This document discusses symptoms of retinal disease such as blurred vision, visual distortions, and flashes of light. It also outlines examination techniques for evaluating the retina, including using direct and indirect ophthalmoscopes, slit lamps with specialized lenses, retinal photos, ultrasound, and angiography to visualize the retina and assess diseases.

1. Symptoms of retinal disease
• Blurred vision
• Distortion of vision, micropsia, colour change
• Loss of central or peripheral field of vision
• Loss of any part of field of vision
• Flashes of white or gold light
• Floaters

2. Retinal examination
• Direct ophthalmoscope
• Indirect ophthalmoscope +
scleral indentation
• Slit lamp + 90D or 3-Mirror
contact lens
• Retinal photos (Optos etc)
• Ultrasound
• Fluorescein & ICG angiography
• OCT & OCT-A
• Electrophysiology (ERG, EOG,
VEPs)
• CT, MRI
