Retinal migraine is a retinal disease often accompanied by migraine headache and typically affects only one eye. It is caused by ischaemia or vascular spasm in or behind the affected eye. The terms "retinal migraine" and "ocular migraine" are often confused with " visual migraine ", which is a far-more-common symptom of vision loss, resulting ...
Photopsia can present as retinal detachment when examined by an optometrist or ophthalmologist. However, it can also be a sign of uveal melanoma. This condition is extremely rare (affecting 5–7 per 1 million people, typically fair-skinned, blue-eyed northern Europeans). Photopsia should be investigated immediately.

Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4] Retinal detachment is a medical emergency that requires surgery. [2] [3]
For some patients the removal was only performed on one eye, resulting in the anisometropia / aniseikonia. Today, this is rarely a problem because when the lens is removed in cataract surgery, an intraocular lens, or IOL is left in its place. [citation needed] Retinal aniseikonia occur due to forward displacement, stretching or edema of retina. [4]
Proliferative vitreoretinopathy (PVR) is a disease that develops as a complication of rhegmatogenous retinal detachment.PVR occurs in about 8–10% of patients undergoing primary retinal detachment surgery and prevents the successful surgical repair of rhegmatogenous retinal detachment.
