Bilateral Acute Depigmentation of Iris (BADI) and Bilateral Acute Iris Transillumination (BAIT)Following Acute COVID-19 Infection.

PURPOSE: To report the presenting features and outcomes in patients who developed bilateral acute iris transillumination (BAIT) or bilateral acute depigmentation of iris (BADI) following acute COVID-19 infection. METHODS: Thirty two eyes of 16 patients were reviewed retrospectively. The severity of COVID-19 infection, use of antibiotics, time of onset of ocular symptoms; ocular signs, the course and surgical procedures were recorded. RESULTS: 24 eyes of 12 BAIT and eight eyes of four consecutive BADI patients were included. The mean time between infection and onset of ocular symptoms was 2.5±1.1 weeks. Nine patients were treated with oral moxifloxacin for COVID-19 prior to presentation. Trabeculectomy was performed in 7 eyes (21.8%) of 5 BAIT patients; in the postoperative follow-up, IOP was controlled without medication in 6 eyes, with medication in 1 eye. CONCLUSION: BADI and BAIT can also develop after COVID-19 infection. A significant proportion of BAIT patients may require glaucoma surgery.

Comparison of the 1-year postoperative results of phacoemulsification-trabeculectomy and phacoemulsification-ExPRESS miniature shunt combined surgeries.

BACKGROUND AND OBJECTIVE: This study aimed to compare the 1-year postoperative phacoemulsification-trabeculectomy (P-Trab) and phacoemulsification-ExPRESS® (P-200 model) miniature shunt (P-ExPRESS) combined surgeries. MATERIALS AND METHODS: This retrospective, comparative clinical study investigated 41 eyes of 41 patients diagnosed with open-angle glaucoma and cataract. Of these, 21 eyes underwent P-Trab surgery and 20 eyes underwent P-ExPRESS surgery. The 1-year follow-up results, including intraocular pressure (IOP), visual acuity (VA), medications, and complications, were reviewed and compared. A 5 ≤ IOP ≤ 18 mmHg or 30% reduction from baseline was defined as Qualified Success (QS-1), and target IOP without medication was defined as Complete Success (CS-1). A 5 ≤ IOP ≤ 15 mmHg or 40% reduction from baseline was defined as Qualified Success (QS-2), and target IOP without medication was defined as Complete Success (CS-2). RESULTS: The mean follow-up time was 16 months (12-26 months). Results after the twelfth month for P-Trab versus P-ExPRESS are: CS-1: 42.8% versus 60.0% (P = 0.354); QS-1: 86.7% versus 95% (P = 0.606); CS-2:33.3% versus 40% (P = 0.751); QS-2: 66.6% versus 75% (P = 0.733). Kaplan-Meier survival analysis was not statistically significant between two groups for both QS-1, CS-1 and QS-2, CS-2 (P = 0.329 vs P = 0.365, P = 0.765 vs P = 0.789, respectively). Pre-op mean IOP was: 33.19 ± 8.7 versus 34.55 ± 11.3 mmHg; post-op mean IOP was: 15.19 ± 3.07 versus 15.30 ± 3.32 mmHg (P = 0.913); pre-op mean VA was: 1.17 ± 1.04 versus 1.15 ± 1.07 logMAR; and post-op mean VA was: 0.61 ± 0.80 versus 0.66 ± 0.99 logMAR (P = 0.869). The pre-op mean number of antiglaucomatous medications was 3.76 ± 0.53 versus 3.30 ± 1.45, and the post-op results were 1.52 ± 1.53 versus 0.85 ± 1.26 (P = 0.135). Comparing the pre-op and post-op values, both types of surgeries were equally effective (P = 0.00). Surgical failure was 14.2% (3/21) versus 5% (1/20), and the incidence ratios of significant complications were: 47% (10/21) versus 10% (2/20) and P-Trab versus P-ExPRESS, respectively (P = 0.015). CONCLUSION: The 1-year postoperative results suggest that P-ExPRESS is as effective as P-Trab, with fewer complications.

