There is growing interest by researchers worldwide in acupuncture for the eyes. Eye conditions are routinely treated with acupuncture in Chinese hospitals. Below are summaries of some recently published papers. You will not find research on every possible eye complaint, so do not be disappointed if yours is not there. You are always welcome to give me a call and discuss things.
Do take your eye health seriously. Our eyes are more challenged in the modern world, by things like long hours of screen use, or air conditioning in the workplace. See an optician for an eye examination at least every two years, even if you don’t wear glasses. It sometimes detects other underlying health problems.
With some conditions such as dry eye, recurrent conjunctivitis and blepharitis, there is much important lifestyle and self-care advice that I will suggest to you. It is important that you follow these recommendations if the treatment is to have maximum impact.
Researchers in the Department of Ophthalmology, University Hospital Dresden, Germany looking at acupuncture and glaucoma, have found that blood flow to the eyes can be improved by giving acupuncture to patients with primary open-angle glaucoma. Disturbances in ocular blood flow have been coming under scrutiny as a cause of visual field damage in glaucoma patients.
In the randomised study, 56 patients aged 32 to 69, were assigned to receive either a single acupuncture treatment using acupuncture points traditionally used to benefit eye health, or to a single treatment using points which are not specific to eye health. Ocular blood flow parameters were measured before treatment, and again ten minutes afterwards. Pulsatile ocular blood flow was seen to increase significantly after only the eye-specific acupuncture treatment.

Investigators at the Singapore Eye Research Institute have found that acupuncture can help dry eyes by providing benefits in addition to those provided by artificial tears. A total of 150 patients aged 40 to 85, were randomly allocated to receive either artificial tears alone (Systane Ultra four times per day), artificial tears plus eight acupuncture sessions (delivered twice a week), or artificial tears plus a Chinese herbal supplement traditionally used for dry eyes. Treatment took place over a one month period.
Compared with the group using artificial tears alone, the acupuncture group reported lower symptom scores, and also reduced conjunctival redness. Inflammatory cytokine levels in tear fluid were significantly reduced following acupuncture. The herbal supplement did not significantly alter symptom scores. No adverse effects of acupuncture were noted.
The researchers conclude that treatment involving predominantly eye drops usually provides only temporary symptomatic relief. This study suggests that 30% of people with dry eye may not actually obtain relief from drops, so alternative treatments should be explored. For mild to moderate dry eye, acupuncture can be considered, provided that there is access to suitably trained and accredited professionals.

Acupuncture has been found to offer objectively measurable improvements in tear film quantity in patients with certain types of dry eye. A total of 108 such patients were randomised to receive either acupuncture or artificial tears. Both groups were divided into three subgroups based on their type of dry eye: lipid tear deficiency, Sjogren dry eye and non-Sjogren dry eye. Acupuncture was given three times per week for four weeks. Artificial tears were permitted four times per day in both eyes, for four weeks.
After four weeks of treatment, compared to baseline measurements and control groups, tear film quantity had increased significantly in the acupuncture group for lipid tear deficiency and non-Sjogren dry eye, but not for the Sjogren dry eye group. Where the latter group is concerned, the authors speculate that the treatment period may have been too short, and that given the chronic degeneration of specialised cells which occurs in Sjogrens, a more complex approach to treatment may be necessary.

A pilot study undertaken by researchers at John Hopkins University in the USA, suggests that acupuncture may offer significant and measurable improvements in residual visual function for patients with the degenerative eye disease retinitis pigmentosa (RP). RP is an inherited eye condition in which the cells of the retina gradually stop working. Twelve adult patients with RP were given ten 30 minute acupuncture sessions over a two week period.
After treatment, six of the twelve showed significant improvements in visual function. Three of nine subjects given a full-field stimulus threshold test, had a 13- to 53-fold improvement in both eyes at one week after acupuncture, maintained for at least 10 to 12 months. Acupuncture was well-tolerated by all, without adverse events or visual loss. The researchers conclude that acupuncture entails minimal risk, if administered by a well-trained acupuncturist and may have significant, measurable benefits on residual visual function in patients with retinitis pigmentosa, in particular scotopic sensitivity, which had not previously been studied. These preliminary findings support the need for future controlled studies of potential mechanisms.
