PURPOSE: To evaluate the feasibility and efficacy of mini-scleral design (MSD) contact lenses to treat keratoconus patients who were unsatisfied with the results of corneal inlay. METHODS: In this prospective interventional case series, 9 eyes of 6 keratoconus patients who were unsatisfied with the results of corneal inlay were fitted with MSD contact lenses. Demographic data, uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), and higher order aberrations (HOAs) were evaluated before contact lens fitting...

PURPOSE: To assess the effect of two silicone hydrogel contact lenses with high oxygen permeability in patients having photorefractive keratectomy (PRK). SETTING: Farabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran. METHODS: Sixty patients (120 eyes) who had bilateral PRK were enrolled in this double blind clinical trial. Each patient was fitted with a Lotrafilcon B (Air Optix(®)AQUA, Ciba Vision, Duluth, GA, USA) lens in one eye and a Balafilcon A (PureVision™ Bausch & Lomb, Rochester, NY, USA) lens in the fellow eye...

An anaerobic hybrid reactor (UASB/Filter) was used for petrochemical wastewater treatment in mesophilic conditions. The seeded flocculent sludge from a UASB plant treating dairy wastewater, acclimatized to the petrochemical wastes in a two-stage operation. After start up, under steady-state conditions, experiments were conducted at OLRs of between 0.5 and 24 kg TCOD m(-3) d(-1), hydraulic retention times (HRT) of 4-48 h and up-flow velocities 0.021-0.25 mh(-1). Removal efficiencies in the range of 42-86% were achieved at feed TCOD concentrations of 1,000-4,000 mg L(-1)...

BACKGROUND: To compare the effect of different dosages of subconjunctival bevacizumab with its topical administration on preventing the development of corneal neovascularization (CNV) in a rat model of corneal chemical injury. METHODS: Neovascularization was induced by pressing a 2-mm diameter alkaline-coated applicator on the central cornea of the right eye of 50 anesthetized male rats. Immediately after cauterization, rats were divided randomly into 5 groups. Groups 1-4 received a subconjunctival injection of 0...

Despite the successful application of sentinel node mapping in breast cancer patients, its use in patients with a history of previous excisional biopsy of the breast tumors is a matter of controversy. In the present study we evaluated the accuracy of sentinel node biopsy in this group of patients and compared the results with those in whom the diagnosis of breast cancer was established by core needle biopsy. Eighty patients with early stage breast carcinoma were included into our study. Forty patients had a history of previous excisional biopsy and the remainder 40 had undergone core needle biopsy...

PURPOSE: To evaluate the efficacy of intralesional bevacizumab injection in decreasing size of pterygium. METHODS: Seventeen patients with pterygium (14 with primary and 3 with recurrent pterygium) received intralesional injections of bevacizumab (2.5 mg/0.1 mL). Digital photographs were analyzed by image analysis software to determine the change of corneal involvement as a percentage of the total corneal surface. RESULTS: The mean age of the patients was 45...

PURPOSE: To report the effect of intrastromal injection of bevacizumab in an eye with extensive corneal stromal vascularization after deep anterior lamellar keratoplasty. METHODS: Bevacizumab (2.5 mg/1 mL) was injected into the deep corneal stroma of an eye with severe and extensive stromal vascularization. RESULTS: Corneal vascularization regressed dramatically after deep stromal injection of bevacizumab with no recurrence after 6 months...

OBJECTIVE: We compared early and delayed lymphoscintigraphy images using intradermal injection of (99m)Tc-antimony sulfide colloid, which has small particles. METHODS: Eighty patients with early-stage breast cancer were included into the study. Intradermal injection of (99m)Tc-antimony sulfide colloid was used for sentinel node mapping. After radiotracer injection, 30 min and 20 h later, lymphoscitigraphy images were obtained in lateral and anterior views. After the completion of each image sets, the location of the visible nodes in the axilla was marked on the skin...

BACKGROUND: To evaluate and compare the effect of different doses of subconjunctival bevacizumab with betamethasone on the development of corneal major new vessels in a rat model of corneal chemical injury. METHODS: The right eyes of 100 male Sprague-Dawley rats were randomly divided into 10 experimental groups (n = 10 per group). Chemical cauterization of the cornea was performed by using silver nitrate/potassium nitrate sticks. Immediately following corneal cauterization, the animals in groups 1-5 received subconjunctival injections of 0...

BACKGROUND: This study was conducted to determine the treatment outcome of incompletely removed, histopathologically documented ocular surface squamous neoplasia with mitomycin-C. METHODS: Through an interventional case series, 17 eyes of 17 patients presented with incompletely removed ocular surface squamous neoplasia were treated according to a protocol using two to three alternate seven-day courses of 0.04% mitomycin-C. Clinical recurrence was re-treated with the same protocol...
