Does phacoemulsification under topical anesthesia affect retrobulbar blood flow?

Purpose: To investigate with color Doppler imaging the effects of phacoemulsification surgery under topical anesthesia on retrobulbar vessels hemodynamics.

Methods: In this prospective study, color Doppler imaging was used to measure the maximum (Vmax) and minimum flow velocity (Vmin) of the central retinal vein, and the Vmax and Vmin, pulsatility index and resistance index of the central retinal artery, nasal, and temporal posterior ciliary arteries, and ophthalmic artery blood flow before and 1 day after phacoemulsification surgery under topical anesthesia.

Results: After phacoemulsification surgery under topical anesthesia, Vmin of the central retinal artery increased (p ≤ 0.

Does ranibizumab (Lucentis®) change retrobulbar blood flow in patients with neovascular age-related macular degeneration?

Purpose: To investigate the effects of intravitreal ranibizumab on retrobulbar blood flow in patients with neovascular age-related macular degeneration (AMD).

Methods: Thirty-one eyes of 30 patients with neovascular AMD were examined prospectively by both color Doppler imaging and fundus fluorescein angiography. Color Doppler imaging was used to measure the maximum and minimum velocities of the central retinal vein, peak systolic/end-diastolic velocities of blood flows, and pulsatility index and resistivity index values in the central retinal artery, nasal/temporal posterior ciliary arteries (NPCA/TPCA) and ophthalmic artery.

Effects of intravitreal bevacizumab (Avastin) therapy on retrobulbar blood flow parameters in patients with neovascular age-related macular degeneration.

Background: To investigate the effects of intravitreal bevacizumab on retrobulbar circulation in patients with neovascular age-related macular degeneration (AMD).

Method: Thirty patients with neovascular age-related macular degeneration were assessed prospectively by both color Doppler imaging and fundus fluorescein angiography. Spectral Doppler analysis allowed the measurement of the maximum velocity (Vmax) and minimum velocity (Vmin) of the central retinal vein (CRV), and peak systolic (PSV), end-diastolic (EDV) velocities of blood flows, and pulsatility index (PI) and resistance index (RI) values in the central retinal artery (CRA), nasal and temporal posterior ciliary arteries (NPCA, TPCA), and ophthalmic artery (OA).

Ophthalmic manifestations of 107 cases with hemolysis, elevated liver enzymes and low platelet count syndrome.

Objective: To present various ophthalmologic disorders in a clinical series of hemolysis, elevated liver enzymes and low platelet count (HELLP) syndrome cases.

Methods: This is a prospective clinical study performed between 2002 and 2005. One hundred seven HELLP patients attended in either Departments of Ophthalmology or Obstetrics and Gynecology, Medical School, Gaziantep University, Gaziantep, Turkey were evaluated.

Sutureless closure of the conjunctiva with a commercial fibrin sealant in extraocular muscle surgery for strabismus.

Purpose: Suturing is a time-consuming process and patients may suffer from sutures because of discomfort and tearing. This prospective study was done to determine the efficacy of an available commercial fibrin sealant for conjunctival wound closure following extraocular muscle surgery for strabismus.

Methods: Fibrin sealant (Beriplast) was used in 48 conjunctival wounds of 25 patients with strabismus during the period February 2004 to May 2005.
