Early postoperative hypotony and ciliochoroidal detachment after microincision vitrectomy surgery.

Abstract

PURPOSE:

To determine the relationship between a ciliochoroidal detachment and intraocular pressure (IOP) after microincision vitrectomy surgery (MIVS).

DESIGN:

Prospective, consecutive, observational case series.

METHODS:

Thirty eyes of 30 patients with an epiretinal membrane that underwent MIVS were prospectively studied. The intraocular pressure (IOP) was measured before 3-port MIVS, and at 1 minute, 1 and 3 hours, and at 1 day postoperatively. All of the 90 sclerotomies were examined by swept source optical coherence tomography to assess the wound and presence of a ciliochoroidal detachment at 3 hours and at 1 day postoperatively. The mean IOP and closure rate of the sclerotomies were compared between eyes with and without a ciliochoroidal detachment. The correlation between the presence of ciliochoroidal detachment and postoperative IOP was determined.

RESULTS:

The incidence of ciliochoroidal detachment was 63.3% (19 eyes) during the 1-day observation period. The mean postoperative IOPs were significantly lower than the preoperative IOPs in eyes with a ciliochoroidal detachment (P < .05). The mean postoperative IOPs were significantly higher in eyes without a ciliochoroidal detachment than in eyes with a ciliochoroidal detachment (P < .05). The incidence of open sclerotomies was significantly higher in eyes with a ciliochoroidal detachment than in eyes without a ciliochoroidal detachment at 3 hours postoperatively (P = .03).

CONCLUSIONS:

A shallow ciliochoroidal detachment develops in 63.3% of eyes after MIVS. Hypotony at the early postoperative period may be a risk factor for a ciliochoroidal detachment.
