Abstract
Purpose:
To evaluate the surgical success of combined pars plana vitrectomy with gas tamponade and posterior glaucoma tube placement for patients with Fuchs Heterochromic Iridocyclitis complicated by secondary glaucoma.
Methods:
Nonrandomized, interventional, retrospective clinical study of 14 eyes in 12 patients diagnosed with secondary glaucoma and Fuchs Heterochromic Iridocyclitis. De-identified information of patients who underwent pars plana vitrectomy with gas tamponade and posterior glaucoma tube placement between 1995-2013 were reviewed. Outcome measures included final intraocular pressure, number of glaucoma medications, incidence of post-operative complications such as hypotony and choroidal detachments, and change in visual acuity. Mean follow up time was 55.2 months for 12 of the eyes; two eyes were followed for 14 years.
Results:
All 14 patients have been followed from the date of surgery through present. Average intraocular pressure decreased from an average preoperative level of 36.8 mmHg to 12.14mmHg postoperatively (p<0.00000593). The mean number of glaucoma medications used per patient preoperatively was 2.9 and following surgery decreased to an average of 1 (p < 0.000073). Seven eyes (50%) did not require any medications post operatively. The overall success rate was 100% at one and two years. Visual acuity was improved or maintained within one line of vision in 78% of eyes. There were no surgical failures and no cases of choroidal effusion or detachment. Complications included one eye which developed late ocular hypotony and one patient who developed corneal edema.
Conclusions:
: Combined pars plana vitrectomy with gas tamponade and glaucoma tube placement is a safe and effective procedure to decrease intraocular pressure in patients with Fuchs Heterochromic Iridocyclitis.
