Diabetic Retinopathy

This was a multicentre, randomised, double-blind controlled study that compared the efficacy and safety of V. vinifera extract, calcium dobesilate (CD), and placebo in subjects with DME. Patients made 6 clinic visits, namely the screening visit; baseline visit (T0); and follow-up visits at 3 (T3), 6 (T6), 9 (T9), and 12 (T12) months.

First in Human Study to Evaluate the Safety and Tolerability of GEM103 in Geographic Atrophy Secondary...

Dry Age-related Macular DegenerationGeographic Atrophy3 more

The study is designed to identify the maximum tolerated dose (MTD) for intravitreal (IVT) administration of GEM103 in subjects with geographic atrophy (GA) secondary to dry AMD. Safety and tolerability of a single dose of GEM103 will be assessed based on the occurrence of dose-limiting toxicities (DLTs). Each subject will be followed for safety, pharmacokinetic (PK), clinical, and biomarker evaluations. Three escalating dose cohorts are planned.

ETDRS PRP With IVR Versus Retinal Photocoagulation Targeted to Ischemic Retina With IVR for the...

Diabetic Retinopathy

Purpose: To compare panretinal photocoagulation (PRP) as described in ETDRS Study combined with intravitreal injection of ranibizumab (IVR) (ETDRS-PRP group) and retinal photocoagulation targeted to ischemic retina combined with IVR (ISQ-RP group) in patients with proliferative diabetic retinopathy (PDR). Design: Randomized prospective clinical trial. Methods: Patients with PDR were assigned to receive either PRP plus IVR (20 eyes) or retinal photocoagulation targeted to ischemic areas plus IVR (20 eyes). ETDRS best-corrected visual acuity (BCVA), central subfield macular thickness (CSFT) measured by optical coherence tomography (OCT) were performed at baseline and every 4 weeks through week 48. Area of fluorescein leakage from active new vessels (FLA) was measured every 12 weeks. Full-field electroretinography (ERG) was recorded at baseline and after 3 months.

Acupuncture for Preterm Infants Requiring Eye-exam

Retinopathy of PrematurityPain2 more

The purpose is to investigate whether non-invasive acupuncture - NIA (i.e. acupuncture without needles) will help reduce pain for babies in the Neonatal Intensive Care Unit (NICU) during their routine weekly eye-exam for Retinopathy of prematurity. Retinopathy of prematurity (ROP) is an eye disease most commonly affecting premature babies born weighing less than 1250 grams. Retinopathy of prematurity occurs because these premature babies require oxygen because of their immature lungs. The oxygen then stimulates the growth of blood vessels in the retina, causing the retina to be detached from the eye, which causes vision impairment. To examine if the vessels grow at the back of the eye, an eye-doctor visits bi-weekly once the baby is 32 weeks corrected age to assess if the blood vessels change. If there is a lot of growth, the eye-doctor would use a laser to treat the eye to prevent further growth. During the bi-weekly eye-exam, the premature infant receives sucrose (a type of sugar) for pain management. The investigator will assess pain a premature babies experience during this exam and found that there are extremely high scores of pain despite sucrose and the investigator believe this pain and stress caused by these procedures could be reduced by adding: Magnetic Acupuncture Also, untreated pain causes stress (lower oxygen levels, higher heart rates), discomfort and poorer long term outcomes. Finding the best treatment and prevention for the pain caused by procedures in the NICU is therefore extremely important for any baby.

The Effect of Eyemasks on Neonatal Stress Following Dilated Retinal Examination

Retinopathy of PrematurityPain2 more

Although screening exams for retinopathy of prematurity (ROP) prevent blindness they are physiologically stressful for infants. The investigators postulate that photosensitivity during mydriasis contributes to post-examination stress and that reducing light stimulation with a phototherapy mask can make infants more comfortable. The objective of this study is to determine the effect of a phototherapy mask worn during mydriasis on infant stress in the 12 hour period following ROP screening.

Pattern Laser Versus Conventional Laser in Diabetic Retinopathy

Diabetic Retinopathy

Purpose: To evaluate the clinical efficiency, safety and painfulness of retinal laser photocoagulation employing a pattern scanning laser system Pascal given in a single-session versus conventional laser multiple-session treatment of the same patient with diabetic retinopathy. Methods: The cohort included 60 eyes in 30 patients treated at the Ophthalmology Clinic, Faculty Hospital Ostrava, from 2008 to 2013. Panretinal laser coagulation was performed on one eye using the multispot panretinal photocoagulation given in a single-session system Pascal (SSP) (OptiMedica, Santa Clara, California). On the other eye laser treatment was carried out by the classic conventional multiple-session method (MSM).

Combined Antioxidant Therapy on Oxidative Stress, Mitochondrial Dysfunction Markers in Diabetic...

Diabetic Retinopathy

The present study aims to support previous research on antioxidant therapy effects in diabetic retinopathy outcome. The investigators intend to assess 180 patients with diabetic retinopathy in different stages (moderate, severe and proliferative), whom either will be assigned to placebo group or combined antioxidant therapy. Each group will receive the intervention for 12 months. Such intervention consists in taking one tablet (placebo or antioxidant therapy) orally, a day. At baseline, blood and urine samples will be collected in order to assess metabolic and oxidative stress status, mitochondrial function or dysfunction, liver and kidney function. In addition, fluorescein angiography will be done for the categorization of diabetic retinopathy. After six months and at the end of the intervention, blood and urine measurements as well as angiographies will be done for comparing the outcomes between both groups and correlate oxidative stress status, mitochondrial dysfunction with grade of retinopathy.

Expansion of Integrated AI Solution for Diabetic Retinopathy Screening in Thailand

Diabetic Retinopathy

Efficiency and effectiveness of real-world diabetic retinopathy screening by artificial intelligent (AI) are limited. Investigators will implement AI for diabetic retinopathy screening in 13 health districts in Thailand and investigate the efficiency, effectiveness as well as patients and health care personnel's satisfaction by an implementation research.

Observation of the Efficacy of Different Vitrectomy Systems to Treat Proliferative Diabetic Retinopathy...

Proliferative Diabetic RetinopathyVitrectomy

In recent years, vitrectomy has moved toward a minimally invasive vitrectomy surgery (MIV) system, which could effectively reduce the occurrence of operation complications, while reducing the time of post-operation recovery. With an improved design of bevel tip and a high cutting rate capacity of 10000cpm, Advanced ULTRAVIT® probes potentially provide an strong technical support for the application of MIV. The new probe facilitates great control during delicate surgical maneuvers, such as separating the hyaloid from the retinal surface, dissecting fibrovascular tissue off the surface of retina. However, there was no sufficient clinical evidence to support the benefits of Advanced ULTRAVIT ® probes in the complicated vitreoretinal surgery, such as proliferative diabetic retinopathy. More importantly, there is an urgent need of clinical evidence to support 10000cpm launch and conversion which is major objective of 2021 VR growth strategies.
