RESUMEN

PURPOSE: The purpose of this study was to assess the role of combined surgical treatment of therapeutic penetrating keratoplasty and pars plana vitrectomy in the anatomical and functional outcome of infectious keratitis endophthalmitis. METHODS: This study reviewed the medical records of 4 participating centers in the United States and Mexico. This study included patients with a clinical diagnosis of infectious keratitis endophthalmitis who had been treated with an early therapeutic penetrating keratoplasty and pars plana vitrectomy as the main treatment for endophthalmitis. From each medical record, the study retrieved demographic data, relevant medical and drug history, baseline clinical manifestation of endophthalmitis, best-corrected visual acuity, and the need for enucleation/evisceration for the control of the infection or any other reason through the follow-up. RESULTS: The study included 48 patients (50.15 ± 20.6 years). The mean follow-up time was 13 ± 0.5 months. The mean best-corrected visual acuity at baseline was 2.1 ± 0.25 logarithm of the minimum angle of resolution. At month 12 was 2.09 ± 0.61 logarithm of the minimum angle of resolution ( P = 0.9). The overall prevalence of enucleation/evisceration was 8.3% (95% confidence interval: 2.32%-19.98%). The prevalence of a vision of no-light perception was 20.8% (95% confidence interval: 2.32%-19.98%). CONCLUSIONS: Combined surgery for severe cases of infectious keratitis endophthalmitis eradicates the infection in most cases, while significantly improving the overall outcomes.

RESUMEN

PURPOSE: This report details a case of an unusual late dislocation of a laser in situ keratomileusis (LASIK) flap due to animal-related trauma 16 years after the initial surgery. OBSERVATIONS: A 59-year-old woman with history of LASIK surgery on both eyes 16 years prior, and uncomplicated cataract surgery on the left eye (oculus sinister; OS) 3 years prior, arrived at our institution with sudden painful visual loss 3 hours after receiving a scratch on OS from her dog. Corneal examination revealed a completely displaced nasally hinged LASIK flap folded irregularly over the hinge, with multiple creases over its entire thickness. The flap was intact but edematous and opaque, with detritus present both on the flap surface and stromal face. Treatment was initiated with topical moxifloxacin and oral clindamycin. The next morning, the flap was refloated, and debris was removed from both sides of the flap while irrigating with preservative-free moxifloxacin. The flap was repositioned and a bandage contact lens placed. Postoperative topical medication included moxifloxacin, prednisolone acetate, and sodium hyaluronate. At the final follow-up visit, the patient was asymptomatic, with a measured uncorrected distance visual acuity (UDVA) of 20/25 OS. CONCLUSION AND IMPORTANCE: This uncommon case highlights the longest reported interval-16 years- between initial surgery and traumatic LASIK flap displacement, caused by animal-related trauma. Patients experiencing LASIK surgery complications, including contaminated trauma many years after the original ablation, can still recover excellent visual acuity when managed appropriately and in a timely fashion.

RESUMEN

PURPOSE: This study describes presenting clinical features and surgical techniques associated with successful repair of pediatric rhegmatogenous retinal detachment (RRD). METHODS: This is a retrospective case series which involved 242 cases younger than 18 years with new-onset RRD with descriptive statistics for the full group. Further exclusion established 168 cases that underwent surgery with minimum 3-month follow-up. Comparison of features associated with successful outcomes was analyzed using Chi-squared tests, logistic regression and univariate generalized equation models. RESULTS: We measured proportion of patients with BCVA ≤ 1.0 logMAR and/or an increase in final BCVA of 0.3 logMAR with respect to baseline and complete reattachment at final visit; 104 eyes (62%) achieved total reattachment, and 91 eyes (54%) achieved visual success. Absence of macular involvement, subtotal RRD and older age group (13-18) were associated with both success measures. There were higher visual and anatomic success rates with primary scleral buckling (SB, 66% and 79%; OR 9.26 and 11.09) and combined SB plus pars plana vitrectomy (PPV, 54% and 58%; OR 5.67 and 3.94) compared with PPV alone (26% and 17%). CONCLUSION: A majority of patients achieved anatomical success with repair. Trauma and myopia were the most common etiologic associations, with myopic cases having better outcomes. Success was more likely in patients with subtotal RRD or uninvolved macula at presentation; previous intraocular surgery was a risk factor for failure. Younger patients had a higher likelihood of worse outcomes. Initial PPV showed a lower rate of success than either SB or combined SB/PPV.

RESUMEN

BACKGROUND: The objective of this publication is to report a case of an atypical partial central retinal artery occlusion (CRAO) with substantial visual recovery without treatment. CASE PRESENTATION: An 83-year-old woman without significant medical history with sudden unilateral visual loss presented with no known significant ophthalmological or medical history besides systemic arterial hypertension. Examination showed multiple cotton-wool spots in a peripapillary distribution, as well as a heterogenous pattern of grey translucency in the macula resulting in an indistinct cherry-red spot. Fluorescein angiography showed normal choroidal filling and an important delay of dye transit through the retinal circulation. Carotid Doppler echography showed a small endothelial atherosclerotic plaque without hemodynamic repercussion. A detailed history and further examination revealed no other systemic diseases except for moderate hypercholesterolemia. The patient was referred for management of her hypertension but otherwise did not undergo specific therapy for CRAO because of the delayed presentation. Four weeks after the initial visual loss, the patient showed resolution of the retinal findings and a surprising improvement to 20/50 visual acuity. CONCLUSION: This case highlights a rare subtype of central retinal artery occlusion. In this disease, partial occlusion reveals atypical signs including large cotton-wool spots as the predominant finding, making the initial diagnosis difficult. Visual recovery may be significant in partial CRAO, even without treatment.
