Macular Hole
Overview
Macular hole is a
problem that affects the very central portion of the
retina.
It happens for a variety of reasons such as: eye injuries,
certain diseases, and
inflammation inside the eye. However, the most common cause is
related to the normal aging process.
The
vitreous
gel inside the eye is firmly attached to the
macula.
With age, the vitreous becomes thinner and separates from the
retina. Sometimes this creates traction on the macula, causing
a hole to form.
Macular holes often
begin gradually and affect central vision depending on the severity
and extent of the problem. Partial holes only affect part of
the macular layers, causing wavy, distorted, blurred vision.
Patients with full-thickness macular holes experience a complete
loss of central vision.
Signs and Symptoms
The severity of the
symptoms is dependent on whether the hole is partial or
full-thickness.
Detection and Diagnosis
Visual acuity testing,
Amsler grid, and
ophthalmoscopy are all
performed to evaluate the macula's health and function. The
retina doctor may also order
photographs of the macula prior to performing surgery to repair
the hole.
Treatment
Some macular holes
seal spontaneously and require no treatment. In many cases,
surgery is necessary to close the hole and restore useful vision.
Macular holes are
repaired with surgery. During the operation, the surgeon first
gently removes the vitreous gel with a procedure called vitrectomy.
This eliminates any traction on the macula. A gas bubble is
injected in the eye to place gentle pressure on the macula and help
the hole to seal. In many cases, patients enjoy functional
vision after the bubble has dissipated and the eye has healed.
