RESUMEN
OBJECTIVES: To asses the course of intraocular pressure (IOP) restoration and visual acuity (VA) recovery in eyes with hypotony after trabeculectomy. METHODS: Medical charts of patients undergoing trabeculectomy between January 2017 and June 2019 were reviewed. Cases with hypotony (IOP < 5 mmHg) due to over-filtration in the early postoperative period were assessed retrospectively. Primary outcome measures included change in IOP and VA in the postoperative period and percentage of eyes with hypotony on each follow-up. RESULTS: Thirty-five eyes of 31 patients (23 male, 8 female) were included. The mean follow-up was 18.3 ± 6.9 months. The mean IOP was 3.0 ± 3.2, 9.2 ± 6.2, 9.4 ± 5.6, 9.4 ± 4.0, 10.9 ± 3.6 and 10.2 ± 3.3 mmHg at week 1, months 1, 3, 6, 12 and last follow-up, respectively. Out of 35 hypotonic eyes, 8 (22.8%) had prolonged hypotony at month 1, 4 (11.4%) at month 3, 1 (2.9%) at month 6. The decrease in VA continued to be significant at months 1 and 3 (p = 0.015, p = 0.036, respectively) and returned to baseline after the sixth month (p > 0.524). CONCLUSIONS: In eyes with early hypotony after trabeculectomy while low IOP recovers at first month, it takes longer for the visual restoration. The postoperative month 1 appears to be decisive for recovery of hypotony.

PRCIS: Retinal nerve fiber layer (RNFL) thickness is helpful in the diagnosis of glaucoma in myopic eyes but neuroretinal rim (NRR) thickness is the most valuable measure. However, changes in optical coherence tomography angiography (OCT-A) parameters are insufficient for the diagnosis of mild to moderate glaucoma in myopia. PURPOSE: To detect how a multimodal evaluation, which includes RNFL, NRR thickness, and optic nerve head (ONH) OCT-A, affects glaucoma diagnosis in myopic patients. MATERIALS AND METHODS: Parameters of healthy myopic and myopic glaucoma eyes with an axial length of ≥24 mm were compared. The ONH structural features and peripapillary RNFL thickness were determined with Cirrus 5000 HD-OCT (Cirrus HD-OCT; Carl Zeiss Meditec, Dublin, CA). The Cirrus 5000 HD-OCT with AngioPlex was utilized to perform OCT-A imaging. The sensitivity and specificity levels were calculated by the best cut-off values with area under curve (AUC). RESULTS: One hundred healthy myopic and 54 myopic glaucoma eyes were evaluated. In all areas, myopic glaucoma patients exhibited lower RNFL and NRR thickness than healthy myopic individuals ( P <0.05), with the exception of nasal quadrant RNFL thickness ( P =0.152). The mean entire and 4 quadrants of global radial peripapillary capillary (RPC)-perfusion and global RPC flux index (FI) were significantly lower in the group of myopic glaucoma patients except for the nasal quadrant mean RPC perfusion ( P =0.224). The average RNFL and NRR thickness had a significant difference in AUC for the diagnosis of glaucoma in myopic individuals ( P =0.001, for each). The average NRR showed excellent diagnostic performance, whereas the average RNFL showed good diagnostic performance. Average RPC perfusion and average RPC FI showed poor diagnostic ability. The average NRR AUC was more significant than average RPC perfusion and average RPC FI AUC ( P <0.001). CONCLUSIONS: Although RNFL thickness was helpful to diagnose glaucoma in patients with myopia, the diagnostic power of NRR thickness performed best. OCT-A parameters showed poor diagnostic accuracy for glaucoma and the observed perfusion decrease in myopic glaucoma eyes was not sufficiently discriminative compared with NRR and RNFL thickness measurements.

Objectives: To determine and evaluate the rate of diplopia after Ahmed glaucoma valve (AGV) implantation surgery. Materials and Methods: The records of patients who underwent AGV implantation in our hospital between the years of 2010 and 2017 were retrospectively reviewed. Patients who were referred to our strabismus department due to binocular diplopia after AGV implantation surgery were included. The details of postoperative day 1, day 7, day 15, and 1 month examinations were recorded. In the postoperative period, the onset time of diplopia complaints, diplopia type, and the presence of diplopia at distance and near fixation were noted. Ocular motility examination and deviation measurements were evaluated. Results: Ten (47%) of 211 patients who underwent AGV implantation in our hospital between 2010 and 2017 met the study inclusion criteria. Six of the 10 patients were men (60%) and 4 were women (40%). The mean age of the patients was 44.5 (34-63) years. Complaints of diplopia developed at a mean of 14.5±12.3 (1-30) days after AGV implantation. The prism measurements of the patients were found to be 8.4±1.4 prism diopters (PD) exotropia and 7.1±8.8 PD hypotropia. While 8 patients had diplopia only at near distance, 2 patients had diplopia at both distance and near. Three patients were treated with prismatic glasses, and their complaints of diplopia recovered spontaneously in 5.11±4.10 months. The other 7 patients were followed up without treatment, and their diplopia complaints resolved spontaneously in 6.11±4.40 months. Conclusion: Although most of the diplopia that develops after AGV implant surgery resolves without treatment, prismatic glasses might be considered as a treatment option in patients whose diplopia affects their daily lives.

