RESUMEN

Aim: Angioid streaks (ASs) are a rare retinal condition and compromise visual acuity when complicated with choroidal neovascularization (CNV). They represent crack-like dehiscences at the level of the Bruch's membrane. This objective narrative review aims to provide an overview of pathophysiology, current treatment modalities, and future perspectives on this condition. Materials and Methods: A literature search was performed using "PubMed", "Web of Science", "Scopus", "ScienceDirect", "Google Scholar", "medRxiv", and "bioRxiv." Results: ASs may be idiopathic, but they are also associated with systemic conditions, such as pseudoxanthoma elasticum, hereditary hemoglobinopathies, or Paget's disease. Currently, the main treatment is the use of anti-vascular endothelial growth factors (anti-VEGF) to treat secondary CNV, which is the major complication observed in this condition. If CNV is detected and treated promptly, patients with ASs have a good chance of maintaining functional vision. Other treatment modalities have been tried but have shown limited benefit and, therefore, have not managed to be more widely accepted. Conclusion: In summary, although there is no definitive cure yet, the use of anti-VEGF treatment for secondary CNV has provided the opportunity to maintain functional vision in individuals with AS, provided that CNV is detected and treated early.

RESUMEN

PURPOSE: To report a case of bilateral panuveitis following local treatment with Bacille Calmette-Guérin (BCG) immunotherapy for superficial bladder carcinoma. DESIGN: Case report and literature review. METHODS: A 70-year-old female presented with severe bilateral anterior chamber inflammation 5 days after intravesical BCG instillation. Despite topical steroids and mydriatics, inflammation worsened and bilateral optic nerve swelling developed. RESULTS: Oral corticosteroids settled the ocular inflammation, and optic nerve function recovered. A trial of steroid cessation caused rebound uveitis, so she remains on maintenance doses of oral corticosteroid. CONCLUSIONS: Ocular inflammations following BCG therapy for bladder cancer are rare, and little is known about the management of such cases. This is the first report of bilateral panuveitis with optic nerve edema following such treatment.

RESUMEN

PURPOSE: Monocanalicular intubation offers potential advantages over bicanalicular intubation including ease of removal and use of only one canaliculus. Recent reports suggest equal outcomes with both types of tubes for nasolacrimal intubation. This study aimed to evaluate the outcome of monocanalicular intubation during external dacryocystorhinostomy. METHODS: Fifty-seven lacrimal systems of 54 adults with primary acquired nasolacrimal duct obstruction were prospectively randomized into two cohorts for either bicanalicular intubation (n = 29) or monocanalicular intubation (n = 28) during external dacryocystorhinostomy. All subjects had their symptoms evaluated subjectively according to a modified Munk scale and objectively by the dye disappearance test along with probing and irrigation, pre- and post-operatively. Complete success was defined as a total disappearance of symptoms, partial success as an improvement with some residual symptoms, and failure as an absence of improvement or worsening of symptoms at the last follow-up. Patients with concurrent lid or ocular pathology were excluded. RESULTS: Bicanalicular subjects had a significantly higher complete success rate (21/29, 72.4%) compared to the monocanalicular group (12/28, 42.9%) (p = 0.03). Complications included 3 slit punctuae and 2 early tube removals with bicanalicular intubation; 6 temporary superficial punctate keratopathies, 1 punctal stenosis and 4 premature tube losses occurred with monocanalicular intubation. CONCLUSIONS: Patients with monocanalicular intubation during external dacryocystorhinostomy had a significantly lower success rate than patients with bicanalicular intubation in the treatment of nasolacrimal duct obstruction.

RESUMEN

OBJECTIVE: To evaluate the use of the Human Reliability Analysis of Cataract Surgery tool to identify the frequency and pattern of technical errors observed during phacoemulsification cataract extraction by surgeons with varying levels of experience. DESIGN: Observational cohort study. Thirty-three consecutive phacoemulsification cataract operations were performed by 33 different ophthalmic surgeons with varying levels of operative experience: group 1, fewer than 50 procedures; group 2, between 50 and 250 procedures; and group 3, more than 250 procedures. Face and content validity were surveyed by a panel of senior cataract surgeons. The tool was applied to the 33 randomized and anonymous videos by 2 independent assessors trained in error identification and correct tool use. Task analysis using 10 well-defined end points and error identification using 10 external error modes were performed for each case. The main outcome measures were number of errors performed per task, nature of performed errors (executional or procedural), and surgical experience of operating surgeon. RESULTS: Analysis of 330 constituent steps of 33 operations identified 228 errors, of which 151 (66.2%) were executional and 77 (33.8%) were procedural. The overall highest error probability was associated with sculpting, followed by fragmentation of the nucleus; this was most evident in group 1. Surgeons in group 3 proportionally performed more errors during removal of soft lens matter than those in group 1 or 2. Surgical experience had a significant effect on the number of errors, with a statistically significant difference among the 3 groups (P < .001). CONCLUSIONS: The Human Reliability Analysis of Cataract Surgery tool is useful for identifying where technical errors occur during phacoemulsification cataract surgery. The study findings, including the high executional error rate, could be used to enhance and structure resident surgical training and future assessment tools. Face, content, and construct validity of the tool were demonstrated.

RESUMEN

Intrapalpebral migration is a rare complication of hard contact lens use. We report a case of a 52-year-old man who presented with right upper eyelid ptosis and requested cosmetic correction. He had no ocular history apart from myopia, which was corrected with the use of hard contact lenses. Prior to the ptosis he recalled losing his right contact lens during a bout of sneezing. He replaced the missing lens and continued to wear contact lenses as usual. After careful clinical examination, an ipsilateral small, mobile eyelid mass was detected, and orbital MRI verified the suspected presence of a hard contact lens. Following surgical removal and ptosis correction, the patient made a full recovery. The phenomenon of hard contact lens migration in the periocular tissues has been reported in the literature before, but most patients experienced symptoms of variable severity. In this patient, however, there were no symptoms to indicate the presence of a contact lens. This case highlights the importance of including intrapalpebral contact lens migration in the differential diagnosis of an eyelid mass or ptosis in patients.

RESUMEN

The use of membrane-peeling vitreoretinal forceps to facilitate lacrimal sac dissection in external dacryocystorhinostomy is demonstrated. The closed vitreoretinal forceps are advanced via the upper punctum and canaliculus, through to the lacrimal sac. They are then opened maximally providing two points of elevation. This maneuver allows for easier identification of the plane of dissection during lacrimal flap creation. It is especially useful with complex anatomy and for junior trainees in helping to orient the dissection. No tissue or instrument damage has been noted, and because many ophthalmic units have a vitreoretinal service, the forceps may be readily available at no extra cost.
