Research summary
Introduction: Image distortion is a common complaint after surgery for retinal detachment (RD). Displacement of the retina after RD repair surgery can serve as anatomy basis of vision distortion. Previous studies demonstrated that Fundus auto-fluorescence imaging (FAF) is able to detect the retinal displacement after RD repair through lines of Retinal Vessel Printing (RVP) which correspond to the area where the retinal blood vessels were located before the RD.
Objective: To compare retinal displacement and visual distortion after primary retinal detachment repair following two different RD treatment options, both of which are in routine use at Newcastle Eye Centre presently: pneumatic retinopexy (PnR) vs pars plana vitrectomy (PPV).
Hypothesis: The primary study hypothesis is that PnR will cause less retinal displacement and less visual distortion/stretch at 12 months post repair for patients with primary RD
Methods: A prospective observational (data-collection) cohort study comparing two surgical treatments (PnR versus PPV) for patients with primary RD. All adult patients (>18 years) presenting to Newcastle Eye Centre with primary macula off rhegmatogenous RD (i.e. due to a retinal tear) shall undergo RD repair surgery using the routine surgical approach, as advised by the the treating vitreoretinal surgeon. Patients will undergo retinal examination, retinal imaging (including FAF), an assessment of visual acuity, and self-reported distortion/stretching of vision at 3 and 12 months post intervention.
