Vitrectomy Surgery in Nigeria

Introduction 
Vitrectomy is a crucial surgical procedure utilized to correct various vitreoretinal pathologies, finally recovering vision and preventing blindness. With its introduction in 1970, constant innovations in technology, instrumentation, and surgical methods have made vitrectomy one of the most successful retinal disorder treatments in the world. The procedure has revolutionized visual outcomes for patients with conditions such as retinal detachment, diabetic retinopathy, and vitreous hemorrhage. However, in spite of the universal acceptance of vitrectomy as a routine treatment in the majority of developed countries, it is not available in some low-resource areas, e.g., Nigeria.

One of the greatest obstacles to the availability of vitrectomy in Nigeria is the very high cost of the operation. The expenses include specialized surgical equipment, maintenance of high-technology operating theatres, and the need for extended training of ophthalmologists. It is difficult for most eye centers and hospitals to acquire the necessary resources, thus the inability of patients to receive treatment promptly. Therefore, patients with conditions that require vitrectomy often wait or are referred to distant healthcare facilities, which can help worsen vision loss or blindness. This shortage of skilled professionals and essential surgical devices also adds to the burden of preventable visual impairment in the country.

Despite these challenges, vitrectomy remains a critical tool in ophthalmic care, bringing life-changing benefits to patients suffering from severe retinal diseases. Efforts are being made to expand access to vitrectomy in Nigeria through specialized training initiatives, collaborations with international eye care organizations, and the adoption of cost-effective surgical techniques. The growing awareness of vitreoretinal afflictions and the private sector along with the government stepping forward can place the service of these life-saving procedures within reach. Trained ophthalmologists in increasing numbers and increased hospital facilities attaining the required equipment is certain to provide wider access to the surgery of vitrectomy in the coming years.

This paper provides a comprehensive review of vitrectomy surgery, its significance, the diseases it treats, the access issues in Nigeria, and the postoperative care required for optimal recovery. Through a shedding of light on the procedure and impacts, this discussion aims to contribute its share of the larger argument towards improving eye care services in Nigeria and have more patients receive timely and effective treatment.

What is Vitrectomy Surgery?

Vitrectomy is an eye operation involving the removal of the vitreous humor, a clear gel substance that replaces the central cavity of the eye. The procedure is performed to facilitate unobstructed access to the retina so that surgeons are able to repair damage caused by various retinal conditions. It is utilized most commonly to repair retinal detachment, macular holes, vitreous hemorrhage, epiretinal membranes, and retinal diabetic retinopathy secondary complications. Surgeons can remove any scar tissue, blood, or opacities which are interfering with vision and slowing retinal function by simply removing the vitreous.

The method is highly delicate and requires an ophthalmologist with training in vitreoretinal surgery. During the procedure for vitrectomy, very small incisions are made in the sclera (the white part of the eye), and microsurgical instruments are inserted within to excise the vitreous gel. Advanced techniques like laser photocoagulation, membrane peeling, or retinal tamponade can be utilized depending upon the specific ailment that needs to be treated. As the vitreous does not regenerate, it is replaced with an artificial material such as a saline solution, gas bubble, or silicone oil to maintain the shape of the eye and support healing of the retina. The surgeon selects the type of replacement based on the extent of the disease and the nature of the planned treatment.

Vitrectomy is generally performed under general or local anesthesia, depending on the complexity of the case and patient's health status. Surgery can take between one and three hours, and the patient normally leaves the same day. Aftercare is critical because patients may be required to position the head in specific positions—especially when using a bubble of gas—to permit retinal reattachment. Although vitrectomy is highly effective in re-establishing vision and preventing further injury to the eyes, risks include infection, increased intraocular pressure, cataract formation, and, less commonly, re-detachment of the retina. Nevertheless, with ongoing improvement in surgery and postoperative management, vitrectomy remains an essential procedure for preserving vision and improving quality of life in individuals with advanced vitreoretinal disease.

