Afforestation is an important approach to mitigate global warming. Its complex interactions with the climate system, however, makes it controversial. Afforestation is expected to be effective in the tropics where biogeochemical and biogeophysical effects act in concert; however, its potential in the large semi-arid regions remains insufficiently explored.

Methods: A single-center retrospective observational case-control design was used. The sample consisted of 15 patients (mean age 60.
Purpose: To determine if the timing of mitomycin C (MMC) application during pterygium surgery affects endothelial cell loss.
Methods: A retrospective, nonrandomized, case-series design was used. The study group included 40 patients who underwent pterygium surgery with the bare sclera technique.
The authors report on a case of bilateral pterygia that the Israeli Social Security Service acknowledged to be an occupational disease. The question of whether certain occupations are risk factors for pterygia has important medico-legal implications. The authors sought to shed more light on this issue through a case report of bilateral simultaneous pterygia in an Israeli tennis instructor and through a literature review.

Case Presentation: A 15-year-old boy presented with long-term ocular symptoms of foreign body sensation, burning, irritation, tearing, and transient photophobia. One year's treatment with steroidal agents had led to only partial improvement.
Purpose: To evaluate changes in endothelial cell count after pterygium surgery with 5-minute application of mitomycin C (MMC) 0.02%.
Methods: The study participants included 24 consecutive patients (17 men and 7 women) who underwent pterygium surgery with MMC at a major tertiary center between September and October 2005.
Purpose: To evaluate the effect of dexamethasone eyedrops on blood glucose.
Methods: Two hundred eighty-five patients who underwent cataract surgery were prospectively randomized to receive treatment with topical dexamethasone or diclofenac for 1 month. A capillary blood sample was collected before surgery, immediately after, 1 week later, and 1 month later.
Purpose: To compare the long-term results of conjunctival closure with fibrin adhesive or Vicryl sutures in pterygium surgery.
Methods: The study was performed in 81 patients (81 eyes) with primary nasal pterygium. Surgery in all patients consisted of the bare sclera technique combined with intraoperative administration of mitomycin C 0.
Background: The prevalence and incidence of blindness in Israel appear to be comparable to other western countries. Comparisons are difficult because of different definitions of blindness, and the uniqueness of the Israeli Registry of the Blind.
Objective: To characterize the population who were registered as Blind in Israel in the years 1998-2003 and estimate the prevalence and incidence of blindness by age and causes of blindness.
Purpose: To compare the short-term results of conjunctival closure in pterygium surgery using fibrin adhesive versus Vicryl sutures with respect to operative time, postoperative ocular signs and symptoms, and overall patient satisfaction.
Methods: A comparative prospective randomized clinical trial was performed in 65 patients (65 eyes) with primary nasal pterygium. Surgery in all patients consisted of the bare sclera technique combined with intraoperative mitomycin C.
Background: Studies conducted to date on the distribution density of goblet cells and epithelial cell morphology in pterygium have yielded contradictory findings.
Objective: To evaluate the density of goblet cells in pterygium and possible correlation between clinical and demographic features and goblet cell distribution.
Methods: The methodology involved retrospective case series.
Purpose: To describe the outcome of the use of fibrin adhesive (Quixil) in penetrating trabeculectomy in a rabbit model.
Methods: Fibrin adhesive was used experimentally to attach the conjunctiva and the scleral flap in two groups of 17 New Zealand albino adult rabbits (34 eyes). In the first experiment (20 eyes), the fibrin adhesive was used to reattach the tissue after conjunctival peritomy and scleral flap only in 14 eyes (experiment I).
Purpose: To evaluate the safety and efficacy of a preoperative injection of mitomycin C (MMC) in combined pterygium and cataract surgery.
Methods: This was a prospective, nonrandomized, interventional trial. Thirty-nine patients with cataract and pterygium enrolled in a prospective, nonrandomized trial.
Objective: To evaluate the effect of pterygium surgery on the corneal topography and visual acuity and to correlate the results with patients' features.
Methods: A prospective, nonrandomized, self-controlled trial. Computerized videokeratography was performed in 54 patients (55 eyes) with primary pterygium before and after pterygium excision using bare sclera technique combined with intraoperative mitomycin C.
Aim: To evaluate the relation between postconceptional age and birth weight with keratometric values in preterm and full term infants.
Methods: A prospective cross sectional study was performed. The cohort included 99 infants (198 eyes) admitted to the Neonatal and Neonatal Intensive Care Units at Schneider Children's Medical Center of Israel from February to September 2002.
Purpose: To evaluate the effect of covering the sclera with conjunctiva during surgical treatment of pterygium on the rate of postoperative complications, cosmetic outcome, and risk of recurrence.
Methods: A comparative, prospective clinical design was used. The study population consisted of 371 consecutive patients with unilateral primary advanced pterygium.
Purpose: To evaluate the postoperative outcome and recurrence rate of bare sclera technique combined with intraoperative application of mitomycin C (MMC) 0.02% for 5 minutes in the treatment of primary and recurrent double-head pterygia.
Methods: A prospective, noncomparative interventional case series of 13 eyes in 13 patients with primary (n = 10) or recurrent double-head pterygia in one eye operated on by one surgeon (R.
This study of the causes of blindness in Israel in the year 2000 is based on the National Registry of the Blind in Israel. Patients are considered blind if they have a visual acuity of 1/60 or worse, in their better eye, or visual field loss of > 20 degree, in their better eye. At the end of 1998, 15,937 were registered as blind, 2.
View Article and Find Full Text PDFPurpose: To compare the effect of a 3- and 5-minute intraoperative application of topical mitomycin C 0.02% on the recurrence of pterygium.
Methods: A comparative, prospective clinical design was used.
Background: Many ophthalmologists instruct patients with glaucoma to avoid coffee, although data supporting this practice are insufficient.
Objective: To estimate the effect of drinking coffee on intraocular pressure (IOP).
Methods: In this crossover study, the effect of the consumption of regular (180 mg caffeine in 200 mL beverage) and decaffeinated coffee (3.
Background: The time to recurrence after surgical removal of primary pterygium (pterygium) and the association between the rate of recurrence and the postoperative interval remain unclear.
Objectives: To determine the amount of follow-up time needed to identify recurrence in patients after surgical removal of pterygium.
Methods: We reviewed the files of 143 patients (143 eyes) with recurrent pterygium to determine the interval from surgery to recurrence.
