Reversible optic disk cupping and visual field improvement in adults with glaucoma

Area of Science:

• Ophthalmology
• Optometry

Background:

• Glaucoma is a progressive optic neuropathy.
• Assessing structural (optic disk) and functional (visual field) changes is crucial for glaucoma management.

Purpose of the Study:

• To evaluate the correlation between changes in optic disk appearance and visual field function over time in glaucoma patients undergoing treatment.
• To determine the impact of intraocular pressure reduction on these changes.

Main Methods:

• Retrospective review of optic disk stereophotographs and visual field perimetry results from adult glaucoma patients.
• Independent masked grading of optic disk and visual field changes (better, worse, unchanged) by three glaucoma specialists.
• Analysis of the association between optic disk/visual field changes and the degree of intraocular pressure reduction.

Main Results:

• A reversal of optic disk cupping was observed in 21% of eyes (16 of 75).
• Visual fields improved in 31% of cases (20 of 63).
• A corresponding change in visual field was noted in 35% of eyes with optic disk changes (6 of 17).
• Significant association (P < .05) found between improved optic disk and visual field appearance and greater intraocular pressure reduction.

Conclusions:

• Treatment for glaucoma can lead to measurable improvements in both optic disk structure and visual field function.
• The degree of intraocular pressure reduction is a significant factor associated with positive changes in glaucoma.
• Monitoring both optic disk and visual field is essential for comprehensive glaucoma assessment.
