Study summary

The objective of this study was to evaluate the efficacy of topical 0.2% loteprednol etabonate, a 'soft steroid', compared with topical 0.1% dexamethasone, which is widely used in postoperative pterygium excision to prevent the recurrence of pterygium. If 0.2% loteprednol etabonate is non-inferior in efficacy compared with 0.1% dexamethasone, it may be used postoperatively in pterygium excision patients with the benefit of a low incidence of ocular hypertension or secondary glaucoma.

Read the detailed description

A prospective randomized control trial was performed from October 2015 to April 2019 at the Department of Ophthalmology, Thammasat Hospital, Thailand and Panyananthaphikkhu Chonprathan Medical Center, Thailand.

Subjects Patients who had pterygium excision with amniotic membrane transplantation (AMT) and who had impending recurrent pterygium stage 3 defined as fibrovascular tissue not invading the cornea were included.

Then the participants were randomized into 2 groups. Both groups received subconjunctival 5-fluorouracil (5-FU) injection 5mg/0.1 mL with 27-gauge needle in the area of fibrovascular tissue, and then the eyes were irrigated with 30 mL of normal saline. 0.2% loteprednol etabonate was prescribed in group 1, and 0.1% dexamethasone (CD-oph) was prescribed in group 2 every 4-6 hours for 4 weeks. After that, the regimen was gradually decreased until cessation at 3 months. 5-FU was repeatedly injected monthly in the presence of marked inflammation and not more than 3 times to prevent complications.

All patients were followed-up at 1, 3, 6, and 9 months to assess the impending recurrent pterygium severity score, intraocular pressure, complications, detection of true recurrent pterygium, and time to recurrence.

Study arms

  • Experimental
    0.2% loteprednol etabonate

    This group was treated with subconjunctival 5-FU injection and topical 0.2% loteprednol etabonate every 4-6 hours for 4 weeks. After that, the regimen was gradually decreased until cessation at 3 months.

    Drug: 0.2% loteprednol etabonate

  • Active comparator
    0.1% dexamethasone

    This group was treated with subconjunctival 5-FU injection and topical 0.1% dexamethasone (CD-oph) every 4-6 hours for 4 weeks. After that, the regimen was gradually decreased until cessation at 3 months.

    Drug: 0.1% dexamethasone

Interventions

  • Use topical 0.2% loteprednol etabonate eyedrop every 4-6 hours for 4 weeks. After that, the regimen was gradually decreased until cessation at 3 months.

    Also known as: Alrex

  • Use topical 0.1% dexamethasone eyedrop every 4-6 hours for 4 weeks. After that, the regimen was gradually decreased until cessation at 3 months.

    Also known as: CD-oph

What researchers measure

Primary outcomes

  1. rate of true recurrent pterygium

    true recurrent pterygium is the fibrovascular tissue that invade into cornea

    Time frame: 6 months

Secondary outcomes

  1. severity score of impending recurrent pterygium

    severity score of impending recurrent pterygium included 3 factors; redness, thickness of fibrovascular tissue, and size of fibrovascular tissue at 3 mm from limbus, which are classified into 3 grades in each factor.

    Time frame: 6 months

  2. time to recurrent of pterygium

    time from enrolled participants until they developed true recurrent pterygium

    Time frame: 6 months

  3. rate of steroid induced ocular hypertension

    number of participants in each group who had intraocular pressure \> 21 mmHg

    Time frame: 6 months
