Abstract
Objective
To study the clinical and visual outcomes of patients presenting with bacillary layer
detachment (BLD) on optical coherence tomography (OCT) in blunt ocular trauma.
Design
Retrospective observational study.
Participants
Clinical fundus photographs and OCT scans with Spectralis machine were reviewed to
identify patients with blunt ocular trauma showing BLD.
Methods
Patients were further analyzed for changes in their anatomic features such as subretinal
hemorrhage, intrabacillary layer bleed. subretinal fibrosis and choroidal rupture
and reattachment of BLD, and visual outcomes over subsequent follow-up visits.
Results
Of a total of 77 eyes with blunt ocular trauma, 6 (8%) eyes with BLD were identified.
All patients were male with presenting visual acuity ranging from 6/9 to 2/60 (mean
logMAR = 1.119; Snellen's equivalent = 20/263). The time interval between trauma and
presentation ranged from 1 to 7 days. Subretinal hemorrhage and choroidal rupture
were noted in all 6 eyes. On OCT, foveal involvement by the BLD was noted in 5 eyes.
Intrabacillary layer hemorrhage was noted in all patients. Reattachment of the bacillary
layer and visual acuity improvement were noted in all eyes at the final visit. The
time interval for resolution of BLD ranged from 2 to 10 days. Visual acuity of 6/36
or less was secondary to subretinal fibrosis close to the fovea and subfoveal choroidal
rupture.
Conclusion
BLD in blunt ocular trauma is a rare finding, shows complete resolution, and appears
not to influence visual or anatomic outcome.
