What is Epiretinal Membrane?

Epiretinal membrane is a proliferation of glial cells and collagen on the inner surface of the retina at the macula.

The idiopathic form is the commonest, typically developing after posterior vitreous detachment in patients over 50.

Secondary ERMs follow retinal tear repair, cryotherapy, uveitis, vascular disease, or intraocular surgery.

OCT demonstrates the membrane and quantifies retinal thickness, traction, and macular architecture to guide management.

Symptoms

Metamorphopsia (straight lines appear distorted or wavy)

Decreased visual acuity

Macropsia or micropsia (objects appear larger or smaller)

Blurred vision

Monocular diplopia (double vision in one eye)

Risk Factors

Age over 50 years

Posterior vitreous detachment

Previous retinal tear or detachment surgery

History of uveitis

Intraocular inflammation or vascular disease

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

If straight lines appear bent or wavy
If vision declines gradually
If objects look different sizes in one eye

Treatment Methods

Observation with regular OCT monitoring for mild cases

Pars plana vitrectomy with membrane peeling

Internal limiting membrane (ILM) peeling to reduce recurrence

Postoperative positioning (usually not strictly face-down)

Visual rehabilitation and low-vision aids if needed

Branch retinal vein occlusion (BRVO) is a vascular eye disease caused by blockage of one of the retinal vein branches, leading to bleeding, oedema, and ischaemia in the affected territory. Macular oedema is the main cause of vision loss and is treated with anti-VEGF injections and laser.

Episcleritis

Göz Hastalıkları

Episcleritis is inflammation of the episcleral tissue overlying the sclera. It causes redness and mild discomfort in the eye and is usually a benign and self-limiting condition.

Scleritis

Göz Hastalıkları

Scleritis is a deep inflammation of the white layer of the eye. It presents with severe eye pain and can lead to vision loss if untreated. It is often associated with autoimmune diseases.

Acquired Eyelid Drooping (Acquired Ptosis)

Göz Hastalıkları

Acquired ptosis is the abnormal drooping of the upper eyelid due to muscle weakness, nerve damage, or aging. It can restrict the visual field.

Ocular Hypertension

Göz Hastalıkları

Ocular hypertension is elevated intraocular pressure (IOP) above 21 mmHg without glaucomatous optic nerve damage or visual field defects. It is the most significant risk factor for primary open-angle glaucoma and requires regular monitoring.

Dacryoadenitis

Göz Hastalıkları

Dacryoadenitis is inflammation of the lacrimal gland located in the outer portion of the upper eyelid, caused by infection or autoimmune conditions.

Central Corneal Ulcer

Göz Hastalıkları

A central corneal ulcer is an infectious ulcer that develops in the central region of the cornea. It is a serious condition requiring urgent treatment and can lead to vision loss.

Vitreous Haemorrhage

Göz Hastalıkları

Vitreous haemorrhage is bleeding into the vitreous cavity from retinal vessels, causing sudden floaters and vision loss. Proliferative diabetic retinopathy is the most common cause; determining the underlying cause is critical for management.
