts. Cataract surgery removes the cloudy natural lens and replaces it with an artificial lens to improve vision.

Cataract.pdf
A cataract is a clouding of the lens in the eye that impairs vision. It begins with proteins in the lens clumping together which disrupts the passage of light. Over time, cataracts can cause blindness if left untreated. The main types of cataract are age-related cataracts and traumatic cataracts caused by eye injuries. Treatment involves surgically removing the cloudy lens and replacing it with an artificial lens through procedures like phacoemulsification. Potential complications include inflammation, increased eye pressure, and posterior capsule opacification.

This document discusses three common eye disorders: cataracts, glaucoma, and conjunctivitis. It defines each disorder and describes their causes, risk factors, signs and symptoms, diagnostic tests, and treatment options. Cataracts involve cloudiness of the lens, glaucoma damages the optic nerve leading to vision loss, and conjunctivitis is an inflammation of the conjunctiva commonly known as pink eye. Surgical intervention may be required for cataracts and glaucoma to prevent further vision impairment.

This document discusses cataracts, including their definition, risk factors, types, clinical manifestations, diagnostic tests, management, and complications. Cataracts are an opacity of the lens that can impair vision. The most common type is age-related senile cataracts, which usually begin around age 50. Risk factors include aging, UV exposure, diabetes, corticosteroid use, and trauma. Diagnosis involves visual acuity and slit lamp tests. Treatment is surgical removal of the clouded lens and replacement with an intraocular lens. Complications can include infection, bleeding, and posterior capsule opacification.
Glaucoma and cataract include treatment
Glaucoma is a group of eye diseases characterized by increased intraocular pressure, optic nerve damage, and visual field loss. It is a leading cause of blindness worldwide. Cataracts are cloudy lenses that reduce vision and are most often age-related. They occur when the lens becomes less transparent over time. Risk factors for cataracts include diabetes, corticosteroid use, and glaucoma. Both conditions are generally treated surgically by removing the opaque lens or reducing eye pressure, but vision lost from glaucoma cannot be recovered. A combined study found diabetes significantly increases cataract risk while glaucoma is also an independent risk factor, potentially causing 5% of all cataracts.
Glaucoma.pptx
This document discusses glaucoma, which is characterized by optic nerve damage and elevated intraocular pressure caused by congestion of fluid in the eye. It can cause vision loss or blindness but is usually asymptomatic until late in the disease. Risk factors include age, family history, diabetes, and corticosteroid use. Treatment aims to prevent further optic nerve damage through medication, laser treatment, or surgery. The document also discusses cataracts, which are lens opacities that are the leading cause of blindness. Cataracts develop due to aging, trauma, radiation exposure, or systemic conditions. Early cataracts are treated with glasses but later cataracts require surgical removal and lens replacement.

Summary
Cataract
Cataract is a cloudiness of the lens of the eye that can develop at any age and is the leading cause of blindness worldwide. It occurs when the lens becomes progressively opaque, blocking light from passing through the eye to the retina. Cataract surgery involves removing the cloudy lens and replacing it with an artificial intraocular lens to restore vision. Post-operative care includes administering antibiotic and steroid eye drops to prevent infection and reduce inflammation.

ARTHRITIS.pptx
Rheumatoid arthritis (RA) is an autoimmune disorder that causes inflammation in the joints, while gouty arthritis is caused by a buildup of uric acid crystals in the joints. RA typically causes long-lasting morning stiffness and a lack of range of motion in symmetrically affected joints like both hands, whereas gout causes sudden hot, red, swollen joints and asymmetric involvement. While the symptoms of both can be painful, gout tends to be more treatable and have better prognosis. Maintaining a healthy diet and weight can help reduce risks for both conditions.

