ABSTRACT
Objective: To evaluate the efficacy and safety of trans pupillary diode laser retinopexy for the management of retinal tears as an outpatient ophthalmic procedure.
Study Design: Retrospective study
Place and Duration of Study: This study was conducted at the Multan Medical and Dental College and Bodla Eye Care, Multan from January 2018 to June 2018.
Materials and Methods: The long wave 810nm diode laser retinopexy was done instead of conventional argon laser retinopexy as an outpatient procedure. A moderate spot size between 300 to 400 microns with diode laser (810) was used to treat patients with breaks in attached retina. Powers between 400 and 800 mW produced an adequate burn in all cases. Pre and post laser anterior and posterior segment examination was done for any signs of inflammation, and PVR. Follow up was conducted, for over a period of six months, to ascertain for adequate chorio-retinal adhesions.
Results: A total of 13 patients were recruited in the study starting from February 2018 till July 2018. There were 13 eyes in total with the mean age of 57.8 years. Pre laser VA of 7 eyes was between 6/6 to 6/12 and 6 eyes had a visual acuity of 6/18 to 6/60. Post laser VA, improved to 6/6 to 6/12 in 10 eyes as associated vitreous haemorrhage resolved, and remained between 6/18 to 6/60 in 3 eyes. Out of 13 eyes, none of the eyes, developed anterior segment inflammation while mild posterior segment inflammation, was noticed in one eye. None of the eyes developed PVR. Excellent chorio-retinal adhesion was achieved in 12 out of 13 eyes. One eye with failure needed, scleral buckling procedure, this was with pre clinical rhegmatogenous retinal detachment having U shaped retinal tear.
Conclusion: Our study looked at the efficacy and safety of transpupillary diode laser which had been the main stay treatment for retinal tears prior to introduction of Argon laser primariloy used for the mentioned procedure now a days.Excellent chorio-retinal adhesion was achieved in 12 out of 13 eyes. There was no element of proliferative vitreo retinopatrhy noticed in either eye as a result of the procedure. Results of diode laser were found to be at par with Argon and definitely superior to trans sclera cryopexy. Cryopexy is known to cause scleral thinning, proliferative vitreo retinopatrhy, tissue necrosis along with breakdown of blood aqueous barrier and none of these complications are associated with diode laser.
