Weak veins: Subconjunctival hemorrhage is due to leakage from fragile veins in the conjunctiva. This can be caused by rubbing the eye, sneezing, straining and light trauma. Frequently no cause is identified. Almost always it is benign and will absorb with no consequences. See your ophthalmologist if it is recurrent. ...Read moreSee 2 more doctor answers
Yes: Most common procedure to repair a retinal detachment resulting from a macular hole is a vitrectomy (remove the fluids from the back of the eyeball), replace it with a gas, and position the patient face down for some period of time (sometimes weeks) to allow the hole to close and the detachment to resolve. Most macular holes do not cause a detached retina, but many require a similar operation. ...Read moreSee 1 more doctor answer
Yes: The vitreous jelly that fills the eye and attaches to the back wall of the inside of the eye (the retina) will detach from the retina with age (posterior vitreous detachment). At that time or days/weeks later a retinal tear or detachment may or may not occur as well. The latter conditions require urgent treatment before blindness ensues. A vitreous detachment is not treated. ...Read moreSee 2 more doctor answers

Micropsia: Yes, it can if the macular pucker is severe enough. Micropsia is a condition in which objects are perceived to be smaller than they actually are. Micropsia can be caused by optical factors (such as wearing glasses), by distortion of images in the eye (such as optically, via swelling of the cornea or from changes in the shape of the retina such as from retinal edema,macular degeneration, and more ...Read more
Many functions: The RPE is a layer underneath the retina that serves many roles. Its many functions include light absorption, epithelial transport, spatial ion buffering, visual cycle, phagocytosis, secretion and immune modulation. Without it, the retina degenerates as in various diseases including AMD. ...Read more
Eye parts: The cornea is the window at the front of the eye which focus light and allows it to enter the eye. Contact lenses rest on the cornea. The macular is the central retinal area of sharper vision and the fovea is the very center of the macula with the sharpest of all vision. ...Read moreSee 2 more doctor answers
Detached Retina: It is actually a tractional retinal detachment. When diabetes causes the retinal blood vessels to die, the retina grows new blood vessels that are disorganized and of poor quality. They grow into the gel that fills the eye called the vitreous. This causes the vitreous to contract and pulls the retina off the back to the eye. That is a tractional retinal detachment. It often needs surgery. ...Read moreSee 2 more doctor answers
Is optos ultra-wide field retinal imaging more efficient than indirect ophthalmoscopy to see large details of the retina?
Efficiency-accuracy: Efficiency, speed, ease of use are attributes of optos, but detailed, high magnification ; dynamic indirect ophthalmoscopy by the eye md is better for careful discriminative diagnoses. Sorry, i don't want to be replaced (yet) by a camera! i've never been able to replace my careful examination of the retina with indirect ophthalmoscopy by an image, except by sd-oct which is excellent. ...Read more
Is every retinal tear/detachment caught in indirect opthalmoscope test,what are the chances of a doctor missing a tear/detachment by an indirect optha?
Depends: On the skill of the doctor. Ophthalmologists are trained to identify these problems. Optometrists, less so. Retinal specialists are the most skilled with this. ...Read more
