This is what Grok says:
Yes, a partial hanging suicide attempt can potentially damage eyesight due to the effects of strangulation or pressure on critical structures in the neck and head. Here's how it could happen:
1. **Reduced Blood Flow to the Eyes**: Partial hanging can compress the carotid arteries or jugular veins, reducing blood flow to the brain and eyes. This can lead to hypoxia (lack of oxygen) in the retina, potentially causing retinal ischemia or infarction, which may result in temporary or permanent vision loss.
2. **Increased Intracranial Pressure**: The pressure from the ligature can obstruct venous drainage, increasing pressure in the brain and optic nerve. This can cause optic nerve damage or conditions like papilledema, which may impair vision.
3. **Nerve Damage**: Compression of the vagus nerve or other cranial nerves during the attempt could indirectly affect the optic nerve or muscles controlling eye movement, leading to vision problems or double vision.
4. **Petechial Hemorrhages**: Strangulation often causes small blood vessels in the eyes to rupture, leading to petechiae (tiny red spots). While these are usually cosmetic, severe cases might indicate broader vascular damage affecting eyesight.
5. **Traumatic Injury**: If the attempt involves a fall or sudden jerk, it could cause trauma to the head or eyes, potentially damaging the optic nerve or retina.
The extent of damage depends on factors like the duration of compression, the force applied, and how quickly medical intervention occurs. Survivors may experience temporary symptoms like blurred vision or, in severe cases, permanent blindness. Immediate medical evaluation is critical to assess and mitigate damage.
However, I asked:
Wouldnt the blood flow had to be stopped for a while?
And it said:
Yes, for significant damage to eyesight to occur, blood flow to the eyes or brain would typically need to be severely restricted or stopped for a sustained period. The exact duration varies depending on individual physiology and the degree of compression, but here's a breakdown:
- Partial vs. Complete Occlusion: In partial hanging, blood flow through the carotid arteries or jugular veins may be only partially restricted. Even partial obstruction can cause hypoxia or increased pressure in the eyes and brain, but significant damage usually requires near-complete or complete occlusion of blood flow.
- Time Threshold for Damage:
- Retinal Ischemia: The retina is highly sensitive to oxygen deprivation. Noticeable vision impairment can begin within 1–2 minutes of severe hypoxia, with irreversible damage possible after 4–6 minutes if blood flow is completely stopped.
- Optic Nerve Damage: The optic nerve is slightly more resilient but can still be damaged by prolonged pressure or lack of oxygen, typically after several minutes of severe restriction.
- Brain-Related Vision Loss: If the brain's visual cortex is affected by hypoxia, permanent vision issues can occur after 4–10 minutes of insufficient blood flow, depending on the extent of deprivation.
- Partial Hanging Context: In partial hanging, complete cessation of blood flow is less common than in full suspension, so damage might take longer to develop. However, even intermittent or partial compression over minutes can cause cumulative effects like retinal hemorrhages, increased intracranial pressure, or optic nerve strain, potentially leading to vision issues.
- Other Factors: The ligature's tightness, the victim's body position, and pre-existing health conditions (e.g., vascular issues) influence how quickly damage occurs. Brief compression (seconds) is less likely to cause permanent harm, but prolonged or repeated episodes increase the risk.
If blood flow is restored quickly (e.g., within seconds to a minute), vision damage is less likely, though temporary symptoms like blurred vision or floaters may still occur. Any suspicion of a hanging attempt warrants immediate medical evaluation to assess for eye or brain damage, as symptoms may not be immediately apparent.
It seems unlikely that you actually damaged your eyesight attempting partial hanging to me, but it MIGHT be. I guess your only way to be sure is to ask a doctor
