Consensual eye intra-ocular pressure rise following unilateral glaucoma surgery.

Consensual eye intra-ocular pressure (IOP) increase has been reported following ipsilateral glaucoma surgery. The study evaluated the need for increase in anti-glaucoma medications (AGM) ± glaucoma surgery to control the IOP in consensual eye following unilateral glaucoma surgery. Data of 187 consecutive patients who underwent either trabeculectomy or AGV implant were collected. Index (IE) and fellow eye (FE) IOP (baseline, follow-up day 1, week 1, months 1 and 3), acetazolamide and AGM use, FE surgery, glaucoma status, and relevant ophthalmological data were collected. A significant increase from a baseline IOP of 14.4 mmHg was noted at week 1 (15.8 mmHg, p-0.005) and month 1 (15.62 mmHg, p-0.007) in FE (n-187). Among the 61 patients (33%, n-187) who needed additional intervention to reduce FE IOP, 27 (14.4%) underwent FE trabeculectomy. In the IE trabeculectomy group (n-164), significant increase in FE IOP was noted in week 1 (15.87 mmHg, p-0.014) and month 1 (15.61 mmHg, p-0.02), and in the IE AGV group (n-23) at day 1 (15.91 mmHg, p-0.06). Pre-operative acetazolamide resulted in significant increase in FE IOP at week 1 and month 1. Maximum increase in FE IOP of nearly 3.5 mm Hg was noted when IE IOP was persistently <5 mmHg at one month following surgery. Mean FE IOP remained elevated at all visits. An increase in fellow eye IOP needing any additional intervention in a third and surgical intervention in nearly a sixth meant that FE IOP be strictly monitored and addressed following unilateral glaucoma surgery.
