ULTRASOUND BIOMICROSCOPIC ASSESSMENT OF ANGLES BEFORE AND AFTER LASER PERIPHERAL IRIDOTOMY IN PRIMARY ANGLE CLOSURE AND PRIMARY ANGLE CLOSURE GLAUCOMA PATIENTS
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 5
Abstract
BACKGROUND Acute angle closure glaucoma is a potentially preventable condition and hence early identification and treatment of susceptible patients is of utmost importance. Screening, thus is essential so that timely management can prevent irreversible visual loss. Ultrasound biomicroscopy (UBM) is an imaging modality that has near light microscopic precision for examination of anterior segment. The aim of this study is to study the angle morphology before and after laser peripheral iridotomy in patients with primary angle closure and primary angle closure glaucoma. MATERIALS AND METHODS This prospective observational study done among 50 patients who fulfilled the inclusion exclusion criteria and consented for the study were adequately evaluated with a complete history, assessment of anterior segment which includes slit lamp examination, gonioscopy by Goldman 3 mirror goniolens, IOP measurement by applanation tonometry, fundus examination using +90D lens and standard automated perimetry. Depending on the clinical findings, the patients were grouped under PAC or PACG. Then Ultrasound biomicroscopic assessment performed by OTI using 35/16 Hz transducer probe was done prior to and 2 weeks after laser peripheral iridotomy. RESULTS Among the 50 patients of study group, 24 had PAC and 26 had PACG. Of the studied population, among PAC group patients 6 were less than 50 years, 16 were between 51 - 60 years and only 2 were above 60 years. Among the PACG group patients, one patient was less than 50 years, 14 were between 51 - 60 years and 11 were more than 60 years. Among the PAC group, 50% were males and remaining 50% were females. Among the PACG group, 53.8% were males and remaining 46.2% were females. There was an increase in the values of AOD, ACD, TIA, TCPD and ILA. There was a significant decrease in ILCD. CONCLUSION Among the studied population, observation in the angle characteristics showed that there was statistically significant change in the UBM parameters noted in the primary angle closure group; however, in primary angle closure glaucoma no such significant change was noted.
