ABSTRACT
CLINICAL RELEVANCE: Vitreomacular traction(VMT) is a clinical syndrome that can cause decreased vision and may affect the treatment response in cases of age-related macular degeneration(AMD). Factors affecting the course of VMT in AMD cases will guide the clinician in terms of patient management. BACKGROUND: The aim of this study was to determine the prevalence of VMT in patients with AMD, to evaluate the natural course of VMT, and to investigate factors associated with the prognosis of VMT in eyes with AMD. METHODS: This retrospective case series was conducted with 55 eyes of 46 patients who were diagnosed as having AMD accompanying with VMT. Demographic data, complete ophthalmologic examination findings, type of AMD, receiving an intravitreal injection(IVI), number of IVIs, and the presence of complete spontaneous release were obtained from the medical records of the patients. The horizontal length of VMT(HLVMT), central macular thickness(CMT), the horizontal length of choroidal neovascularization(HLCNV) were evaluated from spectral-domain optical coherence tomography(SD-OCT) images. RESULTS: Spontaneous release was observed in 7(28%) eyes of the exudative AMD group and 10(33.3%) eyes of the nonexudative AMD group. On the last visit, the HLVMT was increased in 22(40%) of the eyes and a decrease in HLVMT was observed in 8(14.5%) of the eyes. In the remaining 12(21.8%) eyes had unchanged HLVMT. In all eyes with CNV, the area of VMT corresponded in 100% with localization of the CNV complex. No significant difference was found between the eyes with spontaneous release and persistent traction in terms of the type of AMD, IVI, HLVMT, age, gender, and crystalline lens status. CONCLUSION: In this study, VMT was observed at higher rates in eyes with exudative AMD compared to the eyes with nonexudative AMD. However, spontaneous release rates were found close to those with idiopathic VMT independently of the type of AMD, HLVMT, and IVI.
