RESUMEN

Purpose: To examine the prevalence and predictors of patient awareness of their disease in adults with age-related macular degeneration (AMD). Methods: This study analyzed 5553 adults 40 years or older in the 2005-2008 National Health and Nutrition Examination Survey who underwent retinal imaging. AMD was determined based on retinal images. Patient awareness of their AMD was assessed by a self-reported AMD diagnosis. Multivariable logistic regression models were constructed to examine the association of patient awareness of their AMD with sociodemographic characteristics and specific AMD lesion types on retinal imaging. Results: AMD was identified in 425 of the adults surveyed (6.5%) (95% confidence interval [CI], 5.5%-7.5%), including 87.7% (95% CI, 82.9%-92.5%) with early AMD and 12.3% (95% CI, 7.5%-17.1%) with late AMD. Among adults with either type of AMD on retinal imaging, 17.5% (95% CI, 13.1%-22.0%) were aware of their disease, which included 11.6% (95% CI, 8.4%-14.9%) with early AMD and 59.2% (95% CI, 43.1%-75.3%) with late AMD (P < .0001). In the same group, those aged 60 years or older (odds ratio [OR], 33.46; 95% CI, 7.67-146.03) and with a best-corrected visual acuity of 20/40 or worse (OR, 4.63; 95% CI, 2.95-7.26) had higher awareness of their AMD diagnosis, whereas Hispanic (OR, 0.28; 95% CI, 0.09-0.88) vs White adults and those who did not speak English at home (OR, 0.05; 95% CI, 0.01-0.41) had lower awareness of their diagnosis. Conclusions: Fewer than 1 in 5 adults with AMD were aware of their personal diagnosis, including fewer than 3 in 5 adults with late AMD. Older adults and those with worse vision were more likely to know they have AMD, whereas Hispanic adults and those who did not speak English at home were less likely. Efforts to increase patients' awareness of their AMD may improve rates of follow-up and prevent vision loss.

RESUMEN

PURPOSE: This study was performed to characterize changes in contrast sensitivity (CS) that occur in patients with age-related macular degeneration (AMD) using a novel test, the motion diamond stimulus (MDS). METHODS: This was a cross-sectional study in which 20 subjects with unilateral exudative AMD (eAMD) and contralateral dry AMD received 3 assessments: the Pelli-Robson (PR) CS Chart, the MDS test, and a visual function questionnaire-25 (VFQ-25). CS results from the PR, and MDS tests were compared across 3 groups: eyes with eAMD vs dry AMD, eAMD vs control, dry AMD vs control. Healthy, undilated eyes from another study served as the control group. Significance was determined using ANOVA analysis for the MDS output parameters (α: overall contrast threshold, ß: adaptability of the visual system) and PR logCS. Patients were also administered the VFQ-25 to assess vision-related quality of life. RESULTS: The ANOVA of the MDS data demonstrated a significant difference in visual function according to the ß parameter of the 3 groups, but no significant difference in the α parameter. PR CS results for the 3 groups were significantly different, further supporting the MDS results. Post-hoc analysis showed a significant difference in ß and PR log CS between the eAMD and control eyes. CONCLUSION: The MDS test is valuable in discerning CS impairments in patients with AMD. It can provide further insight into the visual changes experienced by patients with AMD and has potential to quantify visual function changes that are not found on visual acuity testing alone.

RESUMEN

PURPOSE: To demonstrate a novel approach to scleral fixation of posterior chamber intraocular lenses and capsular tension rings and segments in deep-set eyes using the Finesse FlexLoop (Alcon Laboratories). METHODS: The technique described herein, based on previous approaches to scleral fixation of posterior chamber intraocular lenses, uniquely employs the FlexLoop to "lasso" Gore-Tex sutures that have already been threaded through the eyelets of a CZ70BD (Alcon Laboratories) IOL and externalize them. RESULTS: All patients who underwent surgery with this technique experienced visual improvement. The only complication was of mild hyphema in the patient who had a capsular tension segment placed, which resolved with medical therapy. CONCLUSION: The advantages of this procedure include a smaller diameter instrument (FlexLoop) as compared to the 25-gauge forceps typically employed, an easier to perform surgical maneuver that alleviates the need for both precise placement and constant tension to be exerted by the surgeon to grasp the sutures, as well as an instrument that can function when bent up to 45° to help accommodate deep-set eyes requiring this procedure.

