Abstract
 
Purpose
 

To determine the presence and relationship between annular cilichoroidal detachment (CCD) and early postoperative intraocular pressure (IOP) in non penetrating deep sclerectomy (NPDS) glaucoma surgery.

 
Methods
 

Prospective, observational non-comparative study over thirty two eyes of 32 patients that underwent NPDS. All surgeries were performed with intraoperative antimetabolite agent (mitomycin c 0.2 mg/ ml) and without any intraescleral implant. Patients were examined at 24 hour, 1, 2, 3, 4 and 8 week postoperative follow-up visits by goldman tonometer IOP and swept source optical coherence tomography (SS-OCT). Standarized four sclerolimbar quadrants were analyzed in each visit to detect annular ciliochoroidal detachment with SS-OCT (SS-1000 CASIA; Tomey, Nogoya, Japan). Mean postoperative IOPs were compared between eyes with and without CCD in each visit. Resolution time of CCD reattachment and correlation with factors as: gender, age, type of surgery and corneal pachymetry was also studied.

 
Results
 

The incidence of CCD was 53.1% (17 eyes) in the first 24 hour and decreased progressively to 25% (8 eyes) and 6.2% (2 eyes) in 2 week and 4 week examination respectively. The mean postoperative IOPs were significantly lower (p < 0.05) in eyes with annular CCD comparing to eyes without in the 1 and 2 week follow-up ( 9.6 mm Hg Vs 12.8 mm Hg and 9.0 mm Hg Vs 12.4 mm Hg respectively). Mean period of CCD resolution was 17.2 days ( range 3-59 days). In the multivariate analysis a thinner central corneal thickness was the only factor associated to higher incidence of CCD.

 
Conclusions
 

SS-OCT technology is a non invasive diagnostic tool aproppriate to monitor presence of annular ciliochoroidal detachment postperatively. Ciliochoroidal detachment was present in 53% of NPDS surgeries in the early postoperative visit. Presence of annular CCD is related with lower postoperative IOP in the first 2 weeks follow-up
