Summary
Nearly 40% of patients with high intraocular pressure (IOP) but no glaucoma signs progressed to the disease. The ibopamine provocation test became positive over time, highlighting the benefit of early ocular hypotensive therapy.
Area of Science:
- Ophthalmology
- Glaucoma Research
- Ocular Physiology
Background:
- Elevated intraocular pressure (IOP) without clinical signs of glaucoma presents a diagnostic challenge.
- Understanding disease progression and predictive markers is crucial for early intervention.
Purpose of the Study:
- To determine the incidence of glaucoma development in patients with elevated IOP.
- To evaluate the efficacy of preventive ocular hypotensive therapy.
- To assess changes in the ibopamine provocation test response over time.
Main Methods:
- Retrospective 12-year study of 35 patients with IOP > 21 mmHg.
- Monitoring for evolution to glaucomatous disease.
- Serial administration of the ibopamine provocation test.
- Evaluation of ocular hypotensive therapy initiation.
Main Results:
- 39.13% of eyes evolved to glaucoma over 12 years.
- Ibopamine test positivity increased significantly from baseline (48.14% in evolving eyes, 66.66% in stable eyes) to study end (92-95% positive).
- Early ocular hypotensive therapy correlated with test positivity.
Conclusions:
- A significant proportion of individuals with ocular hypertension progress to glaucoma.
- The ibopamine provocation test demonstrates increasing positivity over time, suggesting worsening outflow pathway compromise.
- Early initiation of ocular hypotensive therapy is vital and appears to influence test outcomes.
