Abstract Details

Purpose:

Variations of the anterior interface in the adult eye is currently not well known. With the advent of the intraoperative OCT it is possible to observe this interface more in detail. When performing systematically a PPCCC it is possible to better describe the presence or absence of Wieger’s ligament detachment (also called posterior capsule detachment) and presence or absence of total anterior hyaloid detachment (also called zonular detachment). Our aim of this paper is to study the intraoperative incidence of partial or total, capsule or zonular anterior hyaloid detachment (AVD) after PPCCC.

Setting:

Study was made in UZA - Antwerp University Hospital (Belgium) during my observation in EBO Grant.

Methods:

Intraoperative OCT of 16eyes of 15adult patients (mean age 67,5 years,mostly female) operated for cataract were included in this observational study looking for variations of the attachment/detachment of Wieger’s ligament to the posterior lens capsule. Specifically focus on the segment recorded after emptying the capsule bag from its lens content and filling the anterior chamber with OVD. PPCCC was then performed.Technique consists of making a surgically controlled hole in the posterior capsule through which the retro-capsular area is inflated with OVD.Presence or absence of AVD was recorded and correlated with the following patient’s parameters: keratometry,axial length,anterior chamber depth,age,sex.

Results:

All sixteen eyes presented a certain degree of partial or total anterior hyaloid detachment. 10 eyes out of the 16 had total (capsular and zonular) anterior hyaloid detachment with mean axial length 23,73mm, keratometrics 43,58D and anterior chamber depth 3,36mm.

Conclusions:

In the studied age group, the first risk factor for anterior hyaloid detachment is age followed by axial length and anterior chamber depth. No other parameters showed correlation with AVD. We did not evaluate PVD and as a result cannot give any information how AVD is correlated to PVD in this particular age group. However, we can conclude that AVD is an age-related manifestation.
