RESULTS OF SLT IN POST PKP EYES WITH SECONDARY OPEN ANGLE GLAUCOMA.

To evaluate the effect of selective laser trabeculoplasty in post penetrating keratoplasty eyes with secondary glaucoma in a tertiary referral institute in eastern India.

in a tertiary referral institute in eastern India.

PROSPECTIVE INTERVENTIONAL CASE SERIES.

22 EYES OF 22 PATIENTS WHO HAD UNDERGONE PKP AND HAD DEVELOPED SECONDARY OPEN ANGLE GLAUCOMA .

ONLY PATIENTS WITH 360 DEGREE OPEN ANGLES ON GONIOSCOPY WERE SELECTED.

THEIR VISION, GRAFT STATUS, ANTERIOR CHAMBER REACTION WERE NOTED.

IOP S WERE MEASURED WITH TONOPEN. THREE READINGS WERE TAKEN WITH 5% CONFIDENCE INTERVALS.

THE ARITHMETIC MEAN OF THE THREE READINGS WERE CALCULATED.

ALL THE ABOVE MENTIONED PARAMETERS WERE RECORDED

PRE OP/ I HOUR

POST OP, I DAY POST OP

AND 1 MONTH POST OP.

IN ALL THE EYES SLT WAS DONE 360 DEGREES FOLLOWING THE ACCEPTED GUIDELINES

1 MONTH POST OP IOP10.6 – 40 M- 18. (SD- 12.42. CI- 12.42- 23.57.)

COMPARING THE PRE SLT IOP WITH POST OP I HOUR, I DAY AND I MONTH POST SLT DATA BY THE UNPAIRED t TEST REVEALED P VALUES OF 0.60, 0.29, 0.322 RESPECTIVELY.

THESE DIFFERENCES WERE STATISTICALLY NOT SIGNIFICANT.

SLT DOES NOT SEEM TO HAVE ANY STATISTICALLY SIGNIFICANT EFFECT IN IOP LOWERING IN POST PKP GLAUCOMA IN THE PRELIMINARY EARLY FOLLOW UP PERIOD.

FURTHER FOLLOW UP MAY REVEAL WETHER THIS STANDS TRUE FOR LONGER FOLLOW UP PERIODS.

POST PKP EYES MAY HAVE CHANGES IN TRABECULAR MESHWORKS WHICH DO NOT REACT FAVOURABLY TO SLT AS FAR AS IOP REDUCTION IS CONCERNED BUT NO PAS FORMATION WAS NOTED.

BUT SOME INDIVIDUAL CASES MAY RESPOND AT LEAST BY MEANS OF DECREASED DRUG REQUIREMENT.
