Introduction: Pterygium surgery is a closed globe surface surgery. Although it is perfectly standard and followed by excellent results, it is not exempt from the general rule that there is no surgery without risk. It therefore seems important to integrate simulation as a pedagogical tool for training ophthalmology residents in pterygium surgery.

Hypopyon: Is-it Infective or Noninfective?

Hypopyon usually corresponds to the sedimentation of white blood cells, and it signifies severe intraocular inflammation. This key clinical sign may occur in association with a wide variety of infectious, inflammatory, and neoplastic conditions that may be sight- and, occasionally, life-threatening. A careful history and thorough clinical examination are the cornerstones for orienting the differential diagnosis, identifying the causative agent, and initiating prompt and appropriate treatment.

Graves' Orbitopathy: Report of 82 cases.

Introduction: Graves' disease (GD) is a common autoimmune disorder. Graves'orbitopathy (GO) is its most common extrathyroidal manifestation. It is rare but may reveal the disease.

The contribution of simulation in training for funduscopic examination.

Introduction: Simulation is emerging as an essential part of health sciences training programs as it provides safer patient care by reducing the risk of error. In the healthcare environment, simulation continues to spread in emergency specialties, but it is still underdeveloped in ophthalmology and there is a shortage of publications on this subject in Tunisia.

Objective: To evaluate the effectiveness of procedural simulation as a teaching tool for funduscopic examination training.

Assessment of facility performance during mass treatment of chronic hepatitis C in Egypt: Enablers and obstacles.

Background: The national committee for control of viral hepatitis (NCCVH) in Egypt, settled by the Ministry of health, treated over one million patients in around 60 centers with chronological changes in drug combinations. This research aims to study the health care facilities and services provided by NCCVH treatment centers in Egypt and explore hinders faced.

Methods: A cross-sectional operational research study.

To evaluate the clinical improvement in ocular symptoms and signs in patients suffering from anterior blepharitis after using a novel cleansing wipe impregnated with 2.5% terpinen-4-ol and 0.2% hyaluronic acid.

Bilateral acute angle-closure glaucoma following tramadol subcutaneous administration.

Background: To report a case of bilateral acute angle closure-glaucoma following the use of subcutaneous Tramadol.

Case Presentation: A 42-year-old healthy man with unremarkable past medical and ocular history, was admitted to the Orthopedic Department for surgical treatment of a bilateral open fracture of the femur following a road accident. Three hoursafterTramadolsubcutaneous injection, the patient complained of a bilateral acute painful visual loss with persistent vomiting.

Anterior segment optical coherence tomography and retained vegetal intraocular foreign body masquerading as chronic anterior uveitis.

Background: The purpose of this single case report was to report the use of anterior segment optical coherence tomography for the diagnosis and management of a retained vegetal intraocular foreign body.

Infectious optic neuropathies: a clinical update.

Different forms of optic neuropathy causing visual impairment of varying severity have been reported in association with a wide variety of infectious agents. Proper clinical diagnosis of any of these infectious conditions is based on epidemiological data, history, systemic symptoms and signs, and the pattern of ocular findings. Diagnosis is confirmed by serologic testing and polymerase chain reaction in selected cases.

Acute retinal periphlebitis mimicking frosted branch angiitis associated with exudative retinal detachment after blunt eye trauma.

We report a case of a 14-year-old otherwise healthy patient who developed acute retinal periphlebitis mimicking frosted branch angiitis inferotemporally and associated exudative retinal detachment in the left eye following blunt trauma. Fluorescein angiography revealed delayed filling of inferotemporal branch retinal vein and late leakage of sheathed retinal venules, and late pooling in the area of exudative retinal detachment. Indocyanine green angiography showed a crescent-shaped hypofluorescent streak concentric to the optic disk inferiorly highly suggestive of choroidal rupture.

Hepatitis C virus induced insulin resistance impairs response to anti viral therapy.

Hepatitis C virus (HCV) infection is an important risk factor for insulin resistance (IR). The latter is the pathogenic foundation underlying metabolic syndrome, steatosis and cirrhosis, and possibly hepatocellular carcinoma (HCC). The interplay between genetic and environmental risk factors ultimately leads to the development of IR.
