Macular changes resulting from papilloedema
Abstract:
Six cases are presented with macular changes in association with papilloedema; 4 suffered permanent visual loss. The present paper emphasises this previously infrequent finding and discusses the haemodynamic and mechanical factors responsible. The macular changes consisted of haemorrhages situated in front, within, or behind the retina, and occasionally the results of neovascular membrane formation produced secondary visual loss. Changes in the pigment epithelium were seen in 3 cases associated with choroidal folds. Macular stars rarely produce visual loss. Recognition of these changes is important in the assessment of the visual loss in papilloedema.
Insights
Macular changes associated with papilloedema can cause permanent vision loss. Recognizing these retinal and pigment epithelium changes is crucial for assessing visual impairment in papilloedema cases.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
Background:
- Papilloedema, characterized by optic disc swelling, is often associated with increased intracranial pressure.
- Macular involvement in papilloedema is considered infrequent but can significantly impact visual acuity.
Observation:
- Presents six cases of macular changes occurring alongside papilloedema.
- Observed macular hemorrhages (pre-, intra-, or subretinal), neovascular membrane formation, and pigment epithelium changes with choroidal folds.
Findings:
- Four out of six patients experienced permanent visual loss due to these macular alterations.
- Neovascularization and pigment epithelium changes were noted as causes of secondary visual loss.
- Macular stars, while observed, rarely contributed to significant visual impairment.
Implications:
- Highlights the importance of evaluating macular status in patients with papilloedema.
- Discusses hemodynamic and mechanical factors contributing to macular pathology in this context.
- Emphasizes that recognizing these macular changes is vital for accurate assessment of visual loss severity in papilloedema.
