How does glaucoma have visual field examination?

summary

The progress of glaucoma was monitored by visual field examination. Whether the anti glaucoma treatment is effective or not depends not only on the intraocular pressure, but also on whether the optic disc damage and visual field defect continue to progress. Intraocular pressure fluctuates within one day. A normal measurement of intraocular pressure does not mean that the control of intraocular pressure is satisfactory. In primary open-angle glaucoma, especially those with normal intraocular pressure glaucoma, the tolerance of optic disc to intraocular pressure is low. Even if the intraocular pressure is in the normal range, the visual function damage may continue. How can cyanotic eye conduct visual field examination? Now let me tell you something.

How does glaucoma have visual field examination?

Visual field examination technology has made great progress, especially the computer-aided visual field examination, the accuracy and reliability are significantly improved, and the examination results can be accurately recorded and saved for comparison. In patients receiving anti glaucoma treatment, the comparison of continuous visual field examination results is a sensitive indicator of the progress of the disease. The stable and unchanged visual field defect means that the treatment is effective, and the progressive deterioration of the defect is an indication of the need to strengthen the treatment.

Visual field defect was detected and nerve damage was judged. The diagnosis of glaucoma is not completely determined by intraocular pressure. Only high intraocular pressure without optic disc damage and corresponding visual field defect can be diagnosed as ocular hypertension. On the contrary, normal tension glaucoma, normal intraocular pressure, only optic disc changes and visual field defects. Therefore, visual field defect is one of the main indicators in the diagnosis of glaucoma, which is particularly important in primary open-angle glaucoma. In clinic, patients with ocular hypertension can not be treated, regular follow-up of fundus and visual field, once there is early optic disc damage and visual field changes, treatment.

Check intraocular pressure: in the early stage of glaucoma, intraocular pressure is often unstable, only a few hours a day intraocular pressure rise. Therefore, measurement of 24-hour intraocular pressure curve is helpful for diagnosis. Fundus changes: optic disc depression is one of the common signs of glaucoma. With the development of the disease, the physiological depression of the optic disc gradually expands and deepens, and finally reaches the edge, forming a typical cup-shaped depression of glaucoma.

matters needing attention

For glaucoma, it is best to use drugs first. If the intraocular pressure can not be controlled under the maximum dosage, surgical treatment can be considered. We should use low concentration of liquid medicine first, and then use high concentration of liquid medicine eye drops, and according to the effective antihypertensive time of different drugs.
