Vision helps us to admire the beauties, to watch how loved ones change with age. Without it, it would be difficult to comprehend the basics of science and read your favorite books. A person receives a lot from the visual organ, but forgets that vision also requires attention, at least sometimes. You can conduct an examination of the visual organ using Goldman lenses.
What is this
Before you go through any procedure, you should learn at least a little about it and the equipment on which it will be carried out. In this article, you will learn what Goldman lenses are. This device is used to study the fundus, the angle of the anterior chamber, as well as for stereoscopic observation of them and laser coagulation of their structures.
The device consists of three mirrors, which are rotated at angles of 59, 66 and 73 degrees. This arrangement of mirrors makes it possible to simultaneously examine different areas of the eye, since the light is refracted in a special way. Based on this, we can say that Goldman lenses will help to check those corners of the eye,which cannot be investigated with other methods.
It is desirable to conduct such surveys:
- people who do extreme sports;
- to expectant mothers;
- for the elderly;
- for those with eye injuries.
What is the procedure for
Most often, the examination of the fundus with a Goldman lens is carried out in combination with other methods of ophthalmology. Only in this case, the doctor will be able to get a complete picture of eye he alth. During the examination, special drops are used that dilate the pupil. After the examination procedure, you can not drive and do work that puts strain on the eyes. When a Goldmann lens is used, the examination will be complete. The doctor, using this device, can easily diagnose the condition of the patient's retina, and this must be done before an ophthalmic operation.
The advantage of this method is the ability to examine in detail the peripheral areas of the fundus and diagnose dystrophic changes and retinal detachment at the initial stage. This is very important for eye he alth. As soon as you notice a deterioration in vision, constant goosebumps before your eyes, or if your head starts to hurt badly after straining your eyes, immediately consult a doctor. At the initial stage, many diseases can be cured.
Lens care
Goldmann lenses should be sterilized. For this, a six percent solution of hydrogen peroxide is used. The outer surface of the lenses is disinfectedchemical method. A 0.5% detergent solution is added to a 3% hydrogen peroxide solution.
Optics are cleaned with a mixture of 85% alcohol and 15% ether. Dust is removed from the surface of the lenses with a fat-free brush. Be sure to ensure that the lenses are not subjected to mechanical and thermal stress.
During operation, the lenses must be held by the frame, do not touch the optical surfaces.
Forbidden:
- Wash your lenses with alcohol.
- Rinse with water below 5°C and above 30°C.
- Store near heat.
Conclusion
Don't forget that your eyes need attention too. And let them not let you down at the moment, but they are worth examining. After all, the disease can hide somewhere inside and manifest unexpectedly.
