Colour blindness is an eye condition that is referred to as the inability to perceive certain colours. Most people who are colour-blind have inherited the condition from their parents.

Those who acquire colour blindness obtain it due to certain diseases and eye related infections such as glaucoma, macular degeneration, cataract, eye injuries and diabetic retinopathy. Colour blindness occurs when one of the cone cells at the macula fails to function. Due to its development a person is unable to perceive colours such as green, red, blue or yellow. Eye doctors prescribe corrective lenses in order to manage it since there is no proper treatment.

Test for color blindness is important since most Australian institutions require their employees to take it. Professions that require this test are such as the police department and airway lines for the pilots. There exists several colour blindness tests that people can engage to test whether they are colour-blind or not. Ishihara plates colour blindness test is the most commonly used test. It involves coloured circles that show a number and only individuals who are not colour blind can see it. This type of test can only let you know the type of colour blindness you have but not its severity.

The Farnsworth dichotomous key is a test for colour blindness that is also referred to as the Farnsworth D-15 test. It involves twenty two mixed coloured plates that are in four batches and an individual is required to arrange the rows in a correct order. Individuals get to know the type of colour blindness they have depending on where their biggest error is. Individuals who make lots of misplacements are said to have a severe condition.

Test for color blindness may also involve the following: the colour arrangement test and the RGB anomaloscope. Individuals can also find many colour blind tests online.

Eye Disorders cause eye discomfort, poor vision and others may lead to total blindness. Such disorders include: Age related macular degeneration-it is the deterioration of the macula which is the centre of the retina that allows the eye to view fine details in an object. This type of disorder leads to lose of the central and sharp vision. The disorder is classified into two categories i.e. the wet form which is described by blood and fluid leakage; this occurs when abnormal blood vessels that are located behind the retina grow below the macula and the dry form which develops when the macula thins during the aging process.

Cataracts-it is an eye disorder that causes clouding on the eye lens making it not to transmit light properly. The disorder is known to be a silent killer of vision, since it develops slowly and can lead to total blindness if not treated early. Conjunctivitis also referred to as the pink eye-is the swelling of the conjunctiva blood vessels. The conjunctiva is a thin membrane that covers the inner surface of the eye and eyelids. This condition is characterized into three types depending on its cause and they include bacterial, viral and allergic conjunctivitis.

Diabetic retinopathy-it is among the Eye Disorders that affect the retina. This condition damages the retina’s blood vessels and the light sensitive tissue located at the back of the eye which promotes good vision. It is a common eye problem in diabetic patients and also the leading cause of blindness. Strabismus-also referred to as a crossed eye is an eye problem that involves the position imbalance of both eyes. The condition causes either esotropia that is crossing in of the eyes or exotropia that is turning out of the eyes. Other common Eye Disorders include: glaucoma, amblyopia, refractive errors and uveitis.

Fred Hollows was a popular ophthalmologist from Sydney; he was born in the year 1929. He studied medicine and later specialized in ophthalmology and via this knowledge he restored the sight of many Australian citizens. He fought for the reduction of costs in the eye care and treatment; he also improved the health of indigenous Australians. The Fred Hollows foundation was established in 1992 just a few months before his death. The main aim of the foundation was to continue with the work Fred started in Australia and other countries like Eritrea and Vietnam which is to prevent blindness and to improve eye health.

Some of the foundation’s achievements include: establishment of IOL laboratory in Asmara and the introduction of modern cataracts surgery in Eritrea. They have also ensured that eye health care is prioritized in countries such as Eritrea. By manufacturing less expensive lens, the Foundation has increased its local and export sales. The Fred Hollows IOL laboratory have continued to provide eye care services at a low cost all over the world and has now become a self -sponsored centre. The foundation has managed to reduce the cost of cataracts surgery in various developing countries.

In the recent years Fred Hollows foundation has promoted and supported eye health care training in eye care services, program management, maintenance of equipment’s, small incision surgery of diseases like cataracts surgery and training of ophthalmic nurses. Through the self-sponsored workshops the foundation has been able to complete the national five year strategic plan for eye care. The plan consists of the framework that entails the Australian eye care needs and methods of supporting the health system of the national public.
Fred Hollows foundation has also been involved in supporting eye health care centres around the world by funding and also donating equipment’s. The foundation has been able to maintain its aim and also achieve its goals.

Conjunctivitis or pink eye is an eye disease that causes an inflammation on the eyes conjunctiva. It is a highly contagious infection that is common in children. It manifest itself through the following signs and symptoms: photophobia, crusts on the eyelids, blurred vision, excess tear production, eye redness and production a yellow-green discharge. It is classified into three forms depending on the main cause, the forms include: viral conjunctivitis, bacterial conjunctivitis and allergic conjunctivitis.

