Purpose: To investigate central corneal thickness (CCT) and intraocular pressure (IOP) relationship in eyes with and without previous corneal laser refractive surgery and to compare the estimates of two different tonometers-Goldmann applanation and pneumatonometer.
Methods: The study population included 234 glaucoma suspects who were referred to the glaucoma clinic with cup/disc ratios greater than 0.4, asymmetric cupping, and/or IOP greater than 22 mmHg during routine eye examination.

The surgical technique of endoscopic goniotomy (EG) using the anterior chamber maintainer (ACM) for congenital glaucoma is evaluated, and one-year follow-up data are presented. Endoscopic goniotomy was performed in 12 eyes of 7 patients. A double-port-special goniotomy knife mounted on the endoscope's probe inserted through the first incision and ACM through the second incision-EG technique was used in 6 eyes of 3 patients, while a three-port-knife, endoscope probe, and ACM inserted through separate incisions-technique was preferred in the remaining 6 eyes of 4 patients.
View Article and Find Full Text PDFPurpose: To investigate how optical coherence tomography (OCT) modifies the preset scan parameters to correct the errors resulting from ocular magnification, the influence of examiner's final correction of those already modified parameters on retinal nerve fiber layer (RNFL) thickness measurements, the induced change on RNFL thickness measurements and RNFL estimated integrals (RNFL(estimated integrals)) by adjusting the actual scan radius during RNFL examinations performed by OCT.
Methods: Thirty-five healthy patients underwent an RNFL examination by OCT four times using different scan radii. The first scan was performed with the preset circular scan diameter of 3.

Objective: Preservation of the supratrochlear vascular pedicle (SVP) during use of the paramedian forehead flap can be accomplished by the aid of Doppler imaging; however, a reliable surface landmark may be invaluable in cases where Doppler examination fails. Our observations showed that the most prominent glabellar frown lines (GFLs) are very close to the SVP; however, the actual relationship of these structures remains unclear.
Study Design: The relationship between GFLs and the SVP was investigated in 19 volunteers by the aid of Doppler imaging and in 8 cadaver heads by dissection.
