Aim: To study the prevalence of normal tension glaucoma
MATERIALS AND METHODS: A prospective cross sectional study was done on 178 suspects of glaucoma in our OPD from October ’15-March ’17 during which 48 patients were diagnosed as NTG.A detailed history with ocular, fundus examinations, applanation tonometry, gonioscopy and automated perimetry were done.
RESULTS: Out of 48 NTG patients males were 28(58.3%) and females 20 (41.6%),with maximum patients in the age group of 50-59 years. 12 NTG patients had a family H/O POAG. Mean diurnal IOP in NTG eyes was 14-14.9 mm Hg (27%) with positive diurnal variation in 58.3%and CD ratio of 0.6 – 0.7 and 82 eyes had visual field defects. Peripapillary atrophy and superior arcuate scotoma were the most common findings.
CONCLUSION: NTG changes the definition of glaucoma and necessitates the importance of early diagnosis and management which will prevent the patients from further damage that it can cause.
