We report a case of 19-year-old man with gradual diminution of vision in both eyes since childhood. His best-corrected visual acuity was 20/160, N16 in the right eye and 20/200, N16 in the left eye. Slit-lamp biomicroscopic examination revealed normal cornea, anterior segment, intraocular pressure and lens. Fundus of both eyes showed crowded optic disc with pigmentary changes. Ancillary tests were performed to aid in the diagnosis. A-scan ultrasound revealed short axial lengths with normal corneal diameter, anterior chamber depth and lens thickness. Optical coherence tomography of both eyes showed inner retinal layer folds. Electroretinogram of both eyes showed extinguished photopic as well as scoptopic responses. A diagnosis of posterior microphthalmos with pigmentary retinopathy was made. The patient was counselled regarding nature of the disease and the condition was managed with low vision aids.
我们报告了一例 19 岁男性,自幼双眼视力逐渐下降。最佳矫正视力右眼为 20/160,左眼为 20/200,N16。裂隙灯显微镜检查显示正常的角膜、前段、眼压和晶状体。双眼眼底显示视盘拥挤伴色素改变。辅助检查有助于诊断。A 型超声显示短眼轴,正常角膜直径、前房深度和晶状体厚度。双眼光学相干断层扫描显示内层视网膜褶皱。双眼视网膜电图显示明适应和暗适应反应熄灭。诊断为后部小眼球伴色素性视网膜炎。向患者告知了疾病的性质,并通过低视力辅助器具进行了治疗。
