Treatment of Acute Zonal Occult Outer Retinopathy With Intravitreal Steroids
Background And Objective:
To report on the use of intravitreal steroids in the management of acute zonal occult outer retinopathy (AZOOR), a rare disorder affecting the outer retina.
Patients And Methods:
Retrospective case series of nine eyes of five patients with AZOOR who received intravitreal triamcinolone acetonide (IVTA), dexamethasone intravitreal implant, and/or fluocinolone acetonide implant. Treatment response was determined by reported symptoms and multimodal imaging findings. Patients were observed for at least 1 year following intravitreal steroid treatment (range: 14 months to 63 months).
Results:
Seven eyes received IVTA, six eyes received the dexamethasone intravitreal implant, and one eye received the fluocinolone acetonide implant. All patients experienced disease stability or improvement based on symptomatic response and multimodal imaging findings after intravitreal steroids. One eye developed central serous retinopathy, and another eye a choroidal neovascular membrane. Five of nine eyes experienced ocular hypertension. All phakic eyes developed cataracts.
Conclusion:
Intravitreal steroids effectively achieved disease stability in patients with AZOOR. [Ophthalmic Surg Lasers Imaging Retina. 2018;49:504-509.].

Porin Insertion in the Outer Mitochondrial Membrane
Three models describe the assembly of porins by the SAM complex and their insertion into the outer membrane. Model 1 suggests that porins are assembled outside the SAM channel as the...
Protein Transport to the Outer Chloroplast Membrane
Two models describe the mechanism of precursor recognition and entry across the outer membrane through the TOC complex. Model 1 suggests the newly synthesized precursor binds to the TOC receptor 159 and forms a complex.
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