Conjunctivitis Treatment is differs among the three types of conjunctivitis, since their sources of infection also differs. In order to avoid contamination between infected people; normal people are urged to avoid sharing items such as towels. Moreover, people are urged to wash their hands after touching their eyes. Conjunctivitis can also be treated at home by using over the counter lubricant eye drops to reduce discomfort. One may clean the discharge present on the eyelids via use of a soaked cotton wool. To avoid reinfection, patients using contact lenses should discard them if they had been contaminated.

Antibiotics such as eye drops and eye ointments are known to be the most effective form of Conjunctivitis Treatment. Viral conjunctivitis can be treated via use of artificial cold packs in order to get rid of the swelling. If the condition is severe for example conjunctivitis caused by herpes simplex virus doctors are known to prescribe antiviral medications. In bacterial conjunctivitis, topical antibiotics such as eye drops and eye ointments are used. Inflammation and eye dryness is relieved via use of artificial tears and cold compresses.

Allergic conjunctivitis develops when an individual comes into contact with an allergen or irritant. This condition can either be seasonal, perennial, giant papillary or contact dermato-conjunctivitis. Treatment is through use of allergy medications, including antihistamines and mast stabilizers like steroids and decongestants. These two forms of medication act by reducing the inflammation. But the best Conjunctivitis Treatment for allergies is to avoid the irritant.

Colour blindness is one of the commonest disorders that have affected most males in Australia. Colour blindness is defined as the inability of a person to differentiate given colours. Scientifically, this disorder is known to be genetic; nonetheless, the condition may prevail due to eye damages/ injuries that are mainly caused by accidents or exposure to poisonous chemicals.

Thus, it is important for any Australian to conduct a thorough Colour Blind Test in the event that he or she develops difficulties on colour recognition. Colour perception test can be carried out for all age types. The nature of test to be carried out will depend on the severity of the colour blindness condition. The commonest tests used in Australia include: Ishihara test; F-M 100 Hue Test; Colour Arrangement Test; and RGB Anomaloscope test. Of the four tests, the Ishihara test is the commonest one.

The Ishihara Test is defined by a group of coloured plates; the plates are known as Ishihara plates. The plates are incorporated with dotted circles. The dotted circles are in randomized size and colour. The circles are composed of dotted numbers of different colours; the numbers are normally visible to people with normal eyesight. On the other hand, the numbers are invisible to people with impaired vision. Moreover, the dotted numbers are also invisible to people with red-green colour blindness. The full Ishihara test is composed of a maximum of t hirty eight Ishihara plates; however, most tests will show results after a few plates.

The next commonest Colour Blind Test is the colour arrangement test. This test is simple and it can be conducted at home with the help of a person with normal colour recognition abilities. A person with colour blindness will be required to obtain the various types of colours and arrange them correctly. People with colour blindness will arrange the colours incorrectly while people with normal colour recognition abilities will arrange the colours correctly.

Sydney medical care has grown significantly in the recent past. The city is defined by its recognizable technological developments. These developments have been witnessed in the medical sector. The Australian government has ensured that the city’s potential has been widely utilized.

Any Hospital in Sydney will offer you the best services. Such a hospital can be a general medical hospital or a specialized hospital such as the Sydney Eye hospital. The individual hospitals are recognized nationally as well as internationally.

Lastly, each Hospital in Sydney has been contributing greatly towards the production of new medical practitioners in the various fields of medicine. For instance, Sydney Eye hospital has a running educational facility that is aimed at training eye specialists.

Colour Blindness is a vision problem that is described as the inability to distinguish various colours such red, green, blue and a mix of the above colours. This condition develops in the eye cells that are located on the retina that is the rod and cone cells. The rod cells are sensitive to light and they help an individual to see well at night in shades of black, white or grey. These types of cells do not see different colours like the cone cells. Cone cells on the hand react to bright light and assist in the viewing of detail in objects.

Most colour blind individuals inherit the condition from their parents due to a defect on the gene for colour at the X chromosome. Individuals who develop Colour Blindness later in life obtain it due to eye injury or diseases that affect the optic nerve or the retina. Such eye diseases include: glaucoma, diabetic retinopathy, cataracts and macular degeneration.

A person with this vision problem exhibits the following signs and symptoms. They strain to distinguish colours, are unable to see various shades of the same colour and obtain rapid eye movement.
There are different types of Colour Blindness cases and they include the following: protanopia which arises due to the absence of red retinal photoreceptors; people with this condition are unable to identify red colour since red appears to them as dark colour. Deuteranopia-is a condition that is characterized as the inability to differentiate between red and green. Tritanopia that is the blue-yellow Colour Blindness is a rare condition; individuals who obtain it are unable to view the blue colour. This is due to the lack of blue retinal receptors.

Colour Blindness cannot be treated hence eye doctors manage it by prescribing their patients with coloured spectacle lenses or single red tinted contact lenses.

