Summary
Optic disc drusen can mimic glaucoma, complicating diagnosis. Early detection and monitoring are crucial for managing visual field changes in patients with optic disc drusen.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
Background:
- Optic disc drusen (ODD) present diagnostic challenges in glaucoma evaluation.
- ODD can alter optic nerve head morphology and cause visual field defects mimicking glaucomatous damage.
Observation:
- A patient presented with severe headaches and was found to have bilateral optic disc drusen.
- Ocular examination revealed elevated intraocular pressure (IOP) of 27 mmHg.
- Visual field testing showed characteristic defects, including inferior hemifield scotomas and an enlarged blind spot.
Findings:
- Following treatment to normalize IOP and symptomatic relief, visual field defects showed progression upon one-year follow-up.
- Electrophysiological testing revealed abnormalities consistent with glaucoma.
Implications:
- This case highlights the critical need for careful differential diagnosis between ODD and glaucoma.
- Long-term monitoring for progressive visual field loss is essential in patients with ODD.
- ODD can lead to glaucomatous-like visual field progression, necessitating comprehensive neuro-ophthalmological assessment.
