Monocular Pelopsia

Monocular pelopsia is a condition where objects appear closer than they actually are, affecting only one eye. It can cause discomfort and difficulty in judging distances accurately. Understanding its causes, symptoms, and treatment options is crucial for managing this condition effectively.

Monocular pelopsia refers to a visual distortion where objects appear closer than they are in reality. Unlike binocular pelopsia, which affects both eyes, monocular pelopsia specifically impacts one eye. This can lead to challenges in depth perception and spatial awareness.

Types:

There are no distinct types of monocular pelopsia; however, it can manifest differently based on underlying causes such as ocular conditions, neurological disorders, or medications.

Causes:

1. Refractive Errors: Astigmatism, nearsightedness, or farsightedness can contribute to monocular pelopsia.
2. Cataracts: Clouding of the lens in the eye can distort vision.
3. Glaucoma: Increased pressure in the eye can affect vision.
4. Macular Degeneration: Damage to the macula can cause visual distortions.
5. Retinal Detachment: Separation of the retina from its supporting tissues can lead to visual disturbances.
6. Optic Neuritis: Inflammation of the optic nerve can affect vision.
7. Migraines: Visual auras associated with migraines may cause monocular pelopsia.
8. Medications: Certain drugs, such as anticonvulsants or antidepressants, can affect vision.
9. Traumatic Brain Injury: Head trauma can result in visual disturbances.
10. Diabetes: Diabetic retinopathy can cause vision changes.
11. Stroke: Damage to the brain can impact visual processing.
12. Multiple Sclerosis: Neurological conditions like MS can affect optic nerve function.
13. Tumors: Brain or ocular tumors may compress visual pathways.
14. Ocular Infections: Infections such as uveitis can lead to visual impairment.
15. Eye Surgery Complications: Complications from procedures like LASIK can cause visual distortions.
16. Retinal Disorders: Conditions like retinitis pigmentosa can affect vision.
17. Ocular Migraines: Migraine headaches accompanied by visual disturbances.
18. Presbyopia: Age-related loss of near vision can contribute to monocular pelopsia.
19. Environmental Factors: Poor lighting conditions or excessive screen time can strain the eyes.
20. Genetic Predisposition: Family history of eye disorders may increase the risk.