RESUMEN

AIM: To investigate the prevalence of retinal pathology in patients with a history of exposure to pentosan polysulfate sodium (PPS). METHODS: Patients exposed to PPS and seen in the ophthalmology clinic at Northwestern University during 1/1/2002 to 1/1/2019 were identified from electronic health records (EHR) by an electronic data warehouse (EDW) search. Visual acuity (VA), reasons for clinic visit, ocular conditions, and duration of exposure to PPS were noted. Chart review was performed for fundus exam findings and ophthalmologic imaging, specifically fundus photography, fundus autofluorescence, and ocular coherence tomography (OCT) images. When OCT or fundus photography was available, studies were evaluated by two independent graders. RESULTS: A total of 131 patients who were exposed to PPS and seen at the Northwestern Ophthalmology clinic were identified in the EHR. Forty patients of 131 had imaging. Patients with imaging or fundus examination suspicious for PPS maculopathy were placed into the suspect group. Of the 40 patients that had imaging, 5 (12.5%) had features suspicious for PPS maculopathy. Of the remaining 91, 5 (5.4%) had macular pigmentary changes described on fundus exam. Among the 10 patients in the suspect group, the average duration of PPS use was 4.2 years (range 0.3-11.6 years, interquartile range 5.5 years) and the average cumulative dose was 380g (range 29-1092g, interquartile range 132g). CONCLUSION: A novel drug-induced maculopathy has been associated with PPS use with a distinct clinical constellation that can be accurately identified with multimodal imaging.

RESUMEN

Purpose: This study evaluated a novel tool known as the motion diamond stimulus (MDS), which utilizes contrast-generated illusory motion in dynamic test regions to determine contrast sensitivity (CS). Methods: Patients with treated unilateral retinal vein occlusions (RVOs) underwent three assessments: the MDS, the Pelli-Robson (PR), and the National Eye Institute's Visual Function Questionnaire (VFQ-25). The MDS assessment produced two data end points, α and ß. The α value represents the overall contrast threshold level and the ß value serves to quantify the adaptability of the visual contrast system. The CS parameters from the MDS and log CS PR output values were used to compare RVO eyes (n = 20) to control eyes (n = 20). Results: The study participants had a mean composite VFQ-25 score of 89.5 ± 10.4 on the VFQ-25. A significant difference was observed between the RVO eyes and the control eyes in PR log CS scores (P value = 0.0001) and in MDS α value (P value = 0.01). No difference in MDS ß value was found between the study groups (P value = 0.39). Conclusions: The results for the MDS assessment's α parameter corroborated the PR scores, suggesting contrast sensitivity threshold impairment in patients with RVO. No significant difference in ß value was observed, suggesting that adaptability of the visual system is maintained in treated RVO eyes. Translational Relevance: Currently, visual complaints cannot be entirely identified by Snellen visual acuity alone. The MDS offers potentially a more complete look at visual function, by including contrast sensitivity and may be able to quantify changes otherwise overlooked in retinal disease progression.

