Filter by:Post-operative infectious endophthalmitis is devastating condition that causes a diffuse intraocular inflammation and may lead to blindness. Acute post-operative endophthalmitis usually presented within 6 weeks of intraocular procedure and diagnosis is confirmed by clinical examination and by the aid of B-scan ultrasonography.
This study was an experimental, single-blinded, randomized controlled trial that aimed to compare recovery time between TCI propofol and sevoflurane. After ethical approval from Research Ethical Committee Faculty of Medicine, Universitas Indonesia (879/UN2.F1/ETIK/2017) and informed consent, patients aged 18-65 years old, body mass index 18 - 30 kg/m2, American Society of Anesthesiologists (ASA) status I-II who were scheduled for vitrectomy surgery under general anesthesia, at Kirana's Eye Operating Theatre Cipto Mangunkusumo National Referral Hospital from September until December 2017, were recruited in this study. All subjects would be recruited with a consecutive sampling method and randomly assigned into two groups, the TCI propofol group and sevoflurane group. Block random allocation was done for all subjects by using the random allocator program Winpepi.
This is a single-center, prospective randomized controlled trial evaluating the safety and efficacy of YAG vitreolysis versus sham for symptomatic Weiss ring due to posterior vitreous detachment.
A Phase 2, Randomized, Double-masked, Placebo-controlled Multicenter Clinical Trial Designed to Evaluate the Safety and Efficacy of Luminate in Inducing PVD in Subjects with Non-Proliferative Diabetic Retinopathy.
Vitreous floaters are tiny, cloudy, clumps of cells that appear in the otherwise clear fluid (vitreous) that fills the back 3/4 of the eye. Floaters are commonly caused by eye conditions such as posterior vitreous detachment (PVD), vitreous syneresis and asteroid hyalosis. While these symptoms are considered physiological in nature, they can be of considerable inconvenience to many patients which affect essential activities. The investigators wish to assess the safety and efficacy of floater treatment in patients with highly symptomatic floaters using an FDA approved nanosecond infrared yttrium aluminum garnet (YAG) lasers.
The objective of this research is to improve the care of ocular disease and disorders, in particular the changes in the eye associated with diabetes, by providing clinicians with dramatically improved ultrasonic images of the entire eye. The research combines advanced high-frequency, high-resolution ultrasonic annular arrays transducers with new processing techniques designed to overcome several limits that have been reached with conventional high frequency ultrasound systems. The investigators propose that diagnosis of eye diseases using annular arrays can be more effective than the conventional ultrasound images by at least 50%; i.e., that for every 2 posterior vitreous detachments detected conventionally, 3 will be detected with the annular arrays.
This is a study of subjects with retinal vein occlusion (RVO) specifically looking at the difference in outcomes between patients with posterior vitreous detachment (PVD) and those without PVD. Posterior vitreous detachment is a condition where the gel-like substance that occupies the space between the retina and the lens of the eye liquefies and separates from the retina. 20 subjects from Barnes Retina Institute will be enrolled in this study. Based on a pre-treatment ultrasound (a test utilizing high-frequency sound waves to look at the inside of the eye), high resolution OCT (a noninvasive procedure called optical coherence tomography to check the thickness of your retina) and clinical exam, subjects will be assigned to one of 2 groups at baseline: Group 1 will be those with PVD and Group 2 will be those without PVD. Then subjects will receive monthly intravitreal (inside the eye) injections of Ranibizumab.

The purpose of this study is to compare the newly released Spectral OCT/SLO (OTI, Toronto, Canada) with the Zeiss Stratus OCT (Carl-Zeiss Meditec, Dublin, CA) with regards to the quality of the images obtained as well as the ease of use.
The purpose of this study is to assess the efficacy of intravitreous injections of Vitrase to induce posterior vitreous detachment(PVD) in subjects with moderate to severe non-proliferative diabetic retinopathy.
