Trabeculectomy and Iridencleisis is a well known operation. This study has been conduc­ted to compare the results of trabeculectomy, transposition of Scleral Flap and iridencleisis.


  Materials and methods Top


The main criteria observed in our study is postoperative control of tension. In our series, there was no choice of age, sex and types of Glaucoma [Table - 1].


  Operation procedure Top


Steps of trabeculectomy operations and iri­denclesis are well known.

In aphakic glaucoma, central open sky vitrectomy is performed with aspiration of ½ to 3/4 ml of vitreous; and synechiae at the angle is broken slowly by Iris repositor and saline jet.

The scleral flap is stitched and air injected through previous paracentesis, and conjuncti­val flap sutured.

Postoperative complications were studied [Table - 2]

2. Scleral Flap Transportation

Limbal based 6 to 8 mm conjunctive-tenons flap raised; 3x3 mm one third thickness of scleral flap is raised, hinged on the fornix side. The middle flap of one third thickness hinged on the limbal side is dissected, 2x2 mm window from the remaining one third thick­ness dissected as in trabeculectomy. The superficial flap is introduced into anterior Chamber and the middle flap brought out covering the outer one. Conjunctiva and tenons sutured. Saline or air in anterior chamber is optional.

3. Iridencleisis as usual two pillars

Post-operative tension has been recorded upto 3 weeks, weekly and followed onward and compared with the preoperative tension as shown in [Table - 3].


  Discussion Top


Trabeculectomy and Russian Scleral Flap transposition, both having a scleral protection and the bleb is diffuse, thin, little away from the limbus, as opposed to Iridencleisis, which is overhanging the cornea in many cases. Heavy vascularisation is noted when heavy cauterisation was done in both trabeculectomy and Russian operation especially in conges­tive glaucoma cases.

Both operations, Trabeculectomy and Russian can be done at any place around the limbus and can be repeated. Iridencleisis is usually done at 12 O'clock and rarely at 6 o'clock. Cosmetically, Iridencleisis is not accepted. Trabeculectomy and Russian opera­tion are more physiological as we do not dis­turb any other structures.

We have noted that increasing lens opacity more common after Iridencleisis in our series in 12%, and not a single case has been noted in the other operation. Could be due to dis­turbed lens metabolism and touching of Iris pillars on the upper pole of the lens.

Russian Operation is more cumbersome and time consuming without much super added advantage over Trabeculectomy. Iridencleisis is a simple procedure with much more compli­cation and may not be effective in all cases. We confirm that Trabeculectomy is safer, simple and applicable in many cases and a physiological approach without any compli­cations.

Four cases of aphakic glaucoma with ante­rior Synechiae and membrane formation, who came for enucleation were given a chance with Trabeculectomy as described above. Two of them had 6/36 and one had 6/60 vision. This procedure is worth trying in aphakic glaucoma cases.

We have not compared our results of this series with any other but we put before the house our humble opinion that may be bene­ficial to humanity. We are continuing our series and shall report our experiences at a later date.


  Summary Top


Observations of 225 cases of glaucoma following various antiglaucoma operations have been evaluated. We conclude that both Trabeculectomy and Scleral Flap Transposition works nearly by filtration as opposed to pre­vious views.
