Our aim in reporting this case of optic nerve head drusen detected by B-mode USG and showing autofluorescence in red free fundus photograph is to evaluate retinal nerve fiber layer defect with OCT and to evaluate the visual field defect with the use of automated perimetry and to show that these defects do not always correlate.

📌 3 Key Takeaways

🎯
Objective & Hypothesis:Optic nerve head drusen are acellular calcified concretions located prelaminarly.
📊
Key Findings & Data:Compression of ganglion cells by calcified hyaline structures results in alteration in axoplas- mic flow and cell death and so visual field and retinal nerve fiber layer defects are seen in optic nerve head drusen.
💡
Conclusion & Impact:Our aim in reporting this case of optic nerve head drusen detected by B-mode USG and showing autofluorescence in red free fundus photograph is to evaluate retinal nerve fiber layer defect with OCT and to evaluate the visual field defect with the use of automated perimetry and to show that these defects do not always correlate.

Abstract

Optic nerve head drusen are acellular calcified concretions located prelaminarly. Compression of ganglion cells by calcified hyaline structures results in alteration in axoplas- mic flow and cell death and so visual field and retinal nerve fiber layer defects are seen in optic nerve head drusen. Our aim in reporting this case of optic nerve head drusen detected by B-mode USG and showing autofluorescence in red free fundus photograph is to evaluate retinal nerve fiber layer defect with OCT and to evaluate the visual field defect with the use of automated perimetry and to show that these defects do not always correlate.

Özet

Optik sinir başı druseni prelaminar alanda yerleşen aselü- ler kalsifiye yapılardır. Optik sinir başı druseninde kalsifiye hyalin yapıların ganglion hücrelerine basısı sonucu akzop- lazmik akımın bozulması ve hücre ölümüne bağlı görme alanı ve retina sinir lifi defektleri görülmektedir. B-mod ultrasonografi (USG) ile saptanan ve kırmızıdan yoksun çekilen fundus fotoğrafında otofloresans görülen olguyu sunmadaki amacımız optik sinir başı druseninde optik koherens tomografi (OCT) ile retina sinir lifi defekti ve otomatik perimetri ile görme alanı defektini değerlen- dirmek; bu defektlerin her zaman birbiri ile uyumlu olma- dığını göstermektir.
