Abstract

Best VitellifomMakulaDistrofisi (BVMD), nadir görülen kalıtsal bir makuladistrofisidir. BVMD'nin klinik değerlendirmesinde çeşitli evreleme sistemleri uygulanmaktadır. Bu olgu sunumunda 9 yaşında bir erkek çocukta sikatrisyel evrenin varlığının gösterilmesi amaçlanmaktadır. 9 yaşında erkek çocuk, sağ gözünde görme keskinliği azalması şikayetiyle Eskişehir Yunus Emre Devlet Hastanesi Göz Hastalıkları kliniğine başvurdu. Hastanın soy geçmişi sorgulandığında, ailedeki diğer bireylerin de görme kaybı nedeniyle başka bir merkezde takip edildiği öğrenildi. BMVD tanısı elektrofizyolojik testler ve ek klinik çalışmalar kullanılarak doğrulandı. Optik koherenstomografide her iki gözde subretinal sıvı ile uyumlu hiporeflektif lezyon izlendi. Ayrıca sağ gözde tümsek şeklinde subretinalhiporeflektif lezyon tespit edildi. BVMD'li olgularında hastalığın erken evrelerinde görme keskinliği genellikle stabildir. Ancak görme bozukluğunun varlığı genellikle koroidalneovaskülermembran gelişiminin bir işareti olarak düşünülür. Nadir de olsa hastalığın ileri evrelerinde görülen sikatrisyel evre küçük çocuklarda da görülebilmektedir. Özellikle çocuklarda ambliyopi riski nedeniyle koroidalneovaskülermembranınsikatrisyel evreden ayırt edilmesi ve doğru tedavi planlaması yapılması gerekmektedir.

Demonstrationof CicatricialStagewith Optical CoherenceTomography in A Child with Best VitelliformMacularDystrophy

Abstract

Best vitelliform macular dystrophy (BVMD) is a rare hereditary macular dystrophy. Various staging systems are performed in the clinical evaluation of BVMD. In this case report, it is aimed to demonstrate the presence of cicatricial stage in a 9-year-old boy. A 9-year-old boy was applied to our Eskisehir YunusEmre State Hospital OphthalmologyClinic with decreased visual acuity in his right eye. When the family history of the patient was questioned, it was learned that the other family members were also followed in another center due to loss of vision. BMVD diagnosis was confirmed by using electrophysiological tests and additional clinical studies. In optical coherence tomography, a hyporeflective lesion consistent with subretinal fluid was observed for both eyes. Additionally, a hump-shaped subretinalhyporeflective lesion was found in the right eye. Visual acuity is generally stable in the early stages of the disease for patients with BVMD, but the presence of a visual impairment is usually thought as a sign of the development of a choroidal neovascular membrane. Although rare, however, cicatricial stage, which is observed in the advanced stages of the disease, can be seen in small children. Distinguishing choroidal neovascular membrane from the cicatricial stage is necessary especially in children due to the risk of amblyopia and to make an accurate treatment planning.
