Retinal Tear or Detachment
The retina is the light-sensitive tissue lining the back of our eye. The retina converts the light rays into impulses that travel through the optic nerve to our brain, where they are interpreted as the images we see. A healthy, intact retina is key to clear vision. Floaters look like small specks, dots, circles, lines or cobwebs in your field of vision. They originate from a gel like substance that fills the inside of the eyeball behind the lens called vitreous. As we age, our vitreous gel starts to thicken or shrink, forming clumps or strands in it that appear as small, occasional floaters.
A retinal tear or a detached retina is repaired with a surgical procedure.
Risk For Retinal Detachment
- Previous cataract, glaucoma or other eye surgery
- Glaucoma medications that make the pupil small (like pilocarpine)
- Severe eye injury
- Previous retinal detachment in the other eye
- Family history of retinal detachment
- Weak areas in the retina that can be seen by an ophthalmologist during an eye exam

Torn Retina Surgery
Most retinal tears need to be treated by sealing the retina to the back wall of the eye with laser surgery or cryotherapy (a freezing treatment). Both of these procedures create a scar that helps seal the retina to the back of the eye. This prevents fluid from traveling through the tear and under the retina, which usually prevents the retina from detaching. These treatments cause little or no discomfort and can be performed in the office.
Detached Retina Surgery
Almost all patients with retinal detachments must have surgery to place the retina back in its proper position. Otherwise, the retina will lose the ability to function, possibly permanently, and blindness can result. The method for fixing retinal detachment depends on the characteristics of the detachment.
The retina is the light-sensitive tissue lining the back of our eye. The retina converts the light rays into impulses that travel through the optic nerve to our brain, where they are interpreted as the images we see.
Macular hole is when a tear or opening forms in your macula. As the hole forms, things in your central vision will look blurry, wavy or distorted.
Macular pucker (also knows as Epiretinal Membrane or ERM) happens when wrinkles, creases or bulges form on your macula.

It’s hard to explain the magic of suddenly being able to see better than 20/20 vision upon waking up when every morning since you were a kid you had to reach for glasses.
That’s the magic working with Dr. Mahili for Lasik surgery.
I was nervous about getting Lasik initially (lasers in my eyes?!) but heard of the benefits. I totally trusted Dr. Mahili — he never just tried to sell me a procedure, walked me through all angles of it, and only used top of the line equipment.
I’d recommend anyone looking for Lasik to get it here!
"Dr. Malihi is awesome, very professional, compassionate and caring and has the most respect for his patients. He makes everything easy to understand. He was careful to show me the photos of my eyes and what they mean. I really appreciated the time he took to make sure that he provided a thorough exam rather than rushing through a basic exam to get me out the door... and his ability to make the exam enjoyable. Highly recommended :)"
"My wife and I were referred to DR. Malihi by a friend , If you are looking for a best Ophthalmologist in Portland, this is the place. Extremely warm and welcoming environment. DR. Malihi takes his time with you, explains the issues and treatment so you really understand. The best part, his treatments are done with care highly recommended."
"The staff and Doctor are very kind and knowledgeable. My daughter had to have her eyes dilated due to a possible illness. We were both very scared our Doctor made us feel like we had known him for years. He was able to find a problem and explain to us and show us without frightening us what the situation was. I recommend this to anyone that needs their eyes checked."
"I am very pleased with the way that he fully checked and considered all the aspects and especially his excellent explanation and communicating with me, I appreciate him for his his treatment and recommend him to all."
