Thank you for your response. The second doctor I went to for an exam was a retinal specialist in one of the best eye clinic in my country, and they did check my retina with scleral depression, and said there is no retinal bleeding, tear or detachment. I will have another appointment in two weeks, and I will also see a neurologist because I have other problems like migraine, and other types of headache. I have also been under lots of stress in the last few weeks and have not been sleeping well, and have a very low blood pressure.
Could you also tell me what do flashes of light that are symptom of RD look like? Because mine are very small, brief dots that are sometimes black and sometimes bright, and there is only one at a time, so there aren´t many of them at the same time. They also happen when I am very tired, or when I am climbing upstairs.
See a retinal specialist for a second opinion. Flashes of light can indicate a retinal tear/detachment, and these are easily detected on a careful dilated exam of the retina with scleral depression. An OCT is mainly used for macular evaluations and does not rule out a retinal detachment.
