Post-Stroke vision problem

What the stats reveal!

In 2006, the Third National Health and Morbidity Survey spilled the beans that 0.3% of Malaysians had strokes. Fast forward to 2011, and that number doubled to 0.7%, with a spike in different age groups, reaching 7.8% in folks 75 and older.

Here’s the scoop on what those stroke survivors faced: 27% grappled with wonky visual fields, 20% had eye movement hiccups, 4% wrestled with dimmed vision, and 2% tackled tricky perception issues. Surprise, surprise – 15% played host to a combo platter of these vision challenges.

Post-stroke visual anomaly ?

So, why the vision hiccups after a stroke? Blame it on the brain damage, which messes with both the eyes and the brain’s visual processing center. Depending on where the brain takes a hit, different vision troubles pop up.

Neuro-Optometric Vision rehabilitation is important to maximize the patient’s visual function. These wizards team up with physio and occupational therapists, working their magic to boost vision skills in reading, moving around, and tackling everyday tasks. Stroke survivors, prepare to learn some fresh moves with these vision-savvy allies!

Let’s break down the vision hiccups after a stroke:

(i) Visual field loss

Ever heard of central and peripheral vision? Well, if a stroke messes with your central vision, it’s like trying to see the world from the edges – no sight in the center. Peripheral vision loss, on the other hand, narrows your view to just one side, either right or left.

(ii) Eye movement problems

Picture this: your eyes acting like they’re on a roller coaster. That’s what happens with eye movement problems post-stroke. Judging distances becomes a puzzle, shifting your gaze from one thing to another gets tricky, and to top it off, things might seem a bit shaky – a condition called nystagmus.

(iii) Visual processing problems

When the brain’s visual receiver goes haywire after a stroke, it leads to visual processing problems – also known as visual neglect. The brain starts ignoring info from one side of the eye, making it hard for the patient to tell left from right.

Patients with stroke after visited an Ophthalmologist should visit a Neuro-optometrist who specialized in Neuro-Optometric Vision rehabilitation so that they can advise the best and most suitable treatment plans.  Visual field loss usually can be treated with different optical aids.

Binocular Vision Dysfunction (BVD) is a condition that can occur after a traumatic brain injury and can cause anxiety and panic attacks because the eyes are not aligned properly. Symptoms of BVD include seeing double, being sensitive to light, having trouble judging distances, difficulty reading, having a shorter attention span, feeling dizzy or disoriented, struggling to navigate through crowds, feeling anxious, experiencing nausea, and having pain in the neck and shoulders. In severe cases, BVD can lead to agoraphobia. Medications for anxiety may not help with BVD-related anxiety and could make symptoms worse. A Functional Vision Evaluation can diagnose BVD, and treatment involves using special lenses called prism spatial lenses to realign vision. This can reduce symptoms by 30-50% immediately and up to 70-80% with consistent use. Neuro-optometric rehabilitation, along with prism lenses, can address the underlying issue.

Binocular Vision Dysfunction

Binocular Vision Dysfunction (BVD) is a condition where the eyes do not work together properly, which can cause double vision or vertical heterophoria. Symptoms include headaches, dizziness, trouble reading, and feeling anxious in crowded places. It is recommended that children and adults, especially those with difficulty reading, head injuries, or developmental delays, have regular eye exams. These exams assess how well the eyes work together, focus, and move.

Is Panic Attacks related to vision?

Is Panic Attacks related to vision?

Panic attacks, marked by intense anxiety and physical symptoms, are linked to the activation of the sympathetic nervous system. The vagus nerve plays a key role in these responses, with techniques like the Valsalva maneuver helping regulate heart rate and blood pressure. Vergence therapy, which involves voluntary eye convergence, is being explored as a potential treatment. The oculo-cardiac reflex, known to influence heart rate, is also significant in this context.
