Third Nerve Palsy: Double Vision, Droop, When the Pupil Makes It Urgent
Third nerve palsy double vision with a droopy lid. A dilated pupil can mean aneurysm — emergency care, not a blog slot. ReliveCure evaluates the non-emergency forks the same day.
Third nerve palsy double vision is a droopy lid, an eye that will not move up, down or in, and often a pupil that will not constrict. People search it after sudden diplopia, a lid that dropped overnight, or a photograph where one pupil looks larger. The fork that matters is the pupil. A dilated pupil with a third-nerve picture can be an aneurysm. That is emergency care, not a ReliveCure theatre date and not a “book nerve palsy” campaign.
This page exists so a worried family does not land on a LASIK carousel. ReliveCure evaluates double vision that is not that emergency picture in Gurugram, Hyderabad, Pune or Mumbai. If the pupil is large, the headache is explosive, or consciousness is wrong, go to emergency care now. Then call +91 96500 23161 so we know you are moving.
What the third nerve actually does
Cranial nerve III lifts the lid, moves the eye in several directions, and constricts the pupil. When it fails, the lid droops, the eye sits “down and out,” and diplopia is worst when you look at something close or up. People close one eye to drive. That is not a glasses update.
Squint surgery for a childhood turn is a different clock. New adult double vision is not “they will grow out of it.” Thyroid eye disease can also double, usually with stare and lid retraction, not an isolated III palsy.
A sixth-nerve stretch from raised intracranial pressure sits on papilledema and IIH. That is both discs plus diplopia, not a classic III.
The pupil rule (read this twice)
III + dilated pupil → treat as aneurysm until imaging says otherwise. Get urgent care. We will not book that as a product from a blog. We will not delay you for a free evaluation slot while a vessel is the worry.
III with a spared pupil, especially in an older person with diabetes or vascular risk, is more often ischaemic. It still needs a same-day look. It is not permission to wait a week.
We do not print imaging protocols or drug doses here. Those belong to the team who sees you.
What ReliveCure does when this is not the aneurysm fork
You come in. We map the lid, the pupil, the versions, and blood pressure. We write whether this is an isolated III, a pupil-involving emergency already sent onward, or a different diplopia (fourth, sixth, decompensated childhood squint, orbit). We take you through the plan in Gurugram, Hyderabad, Pune or Mumbai.
India private-market bands (not ReliveCure quotes):
| Item | Range | Typical cover |
|---|---|---|
| Neuro-ophthalmic assessment | ₹2,000–6,000 | OPD — usually not reimbursed |
| MRI brain and orbit | ₹6,000–20,000 | More often paid if admitted |
| Botulinum for nerve-palsy diplopia | ₹15,000–35,000 | Usually covered when diplopia is documented |
| Prism glasses | ₹3,000–15,000 | Not covered — optical appliance |
Cover: usually / typically. Cashless option also available. May not be as well — depends on the personal case. Parent map: eye surgery insurance in India. Prisms are appliances, like the low vision rule — useful, rarely a claim.
Botulinum can quiet diplopia while the nerve recovers. It is not a cosmetic lid product. Muscle surgery, if it is ever honest, waits until the measurements stop moving. We will not sell a wedding-date alignment.
Call today versus emergency department
Emergency department now: III + dilated pupil, worst headache of life, dropping consciousness, trauma. Do not use this form.
Same-day ReliveCure: new double vision, a droopy lid, pupil not dilated, you can still come in. +91 96500 23161.
Not this page: childhood squint you have had for years, or thyroid stare without a palsy. Use those URLs.
