Bionic eye implants, augmented reality, 3D-printed digital contact lenses, so much has been happening in the world of eye care. In fact, the future of vision and eye care is surrounded by science-fiction powered by digital technology with health apps pouring from all sides.
Above 80-percent perception comes through vision
Researchers estimated that 80-85 percent of human perception, learning, activities and cognition are directly mediated through vision. Compared to that, hearing only covers 11-percent of the information whereas smell accounts for 3.5-percent and taste only one-percent.
It’s pretty much possible only if you can imagine being in the middle of an open field with clear skies and sunshine above and humming of the bees in distant air. How far can you hear and how far can you see? Obviously, vision can easily take a wide view as compared to hearing that’s limited to hardly 10-20 metres maximum.
Consider it almost a cliché emphasising the importance of eyes and vision with the above being the simplest example of one of the most important sensory organs of human. Ask those who catch an eye disease and their urge to get it cured ASAP!
Eye conditions, worldwide affects rising
In 2015, the International Agency for the Prevention of Blindness estimated that approximately 36-million people around the world are blind with more or less 217-million suffering from mild to severe distance vision impairment. Comparing the statistics with 1990, the prevalence of blindness and vision impairment has dropped from almost 4.6 to 3.6-percent as in 2015. This can be attributed to advancement in technology, the coming of new surgical techniques and various health apps for rightful treatment of the many eye infections and even to find a doctor in the UAE.
Digital technology is playing an active role for reducing vision related ailments with the very field of ophthalmology being transformed in the past few years. New and innovative solutions are now offered for a variety of eye diseases whereby treating minor ailments has accelerated with targeted and more efficient solutions.
Bionic eyes to reverse blindness
Creative minds and visionaries in Ophthalmology experienced a boost with advanced technologies. In fact, certain conditions that can actually result in blindness such as AMD or retinitis pigmentosa; an inherited eye issue that cause gradual loss of sight and eventual blindness has been successfully treated using latest tech and medical findings.
Development of implantable visual prosthetics for the restoration of vision amongst the blind due to retinitis pigmentosa actually happened in 2016 when blind women was fitted with a “bionic eye” in the Oxford Eye Hospital allowing her to see for the first time in six years.
A year earlier, that is in 2015, surgeons in Manchester carried the first bionic eye implant procedure on an 80-year old AMD patient who lost his entire central vision. The retinal implant however was unable to restore highly-detailed vision but the patient can actually recognise distinct patters such as shapes, door hinges and frames so on.
Artificial retina & brain implants
The Argus II device for helping people with retinitis pigmentosa for vision restoration cost around $150,000, only 250 of these are sold so far. Not very long before, a modified version has been underway which leaves the eye out and instead mobilises part of the brain that’s responsible for the processing visual information; the visual cortex.
It’s able to deliver electrical pulses thereby telling the brain to perceive light patterns. The innovation is geared to aid more than six-million blind people in future through various causes such as cancer, glaucoma, diabetic retinopathy and traumatic injury.
Now, instead of those “bionic eyes” stimulating brain cells with the lights coming from a micro video came or stimulation of the visual cortex directly through electrodes, a far more futuristic approach has been taken for the retinal degeneration that’s basically replacement of the damaged with an artificial retina. The results so far have been highly promising on lab rats whereas preliminary results on humans are expected to come out in 2018.
The role of health apps and technology in all this revolution couldn’t be overlooked! We’ll continue looking into remarkable reforms in vision and eye care in part two of the series.
Thyroid: Its Working, Symptoms, Effects
The Thyroid gland is a very small, butterfly-shaped gland in your body which is placed between your collarbone and the voice box. This gland is responsible for releasing the hormones which are responsible for regulating the metabolism rate in your body. Not only does it control the number of calories you burn, but also checks the speed of your working organs like heart, liver, kidney, brain and other organs. It also regulates the functioning of your body like heart rate, muscle strength, menstrual cycles, body temperature, breathing, weight, and much more.
As the thyroid gland is responsible for so many important functions, it is important that it should work properly and release hormones in the required number; not more, not less. The underactive thyroid is known as hypothyroidism and an overactive thyroid gland is called hyperthyroidism.
How does it work?
The thyroid glands produce the hormones with the help of iodine present in our body and release these hormones into the blood which takes it to the cells in our body. This is why iodine plays a very important role in your body. Iodine deficiency is one of the major reason which leads to thyroid problems. So it is important to eat the food which is rich in iodine to maintain the level of iodine in your body. This is what iodine can do for you; it can help to ensure the proper functioning of your thyroid glands in your body. The two types of hormones produced by the thyroid gland are:
- T3- Triiodothyronine
- T4- Thyroxine
The problem arises when the release of either of these hormones increases or decreases. The hypothalamus and pituitary gland also helps to maintain the balance of these two hormones, which eventually keeps the functioning of your body normal.
If the production of T3 and T4 is high in your body, your body will lose weight and you will experience diarrhea and a very fast heartbeat. On the other hand, if T3 and T4 are low in your body, your body will gain weight and you will experience constipation and slow heartbeat.
Symptoms of hyperthyroidism:
- Weight loss
- Hair loss
- Trembling hands
- Lack of sleep
Symptoms of hypothyroidism:
- Weight gain
- High cholesterol
- Joint pains
- Slower heart rate
- Brittle hair
Effect of high or low thyroid in your body:
- It will be very difficult for you to maintain an appropriate body weight because the thyroid gland directly affects the metabolism of your body. So you are likely to experience regular weight loss if you are suffering from hyperthyroidism and weight gain if you are suffering from hypothyroidism.
- Your thyroid gland produces hormones that ensure a regular menstrual cycle in your body. Suffering from hyperthyroidism and hypothyroidism can disturb your menstrual cycles and lower the chances of fertility.
- Low thyroid levels will make your skin, hair, and nails look dry, dull, and brittle because of the slow functioning of your skin cells.
- Fluctuating thyroid levels in your body can also cause you to be forgetful at times. You may feel like your brain is not working effectively and you may lack concentration. Thyroid is also one of the causes of depression.

Summary of Intensive and Coronary Care Units
- High quality ICUs are equipped with medical devices such as mechanical ventilators, bedside monitors, digital cardio tachometers, pacemakers, defibrillators, dialysis equipments etc.
- The biological information related to the patient from the bedside monitors can be analyzed by the concerned physician or nurse to provide better care.
- The various parameters from different ICU units can be sent to a central monitoring console for detailed analysis and care.
- A CCU (Critical or coronary) care unit is a special care units dealing with the care of patients with diseases connected with heart(such as heart attack).
- The cardio tachometers are used to count the heart rate of patients.
- The function of differentiator in analog cardio tachometer is to avoid double counting.
- The output of R-wave discriminator is applied to a level detector .The level detector produce an output voltage change only when the predetermined input voltage level is exceeded.
- Integrator averages the pulses applied to its input from the mono stable output.
- The difference between analog and digital tachometer is that the output from the mono stable is applied to a 4- in -1 generator.
- In cardio tachometers, alarm circuits are provided on bedside monitors to warn the staff on an emergency condition.
- Here the mechanical arrangement of alarm is designed in such a way that it will turn ON when heart rate is too low or too high.
- In modern central monitoring console units, the entire information of different patients from different bedside monitors are collected and displayed.
- The staff at the central monitoring console can continuously monitor the patients and the number of staffs at the bedside monitors can be reduced.
