Pre-Surgery Testing - Do You Think It Is Important?

Any patient who needs to undergo cataract surgery must be evaluated in a thorough manner so as to establish the requirement, appropriateness, expected surgical problems, expected benefits and co-morbid conditions having an influence on cataract surgery.

The preoperative assessment consists of -

A test for your existing glasses prescription:

It is useful for your cataract surgeon to know your existing glasses prescription in cases where there is a high refractive error (people who are very short or long sighted), in order to plan to correct this error after cataract surgery.

A full ocular examination: This includes looking at:

  • The eyelid anatomy and inflammation.
  • The state of the tear film, dry eye changes could make surgery difficult
  • The presence of abnormalities in the cornea that could make visualisation of the cataract difficult during surgery.
  • The amount of dilation the iris undergoes with dilating drops.
  • The type of cataract. Soft cataracts can be aspirated. Hard cataracts need more ultra-sound energy and surgical time to break up and remove. White cataracts may need trypan blue staining to visualize the capsule
  • The measurement of intra-ocular pressure. With this test, we aim to exclude glaucoma and ensure optimal control of immediate pre-operative and intra-operative eye pressures often with extra eye drops that temporarily lower eye pressure.

Biometry Tests: This is a simple pre-operative measurement. It calculates the correct power of artificial intra-ocular lens. They will be implanted into your eye once your cataract is removed.

Corneal Topography: This is a test to map out the corneal curvature in greater detail. It is used prior to premium IOL Implantation like Toric IOLS either monofocal or multifocal , to ensure avoid postoperative refractive errors. This extra test is only required if the biometry readings show larger than normal differences in keratometry readings.

Optical Coherence Tomography (OCT): This test allows detailed visualisation of the macula (the central sensitive part of the retina used for fine vision). If the ophthalmologist suspects any macula changes that may prevent a patient from visual improvement after cataract surgery, he always suggest optical coherence tomography.

Blood Pressure Measurements: It is very important to know your blood pressure measurements before your cataract operation. The risk of having a bleed at the back of your eye during cataract surgery (supra-choroidal haemorrhage) is very small (1 in 10000). But is higher if you have uncontrolled blood pressure.

Blood Sugar Measurements in Diabetic Patients: Cataract surgery itself does not affect your blood sugar measurements if you are diabetic. A routine checkup of blood sugars in diabetics before cataract surgery is done and the surgery if often delayed if the levels were greater than 20mmol/L as the risk of post-operative infection is higher.

In case you have a concern or query you can always consult an expert & get answers to your questions!

Why It Is Important To Get Your Eyes Tested Regularly?

Why It Is Important To Get Your Eyes Tested Regularly?

Sight is one of our most important senses. To ensure that your vision is not compromised, regular eye examinations are essential. This is regardless of age and overall health because the only way to diagnose conditions in the eye in the early stages is with a comprehensive eye exam. By arresting them in the early stages, many eye disorders can be easily controlled and treated.

During a routine eye examination, the doctor will look into a number of aspects of your eye's health. An eye examination can also indicate serious health issues like diabetes, macular degeneration and glaucoma. Some of the conditions an eye doctor looks for during an eye exam are:

Refractive error
If you already have a prescription this will be checked. In other cases, the strength of the eye muscles is checked for near sightedness, far sightedness and astigmatism which can be corrected with lasik surgery, spectacles or lenses. The earlier a refractive error is corrected, the lower are its chances of increasing. When it comes to children, they often do not realize signs of vision deterioration and hence, an eye examination becomes essential.

Amblyopia
This is a condition where one eye has a much higher refractive error than the other or where the eyes are misaligned. If this is not treated in time, amblyopia can stunt vision in the affected eye and result in blindness.

Strabismus
Crossed or turned eyes are termed as cases of strabismus. This is caused by the misalignment of the eyes and can cause problems with depth perception. This can lead to amblyopia and eventual blindness if not treated in time.

Focusing and communicative problems between the eyes
An eye examination can also determine problems with focusing on objects. With children this can be a sign of underdeveloped focusing skills while in adults it can be a symptom of presbyopia or age related diminished focusing ability. Your doctor will also check how well your eyes work together. If they do not work in tandem, it can cause headaches, eye strains and problems with reading.

