Abstract :
Aims and Objectives: To correlate 3 important factors central corneal thickness, intraocular pressure and visual field changes in the POAG suspects which it helps to predict the onset of POAG and in early diagnosis.
Materials and Methods: In this prospective study, a total 100 patients from 40 to 70 years of age diagnosed as PAOG suspects were included in the study. Slit lamp bio microscopy, ultrasound pachymetry was done to measure CCT and IOP was measured with Goldman applanation tonometer the visual field assessment was done with the octopus field analyser.
Results: The patient population consisted of 42 females and 58 males with average age of 51.7 years. Significant and moderate positive correlation between the CCT and IOP was observed for the right side (r)=0.39 and left side(r)=0.36 statistically significant (P=0.001). In our study highest percentage of abnormal (glaucomatous) visual field changes was seen in eyes with low CCT (.
Conclusion: Thinner corneal readings in south Indian population especially when presenting at younger age should alarm the ophthalmologist to evaluate the patient thoroughly for glaucoma and should be followed up for the progression of glaucoma.
