An eyelid stye, or chalazion, is the most common eyelid ailment, and is caused by the blockage of one of the oil secreting glands of the eyelid (meibomian glands). This leads to a typically painful, swollen, and red eyelid bump that lasts from days to weeks and months. The chalazion may cause tearing, pressure on the cornea, and irritation, all of which contribute to its morbidity. There are many anecdotal first line treatments for this condition, including warm compresses to the eyelid, topical antibiotics, topical steroids, topical combination antibiotic/steroid, and oral antibiotics. There have been no clinical trials to compare the efficacy of any of these conservative treatments. We wish to determine the most effective conservative medical treatment for chalazia.

Primary Outcome Measures:
  • Complete resolution [ Time Frame: 4-6 weeks ]
    Defined as chalazion size regression of 100%

Secondary Outcome Measures:
  • Chalazion Size Difference Post-Treatment [ Time Frame: 4-6 weeks ]
    Change of size of eyelid chalazion in mm

  • Percent chalazion size improvement [ Time Frame: 4-6 weeks ]

Enrollment: 150
Study Start Date: November 2010
Study Completion Date: March 2016
Primary Completion Date: January 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Hot Compress
Patients in the hot compress arm will be shown how to apply hot compresses to the affected lid and gently massage the lid to encourage the chalazion to spontaneously drain for 5 minutes, 3x/day.
Other: Hot Compresses
Hot compresses 3x/day to eyelids
Active Comparator: Tobrex Drops and Ointment
Patients in the Tobrex arm will be prescribed Tobrex drops 3x/day and ointment to be applied before bedtime.
Drug: Tobrex Drops and Ointment
Tobrex drops will be given to the affected eye 3x/day, and Tobrex ointment will be given at night before bed.
Other Names:
  • Aktob
  • Tobralcon
  • Tobrasol
  • Tobramycin
Active Comparator: Tobradex Drops and Ointment
Patients in the Tobradex arm will be prescribed Tobradex drops 3x/day and ointment to be applied before bedtime.
Drug: Tobradex Drops and Ointment
Tobradex drops will be given to the affected eye 3x/day, and Tobradex ointment will be given at night before bed.
Other Name: Tobramycin/dexamethasone
