Did you know How is glaucoma diagnosed? Wonder about that? I guess only eye doctor can answer that. You can found many article about this. But i share you 2 way how glaucoma can be diagnosed.
An eye doctor (ophthalmologist) can usually detect those individuals who are at risk for glaucoma (because of, for example, a narrow filtering angle or increased intraocular pressure) before nerve damage occurs. The doctor also can diagnose patients who already have glaucoma by observing their nerve damage or visual field loss. The following tests, all of which are painless, may be part of this evaluation.
Tonometry determines the pressure in the eye by measuring the tone or firmness of its surface. Several types of tonometers are available for this test, the most common being the applanation tonometer. After the eye has been numbed with anesthetic eye drops, the tonometer’s sensor is placed against the front surface of the eye. The firmer the tone of the surface of the eye, the higher the pressure reading.
Pachymetry is a relatively new test being used for the management of glaucoma. Pachymetry determines the thickness of the cornea. After the eye has been numbed with anesthetic eye drops, the pachymeter tip is touched lightly to the front surface of the eye (cornea). Recent studies have shown that central corneal thickness can affect the measurement of intraocular pressure. Thicker corneas may give falsely high eye pressure readings and thinner corneas may give falsely low pressure readings. Furthermore, thin corneas may be an additional risk factor for glaucoma. treatment.
I believe you can will be more careful in future. So, be careful.
Eyeman - I hate glaucoma..
What are the symptoms of Cataract ? Did you know any single of symptoms of cataracts??
Although cataracts develop without pain or discomfort, there are some indications that a cataract may be forming. These include:-
- Blurred or hazy vision.
- Sensitivity to sunlight (glare) or the feeling of having a film over the eyes.
- Poor night vision.
- Appearance of spots in front of the eyes.
- Loss of ability to see brightness of colors.
- Discolored (white) pupil.
- Difficulty with daily activities such as driving and reading.
- Temporary improvement in near vision may also indicate the formation of a cataract.
- Double vision or ghost images. (really??)
I believe not many people know about this symptoms. HUhu..
Eyeman – Sometimes i have blurred and hazy vision. I hope its not a first symptoms i have..
Did you know How we can treat Cataracts?? I believe not many people know about that.
Ehm..There is no non-surgical treatment for a cataract. Preventive measures include wearing good ultraviolet (UV) blocking sunglasses as a protection from the sun. Anti-oxidant vitamins may retard cataract changes. There are no medications, dietary supplements, exercises or optical devices to cure cataracts. If symptoms from a cataract are mild, prescription glasses may be sufficient to function more comfortably. Surgery is the only way a cataract can be removed and cured. This treatment involves removing the cloudy lens and replacing it with a substitute lens.
Removal of Cataract There are two important ways to remove a cataract:
Phacoemulsification, or phaco: In this technique the doctor makes a small incision on the side of the cornea, (dome-shaped surface that covers the front of the eye). The doctor then inserts a tiny probe into the eye. This device emits ultrasound waves that soften and break up the cloudy center of the lens. Most cataract surgery today is done by this method and is done by using local anaesthesia. This is also called “out patient” or minor cataract surgery.
Extracapsular surgery: A longer incision on the side of the cornea is made to remove the hard center of the lens. The remainder of the lens is then removed by suction and replaced by an intraocular lens (IOL). An IOL is a clear, artificial lens that requires minimal care and becomes a less than permanent part of the eye and improves vision. The operation usually lasts 1 hour and is almost painless.
Can a Cataract Return?
A cataract cannot return because all or part of the lens has been removed. However, in some people who have had extracapsular surgery or phacoemulsification, the lens capsule becomes cloudy after a year. It causes the same vision problems as a cataract does. To correct this, laser capsulotomy can be performed. In laser (YAG) capsulotomy a laser (light) beam is used to make a tiny hole in the capsule to let light pass. This surgery is painless and does not require stay in the hospital.
Eyeman : I never know about this treatment. But i guess, its useful to know..
Did you know how cost of cataract surgery? See this list..
Procedures Costs
First consultation$ 80
Follow up consultation$ 50
Pre-refractive surgery assessment (e.g. LASIK and ICL implants)$ 180 – $ 250
Pre-operative assessment (e.g. cataract surgery and pterygium surgery)$ 150 – $ 200
Bilateral LASIK (both eyes operated on the same day)$ 3000
Bilateral EpiLASIK$ 3000
Implantable Contact Lens (ICL) surgery (per eye)$ 2800 – $ 3300
Cataract surgery (per eye)$ 2500 – $ 2800
Conductive Keratoplasty (per eye)$ 1500
Presbyopic LASIK (per eye)$ 2800
Contact lens fitting (Soft or RGP, multifocal or single vision)$ 40 – $ 80
Subjective refraction$ 25
Subjective refraction and cyclo-refraction$ 40
Optical service$ 10
SEE? Its $2500 per eye. If 2 eyes. Its around $5000!! Its really expensive. So, better you take care about your eyes. If not, you will use your money like this.
Eyeman – I hope my eye wil always fine.
