RESUMEN

PURPOSE: To report a case of presumed intraretinal tuberculosis evaluated with optical coherence tomography angiography. METHODS: Case report. RESULTS: A 61-year-old woman recently immigrated from China presented with round yellow-white retinal lesions in the left eye. The lesions were evaluated with multimodal imaging, including optical coherence tomography angiography. Subsequent serologic testing revealed a positive QuantiFERON-TB Gold test, whereas workup for other entities was negative. The patient was diagnosed with presumed intraretinal tuberculosis. She was started on systemic antitubercular therapy and the lesions regressed. The regression was documented with optical coherence tomography angiography. CONCLUSION: Case reports of primary intraretinal tuberculosis are uncommon. To the best of our knowledge, this is the first case to demonstrate optical coherence tomography angiography findings of presumed intraretinal tuberculosis.

RESUMEN

PURPOSE: To assess the impact of submacular fluid (SMF) after pneumatic retinopexy for primary rhegmatogenous retinal detachment repair. METHODS: Retrospective review of consecutive patients treated with pneumatic retinopexy for primary rhegmatogenous retinal detachment repair. 387 eyes (374 patients) were included, of which 166 underwent optical coherence tomography imaging after successful pneumatic retinopexy. Foveal-centered optical coherence tomography scans were reviewed. RESULTS: SMF occurred in 59 eyes (35.5%) and was associated with macular detachment ( P ≤ 0.001) and phakic lens status ( P = 0.007). Submacular fluid resolved over an average of 9.39 months and was associated with worse preprocedure best-corrected visual acuity and delayed visual recovery. The mean final best-corrected visual acuity was 0.277 logarithm of the minimum angle of resolution (20/40) in eyes with SMF and 0.162 logarithm of the minimum angle of resolution (20/30) in those without SMF ( P < 0.001). Submacular fluid was associated with discontinuity of the interdigitation zone ( P = 0.003), ellipsoid zone ( P = 0.005), and external limiting membrane ( P ≤ 0.001) after SMF resolution. Ellipsoid zone discontinuity was associated with worse visual prognosis ( P = 0.009). CONCLUSION: Trace SMF detected by optical coherence tomography is common after successful pneumatic retinopexy and resulted in delayed visual recovery and increased rates of outer retinal discontinuity after SMF resorption, although the final difference in best-corrected visual acuity in those with and without SMF was minimal.

RESUMEN

PURPOSE: To report a sporadic case of a familial adenomatous polyposis (FAP) discovered in a patient with bilateral retinal pigment epithelial lesions. METHODS: Case report. RESULTS: A 30-year-old Asian woman presented for evaluation of bilateral pigmented lesions at the level of the retinal pigment epithelium. She had no personal or family history of colonic polyps or colon cancer. Colonoscopy revealed innumerable adenomatous polyps and genetic testing revealed a mutation in the adenomatous polyposis coli gene consistent with FAP. She subsequently underwent prophylactic total colectomy. CONCLUSION: The pigmented retinal pigment epithelium lesions of FAP have a characteristic appearance and it is vital for the retinal specialist to be familiar with them. De novo mutations in the APC gene are responsible for 20% to 30% of FAP cases. In the presence of the characteristic retinal pigment epithelium lesions, it is important to send the patient for work up of FAP even in the absence of family history of FAP.

RESUMEN

PURPOSE: To discuss the mechanism of injury and characterize the clinical features of ocular trauma associated with elastic cord exercise equipment band injuries in a consecutive series of patients seen at a single vitreoretinal surgery practice. METHODS: We performed a retrospective review of all patients who were treated for blunt trauma from 2013 to 2020 at a single vitreoretinal practice. RESULTS: Thirteen eyes from 11 patients met the inclusion criteria of possessing ocular trauma secondary to recoil from exercise bands. Presenting visual acuity ranged from 20/16 to HM (median: 20/32). The most frequently observed anterior segment pathologies were traumatic iritis (54%) and angle recession (31%). The most common posterior segment findings were vitreous hemorrhage (54%) and peripheral commotio retinae (54%). Three eyes (23%) required surgical intervention. Follow-up intervals ranged from 0 to 10 months (median: 1.75 months). Visual acuity at last examination ranged from 20/13 to 20/400 (median: 20/40). CONCLUSION: A wide spectrum of serious ocular injuries requiring medical and surgical intervention can result from this form of blunt ocular trauma. The frequency of this event would be decreased by the use of sports goggles and careful inspection of equipment for wear and over use.

