Purpose: The purpose of the study was to determine knowledge, practice, and resources available to primary care physicians to diagnose and manage corneal abrasion in Saudi Arabia., Methods: This cross-sectional survey was held in 2017. Family physicians and emergency physicians attending an international conference were surveyed. The questions related to demography, invagination, and tools available in their institute were collected. The questionnaire on how to diagnose and how they manage case of corneal abrasion was also collected using tablet-based software., Results: Two hundred and twenty-five participants participated in the survey. Exposure to eye patients in two-third of participants was too low (93; 39.6%). Resources for diagnosing corneal abrasion were available in limited centers (51; 21.7%). The rate of good practice to manage corneal abrasion was 21.2% (95% confidence interval 16.0; 26.5). Certified emergency physicians ( P < 0.001) and western and central regions ( P < 0.001) were positively associated with good practice. Availability of slit lamp ( P = 0.2) was not significantly associated with the level of practice to manage corneal abrasion. Fluorescein staining and use of cobalt blue light are essential for diagnosing corneal abrasion as per 40% of participants. About 44.7% of participants replied that antibiotics and lubricants should be used to treat. Nearly one-fourth of participants suggested urgent reference to the ophthalmologist. Use of specific antibiotic varied widely; however, ofloxacin was the main choice of antibiotic in treating corneal abrasion., Conclusion: The knowledge and practice among physicians about corneal abrasion were low. Integrating primary eye care into emergency services through provision of required resources and training physicians is recommended., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Middle East African Journal of Ophthalmology.)

Purpose: To investigate the efficacy and safety of illuminated microcatheter-assisted trabeculotomy as a secondary procedure in patients with primary congenital glaucoma (PCG)., Methods: This retrospective case series included patients with PCG who underwent trabeculotomy using an illuminated microcatheter with the intent of catheterizing the full circumference of Schlemm's canal in a single procedure. Success was defined as intraocular pressure (IOP) ≤21 mmHg, with or without the use of glaucoma medications. Clinical examination data were collected for up to 36 months postoperatively., Results: Surgery was performed on 16 eyes of 16 patients. The mean patient age was 75.1 ± 69.4 months (range: 4.0-216.0 months). Complete catheterization was achieved in 11 of the 16 eyes (69%), whereas partial catheterization was achieved in five of the 16 eyes (31%). All eyes had previously undergone surgery for PCG. The mean follow-up duration was 20.3 ± 9.0 months (range, 12.0-36.0 months). IOP was reduced from a mean of 31.8 ± 6.6 mmHg preoperatively to 15.6 ± 3.7 mmHg at the final follow-up ( P < 0.001). The mean preoperative number of glaucoma medications was 3.9 ± 0.5, which was reduced to 1.1 ± 1.6 at the final follow-up ( P = 0.001). Ten (62.5%) of the 16 eyes did not require glaucoma medication by the final follow-up. Early transient postoperative hyphema occurred in six eyes (37.5%). No other complications were noted. All corneas were clear at the final follow-up., Conclusion: Ab externo circumferential trabeculotomy using an illuminated microcatheter may be safe and effective as a secondary surgical option for children with PCG after unsuccessful glaucoma surgery., Competing Interests: There are no conflicts of interest., (Copyright: © 2020 Middle East African Journal of Ophthalmology.)

What Is Known and Objective: Physical bottle characteristics differ of brand name topical glaucoma medications and local generic equivalents. This study compares the bottle characteristics of international topical glaucoma brands versus local brands from the Kingdom of Saudi Arabia., Methods: Data were collected on bottle drum volume, drop volume, bottle squeezability, bottle tip diameter, labels and instructions, cap color coding, and clarity of the drug label. Density-based calculations of drops in bottle volume were assessed using an analytic balance. Bottle tip diameter was measured using 0.05 mm Vernier calipers. A Likert scale-based questionnaire was used to evaluate the subjective opinions of patients on bottle squeezability, clarity of usage and storage instructions, and the consistency of the cap color coding., Results: The volumes of international brands were statistically significantly higher than the local brands ( P < 0.001). A number of drops per bottle and tip diameter were comparable between the international local brands. Cap color coding was inconsistent for international and local brands. Patients were dissatisfied with the label font size. Patients reported that the international and local brands were similar in terms of the ease of opening the bottle, instilling a drop, and the clarity of the instructions; but the local brands were subjectively easier to squeeze than international brands., What Is New and Conclusions: This is the first study to compare bottle characteristics of local Saudi Arabia brands with international brands. The bottle characteristics and patient feedback were similar between the local and international topical glaucoma medications. However, there were differences between the local and international brands in drug volume, bottle squeezability. Hence, patient compliance and drop dosage may differ based on the origin of manufacture., Competing Interests: There are no conflicts of interest.