RESUMEN

PURPOSE: This study describes the long-term visual and anatomic outcomes of anti-vascular endothelial growth factor (VEGF) treatment using a treat and extend dosing regimen. METHODS: This cross-sectional cohort study consisted of 224 treatment-naïve eyes with neovascular age-related macular degeneration (NV-AMD) from 202 patients that were treated with anti-VEGF agents bevacizumab, ranibizumab, and aflibercept using a treat and extend (TAE) regimen by four physician investigators in a large urban referral center from 2008 to 2015. Subjects were evaluated for visual acuity, injection frequency, and optical coherence tomography (OCT). RESULTS: Over a seven-year follow-up period (mean 3.4 years), an average 20.2 ± 14.7 injections were administered with 8.4 injections in the first year and 5.5 injections by the seventh year of remaining eyes undergoing treatment. Visual acuity was 0.70 logMAR (20/100 Snellen) at the first visit and 0.67 logMAR (20/93 Snellen) at the final visit, with 74% of eyes maintaining or gaining more than 2 lines of vision. Long-term, 45.1% of eyes achieved 20/50 or better, while 27.1% were 20/200 or worse. Of the treated patients, 61.2% received monotherapy with no difference in visual acuity outcomes or number of injections between the agents used. OCT analysis showed decreased fluid from initial to final follow-up visit: 70.1-15.6% with sub-retinal fluid (SRF) and 47.3-18.8% with intra-retinal fluid (IRF) with no difference between the agents were used. CONCLUSION: This study demonstrates that most patients (74%) improve or maintain visual acuity long-term using a TAE model with a significant portion (45.1%) achieving 20/50 or better visual acuity with sustained treatment.

RESUMEN

Importance: Bilateral diffuse uveal melanocytic proliferation is a rare sign of several systemic malignant neoplasms. Observations: A patient presenting with uveal melanocytic proliferation underwent a detailed physical examination and extensive imaging. No systemic malignant neoplasm was found. Chorioretinal biopsy was performed, and its immunohistochemical results revealed the presence of primary vitreoretinal lymphoma. Conclusions and Relevance: This patient's results suggest that diffuse uveal melanocytic proliferation may be associated not just with systemic malignant disease, but also with primary intraocular tumors, in this case a primary vitreoretinal lymphoma.

RESUMEN

PURPOSE: To determine the prevalence of retinopathy among patients undergoing heart transplantation screening and to determine the impact of this finding on eligibility for transplantation. METHODS AND PATIENTS: A retrospective case series was collected to perform an institutional review of all inpatient consults for dilated eye examinations on potential heart transplant candidates over 5.5 years-from March 27, 2008 to October 10, 2014. Measured outcomes included the presence or absence of retinopathy and the effect of retinopathy, if present, on a patient's eligibility for cardiac transplantation. RESULTS: A total of 155 heart transplant candidates underwent bedside ophthalmologic examination as part of their heart transplant candidacy workup. Retinopathy was found in 16 (10%) of these patients: diabetic retinopathy in 13 (8.4%) and hypertensive retinopathy in 3 (1.9%). None of these patients were excluded from the transplant candidacy based on the presence of retinopathy. CONCLUSION: On bedside ophthalmologic examination, retinopathy is an uncommon finding among cardiac transplant candidates. Retinopathy did not preclude transplantation in these patients. We question the utility of the present system of bedside ophthalmic consultation of heart transplant candidates. This may not be an optimal allocation of provider resources. Further studies are warranted to determine an appropriate protocol for ocular evaluation of these patients.

RESUMEN

BACKGROUND AND OBJECTIVE: Submacular fluid (SMF) can persist for months to years following rhegmatogenous retinal detachment (RD) repair. The authors' objective was to describe fundus autofluorescence (FAF) and optical coherence tomography (OCT) findings associated with the absorption of persistent submacular fluid (SMF) following RD repair. PATIENTS AND METHODS: Retrospective review of clinical data and FAF and OCT imaging from sequential postoperative visits in a cohort of patients with persistent SMF following RD repair. RESULTS: In 11 of 13 eyes with persistent SMF, patches of decreased FAF signal corresponded to SMF on OCT. In eight eyes, there was a hypo- to hyperautofluorescence transition at the time of SMF resolution. These areas of increased FAF signal correlated with inner segment/outer segment (IS/OS) junction loss on OCT. CONCLUSION: FAF imaging can be informative when following SMF after RD repair; a hypo- to hyper-FAF signal transition correlates with SMF resolution and photoreceptor loss.

