  Purpose

The purpose of this study is to determine if there is any difference in the surgical time when the surgery is performed with a graft taken from under the upper lid versus lower lid. The investigators will also be recording the level of pain felt by patients after surgery, any difficulties during or after surgery, and if the pterygium grows back.


Condition Intervention
Pterygium
 Procedure: Location of the autograft taken following pterygium excision

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Prospective Randomized Pilot Study Comparing the Surgical Times Between Inferior Versus Superior Conjunctival Autografts for Primary Pterygia

Further study details as provided by University Health Network, Toronto:

Primary Outcome Measures:

Secondary Outcome Measures:
  • Visual Analog Pain Score [ Time Frame: 1 week ] [ Designated as safety issue: No ]
  • Recurrence of pterygium [ Time Frame: 1 year ] [ Designated as safety issue: No ]
  • Intraoperative and Postoperative Complications [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 40
Study Start Date: October 2010
Estimated Study Completion Date: October 2012
Estimated Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Superior Conjunctival Autograft
Conjunctival autograft following pterygium excision is taken from superior conjunctival tissue.
 Procedure: Location of the autograft taken following pterygium excision
Following pterygium excision, a conjunctival autograft is taken from either the superior or inferior conjunctiva.
Experimental: Inferior Conjunctival Autograft
Conjunctival autograft following pterygium excision is taken from inferior conjunctival tissue.
 Procedure: Location of the autograft taken following pterygium excision
Following pterygium excision, a conjunctival autograft is taken from either the superior or inferior conjunctiva.

  Eligibility

Ages Eligible for Study:   19 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Primary pterygium (no previous surgeries or radiotherapy) requiring excision due to ocular discomfort or disruption in vision
  • Ability to understand the nature of the procedure and to complete all measurement requirements
  • Patients must be eligible for either the superior or inferior conjunctival autografts (they must not meet any of the following exclusion criteria)
  • Adults (age >18)

Exclusion Criteria:

  • Ocular surface disease apart from pterygium (such as severe dry eye, corneal disease, scarring from previous infection, radiotherapy, inflammatory diseases or trauma)
  • Patients who have had previous ocular surface surgery
  • Patients with glaucoma or those who may need glaucoma surgery in the future
  • Contraindications to local anesthetics (such as known allergy)
  • Pregnancy (as the risk to the fetus with the use of topical antibiotic drops and local anesthetics are not known)