Diseases
By looking at the blood vessels and retina of the eyes, doctors can detect signs of high blood pressure, cholesterol etc. Leaks in the blood vessels or bleeding in the eyes can also be a sign of diabetes or swelling of the macula.

Age related conditions
As with the rest of the body, the eye tissues and muscles also degenerate with time. Cataract is one of the most common age related issues that affect the eyes. In case you have a concern or query you can always consult an expert & get answers to your questions!

Why Vitamin B Is Important?

Vitamin B is not one vitamin, but is a complex of 8 vitamins, which not only essential for a good health, but also enables smooth functioning of various functions of the body. Further, each of the vitamin B complexes has specific body functions ranging from iron metabolism to hair health to preventing migraineOur body requires vitamin substances, as stated by their names.

  • Vitamin B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6, B7 (biotin), B9 (folate), B12.
  • Vitamin B complex is widely present in food sources, and in someone who eats a well-balanced diet would be getting the required amounts of vitamin B complex.
  • Vitamin B1, also known as thiamine, is required for the body to make new cells and so has a significant role in the immune system. It ias also known as the anti-stress vitamin as it helps in improving immunity. It also is required for breakdown of carbohydrates.
  • Vitamin B2, chemically known as riboflavin, is essential for red blood cell production and transporting oxygen throughout the body. It also has antioxidant properties by reducing free radicals. This also has antiaging properties and reduces the onset of heart disease.
  • Vitamin B3, also known as niacin, is essential for cholesterol regulation. It promotes the formation of good cholesterol and so essential for preventing the onset of heart disease. It also is shown to have anti-acne effects.
  • Vitamin B5, pantothenic acid, is essential for fat and carbohydration metabolism. It also is required for the production of hormones including testosterone and cortisol (stress hormones). It is also beneficial to the skin by reducing antiaging effects including reducing brown spots.
  • Vitamin B6 or pyridoxine, has a major role to play in sleep and mood regulation. It produces various neurotransmitters like serotonin, melatonin, and norepinephrine which are essential for emotional well-being. It also has anti-inflammatory properties and is useful in conditions like rheumatoid arthritis.
  • Vitamin B7 or Biotin is known as the beauty vitamin, as it has major hair, skin, and nail benefits. It is also essential for glucose level maintenance. It assumes great importance in pregnancy as it is important for normal growth of the baby.
  • Vitamin B9 or folate or folic acid is again very essential in pregnancy as deficiency can lead to neurological defects in the developing baby. It also plays a major role in carrying oxygen to the cells through the RBCs.
  • Vitamin B12 or cobalamin is essential to ensure the other vitamins are functioning properly. B12 deficiency leads to anaemia, as it enables the red blood cells to carry oxygen throughout the body. It is mostly present in non-vegetarian foods and supplements are commonly given in anaemic people.

STDs - Why Regular Testing Is Important?

STIs or sexually transmitted diseases are infections whose transmission to a healthy person from an infected person happens through sexual contact. However, with modern medicine and diagnostic techniques, there are ways to prevent, detect and cure them effectively and quickly.
Not all diseases are curable though and it is best to follow preventive measures. Also, for sexually active adults it is an absolute necessity to get tested regularly for their health as well as the well-being of their partners.
Why do people tend to avoid getting tested for STIs or sexually transmitted infections?
One of the major factors that avert people from regular tests is the social stigma attached with sexually transmitted diseases. It is absolutely imperative for sexually active adults to go for regular checkups so that if they have any infections or diseases, it can be diagnosed quickly and remedial measure can be taken appropriately.
The benefits of regular checkups
Some of the benefits of regular checkups are mentioned here:-

  • Regular checkups can detect problems at a stage when the conditions may not have progressed too much and this will make it easily treatable.
  • With HIV positive patients, the quicker the testing gets done the quicker the treatment can be started. Thus, can prevent the onset of AIDS.
  • Regular checkups can control the progression of the diseases such as Chlamydia, which if left untreated can cause permanent infertility.
  • Getting a prospective partner tested is also a good idea as this can enable one to protect themselves from STIs.
  • Symptoms for certain STIs can be similar to many other non-sexual or non-venereal diseases. Thus getting tests done is the only way to get to know if there is an STI or if it is some other nonsexual disease.
  • HPV or Human Papilloma Virus can be detected easily with regular STI checkups and thus appropriate treatment can be started. If HPV isn't detected early, it can manifest much later in the form of cancer, which makes it more important to get yourself checked early on. If you wish to discuss about any specific problem, you can consult a Sexologist.

