Descemet’S Stripping Endothelial Keratoplasty

With the growing popularity of lamellar keratoplasty for selective replacement of diseased corneal tissue, it is important to understand the risk of developing an infection after the procedure. Although lesser than that postpenetrating keratoplasty, the reports on post lamellar keratoplasty infectious keratitis are not negligible. Trends of acute infections arising within 2 months of surgery are a subject of interest. Most of these infections are reported post Descemet’s stripping endothelial keratoplasty with a preponderance of Candida species. A donor to host transmission of infection is not uncommon. Among the Candida cases, about 80% seem to occur due to a donor to host transmission. Infections presenting as or progressing to endophthalmitis lead to a poor visual outcome. Strict aseptic measures and protocols during corneal tissue harvesting, tissue processing, tissue storage and surgery are essential to prevent occurrence of these infections. After the infection has occurred, determining the aetiology and drug susceptibility through microbiological testing is vital. This helps to guide treatment protocols and hence determines final outcome of these cases. Most cases require some form of surgical management for resolution of infection, most often a graft removal and therapeutic keratoplasty. Secondary surgical interventions are performed to restore graft clarity and achieve a good final visual outcome.

Fungal keratitis (FK) is a serious ocular infection that often poses significant diagnostic and therapeutic dilemmas. This study aimed to examine the causes, clinical characteristics, outcomes, and prognostic factors of FK in the UK. All culture-positive and culture-negative presumed FK (with complete data) that presented to Queen’s Medical Centre, Nottingham, and Queen Victoria Hospital, East Grinstead, between 2011 and 2020 were included. A total of 117 patients (n=117 eyes) with FK were included in this study. The mean age was 59.0±19.6 years (range, 4-92 years) and 51.3% patients were female. Fifty-three fungal isolates were identified from 52 (44.4%) culture-positive cases, with Candida spp. (33, 62.3%), Fusarium spp. (9, 17.0%), and Aspergillus spp. (5, 9.4%) being the most common organisms. Ocular surface disease (60, 51.3%), prior corneal surgery (44, 37.6%), and systemic immunosuppression (42, 35.9%) were the three most common risk factors. Hospitalisation for intensive treatment was required for 95 (81.2%) patients, with a duration of 18.9±16.3 days. Sixty-six (56.4%) patients required additional surgical interventions for eradicating the infection. Emergency therapeutic/tectonic keratoplasty was performed in 29 (24.8%) cases, though 13 (44.8%) of them failed at final follow-up. The final corrected-distance-visual-acuity (CDVA) was 1.67±1.08 logMAR. Multivariable logistic regression analyses demonstrated increased age, large infiltrate size (>3mm), and poor presenting CDVA (<1.0 logMAR) as significant negative predictive factors for poor visual outcome (CDVA of <1.0 logMAR) and poor corneal healing (>60 days of healing time or occurrence of corneal perforation requiring emergency keratoplasty; all p<0.05). In conclusion, FK represents a difficult-to-treat ocular infection that often results in poor visual outcome, with a high need for surgical interventions. Innovative treatment strategies are urgently required to tackle this unmet need.

