Diascleral transillumination or diaphanoscopy is a method of examining the eyeball that allows you to see the internal structures of the eye through the pupil. This method is used to diagnose various eye diseases such as cataracts, glaucoma, retinal detachment and others.
To carry out diascleral transillumination, a special device is used - a diaphanoscope. It consists of a lamp that illuminates the pupil and a mirror that reflects light onto the eyeball. An ophthalmologist conducts an examination by looking through the eyepiece of a diaphanoscope at the patient's pupil. If there are any changes in the eye, they will be visible on the diaphanoscope screen in the form of dark or light spots.
Diascleral transillumination has a number of advantages over other methods for diagnosing eye diseases. Firstly, it allows you to quickly and accurately determine the presence of pathology in the eye. Secondly, diaphanoscopy can be performed on an outpatient basis, which allows you to quickly obtain research results. Thirdly, this method is painless and non-invasive, which makes it more preferable for patients.
However, like any other diagnostic method, diascleral transillumination cannot always give an accurate result. Therefore, if a doctor prescribes diaphanoscopy, it is necessary to follow his recommendations and fulfill all the necessary conditions to obtain accurate results. In addition, diascleral transillumination may be contraindicated in some eye diseases, so you should consult an ophthalmologist before performing the procedure.
