Title: Full Thickness Macular Hole and Internal Limiting Membrane Peeling Study: Randomised Comparison of Macular Hole Surgery With or Without Internal Limiting Membrane Peeling
Brief Summary: A macular hole is a fairly common problem in the retina and is an important cause of loss of central vision. The aim of this study is to determine whether, in patients with a stage 2 or 3 full thickness macular hole (FTMH), peeling a very fine, transparent tissue that covers the surface of the retina, called the internal limiting membrane (ILM) during surgery is superior to non-ILM peeling macular hole surgery. The main outcomes are improvement in vision, achievement of macular hole closure, need for re-operation, health related quality of life (HRQOL) and cost effectiveness.


Options:
A: Inclusion Criteria:

* Presence of focal vitreomacular adhesion (i.e., central vitreal adhesion within 6 mm Optical Coherence Tomography (OCT) field surrounded by elevation of the posterior vitreous cortex) that in the opinion of the Investigator is related to decreased visual function (such as metamorphopsia, decreased visual acuity, or other visual complaint)

Exclusion Criteria:

* Any evidence of proliferative retinopathy (including Proliferative Diabetic Retinopathy (PDR)) or other ischemic retinopathies involving vitreoretinal vascular proliferation) or exudative Age-Related Macular Degeneration (AMD) or retinal vein occlusion in the study eye
* Subjects with any vitreous hemorrhage or any other vitreous opacification which precludes either of the following: visualization of the posterior pole by visual inspection OR adequate assessment of the macula by either OCT and/or fluorescein angiogram in the study eye
* Subjects with macular hole diameter \> 400 µm in the study eye
* Aphakia in the study eye
* High myopia (more than 8D) in study eye (unless prior cataract extraction or refractive surgery that makes refraction assessment unreliable for myopia severity approximation, in which case axial length \>28 mm is an exclusion).
B: Inclusion Criteria:

* Presence of focal vitreomacular adhesion (i.e., central vitreal adhesion within 6mm Optical Coherence Tomography (OCT) field surrounded by elevation of the posterior vitreous cortex) that in the opinion of the Investigator is related to decreased visual function (such as metamorphopsia, decreased visual acuity, or other visual complaint)

Exclusion Criteria:

* Any evidence of proliferative retinopathy (including Proliferative Diabetic Retinopathy (PDR) or other ischemic retinopathies involving vitreoretinal vascular proliferation) or exudative Age-Related Macular Degeneration (AMD) or retinal vein occlusion in the study eye.
* Subjects with any vitreous hemorrhage or any other vitreous opacification which precludes either of the following: visualization of the posterior pole by visual inspection OR adequate assessment of the macula by either OCT and/or fluorescein angiogram in the study eye.
* Subjects with macular hole diameter \> 400 μm in the study eye.
* Aphakia in the study eye.
* High myopia (more than 8D) in study eye (unless prior cataract extraction or refractive surgery that makes refraction assessment unreliable for myopia severity approximation, in which case axial length \>28 mm is an exclusion).
C: Inclusion Criteria:

* Idiopathic macular hele stage 2 or 3.
* Duration of Symptoms ≤ 12 months.
* Visual acuity ≥ 34 ETDRS letters.
* Intraocular pressure ≤ 23 mmHg.
* Informed consent.

Exclusion Criteria:

* Previous macular hole in project eye
* Macular pucker worse than a cellophane macular reflex.
* Previous surgery or disease in the eye affecting retinal function.
* Systemic disease affection vision including diabetes mellitus with level of retinopathy ≥ 14a.
* Amblyopia i project eye.
D: Inclusion Criteria:

Idiopathic FTMH of stage 2-3, Duration of hole ≤18 months, Visual acuity equal to or worse than 20/40 in the study eye.

Exclusion Criteria:

Stage 1 or 4 FTMH, Stage 2-3 FTMH of \> 18 months duration, Visual acuity \>20/40 in study eye, FTMH related to high myopia (\>6 dioptres), FTMH related to trauma, any other causes of decreased vision (ie corneal scarring, age-related macular degeneration, diabetic retinopathy, glaucoma if central and/or paracentral absolute visual field defects present), patient unable to understand English, patient unable to give informed consent.
