Differential Diagnosis for Vision Loss Described as a Curtain Over the Eye
- Single Most Likely Diagnosis
- Retinal Detachment: This condition is characterized by the separation of the retina from the underlying tissue, and patients often describe a curtain or shadow descending over their visual field. The symptomatology matches closely with the patient's complaint.
- Other Likely Diagnoses
- Vitreous Detachment: Posterior vitreous detachment can cause floaters and flashes of light, but in some cases, it might be perceived as a curtain, especially if it's associated with retinal tears.
- Migraine Aura: Some individuals with migraines experience visual auras that can include zigzag patterns or a feeling of a curtain descending over their vision, though this is typically bilateral and accompanied by headache.
- Do Not Miss Diagnoses
- Stroke or Transient Ischemic Attack (TIA): Although less common, a stroke or TIA affecting the visual pathways can cause sudden vision loss, which might be described in various ways, including as a curtain. Missing this diagnosis could be catastrophic.
- Optic Neuritis: Inflammation of the optic nerve can cause sudden vision loss, pain on eye movement, and might be perceived as a curtain descending, especially if the condition progresses rapidly.
- Rare Diagnoses
- Choroidal Detachment: Though less common, choroidal detachment can cause vision changes, including a sensation of a curtain over the eye, especially if it involves a significant portion of the choroid.
- Uveitis: Certain types of uveitis, particularly those involving the posterior segment, can cause significant vision disturbances, including a sensation of a curtain, though this would typically be accompanied by other symptoms like pain and redness.