There are different types of eye doctors who differ in their line of specialization. Sydney Eye Hospital Doctors include; optometrists, opticians and ophthalmologists. An optometrist is a doctor who offers eye health care services. They obtain a two year technical degree and get a license that authorizes them to examine, make a diagnosis, treat and also manage eye problems.

They work together with ophthalmologists and optometrists in order to make a diagnosis and decide on the form of treatment. They also offer patients the care needed before surgeries, procedures and eye examination. They are certified to prescribe glasses, contact lenses and to treat vision diseases via non-surgical procedures.

The next important sets of Sydney Eye Hospital Doctors are the ophthalmologists. They are eye doctors who have specialized in the field of ophthalmology. Their training is lengthy since it can take up to twelve years which includes the years of specialization. They are fully certified to offer the entire eye health care services that involve both medical and surgical services. These services include; prescription of contact lenses or eye glasses, diagnoses of eye disorders, eye examinations, treating eye diseases, removing ocular tumours and surgical procedures. Ophthalmologists specialize in specific areas such as paediatric ophthalmology, neuro-ophthalmology or plastic surgery.

Opticians are also among the best Sydney Eye Hospital Doctors who work as a team with ophthalmologists and optometrists in order to provide eye care services. They assist in the evaluation and interpretation of prescriptions in order to provide fitting eye glasses. They also repair, adjust and replace eyewear such as spectacles, artificial eyes, contact lenses, frames and low vision aids. Opticians are responsible for the ordering of eye products.

Sydney Eye Hospital Doctors are the ideal eye health care specialists to consult since they work as a team. This enables them to obtain a proper diagnosis that will enable them to come up with an effective treatment regimen.

The retina is a curved layer that is located at the back of the eye; it is surrounded by light sensitive cells known as the rods and cones. Rod cells function is to respond to dim light while the function of cone cells is to distinguish colours such as red, green and blue. Retina Problems can lead to partial or total blindness. They are mainly caused by various diseases such as diabetes and macular degeneration.

Here are some of the common Retina Problems: Retinal detachment-it is a condition whereby the retina is pulled from its specific position.

That is, the retina is separated from the nerve tissues and blood vessels that are below it. This separation leads to leakage of fluids that entre into the inner portion of the eye hence causing loss of vision.
Retinal detachment can also arise if some of the retinal areas are torn; these torn areas are known as retinal tears. Patients with this disease exhibit the following symptoms: spots that float in the vision, flashes of light and retinal tears. The disorder is treated by the use of laser procedure and its occurrence can be prevented if the retinal tears are treated before they become severe.

Diabetic retinopathy-it is among the Retina Problems that damages the retina’s blood vessels. It leads to break down of blood vessels hence leakage of fluids which leads to poor vision. If the retina has scars from healing blood vessels, the retina can be pulled away from its location which leads to a retinal tear. This condition has been termed as a leading cause of vision loss and total blindness.

Diabetic patients are at a higher risk of obtaining diabetic retinopathy. In order to prevent developing this eye problem, diabetic patient should control their blood sugar levels. Retinoblastoma-it is a retina problem that is described as an eye cancer that develops at the retina. It mainly occurs in children and its warning symptom is whiteness on the pupil.

An ophthalmologist is an eye doctor who has specialized in the field of ophthalmology. Ophthalmologists are licensed medical or osteopathy doctors who upgrade their training in order to diagnose the various eye disorders that are known to affect the entire visual system. Some of the procedures they perform include: eye surgery, screening, treating eye diseases, eye examination and prescription of eye glasses and contact lenses.

The process of becoming an ophthalmologist is known to be lengthy, since it involves twelve years of training and can be longer if an individual pursues various subspecialties. The subspecialties involve specialization in specific eye care areas such as retinal diseases and paediatric ophthalmology. People interested in pursuing a course in ophthalmology are required to attain a four year training in college, a degree in medicine which involves a four year training in a medical school, one year for clinical training and a three year hospital based training in ophthalmology.

Trainees who complete their training are required to be board certified, that is to obtain a license that authorizes them to operate as ophthalmologists. Certification differs in various states hence it’s highly recommended that one should be well informed on the current details. An ophthalmologist job tasks involves managing both medical and psychological ophthalmic conditions. They also assess and examine the visual system of the patients in order to make a diagnosis.

They carry out surgical procedures like laser surgery and small incision surgery in order to treat eye diseases such as cataracts and glaucoma.
An ophthalmologist is also authorized to carry out tissue biopsy and use various therapeutic procedures like the laser therapy. He or she also gets to manage disorders like diabetes, genetic disorders or neurological disorders that affect the vision of a person. In addition, ophthalmologists work together as a team with other specialists, including ENT surgeons and neurologists in order to make informed decision on various medical conditions.
