To study the morphological features of the macula of patients with retinitis pigmentosa and visual acuities of 20/200 or less as examined by optical coherence tomography.
In an observational case series study, 42 eyes (21 patients) with retinitis pigmentosa and visual acuities of 20/200 or less were evaluated by optical coherence tomography.
Thirty-four (81%) eyes had atrophic retina (group 1) and 8 (19%) eyes had cystoid macular edema (group 2). The mean visual acuity was 20/1000 in group 1 and 20/300 in group 2. Epiretinal membrane was identified in 27 (64.3%) eyes.
Optical coherence tomography is a more sensitive method in detecting macular pathology and can help in selecting cases where treatment may be applied.
通过光学相干断层扫描研究视力为20/200或更低的视网膜色素变性患者黄斑的形态学特征。
在一项观察性病例系列研究中，对42只眼（21例患者）视力为20/200或更低的视网膜色素变性患者进行了光学相干断层扫描评估。
34只眼（81%）有视网膜萎缩（第1组），8只眼（19%）有黄斑囊样水肿（第2组）。第1组平均视力为20/1000，第2组为20/300。27只眼（64.3%）发现有视网膜前膜。
光学相干断层扫描是检测黄斑病变更敏感的方法，有助于选择可能适用治疗的病例。
