Myopia is one of the main risk factors for the onset of open-angle glaucoma. One of the first steps to assess glaucoma occurrence is the measurement of the intraocular pressure (IOP) by the Goldmann applanation tonometry (GAT). Even if this device is considered to be the gold standard for such measurements, it is affected by several sources of errors. Among these, there are the corneal thickness and curvature, both modified by corneal refractive surgery (CRS), that nowadays has become a very popular method to treat refractive errors. Indeed, CRS, by modifying the corneal shape and structure, causes an underestimation of the IOP measurements. In the literature, several IOP correction formulas to utilize with different devices have been proposed to overcome this problem. This paper aims to review the various correction formulas applied to the GAT in the attempt to improve the reliability of this measurement.
Patients and physicians are often pleased when uncorrected visual acuity (UCVA) on post-operative day 1 (POD1) after cataract surgery is 20/20. Unfortunately, this UCVA does not always last. This article aims to investigate the relationship between excellent uncorrected visual acuity on post-operative day 1 and final post-operative UCVA after uncomplicated cataract surgery.

The medical records of patients who had undergone uncomplicated cataract surgery between 2012 and 2017 were assessed. UCVA on POD1 and final UCVA were obtained for patients who had a final best-corrected visual acuity of 20/20 or better.

Of 309 patients with UCVA of 20/20 on POD 1, 62.4% maintained 20/20 and 87.4% maintained 20/25 or better as their final uncorrected visual outcome. Of 204 patients with UCVA of 20/25 on POD 1, 44.1% achieved 20/20 and 69.6% maintained 20/25 or better as their final uncorrected visual outcome. Patients with 20/20 UCVA on POD1 were more likely to have a better final UCVA compared with those who were 20/25 on POD1. Of the 531 patients with UCVA of 20/25 or better on POD1, 20% had final UCVA worse than 20/25 with 4% losing more than 2 lines for their final UCVA.

The majority of patients with 20/20 UCVA on POD1 after cataract surgery maintained excellent UCVA as their final visual outcome. However, a significant percentage of these patients experienced a decrease in UCVA over the course of the postoperative period.

To analyze the top 100 most-cited papers on pars intravitreal injections.

Literature search using the bibliographic databases of the ISI Web of Knowledge for all types of publications on intravitreal injections published between 1965 and 2019 in peer-reviewed journals.

Eighty-three of the top 100 papers on intravitreal injections were published in ophthalmology journals, their majority in the top five Q1 leading journals in the field. They originated from 16 different countries, predominantly from the USA (n=52), and were all published in English. These manuscripts cover a wide spectrum of topics but were mostly focused on retinal diseases (n=60) and the use of anti-VEGF or steroid agents (n=75).

This bibliographic study provides a unique perspective on the evolution and assimilation of intravitreal injections, from their introduction, through their present role as the most common therapeutic procedure in ophthalmology, to future developments.

Cyclosporine ophthalmic solution 0.09% (CsA 0.09% sol) is approved to increase tear production in patients with keratoconjunctivitis sicca. This study evaluated the efficacy of CsA 0.09% sol vs cyclosporine ophthalmic emulsion 0.05% (CsA 0.05% eml) vs ciclosporin ophthalmic emulsion 0.1% (CsA 0.1% eml) in a NOD mice model.

Mice were randomized and administered placebo, CsA 0.09% sol twice daily, CsA 0.05% eml twice daily, CsA 0.09% sol once daily, or CsA 0.1% eml once daily in the conjunctival sac of both eyes for 60 days. Tear volume was measured with phenol red threads at baseline and 4 hours after treatment every 15 days. selleck chemicals On day 58, the corneal surface was observed under a slit-lamp after staining with 3% lissamine green administered into the inferior lateral conjunctival sac. On day 61, mice were euthanized, globes excised, sliced into 4 µm sections in 3 areas per section, and stained. Total number of stained goblet cell/µm was counted, and the sum per eye was averaged. Lacrimal gland tissues were removed and interleukin (IL) 1-β cytokine levels estimated.

Groups comprised 11 mice each, including an untreated normal and untreated diseased control group (7 groups total). CsA 0.09% sol twice daily significantly increased tear volume on day 30, 45, and 60 vs CsA 0.05% eml (
<0.05, <0.001, <0.001, respectively) and vs CsA 0.1% eml on day 60 (
<0.05); CsA 0.09% sol once daily significantly increased tear volume on day 45 vs CsA 0.05% eml (
<0.05). Goblet cell density significantly increased with CsA 0.09% sol twice daily vs placebo and NOD control (
<0.01 both). There was no significant difference in corneal staining and IL-1β levels with CsA 0.09% sol.

Sixty-day treatment with CsA 0.09% sol showed comparatively improved preclinical results vs CsA 0.05% eml and CsA 0.1% eml.

To investigate the safety and tolerability of the multi-pressure dial (MPD) worn overnight for seven consecutive days.

Prospective, open-label, randomized, single-site study.

Twenty eyes of 10 subjects with open-angle glaucoma were fitted with an MPD and randomized to negative pressure application of -10 mmHg in one eye (study eye) worn overnight for 7 consecutive days.

