Clinical Overview & Treatment Method
The Vitreo-Retinal Department at Ashvini Netralaya is Tripura’s premier tertiary referral unit for complex posterior segment ocular diseases. Led by experienced vitreo-retinal surgeons, our department is equipped with high-speed micro-incisional vitrectomy surgery (MIVS) platforms, wide-angle viewing systems, and 532nm pure green endolasers. We treat blinding conditions including rhegmatogenous retinal detachments, advanced proliferative diabetic retinopathy, non-clearing vitreous hemorrhage, macular holes, epiretinal membranes, and central retinal vein occlusions.
Our medical retina unit provides cutting-edge diagnostics with high-definition Zeiss Cirrus OCT, fundus fluorescein angiography, and painless intravitreal anti-VEGF therapy (Lucentis, Accentrix, Eylea, Ozurdex, Razumab) administered inside our ultra-clean, HEPA-filtered modular OT suite to guarantee zero-endophthalmitis safety.

Who is an Ideal Candidate for this Procedure?
Retina Treatment Modalities at Ashvini Netralaya
Our vitreo-retinal specialists tailor treatment to the exact pathology, stage, and location of the retinal lesion.
| Option / Type | Vision Range | Night Glare | Spectacle Freedom | Ideal Candidate |
|---|---|---|---|---|
25G / 27G Pars Plana Vitrectomy Surgical Standard | Restores visual field & stops blinding progression | Depends on cataract status / post-op tamponade | Refraction reassessed after gas absorption / oil removal | Retinal detachment, vitreous hemorrhage, macular hole |
Intravitreal Anti-VEGF Injections Minimally Invasive | Reverses central macular swelling & stops leaks | No night glare caused | Preserves fine central reading vision | Diabetic Macular Edema, Wet AMD, Retinal Vein Occlusion |
532nm Green Laser Photocoagulation Preventive Gold Standard | Prevents progression of severe diabetic retinopathy | Temporary dazzle for a few hours post-laser | Maintains current spectacle prescription | Proliferative diabetic retinopathy, peripheral retinal tears |
Scleral Buckling Surgery Alternative Surgical Option | Reattaches peripheral retina from external sclera | Low | May induce slight mild myopic shift | Young phakic patients with dialysis or simple rhegmatogenous RD |
Step-by-Step Procedure at Ashvini Netralaya
Conducted in our modular NABH-accredited operating theatres or diagnostic laboratories with zero-infection sterilization protocols.
Retinal Mapping & Optical Coherence Tomography (OCT)
20 minsHigh-resolution cross-sectional imaging reveals fluid accumulation, tractional bands, and exact tear coordinates.
Peribulbar Anesthesia
10 minsGentle localized block provides complete anesthesia and akinesia, ensuring the eye remains still and comfortable.
25G/27G Sutureless Trocar Insertion
10 minsThree microscopic self-sealing valved ports are inserted into the pars plana for fiber-optic illumination, infusion, and vitrector probe.
Core Vitrectomy & Membrane Peeling
30 - 45 minsClouded vitreous gel is cleared, tractional fibrovascular membranes are peeled with ILM micro-forceps, and subretinal fluid is drained.
Endolaser & Tamponade (Gas / Silicone Oil)
15 mins532nm green laser creates permanent chorioretinal adhesion around all tears, followed by an internal gas bubble or silicone oil tamponade.
Recovery Timeline & Visual Milestones
Postural Positioning & Tamponade Support
Maintain specific head posture (e.g. face-down or side-tilt) as instructed by your surgeon to ensure the gas/oil bubble secures the retinal tear.
- Strict face-down or designated positioning
- Take antibiotic and cycloplegic eye drops
- Avoid sleeping flat on your back
Gas Absorption & Vision Return
Expandable gas bubble slowly shrinks from the top down. A fluid meniscus line will be visible in your lower vision field as sight returns.
- Light household mobility
- Avoid vigorous exercise and sudden jerks
- Strictly no air travel or mountain climbing until gas absorbs
Retinal Stabilization & Oil Removal
Retina is firmly adhered. If medical-grade silicone oil was used, a brief 15-minute day-care procedure is scheduled to wash out the oil.
- Normal routine living restored
- Final spectacle refraction update
- Periodic dilated retinal monitoring
Pre-Procedure Preparation
- •Fasting for 4 to 6 hours prior to surgery if monitored anesthesia care is planned.
- •Bring all previous OCT scans, fundus photos, and systemic diabetic/hypertension records.
- •Continue blood pressure tablets with sips of water; consult doctor regarding blood thinners (aspirin/clopidogrel).
- •Arrange for a family member to accompany you and assist with transport home.
- •Avoid eye rubbing if a retinal tear is suspected; rest quietly with head slightly elevated.
Post-Procedure Guidelines
- •Strictly adhere to the prescribed head posture (prone/face-down or lateral) for 5-7 days.
- •Never fly on an airplane or travel to hill stations until your doctor confirms the gas bubble has dissolved.
- •Do not allow tap water or soap to touch the operated eye for 2 weeks.
- •Wear the protective eye shield continuously during sleep to prevent accidental pressure.
- •Contact the emergency retina helpline immediately if you experience severe sudden pain or sudden darkness.

“My retina suddenly detached and I lost almost all vision in my right eye. Doctors in other clinics asked me to travel to Chennai or Kolkata. Ashvini Netralaya performed the surgery right here in Agartala the very next day. Today my retina is completely reattached and vision is restored.”
