How to Test Vision in Guangzhou Department of Ophthalmology for Women and Children
Guangzhou Women and Children's Ophthalmology Department is a hospital specialized in providing ophthalmic services for women and children. There are various ways to test vision. Vision is the ability of people to perceive and understand visual information. It is a part of eye function and an important indicator of eye health. The following will introduce how Guangzhou Women and Children's Ophthalmology Department tests vision from four aspects.
1. Vision examination
Vision examination is one of the most commonly used test methods to evaluate people's ability to recognize objects at a distance. Guangzhou Women and Children's Ophthalmology Department uses standard vision charts and projectors to check vision. During the examination, the doctor will ask the patient to look at the letters or figures on the vision chart, and then ask them to identify the contents. By measuring the smallest font size that patients can clearly recognize, doctors can determine their vision level.
In addition, Guangzhou Women and Children's Ophthalmology Department can also use other vision examination methods, such as fundus examination, visual field examination and intraocular pressure measurement. These examinations can help doctors assess the patient's eye health, and timely detect and diagnose eye diseases.
2. Color vision inspection
Color vision test is a method to test people's ability to recognize and perceive different colors. Guangzhou Women and Children's Ophthalmology Department can check color vision by using color vision test chart and test paper. During the examination, the doctor will ask the patient to recognize different color images or words, and evaluate their ability to distinguish different colors.
Color vision examination is particularly important for children and some specific groups, such as those who are color blind or weak. Through early detection and diagnosis of color vision problems, doctors can provide corresponding treatment and suggestions to help patients better adapt to daily life.
3. Eye tracking inspection
Eye tracking is a method to evaluate people's eye movement and coordination ability. Guangzhou Women and Children's Ophthalmology Department can use electronic equipment and computer programs to track eye movements. During the examination, patients need to focus on specific targets to move their eyes, and doctors will observe and record their eye movements.
Eye tracking can help doctors evaluate whether the patient's eye muscle strength and cooperation ability are normal, and whether there is eye movement disorder. For children, eye movement tracking can also be used to assess their visual development, and timely detect and intervene potential visual problems.
4. Corneal topography examination
Corneal topography is a method to evaluate corneal curvature and morphology. The corneal topography can be used for examination in Guangzhou department of gynecology and ophthalmology. During the examination, the patient needs to put his chin on the stand and aim at the target point of the examination instrument for staring. The instrument will obtain the shape and curvature data of the corneal surface by measuring the reflected light.
Through corneal topography examination, doctors can assess the patient's corneal health, and know whether there are corneal diseases or refractive errors. This helps doctors to determine the glasses or contact lens matching scheme suitable for patients, as well as the follow-up treatment plan.
