Optical coherence tomography findings in patients with retinitis pigmentosa and low visual acuity

Ophthalmic Surg Lasers Imaging. Jan-Feb 2010;41(1):35-9. doi: 10.3928/15428877-20091230-07.


Background and objective: 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.

Patients and methods: 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.

Results: 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.

Conclusion: Optical coherence tomography is a more sensitive method in detecting macular pathology and can help in selecting cases where treatment may be applied.
