retinaleválásos

Retinaleválásos is a Hungarian term that translates to "retinal detachment" in English. This is a serious medical condition where the retina, the light-sensitive tissue at the back of the eye, separates from the underlying layer of blood vessels called the choroid. This separation deprives the retina of oxygen and nutrients, which can lead to vision loss if not treated promptly.

The causes of retinal detachment can vary. Common reasons include a tear or hole in the retina, allowing fluid from the vitreous humor (the jelly-like substance filling the eye) to seep underneath and lift the retina away. This can occur due to age-related changes in the vitreous, trauma to the eye, or certain medical conditions like severe myopia (nearsightedness), diabetes, or inflammatory eye diseases. Sometimes, a blow to the head or eye can also cause it.

Symptoms of retinal detachment often include a sudden appearance of new floaters (small spots or specks that drift in the field of vision), flashes of light (photopsia), and a shadow or curtain that appears to cover a part of the visual field. This shadow typically starts in the peripheral vision and can progress towards the center. Pain is usually not a symptom, which can sometimes delay diagnosis.

Retinal detachment is considered an ophthalmic emergency. Treatment typically involves surgery to reattach the retina. The specific surgical technique used depends on the nature and extent of the detachment, but common procedures include pneumatic retinopexy, scleral buckle surgery, and vitrectomy. Early diagnosis and intervention are crucial to preserving vision.
