Vitrectomía pars plana (VPP)
Understanding Pars Plana Vitrectomy
In this section we explain what VPP is and why it is performed, so that you understand the basics before considering surgery.
PPV involves removing the vitreous humor, a clear, gel-like substance that fills the space between the lens and the retina. The procedure allows unobstructed access to the retina. The term pars plana refers to the chosen entry point in the white of the eye. This area provides a safe route to the retina and avoids damage to surrounding tissue. By removing the vitreous humor, the surgeon can repair tears, remove scar tissue, or apply laser treatment with greater precision. The vitreoretinal surgeon uses modern diagnostic technology and an individualized approach for each patient, all with the goal of preserving vision and quality of life.
Common Conditions Requiring PPV
Various diseases of the retina and vitreous humor may require a pars plana vitrectomy to restore vision and prevent complications.
When the retina separates from the underlying layer, VPP allows it to be repositioned and secured, preventing permanent vision loss. Bleeding within the vitreous humor, often associated with diabetic eye disease, blurs vision. Removing the blood with vitreous humor clears the visual field and facilitates subsequent repairs. A small tear in the macula distorts central vision. Using positive pressure refractive surgery (PPV), the specialist treats the tear and improves visual clarity. Scar tissue that forms over the retina causes wavy vision. PPV provides access to carefully remove the membrane. Injuries or infections can leave debris or scar tissue in the eye. PPV removes these elements and promotes healing.
Benefits of Pars Plana Vitrectomy
PPV offers significant improvements when other options are not enough to protect vision.
By removing the cloudy or debris-filled vitreous gel, the surgeon obtains a clear view that facilitates delicate treatments such as laser or membrane peeling. La intervención temprana reduce el riesgo de daño permanente en afecciones como hemorragia vítrea o desprendimiento de retina. La VPP permite aplicar procedimientos altamente especializados dentro del ojo, logrando correcciones que no serían posibles desde el exterior.
Técnica y Proceso Quirúrgico
A continuación detallamos cada paso del procedimiento para que sepa qué esperar antes, durante y después de la cirugía.
Pruebas como tomografía de coherencia óptica, fotografía de fondo de ojo y, en algunos casos, ecografía ayudan a planificar la intervención con exactitud.
Según la complejidad del caso se utiliza anestesia local o general, garantizando comodidad completa durante la cirugía.
Se practican pequeñas incisiones en la pars plana de la esclerótica. El tamaño reducido favorece una recuperación más rápida y menos complicaciones.
Con instrumentos de corte microscópicos se retira gradualmente el vítreo, despejando la vista y brindando acceso a la retina.
El cirujano vuelve a colocar la retina, sella desgarros con láser o retira tejido cicatricial, siempre con alto nivel de precisión.
Al finalizar, se introduce un sustituto que mantiene la forma ocular y apoya la retina mientras cicatriza.
- Burbuja de gas: se disuelve en semanas y puede requerir posición específica de la cabeza.
- Aceite de silicona: permanece más tiempo y suele retirarse en una cirugía posterior.
- Solución salina balanceada: se usa cuando no se necesita tamponamiento interno.
What to Expect During Surgery
The following timeline summarizes the main steps of the procedure so that you feel informed and at ease.
Your medical history is reviewed and appropriate anesthesia is administered to ensure a pain-free experience. The specialist makes micro-incisions in the pars plana and introduces the necessary instruments. The vitreous humor is removed using small-caliber tools that minimize eye trauma. Lasers, tweezers, or other techniques are used to repair the retina or remove tissue that affects vision. The internal space is filled with gas, oil, or saline solution to support the retina during healing.
Recovery and Aftercare
Proper recovery is essential to optimize results and protect your vision in the long term.
You may experience sensitivity and blurred vision. A protective patch and prescription eye drops help prevent infection and inflammation. Follow-up appointments allow the specialist to monitor healing and adjust treatment if necessary. If gas was used, head positioning is key to success. It is recommended to avoid strenuous activity and heavy lifting for the first few weeks. The eye drop regimen helps reduce inflammation, prevent infections, and promote eye comfort. Follow the prescribed plan.
Potential Risks and Their Management
All surgical procedures carry risks, although the surgeon's experience and careful follow-up minimize them.
It is uncommon and can be prevented with antibiotic eye drops. Report any persistent pain or redness. It can be temporary. The specialist monitors the blood pressure and prescribes treatment if it rises. Over time, clouding of the lens may develop. The patient is informed before surgery so they can be prepared. In some cases the retina may detach again and require further treatment.
Preventing Future Vision Problems with PPV
Pars plana vitrectomy is an effective tool for halting the progression of vision-threatening diseases and, in many cases, restores visual clarity.
By eliminating bleeding and scar tissue, VPP reduces vision loss and improves quality of life. Treating the underlying cause decreases the likelihood of further damage and protects long-term eye health.
