Brief summary

This project is designed as a prospective, randomized, open, controlled clinical trial. For the first time, acupuncture was applied to the treatment of dry ocular neuropathic pain. Its mechanism was discussed by comparing the efficacy between acupuncture and artificial tears.

Design outcomes

Primary

MeasureTime frameDescription
Visual Analogue ScoreThe treatment period for each enrolled subject is one monthAsk the patient to mark the corresponding position on the ruler that can represent the pain or discomfort during the onset

Secondary

MeasureTime frameDescription
TBUTThe treatment period for each enrolled subject is one monthDrop 1 drop of 0.3% sodium fluorescein eye solution into the subject's conjunctival sac, dry it with a sterile cotton swab, and ask him to blink gently to make the fluorescein sodium evenly distributed. Observe the subject from the last time with a slit lamp cobalt blue light. The time from blinking to the first dark spot on the corneal surface, record three times and take the average
SItThe treatment period for each enrolled subject is one monthFold one end of the special 5mm×35mm filter paper (Tianjin Jingming) for tears by 5mm, and gently place it on the middle and outer 1/3 of the subject's lower eyelid conjunctival sac, and the other end will droop naturally. Ask the subject to gently close their eyes for 5 minutes After measuring the length of the filter paper wetted by tears
OSDIThe treatment period for each enrolled subject is one monthOSDI consists of 12 scoring items, divided into three parts: severity of symptoms, impact of symptoms on daily life, and impact of environment on symptoms.
Density and curvature of corneal subbasal nerveThe treatment period for each enrolled subject is one monthCollect corneal subbasal nerve images, 2 images each in the upper, lower, arm, temporal and central areas. Use deep learning methods to analyze nerve density and curvature
Tear pain factor contentThe treatment period for each enrolled subject is one monthWith the aid of a slit lamp, a capillary pipette was used to draw 5 μl tears/eye at the middle and outer edges of the lower eyelid 2/3 of the tear river, and placed in a low protein adhesion EP tube (containing 5 μl 1% BSA) and stored at -80°C. ELISA analyzes the protein levels of PGE2, substance P and NGF in tear fluid.
CFS scoreThe treatment period for each enrolled subject is one monthDivide the cornea into 5 quadrants (central + nose/temporal/upper/lower), each quadrant has a staining score of 0 to 3 points, and it is specified that no staining is 0 points, and 30 spots are stained as 1 point, and there is flaky staining and fusion 3 points for filament formation, 2 points between the two, the sum of 5 quadrants is the score of the entire cornea, and the CFS score of the entire cornea is 0-15 points.