RESUMEN

A 78-year-old woman underwent 25-gauge pars plana vitrectomy and scleral fixation for a dislocated intraocular lens in the left eye under general anesthesia. She developed massive hemorrhagic choroidal detachment 1 day later. A giant retinal tear detachment and proliferative vitreoretinopathy was noted at postoperative Week 7 and repaired with choroidal drainage, 240° peripheral retinectomy, perfluorocarbon liquid, endolaser, and silicone oil. Hypotony associated with the 25-gauge sclerotomies used for suture fixation was the suspected etiology for this complication. Use of 27-gauge instrumentation or application of fibrin glue to superior sclerotomies may help reduce the incidence of postoperative hypotony.

RESUMEN

PURPOSE: To report on a case of submacular choroiditis in a patient with common variable immunodeficiency (CVID). OBSERVATIONS: An 80-year-old man was referred with a diagnosis of a central retinal vein occlusion with CME and later developed intraocular inflammation. History was notable for recurrent bacterial infections and myelodysplastic syndrome known to be due to CVID. Ophthalmic examination and multimodal imaging revealed mild intraocular inflammation, retinal vasculitis, submacular choroiditis, and CME. Genetic testing identified a point mutation in TNFRSF13B, a pathogenic variant in the tumor necrosis factor gene known to be associated with CVID, but not with CVID-associated uveitis. CONCLUSIONS AND IMPORTANCE: The diagnosis of CVID should be considered in patients with uveitis and a history of recurrent bacterial infections. Genetic testing can support the diagnosis.

RESUMEN

BACKGROUND: To evaluate the efficacy and patient satisfaction of laser in situ keratomileusis (LASIK) monovision correction in presbyopic emmetropic patients. METHODS: A retrospective review of 294 patients who underwent LASIK for monovision was conducted. All patients had preoperative uncorrected distance visual acuity in each eye of 20/25 or better in both eyes and underwent primary LASIK treatment in one eye with a near target; 82 patients underwent surgery in the distant eye for hypermetropia. Patients completed a patient-reported-outcome questionnaire at their one-month postoperative visit. Analysis was performed on a per patient basis with a logistic regression model. RESULTS: Patients achieved a postoperative mean spherical equivalent of -0.05 diopters (D) in the distant eye and -1.92 D in the near eye. Prior to surgery, 64.7% (n=178) of patients reported they were satisfied or very satisfied with their vision; postoperatively, this increased to 85.4% (n=251). The greatest predictor of dissatisfaction after surgery was severe patient-reported visual phenomena (glare, halos, starbursts, ghosting) (odds ratio 1.18, P=0.001). CONCLUSIONS: LASIK monovision for presbyopic patients with low refractive error and good preoperative uncorrected distance visual acuity is both safe and effective with high patient satisfaction. Patients who were dissatisfied in the postoperative period tended to be those with postoperative visual symptoms.

RESUMEN

PURPOSE: Understanding the spectrum of pathogens in a given geographic region is important when deciding on empiric antibiotic therapy. In this study, we evaluate the spectrum of bacterial organisms cultured from corneal samples and their antibiotic sensitivities to guide initial treatment of keratitis. METHODS: We performed a retrospective case review of cultures from suspected infectious keratitis cases at the Francis I. Proctor Foundation, University of California, San Francisco, from 1996 through 2015. Logistic regression models were used to assess the risk of culturing methicillin-resistant Staphylococcus aureus (MRSA) from ulcers over time and the association between the year cultured and moxifloxacin resistance. RESULTS: A total of 522 of 2203 (23.7%) cultures grew bacterial organisms believed to be the etiology of infection, with available antibiotic sensitivity data. Of these, 338 (65.3%) grew gram-positive organisms with the most common being methicillin-sensitive Staphylococcus aureus (20.1%, N = 105). One hundred eighty (34.7%) grew gram-negative species with Pseudomonas aeruginosa as the most prevalent organism (10.9%, N = 57). There was 1.13 increased odds of culturing MRSA for each 1-year increase in the culture date (P = 0.01) and 1.26 increased odds of culturing an organism resistant to moxifloxacin with each 1-year increase in the culture date after controlling for the infectious organism (P < 0.001). CONCLUSIONS: Gram-positive organisms are the most commonly identified etiology of microbial keratitis in this series. Approximately 35% of cultured organisms had variable susceptibility to moxifloxacin, and resistance seems to be increasing over time. The risk of culturing MRSA increased over time.