Depending on the specific eye condition being treated, vitrectomy can be categorized into two main types:

Types of Vitrectomy Operation

Vitrectomy is also classified into two types based on the area of the eye and the ailment for which treatment is being sought. They are posterior pars plana vitrectomy (PPV) and anterior vitrectomy. Both of these procedures involve the removal of the vitreous humor, but they differ in intent and performed for other vision ailments.

1.    Posterior Pars Plana Vitrectomy (PPV)

Posterior pars plana vitrectomy is the most common type of vitrectomy and is used to treat posterior segment eye conditions, such as the retina, choroid, and sclera. It is performed through small incisions in the sclera to access the vitreous cavity and retina. It is applied in retinal detachment, diabetic retinopathy, macular holes, epiretinal membranes, vitreous hemorrhage, and certain intraocular infections.

PPV is a highly specialized and sensitive procedure that requires high-level microsurgical techniques, and additional therapies such as laser treatment, membrane peeling, or intraocular tamponade (with the use of silicone oil or gas to facilitate healing of the retina) are generally done. The success of PPV depends upon the severity of the disease and the general condition of the eyes of the patient, but it has been extremely successful in correcting vision loss and blindness.

2.    Anterior Vitrectomy

Anterior vitrectomy is a less common but still important operation performed when the gel of the vitreous migrates forward into the anterior chamber of the eye, usually due to trauma, complications of cataract surgery, or other surgical procedures. This migration can lead to such problems as inflammation, prolonged visual interference, glaucoma, or retinal damage. Anterior vitrectomy is the removal of the displaced vitreous gel gently to prevent later ocular issues and maintain the structural integrity of the eye. Unlike PPV, this is generally quicker and is performed as part of some other eye procedure, such as cataract extraction or corneal surgery. While it is simpler than posterior vitrectomy, it needs to be carried out with caution in order to prevent complications such as infection, intraocular pressure alteration, or damage to other eye structures.

General Steps in Vitrectomy Surgery

The surgery requires finesse and application of strict sterile conditions to minimize complications. The procedures of vitrectomy surgery are typically:

1.    Anesthesia – General or local anesthesia is applied based on the magnitude of the procedure and the status of the patient.

2.    Incision – Tiny incisions (sclerotomies) are made in the sclera (the white of the eye) to allow passage of microsurgical instruments.

3.    Vitreous Extraction – A vitrectomy device is used in removing the vitreous gel, as well as scar tissue, debris, and hemorrhagic material obstructing vision.

4.    Therapeutic Procedure – Based on the requirement, corrective treatments can involve laser photo-coagulation, membrane stripping, or retinal re-attachment.

5.    Filling of Eye – The vitreous cavity is filled with an interim replacement medium such as saline solution, gas, or silicone oil to stabilize the retina.

6.    Closure – The incisions are sutured or sealed naturally depending on the surgical technique used. Check us out via WhatsApp | Phone Call | Email

Conditions that Require Vitrectomy Surgery

Vitrectomy is most often the treatment of choice for most retinal and vitreous disorders. Among the most common conditions requiring vitrectomy are:

1.    Rhegmatogenous Retinal Detachment (RRD) – This occurs when the retina becomes detached from the underlying tissue due to a tear or a break. It is one of the leading causes of vision loss and must be addressed immediately with surgery.

2.    Diabetic Retinopathy – A dangerous complication of diabetes that results in abnormal blood vessel growth, vitreous hemorrhage, and tractional retinal detachment.

3.    Vitreous Hemorrhage – Bleeding in the vitreous gel from conditions like diabetes, hypertension, or trauma, leading to sudden vision loss.

4.    Macular Hole – A small tear in the central region of the retina that affects fine vision, often requiring vitrectomy for restoration of visual function.

5.    Epiretinal Membrane (ERM) – A fibrous layer that forms on the surface of the retina, causing distortion and blurring of vision.

6.    Endophthalmitis – Intraocular infection that necessitates evacuation of infected vitreous to prevent further damage.

