The retina is a thin, light-sensitive layer at the back of the eye. It works like the film or sensor of a camera: ● Light enters the eye and falls on the retina ● The retina converts light into electrical signals ● These signals are sent to the brain through the optic nerve ● The brain then forms the images we see A healthy retina is essential for clear vision, color perception, and seeing in low light. 

Some common retinal conditions include: ● Diabetic Retinopathy ● Age-Related Macular Degeneration (AMD) ● Retinal Detachment ● Retinal Vein Occlusion ● Macular Edema ● Macular Hole ● Epiretinal Membrane ● Inherited retinal disorders 

Symptoms may vary but commonly include: - Blurred or distorted vision - Sudden or gradual vision loss - Dark spots or shadows in vision - Flashes of light or floaters - Difficulty reading or seeing fine details

Risk factors include: - Diabetes - Aging - High blood pressure - High cholesterol - Family history of retinal disease - High myopia (high minus power) - Smoking

Diagnosis may involve: ● Dilated retinal examination ● Retinal photography ● Optical Coherence Tomography (OCT) ● Fundus Fluorescein Angiography (FFA) ● Ultrasound of the eye (in certain cases) 

Medications (Eye Injections) Special medicines (anti-VEGF or steroids) are injected into the eye to reduce swelling and stop abnormal blood vessel growth. Commonly used for diabetic retinopathy, diabetic macular edema, and age-related macular degeneration. ● Laser Treatment Laser is used to seal leaking blood vessels or prevent further retinal damage. Used in diabetic retinopathy, retinal tears, and some vein blockages. ● Retinal Surgery (Vitrectomy) A microsurgery d