Purpose: To evaluate the prescribing habits of glaucoma specialists and of general ophthalmologists, and reveal the conformance with European Glaucoma Society (EGS) guidelines in the medical treatment of primary open-angle glaucoma (POAG) and ocular hypertension (OHT). Methods: Patients receiving medical treatment for POAG/OHT in the glaucoma clinic comprised the "naive group." Patients having a diagnosis and a treatment for POAG/OHT initiated in another center before presentation comprised the second group and were named as "treatment initiated elsewhere" (TIEW). All patients were retrospectively evaluated from the patients' charts. The outcome measures included the percentage of eyes treated with monotherapy, the molecule groups preferred, and the change in prescription trends over the years in both groups. Results: Seventy-two subjects were included in the naive group and 135 subjects in TIEW group. The rate of monotherapy was 76% and 36% in both groups, respectively. The molecule number was significantly higher in the TIEW group compared with naive group (1.98 ± 0.89 vs. 1.28 ± 0.56, P < 0.001). Until 2003, beta blockers, and in the 2003-2008 period, prostaglandin analogs (PGAs) were the mostly prescribed drugs in glaucoma clinic. From 2009, the rate of PGAs declined, with PGAs being replaced by combination drugs and alfa-2 agonists. Conclusions: Overtreatment rate was high among patients receiving a diagnosis and a treatment by general ophthalmologists, whereas glaucoma specialists were found to conform with EGS guidelines. A shift toward polypharmacy was observed from 2000 to 2017. The common guidelines to evaluate and treat glaucoma need to be adopted by the general ophthalmologists in their real-life practice.

PURPOSE: To compare results of three different tendon transposition techniques (Knapp procedure and two modified techniques) for the treatment of type 2 monocular elevation deficiency (MED) patients. METHODS: The medical records of patients with MED type 2 operated on at a single institution from 2000 to 2016 were reviewed retrospectively. Patients were divided into three vertical transposition groups: (1) full tendon width, (2) augmented surgery; and (3) partial tendon width. Surgical success was defined as no severe limitation of upgaze, hypotropia of <6Δ, and no hypertropia in primary position. Pre- and postoperative vertical deviations in the primary position and limitations in elevation levels were compared. RESULTS: A total of 39 patients were included. The pre- and postoperative deviations in the full-tendon group were 22.50Δ ± 4.17Δ and 3.50Δ ± 1.27Δ, respectively; in the augmented surgery group, 23.75Δ ± 4.78Δ and 1.75Δ ± 1.14Δ; and in the partial-tendon group, 20.50Δ ± 3.98Δ and 4.12Δ ± 2.78Δ. Corrected vertical deviations were 19Δ, 23Δ, and 16Δ, respectively. The pre- and postoperative limitation of elevations were -2.80 and -0.80 in the full-tendon group, -3.20 and -0.90 in the augmented surgery group, and -2.37 and -1.12 in the partial-tendon group. The pre- and postoperative vertical deviation improvements and limitations of elevation were statistically significant (P < 0.05) in all groups. Success was achieved in 29 patients (74%). CONCLUSIONS: In this study cohort, all three procedures were reasonably effective in improving vertical deviations and limitation of elevation.

Purpose. To describe our surgical technique in the management of pseudophakic malignant glaucoma refractory to conventional treatment. Methods. Two pseudophakic eyes with malignant glaucoma underwent peripheral iridectomy, lens capsulectomy, hyaloidectomy, and anterior vitrectomy through a clear corneal incision by using a vitreous cutter. Results. Prompt resolution of malignant glaucoma was achieved in both cases and no recurrence was observed during postoperative followup of five months. Conclusions. An anterior segment surgeon can treat pseudophakic malignant glaucoma successfully by using a vitreous cutter inserted through a corneal incision and performing peripheral iridectomy, capsulo-hyaloidectomy, and anterior vitrectomy.
