This document provides an overview of glaucoma, including what it is, its causes and risk factors, types of glaucoma, symptoms, treatments and prevention. Glaucoma is caused by a buildup of fluid pressure in the eye that damages the optic nerve if not treated. It is usually treated initially with eye drops but may require surgery if drops are not effective. Regular eye exams are important for early detection and treatment to minimize vision loss.
Glaucoma is a group of eye conditions that damage the optic nerve, the health of which is vital for good vision. This damage is often caused by an abnormally high pressure in your eye.
Glaucoma is one of the leading causes of blindness for people over the age of 60. It can occur at any age but is more common in older adults.

Glaucoma is the name for a group of eye conditions in which optic nerve is damaged at the point where it leaves the eye. This nerve carries information from the light sensitive layer, the retina, to the brain where it is perceived as a picture.
In some people, the glaucoma damage is caused by raised eye pressure. Others may have an eye pressure within normal limits but damage occurs because there is weakness in the optic nerve.
Different types of Glaucoma
Open angle glaucomas (chronic glaucoma): It is most common. The eye is anatomically normal, but blockage or malfunction of the drainage channels slowly over many years causes elevated eye pressure. There is no pain but the field of vision gradually becomes impaired. We need to use chemical cleaner (eye drops) to open the drain or turn down the faucet. If this is insufficient, we can stake the drain (laser trabeculoplasty) & if that doesn’t work. We need to put in new plumbing (surgery / implants)
Angle closure glaucoma (Acute glaucoma): The trabecular meshwork is normal, but the iris is pushed against the meshwork & there is sudden and more complete blockage to the flow of aqueous. It means the drainage channels are covered by a stopper & we need to remove the stopper (laser iridotomy). This glaucoma can be quite painful & will cause permanent damage to sight if not treated promptly. Glued iol surgery in indore with best doctors at glaucoma treatment hospital in indore.
Secondary and developmental glaucoma: When a rise in eye pressure is cause by another eye condition it is called secondary glaucoma. Glaucoma in childhood is called developmental or congenital which is caused by malformation in the eye.
Risk factors
> Hypertension
> Diabetes
> People over the age of 45.
> People with family history of glaucoma.
> People with myopia are more prone to develop open angle glaucoma & those with hyperopia are more prone to develop angle closure.
Warning Signs of Glaucoma

Glaucoma is a group of eye diseases which result in damage to the optic nerve and cause vision loss.
Congenital (Buphthalmos): Congenital glaucoma (CG) is a developmental glaucoma that results from the abnormal development of the aqueous drainage structure, characterized by an elevated intra-ocular pressure, enlargement of globe (buphthalmos), corneal edema and optic nerve cupping, and presenting clinically with the characteristic triad of epiphora, photophobia and blepharospasm.
Glaucoma is one of the leading causes of blindness for people over the age of 60.

Glaucoma can occur at any age but is more common in older adults. It is one of the leading causes of blindness for people over the age of 60.
Many forms of glaucoma have no warning signs. The effect is so gradual that you may not notice a change in vision until the condition is in its later stages.
It's important to have regular eye exams that include measurements of your eye pressure. If glaucoma is recognized early, vision loss can be slowed or prevented. If you have glaucoma, you'll need treatment or monitoring for the rest of your life.

When to see a doctor
If you experience symptoms that come on suddenly, you may have acute angle-closure glaucoma. Symptoms include severe headache and severe eye pain. You need treatment as soon as possible. Go to an emergency room or call an eye doctor's (ophthalmologist's) office immediately.Causes
Glaucoma develops when the optic nerve becomes damaged. As this nerve gradually deteriorates, blind spots develop in your vision. For reasons that doctors don't fully understand, this nerve damage is usually related to increased pressure in the eye.
Elevated eye pressure happens as the result of a buildup of fluid that flows throughout the inside of the eye. This fluid also is known as the aqueous humor. It usually drains through a tissue located at the angle where the iris and cornea meet. This tissue also is called the trabecular meshwork. The cornea is important to vision because it lets light into the eye. When the eye makes too much fluid or the drainage system doesn't work properly, eye pressure may increase.
Open-angle glaucoma
This is the most common form of glaucoma. The drainage angle formed by the iris and cornea remains open.

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.

India Clinical Trials Market: Industry Size and Growth Trends [2030] Analyzed...Kumar Satyam
According to TechSci Research report, "India Clinical Trials Market- By Region, Competition, Forecast & Opportunities, 2030F," the India Clinical Trials Market was valued at USD 2.05 billion in 2024 and is projected to grow at a compound annual growth rate (CAGR) of 8.64% through 2030. The market is driven by a variety of factors, making India an attractive destination for pharmaceutical companies and researchers. India's vast and diverse patient population, cost-effective operational environment, and a large pool of skilled medical professionals contribute significantly to the market's growth. Additionally, increasing government support in streamlining regulations and the growing prevalence of lifestyle diseases further propel the clinical trials market.
Growing Prevalence of Lifestyle Diseases
The rising incidence of lifestyle diseases such as diabetes, cardiovascular diseases, and cancer is a major trend driving the clinical trials market in India. These conditions necessitate the development and testing of new treatment methods, creating a robust demand for clinical trials. The increasing burden of these diseases highlights the need for innovative therapies and underscores the importance of India as a key player in global clinical research.
Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

