Plain English Summary

Background and study aims
Eye styes are a lump on the eyelid that have clinical similarity to the inflammation of sebaceous glands. Based on clinical observations made at Government Ayurveda College Hospital, Thiruvananthapuram, the recurrence of the disease is defined as the re-appearance of the abscess in the same eye within a period of two months, even after incision and drainage. As per Ayurveda philosophy, the involvement of blood impurity causes eye styes to recur and leech therapy can be used to treat blood vitiation. Hence incision and drainage and leech therapy were incorporated to manage recurrent eye styes.

This study aimed to find the combined effectiveness of incision and drainage followed by leech therapy in managing recurrence of eye styes.

Who can participate?
Patients aged between 10 and 50 years with recurrence of eye styes in the same eye within a two month period even after surgical treatment

What does the study involve?
After obtaining consent, patients were randomly allocated to either the study group or the control group. In the study group, surgical intervention (incision and drainage) was followed by leech therapy. In the control group, incision and drainage were performed. The follow up was arranged on 15th day, 45th day, 75th day, and 105th day after treatment.

What are the possible benefits and risks of participating?
No side effects were noticed throughout the study period.

Where is the study run from?
Department of Shalakyatantra, Govt. Ayurveda College TrivandrumGovernment Ayurveda College Hospital (India).

When is the study starting and how long is it expected to run for?

Scientific titleComparing surgical treatment alone vs surgical treatment followed by bloodletting by medicinal leeches in the treatment of recurrent eye styes: a randomised controlled trial.
Study hypothesisA study on the combined effectiveness of surgical intervention followed by blood letting by medicinal leeches in recurrent eye styes. Blood letting by medicinal leeches will be user friendly and will not negatively effect management of the disease state
Ethics approval(s)Approved 22/04/2013, Institutional Ethical Committee of the Government Ayurveda College Trivandrum (Kerala, India; +91 (0)471 2460190), ref: IEC.0422.12/2013
ConditionEye stye
InterventionPatients diagnosed as having recurrent eye styes were selected from the outpatient department and admitted to the inpatient department of Shalakyatantra at the trial site. After obtaining consent, patients were randomly allocated into either the study group or control group using a block randomization method. In study group patients were treated with a surgical intervention, incision and draining, followed by leech therapy. The control group were treated with incision and draining only.

Study group-treatment protocol
Pre-operative procedure
1. Administering of herbal ghee (dose according to age) for one day, the first day. Two times along with porridge.
2. The inducing of mild sweating with leaves over the eye stye was advised for one day, the first day. Bathing in hot water was also advised.
3. The herbal powder, avipathi choornam (dose according to the age) was administered along with hot milk as a part of purgative therapy for one day, the second day

Procedure
1. Incision at pus point by surgical blade (No.12) and evacuation.

Post-operative procedure
1. Rub the wound with rock salt and honey
2. Wash the wound with lukewarm distilled water
3. Bandaging:
3.1. Eye bandage with honey and herbal ghee
3.2. 3rd day, re-bandage after pouring medicated water (herbal blend triphala kashaya) for 6 minutes over the eyelid while eye is closed
3.3. 5th day, bandage removed and advised to discharge on 6th day
4. Blood letting: para-surgical procedure on 7th day

Blood letting by medicinal leeches
A non-poisonous variety of leeches called kapila was selected for the procedure.

Preparation of the patient
The patient should be made to lie down. The whole face should be covered and except the eye where leeches are to be applied.

Preparation of leeches
The leeches should be grasped and a mixture of mustard and turmeric paste in water should be applied upon them and then for 48 minutes they should be kept in a vessel of water.

Application of leeches
Medium sized (0.5-1.5gm) medicinal leeches were made to suck from inner aspect of both eyelids at a room temperature 28 degrees Celsius. The leeches should be fully covered with fine wet cloth except for the mouth which should be left exposed. When the leech's mouth gets stuck to the site (eyelid) and its middle part becomes raised assuming the shape of a horseshoe it should be known that it is sucking well. In the study leeches were made to suck over the inner surface of both the upper and lower eyelids. When pricking pain or itching is felt by the patient at the site of application the leech should be removed. If it does not withdraw, rock salt should be sprinkled upon its mouth.

Removal of sucked blood from the leeches
When the leech has fallen away its body should be massaged with rice powder and its mouth by sesame oil and rock salt. Its hind part should then be held by the left hand in between the thumb and fingers and it should be slowly and gently squeezed from tail end to mouth by thumb and fingers of the right hand. When completely emptied the leech is left in a vessel of water and should move to and fro in search of food. If the leech which sinks into the water does not move after being left it should again be made to vomit properly until empty. The same leeches should not be used again for the next 7 days to protect them from blood intoxication.

Local treatment at the site of leech application
Wash the eye with the herbal blend triphala kashaya. After bleeding slows, apply an eye bandage using honey and herbal ghee. Bandage is to be removed on the next day followed by eye wash with the herbal blend triphala kashaya.

After the procedure patient was discharged from the hospital and three subsequent blood letting procedures were arranged on every 8th day.

Follow-up
Follow up was arranged on 15th day, 45th day, 75th day and 105th day.
