Differential Diagnosis for Seeing Floaters when Reading or Studying
- Single most likely diagnosis
- Vitreous Floaters: This is the most common cause of seeing floaters, especially when reading or studying. Floaters are small, shadowy spots that appear in the visual field due to the presence of tiny clumps or cells in the vitreous gel that fills the eye. They are more noticeable when looking at bright or plain backgrounds, such as a white page while reading.
- Other Likely diagnoses
- Dry Eye Syndrome: Dry eyes can cause irritation and discomfort, leading to the sensation of seeing floaters, especially during activities that reduce tear production, like reading or studying.
- Migraines: Some people experience visual auras during migraines, which can include seeing floaters or other visual disturbances.
- Eye Strain: Prolonged reading or studying can cause eye strain, leading to the perception of floaters due to fatigue of the eye muscles.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Retinal Detachment: Although less common, seeing new or sudden floaters, especially accompanied by flashes of light or a curtain descending over the visual field, can be a symptom of retinal detachment, which is a medical emergency.
- Posterior Vitreous Detachment (PVD): Similar to retinal detachment, PVD can cause sudden onset of floaters and flashes. While often benign, it can increase the risk of retinal detachment.
- Rare diagnoses
- Ocular Tumors: Rarely, floaters can be a symptom of ocular tumors, such as lymphoma or melanoma, affecting the eye.
- Intraocular Inflammation (Uveitis): Certain types of uveitis can cause floaters due to inflammation within the eye.
- Diabetic Retinopathy: In advanced stages, diabetic retinopathy can lead to the formation of new blood vessels that can bleed, causing sudden vision changes, including seeing floaters.
