Macular Surgery
Macular surgery under the care of Dr. Nishant Taneja at the Indian Eye Institute and Laser Center in Tirana. These procedures are used to treat epiretinal membranes, macular holes, and submacular hemorrhage, with the aim of preserving and improving central vision.
What Is Macular Surgery?
The macula is the central and most sensitive part of the retina, responsible for seeing fine details, reading, and recognizing faces.
Macular surgery is used to treat epiretinal membranes, macular holes, and certain cases of submacular hemorrhage. Depending on the condition, the procedure may involve vitrectomy, removal of thin membranes from the retina, subretinal injection, and placement of a gas bubble.
Vitrectomy is performed through micro-incisions and involves removing the vitreous gel to provide safe access to the macula. Dr. Nishant Taneja uses micro-instrument technology to reduce surgical trauma and improve comfort after the procedure.
Dr. Taneja regularly performs procedures for epiretinal membranes and macular holes, has experience with subretinal injections, and trains ophthalmologists and young retinal surgeons in macular surgery.

Moments with Our Patients
What symptoms may indicate a macular problem?
Macular diseases primarily affect central vision. Depending on the cause, symptoms may develop gradually or appear suddenly.
Blurred Central Vision
Distorted Lines
Difficulty Reading
Loss of Depth Perception
Spot in the Center of Vision
Sudden Vision Loss
Treatments Macular Surgical Treatments
Treatment is selected based on the condition, the extent of damage, the duration of symptoms, and the overall health of the retina.
Epiretinal Membrane Removal
Epiretinal membranes are common and affect around 5% of people. Most do not cause significant problems, but in some patients they can cause blurred vision, visual distortion, and loss of depth perception.
Patients with troublesome vision changes may be treated with vitrectomy and membrane removal. After the vitreous is removed, very fine forceps are used to peel the epiretinal membrane from the surface of the retina.
More than 90% of patients experience improved vision after epiretinal membrane removal surgery. The extent and speed of improvement vary from patient to patient.
Macular Hole Surgery
A macular hole develops when traction on the central retina creates an opening in its most sensitive area. This can cause deterioration and distortion of central vision.
Natural closure of a macular hole is rare. Surgery involves vitrectomy, removal of the internal limiting membrane (ILM), and the injection of a gas bubble into the eye.
A vital dye, such as ILM Blue, may be used to identify the ILM, which is then removed with very fine forceps. More than 95% of macular holes close after surgery.
The gas bubble is usually absorbed over a period of approximately two weeks, although a longer-acting gas may be used in certain cases.
Subretinal Injections
A submacular hemorrhage is an accumulation of blood beneath the macula and can cause severe vision loss. It is most commonly caused by macular degeneration or retinal arterial macroaneurysms.
Treatment may range from careful monitoring to the subretinal injection of tissue plasminogen activator (tPA), which is used to help break down the blood clot.
The subretinal injection is performed after vitrectomy. The space beneath the retina is accessed using a small, soft-tipped cannula, and a gas bubble may be placed in the eye at the end of the procedure.
The need for postoperative positioning is determined on an individual basis. The prognosis depends on the cause, size, and duration of the hemorrhage, as well as the condition of the macula.
Benefits of Macular Surgery
The surgery aims to reduce traction on the macula, correct anatomical damage, and protect central vision.

Epiretinal Membrane Removal
The procedure aims to remove the membrane that wrinkles or pulls on the surface of the macula.
- Micro-incision vitrectomy
- Removal of the vitreous gel
- Removal of the epiretinal membrane
- Use of microsurgical forceps
Macular Hole Surgery
The procedure aims to relieve traction on the macula and create the conditions needed for the hole to close.
- Vitrectomy
- Removal of the ILM
- Use of a vital dye
- Placement of a gas bubble
Subretinal Injection
This treatment may be used in selected cases of submacular hemorrhage to help displace blood away from the center of the macula.
- Vitrectomy
- Subretinal injection of tPA
- Use of a fine cannula
- Placement of a gas bubble
What to Expect
01. Macular Examination
During the examination, visual acuity is assessed, intraocular pressure is measured, and the retina is examined after the pupils have been dilated.
Macular OCT is used to assess the epiretinal membrane, retinal traction, the size of the macular hole, or other changes in the central retinal structure.
In cases of submacular hemorrhage, the size, duration, and cause of the bleeding are assessed. The prognosis and treatment options are discussed after a comprehensive examination.
02. Procedure
Macular surgery is usually performed under local anesthesia with sedation. The patient remains awake, but the eye is numbed to minimize discomfort during the procedure.
Vitrectomy is performed through micro-incisions. The vitreous gel is removed to provide access to the macula, and microinstruments are used to remove the epiretinal membrane or ILM.
In macular hole surgery, a vital dye is used to visualize the ILM, and a gas bubble is placed in the eye at the end of the procedure.
In cases of submacular hemorrhage, tPA may be injected beneath the retina with a fine cannula following vitrectomy. At the end of the procedure, gas may be placed in the eye to help displace the blood.
03. Recovery and Follow-Up
Patients usually stay in the hospital overnight after the procedure and may be discharged the following morning.
If gas is placed in the eye, vision will remain blurred until the bubble shrinks and is absorbed. The gas may remain in the eye for around two weeks, although the duration depends on the type used.
Postoperative positioning is determined on a case-by-case basis. For most patients with a macular hole, Dr. Taneja can offer recovery without the need for mandatory positioning.
Patients with gas in the eye must not travel by air until Dr. Taneja confirms that the bubble has been fully absorbed.
Eye drops should be used as directed. Severe pain, worsening redness, or a sudden decrease in vision requires immediate contact with the clinic.

Frequently Asked Questions
Surgery is usually performed under local anesthesia with sedation, so the patient should not feel any pain. During the procedure, they may perceive light, movement, or slight pressure.
Not in every case. The need for positioning depends on the condition, the size of the hole, and the type of gas used. For most patients with a macular hole, Dr. Taneja can offer treatment without the need for mandatory positioning.
No. Air travel must be avoided until the gas bubble has been fully absorbed and Dr. Taneja confirms that it is safe to fly.
Improvement is usually gradual and depends on the condition, the duration of the damage, and the state of the macula. If gas was used, vision will remain blurred until the bubble shrinks.
