From March 2013 to Jan 2015 for 23 months. A total of 350<br>glaucoma suspect patients were selected. A detailed history of ocular or<br>systemic diseases was taken. Intraocular pressure (IOP) was measured using<br>Goldmann Applanation tonometer. Optical Coherence Tomography (OCT)<br>images were taken using Heidelberg HRA + OCT Spectralis machine.<br>Results: Patients with a mean age of 35 ± 12 years were included. Out of 350<br>patients, 140 (40%) patients were female and 210 (60%) were male. Mean IOP<br>was 25 ± 5 mm Hg, mode was 23 mm Hg and median 26 mm Hg. Out of these<br>350 suspects, only 28 patients were found to have nerve fiber layer thickness<br>outside the normal limits i.e. decreased in half a quadrants or more.<br>Conclusion: Ocular coherence tomography nerve fiber layer thickness analysis<br>is a quick and effective method to diagnose early and borderline cases of<br>glaucoma.<br>Key Words: Optical coherence tomography (OCT), retinal nerve fiber layer<br>(RNFL), glaucoma, intraocular pressure (IOP).</p>}, number={2}, journal={Pakistan Journal of Ophthalmology}, author={Kashif Ali, Abdul Majeed Malik, Saima Irum,}, year={2015}, month={Jun.} }
