Description
Estimated cost for Dry Eye Syndrome Treatment at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
The main clinical uses of dry eye syndrome testing include: 1. Diagnosing the presence and severity of dry eye, 2. Monitoring the effectiveness of treatment, 3. Identifying underlying causes for targeted therapy, 4. Assessing the impact of environmental and lifestyle factors on eye health, 5. Guiding decisions about surgical interventions, especially in cases where dry eye may complicate recovery.
Normal Range
For dry eye syndrome, there isn't a specific numerical range like in blood tests. Instead, normality is determined through various diagnostic methods such as the Schirmer's test (normal: >10mm of wetting after 5 minutes), tear breakup time (TBUT) (normal: >10 seconds), and ocular surface staining (minimal or no staining).
Low Values - Possible Causes
Low values or indicators of dry eye syndrome can be caused by: 1. Decreased tear production due to aging, 2. Side effects of certain medications (antihistamines, decongestants, antidepressants), 3. Autoimmune diseases like Sjögren’s syndrome, 4. Environmental factors such as wind, smoke, or dry air, 5. Prolonged use of digital screens leading to reduced blink rate.
High Values - Possible Causes
High values or excessive tearing, which might seem contradictory but can also indicate issues related to dry eye syndrome, are often due to: 1. Reflexive overproduction of tears in response to irritation, 2. Blockage or malfunction of the meibomian glands, 3. Inflammation of the eyelids (blepharitis), 4. Allergies, 5. Eye injuries or surgeries that affect tear quality or quantity.
