Clinical features, management, and outcomes of expulsive choroidal hemorrhage during cataract surgery: 13-year experience of a tertiary eye center.

PURPOSE: To study the risk factors, clinical features, management, and outcomes of intraoperative expulsive choroidal hemorrhage (ECH) during cataract surgery. SETTING: Aravind Eye Hospital, Madurai, Tamil Nadu, India. DESIGN: Retrospective hospital-based study. METHODS: Of the 1 167 250 patients who underwent cataract surgery between 2008 and 2020, patients diagnosed with intraoperative ECH were included. Demography, ocular and systemic risk factors, visual acuity, type of ocular anesthesia, intraoperative and postoperative records, management, and surgical outcomes were analyzed. RESULTS: 52 eyes (0.004%) of 1 167 250 patients had ECH. Of the 52 cases, 43 cases (incidence rate 0.006%) were reported in the years 2008 to 2015 and 9 cases (incidence rate 0.002%) in the years 2016 to 2020. The change in the ocular anesthesia from peribulbar and retrobulbar anesthesia (2008 to 2015) to sub-Tenon anesthesia (2016 to 2020) was associated with a reduced rate of ECH ( P = .002). 28 eyes (53.8%) experienced limited ECH and 24 eyes (46.2%) full-blown ECH. The visual outcome was better in eyes with limited ECH compared with full-blown suprachoroidal hemorrhage in all follow-up visits. The median vision (interquartile range) before the cataract surgery and at postoperative day 1 were 1.30 (0.78 to 2.60) and 2.45 (1 to 2.75), respectively. The median final vision (interquartile range) after the secondary surgical intervention was 2.2 (0.60 to 2.60). CONCLUSIONS: This series included 52 eyes with ECH, recognized associations of ECH with different types of anesthesia and with different cataract surgical procedures, and described management of ECH. Postoperative visual outcome was poor.

Corneal Cross-linking as an Adjuvant Therapy in the Management of Recalcitrant Deep Stromal Fungal Keratitis: A Randomized Trial.

PURPOSE: To assess the efficacy of corneal cross-linking (CXL) as an adjuvant to appropriate antifungal therapy in nonresolving deep stromal fungal keratitis. DESIGN: Randomized clinical trial. METHODS: Eyes with culture-positive deep stromal fungal keratitis not responding to appropriate medical therapy for a period of 2 weeks were randomized to receive either adjuvant CXL or no additional treatment. Antifungal medical therapy was continued in both groups. The prespecified primary outcome was treatment failure at 6 weeks after enrollment, defined as perforation and/or increase in ulcer size by ≥2 mm. RESULTS: The trial was stopped before full enrollment because of a marked difference in the rate of perforation between the 2 groups. Of the 13 cases enrolled in the study, 6 were randomized to the CXL group and 7 to the non-CXL group. Five eyes in the CXL group and 3 eyes in the non-CXL group experienced treatment failure by 6 weeks (P = .56). In a secondary analysis, the CXL group experienced more perforations than the non-CXL group (4 vs 0, respectively; P = .02). CONCLUSION: CXL used as adjuvant therapy for recalcitrant deep stromal fungal keratitis did not improve outcomes.

The clinical differentiation of bacterial and fungal keratitis: a photographic survey.

PURPOSE: The purpose of this study was to determine whether clinical signs of infectious keratitis can be used to identify the causative organism. METHODS: Eighty photographs of eyes with culture-proven bacterial keratitis or smear-proven fungal keratitis were randomly selected from 2 clinical trials. Fifteen cornea specialists from the F. I. Proctor Foundation and the Aravind Eye Care System assessed the photographs for prespecified clinical signs of keratitis, and they identified the most likely causative organism. RESULTS: Clinicians were able to correctly distinguish bacterial from fungal etiology 66% of the time (P < 0.001). The Gram stain, genus, and species were accurately predicted 46%, 25%, and 10% of the time, respectively. The presence of an irregular/feathery border was associated with fungal keratitis, whereas a wreath infiltrate or an epithelial plaque was associated with bacterial keratitis. CONCLUSIONS: Cornea specialists correctly differentiated bacterial from fungal keratitis more often than chance, but in fewer than 70% of cases. More specific categorization led to less successful clinical distinction. Although certain clinical signs of infectious keratitis may be associated with a bacterial or fungal etiology, this study highlights the importance of obtaining appropriate microbiological testing during the initial clinical encounter.
