The retinal macular hole is a full - thickness defect originates in the macula. It affects less than 1% of the population, predominating mainly in the population between 50 and 80 years, especially in women.
The specialist ophthalmologists find that this pathology occurs due to the tensile forces associated with the perifoveal vitreous detachment.
Symptoms of macular hole
The main symptoms presented by this condition are:
- Decreased visual acuity varying degrees: Depending on the size of the hole, the location thereof with respect to the size foveola and neurosensory retinal detachment associated.
- Central scotoma: feeling spot in the field setting.
- Metamorfopsia: deformation of straight lines and objects in general.
The diagnosis of macular hole is performed by scanning biomicrocópica assisted lenses exploration precorneal. Currently, the test is completed more useful optical coherence tomography (OCT). To quantify accurately the details related to the hole.
Macular hole: Treatment
In some cases early stages, you must perform a strict control because spontaneous closure may occur in cases of macular hole stage 1.
Usually, the main treatment for this condition is surgery. It is to perform a vitrectomy with complete removal of the central vitreous, the posterior hyaloid and all epiretinal tissues, including internal limiting membrane of the retina. Once the vitrectomy, internal tamponade with gas and positioning of the head in position prone position is performed.
