Background: In recent years, major progress has been made in treating the wet form of age-related macular degeneration (AMD) with anti-vascular endothelial growth factors, which reportedly stabilize and improve vision.

Objectives: To examine the effect of dietary supplementation, as recommended by the Age-Related Eye Disease Study 2 (AREDS2), on the number of anti-vascular endothelial growth factor injections administered to patients with wet AMD.

Methods: A retrospective study was conducted with 57 participants (27 participants in the study group and 30 in the control group) receiving injections of anti-vascular endothelial growth factors. The study group received dietary supplements for at least one year before the treatment was initiated, while the control group did not. Primary outcome was the number of injections a patient received over a 3-year period. Secondary outcomes were central macular thickness and visual acuity.

Results: The average number of injections per patient after 3 years was 21.89 ± 7.85 in the study group and 26.00 ± 5.62 in the control group (P = 0.083). Final visual acuities were 0.45 ± 0.45 and 0.8 ± 0.73 (P = 0.09), and final central macular thicknesses were 288.26 ± 55.38 and 313.12 ± 107.36 (P = 0.38) in the study and control groups, respectively.

Conclusions: The average number of injections after 3 years was lower in the study group, but this difference did not reach statistical significance. No statistically significant difference was found in final visual acuity or central macular thickness between the groups.

Background: Vitamin D deficiency and insufficiency have been reported in fibromyalgia. However, to the best of our knowledge, only one study has evaluated the role of 25-hydroxyvitamin D [25(OH)D] supplementation on fibromyalgia symptoms.

Objectives: To analyze the effects of 3 months of 25(OH)D supplementation on symptoms of fibromyalgia.

Methods: This study included 11 female patient. Demographic and clinical data, tender points, visual analog scale results, and pre- and post-serum levels of 25(OH)D supplementation were analyzed. The levels of 25(OH)D were measured by a radioimmunologic test.

Results: Patients with fibromyalgia diagnosis and 25(OH)D values ≤ 30 ng/ml were recruited to receive 50,000 IU of oral vitamin D once every week for 3 months. The disease was diagnosed based on the American College of Rheumatology criteria. The median age of all patients was 48.5 (28–67) years and 63.4% were Caucasian. Disease duration varied from 1–10 years. The 25(OH)D levels increased significantly after 3 months, 18.4 (15.5–25.8) ng/ml vs. 33.8 (28–58) ng/ml, P = 0.01. Interestingly, an improvement of visual analog scale scores was observed at 3 months, 90 (0–100) vs. 30 (0–80), P = 0.002. Eight patients (72.2%) responded that they experienced a very significant improvement in symptoms. In addition, a trend for reduction of the number of tender points was observed after 3 months, 17 (11–18) vs. 10 (0–18), P = 0.07.

Conclusions: The 25(OH)D levels and disease symptoms in patients with fibromyalgia and vitamin D deficiency/insufficiency seem to improve with vitamin D supplementation.

Background: Pain, fatigue and functional disability are common key outcomes in most rheumatologic disorders. While many studies have assessed the outcomes of specific disease states, few have compared the outcomes of various rheumatic diseases.

Objectives: To assess how the intensity and rating of pain, fatigue and functional disability vary among groups of patients with various rheumatic disorders receiving standard care. 

Methods: In a cross-sectional study conducted in a hospital-based rheumatology unit, standard clinical and laboratory data were obtained and all patients filled out questionnaires on pain, fatigue and daily function. The analysis concentrated on visual analogue scales (VAS) using specific statistical methods.

Results: A total of 618 visits of 383 patients with inflammatory as well as non-inflammatory rheumatic disorders were analyzed. Fibromyalgia patients had significantly higher VAS scores compared to all other groups. On the other hand, patients with polymyalgia rheumatica demonstrated significantly lower VAS scores compared to all other groups of patients. Patients with psoriatic arthritis also demonstrated relatively low VAS scores. VAS scores were lower in patients with inflammatory disorders as compared to patients with non-inflammatory disorders.

