1. Paracentesis air or gas tamponade +/- macular laser
2. Drainage of SRF air or gas tamponade +/- macular laser
3. Volume reduction, drainage, air injection, +/- macular Laser.
4. PP Vitrectomy: Gas or silicone oil tamponade.
± ILM peeling.
± Photocoagulation at the macular hole edges.

Failed & recurrent cases after PP
vitrectomy including cases with silicone oil
tamponade.
Very atrophic background ; white holes.
Very high myopia with posterior
staphyloma.
INDICATION FOR MACULAR
BUCKLING
Still ret. det. after PPV & S.O tamp. plus mac. PC
Reopening of the hole with re-detachment

A new approach has been
discovered only after finding
clear-cut and constant
anatomical landmarks , to be
able to perform exact macular
buckling

A relatively “simple”, “safe” and “easy”
technique is eagerly welcome
We have developed such a technique

• The macular area is approached between
the superior and lateral rectus muscles.
• Hook the 4 recti with silk sutures.
• The superior oblique muscle is severed which
allows hooking and pulling on the inferior oblique
(IO) muscle belly & to hold its insertion
• This exposes the intra-scleral course of the TLPCA
and the space between the point of intra-scleral
entry of this vessel and the optic nerve sheath
(ONS)
HOW TO EXPOSE THE POSTERIOR POLE
DURING SUGERY
ONS
Press on the softened eye beyond the nasal end of IO insertion to take sutures
on either side of TLPCA

Sever the SO insertion.
Hook the IO inbetween SR & LR.
Soften the eye (paracentesis).
Remove the speculum.
Retract the lateral canthus with a retractor.
Flatten the sclera by gentle pressure with a non toothed forceps.
Take the suture bites at equal distances from the TLPSA.
Use fine round needles.
No need to pull much on the sutures.

Retinal re-attachment: 100 %.
Visual acuity:
One case CF.
Others 3/60 – 6/36.
Intraoperative difficulties:
Orbital fat prolapse: 6 / 26 (23%).
Tearing of sutures: 1 / 26 (4%).
Inadvertent perforation: 1 case (4%).
Subretinal hemorrhage: 1 case (4%).
Malposition of buckle: 1 case (4%).

Macular buckling offers the highest
success rate and best visual results
