“…More recently, a significant increase in LT (0.07 ± 0.1 mm) was reported six months after trabeculectomy with MMC . These small changes may indicate early cataract formation or progression, which is a common complication after trabeculectomy . An increase in LT may be partly responsible for the reported ACD reduction after trabeculectomy.…”

Trabeculectomy is the most common surgical procedure for the management of glaucoma, which may significantly influence ocular biometry. Axial length and anterior chamber depth tend to decrease, while crystalline lens and choroidal thickness increase post-operatively. An increase in with-the-rule astigmatism is also observed after the procedure. Such biometric changes affect intraocular lens power calculation even years after the procedure. Non-contact biometric methods and postponing cataract surgery after trabeculectomy could reduce calculation errors associated with surgically induced alterations in ocular biometrics.

“…Its risk factor has been reported advanced age, a history of coronary artery disease, postoperative severe hypotonia, and split fixation on VF tests (7,11,13). Even though IOP decreases to normal after filtration surgery, VF loss may persist (14). To demonstrate progression in advanced glaucoma, 10-2 VF test offers better results than 24-2 VF test in assessing rates of mean deviation (MD) changes (15).…”

Evaluation of Sudden Visual Loss and Central 10-Degree Visual Field Change Following Glaucoma Surgery in Severe and End-Stage Eyes

Objectives:The purpose of the study was to evaluate the sudden visual loss and central 10-degree visual field (VF) change following glaucoma surgery in eyes with severe and end-stage glaucoma. Methods: This was a single-center retrospective study. The charts of patients with severe and end-stage glaucoma who had undergone trabeculectomy and Ahmed glaucoma valve (AGV) implantation surgery were reviewed. Patients who had 10-2 Humphrey VF automated (HVFA) at follow-up were included and classified into two following groups: With split fixation on 10-2 HVFA before surgery split fixation group (SFG) and those without split fixation (WSFG). Results: The data of 37 patients in SFG and 28 patients in WSFG were reviewed. The mean follow-up duration was 2.06±0.24 years in SFG and 2±0.3 years in WSFG. 10-2 HVFA revealed that SFG had a mean MD -25.8±5.2 dB preoperatively and -25.2±1.1 dB (p=0.18) at last visit, WSFG had a mean MD −9.8±4.8 dB preoperatively and −10.8±1.5 dB at last visit (p=0.10). In SFG, the mean intraocular pressure (IOP) decreased from 30.1±9.5 mmHg to 12.3±0.62 mmHg (p<0.001), and in WSFG, the mean IOP decreased from 30±6.9 mmHg to 12.3±0.90 mmHg at last visit (p<0.001). There was no statistical difference for visual acuity of both the groups at the follow-up (p=0.30 and p=0.70). In SFG, one patient had wipe-out phenomenon who had undergone AGV surgery. Conclusion: Although wipe-out phenomenon was a rare complication, it can develop not only after trabeculectomy but also after AGV surgery, and patients with split fixation and severe and end-stage glaucoma were at risk for this phenomenon regardless of the type of surgery. Both trabeculectomy and AGV surgery appear to provide stability of the central 10° VF.

To examine the prognosis for the fellow eye of patients with severe visual field loss in 1 eye from chronic forms of open-angle glaucoma, and to identify risk factors for visual field progression in such eyes. Methods: Review of 36 patients followed in an academic medical center with monocular severe visual field loss (Advanced Glaucoma Intervention Study score Ն12) from open-angle glaucoma either at initial Humphrey visual field testing or during follow-up. Change in Advanced Glaucoma Intervention Study visual field score and clinical evaluation were used to determine visual field progression. Kaplan-Meier survival analysis and Cox proportional hazards survival regression were used to estimate visual field progression in fellow eyes and assess possible risk factors. Results: During 67 ± 32 months (mean ± SD), 12 of 36 first-affected eyes (33%) and 6 fellow eyes (17%) had significant visual field progression. The Kaplan-Meier estimate of visual field progression in the fellow eye was
