[Reversibility of visual field defects in primary open-angle glaucoma]

Area of Science:

• Ophthalmology
• Visual Neuroscience

Background:

• Glaucomatous visual field defects are typically progressive.
• Computerized perimetry is a key tool for monitoring disease progression.
• Reversibility of visual field defects in glaucoma is an important clinical question.

Purpose of the Study:

• To evaluate the reversibility of glaucomatous visual field defects.
• To assess the impact of a new medical therapy on visual field sensitivity.
• To determine the percentage of eyes showing improvement after treatment.

Main Methods:

• 16 patients with uncontrolled open-angle glaucoma underwent visual field analysis.
• Visual field examinations were repeated within 48 hours to minimize learning effects and fluctuation.
• A control group of 10 normal eyes was included for comparison.

Main Results:

• A statistically significant improvement in visual field threshold was observed in 31.7% of eyes after one week of therapy.
• Computerized perimetry allowed for detailed threshold evaluation and statistical analysis.
• The study design aimed to isolate the effect of the new therapy.

Conclusions:

• The study suggests that glaucomatous visual field defects may exhibit some reversibility with medical therapy.
• Computerized perimetry is a reliable method for assessing changes in visual field sensitivity.
• Further research is warranted to explore the long-term effects and mechanisms of visual field improvement in glaucoma.
