Patients suspected of having glaucoma need to go to the hospital for examination, which includes intraocular pressure measurement, visual field examination, ocular structure examination, corneal thickness measurement and visual acuity examination. 1. Measurement of intraocular pressure: If the patient has glaucoma, the intraocular pressure will usually increase, which can be determined by measurement of intraocular pressure. 2. Visual field examination: Patients with glaucoma may have symptoms such as visual field defects, and the visual field examination can be used to clarify the level of the patient’s visual field. 3. Examination of ocular structures: Glaucoma patients may have abnormal ocular structures, such as atrial angle closure and atrial adhesion, etc. Patients can evaluate the morphology of the atrial angle and other ocular structures through OCT and atrial anguloscopy. 4. Corneal Thickness Measurement: Corneal thickness affects intraocular pressure (IOP), so patients need to undergo corneal thickness testing to correct IOP. 5. Visual acuity testing: Patients may also undergo visual acuity testing to determine if there is any reduction in vision. It is recommended that patients with suspected glaucoma consult a doctor for a systematic examination to assess their condition and treat them as directed by the doctor.
