Abstract

Background and objective: A pterygium is a triangular fibrovascular subepithelial ingrowth of degenerative bulbar conjunctival tissue over the limbus onto the cornea. Excision is indicated if the pterygium approaches the visual axis, causing loss of vision from irregular astigmatism or in cases of considerable irritation. This study aimed to determine the percentage of astigmatism in patients presented with pterygium and measure the effect of size (width and height) of pterygium on a degree of astigmatism and indication of early surgery.Methods: A hospital based cross-sectional study using non-probability convenience sampling was conducted in the ophthalmology department of Rizgary and Erbil teaching hospital in Erbil city from June 2015 to February 2016. Ninety-six eyes of eighty patients with pterygium were included in this study.Results: The mean age ± SD of the 80 patients included in the study was 37.5 ± 9.62 years ranging from 22-58 years. There were 45 male and 35 female patients. Two-thirds of eyes (72.6%) had with-the-rule astigmatism while 12.6 % of eyes had against-the-rule astigmatism. A highly significant strong correlation was seen between a fraction of corneal area encroached by pterygium with induced astigmatism (r = 0.727, P <0.001). A highly significant strong correlation was found between the area of pterygium and corneal astigmatism in a case of severe pterygium (pterygium encroaching > 4 mm area on the cornea) (r = 0.802, P <0.001).Conclusion: Pterygium size has a significant correlation to the amount of induced astigmatism. The correlation is stronger in the pterygia of severe degree (>4 mm) as in this group they are encroaching on the visual axis.

Abstract

Background and objective: Myopiais a common refractive error in the estimation of corneal barrier and well-beingof endothelial function, the central corneal thickness is important to manage corneal diseases. This study aimed to explore the relationship between central corneal thickness, axial length and myopia among a sample of patients in Erbil.Methods: This cross-sectional study was conducted from June 2015 to February 2016. Forty six emmetropes as a control group and 46 myopes were studied. Axial length was measured with A-scan ultrasound biometry and central corneal thickness with corneal topography. Central corneal thickness was correlated with myopia and axial length using the Pearson’s correlation coefficient.Results: This study included 92 patients. The mean age of myopes was 31.87 years and 33 years for emmetropes. Myopia ranged from –0.5 to –11 diopters. The mean central corneal thickness was 541.80 micrometers for myopes and 548.93 micrometersfor emmetropes. The mean axial length was 25.77 millimetersfor myopes and 24.37 millimetersfor emmetropes.The Pearson’s correlation coefficient (r) of the central corneal thickness and myopia was -0.0245 (P =0.872), while that of the central corneal thickness and axial length in myopes was 0.035 (P = 0.566) and of the central corneal thickness and axial length in emmetropes was 0.26 (P = 0.091).Conclusion: There was no correlation between central corneal thickness, axial length and myopia.

Abstract

Background and objectives: Although a lot of studies suggested the predisposition of many risk factors, non-arteritic anterior ischemic optic neuropathy was considered for a long time to be idiopathic. This study aimed to assess the relationship between different factors and anterior ischemic optic neuropathy among a sample of patients in Erbil city.Methods: A case-control study was conducted in Erbil city, Iraq from 2008 to 2011. A total of 36 cases of non-arteritic anterior ischemic optic neuropathy and 36 controls with other visual problems were included.Results: Eight percent of patients in this study had one or more risk factors (P = 0.001), in particular hypertension and diabetes were shown to have a significant relationship (P = 0.046 and 0.001, respectively). The absence of physiological cup over the optic disc has crucial importance both independently (P = 0.001) and in association with diabetes (P = 0.001). Old age and male gender were significant factors in relation to co-morbidities (P = 0.001 and 0.038, respectively).Conclusion: The study had concluded that hypertension, diabetes, age, male gender and absent physiological cup over the optic disc were important risk factors for anterior ischemic optic neuropathy.

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 µm in male eyes and 530.1 ± 32.5 µm 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.

Abstract

Background: Cystoid Macular Edema (CME) in its various forms can be considered one of the leading causes of central vision loss in the developed world. It is not a disease itself, It represents a common pathologic sequel of the retina and occurs in a variety of pathological conditions such as, diabetic retinopathy, central or branch retinal vein occlusion(CRVO,BRVO), intraocular inflammation and following cataract extraction. Objective: This study was done to investigate the pattern of CME in patient attending Erbil Teaching Hospitals.Type of the study: Cross- sectional study.Methods and Materials: This is a hospital base cross- sectional study that included 61 patients (75 eyes) conducted at Erbil Teaching Hospitals for six months. All patients underwent a comprehensive assessment including medical and ophthalmic history, detailed ophthalmic examination and Optical Coherence Tomography (OCT) examination.Results: of the 61 patients 32 (52.5%) were females and 29 (47.5%) were males. The mean age was (56.4±10.8) years. Out of the 75 eyes included in the study, 41 eyes (54.66%) had diabetic retinopathy, 10 eyes (13.34%) had CME following cataract operation (Irvine-Gass syndrome), 8 eyes (10.67%) had BRVO, 6 eyes (8%) were had CRVO, 5 eyes (6.66%) had age related macular degeneration, 3 eyes (4%) with uveitis, and 2eyes (2.67%) had Retinitis Pigmentosa. The average macular thickness was (415.6± 107).Conclusions: Diabetic retinopathy is the most common predictive factor of CME, followed by cataract surgery. CME is more severe in diabetic retinopathy, CRVO and after cataract surgery.

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.
