About this trial

This is an interventional treatment trial for Cicatrizing Conjunctivitis

Eligibility Criteria

20 Years - 85 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • age 20-85 years old
  • unilateral or bilateral cicatrizing conjunctivitis
  • severe aqueous deficiency dry eye ( Schirmer I test result of less than 2mm)
  • chronic ocular surface disease score (COCS) over 3 points
  • Oxford scheme over grade III

Exclusion Criteria:

  • active ocular infection
  • active corneal melting
  • severe xerostomia (modified Schirmer I test result of less than 25mm)

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Minor Salivary Gland Transplantation

Arm Description

Cicatrizing conjunctivitis patients that received minor salivary gland transplantation for dry eye treatment.

Outcomes

Primary Outcome Measures

the change of Schirmer's test result (basic tear secretion in mm) from baseline to 12 months after operation
to compare the Schirmer's test between baseline and 12 months after operation. The higher Schirmer's test results, the better tear secretion function.
the change of ocular surface disease index (OSDI) ( ranged from 0-100) from baseline to 12 months after operation
to compare the OSDI between baseline and 12 months after operation. The higher the OSDI value, the worse of subjective ocular surface disease related symptoms.
the change of chronic ocular complication score (COCS) ( ranged from 0-12) from baseline to 12 months after operation
to compare the COCS between baseline and 12 months after operation. The higher the COCS scores, the more ocular surface complications.

Secondary Outcome Measures

the change of conjunctival impression cytology scores (ranged from 0-5) from baseline to 12 months after operation
to compare the scores of conjunctival impression cytology between baseline and 12 months after operation. The higher the conjunctival impression cytology scores, the worse squamous metaplasia of the ocular surface.

5. Study Description

Brief Summary
This is a prospective study that aimed to observe the therapeutic effects of minor salivary gland transplantation for cicatrizing conjunctivitis patients.
Detailed Description
Cicatrizing conjunctivitis can be the common presentation of many ocular surface diseases as Stevens-Johnson syndrome (SJS), mucous membrane pemphigoid (MMP), chemical burn, Sjogren syndrome, chronic graft-versus-host disease (GVHD) and ocular trauma. Ocular dryness in combination with symblepharon and corneal opacity in these patients could lead to the poor visual and life quality, and less favorable prognosis of ocular reconstruction. This study aims to prospectively evaluate the therapeutic effects of minor salivary gland transplantation for cicatrizing conjunctivitis. The investigators evaluate the saliva-tear productivity (functional outcome) and the survival of graft (anatomical outcome) every three months. The investigators would also validate whether minor salivary gland transplantation is beneficial for the participant prior to further ocular reconstruction as limbal transplantation and corneal grafting.

Arm Type
Experimental
Arm Description
Cicatrizing conjunctivitis patients that received minor salivary gland transplantation for dry eye treatment.
Intervention Type
Procedure
Intervention Name(s)
minor salivary gland transplantation
Intervention Description
The investigators will harvest the autologous labial salivary gland tissue and transplant to the upper and lower conjunctival fornix of the lesion eye.
Primary Outcome Measure Information:
Title
the change of Schirmer's test result (basic tear secretion in mm) from baseline to 12 months after operation
Description
to compare the Schirmer's test between baseline and 12 months after operation. The higher Schirmer's test results, the better tear secretion function.
Time Frame
the Schirmer's test will be performed every three months until 12 months after operation
Title
the change of ocular surface disease index (OSDI) ( ranged from 0-100) from baseline to 12 months after operation
Description
to compare the OSDI between baseline and 12 months after operation. The higher the OSDI value, the worse of subjective ocular surface disease related symptoms.
Time Frame
the OSDI will be monitored every three months until 12 months
Title
the change of chronic ocular complication score (COCS) ( ranged from 0-12) from baseline to 12 months after operation
Description
to compare the COCS between baseline and 12 months after operation. The higher the COCS scores, the more ocular surface complications.
Time Frame
the COCS will be monitored every three months until 12 months after operation
Secondary Outcome Measure Information:
Title
the change of conjunctival impression cytology scores (ranged from 0-5) from baseline to 12 months after operation
Description
to compare the scores of conjunctival impression cytology between baseline and 12 months after operation. The higher the conjunctival impression cytology scores, the worse squamous metaplasia of the ocular surface.
Time Frame
the impression cytology will be performed every three months until 12 months after operation
