The Central India Eye and Medical StudyDr. Vinay Kumar Nangia, Dr. Arshia Matin, Dr. Monika Yadav, Dr. Krishna Bhojwani,Dr. Ajit Kumar Sinha, Dr. Jost Jonas(Presenting Author: Dr. Vinay Kumar Nangia)Intraocular pressure is an important ocularparameter that has significant influence indiagnosis, development and management ofglaucoma. It is known to be an important riskfactor for glaucoma. 1,2 The intraocular pressurehas been determined in population based studiesin different parts of the world including, USA 2 ,Europe 3 , China 4 and Southern India. 5 It was thepurpose of this study to determine theintraocular pressure (IOP) in a population basedstudy in Central India for which data are notavailable and to further assess its ocular andsystemic correlations such as with age, gender,refractive error and blood pressure. Thedistribution of intraocular pressure in apopulation may be considered important in theidentification of glaucomatous eyes and thereforeits determination in population based studies indifferent geographic regions carries significance.Materials and MethodsThe Central India Eye and Medical Study(CIEMS) is a population based study conductedin a rural area about 40 kms from Nagpur. 6 In aninterim analysis, 3393 of 4291 subjects (responserate 79.1%) aged 30 and above were examined.The medical ethics committee of the Suraj EyeInstitute had approved the study protocol and allparticipants had given informed consentaccording to the declaration of Helsinki. Entirepopulation in the villages included in the studywas enumerated. The examination was done atthe Suraj Eye Institute located in Nagpur. Theophthalmic evaluation included visual acuityusing ETDRS charts, refraction, slit lampbiomicrosocpy, applanation tonometry,

Intraocularpressure was recorded with the slit lampmounted Goldmann applanation tonometer,after using proparacaine (%) and a fluoresceinstrip for staining the tear film. The cornealthickness was measured using ultrasoundpachymetry After excluding aphakes andpseudophakes one randomised eye of 3251subjects were included for analysis. Mean agewas 47.22±13.39 (range 20-100) yrs. Meanrefractive error was 0.22±1.51 D (range -20 ±6.00).ResultsThe mean IOP was 13.91mmHg. ±3.22 (range 4 to52 mm Hg). The IOP in males (1503) was 13.92±3.40 mmHg and in females (1748) was13.91±3.05. There was no significant difference(p=0.90) in the IOP between males and females.In univariate analysis, the IOP was significantlycorrelated with myopic refractive error (P
