Sustainable drainage systems (SuDS) are nature-based methods of managing urban stormwater runoff. Although they are widely used, some SuDS, such as highway filter drains (HFDs), are understudied with respect to sizing and performance. For the first time, we developed an analytical probabilistic model (APM) that can be used to design and estimate the hydrologic performance of HFDs.

Purpose: The purpose of this study was to correlate between the axial length of the globe and the insertion site of horizontal extraocular muscles using swept-source anterior segment optical coherence tomography (SS-ASOCT), with posing an equation to calculate the muscle insertion site from the axial length.

Methods: The study design was observational and cross-sectional. It was performed on 157 eyes of 157 healthy subjects.

Purpose: The aim of this study is to evaluate the retinal microvascular density in SLE patients using optical coherence tomography angiography (OCTA) and to correlate vascular density with the disease activity and damage risk.

Methods: Twenty eyes of 20 SLE patients were compared with 20 eyes of normal subjects. The retinal capillary plexuses were examined by OCTA.

Purpose: To study the astigmatic correction of high post-keratoplasty astigmatism using Femtosecond laser (FSL)-assisted Arcuate Keratotomy (FS-AK).

Methods: A prospective interventional cohort study. We enrolled 17 eyes with high degree of irregular astigmatism, scheduled for FS-AK.

Aim: To identify CYP1B1 gene mutations and evaluate their possible role as a prognostic factor for success rates in the surgical management of Egyptian congenital glaucoma patients.

Methods: Totally 42 eyes of 29 primary congenital glaucoma patients were operated on with combined trabeculotomy/trabeculectomy with mitomycin-C and followed up at 1d, 1wk, 1, 6 and 12mo postoperatively. Genomic DNA was extracted from peripheral blood leukocytes.

: To determine the prevalence of posterior segment manifestations among consecutive patients with pathological myopia attending our University Hospital general ophthalmology clinic and their association with age, refractive error, axial length and each other. : Patients diagnosed with pathological myopia underwent full ophthalmological examination, optical coherence tomography, fluorescein angiography, and ocular ultrasonography. Manifestations detected were recorded for each eye and their prevalence and association with age, refractive error, axial length and each other was determined.

Objectives: This study was aimed to develop dual-purpose natamycin (NAT)-loaded niosomes in ketorolac tromethamine (KT) gels topical ocular drug delivery system to improve the clinical efficacy of natamycin through enhancing its penetration through corneal tissue and reducing inflammation associated with Fungal keratitis (FK).

Significance: Nanosized carrier systems, as niosomes would provide great potential for improving NAT ocular bioavailability.NAT niosomal dispersion formulae were prepared and then incorporated in 0.

Purpose: To investigate functional and structural outcomes of internal limiting membrane (ILM) peeling during primary vitrectomy for uncomplicated macula-off rhegmatogenous retinal detachment (RRD).

Methods: In this prospective interventional randomized comparative study, 43 eyes (43 patients) were randomly divided into group A (20), and group B (23), with and without ILM peeling respectively. Patients were evaluated clinically, and by spectral-domain optical coherence tomography (SD-OCT) and microperimetry (MP) following silicone oil removal.

Purpose: To assess Visian Implantable Collamer Lens (ICL) (STAAR Surgical, Monrovia, CA) implantation in the ciliary sulcus to correct pseudophakic ametropia in patients who are not candidates for a keratorefractive procedure.

Methods: The authors performed a prospective non-comparative case series study of 18 patients (age: 48 to 61 years) with refractive surprise after phacoemulsification. Patients underwent implantation of a piggyback collagen copolymer lens: V4C design in 16 myopic eyes and V4B design in 2 hyperopic eyes.

Purpose: To study the corneal changes in rheumatoid arthritis (RA) patients in vivo, using spectral domain anterior segment optical coherence tomography (AS-OCT).

Methods: A case-control study was done on 43 RA patients and 40 controls. The disease activity score (DAS28-ESR) was calculated and all participants had lower tear meniscus, corneal thickness, and epithelial thickness evaluation using AS-OCT.

Background/aim: To evaluate the economic burden of intraocular pressure (IOP)-lowering medications on Egyptian patients with glaucoma, in addition to studying the social grounds of glaucoma education.

Methods: In a cross-sectional observational study, the clinical and socioeconomic data were collected from 68 glaucomatous patients who were attending the outpatient clinics of Cairo University Hospital, through interviews, questionnaires, and clinical examinations.

Results: Patients had a mean IOP of 22.

A specialty is the transition from the undifferentiated medical graduate phase to the final, fully-differentiated specialist who is almost restricted to one specialized area of medical work. The medical specialty chosen by the medical practitioner is important for both the practitioner and the society. It is an important determinant of the future supply of doctors in different specialties and the planning of the workforce for the health-care services.
