SERVICES OFFERED

COMPUTER EYE TESTING

Comprehensive eye testing goes a long way in correcting your vision and helping you see things clearly. Gone are the days that everything needs to be done manually. With the advent of computerized eye testing, it has become easy and cost-effective to test for errors in sight and prescribe corrective lenses.

CATARACT

A cataract is a process whereby the clear crystalline lens of the eye becomes cloudy, leading to visual impairment. Though, usually a condition of old age, it may occur in children and young adults too. At Kanishk Hospital, We do cataract surgery  Via, Visalis 100,   Carl Zeiss Phacoemulsification machine, intending to provide the best care cost-effectively.

  • High blood sugars damage retinal blood vessels resulting in vision loss. Strict control of blood sugars helps in preventing any vision loss.
  • Associated blood pressure, anemia (low hemoglobin), kidney problems or high cholesterol levels increase the diabetic damage to the eye.
  • Visit an eye doctor regularly. If treated early, vision loss in diabetes can be avoided.
  • Exercise regularly
  • Eat plenty of green vegetables.
  • Stop smoking, alcohol and tobacco use.

How is diabetic retinopathy treated?

Treatment depends on the stage at which the patient presents to us.

  • In early stages, controlling the blood sugar levels and other parameters helps
  • Some patients may need drops or injections to reduce the retinal swelling and slow the vision loss and perhaps even improve the vision.
  • Retinal Lasers may be needed to seal off the leaking vessels. This can help in reducing the swelling of the retina. Sometimes more than one sitting of laser is needed
  • Retinal surgery may be needed in advanced cases of diabetic retinopathy to remove blood or scar tissue from the eye.

GLAUCOMA

Glaucoma is an eye disease that can damage your optic nerve. The optic nerve supplies visual information to your brain from your eyes. Glaucoma is usually, but not always, the result of abnormally high pressure inside your eye. Over time, the increased pressure can erode your optic nerve tissue, which may lead to vision loss or even blindness. If it’s caught early, one may be able to prevent additional vision loss.

Symptoms

The most common type of glaucoma is primary open-angle glaucoma. It has no signs or symptoms except gradual vision loss. For that reason, it’s important that yearly comprehensive eye exam with an ophthalmologist should be done to monitor any changes in your vision.
Acute-angle closure glaucoma, which is also known as narrow-angle glaucoma, is a medical emergency. Comprising of symptoms:

  • severe eye pain
  • Nausea
  • Vomiting
  • Redness in your eye
  • Sudden vision disturbances
  • Seeing colored rings around lights
  • Sudden blurred vision

Cause

The back of the eye continuously makes a clear fluid called aqueous humor. As this fluid is made, it fills the front part of the eye. Then, it leaves the eye through channels in the cornea and iris. If these channels are blocked or partially obstructed, the natural pressure in the eye, which is called the intraocular pressure (IOP), may increase. As IOP increases, optic nerve may become damaged. As damage to nerve progresses, one may begin losing eyesight. What causes the pressure in the eye to increase isn’t always known. However one or more of these factors may play a role:

  • Blocked or restricted drainage in your eye
  • Medications, such as corticosteroids
  • Poor or reduced blood flow to your optic nerve
  • High or elevated blood pressure

Types

Five major types of glaucoma exist:

  • Open-Angle (Chronic) Glaucoma This glaucoma has no signs or symptoms except gradual vision loss. This loss may be so slow that the vision can suffer irreparable damage before any other signs become apparent.
  • Angle-Closure (Acute) Glaucoma If the flow of the aqueous humor fluid is suddenly blocked, the rapid buildup of fluid may cause a severe, quick, and painful increase in pressure. Angle-closure glaucoma is
  • Congenital Glaucoma Children born with congenital glaucoma have a defect in the angle of their eye, which slows or prevents normal fluid drainage. Congenital glaucoma can run in families.
  • Secondary Glaucoma Secondary glaucoma is often a side effect of injury or another eye condition, such as cataracts or eye tumors.
  • Normal Tension Glaucoma In some cases, without increased in eye pressure damage to their optic nerve developes. The cause of this isn’t known

Risk Factors

  • Age- >60 years
  • Eye Problems- Chronic eye inflammation, Physical injury or trauma and thin corneas.
  • Family History
  • Medical History- diabetes, high blood pressure and heart disease
  • Medicine- corticosteroids for extended periods may increase your risk of developing secondary glaucoma.

