|June 1, 1984
Summary
Argon laser trabeculoplasty (ALT) effectively lowers intraocular pressure in progressive low-tension glaucoma. This treatment offers a valuable option between medication and surgery for managing this condition.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Surgical Interventions
Background:
- Progressive low-tension glaucoma presents a challenge in management.
- Identifying effective treatments between medical therapy and surgery is crucial.
Purpose of the Study:
- To evaluate the efficacy of 360-degree argon laser trabeculoplasty (ALT) in phakic eyes with progressive low-tension glaucoma.
- To assess the impact of ALT on diurnal intraocular pressure variation.
Main Methods:
- Twenty-two phakic eyes with progressive low-tension glaucoma underwent 360-degree ALT.
- Diurnal intraocular pressure curves were measured pre- and two months post-treatment in seven eyes.
Main Results:
- Seventy-three percent of eyes (16/22) achieved clinical success at 12 months, with a mean pressure decrease of 4.9 mm Hg.
- ALT reduced mean peak intraocular pressure by 6.17 mm Hg.
- Diurnal pressure variation decreased by 6.2 mm Hg two months post-ALT.
Conclusions:
- Argon laser trabeculoplasty is effective in managing progressive low-tension glaucoma.
- ALT provides 24-hour pressure control and reduces peak intraocular pressure.
- ALT is recommended as an intermediate step between maximal medical therapy and filtering surgery.
