Can Coughing Cause Retinal Detachment
The retina is the light sensitive layer in the back of the eye that transmits images to the brain via the optic nerves to create vision. If a hole or tear develops in the retina, eye fluids can separate the retina from underlying layer (choroid) . The most common cause of retinal holes or tears is traction from the vitreous, the clear gel that fils the inside of ...Read more
Yes: It sounds as if you have had a posterior vitreous detachment. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". This also can tear blood vessel. You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. ...Read moreSee 1 more doctor answer
Not easily: Retinal detachment is a consequence of the susceptibility of the eye and underlying disease. High myopes and diabetics are at risk and trauma and eye surgery are commonly involved. Many however, are spontaneous with no apparent underpinnings. Good diabetic control helps; avoidance of trauma can help. Best however is to recognize the symptoms and seek help when it is likely. ...Read moreSee 1 more doctor answer
Yes: The retina of a myopic person tends to be thinner and thus more easily torn or detached. Myopic eyes tend to have a higher chance of retinal pathology, like lattice degeneration or atrophic retinal holes, that also put them at risk. So myopia is really a risk factor rather than a cause. ...Read moreSee 1 more doctor answer
Age: The vitreous jelly changes as we age and it pulls away from the back of the eye (retina) - a posterior vitreous detachment. During this process, if the jelly pulls hard enough on the retina (especially in a thin or weak area) it can tear the retina which can subsequently detach. Other risk factors include myopia, cataract surgery, head/eye trauma, family history, lattice degeneration, etc. ...Read more
Hole in Retina: An rd is usually caused by a hole or tear in the retina or from membranes pulling on the retina. When the retinal layer peels away from the eye wall (like wall paper), it is detached and vision is lost. Symptoms of an rd are painless vision loss, flashing lights, and floaters. You should immediately see an eye md if you have these symptoms. ...Read moreSee 1 more doctor answer
Possibly: Vomiting increases the venous pressure in the head and eyes as well. If there is some weakness of the vessels, they can break open and leak blood. When the blood disperses in the vitreous, it can cause the sensation of floaters. Since these symptoms cross over with retinal detachment, this should be evaluated by a retinal specialist. ...Read more
Serious!: Sudden vision loss can have many causes, including but not limited to retinal detachment. Until proven otherwise, sudden vision loss is very serious, and should be evaluated urgently. In some cases, usually in older individuals, there is also the risk of also loosing vision in the fellow eye, making this symptom all the more urgent with increasing age. ...Read moreSee 1 more doctor answer
Vitreous detachment: It sounds as if you have had a posterior vitreous detachment. This is a situation where the vitreous(jelly) of the eye detaches (not a retinal detachment), it then "crumples" up leaving dots, spots, strands of blurry vitreous; i.e. The "floater". You should have an exam to ensure the incident did not tear the retina, which could lead to a retinal detachment. Wait one year then consider surgery. ...Read moreSee 1 more doctor answer
Can a lattice degeneration by itself (and not associated with any tear or hole) cause or worsen eye floaters?
Lattice degeneration: Hi. Lattice degeneration is not due to the floaters. Rather, lattice occurs in areas where the retina and vitreous come together "more strongly" than other areas. The retina in these areas can be thinner, sometimes with holes, tears, or even retinal detachment. Increase in floaters or flashes means that the vitreous in your eye is changing; may be tugging on the retina. See an ophthalmologist ...Read moreSee 1 more doctor answer
Very many things: There are probably hundreds of injuries and diseases that may cause blindness. Macular degeneration affects 10% of people over 80. Glaucoma risk increases with age. Cataracts can cause blindness if not treated. There are dozens of other neurologic, degenerative, hereditary, infectious, and traumatic causes of blindness, far too many to list here. ...Read more
The cough reflex is a protective mechanism that uses muscles in your throat and chest to expel mucous and saliva that may contain pathogens that would otherwise possibly be inhaled via aerosol or to expel pathogens infecting the throat and respiratory system. Cough benefits the host by reducing load and benefits the pathogen which may then spread via aerosol. ...Read more
