Photopsia
Photopsia is a symptom of health conditions that affect the eye, including a detached retina and age-related macular degeneration. It is sometimes referred as eye floaters or eye flashes.
Photopsia is a visual phenomenon characterized by seeing flashes of light or flickering lights without an external light source. These flashes can appear as sparks, lightning bolts, or shimmering lights.They can disappear as quickly as they appear or they can be permanent.
Types:
• Positive Photopsia: Involves seeing actual light flashes or sparkles.
• Negative Photopsia: Involves seeing dark spots or shadows.
Symptoms:
• Flashes of light: Often described as bright streaks, sparks, or twinkling lights.
• Flickering lights: May occur in the peripheral vision or across the entire visual field.
• Floaters: Some people experience floaters alongside photopsia, which are small, dark shapes that drift across the vision.
Causes:
• Vitreous detachment: As people age, the gel-like vitreous inside the eye can shrink and pull away from the retina, causing flashes of light.
• Migraine: Some migraine sufferers experience visual disturbances, including photopsia, before or during a migraine attack.
• Retinal tear or detachment: When the retina detaches or tears, it can cause flashes of light.
• Ocular migraines: These can cause temporary visual disturbances, including flashes of light, without the accompanying headache.
• Posterior vitreous detachment (PVD): In this condition, the vitreous gel separates from the retina, leading to photopsia.
• Retinal artery or vein occlusion: Reduced blood flow to the retina can cause visual symptoms, including photopsia.
• Trauma: Injury to the eye can cause photopsia.
• Tumors: Rarely, tumors affecting the eye or brain can lead to photopsia.
Risk Factors:
• Age: Photopsia is more common in older adults due to changes in the vitreous gel.
• Eye trauma: People who have experienced eye injuries are at higher risk.
• History of migraines: Individuals with a history of migraines may be more prone to photopsia.
• High myopia: Severe nearsightedness increases the risk of retinal tears or detachments, which can cause photopsia.
Complications:
• Retinal detachment: If left untreated, photopsia caused by a retinal tear or detachment can lead to permanent vision loss.
• Vision loss: In some cases, photopsia may be a symptom of an underlying condition that can cause permanent vision impairment if not addressed.
Diagnosis:
• Comprehensive eye examination: This may include visual acuity tests, pupil dilation, and examination of the retina.
• Fundus photography: A photograph of the back of the eye can help identify any abnormalities.
• Optical coherence tomography (OCT): This imaging test provides detailed images of the retina and can detect retinal abnormalities.
• Fluorescein angiography: This test involves injecting a dye into the bloodstream to highlight blood vessels in the retina, helping to identify any blockages or leaks.
Treatment:
• Vitreous detachment: Often requires no treatment, but patients should have regular eye exams to monitor for any complications.
• Retinal tears or detachment: May require laser surgery or cryotherapy to seal the tear or reattach the retina.
• Migraine management: Treating migraines with medication and lifestyle changes can help reduce the frequency and severity of visual disturbances.
• Underlying conditions: Treatment of underlying conditions such as diabetes or hypertension may help alleviate photopsia symptoms.
• Avoiding triggers: For individuals prone to photopsia associated with migraines, avoiding triggers such as stress, certain foods, or lack of sleep may help prevent episodes.
Ayurvedic Treatment –
In Ayurveda, the concept of Chakshushya dravya (foods beneficial for eye/vision) and therapeutic procedures is present – which improves or enhances visual acuity (vision). Nasya karma (nasal infusion) and Tarpana (oleation/administration of herbal oils or ghee), Anjana (Colliyrium) are among the procedures reccommended.
Beneficial Medications-
• Saptamrit Lauh
• Amalaki Rasayan
• Triphala Churna
• Mahatriphla Ghrit
Lifestyle Modifications-
• Walk regularly
• Personal hygiene especially avoiding personal contact with those infected should be practiced.
• Wear headgear such as caps and hats, and eye-gear such as sunglasses to protect from UV radiations
• Make sure you get good sleep regularly
• Make it a habit to wake up early
• Massaging ghee on soles is said to be beneficial for general health of eyes in Ayurveda
Conclusion
Photopsia can be a concerning symptom, but it is often treatable, especially when caught early. Regular eye exams are essential for detecting and addressing any underlying issues that may be causing photopsia. If you experience flashes of light or other visual disturbances, it’s important to see an eye care professional for proper evaluation and management.
