Effect of ocular compression on intraocular pressure.
Ophthalmic Surgery
|September 1, 1985
Summary
Forty minutes of eye compression using the Honan intraocular pressure reducer significantly lowered intraocular pressure more than five minutes. This study found no adverse effects from ocular compression.
Area of Science:
- Ophthalmology
- Physiology
Background:
- Ocular compression is used to reduce intraocular pressure.
- The optimal duration for external ocular compression is not well-established.
Purpose of the Study:
- To investigate the effect of different compression durations on intraocular pressure.
- To evaluate the safety of prolonged ocular compression.
Main Methods:
- Prospective, double-blind, controlled study.
- Normal subjects received ocular compression using the Honan intraocular pressure reducer (HIPR) for either five or 40 minutes.
- Intraocular pressure was measured before and after compression.
Main Results:
- A 40-minute application of HIPR resulted in a significantly greater decrease in intraocular pressure (14.3 mmHg) compared to a five-minute application (8.8 mmHg).
- The difference in pressure reduction between the two durations was statistically significant (p < 0.02).
- No adverse effects were observed in any participants.
Conclusions:
- Prolonged ocular compression (40 minutes) is more effective in reducing intraocular pressure than shorter durations (5 minutes).
- External ocular compression using HIPR appears safe for normal subjects.
- Further research into the physiological effects of external ocular compression is warranted.
