As-Oct Guided Management Of Corneal And Anterior Chamber Foreign Bodies

To delineate the role of AS-OCT in the identification of the type,location,depth of foreign body (FB) along with the presence of descemet’s membrane (DM) integrity,and management

In a retrospective clinical study, 6 eyes of 6 patients where  foreign bodies were present either  intra-corneal or anterior chamber were included.The foreign bodies were namingly glass,metal,graphite ,gun pellet,human hair,caterpillar hair.AS-OCT helped in delineating the site,location,type of foreign bodies ,the DM integrity especially in cases where the either the patient was unco-operative for examination due to young age  or cornea was edematous or necrotic hampering visualization of the anterior chamber details.After confirming the location of FB ,management was planned in the form of removal either via external,internal approach or combined  approach

The mean age of patients was 29.3 (7–53) years. 5 were male, and one female. All patients had a positive history of injury,one  had a history of insect fall in his eye. Descemet’s membrane (DM) breach was suspected in three cases of deep FB, which was later confirmed on ASOCT. In two cases, DM was presumed to be intact clinically, but ASOCT showed an AC penetration. The FB was removed in five patients.2 via an internal approach, and three via a combined approach.

AS-OCT enables non‑invasive rapid imaging of ocular tissue at various depths, provides an accurate assessment of FB characteristics,  for diagnosis and management of deep corneal FB.
