Purpose: The current study utilizes microperimetry and optical coherence tomography angiography (OCTA) to assess the optic nerve head vasculature, retinal microvasculature, and retinal sensitivity before and after silicone oil (SO) removal.

Methods: This prospective observational case series study involved 30 eyes subjected to silicone oil endotamponade. Microperimetry and OCTA were utilized to assess the vascular density (VD) of the macula and optic nerve head, as well as the retinal sensitivity (RS), of the participants preoperatively and 1 month following SO removal.

Article Synopsis
  • - The study investigates the effects of biologic therapy on children with juvenile idiopathic arthritis-associated uveitis (JIA-U) by analyzing data from 35 eyes over various follow-up periods.
  • - Success rates for treatment outcomes showed 77% achieved stable/improved vision and 91% had reduced inflammation after 12 months, while long-term results indicated a peak in complete success at 18 months.
  • - The conclusion highlights that biologic therapy is effective for managing JIA-U, especially in reducing reliance on systemic steroids and maintaining stable vision.

Purpose: Phacoemulsification surgery requires the use of both hands; however, some surgeons may not be comfortable using their non-dominant hand, especially in critical steps such as chopping. This work aims at assessing whether a virtual reality simulator can help cataract surgeons train their non-dominant hand using the capsulorhexis module.

Methods: This was a prospective observational study including thirty ophthalmic surgeons; none of them had previous training on the EyeSi surgical simulator.

Aim: To study the effect of axial length (AL) on quantitative characterization of macular and optic nerve microvasculature using optical coherence tomography angiography (OCTA) in healthy individuals.

Methods: A cross-sectional study where participants were divided into 3 groups according to AL; A: ≤22.5 mm, B: 22.

Purpose: Given their immunocompromised status, uveitis patients should be particularly careful during the COVID-19 pandemic. Treatment compliance and adherence are among the most important patient-related determinants of treatment success.To assess the effect of the COVID-19 pandemic on the management of uveitis patients from their own perspective.

Purpose: To investigate the retinal microvascular and choroidal thickness changes in eyes with active Behḉet's disease posterior uveitis and post-remission.

Patients And Methods: A prospective longitudinal observational analytic study where patients with active Behḉet's posterior uveitis (BU) were assessed by optical coherence tomography angiography (OCTA) and enhanced depth imaging OCT during activity and after remission, for retinal microvascular and subfoveal choroidal thickness (SFCT) changes.

Results: 26 eyes of 20 patients were included.

Purpose: A distinct pattern of granulomatous anterior uveitis, with white anterior chamber (AC) granuloma, has been reported in certain endemic areas. The aim of this work was to compare the outcome of conservative treatment to surgical intervention for the treatment of large AC granulomas presenting with moderate-severe anterior uveitis. The secondary outcome is ultrasound biomicroscopy (UBM) characterization of AC granulomas.

Introduction: Hepatitis B virus (HBV) and hepatitis C virus (HCV) and their long-term sequelae are considered a major health issue in Egypt. The aim of this study is to determine the prevalence of undiagnosed hepatitis B virus (HBV) and hepatitis C virus (HCV) among patients admitted for elective eye surgery in a specialized eye hospital in Cairo, Egypt.

Materials And Methods: This cross-sectional study was conducted in a specialized eye hospital, Cairo, Egypt.

The purpose of the study is to assess the retinal sensitivity, using microperimetry, before and after silicone removal. It included 22 patients admitted for silicone removal after vitrectomy for macula-off retinal detachment. Patients were divided into 2 groups according to the duration of silicone tamponade: Group A: <3 months (included 10 patients), and Group B: 3-6 months (included 12 patients).

Purpose: To evaluate retinal sensitivity in children who are on hydroxychloroquine (HCQ) for systemic lupus erythematosus using microperimetry and compare the results with those of the Humphrey visual field (HVF) 10-2 and spectral-domain optical coherence tomography (SD-OCT).

Procedure: A case-control cross-sectional study including 19 patients (less than 18 years old) on HCQ for at least 5 years. Controls were 21 normal children.

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: One of the methods proposed in cases of difficult airway management in children is using a supraglottic airway device as a conduit for tracheal intubation. The aim of this study was to compare the efficacy of the Air-Q Intubating Laryngeal Airway (Air-Q) and the Cobra Perilaryngeal Airway (CobraPLA) to function as a conduit for fiber optic-guided tracheal intubation in pediatric patients.

Materials And Methods: A total of 60 children with ages ranging from 1 to 6 years, undergoing elective surgery, were randomized to have their airway managed with either an Air-Q or CobraPLA.
