Brief Answer:
Retinal detachment.

Detailed Answer:

Hi,
Thanks for choosing HealthcareMagic for your query
It most likely due to retinal detachement.Retinal detachment separates the retinal cells from the layer of blood vessels that provides oxygen and nourishment.In long term if left untreated may cause loss of vision in affected eye.

Retinal imaging is a recent technological advancement in eyecare. It enables your optometrist to capture a digital image of the retina, blood vessels and optic nerve located at the back of your eyes.The sudden appearance of floaters and flashes and reduced vision is usually presenting symptom of retinal detachment.

As per your query
I an occur as a result of:
A sagging vitreous-the gel ike material that fills the inside of your eye
Eye injury
Advanced diabetes
Old age- Eye floaters most commonly occur as a result of age-related changes in the vitreous.Over time, the vitreous partially liquefies — a process that causes it to pull away from the eyeball's interior surface. As the vitreous shrinks and sags, it clumps and gets stringy. Bits of this debris block some of the light passing through the eye, casting tiny shadows on your retina. Retinal tears can occur when a sagging vitreous tugs on the retina with enough force to tear it.Retinal tear may lead to retinal detachment.

Detailed Answer:
Hi again,

1)The treatment of optic nerve gliomas is controversial. No treatment may be required in patients with no growth, good vision & no cosmetic deformity. In case of malignant gliomas (glioblastomas) despite treatment, including high-dose radiotherapy and chemotherapy, these tumors usually result in death within 6-12 months.
Initially go for a MRI to know nature and extent of tumour.

2)Retinal detachement-
Two most important surgeries are-
a)Laser surgery (photocoagulation). The surgeon directs a laser beam into the eye through the pupil. The laser makes burns around the retinal tear, creating scarring that usually "welds" the retina to underlying tissue.


b)Freezing (cryopexy). After giving you a local anesthetic to numb your eye, the surgeon applies a freezing probe to the outer surface of the eye directly over the tear. The freezing causes a scar that helps secure the retina to the eye wall.
