Purpose

The study aimed to evaluate the efficacy of ab interno  combined viscodilation and trabeculotomy  with the OMNI Surgical device ( Sight Science)  and the success predictor factors in a comprehensive ophthalmology private practice setting

Setting

Single center, private practice in Maryland USA

Methods

This prospective study included 40 eyes (23 patients) with early and moderate open angle glaucoma. The patients were treated with ab interno combined viscodilation and trabeculotomy. The viscodilation was performed in the inferior 180 degrees, and the trabeculotomy was performed only in the inferior nasal quadrant, either with or without concurrent cataract surgery. The OMNI Surgical System (Sight Sciences) was used in all the cases. 39 eyes had OAG, and 1 eye had pigmentary glaucoma. This study examined pre/post-operative IOP values,  numbers of medications and success predictor factors

Results

Of the  23 patients included  ( 40 eyes ) ,sixty percent of the patients involved were African American.

The mean pre-operative value was 16.8 mmHg, the mean post-operative IOP values were 13.7 mmHg. A mean drop of 3.1 mmHg, including a total of 32 eyes demonstrating a drop. The mean number of medications used pre- operative was 1.6, the mean post-operatively were 0.7 with 76 % of eyes able to decrease the number of drops. 11 eyes had prior SLT and the mean drop of IOP values was 3.9 mmHg.

Most common complication was increased IOP in the post-operative period. Patients demonstrating the largest drops in IOP included those with the with highest IOP at the starting point. Average follow-up for  in this series was 10 months.

Conclusions

The viscodilation in the inferior 180 degrees with trabeculotomy of the inferior nasal quadrant is effective and safe procedure, allowing the preservation of most of TM tissue that can be targeted, if needed, to reduce IOP. SLT seems to have a synergetic effect.
