This paper provides the first reported case of acute posterior chamber hemorrhage during fluorescein angiography (FA). This is a case review with serial color photographs of the anterior segment. A 76-year-old male was referred for angiographic control of age-related macular degeneration. He was pseudophakic OU, BCVA 20/40 OU. He had mild hypertension, but not diabetes. He had had two previous angiograms without adverse effects. Difficulty was experienced in obtaining the images owing to a progressive reduction in the transparency of the media. A dense hemorrhage in the posterior chamber of the right eye was found, involving the visual axis. Thorough biomicroscopy, gonioscopy, and ultrasonic biomicroscopy showed that part of one of the haptics of the right intraocular lens (IOL) was touching and tearing the posterior face of the iris, without any visible synechiae, iris, or angle neovascularization. Anterior segment FA and posterior ultrasonography were normal. No similar case has been described in the literature involving dense progressive bleeding located in the capsular bag and posterior chamber, without any detectable triggering ocular event other than mydriasis and fluorescein injection. Contact of the iris or sulcus with part of the intraocular lens, aggravated by the intense use of mydriatics during the FA procedure, probably caused bleeding to happen.

Accidental intraocular lens (IOL) implantation into the corneal stroma is a rare clinical entity that can occur during the wound-assisted technique. In this report, we describe a case of an 81-year-old man who underwent cataract surgery in which the IOL was implanted into the corneal stroma with the wound-assisted technique, and we present changes in anterior segment optical coherence tomography. The IOL was removed and reinserted after widening the incision. Air tamponade was created by intracameral injection. An anterior chamber tap was performed 10 h later to reduce increased intraocular pressure. Interlayer separation of the corneal stroma was confirmed 30 min postoperatively but was corrected 4 days later. The patient’s best-corrected visual acuity (BCVA) was logMAR 0.30, and he had been diagnosed with age-related macular degeneration before surgery. Although the opacity of the corneal stroma persisted, BCVA improved to logMAR 0. When using the wound-assisted technique for IOL insertion, surgeons should take care not to implant the IOL into the corneal stroma.

Abstract Background We report a case of uveitis–glaucoma–hyphema (UGH) syndrome in a highly myopic pseudophakic eye with seemingly normal positioning of a two-haptic intraocular lens (IOL). Case presentation The patient was a 61-year-old woman suffering recurrent episodes of blurred vision, floaters, redness, elevated intraocular pressure (IOP), and pain in the right eye following implantation of a sclera-fixed IOL. The symptoms were alleviated by the systemic and topical administration of IOP-lowering and anti-inflammatory medications. A slit-lamp examination revealed depigmentation and atrophy of the iris, and a quiet anterior chamber in the right eye. Endophthalmitis caused by hypovirulent bacteria and UGH syndrome were both considered. Ultrasound biomicroscopy (UBM) and gonioscopy provided direct evidence of malpositioned IOL haptics, which pushed the root of the iris forward, resulting in persistent mechanical chaffing, the probable cause of UGH syndrome. IOL explantation resolved her symptoms. Negative bacterial culture results for the IOL excluded the possibility of endophthalmitis. Conclusions Heightened awareness of underlying UGH syndrome and prompt UBM are important when doctors encounter a patient with a sclera-fixed IOL suffering from recurrent anterior segment inflammation and elevated IOP.

Purpose Neovascular age-related macular degeneration (ARMD) with retinal angiomatous proliferation (RAP) has a poor natural history and the efficacy of any treatment has not yet been established. The authors describe a combined surgical treatment. Methods A 76-year-old woman presented with a best-corrected visual acuity (BCVA) of 20/600 in the right eye and macula with stage 3 RAP as identified by fluorescein angiography (FA), indocyanine green angiography (ICGA), and optical coherence tomography (OCT). After a standard three-port pars plana core vitrectomy (PPV), endodiathermy of the arteriolar and venous feeder vessels of each lesion was performed, intraretinal RAP feeder vessels were cut with manual vertical intraocular scissors, and 0.1 mL of triamcinolone acetonide (TAAC) was injected intravitreally At 1 and 4 weeks and at the sixth month, the patient underwent a complete eye examination, FA, ICGA, and OCT to assess outcomes and complications. Results Six months later, BCVA was stable at 20/300, intraocular pressure was 15 mmHg, anterior segment and vitreous cavity were clear without evidence of TAAC granules, and retina was attached. FA and ICGA showed a complete occlusion of the RAP and absence of leakage or ischemia and OCT demonstrated decreased macular thickness with resolution of both intraretinal edema and pigment epithelium detachment, and the restoration of the normal macular profile. At the end of follow-up, the authors did not observe any ocular or systemic complication. Conclusions Surgical approach to RAP stage 3 with intravitreal injection of 4 mg of TAAC was safe and anatomically effective.

Intelligent Healthcare

With the advancement of computational power, refinement of learning algorithms and architectures, and availability of big data, artificial intelligence (AI) technology, particularly with machine learning and deep learning, is paving the way for ‘intelligent’ healthcare systems. AI-related research in ophthalmology previously focused on the screening and diagnosis of posterior segment diseases, particularly diabetic retinopathy, age-related macular degeneration and glaucoma. There is now emerging evidence demonstrating the application of AI to the diagnosis and management of a variety of anterior segment conditions. In this review, we provide an overview of AI applications to the anterior segment addressing keratoconus, infectious keratitis, refractive surgery, corneal transplant, adult and paediatric cataracts, angle-closure glaucoma and iris tumour, and highlight important clinical considerations for adoption of AI technologies, potential integration with telemedicine and future directions.
