Wrinkles, creaky elbows, and silver hair aren't the solitary side effects old enough. Think about waterfalls, age-related macular degeneration (ARMD), and glaucoma, which are additional age-related issues that can harm vision. What you should know: While they are more continuous in individuals 50 and over, they are not really present.
To maintain your lifestyle, taking care of your eyesight is important. At least 1 in 6 adults aged 45 or older suffer from eye disorders that threaten vision. The risk of vision changes increases with age.
According to a report from the American Academy of Ophthalmology (AAO), an estimated million in the world will develop an eye disease by the year 2020. Following are some helpful tips to help protect your eyesight as you age.
Glaucoma is a common eye disease that affects the optic nerve connecting the eye to the brain and if not detected and treated early can lead to permanent vision loss and blindness. It occurs when the drainage area at the back of the eye becomes blocked; causing fluid to build up and pressure inside the eye to increase. Vision loss starts to occur when the pressure inside the eye becomes too high and damages the optic nerve. According to The World Health Organization glaucoma is the second leading cause of blindness in the world and the leading cause of irreversible blindness.

Clearing the vision a general know how on cataractssamcoe08
A cataract is a damaging eye condition that clouds aperson’s eyesight. It affects the lens of an eye, the part responsible for focusing a person’s vision. As the cataract develops, the lens clouds gradually.
This was a lecture in the course "Significant Medical Conditions in Seniors" presented at Peer Learning in Chapel Hill, NC, USA in 2016 by Michael C. Joseph, MD, MPH.
A cataract is a dense, cloudy area that forms in the lens of the eye. A cataract begins when proteins in the eye form clumps that prevent the lens from sending clear images to the retina. The retina works by converting the light that comes through the lens into signals. It sends the signals to the optic nerve, which carries them to the brain.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
Title: Sense of Smell

Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

2. What is Cataracts?
A cataracts is diseases which affect the eye as a
cloudy lens in the eye that may lead you too
blindness. The lens which form on the eye is
painless that’s the reason we can’t identify the
problem of the eye. It a process which take the
time, its work slowly as the you grow up. Mostly the
cataracts affects the eye after the age of 65. in
some case of cataracts it include the diseases like
diabetes, insomnia and skin cancer, radiation
weathering. A cataracts can take place in one eye or both the eyes.
It can’t spread from one eye to other.
Cataracts are grow inside the eye as an outer layer of the lens. Its stop the lights which comes
to the eye which make the person difficult to see the thing properly and it may occur the
blindness
to you. In term of Cataracts they are in progressive, it means that the continuously grow with
the time. In some case it has affected the young age people too.
3. Symptoms of Cataracts
Foggy vision or bleary vision
Glower or angry stare
Double Vision or a vivid mental image look twice.
Color changes or its look like multicolored,
a mixer of different colors.
Second Sight or movement overlook,
means seeing the things again and again.
New Prescription, means change in you eye wear.
4. What are the Causes of Cataracts?
The cataracts develop them when the glutenin grows in the lens of your eyes
, and it make the vision cloudy. Its not said that why the cataracts causes it
does not know, but the legible reason is aging is the risk factor. The other
symptoms may play the role in the development of the cataracts include:
Smoking
Excessive use of alcohol
Diabetes
Trauma to the eyes
Extended use of corticosteroids
Prolonged radiation or sun exposure
Age related
Congenital
Secondary
