CT and IT decreased significantly by day 3 in resolving bacterial keratitis. The rapid early phase reduction in IT and CT was followed by rapid late phase IT reduction. This study demonstrates that serial AS-OCT examination can be used to monitor in vivo the clinical course of inflammatory disease.
Aim To report on the complications associated with the use of intravitreal triamcinolone acetonide (IVTA) in a tertiary referral hospital setting. Materials and methods A retrospective case series review of all IVTA injections carried out over a period of 30 months. Results One hundred and thirty IVTA injections were performed; nine with limited local follow-up were excluded. Thus, 121 injections (108 patients, 114 eyes) were included in the study. Triamcinolone (4 mg) was used in all cases. Indications were diabetic macular oedema (n ¼ 41 eyes), retinal vein occlusions (n ¼ 27), postoperative cystoid macular oedema (n ¼ 24), exudative age-related macular degeneration (n ¼ 16), and others (n ¼ 6). No intraoperative complications were recorded. Postoperative intraocular pressure (IOP) readings of 22, 28, 35, and 40 mmHg or higher were recorded in 46.5, 29.8, 12.3, and 7.9% of eyes, respectively. IOP elevation was treated with antiglaucoma medication in all but one eye (0.9%) that required trabeculectomy and one (0.9%) that required vitrectomy with cataract extraction for suspected phacoanaphylactic glaucoma. Two eyes (1.8%) developed retinal detachment; both had previously been treated for retinal breaks. One eye (0.9%) developed culture-positive endophthalmitis. Conclusions Significant morbidity is associated with IVTA injection; clinicians should be aware when considering treatment options.
ObjectiveMicrobial keratitis is a sight-threatening complication of contact lens wear, which affects thousands of patients and causes a significant burden on healthcare services. This study aims to identify compliance with contact lens care recommendations and identify personal hygiene risk factors in patients who develop contact lens-related microbial keratitis.Methods and analysisA case–control study was conducted at the University Hospital Southampton Eye Casualty from October to December 2015. Two participant groups were recruited: cases were contact lens wearers presenting with microbial keratitis and controls were contact lens wearers without infection. Participants underwent face-to-face interviews to identify lens wear practices, including lens type, hours of wear, personal hygiene and sleeping and showering in lenses. Univariate and multivariate regression models were used to compare groups.Results37 cases and 41 controls were identified. Showering in contact lenses was identified as the greatest risk factor (OR, 3.1; 95% CI, 1.2 to 8.5; p=0.03), with showering daily in lenses compared with never, increasing the risk of microbial keratitis by over seven times (OR, 7.1; 95% CI, 2.1 to 24.6; p=0.002). Other risks included sleeping in lenses (OR, 3.1; 95% CI, 1.1 to 8.6; p=0.026), and being aged 25–39 (OR, 6.38; 95% CI, 1.56 to 26.10; p=0.010) and 40–54 (OR, 4.00; 95% CI 0.96 to 16.61; p=0.056).ConclusionThe greatest personal hygiene risk factor for contact lens-related microbial keratitis was showering while wearing lenses, with an OR of 3.1, which increased to 7.1 if patients showered daily in lenses. The OR for sleeping in lenses was 3.1, and the most at-risk age group was 25–54.
Purpose: Corneal perforations pose a considerable challenge for ophthalmic surgeons. The aim remains restoring the anatomical integrity of eye while attempting to preserve as much visual function as possible. To our knowledge, we report the first case series of 4 successful tectonic Descemet stripping endothelial keratoplasty (DSEK) grafts completed for acute corneal perforation. In all cases, restoration of globe integrity was achieved. In cases where visual potential remained, deep anterior lamellar keratoplasty over DSEK was offered. Methods: Four patients presenting to Royal Gwent Hospital (Newport, Wales) with corneal perforation were included. Etiological origins included exposure keratopathy, corneal hydrops secondary to pellucid marginal degeneration with fistulization-associated aqueous leak, and herpetic keratitis. Patients were treated with initial temporary therapies, including glue patch, the use of bandage contact lenses, amniotic membrane transplant, and antibiotic cover, depending on the size and location of the perforation. Subsequent DSEK was subsequently performed under local anesthesia. Results: All patients had successful tectonic grafts (3 DSEKs and 1 hemi-DSEK) up to 4 months postoperatively. In the case involving a hemi-DSEK, the patient underwent 2 refloating attempts of the graft before anchoring suture placement because of repeated graft detachment. Successful graft placement and tectonic globe restoration was confirmed by anterior segment imaging. Conclusions: Tectonic DSEK provides corneal surgeons with a new modality of treating corneal perforations. It provides clinicians an additional tool in their armamentarium in complex cases where anterior lamellar or penetrating keratoplasty may be contraindicated or deemed high risk of complications.
Poor visual outcome was associated with poor preoperative vision, age-related macular degeneration, cystoid macular edema, and secondary PPV following nuclear fragment loss. Primary PPV for nuclear fragment loss was not a significant association.
Aims To assess the efficacy and safety of intravitreal triamcinolone in the treatment of postoperative cystoid macular oedema (CMO). Methods A retrospective case series review of 21 eyes (20 patients) that had an intravitreal injection of triamcinolone 4 mg for postoperative CMO. Diagnosis was confirmed by fundus fluorescein angiography and/or optical coherence tomography in all eyes. Results Mean age of patients was 71.1 years. CMO had developed following routine phacoemulsification cataract extraction (13 eyes), phacoemulsification cataract extraction complicated by posterior capsule tear and vitreous loss (two eyes), vitrectomy (three eyes), or planned combined phacoemulsification and vitrectomy (three eyes). Mean duration of CMO before triamcinolone injection was 4.9 months. Mean duration of follow-up was 7.4 months. Two eyes required a repeat injection. Mean logarithm of minimum angle of resolution (LogMAR) visual acuity (VA) before treatment was 0.53; at 1 month post injection, this increased significantly to 0.33 (Po0.001). Improvement in VA was maintained throughout follow-up; at 6 months or later, mean LogMAR VA was significantly better than baseline (0.33 vs 0.53, P ¼ 0.02). At the latest review, 43% of eyes had improved Snellen VA by two or more lines and 86% by one or more lines compared to baseline. The remaining 14% had reduced Snellen VA compared to baseline. In the post-injection period, 33% of eyes developed an intraocular pressure of 22 mm Hg or higher and all responded well to short-term topical agents.There were no other post-injection complications. Conclusion Intravitreal triamcinolone results in a rapid improvement in VA that may be sustained for more than 6 months.
Most ophthalmologists are aware of the risk of elevated intraocular pressure developing 1 or 2 months after an intravitreal injection of triamcinolone. However, the two cases reported here demonstrate that such a rise can occur significantly later than this. All patients who have had intravitreal steroid injection should therefore have prolonged intraocular pressure monitoring.
