Macular hole

What it is

A macular hole is a defect or layered separation at the macula (the retinal region of sharpest central vision). Public education often means a full-thickness macular hole (FTMH)—a full-thickness break in that retina. There are also lamellar holes and pseudo-holes from epiretinal-membrane contraction (looks like a hole on the surface, but OCT shows it is not full-thickness). The three are managed differently; do not self-label.

Common symptoms: blurred central vision and reading difficulty; bent straight lines or image distortion (metamorphopsia); a fixed central scotoma or a sense that “a piece is missing.”

Most idiopathic FTMHs relate to vitreous traction on the macula / vitreomacular interface change (traction during age-related posterior vitreous detachment is the classic pathologic concept). High myopia, trauma, and other retinal disease can also be associated—which category applies is for a doctor to judge.

Formation and staging (soft concepts, not a self-test)

In the public literature, Gass and others described early stages and pathogenesis of idiopathic macular hole from clinical / biomicroscopic observation, later reappraised staging; modern practice often uses OCT and International Vitreomacular Traction Study (IVTS)–style imaging classes to aid communication (vitreomacular adhesion / traction, FTMH size, and so on). This page does not teach you to stage yourself; stage language is only vocabulary for reading a doctor’s report.

Prevalence (named studies · not personal risk)

• Beaver Dam Eye Study (SD-OCT, Meuer et al., 2015): among gradable scans in roughly ages 63–102 in that round, estimated FTMH prevalence was about 0.4%; the same study also reported lamellar holes, epiretinal membranes, and other interface findings. These are results for that study, method, and age band—not your personal risk, and not a clinic comparison.
• FTMH is relatively uncommon in population studies; after OCT became widespread, “interface abnormalities” are seen more often—that does not mean everyone progresses to an FTMH.

Natural history (education)

• Eye Disease Case-Control Study (Chew et al., 1999): in eyes that already had a macular hole, some holes enlarged and some vision worsened in follow-up; the rate of later new holes in fellow eyes that were initially unaffected was relatively low in that study’s follow-up strata. Not a prediction of whether you personally will worsen.
• Vitrectomy for Macular Hole Study (Kim et al., 1995): many stage-2 FTMHs in the observation arm progressed to larger stages in follow-up—supporting the educational point that FTMHs are often not stably static, still not a personal timetable.
• Spontaneous closure can occur, but published series do not make it a reliable expectation for most FTMHs; do not assume “it will heal by itself.”

When to seek care

Prompt (usually same-day) ophthalmic assessment: new clear drop in central vision, metamorphopsia, or a central scotoma.

• A&E / 999 (and see the retinal detachment topic): a curtain over the visual field, large field loss, sudden blindness; severe pain with vomiting, penetrating injury, chemical splash, and so on (see the urgent page).
• New flashes or a clear increase in floaters without a curtain / without sudden blindness: seek dilated fundus exam as soon as possible (ideally same day)—the same path as the retinal detachment topic; the macular-hole topic does not replace peripheral tear / detachment checks.

Tests a doctor may discuss (concepts)

• Vision testing and an Amsler grid (supportive; not a substitute for examination)
• Dilated fundus examination
• Optical coherence tomography (OCT): distinguish FTMH / lamellar / pseudo-hole, measure minimum aperture, assess vitreomacular traction, and whether an epiretinal membrane is present—the core modern tool for diagnosis and shared understanding
• Fundus photography or other imaging when needed (doctor’s decision)

Treatment classes (not a prescription · not a guarantee)

For a symptomatic FTMH, a doctor may discuss pars plana vitrectomy to relieve traction, often with internal limiting membrane–related steps, and intraocular gas tamponade to encourage anatomic closure; posture (e.g. face-down) may be discussed in some cases—how many days and whether it is required can only be individualised by a doctor; this page is not a recipe.

• Kelly / Wendel early series (1991, 1993): pioneering / series experience of vitreous surgery for idiopathic macular hole—foundational technique direction, not a modern single success-rate benchmark, and not your prognosis.
• Multicentre randomised trial (Freeman et al. / Vitrectomy for Macular Hole Study, 1997): versus observation, the surgery arm had higher anatomic closure rates and signals of visual benefit, with adverse events such as cataract—results under trial conditions, not clinic advertising.
• Moorfields randomised trial (Ezra / Gregor et al., 2004): compared natural history, vitrectomy, and vitrectomy plus autologous serum—educationally stresses surgery’s role versus observation, not a guarantee.
• Larger holes may involve discussion of technique variants such as inverted ILM flaps (e.g. methods reported by Michalewska et al.)—options education, not a ranking of clinic technique.

• Whether closure occurs varies with duration, hole size, and individual factors, and is still not guaranteed; shorter duration is often more favourable—not “earlier always means full recovery.”
• In phakic eyes, cataract often accelerates after surgery (qualitative education; details in the retinal detachment topic’s gas / complication concepts).
• While expansile gas remains in the eye, do not fly and avoid nitrous oxide anaesthesia; blurred vision before the bubble absorbs is expected—see the retinal detachment topic.