7.    Eye Trauma – Blunt trauma that causes retinal tears, foreign body impaction, or hemorrhage can be corrected by vitrectomy.

8.    Complications of Cataract Surgery – Vitrectomy may be needed to correct complications like dropped lens pieces or persistent vitreous opacity.

9.    Sickle Cell Proliferative Retinopathy – A retinal complication of sickle cell disease leading to hemorrhage and retinal ischemia. Speak with our best doctors in Abuja, Lagos and PortHarcourt today to book a session. WhatsApp | Phone Call | Email

1.    Rhegmatogenous retinal detachment (62%)

2.    Diabetic retinopathy (10%)

3.    Traumatic injuries (6%)

Diagnosing Conditions that Need Vitrectomy

Diagnosing conditions requiring vitrectomy involves a thorough ophthalmic assessment, including:

1.    Visual Acuity Test – Measures the clarity of central and peripheral vision.

2.    Slit-Lamp Examination – Magnifies the structures of the eye to note deviations in the lens, vitreous, and retina.

3.    Dilated Eye Exam – Makes use of special drops in the eyes to dilate the pupil and view the retina more clearly.

4.    Optical Coherence Tomography (OCT) – A test with no surgery involved that provides high-quality cross-sectional views of the retina.

5.    Fluorescein Angiography – Uses a fluorescent dye to highlight retinal vessel pathology.

6.    B-scan Ultrasonography – Helps to detect retinal detachment or vitreous hemorrhage in cases where the retina is occluded. Book a session now WhatsApp | Phone Call | Email

Alternatives to Vitrectomy Surgery

While vitrectomy is the treatment of choice for most conditions, there are also other treatments to consider, including:

1.    Pneumatic Retinopexy – A bubble of gas is injected into the eye to reattach the retina in some cases.

2.    Laser Photocoagulation – Seals retinal tears and fixes diabetic retinopathy.

3.    Anti-VEGF Injections – Prevents swelling and abnormal vessel growth in macular degeneration.

4.    Observation – In milder cases, observation alone is sufficient.

Complications and Risks of Vitrectomy

Vitrectomy is a very successful surgery, but it may carry risks, which can include:

1.    Infection (Endophthalmitis)

2.    Bleeding in the eye

3.    Retinal detachment

4.    Cataract development

5.    Glaucoma (Elevated intraocular pressure)

6.    Vision loss in rare cases

Recovery and Postoperative Care

Recovery from vitrectomy surgery is slow and requires strict adherence to postoperative guidelines:

1.    Eye Protection – Use a shield or patch to prevent accidental trauma.

2.    Medications – Eye drops and antibiotics to reduce inflammation and infection.

3.    Head Positioning – In cases of gas bubble, face-down positioning can be necessary.

4.    Activity Restrictions – Heavy activities are to be avoided for a few weeks.

5.    Follow-Up Visits – Regular follow-up visits to monitor healing and identify issues early.

Conclusion

Vitrectomy operation is a major development in the treatment of vitreoretinal disease, particularly in Nigeria, where retinal disease is one of the main causes of visual impairment and blindness. Despite being constrained by high cost, limited availability of specialized equipment, and paucity of trained vitreoretinal surgeons, the operation remains crucial in the treatment of complicated eye conditions such as retinal detachment, diabetic retinopathy, and vitreous hemorrhage. Since medical technology continues to improve surgical procedures and patient recuperation, vitrectomy has become a highly successful alternative to restore vision and improve the quality of life in patients with complex retinal disease.

Expanding vitrectomy access in Nigeria is a mix of investment in training specialist ophthalmologists, the development of healthcare infrastructure, and making the procedure more affordable. Collaboration among government agencies, private hospitals, and international organizations can bridge the accessibility gap, allowing more patients to gain from effective and timely intervention.

Since there is continued innovation in surgical technology and health policy, vitrectomy can play an even greater role in reducing preventable blindness and increasing eye care services across Nigeria. Visit SURJEN Healthcare today WhatsApp | Phone Call | Email
