ABSTRACT
Inflammatory events with highly variable clinical features have been reported with the coronavirus disease 2019 (COVID-19) pandemic, which has affected the whole world. Only one case of COVID-19–associated bilateral acute iris transillumination (BAIT) syndrome has been reported in the literature. We present a case series in which we hypothesize that the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may have a mechanism similar to the common viruses that cause BAIT, the etiology of which is still unknown.
ABSTRACT
AIM: To observe the medium-long-term efficacy of trabeculectomy in the treatment of pigmentary glaucoma(PG).METHODS: The clinical data of 38 patients(51 eyes)who were diagnosed with PG and received trabeculectomy at the Affiliated Hospital of Yunnan University from January 2010 to September 2022 were retrospectively analyzed. The postoperative follow-up ranged from 3 to 144mo. The intraocular pressure(IOP), visual acuity and refractive status were analyzed, complications were recorded and surgical efficacy was evaluated.RESULTS: The average preoperative use of IOP lowering drugs was 2.90±0.12, with a mean IOP of 18.89±7.40mmHg. The IOP at 3d, 1, 3, 6mo, 1a after surgery and the last follow-up visit were 14.68±5.08, 13.99±2.95, 14.25±2.50, 14.36±2.83, 14.33±2.66, 14.94±1.95mmHg, respectively, and postoperative IOP was significantly lower at all time points than that before surgery(P<0.05), while there was no significant difference at all time points after surgery(P>0.05). During the follow-up period, the visual acuity of all patients was stable, and no endophthalmitis or malignant glaucoma occurred. At the last follow-up, the complete success rate was 90%, the qualified success was 8%, and the failure rate was 2%.CONCLUSION: Trabeculectomy is a safe and effective treatment method for PG, which can effectively control the IOP, and stabilize the visual acuity and relieve the reverse pupil block.
ABSTRACT
A 47-year-old male presented with bilateral 4 + circulating pigment in the anterior chamber, diffuse iris transillumination, dilated pupils unresponsive to light, and high intraocular pressure (IOP) levels in both eyes. Visual acuity and IOP improved bilaterally with topical steroid and antiglaucomatous therapy. In the 10th month, bilateral cystoid macular edema (CME) was developed and resolved after subtenon triamcinolone injections. CME recurred after cataract surgery in the right eye which was treated with intravitreal dexamethasone implant injection. CME was recurred in the left eye and treated with intravitreal dexamethasone implant at the same setting with cataract surgery. CME can be seen in the course of bilateral acute iris transillumination (BAIT). This is the first BAIT case presenting with bilateral CME.
