چکیده

PURPOSE To determine the presence of fluorescein leakage from the iris and angle in normal subjects, and how it is affected by aging. METHODS The subjects were 92 normal volunteers and patients with senile cataract who ranged in age from 20 to 93 years and were free from any systemic or ocular diseases. Fluorescein iris and angle photography and color iris and angle photography were performed using a goniolens and a photo slit lamp. RESULTS Radial ciliary body vessels were found in 22 eyes (24%), radial iris vessels or trabecular vessels in 7 eyes (8%), and circular ciliary band vessels were seen in 4 eyes (4%). Goniovessels were found in 8 of 30 eyes (27%) of those under 50 years of age. No significant difference in the incidence of goniovessels was found between those over and under age 50 (P < .01). In the pupillary margin, fluorescein leakage was seen in 1 of 30 eyes (3%) in the age group under 50 years, whereas leakage was found in 30 of 62 eyes (48%) in the age group over 50 years. In the anterior chamber angle, leakage was seen in 4 of 30 eyes (13%) under age 50 years, and in 38 of 62 eyes (61%) over age 50 years (P < .05). CONCLUSIONS These findings suggested that the incidence of leakage of fluorescein from the pupillary margin and anterior chamber angle tends to increase with age. Thus, when leakage of fluorescein in angle and iris is observed, it is important to consider the physiological changes resulting from aging.

Differentiation between CSF Otorrhea and Rhinorrhea in an Obscure Case of Recurrent Meningitis

Introduction: Leakage of cerebrospinal fluid in the skull base may be accompanied with recurrent meningitis. The site of leakage may either be anterior (in the nose and paranasal sinuses) or posterior (in the temporal bone). Various imaging techniques can be used to precisely locate the point of leakage but despite all the advances in imaging techniques there are still some rare cases in which ...

Gonioscopic Features in Patients with Acute and Chronic Angle-Closure Glaucoma

Background: A number of ocular biometric parameters, iris hiotologic and anatomic characters have been suggested as inciting factors for converting patients with narrow angle to angle-closure glaucoma. This study was conducted to determine if there was any goniscopic difference between patients with acute angle-closure glaucoma (AACG) and chronic angle-closure glaucoma (CACG). Methods: ...

Different References for Valgus Cut Angle in Total Knee Arthroplasty

Background: The valgus cut angle (VCA) of the distal femur in Total Knee Arthroplasty (TKA) is measured preoperativelyon three-joint alignment radiographs. The anatomical axis of the femur can be described as the anatomical axis of thefull length of the femur or as the anatomical axis of the distal half of the femur, which may result in different anglesin some cases. During TKA, the anatomical ...
