![]() ![]() Another potential treatment for some patients with macular holes is the injection of ocriplasmin (Jetrea®) into the vitreous. Potential complications of the procedure include cataract formation, retinal detachment, infection, glaucoma, bleeding, and re-opening or persistence of the macular hole (less than 10% of cases). Vitrectomy has a success rate of over 90%, with patients regaining some or most of their lost vision. This will allow the bubble to gradually dissolve and be replaced by natural eye fluids. ![]() The patient may be asked to maintain a face-down position for several days, and in some cases up to 2 weeks, depending on the characteristics of the macular hole. In this surgical procedure, the vitreous gel is removed to stop it from pulling on the retina, and most commonly a gas bubble is placed in the eye to gently hold the edges of the macular hole closed until it heals. Vitrectomy is the most common treatment for macular holes. © the American Society of Retina Specialists.

Vitreous traction: the vitreous is the “gel” that fills up the inside of the eye.Several conditions can increase the risk of macular hole formation, including: ![]() If a macular hole develops in one eye, there is a 5% to 15% risk of one developing in the other eye. For this reason, there is currently no effective way to prevent their formation and development. The vast majority of cases develop spontaneously without an obvious cause. Macular hole commonly affects people over the age of 55 and most often occurs in women. The degree to which vision is affected will depend on the size and location of the macular hole, as well as the stage of its development. Distortion (straight lines appearing wavy).The most common symptom of macular hole is a gradual decline in the central (straight-ahead) vision of the affected eye. When a full-thickness defect develops in the macula, the condition is referred to as macular hole. If you would like more information about what causes a macular hole, please contact Associated Retina Consultants at 60 or website to schedule an appointment with our doctors.The macula is a small area in the center of the retina where light is sharply focused to produce the detailed color vision needed for tasks such as reading and driving. Macular pucker: formation of scar tissue over the macula that can warp and contract, causing wrinkling of the retina.The cause of a macular hole is usually associated with aging and usually occurs in people over the age of 60. In either case, the fluid that has replaced the shrunken vitreous can then seep through the hole onto the macula, blurring and distorting central vision. This increases tension on the retina and can lead to a macular hole. Also, once the vitreous has pulled away from the surface of the retina, some of the fibers can remain on the retinal surface and can contract. However, if the vitreous is firmly attached to the retina when it pulls away, it can tear the retina and create a macular hole. Some patients may experience a small increase in floaters, which are little “cobwebs” or specks that seem to float about in your field of vision. This is normal and in most cases, there are no adverse effects. Natural fluids fill the area where the vitreous has contracted. As we age, the vitreous slowly shrinks and pulls away from the retinal surface. The vitreous contains millions of fine fibers that are attached to the surface of the retina. Most of the eye’s interior is filled with vitreous, a gel-like substance that fills about 80% of the eye and helps it maintain a round shape. A macular hole can cause blurred and distorted central vision. The macula provides the sharp, central vision we need for reading, driving and seeing fine detail. A macular hole is a small break in the macula, located in the center of the eye’s light-sensitive tissue called the retina. ![]()
