HIGH-RESOLUTION OPTICAL COHERENCE TOMOGRAPHY FINDINGS IN OPTIC PIT MACULOPATHY

Purpose: The purpose of this study was to characterize retinal manifestations of optic pit maculopathy using high-resolution optical coherence tomography. Methods: Consecutive patients with optic pit maculopathy, diagnosed by their typical appearance by ophthalmoscopy, were imaged by color fundus photography and optical coherence tomography. The location and characteristics of any fluid within and under the retina were determined. Results: The mean age of the 16 patients (7 women) was 35.9 years (standard deviation: 18.5 years). The visual acuity ranged from 20/20 to 20/1000 (median, 20/200). Retinal detachment was found in 11 eyes (69%), intraretinal fluid in the outer nuclear layer in 15 eyes (94%), in the inner nuclear layer in 13 eyes (81%), in the ganglion cell layer in 7 eyes (44%), and in the subinternal limiting membrane space in 2 eyes (13%). An outer layer hole was identified in only 3 of 11 eyes (27%) with retinal detachment. Conclusion: Fluid from the optic pit can go directly to the subinternal limiting membrane space, ganglion cell layer, inner nuclear layer, outer nuclear layer, or the subretinal space, although the outer nuclear layer is most commonly affected. An outer layer hole appears not to be common in optic pit maculopathy. RETINA 30:1104-1112, 2010
