What is the normal range for NCT intraocular pressure?

1. The normal range for NCT intraocular pressure (IOP) is 10mmHg to 21mmHg. Values outside this range may indicate ocular abnormalities and prompt medical attention is recommended.

2. Intraocular pressure is the pressure that results from the interaction between the contents of the eye and its walls. The primary purpose of IOP examination is to determine if the pressure is within the normal range and to assist doctors in diagnosing conditions such as glaucoma and retinal detachment. NCT is a method for detecting intraocular pressure, with a normal reference range of 10mmHg to 21mmHg. Values outside this range suggest abnormal IOP.

3. IOP higher than normal can be caused by factors such as corneal thickness, eyelash obstruction, or may be associated with glaucoma. IOP lower than normal can be caused by ocular atrophy, congenital ocular hypoplasia, retinal detachment, etc. Early examination is recommended to identify the cause and provide timely treatment.

4. During the examination, it is important to actively cooperate and remain relaxed throughout the process. Follow the doctor's instructions, including widening your eyes and remaining stationary. Inform the doctor immediately if you feel any discomfort.
