Retinal Risks in High Myopia After Head Trauma - Ophthalmology

More Info

When it comes to understanding the risks of retinal issues, particularly in individuals with high myopia (nearsightedness), after experiencing head trauma, it is essential to consider several factors. High myopia is associated with an increased risk of retinal complications, including retinal tears and detachments. This risk is further compounded by any trauma to the head, as the forces involved can potentially affect the retina, even if the eye itself is not directly impacted.

In your case, you mentioned having a history of high myopia (around 1000 degrees) and previous laser treatment for retinal issues. Following the head trauma from being hit by a ball, you experienced some changes in your retinal condition, such as thinning, which required additional laser treatment. This history is significant because individuals with high myopia often have structural changes in the eye that predispose them to retinal problems. The trauma you experienced could have exacerbated these pre-existing conditions.

The question of whether the incident of pressing your palm against your eye while sleeping poses a similar risk to that of head trauma is nuanced. While pressing on the eye can cause discomfort and transient changes in vision, it is generally less likely to cause the same level of risk for retinal detachment as a significant head injury. However, any pressure on the eye can potentially lead to complications, especially in someone with a history of retinal issues. It is crucial to monitor any symptoms that arise after such incidents.

The primary concern with head trauma leading to retinal detachment is the potential for mechanical forces to create tears in the retina or to cause the retina to pull away from the underlying tissue. This can occur due to the sudden movement of the eye within the orbit or due to changes in the vitreous gel that fills the eye, which can happen after trauma. In high myopia, the retina is already more susceptible to these types of injuries due to its thinner structure.

Regarding follow-up care, if your dilated eye exam shows no signs of retinal detachment or other complications, it may be reasonable to follow a less frequent monitoring schedule than every 1-2 months. However, given your history of high myopia and previous retinal treatments, it is advisable to maintain regular check-ups with your ophthalmologist. The frequency of these visits can be determined based on your specific risk factors and the findings from your examinations.
In general, you should be vigilant for any new symptoms, such as sudden flashes of light, an increase in floaters, or any significant changes in your vision. If you experience any of these symptoms, it is crucial to seek immediate medical attention, as they could indicate a retinal tear or detachment.

In summary, while the risk of retinal detachment from pressing on the eye is lower than from head trauma, it is still essential to be cautious, especially given your history of high myopia and previous retinal treatments. Regular follow-up with your eye care provider is vital to monitor your eye health and to address any concerns that may arise promptly.