RESUMEN

BACKGROUND AND OBJECTIVE: To study the prevalence of peripheral retinal disease in patients with Marfan Syndrome (MFS). PATIENTS AND METHODS: In this observational, cross-sectional case series, patients with MFS were recruited by the Marfan Eye Consortium of Chicago during the National Marfan Foundation's annual conference. Patients underwent a fully dilated exam by vitreoretinal specialists in addition to ultra-widefield fundus photography using a scanning laser ophthalmoscope (Optos 200Tx; Optos PLC, Dunfermline, Scotland, United Kingdom). RESULTS: Clinical examination revealed posterior segment pathology in 18% of eyes with increased incidence to 70% in patients with a subluxed lens. In six out of 10 subjects in whom the clinical exam was suboptimal (young age, small pupil, and limited cooperation), the Optos provided a superior view of the peripheral retina compared to clinical exam alone. CONCLUSION: Clinical exam of MFS patients revealed similar posterior segment pathology as noted in previous literature, with improved detection of peripheral retinal disease with the use of ultra-widefield imaging.

RESUMEN

BACKGROUND AND OBJECTIVE: To quantitatively evaluate the change in pigment epithelial detachment (PED) morphology on spectral-domain optical coherence tomography (SD-OCT) 18 months after the transition to intravitreal aflibercept in patients with neovascular age-related macular degeneration (AMD) with PED recalcitrant to monthly intravitreal bevacizumab or ranibizumab. PATIENTS AND METHODS: Retrospective case series examining patients with neovascular AMD who had a persistent fibrovascular or serous PED on SD-OCT. PED volume was calculated by manually outlining the PED on individual OCT slices of the raster scan and multiplying by the pixel dimensions. RESULTS: Eleven eyes of 10 patients who had received an average of 25.7 ± 20.1 (range: 6 to 70) prior bevacizumab or ranibizumab injections over a period of 26.6 ± 19.8 months (range: 4 to 63) were included. PED volume decreased with aflibercept from 0.687 ± 0.837 mm(3) to 0.562 ± 0.705 mm(3) (P = .02), a decrease of 19% ± 12.27%. CONCLUSION: After 18 months of aflibercept, recalcitrant PED volumes were reduced by 19% while preserving visual acuity in eyes with neovascular AMD.

RESUMEN

PURPOSE: To describe the long-term outcomes of patients with cytomegalovirus (CMV) retinitis and AIDS in the modern era of combination antiretroviral therapy. DESIGN: Prospective, observational cohort study. PARTICIPANTS: Patients with AIDS and CMV retinitis. METHODS: Immune recovery, defined as a CD4+ T-cell count >100 cells/µl for ≥3 months. MAIN OUTCOME MEASURES: Mortality, visual impairment (visual acuity <20/40), and blindness (visual acuity ≤20/200) on logarithmic visual acuity charts and loss of visual field on quantitative Goldmann perimetry. RESULTS: Patients without immune recovery had a mortality of 44.4/100 person-years (PYs) and a median survival of 13.5 months after the diagnosis of CMV retinitis, whereas those with immune recovery had a mortality of 2.7/100 PYs (P < 0.001) and an estimated median survival of 27.0 years after the diagnosis of CMV retinitis. The rates of bilateral visual impairment and blindness were 0.9 and 0.4/100 PYs, respectively, and were similar between those with and without immune recovery. Among those with immune recovery, the rate of visual field loss was approximately 1% of the normal field per year, whereas among those without immune recovery it was approximately 7% of the normal field per year. CONCLUSIONS: Among persons with CMV retinitis and AIDS, if there is immune recovery, long-term survival is likely, whereas if there is no immune recovery, the mortality rate is substantial. Although higher than the rates in the population not infected by human immunodeficiency virus, the rates of bilateral visual impairment and blindness are low, especially when compared with rates in the era before modern antiretroviral therapy.