Long-term Results of Trabeculectomy With Mitomycin-C in Patients With Bilateral Acute Iris Transillumination.

PRéCIS:: The present study suggests that immediate trabeculectomy with mitomycin C (MMC) may be performed as a safe and effective intervention in the management of refractory ocular hypertension (OHT)/glaucoma in patients with bilateral acute iris transillumination (BAIT). PURPOSE: To report the long-term results of trabeculectomy with MMC in the management of OHT/glaucoma in patients with BAIT. MATERIALS AND METHODS: In total, 9 eyes of 6 patients with BAIT who underwent trabeculectomy with MMC between 2007 and 2015 were reviewed. Main outcome measures were control of intraocular pressure (IOP), the number of antiglaucomatous medications required to achieve the desired IOP, and complications. RESULTS: The postoperative follow-up time ranged between 2 and 9.5 years. IOP at presentation was >21 mm Hg in all patients. Maximum IOP with maximum antiglaucomatous medications during follow-up before surgery ranged between 36 and 55 mm Hg. At last visit, IOP ranged between 8 and 17 mm Hg, and 6 of 9 of the eyes required no antiglaucomatous medications. There was no failure in any patients according to the guidelines of the World Glaucoma Association. The most common complication was cataract formation in 7 eyes. CONCLUSIONS: The favorable outcomes observed during 2 to almost 10 years following surgical intervention are encouraging. Therefore, trabeculectomy with MMC provides long-term safe and effective results in OHT/glaucoma in patients with BAIT.

Surgical Outcomes in Radiation-induced Cataracts After External-beam Radiotherapy in Retinoblastoma.

OBJECTIVES: To investigate visual outcomes, surgical complications and tumor recurrence among children with retinoblastoma undergoing phacoemulsification and posterior chamber intraocular lens (PCIOL) implantation for radiation-induced cataract secondary to external beam radiotherapy. MATERIALS AND METHODS: The medical records of all patients treated by phacoemulsification and PCIOL implantation for radiation-induced cataract after external beam radiotherapy for retinoblastoma at a single institution between 1980 and 2014 were reviewed retrospectively. The study included 6 eyes of 6 children (4 girls, 2 boys). RESULTS: Four patients had bilateral and two patients had unilateral retinoblastoma. The median age at diagnosis of retinoblastoma was 28.3 months (range, 12-96 months). All patients received chemoreduction (OPEC protocol) and external beam radiotherapy with or without local ophthalmic therapies and developed radiation-induced cataracts. The median interval from retinoblastoma diagnosis to cataract surgery was 96.3 months (range, 73-122 months). Time interval between surgery and last retinoblastoma treatment was 67.2 months. Postoperative complications included iridocyclitis in 2 eyes and posterior capsule opacification in all eyes. The mean follow-up after surgery was 105.8 months (range, 59-120 months). Final visual acuity was better in all eyes than preoperative visual acuities. CONCLUSION: Phacoemulsification and PCIOL implantation is an effective method of managing radiation-induced cataracts in eyes with previously treated retinoblastoma. However, visual acuity was limited by the presence of primary macular tumor.

Silent polypoidal choroidal vasculopathy in a patient with angioid streaks.

We present a case of silent polypoidal choroidal vasculopathy (PCV) in a patient with angioid streaks. PCV was detected during a routine ophthalmic examination and confirmed by fluorescein angiography, indocyanine green angiography, and optical coherence tomography. After 2 years of follow-up, the PCV remained silent without any complications. We report this rare coexistence and review literature on this topic.

Focal Choroidal Excavation.

Focal choroidal excavation is a choroidal pit that can be detected by optical coherence tomography. Central serous chorioretinopathy, choroidal neovascularization and polypoidal choroidal vasculopathy are pathologies associated with focal choroidal excavation. In this article, we present the follow-up and treatment outcomes of three eyes of two patients with focal choroidal excavation.
