To assess the dynamics of retinal morphologic and functional changes in patients with exudative form of age-related macular degeneration after intravitreal injection of ranibizumab and statins` therapy.
Department of Ophthalmology of Bukovinian State Medical University, Eye microsurgery clinic “Vash Zir”, Chernivtsi, Ukraine
The study comprised 22 patients (24 eyes) with a mean age of 62,4 years with exudative form of age-related macular degeneration (AMD) after 3 consecutive monthly intravitreal injections of ranibizumab (Lucentis®). The drug was injected through the pars plana 3,5 mm posterior to the limbus using a 30-gauge needle. 12 patients (13 eyes) of main group received statins` therapy in dose 10 mg per day during 6 months. The major efficacy criteria were the corrected visual acuity (VA) changes from baseline, morphological changes in macula (central macular thickness, CMT) according to optical coherence tomography (OCT) (RTVue-100, Optovue, USA) data (3D-macula Protocol, Macula Thickness Map Program) and the number of reinjection required over the 12-month follow-up. Statistical significance was defined as р<0,05. Retreatment was recommended if new or persistent fluid was demonstrated on OCT; an increase in CMT from previous measurement due to fluid on OCT; VA deterioration related to fluid on OCT.
At baseline, the mean VA was 0,16±0,14; a mean CMT at baseline was 379,34±103,61 μm. At 6 months after the first ranibizumab injection the best corrected VA was remarkably higher (0,48±0,20) as compared with its baseline value (р<0,05) in all patients. At 12 months VA in patients of main group was 0,41±0,19, in patients of control group - 0,32±0,16 without statistically significant difference. CMT values at 6 months were 314,46±62,34 μm in main group and 322,44±64,67 μm in control group; at 12 months - 284,32±64,67 μm and 318,30±67,56 μm, respectively (р<0,05). During 12-month follow-up 23,08% eyes of main group and 45,46% eyes of control group needed retreatment.
It was established that statins` administration in complex treatment of exudative form of AMD helps to preserve the effect of anti-VEGF therapy and reduce the number of reinjection that allows to recommend them for use in this pathology.
