Lacquer cracks observed in peripheral fundus of eyes with high myopia

ABSTRACT

We report a case with lacquer cracks observed in the peripheral fundus. A 37-year-old patient with bilateral high myopia who visited our clinic was examined by fluorescein angiography (FA) and fundus autofluorescence (FAF) to determine whether there were myopic fundus lesions. FA showed many arch-shaped, hyperfluorescent linear lesions running circumferentially in the peripheral fundus. FAF showed hypo-autofluorescence at the corresponding sites. These characteristics were very similar to the lacquer cracks present in the posterior fundus in highly myopic eyes. Although lacquer cracks in the peripheral fundus are rare, they should be considered in the differential diagnosis of peripheral linear lesions showing hyperfluorescence in FA.

Mentions: A 37-year-old man visited the High Myopia Clinic of the Tokyo Medical and Dental University hospital with a complaint of decreased vision in both eyes. He had no prior medical or ophthalmological history and was not taking any medications. His visual acuity was 20/20 in both eyes, and the refractive error was −14.5 D OD (right eye) and −14.0 D OS (left eye). The axial length was 30.8 mm OD and 30.6 mm OS. Dilated fundus examination showed that the optic disk cups were enlarged in both eyes, but there were no abnormalities in the peripheral region ophthalmoscopically (Figure 1). He was suspected to have glaucoma in both eyes, and the Goldmann perimetry was performed. A slight reduction in the sensitivity in the nasal visual field of the left eye was found. FA and FAF were performed to determine whether the fundus was normal. FA showed multiple arch-shaped, hyperfluorescent linear lesions running circumferentially in the peripheral fundus of both eyes. Some of these lesions were observed to run parallel to each other (Figure 2). FAF showed hypoautofluorescence at the corresponding sites (Figure 3). From these findings, we diagnosed these lesions as lacquer cracks in the peripheral fundus. 3D MRI showed that the shapes of both eyes were normal without posterior staphylomas. However, the entire posterior region of the globe was enlarged in both eyes (Figure 4).
