Purpose: The aim of this study was to compare choroidal adjusted flow index (AFI) in healthy, hypertensive & preeclamptic pregnancies using optical coherence tomography angiography (OCTA).
Methods: In this prospective study, healthy, hypertensive & preeclamptic third trimester pregnant women underwent OCTA imaging. 3x3 & 6x6 mm choriocapillaris slabs were exported and the parafoveal area was marked by two concentric ETDRS circles at 1 & 3 mm, centered on the foveal avascular zone.
Purpose: To evaluate sutureless scleral tunnel phaco-assisted cataract extraction in regards to the cumulative dissipated energy (CDE) used, the resulting endothelial cell loss (ECL), and the surgically induced astigmatism (SIA) in advanced cataracts.
Methods: A prospective interventional uncontrolled case series was performed. Patients with advanced cataracts according to the Lens Opacities Classification System III (LOCS III) had sutureless scleral tunnel phaco-assisted cataract extraction.
Purpose: To study the safety and efficacy of 25-gauge trocar-assisted flanged intrascleral sutureless IOL fixation in patients with insufficient posterior capsular support.
Methods: Five aphakic eyes with capsular insufficiency were included in this prospective interventional case series study, at Dar El Oyoun Hospital, Cairo, Egypt. Twenty five-gauge trocar-assisted flanged intrascleral sutureless technique was used for IOL fixation, in which retinal microforceps were used to capture and externalize both haptics through a scleral tunnel.
Purpose: To study the influence of weight reduction after bariatric surgery on the intraocular pressure (IOP), retinal nerve fiber layer (RNFL) thickness, and blood flow of optic nerve head by optical coherence tomography angiography (OCTA).
Methods: This prospective observational cohort study included 60 obese patients. Body mass index (BMI), IOP, RNFL, and ganglion cell complex (GCC) thickness, rim area, and radial peripapillary capillary (RPC) vessel density were assessed before and 3 months after bariatric surgery.
Purpose: The aim of the study is to evaluate the surgical outcome of stab incision glaucoma surgery (SIGS) and compare it with radiofrequency-assisted stab incision in the treatment of uncontrolled open-angle glaucoma.
Patients And Methods: A prospective, interventional study included 50 eyes who were assigned into two equal groups: Group A underwent stab incision procedure with preoperative subconjunctival (SC) mitomycin-C (MMC) and Group B underwent radiofrequency-assisted technique without MMC. Intraoperative and postoperative complications, visual acuity, intraocular pressure (IOP), and bleb status were evaluated up to 12 months.
Purpose: To evaluate a new technique combining intrastromal astigmatic keratotomy (AK) with a laser in situ keratomileusis (LASIK) flap followed by excimer laser photoablation to correct post-penetrating keratoplasty (PKP) high astigmatism and ametropia.
Setting: Kasr El Aini Hospital, Cairo University, Cairo, Egypt.
Design: Prospective interventional uncontrolled case series.
Purpose: To evaluate the efficacy of big-bubble (BB) technique in separating Dua's layer together with the Descemet's membrane endothelial (DE) graft and the effect of 7-day storage of the prepared tissues on the endothelial cells.
Method: This is an experimental study in which 21 human corneo-scleral tissues unsuitable for transplantation were used. Grafts were mounted on artificial chamber; epithelial side-up with BB technique was used to detach the DE graft.
Article Synopsis
- The study aimed to assess the visual outcomes and complications from implanting Artisan iris-claw lenses in children with aphakia and insufficient capsular support.
- The research involved 25 aphakic eyes from 18 patients aged over 2 years, focusing on visual acuity and intraocular pressure at multiple intervals post-surgery.
- Results showed significant improvements in visual acuity after one year, but some complications, including dislocation and pupillary block, were noted.