Purpose: To compare intraocular pressure (IOP) measurements by rebound tonometry (Icare PRO; Icare Finland Oy, Helsinki, Finland) to measurements by indentation tonometry (Pneumotonometer Model 30 classic and Tono-Pen XL; Reichert, Buffalo, NY, USA) in supine sedated children with glaucoma., Methods: Prospective comparative observational study of Saudi Arabian children with glaucoma undergoing chloral hydrate sedation for ophthalmic examination (February 2012 - February 2013). Nonglaucomatous eyes were included as controls. Eyes with corneal scars or prior corneal transplant or lamellar surgery were excluded., Results: Fifty-two eyes (26 OD, 26 OS) of 28 children were included. Thirty-six eyes had glaucoma (32 primary congenital glaucoma, two Sturge-Weber related, and two aphakia related). Sixteen eyes did not have glaucoma (six with pediatric cataract, five normal eyes, two strabismic eyes, two eyes with simple megalocornea, and one eye had peripheral corneal laceration repair. In the glaucoma group, the mean IOP was 17.55 ± 5.97 mmHg (range, 8-31.5 mmHg) with the Icare PRO and 20 ± 6.4 mmHg (range, 8-35.5 mmHg) with the Pneumotonometer from 20.47 ± 6.81 mmHg (range, 10-43 mmHg) with the Tono-Pen XL. The Icare PRO readings were significantly lower than each of the indentation tonometers. For the control group, there was no statistically significant difference in IOP measured by the Icare PRO and the indentation tonometers., Conclusions: In this population of supine sedated children with glaucoma, IOP measurements with the Icare PRO tend to be lower than readings from the Pneumotonometer and Tono-Pen XL.

In this brief communication, we present the steps used to establish a web-based congenital glaucoma registry at our institution. The contents of a case report form (CRF) were developed by a group of glaucoma subspecialists. Information Technology (IT) specialists used Lime Survey softwareTM to create an electronic CRF. A MY Structured Query Language (MySQL) server was used as a database with a virtual machine operating system. Two ophthalmologists and 2 IT specialists worked for 7 hours, and a biostatistician and a data registrar worked for 24 hours each to establish the electronic CRF. Using the CRF which was transferred to the Lime survey tool, and the MYSQL server application, data could be directly stored in spreadsheet programs that included Microsoft Excel, SPSS, and R-Language and queried in real-time. In a pilot test, clinical data from 80 patients with congenital glaucoma were entered into the registry and successful descriptive analysis and data entry validation was performed. A web-based disease registry was established in a short period of time in a cost-efficient manner using available resources and a team-based approach.

Purpose: Listeria monocytogenes is an aerobic, motile, gram positive bacillus recognized as an intercellular pathogen in human where it most frequently affects neonates, pregnant women, elderly patients, and immunosuppressed individuals as well as healthy persons. Ocular listeriosis is rare, most frequently in the form of conjunctivitis, but has been also shown to cause rarely endophthalmitis with pigmented hypopyon and elevated intraocular pressure such as in our case., Materials and Methods: We are reporting one immunocompetent patient presenting with dark hypopyon following laser refractive procedure. His clinical findings, investigations, and further management are all described with relevant literature review of similar cases., Results: Diagnosis of ocular listeriosis was confirmed by positive culture of anterior chamber (AC) aspirate with identification of the above organism. His visual outcome was satisfactory with good preserved vision., Conclusion: We believe that his ocular infection was exogenous and that ophthalmologists should be aware of the causative organisms of colored hypopyon to avoid delayed diagnosis.

Purpose: To describe six cases of anterior orbital and adnexal amyloidosis and to report on proteomic analysis to characterize the nature of amyloid in archived biopsies in two cases., Materials and Methods: The clinical features, radiological findings, pathology, and outcome of six patients with anterior orbit and adnexal amyloidosis were retrieved from the medical records. The biochemical nature of the amyloid was determined using liquid chromatography/mass spectroscopy archived paraffin-embedded tissue in two cases., Results: Of the six cases, three had unilateral localized anterior orbit and lacrimal gland involvement. Four of the six patients were female with an average duration of 12.8 years from the time of onset to presentation eyelid infiltration by amyloid caused ptosis in five cases. CT scan in patients with lacrimal gland involvement (n = 3) demonstrated calcified deformable anterior orbital masses and on pathological exmaintionamyloid and calcific deposits replaced the lacrimal gland acini. Ptosis repair was performed in three patients with good outcomes. One patient required repeated debulking of the mass and one patient had recurrenct disease. Proteomic analysis revealed polyclonal IgG-associated amyloid deposition in one patient and AL kappa amyloid in the second patient., Conclusion: Amyloidosis of the anterior orbit and lacrimal gland can present with a wide spectrum of findings with good outcomes after surgical excision. The nature of amyloid material can be precisely determined in archival pathology blocks using diagnostic proteomic analysis.