Alzheimer's disease is a progressive brain disorder that destroys memory and thinking skills. While the causes are not fully known, risk factors include genetics such as variations in the APOE-e4, APP, PS-1, and PS-2 genes which have been linked to an increased likelihood of developing the disease. Common signs and symptoms include memory loss, problems with thinking and reasoning, and behavioral changes.
6_histo_bone.ppt
Bones are composed of organic and inorganic materials and serve several functions including support, protection, movement, storage, and blood cell production. Bones are classified based on their shape and internal structure. Long bones have a diaphysis and epiphyses, while flat bones are thin and curved. Bone tissue is either woven or lamellar, and bones contain cancellous or compact bone. Bones develop through intramembranous or endochondral ossification and continue growing after birth through growth at the epiphyseal plate and periosteal apposition. Bone is remodeled throughout life by basic multicellular units and fractures heal through hematoma formation, callus formation, callus ossification, and remodeling
12_heart.ppt
The document discusses the anatomy and functions of the heart. It describes the heart's location in the chest cavity and its shape. The heart has four chambers - two upper atria and two lower ventricles. Blood flows from the veins into the right atrium, then into the right ventricle and to the lungs before returning to the left atrium and ventricle and being pumped back into the arteries. Heart valves ensure one-way blood flow. The cardiac cycle involves coordinated contractions of the atria and ventricles.
Blood_vessels.ppt
The peripheral circulation carries blood, exchanges nutrients and gases with tissues, and helps regulate blood pressure. Blood vessels consist of arteries, which carry blood away from the heart, and veins, which carry blood toward the heart. Arteries branch into smaller arterioles and capillaries, where exchange occurs, and capillaries branch into venules and veins to return blood to the heart. The circulatory system transports blood throughout the body via this branching network of vessels.
11_Blood.ppt
Blood functions to transport gases, nutrients, waste products, regulatory molecules, and protects the body. It is composed of plasma and formed elements including red blood cells, white blood cells, and platelets. Red blood cells contain hemoglobin and transport oxygen and carbon dioxide. White blood cells protect against pathogens and remove dead cells. Platelets help form blood clots to prevent blood loss from injuries. Blood typing involves antigens on red blood cells and antibodies in plasma to avoid transfusion reactions.
8_ANS.ppt
The autonomic nervous system is divided into the sympathetic and parasympathetic divisions. The sympathetic division originates in the spinal cord and targets organs through the sympathetic chain ganglia. The parasympathetic division originates in the brainstem and sacral spinal cord and targets organs through terminal ganglia. Both divisions use acetylcholine and norepinephrine as neurotransmitters to regulate smooth muscle, cardiac muscle, and glands. The enteric nervous system forms nerve plexuses in the digestive tract walls and can function independently through local reflexes.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

CATARACTS.pptx
- 1. CATARACTS
- 2. CATARACTS Cataracts are the most common cause of vision loss in people age 40 and is the principal cause of blindness in the world. In fact,there are more cases of cataracts worldwide than there are of glaucoma, muscular degeneration and diabetic retinopathy.
- 3. TYPES OF CATARACTS SUBCAPSULAR CATARACT -occurs at the back of the lens .People with diabetes or those taking high doses of steroid medication have a greater risk of developing a subcapsular cataract.
- 4. NUCLEAR CATARACT-forms deep in the central zone (nucleus)of the lens. Nuclear cataracts usually are associated with aging.
- 5. CORTICAL CATARACT-is characterized by white, wedge-like opacities that start in the periphery of the lens and work their way to the center in a spoke-like fashion. This type of cataract occurs in the lens cortext,which is the part of the lens that surrounds the central nucleus.
- 7. RISK FACTOR Diabetes Smoking tobacco Prolonged exposure to sunlight Alcohol Increasing age Previous eye surgery
- 8. SIGN & SYMPTOMS Clouded, blurred or dim vision Increasing difficulty with vision at night Sensitivity to light and glare Need for brighter light for reading and other activities Seeing “halos” around lights Frequent changes in eyeglass or contact lens prescription Fading or yellowing of colors Double vision in a single eye
- 9. MEDICATIONS Some medication, such as systemic, topical, inhaled corticosteroids, may increase the risk of cataract development. Corticosteroids most commonly cause posterior subcapsular cataracts. People with schizophrenia often have risk factors for lens opacities(such as diabetes , hypertension ,and poor nutrition) but antipsychotic medications are unlikely to contribute to cataract formation. Miotics and triparanol may increase the risk.
- 10. SURGERY Is the removal of the natural lens of the eye(also called “crystalline lens”)that has developed an opacification , which is referred to as a cataract. Metabolic changes of crystalline lens fibers over time lead to the development of the cataract and loss of transparency, causing impairment or loss of vission.
- 11. CATARACT SURGERY Human with a slit lamp
- 12. TYPES OF SURGERY
- 13. Cataract surgery, using a temporal approach phacoemulsification probe (in right hand) and “chopper” (in left hand )being done under operating microscope.
