About this study

Official title: Mid-term Clinical Assessment and Correlation Between Metamorphopsia, Visual Acuity and Foveal Thickness in Idiopathic Epiretinal Membrane and Cataract Surgery

This study evaluates the safety and efficacy simultaneous, trans-conjunctival, 25-Gauge vitrectomy and phacoemulsification with intraocular lens implant in patients with metamorphopsia and visual impairment due to idiopathic epiretinal membrane and cataract. All 30 patients recruited underwent complete ocular examination, visual acuity measurement with ETDRS, metamorphopsia assessment with M-Charts and Metamorphometry® and foveal thickness evaluation by sd-OCT preoperatively, at 30, 90, 180 days postoperatively.

Being tested
Phacoemulsification, intraocular lens implant, vitrectomy.
Keywords
Metamorphopsia, Epiretinal membrane, Vitrectomy
Medical subject headings
Epiretinal Membrane, Vision Disorders

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Metamorphopsia

    Change in spatial degree of distortion perception

    Measured: Change in metamorphopsia from baseline at 180 days.

  2. Visual Acuity

    Change in LogMAR visual acuity

    Measured: Change in visual acuity from baseline at 180 days

  3. Area of central scotoma

    Change in area, in square pixel, of central scotoma

    Measured: Change in area of central scotoma from baseline at 180 days

  4. Central fovea thickness

    Change in fovea thickness in µm at the Sd OCT

    Measured: Change in fovea thickness from baseline at 180 days

Questions about this trial

What is this clinical trial studying?

An observational study of Epiretinal Membrane and Cataract Senile, run by Clinica Oculistica dell'Università di Torino.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Metamorphopsia (time frame: Change in metamorphopsia from baseline at 180 days.). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Feb 2017.
