H53-H54: Visual disturbances and blindness

Visual disturbances and blindness, classified under the group range of H53-H54, refer to a collection of conditions that affect an individual's eyesight. These conditions interfere with the healthy functioning of the eyes, resulting in decreased vision or lack of vision. They can be caused by a wide range of issues, including damage to the eye, conditions like diabetes or glaucoma, or even genetic factors. The common symptoms across these conditions typically include blurred vision, spots or floaters in the visual field, and complete loss of vision. These symptoms may present gradually or suddenly, depending upon the underlying condition. The progression of these conditions varies greatly - while some ailments may cause only temporary disturbances, others can lead to permanent blindness. The eyes are the primary system affected by these conditions, but given the role of vision in overall functioning, the impacts can be broad and significant.
