No full textHisham M Jammal,1,3 Yousef Khader,2 Riham Shawer,3 Muawyah Al Bdour41Department of Ophthalmology, Jordan University of Science and Technology, Irbid, Jordan; 2Department of Community Medicine, Public Health and Family Medicine, Jordan University of Science and Technology, Irbid, Jordan; 3Department of Ophthalmology, King Abdullah University Hospital, Irbid, Jordan; 4Department of Ophthalmology, The University of Jordan, Amman, JordanPurpose: To determine posterior segment causes of reduced visual acuity after phacoemulsification in eyes with cataract and obscured fundus view.Patients and methods: Retrospective review of medical records of patients with cataract, obscured fundus view, and normal B-scan ultrasonography, undergoing phacoemulsification from May 2005 to March 2012 was conducted. Eyes with fundus pathology, previous trauma, surgery, glaucoma, amblyopia, or uveitic cataract were excluded. Ocular comorbid conditions, preoperative visual acuity (VA), intraoperative and early postoperative complications, and final best corrected visual acuity (BCVA) at 1 month were abstracted from the records.Results: All 201 eyes of 179 patients studied had a preoperative VA of &le;6/60. Preoperative ocular comorbidity was present in 31 eyes (15.5%). Intraoperative complications occurred in 20 eyes (10%). Postoperative complications developed in 34 eyes (17.0%). One month postoperatively, 175 eyes (87.1%) achieved a BCVA of &ge;6/12; whereas 26 eyes (12.9%) achieved a BCVA of &le;6/18. The most common posterior segment causes of reduced VA in the 26 eyes were age-related macular disease in ten eyes (38.5%) and diabetic maculopathy in six eyes (23.1%). Similar fundus pathology was seen preoperatively in the fellow fundus in 10 of the 26 eyes (38.5%).Conclusion: One month after phacoemulsification in eyes with cataract and obscured fundus view, age-related macular disease and diabetic maculopathy were the most common posterior segment causes of reduced final BCVA. To avoid postsurgical dissatisfaction, patients with obscured fundus view in their preoperative eye should be counseled, especially if posterior segment pathology exists in their fellow eye.Keywords: B-scan ultrasonography, fundus view, macula, outcome, phacoemulsifcatio
The Authors Abuse of the Moral Right in the Jordanian Legislation: A Comparative Study
No full textThe moral rights of the author are fundamental and protect their intellect and creativity. Despite its importance to the author in particular and society in general, leaving such rights unrestricted is not acceptable because the objective of the law is to regulate various transactions and relationships between people. Therefore, establishing frameworks governing copyright law is deemed useful. By way of examining Jordanian, local, and international legislation, the researchers find that the legislator has not effectively regulated this matter to prevent the author from exercising their moral rights in a way that harms others. Despite the close connection between the moral right and the economic one, the issue of moral right abuse by the author has not been addressed, even though its elements are present in some of the authors practices. Furthermore, the legal texts tackling the subject are more contentious due to their vague and ambiguous wording, leaving legal interpreters to exert effort to understand the intentions behind these words and terms. In the quest to investigate this topic, the study draws several conclusions, the most important of which is the absence of any obstacle to applying the theory of the authors abuse of their moral rights in their practices. The study also shows that the value of compensation specified in the law is not defined by criteria, making it impossible to estimate the value of the loss suffered by the affected party as a result of the authors exercise of their moral rights, as the value of profit is not identified
Trans-epithelial corneal collagen cross-linking with iontophoresis for progressive keratoconus
No full textThe utilization of artificial intelligence in glaucoma: diagnosis versus screening
No full textWith advancements in the implementation of artificial intelligence (AI) in different ophthalmology disciplines, it continues to have a significant impact on glaucoma diagnosis and screening. This article explores the distinct roles of AI in specialized ophthalmology clinics and general practice, highlighting the critical balance between sensitivity and specificity in diagnostic and screening models. Screening models prioritize sensitivity to detect potential glaucoma cases efficiently, while diagnostic models emphasize specificity to confirm disease with high accuracy. AI applications, primarily using machine learning (ML) and deep learning (DL), have been successful in detecting glaucomatous optic neuropathy from colored fundus photographs and other retinal imaging modalities. Diagnostic models integrate data extracted from various forms of modalities (including tests that assess structural optic nerve damage as well as those evaluating functional damage) to provide a more nuanced, accurate and thorough approach to diagnosing glaucoma. As AI continues to evolve, the collaboration between technology and clinical expertise should focus more on improving specificity of glaucoma diagnostic models to assess ophthalmologists to revolutionize glaucoma diagnosis and improve patients care
