4M.D. Professor, Ulucanlar Eye Training and Research Hospital Eye Clinic, Ankara/TURKEY Posterior microphthalmos (PM) is a relatively rare type of microphthalmos in which the posterior segment is predominantly affected with normal anterior segment findings. The main findings are high hypermetropia and elevated papillomacular folds. This paper consists of clinical and imaging findings of 3 PM cases. All cases had high hypermetropia (+17.00, +19.00, +17.00 dioptry) in cycloplegic refraction. The dilated fundus examination revealed elevated papillomacular folds in all the cases and crowded disk in only 2 of the 3 cases. In the B-scan ultrasound evaluation sclerochoroidal thickening, decreased total axial length (14.6-15.0 mm), and marked foreshortening of the posterior segment were noted. Fundus fluorescein angiography was performed in 2 patients and in those in which angiography was performed the foveal avascular zone seemed to be significantly reduced. Optic coherence tomography demonstrated the elevated papillomacular folds seen on dilated fundus examinations. The diagnosis of PM should be considered in patients with high axial hypermetropia, elevated papillomacular retinal folds, and normal anterior segment examination. Patients should be followed up properly for refractive amblyopia and for the complications that may emerge. Keywords : Posterior microphthalmos, hypermetropia, papillomacular fold
