Abstract
Purpose::
To estimate the prevalence and effect on visual acuity of macular pseudoholes and lamellar macular holes in patients with retinitis pigmentosa.
Methods::
We studied 316 patients with typical forms of retinitis pigmentosa, evaluating their macular appearance by ophthalmoscopy, fundus photography and optical coherence tomography (OCT 3).
Results::
Eleven patients (3%) with an average age of 41 years were found to have macular pseudoholes or lamellar holes in one or both eyes. Their visual acuities ranged from 20/20 to 20/60 with the average reduction being 2 lines. The ocular media were clear. No patient in this series was found to have a full thickness macular hole.
Conclusions::
Macular pseudoholes and lamellar holes occur at a higher frequency in retinitis pigmentosa than in the general population. In retinitis pigmentosa they have a slight to moderate effect on visual acuity.