RESUMEN

PURPOSE: To evaluate the risk of cataract in the setting of AIDS. DESIGN: Prospective cohort study. PARTICIPANTS: Subjects with AIDS free of ocular opportunistic infections throughout catamnesis. METHODS: From 1998 through 2008, subjects 13 years of age or older were enrolled. Demographic characteristics and clinical characteristics were documented at enrollment and semiannually. MAIN OUTCOME MEASURES: Cataract was defined as high-grade lens opacity observed by biomicroscopy judged to be the cause of a best-corrected visual acuity worse than 20/40. Eyes that underwent cataract surgery during follow-up were considered to have developed cataract before the first visit when pseudophakia or aphakia was observed. RESULTS: Among 1606 participants (3212 eyes) at enrollment, 1.9% (95% confidence interval [CI]: 1.3%-2.7%) were observed to have cataract or prior cataract surgery. Among the 2812 eyes initially free of cataract and followed longitudinally (median follow-up, 4.6 years), the incidence of cataract was 0.37%/eye-year (95% CI: 0.26%-0.53%). In addition to age, significant cataract risk factors included prior cataract in the contralateral eye (adjusted hazard ratio [aHR], 21.6; 95% CI: 10.4-44.8), anterior segment inflammation (aHR, 4.40; 95% CI: 1.64-11.9), prior retinal detachment (aHR, 4.94; 95% CI: 2.21-11.0), and vitreous inflammation (aHR, 7.12; 95% CI: 2.02-25.0), each studied as a time-updated characteristic. Detectable human immunodeficiency virus RNA in peripheral blood was associated with lower risk of cataract at enrollment (adjusted odds ratio, 0.32; 95% CI: 0.12-0.80) but not of incident cataract (aHR, 1.58; 95% CI: 0.90-2.76). After adjustment for other factors, neither the then-current absolute CD4+ T-cell count nor antiretroviral therapy status showed consistent association with cataract risk, nor did an additive diagnosis of other comorbidities. Compared with the available population-based studies that used similar definitions of cataract, the age-specific prevalence of cataract in our cohort was higher than in 1 of 2 such studies, and the age-specific incidence of cataract surgery was higher. CONCLUSIONS: Our results suggest cataract may occur earlier among patients with AIDS free of ocular opportunistic infections than in the general population. Cataract risk was associated most strongly with age and with other ocular morbidity in this population. With improved survival, the burden of cataract likely will increase for persons with the human immunodeficiency virus or AIDS.

RESUMEN

PURPOSE: To evaluate the imaging characteristics of macular neovascular pigment epithelial detachments (PEDs) and their response to anti-vascular endothelial growth factor (VEGF) therapy. METHODS: Patients with exudative age-related macular degeneration (AMD), idiopathic polypoidal choroidal vasculopathy, presumed ocular histoplasmosis syndrome (POHS) and central serous retinopathy (CSR) with choroidal neovascularisation (CNV) were included in the study. A retrospective chart review of 72 eyes of 64 patients was performed. RESULTS: Three types of PEDs were identified based on reflectivity of the material under the retinal pigment epithelium on optical coherence tomography: hollow (26 eyes with primarily hyporeflectivity under the PED), solid (30 eyes with primarily hyperreflective signal under the PED) and mixed (8 eyes with mixed reflectivity). The average number of anti-VEGF injections was 7 per eye and the average duration of follow-up was 16 months. Among eyes with exudative AMD, 7/21 hollow PEDs flattened, 1/19 solid PEDs flattened and 2/6 mixed PEDs flattened after anti-VEGF therapy. POHS and CSR with CNV were associated with subfoveal solid PEDs and were unchanged after therapy. Overall, 46% (12/26) with hollow PEDs, 25% (2/8) with mixed PEDs and 3% (1/30) with solid PEDs had flattening after anti-VEGF therapy. CONCLUSIONS: The likelihood of PED flattening was inversely related to the reflectivity of the PED. The more reflective the PED, the less likely resolution with anti-VEGF therapy occurred.

