Methods of examination of glaucoma

Perimetry: 

Perimetry is the way toward graphing or recording the visual field. Visual field is characterized as an island of vision encompassed via ocean of obscurity. The visual field stretches out to 60 degrees nasally, 50 degrees superiorly, 90 degrees transiently and 70 degrees poorly.

Methods of examination glaucoma

Gonioscopy: 

It's a procedure of analyzing the perspective of a foremost chamber point. Foremost chamber point is not noticeable through the cornea because of aggregate corneal reflection. Gonioscope disposes of the aggregate interior reflection and perspectives the point structure.

Classification of glaucoma

Glaucoma is arranged into essential glaucoma and auxiliary glaucoma. Essential glaucoma is additionally characterized into essential open edge glaucoma and essential conclusion glaucoma. Open edge glaucoma is brought on because of expanded resistance in the trabecular meshwork. Edge conclusion glaucoma is brought about because of blockage of watery funniness surge because of mechanical conclusion of front chamber edge by the fringe iris.

Angle Structure

The range in the front chamber where the cornea and Iris joins is called as point. It's made of a few structures and aides in the waste of fluid diversion. The watery funniness is water like fluid that fills the space amongst cornea and iris in the front chamber. It's framed in the ciliary body, courses through the pupillary space into the front chamber and exists out of the eye through the edge structure. It offers sustenance to cornea and crystalline focal point. Nearness of watery amusingness in foremost chamber offers shape to the front segment of the eye. The creation and seepage of watery liquid decides the eyes intra visual pressure(IOP).

Glaucoma

Glaucoma is an ailment in which intra visual weight is raised which make harm visual field and optic circle. At the point when eye weight expands it obstruct the trabecular meshwork and edge structure winds up noticeably shut where fluid diversion exists.

Measures of corneal reflex

1 mm decentration of corneal reflex =7degrees=15 crystal degrees.

2 mm decentration of corneal reflex on pupillary edge = 15 degrees = 30 crystal diopter.

4 mm decentration of corneal reflex on mid iris = 30 degrees = 60 crystal diopter.

6 mm decentration of corneal reflex on limbus = 45 degrees = 90 crystal diopter.