Background:Corneal melt is a rare inflammatory disease of the peripheral cornea; it may lead to perforation of the globe and visual failure. Corneal melt can be a manifestation of systemic vasculitis in patients with RA and other conditions, such as cancer. Without early and aggressive treatment it may be associated with a poor visual outcome and a high mortality. It has been reported in patients with stable RA.Objectives:A case report in a patient with long standing but well controlled Rheumatoid Arthritis (RA) and metastatic disease.Methods:A 75 year old male with a background of sero positive Rheumatoid Arthritis for more than 10 years presented to the Eye Casualty with a two week history of a painful left red eye. His other medical history was significant for Stage IIB poorly differentiated cancer of the left lower lobe. Left lower lobectomy with a patch of diaphragm resected. Intratumoural lymphovascular invasion noted. He completed Adjuvant Carboplatin/Vinorelbine chemotherapy September, 2017. He had DVT proximal left leg 22ndof September, 2017. Follow up CT in 2018 demonstrated a right renal upper pole lesion for which he was awaiting biopsy with?metastatic lung disease vs primary renal carcinoma. His RA was well controlled on Methotrexate 10mg weekly. He had been treated by the ophthalmology team for left marginal Keratitis for the prior 2 months with steroid eye drops without significant improvement. On presentation to ED, he described sharp eye pain, waking him from the sleep, associated with watery discharge and photophobia. Examination showed corneal melt in left eye involving 25% of inferior portion of the cornea and spastic entropion with injecting eye lashes. He had no active joints and there were no other signs of vasculitis. CRP was 4.1. He had a negative ANA and ANCA; viral swabs were negative. He was admitted under the medical team. Intravenous Methyl Prednisolone was started. The patient felt better after 5 days of Methyl Prednisolone. Left temporary tarsorrhaphy was done by Ophthalmology. Cyclophosphamide was initiated after discussion with Oncologist pending the result of the renal biopsy. Patient was discharged after 5 days of admission in the hospitalResults:The renal biopsy was positive for metastatic Squamous cell carcinoma of lung. Cyclophosphamide was withdrawn and he was started on Carboplatin/Gemcitabine. The corneal melt improved with complete resolution of his visual symptoms.Conclusion:In this case, although the history of RA was felt by the ophthalmology team to be the most likely association with the corneal melt, we would argue the oncological diagnoses were likely the driving force behind the presentation.References:[1]Sule A, Balakrishnan C, Gaitonde S, Mittal G, Pathan E, Gokhale NS, et al.

Purpose: To describe surgical management and establish visual outcomes of open globe injury (OGI) in pediatric patients requiring vitrectomy. Methods: Forty-eight eyes of 48 pediatric patients underwent vitrectomy for OGI with secondary vitreoretinal complications in the eye center of Jilin University were included. Characteristics of patients, details of ocular examination and operation, presenting and final visual acuity were recorded. Results: Presenting visual acuity less than 20/400 was found in 44 eyes (91.7%), which included no light perception (NLP) in four eyes. At last visit, there was no eyes with visual acuity of NLP, and 19 eyes (39.6%) had a vision recovery to 20/400 or better. Mechanisms of injury, intraocular contents prolapse, presence of hyphema, intraocular foreign body, vitreous hemorrhage, retinal detachment, and total time from injury to PPV > 2 weeks were significant predictors of visual prognosis. Logistic regression analysis showed that hyphema was a significant predictive factor for poor visual outcome. Conclusion: Visual acuity was improved in most of the patients with OGI in this study. Hyphema is an important presenting ocular sign in estimating the post-vitrectomy visual outcome for OGI in children. Proper timing of vitrectomy is suggested, and in this study patients may benefit more with early vitrectomy as less proliferative vitreoretinopathy (PVR) was found together with a better visual acuity.

Anterior Lamellar Keratoplasty

Purpose: To compare the visual outcome of femtosecond laser-assisted anterior keratoplasty (FSALK) and microkeratome-assisted anterior lamellar keratoplasty (MALK) in anterior corneal dystrophy.  Methods: retrospective comparative chart review of 7 eyes that underwent FSALK and 7 eyes that underwent MALK. The primary outcome was the visual outcome of both procedures. The secondary outcome was the recurrence of the corneal dystrophies.Results: Mean follow-up time was 30±14(7-51) months for the FSALK group and 127±28(80-127) months for the MALK group. In the FSALK group the preoperative best spectacle-corrected visual acuity (BSCVA) improved from 20/63 to 20/25 at 36 months. In the MALK group there was 1 eye with documented BSCVA over 36 months follow-up; it improved from 20/160 preoperatively to 20/32 at 36 months. Uncorrected visual acuity (UCVA) at 36 months improved from 20/100 preoperatively to 20/63 in the FSALK group and from 20/200 preoperatively to 20/63 in the MALK group. Five eyes with Reis-Bucklers showed a clinical recurrence at a mean of 142±13(125-152) months. Two eyes with granular dystrophy showed a clinical recurrence at 23 and 80 months of follow-up. One eye in the MALK group had epithelial ingrowth. One eye in the FSALK group with compromised ocular surface due to 2 previous penetrating keratoplasty, suffered bacterial keratitis that ended up with corneal scarring. Conclusion: Both procedures improve visual outcome for anterior corneal dystrophy. FSALK has theoretical advantages over MALK; however, larger prospective studies are needed to prove this.

