Question 1

what are the common causes of sudden loss of vision in the lower half of one eye?

Accepted Answer

Vascular, detachment: Loss of vision horizontally and only in one eye suddenly usually means a stroke of the eye where one branch of the retinal vessels is blocked.  Due to the vascular anatomy this makes a horizontal line.  Occasionally a superior or inferior retinal detachment can cause similar vision loss but this is usually slower and progressive.

Question 2

what can cause sudden loss of vision in the lower half of one eye?

Accepted Answer

Decreased blood flow: Your very precise description is consistent with interruption of blood flow in a branch of the retinal artery on one side.  This needs attention, as a stroke risk would be present.  Unlikely that this represents migraine.  See an ophtalmologist asap.

Question 3

what causes loss of vision in lower half of right eye please?

Accepted Answer

: If this is focal and inferior, would ponder a retinal lesion perhaps due retinal artery but also wonder about glaucoma (Bjerrum scotoma).  See an ophthalmologist ASAP. Neurologist might be needed here also

Question 4

what might be the cause of temporary loss of vision in one eye? i had no vision in my left eye; i only saw black. within 5 minutes it was better.

Accepted Answer

Loss of vision: This may be a serious symptom and should be reported to your physician.  You should get an appointment to be checked up.

Question 5

i have loss of vision in one eye, several times a month.  is it caused by a temporary blockage like a blood clot?

Accepted Answer

Could be a TIA: A temporary loss of vision in one eye can be a sign of a TIA also known as a transient ischemic attack. It can be caused by small blood clots (emboli) that break off from either the heart or carotid artery in the neck. See your primary care provider for evaluation that may include ultrasound studies.

Question 6

dr said swollen left eye optical nerve caused loss of vision in my lower left eye. after 5 months the swelling is gone and he says the damage is perma?

Accepted Answer

Time will tell: Nerve damage often is permanent , so even if the swelling is gone it certainly is possible that loss of vision will be permanent. Hopefully, the damage was mild, and you will gain some vision back, but the longer the vision problems the more likely it is permanent.

Question 7

what would cause  sudden  loss of vision in the right upper corner of the eye?

Accepted Answer

Many things: This problem can only be solved by seeing your doctor and being evaluated face-to-face.  After a thorough examination, your doctor should be able to tell you what's wrong and what to do about it.

Question 8

after 3 days of metronidazole antibiotic course i gained loss of vision in one eye. i can describe it as loss of clarity and color and most importantly contrast but i can still see. it's been 4 months and it did not improve.what now?

Accepted Answer

: Go to drugs.com and enter exactly your meds and see if this is a known side effect or it other meds interact to cause this.

Question 9

should i be concerned about severe loss of vision in one eye (over one year), recently drooping eyelid, sleep issues, and pineal gland cyst?

Accepted Answer

Yes: Please see a doctor today!  any loss of vision with other symptoms such as eyelid droop should be evaluated quickly.  Please seek help from your doctor and good luck!

Question 10

why did i have loss of vision and grey field in one eye briefly? under stress then.

Accepted Answer

Many reasons: Its difficult to answer these kind of questions, not knowing some information.  However, it could be migrains, tia, amaurosis fugax, visual changes induced by exercise, drop in blood pressure, etc.   Stress in itself wouldn't cause a brief loss of vision, although it has been associated with central serous chorioretinopathy, which can cause a prolonged distortion of vision.
