welcome to hcm, I really appreciate your concern, Retinal detachment has different presentation. It usually presents with: Flashing lights, sudden loss of vision and floating objects in the entire field of vision, multiple black dots in visual fields to total blackouts. As you have already undergone 1 surgery for retinal detachment, So, I preferably suggest you to get investigated and physically examined by an Ophthalmologist. Make an appointment as per your ease to get it evaluated in person. There are other reasons which also should be kept in mind regarding your symptoms: *Diabetes Mellitus also leads to some visual abnormalities which differ in different patients depending on the degree of damage to the eyes by Sorbitol (excess glucose deposits in eye). *Eye s outer lining irritation and inflammation also may cause such symptoms as you feel. *Sleep Deprivation is a name of a Syndrome of a Pandora box of symptoms. On top list of that is double vision or diplopia. Anxiety and depression also adds up to this problem. Preventive Measure: Take proper rest. Good night s sleep is a must for a healthy vision and good health overall. Take plenty of fluids especially judicious amount of clean drinking water. If not checked/screened before, get yourself screened for Hypertension and Diabetes Mellitus. No Caffeine containing fluids and foods. Coffee, tea, chocolates, beverages, energy drinks etc etc. Vegetables and salads are good for you. A proper physical activity is necessary for healthy heart and unclogged blood vessels in every organ. Keep it as a habit in everyday life. Please let me know if you have any questions, thanks.regards.
