It should not however, be used as a replacement for the gonioscopy examination but rather be used as a means of refuting or confirming the results of a gonioscopy examination. [3] The Van Herick's technique has become the most commonly used qualitative method of assessing the size of the anterior chamber angle (ACA).
In ophthalmology, gonioscopy is a routine procedure that measures the angle between the iris and the cornea (the iridocorneal angle), using a goniolens (also known as a gonioscope) together with a slit lamp or operating microscope. [1] [2] Its use is important in diagnosing and monitoring various eye conditions associated with glaucoma.
The Heidelberg Retinal Tomography is a diagnostic procedure used in ophthalmology.The Heidelberg Retina Tomograph (HRT) is an ophthalmological confocal point scanning laser ophthalmoscope [1] for examining the cornea and certain areas of the retina using different diagnostic modules (HRT retina, HRT cornea, HRT glaucoma).
It is often recommended that children should have their first eye exam at six months old, or earlier if a parent suspects something is wrong with the eyes. Across the world, screening programs are important for identifying children who have a need for spectacles but either do not wear any or have the wrong prescription. [14]

Two lines: If the patient sees two lines, this means that there is no suppression of either eye. Disappearing line: The patient may report that they see one line, then the lines switch and they can only see the other line. This is the case in an alternating deviation, where there is always one eye suppressing, however the fixing eye is switching.
Iris Gonioscopy of the anterior chamber angle. Schwalbe's line is the anatomical line found on the interior surface of the eye's cornea, and delineates the outer limit of the corneal endothelium layer. Specifically, it represents the termination of Descemet's membrane. [1] In many cases it can be seen via gonioscopy. [2]
In adults, the administration of the lymphangiogenic growth factor VEGFC enlarged the Schlemm's canal, which was associated with a reduction in intraocular pressure. [ 1 ] In the combined absence of angiopoietin 1 and angiopoietin 2 , Schlemm's canal and episcleral lymphatic vasculature completely failed to develop.