Conclusions: Our results suggest a spectrum of outcome intensity in various rheumatic disorders receiving standard care, ranging from fibromyalgia patients who report distinctive severity to patients with inflammatory disorders who are doing relatively well as compared to patients with non-inflammatory disorders. The findings emphasize the need to explore the underlying mechanisms of pain and fatigue in patients with non-inflammatory rheumatic disorders. 

 

Objectives: To describe and identify clinical characteristics, prognostic factors and visual outcome in a group of patients with OGI in southern Israel.

Methods: We conducted a retrospective review of all cases of OGI examined in the ophthalmology department at Soroka University Medical Center, Beer Sheva, Israel, from 1996 to 2005. A total of 118 eyes with OGI were detected and analyzed statistically. We recorded demographic data, cause of injury, initial visual acuity (VA), associated globe morbidity and injuries, Ocular Trauma Score (OTS), surgical procedures, postoperative complications, and final VA.

Results: The mean age of the study group was 36.1 years and included 84% males. The median follow-up was 13.3 months (range 6–66 months). The annual incidence of open globe injuries was 3.1 cases/100,000. In 84 cases (71%) the mechanism of open eye injury was laceration. Most of the injuries were work related (45%). Bilateral injury was observed in two patients. An intraocular foreign body was observed in 45 eyes (38%). Primary surgical repair was performed in 114 eyes. Six patients (5.1%) had complications with post-traumatic endophthalmitis and 12 patients (10.1%) underwent evisceration or enucleation. Clinical signs associated with poor visual outcomes included reduced initial VA, eyelid injury, and retinal detachment at presentation.

Conclusions: In our study population the most important prognostic factors in open globe injury were initial VA, eyelid injury and retinal detachment.

Background: Delayed diagnosis of choroidal neovascularization (CNV) in age-related macular degeneration (AMD) adversely affects visual outcome.

Objectives: To identify factors associated with early detection of CNV in the clinic setting.

Methods: Demographic and clinical data and lesion characteristics were retrospectively collected from 76 consecutive AMD patients who had a history of CNV in one eye and presented with CNV in the second eye. These data were evaluated for association with visual acuity (VA) at the time of presentation.

Results: Better VA was associated with a history of CNV in the fellow eye (P < 0.0001), adherence to follow-up every 4 months (P = 0.015), younger age (P = 0.03), smaller lesion (P < 0.0001), and non-subfoveal location (P = 0.048). VA of the fellow eye did not correlate with VA at presentation with CNV.

Conclusions: These data suggest that patients’ experience of CNV, regardless of VA, facilitates early diagnosis in the fellow eye. Adherence to follow-up in the routine clinic setting also facilitates early detection of CNV.

Background: Pediatric functional visual loss (FVL) is the loss of vision in a child that cannot be explained by an organic pathology. In the last decade, only a few studies on pediatric FVL have reported long-term patient follow-up.

Objectives: To report the characteristics of pediatric FVL with long-term follow-up in Israeli children.

Methods: We conducted a retrospective chart review of the medical records of patients with FVL from 2000 to 2010. Only children with adequate follow-up (at least 2 months) were included.

Results: Of the 12 patients identified, 9 were females. Mean patient age was 10.5 ± 4.4 years (range 3.5–17 years). Most children (75%) had bilateral visual loss. One patient had a history of psychiatric illness and in three patients a preceding psychosocial event/trauma was identified. Brain imaging and electrophysiology testing (if done) were normal in all cases. No medications were prescribed to any of the patients, and all were reassured that there was a high chance of spontaneous resolution. The follow-up time was 2–108 months (mean 23.8 months, median 6). During the follow-up period 9 of the 12 had complete resolution and 2 had relief of symptoms. Three patients reported a recurrence of symptoms. No organic disease was ever diagnosed in this group.

