Study Summary

Dry Eye Disease (DED) is a multifactorial pathology characterized by inflammation of the lacrimal functional unit that develops in ocular surface pathology, severely affecting patients quality of life. The core of the treatment relies at present in antinflammatory topical therapies, which are still scarce.

The investigators hypothesize that osteopathy-based techniques may help these patients by influencing the central involvement regarding parasympathetic innervation of tear and saliva-secreting glands.

The aim of this osteopathic treatment protocol is to release the involved structures in the tear-secreting system innervation, such as the sphenopalatine ganglion. In addition, this ganglion innervates the minor salivary glands, therefore it is intended to help patients suffering from xerostomia.

The hypothesis then is that a systemic protocol treatment can help balance both parts of the vegetative nervous system (sympathetic and parasympathetic) with the objective of increasing the secretion of tear and saliva in patients with ocular and oral dryness (DED and xerostomia, respectively), thus improving their clinical situation.

This osteopathic protocol does not have the potential to cause adverse effects. The main objective is to analyze the efficacy of this protocol application in terms of improving symptoms and signs of ocular and oral dryness, tear film quality and inflammation molecule levels in tears and saliva.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • > 18 years old.

  • Patients diagnosed with Dry eye disease (DED) and suffering symptoms of ocular andoral dryness for at least 6 months.

  • "Dry eye" symptoms must have a score of > 2 (0-4 range) in mSIDEQ questionnaire.

  • Ocularly symptomatic patients (OSDI > 12) despite the medication, medical devicesand/or therapeutic measures carried out until the inclusion.

  • Symptomatic patients in terms of oral dryness (XI-Sp > 11) despite the medication,medical devices and/or therapeutic measures carried out until the inclusion.

  • Schirmer I test, without topical anesthesia, must have an initial value of ≥ 1 mmand <10 mm.

  • Not included in any other clinical pharmacological trial or study (medical devicesare excluded) in the last 3 months.

  • Signed informed consent and ability to complete all study visits.

Exclusion

Exclusion Criteria:

  • Irreversible anatomical alteration of the lacrimal glands (watery, sebaceous ormucinic) or salivary, surgeries or by healing processes that affect eyelids and/orconjunctiva.

  • Alteration in the autonomic nervous system.

  • Another active ocular surface disease different from that caused by DED.

  • Oral diseases, inflammations or acute injuries in the mouth (trauma, surgicalintervention, etc.) in the last month or healing processes of the oral mucosa.

  • Use of cyclosporine or topical tacrolimus started within < 3 months and/or steroidsor blood derivatives started within < 1 month and that will not be maintained duringthe study.

  • Use of orally drugs with exocrine hyposecretory side effects or that may affect theparasympathetic nervous system, unless the dose is stable during the previous monthto inclusion and whose dose is not expected to vary throughout this study.

  • Patients may be using any other medication, topical or systemic, unless the dose arethe same for the duration of the study.

  • Patients may be using artificial tears, moisturizers in general or bloodderivatives, unless the dose was the same in the last month and has to be maintainedat the same dose for the duration of the study.

  • To have had any "in-office" method to manage DED or Meibomian gland dysfunction (pulsed light, thermal massages, etc.) in the last 6 months.

  • Occlusion of the lacrimal puncta in the last month.

  • Local (in cranial sphere) or general anesthesia in the last 3 months.

  • Use of contact lenses, unless they stop using them for at least one week beforeinclusion and one week before each visit

Study Description

This clinical study intended to offer an alternative therapeutic tool for a disease, dry eye, that is highly prevalent, causes a decreased in the quality of life and work productivity, and whose pharmacologic treatment is very limited.

The osteopathy protocol consists of an initial assessment of the cranial vault and 7 techniques through which the different structures involved are treated and are as follows: 1) balance of the cranio-sacral system; 2) reharmonization of sphenobasilar synchondrosis; 3) and 4) release of the bony components in the pterygo-palatine fossa (maxillas and sphenoid); 5) and 6) release of the bony components in relation with the main lacrimal gland (frontal and front-malar suture); and 7) sphenopalatine ganglion stimulation. The patient is always in supine position and the investigator is standing on the side.

The proposed osteopathy protocol is innocuous, with no possible adverse effects. The main objective is to analyze the efficacy of this protocol application in terms of improving symptoms and signs of ocular and oral dryness, tear film quality and inflammation molecule levels in tears and saliva.

Recruited patients will have dry eye disease (and subsequently ocular dryness) and oral dryness (xerostomia). Inclusion/exclusion criteria are detailed in the corresponding section below, as well as all outcome measures.

All COVID19-related sanitary regulations will be strictly followed.
