    This study evaluated three glaucoma surgeries for eyes with blocked drainage angles unresponsive to prior treatments. The Benedikt and La Roca techniques showed limited success, while the Nesterov operation was ineffective in these challenging secondary glaucoma cases.

    Area of Science:

    • Ophthalmology
    • Glaucoma Research
    • Surgical Interventions

    Background:

    • Secondary glaucoma with goniosynechias presents a significant challenge.
    • Eyes with refractory glaucoma often have a history of multiple failed conventional surgeries.
    • Obstructive glaucoma requires advanced surgical considerations.

    Purpose of the Study:

    • To assess the efficacy of three surgical techniques for secondary obstructive glaucoma.
    • To evaluate outcomes in patients with a history of failed antiglaucoma operations.
    • To compare the Benedikt, La Roca, and Nesterov operations in refractory cases.

    Main Methods:

    • Surgical intervention on 20 eyes with secondary glaucoma due to goniosynechias.
    • Application of Benedikt operation (10 eyes), La Roca technique (7 eyes), and Nesterov operation (3 eyes).

  • Assessment of intraocular pressure control post-surgery, with target <24 mmHg with medication.

    • Main Results:

    • The Benedikt operation achieved target intraocular pressure in 3 of 10 eyes.
    • The La Roca technique was effective in 3 of 7 eyes.
    • The Nesterov operation failed to lower intraocular pressure in all 3 eyes treated.

    Conclusions:

    • Conventional glaucoma surgeries are often ineffective for eyes with goniosynechial blockage.
    • The Benedikt and La Roca operations demonstrate limited efficacy in this patient cohort.
    • The Nesterov operation showed no effectiveness for secondary obstructive glaucoma in this series.
