Early changes in vision
In the early stages, symptoms may be minimal or not noticeable. Vision may still appear normal, even though subtle changes are developing within the macula.
Because of this, many individuals are unaware of the condition in its early stages.
Blurred central vision
One of the most common symptoms is blurring in the centre of vision. This may make it more difficult to read, recognise faces or focus on fine detail.
The blurring may be mild at first and become more noticeable over time.
Distortion of vision
Straight lines may appear wavy, bent or distorted. This can affect how objects are perceived and may make reading or viewing structured patterns more difficult.
Distortion is often one of the more noticeable early changes.
Difficulty with detailed tasks
Tasks that require visual precision, such as reading, writing or recognising faces, may become more challenging.
Individuals may find that they need more light or increased focus to complete these tasks.
Changes in central clarity
There may be areas in the centre of vision that appear less clear or slightly obscured. These changes can vary in size and may become more noticeable over time.
Reduced contrast sensitivity
Objects may appear less distinct from their background, particularly in low-contrast environments. This can affect reading and recognising objects in certain lighting conditions.
Difficulty in low-light conditions
Vision may be less effective in dim lighting or when transitioning between light and dark environments. This can contribute to visual discomfort and reduced clarity.
Changes in colour perception
Colours may appear less vibrant or more difficult to distinguish. This can affect visual quality and the perception of detail.
Differences in symptom pattern
AMD includes different forms that can present with slightly different symptom patterns. In more gradual forms, changes in vision tend to develop slowly over time, often beginning with subtle blurring or difficulty with fine detail.
In more active forms, symptoms may appear more quickly and can include more noticeable distortion or sudden changes in central vision.
Understanding these differences helps in recognising when changes may require more urgent assessment.
Peripheral vision remains intact
AMD primarily affects central vision. Peripheral (side) vision is usually preserved, allowing individuals to maintain general awareness of their surroundings.
Why symptoms may be overlooked
Early symptoms may be subtle and easily attributed to normal ageing or changes in vision. Because one eye can compensate for the other, changes may go unnoticed initially.