Safety measures included best-corrected visual acuity (BCVA), intraocular pressure (IOP) changes from baseline during and after negative pressure application, slit lamp and dilated fundus exam findings, and rate of adverse events. Subjective assessments were completed daily by the subjects during the 7-day study period and immediately following the study period.

Prior to the 7-day testing period, application of 10 mmHg negative pressure reduced mean IOP from 18.2 ± 3.8 mmHg to 14.0 ± 2.1 mmHg (p<0.01), a 22% reduction. After 7 days of consecutive nightly wear, repeat IOP measurements with the application of negative pressure showed a decrease in mean IOP from 16.9 ± 4.3 mmHg to 13.5 ± 3.7 mmHg. The observed IOP reduction was in addition to the subjects' current treatment regimen. There were no statistically significant changes in IOP, BCVA from baseline following the 7-day period of nightly wear with the application of negative pressure. The patient-reported outcomes were favorable.

The MPD can safely and comfortably be worn overnight. The decrease in IOP of >20% in addition to current therapy is both clinically and statistically significant. The MPD shows promise as a potential new treatment option for nocturnal IOP control.

Diabetic retinopathy (DR) is the emerging cause of blindness in developing countries. This study aimed to assess the accuracy of grading retinal findings of patients with diabetes using fundus photographs by allied medical personnel (AMP) when compared to an ophthalmologist.

Six AMPs were enrolled for grading fundus photographs of patients with diabetes after three and six months of training twice at two weeks interval. The total number of fundus photographs graded were 1,344. Grading by a retina specialist was used as the gold standard. Intra-rater and inter-rater agreement was assessed using the kappa coefficient (k).

The intra-rater agreement of half of the AMPs in both three months and six months was almost perfect for grading of any retinal abnormalities, and substantial for retinal hemorrhages. In three months, the overall inter-rater agreement at the second rating was moderate for any retinal abnormalities (k=0.60) and retinal hemorrhage (k=0.48) and was fair for macular exudates (k=0.35). The ovr retinal hemorrhages and macular exudates. The agreement results were almost similar at three months and six months. AMPs could be utilized in screening of DR and other retinal pathologies for timely referral to reduce the blindness in low-resource settings.Objective This article reports on 3-year clinical outcomes of the Sonography Guided Transcervical Ablation of Uterine Fibroids (SONATA) pivotal trial of transcervical fibroid ablation (TFA) in women with symptomatic uterine myomata. Materials and Methods The SONATA, prospective, controlled, multicenter interventional trial enrolled 147 premenopausal women with symptomatic uterine fibroids who underwent uterus-preserving, sonography-guided TFA with the Sonata® System (Gynesonics, Inc., Redwood City, CA, USA). Clinical outcomes were assessed over 3 years and included surgical reinterventions, Symptom Severity Score (SSS), and Health-Related Quality of Life (HRQoL) subscales of the Uterine Fibroid Symptom and Quality-of-Life Questionnaire, EuroQol 5-Dimension (EQ-5D) questionnaire, Overall Treatment Effect, treatment satisfaction, physical activity, work impairment, pregnancy outcomes, and adverse events. Results The 3-year rates of surgical reintervention for heavy menstrual bleeding calculated by the binomial and Kaplan-Meier methods were 9.2% and 8.2%, respectively. Compared to baseline, mean SSS decreased from 55 ± 19 to 22 ± 21, HRQoL increased from 40 ± 21 to 83 ± 23, and EQ-5D increased from 0.72 ± 0.21 to 0.88 ± 0.16 (all p  less then  0.001). Treatment benefit on the SSS, HRQoL, and EQ-5Q exceeded the minimal clinically important difference at every follow-up visit over 3 years. At 3 years, 94% of the subjects reported treatment satisfaction, 88% reported reduced fibroid symptoms, work absenteeism due to fibroid symptoms decreased from 2.9% to 1.4%, and impairment due to fibroids decreased from 51% to 12% for work, and 58% to 14% for physical activity (all p  less then  0.001). No late complications occurred. Conclusions Women treated with sonography-guided TFA in the SONATA pivotal trial experienced significant and durable reduction of fibroid-related symptoms, with low surgical reintervention rates over 3 years of follow-up.
Despite the availability of antidiabetic drugs, they are not free from associated adverse side effects. This study aimed to evaluate the hypoglycemic and hypolipidemic effects of oral administration of seeds from two medicinal plants (1) Milk thistle and (2) fenugreek.

Plant seeds were washed in distilled water and ground with a coffee grinder. Alloxan was used to induce diabetes in 20 male albino rats. Diabetic rats were randomly divided into two groups (1) Group 1 (n=10), diabetic rats fed with 0.5 g/kg milk thistle and 2 g/kg fenugreek seeds per day and (2) Group 2 (n=10), diabetic rats fed standard rodent food for 4 weeks.

Oral administration of milk thistle and fenugreek seeds for 2 weeks resulted in significant improvement in body weight, blood glucose, glycosylated hemoglobin (HbA1c), cholesterol, and triglyceride levels in alloxan-induced diabetic rats. After 4 weeks, this ameliorative effect was significantly elevated with respect to blood glucose (155.00±9.70 mg/dL vs. 427.50±5.70 mg/dL; p<0.
