Assessment Of Diabetic Maculopathy Changes After Phacoemulsification by Using Optical Coherence Tomography

Maculopathy
Start date: March 2023
Phase:
Study type: Observational [Patient Registry]

Investigators aimed to assess the macular changes with OCT after uncomplicated phacoemulsification surgery in diabetic patients with non proliferative diabetic retinopathy (NPDR) at the time of surgery and the effect of perioperative and postoperative topical NSAIDS on macular changes .

NCT ID: NCT04023123 Completed - Maculopathy Clinical Trials

Anterior Corneal Striae in Hypotony

Start date: September 17, 2019
Phase:
Study type: Observational

The goal of this is to evaluate the biomechanical properties of hypotonous eyes with vertical anterior corneal striae and/or hypotony maculopathy compared to hypotonous eyes without striae.

NCT ID: NCT03902925 Completed - Clinical trials for Diabetic Retinopathy

Pain During Pars Plana Vitrectomy With Sub-tenon Anesthesia

Start date: January 1, 2019
Phase: Phase 1/Phase 2
Study type: Interventional

Vitreoretinal surgery has evolved to less invasive procedures, and it is used to treat a wide range of diseases. So anesthesia for vitreoretinal procedures has evolved, promoting adequate analgesia while reducing risks to the patient. In the present study two types of procedures for anesthesia during vitreoretinal surgery are evaluated regarding the pain referred by the patient during the whole procedure: peribulbar anesthesia versus sub-tenon injection plus topical jelly anesthesia. Through the comparative analysis of the pain scale of the two groups it is expected that the two modalities present the same anesthetic efficacy, showing that the methods used may be equivalent.

NCT ID: NCT03476291 Active, not recruiting - Maculopathy Clinical Trials

Research of Automated Maculopathy Screening Based on AI Techniques Using OCT Images

Start date: June 30, 2017
Phase:
Study type: Observational

The investigators expect to develop an algorithm that can interpret OCT images and automated determine whether the macula is normal or not by using OCT image-based deep learning techniques. And investigators wish to develop software applications that will help better screen and diagnose macular diseases in resource-limited areas.

NCT ID: NCT03185936 Completed - Maculopathy Clinical Trials

Surgical Management of Optic Disc Pit Maculaopathy

Start date: March 1, 2011
Phase: N/A
Study type: Interventional

To evaluate the anatomical and functional results of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) peeling, endolaser photocoagulation and gas tamponade in management of optic disc pit (ODP) maculopathy.

NCT ID: NCT03011541 Recruiting - Glaucoma Clinical Trials

Stem Cell Ophthalmology Treatment Study II

SCOTS2
Start date: January 2016
Phase: N/A
Study type: Interventional

This study will evaluate the use of autologous bone marrow derived stem cells (BMSC) for the treatment of retinal and optic nerve damage or disease.

NCT ID: NCT02805686 Completed - Maculopathy Clinical Trials

" En Face " OCT's Contribution in the Detection of Macular Retinal Toxicity Signs Linked to the Chronic Treatment of Synthetic Antimalarials

OCTAPS
Start date: June 2014
Phase: N/A
Study type: Interventional

The maculopathy induced by the retinal toxicity of the synthetic antimalarials must be detected at the infra-clinical state, when it can still be reversible. Identifying early retinal anatomical changes has always represented (a challenge for medical interns, dermatologists, rheumatologists, and ophthalmologists). Currently, the gold-standard for its screening and its diagnostic is the multifocal electroretinogram (mfERG), however it is a long and tedious exam, offered by only few medical centers. It is recommended to find a simple non-invasive alternative, on a commonly used equipment. The study of the ellipsoid (junction line between, the external and internal photoreceptor segments) using optical coherence tomography (OCT-SD) "en face" enables us, to obtain a panoramic viewing of the state of the photoreceptor layer, and to detect any modification, even subtle, within this layer. The OCT-SD "en face" can be easily done by any ophthalmologist who owns one. The proportion of "en face" OCT-SD showing suggestive retinal damage and patients who present retinal damage in relation with synthetic antimalarial treatments and diagnosed by mfERG is considered in this study.

Vision Measured by the Vimetrics CVA Compared With Chart Testing Under Similar Luminance and Contrast Conditions

Start date: January 2008
Phase: N/A
Study type: Observational

Purpose of The Study: The purpose of this study is the following: A)To gather age-related normative visual acuity data for the Vimetrics Central Vision Analyzer (CVA, Vimetrics, LLC, Media, Pa) B)To gather visual acuity data for patients with known ocular problems, including cataract and maculopathy. C)To correlate and compare the CVA visual acuity findings with the acuity measured with standard LogMAR acuity charts viewed under similar conditions of contrast and lighting
