Preparation of the ocular surface: Prior to CLET, the eye with LSCD (Figure 5a) undergoes peritomy
(Figure 5b), the fibrovascular pannus tissue is cleared from the ocular surface (Figure 5c), and superficial keratectomy is performed when necessary.
Limbal conjunctival peritomy
performed at the 12 o'clock and a fornix based conjunctival flap was fashioned.
Conjunctival limbal peritomy
was started with two 3 mm oblique relaxation cuts at the 7- and 11-o'clock positions (for the right eye).
of the conjunctiva should kept to a minimum, the rectus muscles should not be pulled excessively, and the long posterior ciliary arteries should be avoided.
Conventional pars plana technique of ROSO include conjunctival peritomy
followed by 20 G sclerotomy that need closure with sutures and 3-4 weeks for that discomfort to recover.
6 Micro incision vitrectomy surgery without peritomy
and suturing facilitates early visual recovery while decreasing patient discomfort, operating time, post-operative inflammation, ocular surface irregularities and surgically induced astigmatism.
In this technique, surface keratectomy and conjunctival peritomy
including the limbal area were performed initially to remove the vascularized pannus tissue, after which cautery was used to achieve adequate hemostasis.
a) Conjunctival peritomy
was carried out and a 6mm triplanar sclerocorneal tunnel made along the marked steeper axis the side incisions is made 180 degrees apart.
PLACEMENT OF DEVICE UNDER A SCLERAL FLAP: To place the Ex-PRESS filtration device, a conjunctival peritomy
, limbal or fornix-based, is first created as in conventional trabeculectomy.
rectus muscles were iso- lated and scleral incision was made to drain the SRF.
Proper aseptic precautions were taken and 7mm conjunctival peritomy
After preparing the patient a conjunctival peritomy
was created at 3 O'clock and at 9 O'clock position.
