Ciliary Body Structures Imaging After Preoperative Anti-inflammatory Treatment by Yassine Alibet, Oleg Zadorozhyy, Galyna Levytska, Nataliya Pasyechnikova, Ukraine


ABSTRACT

Purpose:

To investigate ciliary body dimensions in rhegmatogenous retinal detachment (RRD) complicated by choroidal detachment (CD) after preoperative anti-inflammatory treatment.

Setting:

RRD can be complicated CD and accompanied by hypotony and intraocular inflammation. This is the most unfavorable type of RRD for prognosis and requires a special treatment strategy.

Materials & Methods:

This study included 31 RRD+CD patients (31 eyes) with an intact fellow eye who were under observation. Before the vitrectomy, they received 4,0mg intravitreal triamcinolone (IVT), either alone or in combination with 0.5 to 0.8 mL of perfluorpropane. Near-infrared transpalpebral transillumination (NIRTPT) and ultrasound biomicroscopy (UBM) of anterior eye structures were performed before and 1, 2, 3 or 4 days after preoperative intravitreal therapy.

Results:

Mean baseline width and mean baseline thickness of the pars plicata in eyes with combined RRD and CD were statistically significantly greater than in intact fellow eyes (2.4 ± 0.1 mm versus 1.9 ± 0.1 mm, P = 0.01, and 0.83 ± 0.1 mm versus 0.65 ± 0.1 mm, P = 0.02, respectively). Mean post-treatment pars plana width in the affected eyes having axial length > 25.0 mm was 4.74 ± 0.63 mm, and the percentage of these eyes was 64.5% among eyes with combined RRD and CD. Mean thickness and mean width of the pars plicata in the affected eyes after treatment were 2.2 ± 0.1 mm и 0.66 ± 0.1 mm, respectively.

Conclusions:

First, in eyes with RRD complicated by CD, (1) pars plana detachments were observed, and (2) pars plicata width and thickness were greater than in intact fellow eyes, which may be evidence of intraocular inflammation. Second, ciliary body detachment tend to occur in longer eyes (therefore, those with a greater pars plana width) with RRD complicated by CD. Thus, the percentage of eyes longer than 25 mm (i.e., eyes with a wider pars plana) was 64.5% among eyes with RRD complicated by CD. Finally, in eyes with RRD complicated by CD, there was evidence of re-attachment of the pars plana as well as reduction in pars plicata thickness and width after preoperative anti-inflammatory treatment.
