Ophthalmology is the branch of medical science dealing with the anatomy, function, pathology, and treatment of the eyes.
Healthcare providers dealing with ophthalmology fall under three categories-
An ophthalmologist is a physician who specializes in the medical and surgical care of the eyes and visual system and the prevention of eye disease and injury.
An optometrist is a health service provider who deals with vision-related problems.
An optician is a technician who deals in optical devices. They validate and provide lenses, frames,and other specially fabricated optical devices or contact lenses based upon prescription to the intended wearer.
Ophthalmology treatments in India cover numerous eye conditions and other vision-related disorders.
It is a chronic, progressive optic neuropathy caused by a group of ocular conditions that lead to damage of optic nerve with loss of visual function. The most common risk factor known is raised intraocular pressure (pressure of the eye which can be measured by an instrument).
Normal intraocular pressure = 10–20 mm Hg (Schiotz)
Treatment options include:
Diabetic retinopathy refers to the retinal changes that occur in patients with diabetes mellitus (people with abnormally high blood sugar).
Symptoms of Diabetic Retinopathy are:
With an increase in life expectancy in diabetic patients, the incidence of diabetic retinopathy has increased. It is the leading cause of blindness, particularly in an affluent society. It is common after the disease has lasted approximately 10 years.
It usually occurs in patients after the age of 20 years. It affects young or old alike because it is the diabetic age and not the actual age that is important. Treatment options include adequate medical control with low fat, laser, surgery and intravitreal medication
Age-Related Macular Degeneration (ARMD):
It is also known as senile macular (small area of the retina in the eye) degeneration. It is an age-related, bilateral, non-hereditary degeneration.
Treatment options are:
Tumors Of The Retina Retinoblastoma (Glioma Retinae):
It is a common congenital malignant tumor of the retina occurring in early childhood. It is due to the proliferation of neural cells that have failed to evolve normally. Treatment options are chemotherapy, Enucleation Radiation, and cryotherapy.
Retinal Detachment (Separation Of The Retina):
Retinal detachment is a serious eye disorder and happens when a layer of tissue at the back of the eye that processes light pulls away from the tissue around it. The retina is unable to work properly when this happens. Retinal detachment can cause permanent vision loss if not treated in the right way. A disconnected retina doesn't hurt.
The symptoms include:
The main principle of treatment is to approximate and adhere to the torn part of the retina to an area of other layers of the eye via Photocoagulation and cryosurgery.
It is a refractive error in which the eye is unable to bend (refract) light properly. A patient can look close objects clearly, but the distant objects appear blurred.
Myopia can be treated either by spectacles or through the operative procedures.
Treatment Options include:
Spectacles—Myopia is treated by prescribing suitable correcting spherical concave lenses for constant use
Refractive surgery: The cornea is reshaped using a laser beam which helps in reducing the refractive error. Lesnes or eyeglasses may be needed even after the surgery
Any opacity in the lens or its capsule, whether developmental or acquired, is called a cataract.
Treatment options include:
Other optical procedures include:
Other Eye Surgeries:
How is glaucoma harmful to vision?
Glaucoma can cause vision loss, and it can decrease the amount and quality of information sent to the brain. Glaucoma affects or damagesthe optic nerve at the back of the eye.
Will someone go blind from glaucoma?
It depends on the type of treatment and stage of diagnosis. If diagnosed at an early stagewith proper treatment, glaucomacan be controlled with less or no future vision loss. If in case left untreated,then it will first affect peripheral vision then central vision and causes blindness.
What are the preparation for cataract surgery?
A week before your surgery, your doctor will conduct some tests to measure thedimensions of your eye, like size and shape. The tests will help himto select the best artificial lens for your eye. Just before the surgery,he will tell you not to eat and drink anything for 12 hours.
What should I do if my vision gets blurred or cloudy after cataract surgery?
Your doctor may recommend the YAG procedure to clear up your cloudy vision. In the YAG procedure, the surgeon uses a laser to open the coagulatingaround the lens; this will let more get through your artificial lens and hence, clear your cloudy vision.
How Soon Can I Drive After Cataract Surgery?
This totally depends on your condition like ageand stage of cataract. It is better to consult your surgeon. He will evaluate your vision and tell you when it’s safe for you to drive.
Is diabetic retinopathy curable?
The treatment can slow the growth of diabetic retinopathy, but it is less likely to reverse any vision loss. It is not completely curable.
What are diabetic retinopathy treatments currently available?
The best and most affordable treatment is to keep your diabetes and blood pressure under control.
