ABSTRACT
Background and objective: Cataract and glaucoma are common co-morbidities and are the first and the second leading causes of blindness worldwide. There are many reasons to consider cataract extraction in individuals with cataract. These individuals derive great visual benefit from the increased acuity and improved contrast sensitivity provided by a clear artificial lens. An improvement in vision allows for more accurate visual field monitoring, and a clear optical pathway enhances the quality and reproducibility of optic nerve imaging. This study aimed to determine the association between intraocular pressure with cataract surgery in human eyes by monitoring changes in intraocular pressure in patients who underwent cataract surgery at Hawler Teaching Hospital at Erbil
Methods: This cross-sectional study was conducted on 71 subjects that underwent cataract surgery at Hawler Teaching Hospital at Erbil city from April 2013 to April 2014. Full ophthalmic examination including intraocular pressure measurement was done to every participant before cataract surgery, one week and one month after surgery
Results: Paired samples t-test showed highly significance difference [P <0.001] between mean intraocular pressure measurements before, one week and one month after cataract surgery. The average decrease in postoperative intraocular pressure from preoperative intraocular pressure during one month was 2.02mm Hg [12.39%]
Conclusion: Cataract surgery reduces intraocular pressure and can be considered as an effective way to manage patients with a concurrence of glaucoma and cataracts
ABSTRACT
Background and objective: A thin central corneal thickness has been reported to be a risk factor for developing primary open-angle glaucoma. This has led to a hypothesis that thinning of the cornea may be an indication of generalized weakness of the ocular integument. This study was conducted to explore the relationship between central corneal thickness and axial length in a sample of Erbil population
Methods: This is an observational cross sectional prospective study that was conducted from October 2012 to March 2013 and included 260 eyes of 130 patients. The mean age [+/- SD] was 37.8 +/- 17.7 years for males and 35.4 +/- 15.5 years for females. Axial length was measured with A-scan ultrasound biometry and central corneal thickness with ultrasonic Pachymeter
Results: The mean central corneal thickness [+/- SD] was 542.8 +/- 36 microm in male eyes and 530.1 +/- 32.5 microm in female eyes. The mean axial length [+/- SD] was 23.38 +/- 1.1 mm in male eyes, 23.15 +/- 1.2 mm in female eyes. Central corneal thickness was not correlated with axial length [Pearson correlation coefficient r = 0.037, P = 0.558]
Conclusion: Central corneal thickness and axial length of the eye are two independent measurements. Thin corneas are not related to longer eye
