Trabeculectomv has been accepted as a valuable surgical procedure, proved easy to perform and method of choice with many, for Glaucoma.
In our previous communications evaluation of Standard Trabeculectomy (S.T.) has been put forth with high success rates in raised Intra Ocular Pressure (I.O.P.) upto 40mm Hg. and some failure rates in I.O.P. above 40mm.
We have devised a variation from the S.T. wherein the inner scleral flap is not excised but everted upon and sutured to the outer one.
| MATERIALS & METHODS:|| |
We have selected fifty eyes of Chronic Simple Glaucoma [Table - 1] with I.O.P. above 4llmm [Table - 2] with no choice of age or sex, with post operative follow up, ranging from 2 to 16 months.
| Procedure|| |
Routine operation of trabeculectomy is performed except the inner flap which is not excised but everted upon and sutured to the outer one.
Post operative tensions were recorded - first, second, six weeks and onwards [Table 3].
Formation and health of the filtering bleb, complications such as hyphaema, lens opacity, anterior chamber etc. remains the same as S.T. except little prolonged shallowness of anterior chamber.
| Discussions|| |
Trabeculectomy with formation of the valve by the everted inner scleral flap, helps in lowering and maintaining the high I.O.P. to an acceptable level which is encountered in various ways. The inner everted flap remains in constant action with the pressure and the movement of the upper lid. The smooth surface of the inner flap delays adhesions. Various possible routes of aqueous seepage are the inner cut ends of Schlemm's Canal through cut ends of scleral vessels, inner window, through the thinner outer scleral flap to the sub-tenon space.
| Summary|| |
Observation of 50 eyes of Chronic Simple Glaucoma with raised I.O.P. above 40 mm have been evaluated with a scleral flap valve procedure with encouraging results.
