Surgical management of retinal detachments related to coloboma of the choroid1☆,

Materials and methods
This is a retrospective study of 85 eyes of 81 patients (58 males and 23 females) who presented to us between January 1987 and May 1996. All patients had retinal detachments related to coloboma of the fundus. The retinal detachments were attributed to the coloboma if there was extension of the detachment within the border of the coloboma. A break in the intercalary membrane often was identifiable preoperatively or intraoperatively. Four patients were operated on in both eyes for a similar
Results
Of the 85 eyes that were operated on, 5 had gas tamponade and 80 had silicone oil tamponade. Recurrent retinal detachments occurred in a total of 16 eyes: 3 of 5 eyes with gas tamponade and 13 of 80 eyes with silicone oil tamponade. The recurrence was caused by PVR in 13 eyes (15.3%), new retinal break outside the coloboma in 1 eye (1.2%), and leak from the break in the coloboma due to inadequate chorioretinal adhesion around the coloboma in 2 eyes (2.4%). Revision surgery involved membrane
Discussion
Retinal detachments caused by coloboma of the fundus are relatively rare. The treatment of these patients had been difficult with external scleral buckling techniques as evidenced by the reported poor results.3 This is because of the difficulty in identifying and closing the causative retinal breaks. To develop a rational approach for the treatment of these patients, one has to understand the pathogenesis clearly. Hermann Schubert,11 describing the histopathology of the colobomatous border in

2021, Ophthalmology RetinaCitation Excerpt :The current study found that MICM and CICM schisis occurred at the coloboma margin, and its association with the vitreous traction was confirmed, which had been difficult to observe by histopathologic examination because of the use of autopsied colobomatous eyes. Although a few studies have reported abnormal vitreous structures in coloboma,6,8,12 to the best of our knowledge, no SS OCT or histopathologic study has reported an association between the MICM and CICM schisis and vitreous traction in coloboma. The previously documented sub-ICM space or ICM detachment by SS OCT studies1,6,8–10 possibly included MICM or CICM schisis, which was differentiated clearly based on the POR location, in the current study.
