Setting: Sixteen-bed, general ICU at a tertiary academic medical center.
Age-related macular degeneration is the leading cause of blindness and visual impairment in the developed world. The recently introduced anti-vascular endothelial growth factor (VEGF) intravitreal injections of Ranibizumab (Lucentis) and Bevacizumab (Avastin) generated a heated academic argument: on the one hand Lucentis is the only drug that was proven effective and relatively safe in large prospective double-blinded studies, albeit this drug is expensive and might cost up to $1000 per single injection. On the other hand, Avastin is widely used worldwide as a low cost alternative for Lucentis, with an estimated cost of about $120 per injection, although its efficacy and side effects were investigated only in smaller retrospective studies.

Methods: Ninety-two digital FAs demonstrating subfoveal CNV secondary to AMD were evaluated independently by five retina specialists. The pattern of classic component could be classified as no classic component, minimally classic, predominantly classic, or classic only.
Purpose: To evaluate the visual outcome of patients with myopic subfoveal choroidal neovascularization (CNV) given photodynamic therapy (PDT) in a clinical setting, and to identify potential relation between the visual outcome and the age at treatment.
Design: Interventional case series.
Methods: Retrospective comparative study.
Objective: To examine the reliability of Swedish Interactive Thresholding Algorithm Fast (SITA Fast) visual fields (VFs) in prepubertal idiopathic intracranial hypertension (IIH) and to compare whether age, gender, or severity of visual outcome influenced the reliability of VF tests.
Design: Prospective, longitudinal cohort study.
Participants: Twenty-six prepubertal children (<11 years of age; mean age, 7.
Objective: To study the visual and angiographic outcome of eyes with neovascular age-related macular degeneration associated with pigment epithelium detachment (PED) treated by photodynamic therapy.
Methods: Review of the medical charts and the fluorescein and indocyanine green angiograms of all consecutive patients with age-related macular degeneration associated with choroidal neovascularization and serous PED of at least 1 disc diameter, who received photodynamic therapy from January 1, 2000, to August 31, 2002.
Results: Thirty patients (34 eyes) met the study criteria.
Purpose: To evaluate the visual outcome of patients with subfoveal choroidal neovascularization due to age-related macular degeneration, who received photodynamic therapy (PTD) in a clinical setting and to identify potential predictive visual and angiographic factors.
Design: Interventional case series.
Methods: The study included 74 patients with subfoveal choroidal neovascularization who underwent PDT from January 2000 to March 2001 and completed at least 1 year follow-up.
Background And Objective: The aim of this study was to investigate the effect of interferon alpha-2a, an angiogenesis inhibitor, on eyes with active neovascularization after complete laser panretinal photocoagulation treatment.
Patients And Methods: Eight patients with active neovascularization persisting for 6 months or more after completion of full panretinal photocoagulation were included in the study. All patients were treated with subcutaneous injections of 6 million international units of interferon alpha-2a, 3 times a week, for an average period of 10 months.
Purpose: To investigate a method that uses hyperacuity, the Macular Computerized Psychophysical Test (MCPT), to evaluate the central macular visual field in patients with age-related macular degeneration (AMD).
Design: Prospective case-control study of a diagnostic test.
Participants And Controls: One hundred eight eyes of 108 Patients with AMD and 51 eyes of 51 age-matched patients with no retinal disease.
Objective: To identify the angiographic features of retinal choroidal anastomoses (RCAs) in patients with newly diagnosed occult choroidal neovascularization (CNV) in the setting of age-related macular degeneration (AMD) and to determine the sequence of flow between the RCA and the CNV.
Design: Retrospective cross-sectional study.
Participants: The angiograms of 205 eyes of 153 consecutive patients with occult CNV on fluorescein angiography (FA) and focal hot spots on indocyanine green angiography (ICGA) were evaluated retrospectively.
Article Synopsis
- The study aimed to assess changes in retinal blood vessels over pigment epithelial detachments (PED) in patients with exudative age-related macular degeneration (ARMD) using specialized imaging techniques.
- Out of 41 patients examined, significantly more vascular abnormalities were detected with indocyanine green angiography compared to fluorescein angiography, indicating its greater sensitivity.
- A correlation was found between retinal vasculopathy, choroidal neovascularizations, and the size of the PED, suggesting potential implications for understanding disease progression in ARMD.
Pigmentary dispersion syndrome is a precursor of pigmentary glaucoma whose prevalence in the urban population of USA was found to be 2.45%. We evaluated its prevalence during ocular screening examinations among normal Israelis.

Objectives: To assess the quantitative relation between pterygium size and induced corneal astigmatism using a computerized corneal analysis system (TMS II) and slit-lamp beam evaluation of pterygium size, and to conclude whether corneal astigmatism is an early indication for surgical intervention.
Methods: We evaluated 94 eyes of 94 patients with unilateral primary pterygium of different sizes, using TMS II and slit-lamp beam measurements of the size of the pterygium (in millimeters) from the limbus to assess parameters of pterygium size with induced corneal astigmatism.
Of the world population, 38 million are blind and another 110 million are visually impaired. Even in the developed countries there are 3.5 million who are blind.

Methods: Videokeratography was performed in 36 patients (72 eyes) with an echocardiographic diagnosis of MVP, and were compared with 25 controls. All participants underwent slit-lamp examination and completed a medical questionnaire about joint hypermobility, arthralgia, asthma, and allergic reactions.
Purpose: To compare fluorescein angiography and indocyanine green angiography for imaging of choroidal neovascularization located under subretinal hemorrhage, in age-related macular degeneration.
Methods: In a retrospective study, 30 eyes of 30 consecutive patients with hemorrhagic age-related macular degeneration were evaluated with fluorescein angiography and indocyanine green angiography. In each eye, areas of macular hemorrhage, choroidal neovascularization, and total lesion (hemorrhage plus choroidal neovascularization) were measured, and the choroidal neovascularization was categorized as classic, occult, or mixed on fluorescein angiography, and as hot spot, plaque, or combined lesion on indocyanine green angiography.