Conclusions: FVL may occur in all age groups, including children. In cases of visual loss, it is usually bilateral and can involve both acuity and visual field loss. In the present report most of the patients experienced normalization or relief of their symptoms without medical treatment.
 

Background: The European Quality of Life 5-Dimensions questionnaire is one of the most commonly used measures of health-related quality of life.

Objectives: To present the feasibility, reliability, and validity of the Hebrew version of the EQ-5D[1].

Methods: We conducted face-to-face interviews with a representative sample (n=1666) of the Israeli Jewish population. The data collected included demographic and medical information, and self-valuation of health using the EQ-5D descriptive system, Visual Analogue Scale and Time Trade-Off. Construct validity was assessed by assuming that older individuals, those with a greater burden of diseases, and those reporting experience with their own severe illness would have lower EQ-5D indexes, VAS[2] and TTO[3] values. Test-retest reliability was assessed in a small sample (n=50) that was reevaluated after a 3 week interval.

Results: Test-retest reliability of the EQ-5D and VAS was very high (r ≥ 0.85). Reliability of the TTO was moderate (r = 0.48). There were significant differences in the EQ-5D index, profiles, VAS and TTO between healthy and sick respondents and younger and older respondents, indicating good validity of the instrument.

Conclusions: The Hebrew translation of the EQ-5D is a practical, reliable and valid instrument for assessing the health-related quality of life of the general Israeli Jewish population.

Background: The American Academy of Pediatrics recently published recommendations for the red reflex assessment in the newborn period to detect and treat ocular disorders as early as possible, and to prevent lifelong visual impairment and even save lives. The test is technically simple to perform, non-invasive, requires minimal equipment and can detect a variety of ocular pathologies including cataracts and retinal abnormalities. No specific national guidelines exist on this issue.

Objectives: To document the implementation of red reflex examination in routine neonatal care and present the findings.

Methods: Our clinical experience following implementation of the red reflex test into the newborn physical examination in a single center was reviewed. In addition, an electronic mail questionnaire was sent to all neonatology departments in Israel regarding the performance of the red reflex test.

Results: During 2007–2008, five infants were identified with congenital cataracts at days 2–6 of life prior to discharge from hospital. Surgery was performed in one infant at age 2 months and all infants underwent a thorough follow-up. The incidence of congenital cataract in our center was 1:2300. Less than half the neonatology departments have endorsed the AAP[1] recommendation and perform the red reflex test routinely.

Conclusions: Abnormal red reflex test after delivery enables a rapid ophthalmologic diagnosis, intervention and close follow-up. We recommend that red reflex screening be performed as part of the newborn physical examination if abnormal, an urgent ophthalmologic referral should be made.

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 for 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.

Methods: A retrospective review of the annual report of the National Registry for the Blind in Israel between 1998 and 2003 identified 21,585 blind persons who received a certificate for blindness. Blind persons are identified by ophthalmologists throughout Israel and referred to the Registry of the Blind if they have a visual acuity of 3/60 or worse, or a visual field loss of < 20 degrees in their better eye. This report includes prevalence data on 21,585 persons enrolled in this review still alive and living in Israel in 2003. We estimated the prevalence rate of blindness nationwide and the incidence rate for each cause of blindness for every year.

Results: The main leading causes of blindness in Israel in 1998 were (in percent of the total number of newly registered patients): age-related macular degeneration (20.1%), glaucoma (13.8%), myopic maculopathy (12%), cataract (10.4%), diabetic retinopathy and maculopathy (10.1%), and optic atrophy (7.9%), and in 2003, 28%, 11.8%, 7.4%, 6.5%, 14.4% and 6.5% respectively.

Conclusions: The results indicate that the incidence of age-related macular degeneration, diabetic retinopathy and maculopathy in Israel is increasing, while that of glaucoma, myopic maculopthy, optic atrophy and cataract is decreasing.