RESUMEN

PURPOSE: To report the incidence and clinical outcomes of non-cytomegalovirus (non-CMV) ocular opportunistic infections in patients with acquired immunodeficiency syndrome (AIDS) in the era of highly active antiretroviral therapy. DESIGN: Multicenter, prospective, observational study of patients with AIDS. METHODS: Medical history, ophthalmologic examination, and laboratory tests were performed at enrollment and every 6 months subsequently. Once an ocular opportunistic infection was diagnosed, patients were seen every 3 months for outcomes. RESULTS: At enrollment, 37 non-CMV ocular opportunistic infections were diagnosed: 16 patients, herpetic retinitis; 11 patients, toxoplasmic retinitis; and 10 patients, choroiditis. During the follow-up period, the estimated incidences (and 95% confidence intervals [CI]) of these were: herpetic retinitis, 0.007/100 person-years (PY) (95% CI 0.0004, 0.039); toxoplasmic retinitis, 0.007/100 PY (95% CI 0.004, 0.039); and choroiditis, 0.014/ 100 PY (95% CI 0.0025, 0.050). The mortality rates appeared higher among those patients with newly diagnosed or incident herpetic retinitis and choroiditis (rates = 21.7 deaths/100 PY [P = .02] and 12.8 deaths/100 PY [P = .04]), respectively, than those for patients with AIDS without an ocular opportunistic infection (4.1 deaths/100 PY); toxoplasmic retinitis did not appear to be associated with greater mortality (6.4/100 PY, P = .47). Eyes with newly diagnosed herpetic retinitis appeared to have a poor visual prognosis, with high rates of visual impairment (37.9/100 PY) and blindness (17.5/100 PY), whereas those outcomes in eyes with choroiditis appeared to be lower (2.3/100 PY and 0/100 PY, respectively). CONCLUSIONS: Although uncommon, non-CMV ocular opportunistic infections may be associated with high rates of visual loss and/or mortality.

RESUMEN

OBJECTIVE: To evaluate cataract risk in eyes of patients with AIDS and cytomegalovirus (CMV) retinitis and to identify risk factors. DESIGN: Prospective cohort study. PARTICIPANTS: Patients with AIDS and CMV retinitis. METHODS: Patients 13 years of age and older were enrolled between 1998 and 2008. Demographic and clinical characteristics, slit-lamp biomicroscopy findings, and dilated ophthalmoscopy results were documented at quarterly visits. Cataract status was determined at the initial visit (prevalence) and at follow-up visits (incidence). MAIN OUTCOME MEASURES: For cataract, a high grade of lens opacity by biomicroscopy to which best-corrected visual acuity worse than 20/40 was attributed. Eyes that had undergone cataract surgery before enrollment or between visits also were counted as having cataract. RESULTS: Seven hundred twenty-nine eyes of 489 patients diagnosed with CMV retinitis were evaluated. Higher prevalence was observed for patients with bilateral versus unilateral CMV retinitis (adjusted odds ratio [aOR], 2.74; 95% confidence interval [CI], 1.76-4.26) and, among unilateral CMV retinitis cases, for eyes with retinitis versus without retinitis (15% vs. 1.4%; P<0.0001). The age-adjusted prevalence of cataract among CMV retinitis cases was higher than that in a population-based sample (P<0.0001). Cataract prevalence increased with age (aOR, 11.77; 95% CI, 2.28-60.65 for age ≥ 60 years vs. younger than 40 years) and longer duration of retinitis (aOR, 1.36; 95% CI, 1.20-1.54 per year). Among eyes with CMV retinitis initially free of cataract, the cataract incidence was 8.1%/eye-year (95% CI, 6.7%-10.0%). Prior retinal detachment was associated with higher cataract risk (if repaired with silicone oil: adjusted hazard ratio [aHR], 10.37; 95% CI, 6.51-16.52; otherwise: aHR, 2.90; 95% CI, 1.73-4.87). Large CMV retinitis lesions also were associated with higher risk of cataract (for involvement of 25-49% retinal area: aHR, 2.30; 95% CI, 1.51-3.50; for ≥ 50% involvement: aHR, 3.63; 95% CI, 2.18-6.04), each with respect to ≤ 24% involvement, as were anterior segment inflammation (aHR, 2.27; 95% CI, 1.59-3.25) and contralateral cataract (aHR, 2.52; 95% CI, 1.74-3.66). CONCLUSIONS: Cytomegalovirus retinitis is associated with a high absolute and relative risk of cataract. Among several risk factors, large retinal lesion size and use of silicone oil in retinal detachment repair are potentially modifiable, albeit not in all cases. Cataract is likely to be an increasingly important cause of visual morbidity in this population.

