Successful resolution of serous macular detachment following glaucoma-filtering surgery alone for acquired optic disc pit maculopathy.

PURPOSE: To describe a case of acquired glaucomatous optic disc pit-related maculopathy successfully treated with glaucoma filtering surgery alone. CASE DESCRIPTION: A 67-year-old male was diagnosed with advanced primary open angle glaucoma in both eyes, with a cup: disc ratio of 0.85 in the right eye and 0.95 in the left eye. Visual acuity at presentation was 20/60, and intraocular pressure was 14 mm Hg in the left eye. The fundus of the left eye revealed a serous macular retinal detachment due to an acquired optic disc pit. RESULTS: The left eye of the patient underwent combined cataract and glaucoma filtering surgery. The serous macular detachment resolved completely 15 months after surgery, with a documented visual acuity of 20/40 and intraocular pressure of 10 mm Hg without the use of additional antiglaucoma medications. There was no recurrence of serous macular detachment even after the two-year follow-up visit. CONCLUSION: This case demonstrates that controlling intraocular pressure alone resulted in complete resolution of serous macular detachment in acquired optic disc pit maculopathy without the need for pars plana vitrectomy.

Factors affecting corneal deformation amplitude measured by Corvis ST in eyes with open-angle glaucoma.

PURPOSE: To evaluate the factors affecting corneal deformation amplitude (DA) measured using Corvis ST in eyes with open-angle glaucoma. METHODS: This prospective, longitudinal study included 48 eyes with open-angle glaucoma who required additional intraocular pressure (IOP)-lowering drops. All eyes underwent a complete eye examination at baseline, including a Corvis ST, which was repeated 4-8 weeks after the change in therapy. Factors affecting the corneal biomechanics, namely the DA, were determined using mixed effect models. RESULTS: The mean age of the cohort was 65.0 ± 7.9 years. The mean IOP reduced from 23.4 ± 5.4 mmHg to 17.9 ± 5 mmHg after the change in glaucoma treatment ( P < 0.001). The DA increased from 0.89 ± 0.16 mm to 1.00 ± 0.13 mm after IOP reduction ( P < 0.001). On mixed effect model analysis, IOP (-0.02 ± 0.001, P < 0.001) and corneal pachymetry (-0.0003 ± 0.0001, P = 0.02) affected the change in the DA. CONCLUSION: IOP and corneal pachymetry affect the DA and must be accounted for when using Corvis ST to evaluate corneal biomechanics in glaucoma.
