clear-cut and constant

anatomical landmarks , to be

able to perform exact macular

A relatively “simple”, “safe” and “easy”

technique is eagerly welcome

We have developed such a technique

1/15/2013

12

• 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%).

after PPV with various types of internal tamponade

and to avoid physical injury to the fovea
