简要总结
The purpose of this study is to compare the efficacy and side effects of topical Loteprendol etabonate 0.5% (Lotemax) versus Dexamethasone 0.1% (Sterodex) following strabismus surgery.
详细描述
This is a randomized prospective study that will involve 100 patients (males and females) undergoing strabismus surgery. All patients will be randomly assigned to receive one of the study drugs (Loteprendol etabonate 0.5% (Lotemax) drops or Dexamethasone 0.1% (Sterodex) drops) after undergoing strabismus surgery. In addition to the study drug all patients (in both groups) will receive topical Ofloxacin 0.3% (Oflox) eye drops. All patients will undergo a complete ophthalmological evaluation before surgery including orthoptic assessment of their strabismus and measurement of intraocular pressure (IOP). Topical treatment with the study drug and topical Ofloxacin 0.3% (Oflox) eye drops will begin on the evening of the surgery, following a schedule that will be the same for both groups: 4 times daily during the first week, 3 times daily for the second group, twice daily for the third week, and as needed for the fourth week. All patients will be examined at 1 day, 1 week, 2 weeks and 4 weeks after surgery by a masked investigator (not the strabismus surgeon).
The parameters to be checked will include:
- Patient pain and discomfort
- Conjunctival chemosis
- Conjunctival hyperaemia
- Conjunctival discharge
- Conjunctival gap
- Intraocular pressure (IOP)
- Number of pain control medications taken

研究组 & 干预措施
Loteprendol
Topical Loteprendol used after strabismus surgery
干预措施: Loteprendol etabonate 0.5% (Drug)
Dexamethasone
Topical Dexamethasone used after strabismus surgery
干预措施: Dexamethasone 0.1% (Drug)
结局指标
主要结局
Change from baseline - Intraocular pressure (IOP)
时间窗: 1 day before surgery (basline), and 1 day, 1 week, 2 weeks, 4 weeks after surgery
IOP will be measured by Goldmann applantation tonometry one day before surgery (baseline IOP). In patients in whom Goldmann tonometry is impossible, ICARE tonometer will be used instead. IOP will be measured 1 day, 1 week, 2 weeks, 4 weeks after surgery, at each time point change from baseline IOP will be recorded.
Change from baseline - Conjunctival hyperemia
时间窗: 1 day before surgery (basline), and 1 day, 1 week, 2 weeks, 4 weeks after surgery
Conjunctival hyepremia will be measured one day before surgery (basline measurement) using the following scale: 0=no hyperemia, 1=mild (less than one quadrant), 2=moderate (less than half of the conjunctival surface), 3= severe (less than half of the conjunctival surface). Conjunctival hyperemia will be measured 1 day, 1 week, 2 weeks, 4 weeks after surgery, at each time point change from baseline measurement will be recorded.