Unilateral Corneal Ectasia After Bilateral Transepithelial Photorefractive Keratectomy
No full textWe present the case of a 23-year-old male who experienced vision loss in his left eye 15 months after undergoing bilateral transepithelial photorefractive keratectomy (T-PRK). Despite the absence of any significant preoperative topographical risk factors in either eye, corneal ectasia was later confirmed in the left eye, while the right eye remained normal. Subtle asymmetry in topometric indices and a borderline high Index of vertical asymmetry (IVA) reading suggested the possibility of early subclinical keratoconus, potentially increasing the risk of post-refractive ectasia. The patient received corneal cross-linking (CXL) treatment in the affected eye to halt further progression, while the right eye remained under observation. This report reviews the rare instances of post-refractive ectasia. It highlights the potential role of subtle corneal irregularities in predisposing to ectasia, even without traditional risk factors
Topographic characteristics of keratoconus among a sample of Jordanian patients
No full textAIM:To identify topographic characteristics of keratoconus in a Jordanian sample.METHODS:This study characterized 210 corneas affected with keratoconus presenting to Jordan University Hospital. Patients were diagnosed based on clinical examinations and Pentacam imaging. Eyes of males (n=101) were of a similar proportion to females (n=109). All of the 111 patients were affected bilaterally. Ages ranged between 13 and 44y with a mean age of 25.2y.RESULTS:Results revealed significant differences between males and females at the level of the flat curvature power, basement membrane thickness and size of the anterior chamber. Eyes were arranged in three groups based on severity levels:mild, moderate and severe determined by the mean curvature power (Km). Results show that the flat (K1) and steep (K2) curvature powers, corneal asphericity coefficient (QV), thinnest point, pachy apex and basement membrane thickness are significantly different among the three groups, but not the corneal and anterior chamber volumes. Morphological analyses, based on sagittal maps, show no differences in keratometric values between eyes with different sagittal patterns except for the vertical location of the pachy apex relative to the pupil center and the thinnest point. Eyes with the island front elevation map are significantly more affected than eyes with the U shape and the ridge pattern.CONCLUSION:All keratometric values measured except for corneal and anterior chamber volumes vary significantly with disease severity. The vertical pachy apex location correlates well with severity levels while the horizontal location seems to have no effect. Our study also indicates that front elevation maps may be a better predictor of the severity of keratoconus than sagittal maps
Ocular manifestations of Behçet’s disease in Jordanian patients
No full textAbstractPurposeTo study the prevalence, manifestations and severity of ocular involvement of Behçet’s disease in Jordanian patients.MethodsThe study population consisted of 43 patients diagnosed to have Behçet’s disease through Rheumatologist’s examinations conducted at Jordan University Hospital between January 2002 and July 2009. The sample involved patients who displayed ocular manifestations. This included 18 patients; 12 males and 6 females with a mean age of 35years (SD=17.26). Ophthalmological examinations and retrospective analysis of medical files were carried on.ResultsOcular manifestations were seen in 41.9% of patients. The most common manifestation for Behçet’s disease was vitritis with a prevalence of 55.6%, followed by anterior uveitis and retinal vasculitis (50% for each). On the other hand, the most frequent complications involved were cataract, cystoid macular edema (CMO), posterior synechiae and glaucoma with a prevalence of (44.4%), (33.3%), (11.1%) and (5.6%), respectively.ConclusionThe prevalence and severity of ocular lesions in Behçet’s disease is relatively low in Jordanian patients. This result indicates that early diagnoses and intervention might delay or even prevent vision loss for those patients
