Aim The aim of this study was to report the epidemiology, clinical characteristics, causes, management, and outcome of neovascular glaucoma (NVG) in a tertiary facility in Egypt (Glaucoma Care Clinic at Cairo University Hospitals).
Patients and methods The demographic and clinical data of 251 eyes diagnosed with NVG were retrospectively studied. The antiglaucoma medications and interventions used for management were reviewed with analysis of the outcome in the form of success rate, final visual acuity (VA) and intraocular pressure (IOP). Complete success was defined as an IOP between 6 and 21 mm Hg without topical or systemic glaucoma medications with preservation of presenting VA.
Results NVG was diagnosed in 7.9% of all glaucoma patients in our clinic. The prevalence was more in men (58.8%), and the mean age was 56.5±11 years. Diabetic retinopathy was the most common cause for NVG (61.4%), followed by central retinal vein occlusion (21.4%). The presenting VA was light perception (LP) or less in 45% of the eyes. Diode laser cyclophotocoagulation was the most common treatment modality used (57%), followed by antiglaucoma medications only in 28% and finally surgery in 15% of the patients. Complete success in the diode group was achieved in 73.43% of the cases compared with 68.42% in the surgery group, with no statistically significant difference (P=0.522). The effect of an intravitreal injection of antivascular endothelial growth factor on the final IOP was significant (P=0.024).
Conclusions NVG has a high prevalence in our glaucoma patients. The patients presented very late, with nearly half of the patients having VA of LP or less. This led to decreased resort to surgical intervention. Diode laser cyclophotocoagulation was the main treatment modality used, with significant control of the IOP.

Tomairek, R. H., M. M. Amin, K. A. Raafat, S. Abdelhady, and A. Elkotoury, "Prevalence of Congenital Ocular Anomalies among Children with Genetic Disorders: An Egyptian Study.", Seminars in ophthalmology, vol. 33, issue 5, pp. 613-619, 2018. Abstract

PURPOSE: To assess the pattern and frequency of occurrence of ocular anomalies among other genetic disorders in Egypt.

METHODS: This is a cross-sectional study of 2500 cases presenting with genetic disorders. Cases were recruited from the clinical genetics department of the National Research Centre (NRC) over a four-year period between January 2011 and December 2014. Ophthalmological examination of the cases was performed in the pediatric ophthalmology department of Cairo University Hospitals.

RESULTS: Out of 2500 cases with congenital disorders, 2.4% suffered one or more ocular anomalies with a male to female ratio of 1.7:1. Consanguinity was reported in 76.7% and family history was positive in 35% of ocular cases. The most common ocular anomalies were congenital cataract, retinal dystrophies, glaucoma, and retinoblastoma in order of frequency. Chromosomal aberrations were detected in two retinoblastoma cases and in one case of charge association with cataract and iris coloboma. A truncating mutation in exon 8 of OCRL1 was reported in a case of Lowe syndrome with cataract. A total of 51.7% of ocular cases were non-isolated (associated with other genetic disorders).

CONCLUSION: In Egypt, ocular genetic disorders are not uncommon among other genetic disorders. Consanguinity is high, suggesting high incidence of autosomal recessive inheritance of genetic disorders with an ocular component. Proper systemic assessment of all cases with ocular anomalies is a necessity due to the high percentage of non-isolated ocular anomalies. Genetic counseling of parents would help in reducing recurrence rates through prenatal diagnosis whenever possible.

Mahmoud, "Does bloody aspirate reflect the state of upper gastrointestinal mucosa in a critically ill newborn?", Arab journal of gastroenterology : the official publication of the Pan-Arab Association of Gastroenterology, vol. 13, issue 3, pp. 130-5, 2012 Sep. Abstract

BACKGROUND AND STUDY AIMS: Critically ill newborns have many risk factors to develop stress related mucosal lesions (SRML). We used upper endoscopy to evaluate the presence of SRML in these neonates, to know the specificity and sensitivity of the bloody gastric aspirate to detect SRML and to identify the risk factors associated with the presence of SRML and bloody gastric aspirate.

PATIENTS AND METHODS: This is a cross-sectional study done on 100 critically ill newborn after becoming clinically stable. SRML were diagnosed if there is hyperaemia, erosions or ulcers in the oesophagus, stomach, and/or the duodenum.

RESULTS: SRML were found in 77% of neonates in the NICU though frank bloody aspirate was detected in only 22% of neonates. The presence of bloody aspirate showed low sensitivity (24.68%) and high specificity (86.96%) for the presence of SRML. The presence of bloody gastric aspirate showed a double fold risk for the presence SRML (OR=2.184, CI=0.584-8.171). Factors associated with SRML included respiratory distress (p=0.000, risk=4.006), the use of nasogastric tube (p=0.017, OR=3.281) and the use of triple antibiotics (p=0.001, risk=1.432). Factors associated with the presence of bloody gastric aspirate included the use of nasogastric tube (OR=1.629, p=0.000) and the presence of haemostatic disorders (OR=3.143, p=0.039). It was also associated with lower haemoglobin levels (p=0.000).

CONCLUSION: SRML represents an under-diagnosed problem in NICUs. Absence of bloody gastric aspirate does not exclude the presence of SRML.