Objective: To evaluate the anatomical and visual outcomes of small-gauge vitrectomy in patients with advance diabetic eye diseases (ADED) and the predictive factors for poor visual outcome. Materials and methods: A retrospective study was conducted from 2009 to 2014. Data at baseline, 6 months, and 12 months post-surgery were collected along with baseline demographic data, indications of surgery, systemic associations, visual and anatomical outcome, and postoperative complications. Poor visual outcomewas defined as visual acuity worse than 6/36. Results: A total of 158 eyes from 133 patients were recruited. Mean age was 54.01 ± 11.57 years and mean follow-up was 9.9 ± 3.7 months. Indications for vitrectomy were vitreous haemorrhage (VH, 77 eyes [48.7%]), tractional retinal detachment (TRD) with macular involvement (75 eyes [47.5%]), and other causes in 6 eyes (3.8%). There was visual improvement in 59.3% of patients, 23.6% worsened, and 17.1% stabilized at 12 months post-surgery. Patients with VH (75.4%) showed significant improvement compared to patients with TRD (48.3%). Successful anatomical outcomes were achieved in VH (98.2%) and TRD (96.7%). However, patients with TRD were found to have a 2.4-fold higher risk of having poor visual outcomes. Conclusion: Small-gauge vitrectomy for ADED resulted in excellent visual and anatomical outcomes. Eyes with TRD were at a higher risk of developing poor visual outcomes.

Introduction. Retinoblastoma (RB) is the most common eye tumor in children. There have been significant improvements in treatment options targeting killing the tumor while also conserving the eye and attempting to conserve functional vision. Retinal detachment (RD) is not an uncommon event and compromises the vision and sometimes RB treatment. Materials and Methods. Retrospective review of 62 patients over a period of 8 years between 2012 and 2019 with eyes treated for RB and having persistent RD that did not resolve after complete tumor regression. Results. Forty-two patients of these 62 cases developed RD (67%). The RD resolved in 35 patients (83% of RD), and 7 patients (16% of RD) developed a persistent RD. In all the persistent RD groups (7 patients/11 eyes), RB and RD were present simultaneously in the first ophthalmological assessment. Sex ratio was 2 females/5 males. The mean age of diagnosis was 11 months. All eyes had advanced RB stages. Eight eyes had local treatment with transpupillary laser, 6 eyes received IAC, and 3 patients received systemic chemotherapy. In 9 eyes, the RD had both exudative and tractional components. Only one eye had a pure tractional RD due to persistent fetal vasculature, and one eye had rhegmatogenous RD component with presence of a tear in addition to exudation. None of the eyes received RD surgical repair. Conclusion. Persistent RD occurs in eyes with advanced RB stages with complex RD with more than one component. The dilemma is performing a vitrectomy in eyes with cancer and poor visual outcome.

Childhood Cataract

BackgroundRecent reports have suggested a significant change in the causes of blindness in children in low-income countries cataract becoming the leading cause. We aimed to investigate the presentations and surgical outcomes in children with cataract operated at different ages in Tanzania.MethodsWe conducted a prospective study of 228 children aged ≤192 months at three tertiary centres, 177 with bilateral cataracts and prospectively followed them for 1-year postsurgery. We collected demographic, surgical, preoperative and postoperative clinical characteristics using the standard childhood cataract surgical assessment questionnaire. Families were encouraged to return for follow-up by phone with travel reimbursement where necessary.ResultsPreoperatively, 76% bilateral children were blind in the better eye. 86% of children were followed up at 1 year and 54% bilateral children achieved visual acuity of 0.48 logMAR or better in the better eye and 5% were blind. 33% of unilateral children achieved visual acuity of 0.48 logMAR or better and 17% were blind. Preoperative blindness (adjusted OR (AOR) 14.65; 95% CI 2.21 to 97.20), preoperative nystagmus/strabismus (AOR 9.22; 95% CI 2.66 to 31.97) and aphakia (AOR, 5.32; 95% CI 1.05 to 26.97) predicted poor visual outcome in bilateral cases. 9% of 342 refracted eyes had initial postoperative cylinder of 1.5 D or more, as did a similar proportion (11%) of 315 eyes refracted 1 year after surgery. Acute fibrinous uveitis occurred in 41 (12%) eyes.ConclusionThree-quarters of children were blind preoperatively whereas over half had good vision 1-year postoperatively. Preoperative blindness, nystagmus/strabismus and aphakia predicted poor visual outcome, suggesting that cataract density determines density of amblyopia.
