Introduction
A macular hole typically refers to a tissue defect forming an opening from the inner limiting membrane of the retina through to the photoreceptor layer in the macular area. Idiopathic macular holes, which have no known cause, are relatively common and usually occur in healthy women over the age of 50, with a higher incidence of unilateral involvement. Since the macula is located at the center of the retina, it is the region most sensitive to vision.
After macular hole surgery, the gas bubble typically disappears within about one week.
A macular hole usually refers to a tissue defect forming an opening from the internal limiting membrane of the retina through to the photoreceptor layer in the macular area. Idiopathic macular holes of unknown cause are more common and typically occur in healthy women over the age of 50, with a higher incidence of unilateral involvement. Since the macula is located at the center of the retina and represents the most visually sensitive area, the presence of a macular hole can lead to blurred vision and visual distortion. These symptoms are often only noticed when the unaffected eye is covered. Most macular holes can be cured surgically. Macular hole surgery usually involves injecting air into the vitreous cavity or filling it with silicone oil. As the gas is absorbed, patients may notice bubbles or droplets in their vision, which typically resolve within approximately one week.
Patients should pay attention to postoperative body posture and head positioning. It is generally recommended to maintain a prone position to ensure that the silicone oil or gas remains positioned over the macular hole, thereby promoting healing. It is also important to maintain a positive mindset and avoid emotional stress.