Why Insulin Is Important?

Why Insulin Is Important?

Insulin is a hormone that is important for metabolism and utilization of energy from the ingested nutrients like carbohydrate, fat and protein. Insulin is synthesized in significant quantities only in beta cells in the pancreas. It is secreted primarily in response to elevated blood concentrations of glucose. Insulin thus can regulate blood glucose and the body senses and responds to rise in blood glucose by secreting insulin. 

Other stimuli like sight and taste of food, nerve stimulation and increased blood concentrations of other fuel molecules, including amino acids and fatty acids, also promote insulin secretion. Insulin has several broad actions including: 

  1. It causes the cells in the liver, muscle, and fat tissue to take up glucose from blood and convert it to glycogen that can be stored in the liver and muscles 
  2. Insulin also prevents the utilization of fat as an energy source. In absence of insulin or in conditions where insulin is low glucose is not taken up by body cells, and the body begins to use fat as an energy source 
  3. Insulin also controls other body systems and regulates the amino acid uptake by body cells 
  4. It has several other anabolic effects throughout the body as well Since insulin controls the central metabolic processes, failure of insulin production leads to a condition called diabetes mellitus

There are two major types of diabetes – type 1 and type 2. 

Type 1 diabetes, occurs when there is no or very low production of insulin from the pancreatic beta cells. Patients with Type 1 diabetes mellitus depend on external insulin (most commonly injected subcutaneously) for their survival. 

In type 2 diabetes, mellitus the demands of insulin are not met by the amount produced by the pancreatic beta cells. This is termed insulin resistance or ''relative'' insulin deficiency. These patients may be treated with drugs to reduce their blood sugar or may eventually require externally supplied insulin if other medications fail to control blood glucose levels adequately.

Trying To Have A Baby - Get These Basic Tests Done!

Trying To Have A Baby - Get These Basic Tests Done!

One of the best news what a couple can have is to expect the arrival of a baby. With changing lifestyles, most people have chosen to have a baby much later in life, with education and career taking priority. However, when the couple is ready and it does not happen, there can be a lot of anxiety and stress.

It is normal for couples to take about 4 to 6 months to conceive, and there are various factors which can affect this. It is important to consider that the issue could be with either partner and so both need to be involved in testing to find out the underlying reasons.

When you have decided to check with a doctor, the following will be considered.

  1. The health conditions of both parents including lifestyle (tobacco, alcohol, diet patterns, weight, etc.)
  2. Medical history including medications
  3. Any history of infertility that runs in the family
  4. Sexual history including sexual health, STDs, painful sex
  5. Gynecologic history of female including any menstrual disorders or pelvic diseases like endometriosis
  6. Any issues with the male partner including erection or ejaculation
  7. Reproductive history including prior children, prior pregnancies, miscarriages

Some of the most common tests that would be done are listed below, separately for women and men.
Women: A physical exam will also include checking the pelvic area for any obvious signs of fibroids, cysts, PID, or endometriosis. This is followed by one or more of the following tests as required for the diagnosis of the underlying cause.

  1. A cervical smear test to test the vaginal and cervical environment
  2. Blood test to test for rubella infection, varicella or chickenpox
  3. Blood test to check for ovulation. This is done 7 days before the period and evaluates both whether ovulation is happening and other correlated factors like temperature, cervical mucus, quality of the egg
  4. Blood test to check for hormonal levels including FSH, prolactin, thyroid hormone, testosterone, and progesterone. Each of these plays a vital role in the entire pregnancy cycle, and so should be evaluated
  5. Urine test for chlamydia, which can cause infertility
  6. Scanning to check for the internal structures like fallopian tubes, uterine lining, and cervix.

Men:

  1. The first step is to understand if there is a sexual problem including erection and/or ejaculation
  2. A physical exam is done to look for swellings in the scrotum
  3. Blood test to check for hormonal levels, especially testosterone.
  4. Sperm analysis including quantity, quality, and motility of sperms. This is one of the easiest tests to do and should be done even before more elaborate tests are done in the female.

Involving both the partners is very important to solve this problem. If you wish to discuss about any specific problem, you can consult a Gynaecologist.
