Serial OCTA Analysis In Glaucoma Patients Following Supra threshold Selective Laser Trabeculoplasty

Aim To analyse the Optic nerve head changes using OCT-A study in glaucoma patients following Supra threshold SLT
Methods A retrospective study was conducted of 42 eyes with POAG treated with SLT at Uma eye clinic with 1 year follow up . All the 42 eyes were treatment naïve. All patients were subjected to optic nerve head OCT-A prior to SLT and at day 1,7 ,1M, 3M, 6M ,1 year. The SSADA was used to analyse the Retinal fibre layer, Vessel density and Ganglion cell complex. 
Results The effect  of  SLT  on  IOP  in  this  study  was  significant  (−7.7%) significant. There were non significant changes in the whole disc vessel density, inside disc vessel   density   and   peripapillary   vessel   density. RNFL   and   GCC   analysis   were   non significant implying the delay in glaucoma progression following SLT.
Conclusion Following SLT there was a significant IOP reduction andchanges observed in optic nerve head OCT A analysis at 1 year , implying delay in glaucoma progrssion