Diagnosis

  • Detailed Medical History
  • Any personal or family history of glaucoma to determine if any other health conditions may be impacting your eye health, such as diabetes or high blood pressure.
  • Tonometry Test
  • Measures intra ocular pressure.
  • Pachymetry Test
  • Done to measure corneal thickness.
  • Perimetry Test
  • This test, also known as a visual field test. This test is done to measure the peripheral, side and central vision.
  • OCT Optical Coherence Tomography
  • This is done to find out the level of damage to the optic nerve.

Treatment

  • The goal of glaucoma treatment is to reduce IOP to stop any additional eyesight loss. Treatment options include:
  • Medications
  • Several medicines are designed to reduce IOP. These medicines are available in the form of eye drops or pills, but the drops are more commonly used or a combination of these.
  • Surgery
  • If a blocked or slow channel is causing increased IOP, surgery to maybe needed to drain the path for fluid or destroy tissues that are responsible for the increased fluid.
  • Laser
  • A laser procedure called laser peripheral iridotomy may also be performed for narrow angle glaucoma patients. This procedure creates small holes in the iris to allow for increased fluid movement.

Prevention

If increased in IOP can be stopped and the pressure returned to normal, vision loss may be slowed or even stopped. However, because there’s no cure for glaucoma, one may likely need treatment for the rest of the life to regulate IOP. Unfortunately, vision lost as a result of glaucoma cannot be restored. Glaucoma can’t be prevented, but it’s still important to catch it early so that one can begin treatment that will help prevent it from getting worse. The best way to catch any type of glaucoma early is to have an annual preventive eye care appointment.

RETINA

Ophthalmology Department at Sharda is geared to deal with several retinal diseases like Diabetic Retinopathy, Macular Edema, CSR, Age-Related Macular Degeneration, and various vascular diseases of the retina.

What is diabetic retinopathy

People with diabetes can have an eye disease called diabetic retinopathy. This is when high blood sugar levels cause damage to blood vessels in the retina. These blood vessels can swell and leak or they can close, stopping blood from Passing through. Sometimes abnormal new blood vessels grow on the retina. All of these changes can decrease your vision.

Stages of diabetic retinopathy

There are 2 main stages of diabetic eye disease

NPDR (Non Proliferative Diabetic Retinopathy) This is an early stage of diabetic eye disease. In NPDR, the blood vessels leak causing swelling of the retina. This swelling is called macular edema. This is the most common cause of vision loss in diabetics.

In some cases of NPDR, blood vessels in the retina can close off. This is called macular ischemia.

PDR (Proliferative Diabetic Retinopathy) This is a more advanced stage of diabetic eye disease. In this stage, there is a growth of new blood vessels into the retina. This is called neo-vasculaisation. These fragile new vessels often bleed into the eye. If the bleed is less, the patient sees a few dark floaters. If the bleed is more, it can block all vision.

What are diabetic retinopathy symptoms?

You can have diabetic retinopathy and not know it. This is because it often has no symptoms in its early stages. As diabetic retinopathy gets worse, you will notice symptoms like

  • Seeing more number of floaters
  • Having blurry vision
  • Having vision that changes sometimes from blurry to clear
  • Seeing blank or dark areas in your field of vision
  • Having poor night vision
  • Noticing colours appear faded or washed out
  • Losing vision Diabetic retinopathy symptoms usually affect both eyes

How is diabetic retinopathy diagnosed?

Diabetic retinopathy is diagnosed by a good clinical examination using special lenses to look into your eye. Sometimes an OCT test may be needed to give a better idea of the
extent of the disease. The machine scans the retina and provides detailed information of the thickness and changes in the retina.

  • Seeing more number of floaters
  • Having blurry vision
  • Having vision that changes sometimes from blurry to clear
  • Seeing blank or dark areas in your field of vision
  • Having poor night vision
  • Noticing colours appear faded or washed out
  • Losing vision Diabetic retinopathy symptoms usually affect both eyes.
