Abstract Details

Purpose:

To describe the spectral-domain optical coherence tomography (SD-OCT) features of peripheral round retinal holes, with or without associated retinal detachment.

Setting:

Moorfields Eye Hospital, UK

Methods:

Retrospective image-based and case notes review of patients with peripheral round retinal holes with or without associated retinal detachment at Moorfields Eye Hospital between August 2016 and January 2017. Imaging was performed using an SD-OCT (Heidelberg Engineering Co, Heidelberg, Germany) and Optos California ultra-widefield retinal imaging system (Optos, Dunfermline, UK).

Results:

12/30 (40%) retinal holes were judged clinically to have an associated retinal detachment. 5/30 (16.7%) holes had no retinal detachment clinically but associated subretinal fluid on SD-OCT imaging. The remaining 13/30 (43.3%) holes were flat, with minimal or no associated subretinal fluid. 17/17 (100%) retinal holes associated with subretinal fluid or retinal detachment had vitreous attachment at the site of the hole. 14/17 (82.4%) of these had vitreous attachment at both edges of the retinal hole, commonly in a U shape configuration, which appeared to exert traction. 10/13 (76.9%) of flat retinal holes had vitreous attachment, 5/13 (38.5%) of which had vitreous attachment on both sides of the hole, a lower proportion when compared to holes associated with detachment or subretinal fluid (82.4%; p=0.02). 5/13 (38.5%) flat retinal holes had vitreous attachment at only along one edge of the hole. The average adjacent retinal thickness was greater in round hole detachments when compared with flat retinal holes (252.8m vs 143.2m, p=0.005).

Conclusions:

This is the first imaging series of retinal holes associated with retinal detachment. It illustrates that such imaging is not only feasible but shows evidence of vitreous attachment associated with round retinal holes, with or without retinal detachment, which may exert traction. Vitreous attachment at both edges of the retinal hole was more commonly seen in holes associated with subretinal fluid or retinal detachment. Further prospective longitudinal series are needed to assess the relationship between these SD-OCT features and the progression of peripheral round hole retinal detachments.