RESUMEN

BACKGROUND: Restoration of orbital volume after internal orbital fractures can prevent enophthalmos. A variety of allografts are commonly used including titanium mesh with and without porous polyethylene coating. Some controversy exists over the use of uncoated titanium mesh in the orbit. Newer products contoured to the three dimensional orbital anatomy aim to improve reestablishment of the complex orbital shape though studies of outcomes with their use are limited. METHODS: A retrospective chart review was performed to evaluate surgical outcomes in all patients who underwent orbital fracture repair with DePuy/Synthes titanium MatrixMIDFACE prefabricated implants (PFTi) as compared with porous polyethylene/titanium hybrid implants (PPETi) including Stryker Medpor Titan, MTB, and BTB implants. Incidence of reoperation, diplopia, and movement restriction between PFTi and PPETi groups and the risk ratio of the above outcomes between implant types were compared. RESULTS: A total of 464 orbital implants were reviewed. Patients were divided by implant type with 195 patients receiving a PFTi implant and 269 patients receiving PPETi implant. (PFTi) and 269 had placement of a porous polyethylene/titanium hybrid implant. Despite statistically significant increased probability of utilization in more complex and delayed fractures, the PFTi implant showed no significant difference in complication profile or reoperation rate compared to the more commonly used PPETi. CONCLUSIONS: PFTi implants, designed to replicate the native orbital shape, have similar surgical outcomes and no difference in complication profile compared to standard porous polyethylene/titanium implants hybrid plates.

RESUMEN

PURPOSE: To evaluate the usage of preoperative digital anatomic implant evaluation in internal orbital fractures. METHODS: An IRB-approved review of cases of orbital fracture repair was conducted and cases where digital implant modeling was performed were selected for comprehensive review. The surgical time of these cases was also compared with surgeon and implant matched controls. RESULTS: A total of 25 patients and 26 orbits underwent preoperative virtual fitting and were reviewed. There were no complications or revision surgeries needed. Postoperative assessment demonstrated accuracy to the preoperative target with an average maximum deviation of 1.9 mm. CONCLUSIONS: Preoperative digital fracture assessment, implant manufacturer and size selection, and virtual cutting guide creation provides additional tools for orbital surgeons to achieve anatomic restoration without significant differences in operating time.

RESUMEN

PURPOSE: To compare the Retinomax K-plus3 handheld autorefractor to a retinscopically based refraction performed by a pediatric ophthalmologist. METHODS: The medical records of 311 children aged 5 months to 17 years who underwent cycloplegic refraction by both autorefractor and a pediatric ophthalmologist on the same day were retrospectively reviewed. Spherical equivalent, vector dioptric distance (VDD) values, and t tests were performed for each metric with an accompanying age-group comparison (<5 years, 5-7 years, 8-10 years, and ≥11 years). Bland-Altman plots were generated to evaluate the agreement between methods. RESULTS: Overall, the refraction provided by the Retinomax autorefractor was not significantly different in regard to cylinder power and axis. An age-group comparison showed statistically similar readings for all measures of refractive error in children 8-10 years of age. Statistically similar readings were obtained for cylinder power and axis except in children aged 5-7 years. The VDD was statistically different between the two methods for every age group. Bland-Altman plots suggested agreement between the two approaches for the entire cohort with respect to sphere, cylinder, axis, and spherical equivalent. CONCLUSIONS: In children <18 years of age, there was no clinical difference in the cycloplegic refraction determined by the Retinomax autorefractor when compared to retinoscopy by a pediatric ophthalmologist.

RESUMEN

PURPOSE: To report a case of intraretinal neovascularization in a patient with ischemic central venous occlusion. METHODS: Case report. RESULTS: An 18-year-old white man presented with painless decreased vision in the right eye. Slit-lamp and biomicroscopic examinations revealed 360° of neovascularization of the iris, venous tortuosity, severe retinal hemorrhages, cotton wool spots, and massive edema of the macula. CONCLUSION: This is the first report of observed intraretinal neovascularization after central vein occlusion. Treatment with photocoagulation and intravitreal bevacizumab injection promoted revascularization after 1 year.
