Efficacy of Acupuncture in Macular Diseases (AMAD)

¿Es Util la Acupuntura en la Degeneracion Macular? Prospective Study of Efficacy of Acupuncture in Macular Diseases

This is a single-arm study designed to assess the efficacy of acupuncture (Traditional Chinese Medicine) for chronic macular diseases of several types. All participants received acupuncture and massage and there is not a placebo group because it is not considered a good form to evaluate in Chinese Medicine due to, acupuncturing being a procedure is not as blind as is desired. As a control of the results in this trial, the outcomes could be contrasted against those reported in known medical publications and against expectations of the progress of the damage without treatment.

Background. WHO has included retinal diseases between conditions treatable by acupuncture and Traditional Chinese Medicine (TCM) has been used for retinal diseases in hospitals of China and in other parts of the world many years ago. Acupuncture and periocular massage act stimulating the vital energy to restore the normal function of the body. Currently, most common treatments in Western Medicine, anti-VEGF, only are indicated for less than 10 percent of cases, which are the wet form or neovascular of AMD (NV-AMD) and they have restrictions for use, additionally, their cost and requirements are limiting for populations in all countries. Objectives. The primary purpose of this study is to confirm the objective response among subjects with macular diseases treated with acupuncture and massage. The results of conventional treatment are published in similar trials and some of our patients have had intraocular injections previously. It is important to feature the affordability of this therapy for low-income populations that do not have specialists or facilities nearby or for many governments that complain about the huge burden of the treatment of there diseases. In Colombia, the average cost of each intraocular injection by the time of this trial was about US 3.500 and it can be repeated every month, it requires a retina specialist and a surgical room, that is out of reach for many people in the country. We did not calculate the costs of our treatment because the research team did voluntary labor, and the devices are at a very low cost, about US 0.50 in each session. Acupuncture treatment does not require special facilities as surgical rooms required in treatments with intraocular injections. The participants were not paid, they came from different economic conditions, some better, others from poorest neighborhoods or some from the rural areas. This study includes 3 phases: Selection, Treatment, and Follow-up phases. The selection phase included confirmed diagnosis by clinical register and OCT, Ophthalmologic assessment, and consent of the patient. Macular diseases. In this trial, some patients had NV AMD in one or both eyes, dry AMD, myopic maculopathy or Stargardt disease. For TCM it is possible to treat all as damage of similar category. Why no control group. There was no control group due to ethical reasons, leave the impairment without treatment in these mostly very sad persons. The second reason is the well-known difficulty to mask a procedure like acupuncture. another third reason is the possibility to contrast the results of this trial with those of similar studies conducted in eyes with conventional treatment. In the phase of treatment, Patients received a session of acupuncture according to a standard protocol of points, and a periocular massage that was taught to the patient to be self-performed daily. The acupuncture sessions were scheduled every week initially, the evaluation of response was realized every 2 months by ophthalmologic exam and was asked to participants an optical coherence tomography (OCT) that would be realized every 6 months. Depending on the results of ophthalmologic assessment the sessions were extended gradually to every 2, 3, 5 until 13 weeks. Although tomographic assessments had been scheduled every 6 months, only a few of the participants accomplish with that due to economic limitations. Treatment continued until 24 months All patients in the follow-up phase of this trial were monitored according to the Safety Follow-up protocol and the defined procedures and evaluations. The final results were collected and analyzed.

Acupuncture and massage Therapy of Traditional Chinese Medicine (acupuncture and Massage) for 24 months .

Treatment consists in to put needles on specific points of skin one day each week initially, then with longer spaces of time according to improvement.A total of 11 Chinese needles stainless steel, 25 x 40 were used by manual insertion and left for 12-15 minutes. Periocular massage is taught and is practiced daily by the patient him or herself.

The primary objective is to assess if acupuncture treatment is linked to a change in visual acuity (VA). VA was obtained by an ophthalmologic assessment at baseline and every two months until month 24. VA measurements were taken with the patient in a sitting position using a Snellen chart at a testing distance of 6 meters. The scale in Snellen is given in fractional numbers corresponding 20/20 to a normal vision at 20 ft or 6 meters. According to the World Health Organization, the normal vision is to 20/25, severe impairment corresponds to VA worse than 20/200 or legal blindness. Each fraction corresponds to a determined line of the chart in which all letters are correctly identified and the variation or gain is appreciated by the lines gained or lost by each eye. Improvement means a fraction better than initial, stable is no change in VA and lost is the VA worst than those of baseline.

Eyes With Change From Baseline to the End of the Study in Distance Vision According to Categories CIE 10 Based on Lines Seen on the Snellen Chart.

Change in Visual Acuity was Measured by the Numbers of Lines seen on the Snellen Chart from baseline to the end of the trial. The measure was obtained by an ophthalmologic assessment on both eyes at the beginning of the study and every two months until month 24 using the best correction. VA measurements (lines in which all letters are correctly identified) were performed with the patient in a sitting position using a Snellen chart at a testing distance of 6 meters and the variation is appreciated by the lines gained or lost by each eye. The measure in Snellen is given in fractional numbers. Each fraction corresponds to a determined line of the chart corresponding VA 20/20 or 6/6 to a normal vision at 20 ft or 6 meters. The range of normal vision according to the WHO is to 20/25 ft or 6/10m, Mild means VA worse than 6/12, Moderate means VA worse than 6/18, Severe means VA worse than 6/60 that is "legal blindness". Blindness is considered VA worse than 3/60.

Change From Baseline in the Number of Letters Seen on the Early Treatment Diabetic Retinopathy Study (ETDRS) Eye Chart

The ETDRS scale of letters is commonly used to report outcomes in AMD, for this reason, this score was chosen to compare outcomes with similar studies. Accepted tables for conversion from Snellen to ETDRS were used. 85 letters are equivalent to 20/20 and 0 letters correspond to 20/200. It can be meaningful to analyze the results in this trial in the context of similar trials using anti-VEGF, or reporting a visual loss in those cases that are not treatable.

Number of Eyes That Improved VA From Baseline to End of the Study in Participants With Different Forms of Macular Disease Treated With Acupuncture.

"Improved" was defined as cases that gained in visual acuity (Note: no minimum of letters was defined). "Stable" was defined as visual acuity did not change in the sense of not losing or gaining in the final identification of the optotypes. "Lost" was defined as patients who had a worse vision at the end than at the beginning (e.g., lost visual acuity because the disease continued its course and the treatment was not effective.)

Percentage of Participants Who Experienced Changes in Vision (Less Opacity, Less Distortion of Lines, Reduction of the Central Shadow)

At study entry, major complaints of patients were collected by survey. Participants also completed a survey at the middle and at the end of the trial. This data is the percentage of participants that reported changes to the main visual complaints that they considered significant in their lives compared with the baseline.

To report this measure the adverse events or risks had to be observed carefully and registered in order to care for the safety and to accomplish regulations of any treatment or medical intervention. For this procedure, the usual risks are some adverse events as moderate to severe pain, bleeding of more than a drop, ecchymosis bigger than 5 millimeters. Deaths and other serious events related or not with the therapeutic procedure, had to be reported.