2. What is glaucoma?
In short, glaucoma is a build up of pressure within the eye that causes damage to the optic nerve.
There is a small space in the front of the eye called the anterior chamber. Clear liquid flows in and out of
the anterior chamber, this fluid nourishes and bathes nearby tissues. If a patient has glaucoma, the fluid
drains too slowly out of the eye. This leads to fluid build-up, and pressure inside the eye rises.
Unless this pressure is brought down and controlled, the optic nerve and other parts of the eye may
become damaged, leading to loss of vision.
The disease usually affects both eyes, although one may be more severely affected than the other.
3. Treatments for glaucoma
Treatments involve either improving the flow of fluid from the eye, reducing its production, or both:
Eyedrops for glaucoma
In the majority of cases, initial treatment for glaucoma includes eye drops.
Compliance is vital for best results and to prevent undesirable side effects - this means following the
doctor's instructions carefully.
Examples of eyedrops include:
prostaglandin analogues
carbonic anhydrase inhibitors
cholinergic agents
beta blockers
Side effects of eyedrops can include stinging, redness, eyelash growth, change in eye color and
occasionally retinal detachments and difficulty breathing. If eyedrops are not effective enough, the doctor
may prescribe an oral carbonic anhydrase inhibitor.
Side effects are less if they are taken during meals. Initial side effects can include tingling in the fingers and
toes and frequent urination - however, after a few days, they usually resolve.
Much less commonly, there is a risk of rashes, kidney stones, stomach ache, weight loss, impotence,
fatigue, and a strange taste when consuming fizzy drinks.
4. Causes of glaucoma
Experts are unsure of the precise causes of glaucoma, but cases are divided into two categories:
Primary glaucoma - this means that the cause is unknown.
Secondary glaucoma - the condition has a known cause, such as a tumor, diabetes, an advanced cataract,
or inflammation.
There are several risk factors for glaucoma:
Old age.
Ethnic background - East Asians, African Americans, and those of Hispanic descent have a higher risk of
developing glaucoma, compared with Caucasians.
Some illnesses and conditions - like diabetes or hypothyroidism.
Eye injuries or conditions.
Eye surgery.
Myopia (nearsightedness).
Corticosteroids
Patients on long-term corticosteroids have a raised risk of developing several different conditions,
including glaucoma. The risk is even greater with eye drops containing corticosteroids.
5. Types of glaucoma
There are two main types: open-angle and closed-angle glaucoma.
Closed-angle glaucoma (acute angle-closure glaucoma)
This can come on suddenly; the patient commonly experiences pain and rapid vision loss. Fortunately, the
symptoms of pain and discomfort make the sufferer seek medical help, resulting in prompt treatment,
which usually prevents any permanent damage from occurring.
Primary open-angle glaucoma (chronic glaucoma)
This type progresses very slowly. The patient may not feel any symptoms; even slight loss of vision may go
unnoticed. In this type of glaucoma, many people do not get medical help until permanent damage has
already occurred.
Low-tension glaucoma
This is a rarer form of glaucoma that experts do not fully understand. Even though eye pressure is normal,
optic nerve damage still occurs. It might be due to reduced blood supply to the optic nerve.
Pigmentary glaucoma
This is a type of open angle glaucoma and typically develops during early or middle adulthood. Pigment
cells, which arise from the iris, are dispersed within the eye. If these cells build up in the channels that drain
fluid from the eye, they can upset the normal flow of fluids in the eye, leading to a rise in eye pressure.
6. What are the symptoms of glaucoma?
The signs and symptoms of primary open-angle glaucoma and acute angle-closure glaucoma are quite
different:
Symptoms of primary open-angle glaucoma
• Peripheral vision is gradually lost. This nearly always affects both eyes.
• In advanced stages, the patient has tunnel vision.
Symptoms of closed angle glaucoma
• Eye pain, usually severe.
• Blurred vision.
• Eye pain is often accompanied by nausea and sometimes vomiting.
• Lights appear to have extra halo-like glows around them.
• Red eyes.
• Sudden, unexpected vision problems, especially when lighting is poor.
7. Surgery for glaucoma
If drugs don't work, or if the patient cannot tolerate them, surgical intervention may be an option. The
aim of surgery is usually to bring down the pressure inside the eye. Examples of surgery include:
• Trabeculoplasty - a laser beam is used to unblock clogged drainage canals, making it easier for the
fluid inside the eye to drain out.
• Filtering surgery (viscocanalostomy) - this may be carried out if nothing else works, including laser
surgery. Channels within the eye are opened up to improve fluid drainage.
• Drainage implant (aqueous shunt implant) - this option is sometimes used for children or those with
secondary glaucoma. A small silicone tube is inserted into the eye to help it drain out fluids better.
8. Acute angle-closure glaucoma
Acute angle-closure glaucoma is treated as a medical emergency. Pressure-reducing medications are
administered immediately. A laser procedure is usually carried out that creates a tiny hole in the iris,
allowing fluids to pass into the trabecular meshwork (the drainage system of the eye) - this procedure is
called an iridotomy.
Even if only one eye is affected, the doctor may decide to treat both, because this type of glaucoma often
affects the other eye, too.
9. Prevention
There is no known way to prevent glaucoma, but catching it early means it can be treated more effectively
and vision loss can be minimized. Because, often, there are no symptoms, getting your eyes regularly
checked is important; especially for people with a greater risk.
So, older adults, people of African descent, and individuals with diabetes should be tested every year or 2
after the age of 35. Ask a doctor how often you should have a check up.