RESUMEN

PURPOSE: To investigate the relationship between contrast sensitivity (CS) and mortality among people with acquired immunodeficiency syndrome (AIDS); and to explore the hypothesis that abnormal CS is a marker of systemic, life-threatening microvascular disease. DESIGN: Longitudinal, observational cohort study. METHODS: We evaluated 3395 eyes of 1706 individuals enrolled in the Longitudinal Study of the Complications of AIDS (1998-2008). CS was evaluated as a risk factor for death, and was compared to the presence of systemic diseases characterized by microvasculopathy (diabetes, cardiovascular disease, stroke, renal disease) and to laboratory markers of those diseases. Abnormal CS was defined as logCS <1.5 (lower 2.5th percentile for a normal control population). RESULTS: CS was abnormal in 284 of 1691 (16.8%) study participants at enrollment. There was a positive relationship between the presence of abnormal CS at study entry and mortality (relative risk 2.0, 95% confidence interval 1.7-2.3, P < .0001). Abnormal CS was related to the presence of cardiovascular disease, stroke, and renal disease (all P values

RESUMEN

PURPOSE: To report the clinical findings and management of a case of fungal keratitis with extension into the anterior chamber following penetrating keratoplasty. METHODS: Interventional case report. RESULTS: A 45-year-old man developed a white, cottonball-like mass in the anterior chamber 3 months after penetrating keraplasty for keratoconus. Cytology evaluation was performed following excisional biopsy of the intracameral portion of the lesion. The presence of filamentous fungus was confirmed. The patient was treated with oral, topical, and intracameral voriconazole with complete resolution of the infection 9 months after initial presentation. CONCLUSION: This case illustrates the unusual presentation of fungal keratitis with intracameral extension and demonstrates effective management with preservation of the corneal graft and restoration of visual function.

RESUMEN

PURPOSE: To report the use of photodynamic therapy with verteporfin as a treatment for patients with focal retinal pigment epithelial leaks secondary to central serous chorioretinopathy (CSC). DESIGN: Noncomparative, nonrandomized, retrospective interventional case series. PARTICIPANTS: Nine eyes of 9 symptomatic patients with acute focal retinal pigment epithelial leaks secondary to CSC, confirmed with fluorescein angiography, evaluated at 1 of 3 referral retina practices. METHODS: Patients were treated with photodynamic therapy using verteporfin. Best-corrected visual acuity (VA) was recorded at presentation and follow-up visits. MAIN OUTCOME MEASURES: Resolution of neurosensory detachment, status of fluorescein leakage, and VA. RESULTS: Neurosensory detachment and fluorescein leakage resolved in all patients within 1 month. Visual acuity improved from 1 to 6 lines in 7 eyes and remained unchanged in 2. At 6 months, there was a statistically significant improvement in mean VA (P = 0.012, Wilcoxon signed ranks test), and mean VA improved from 20/80 to 20/40. No patient lost vision or suffered any treatment-related complications. CONCLUSION: The treatment of acute CSC with photodynamic therapy may result in prompt resolution of neurosensory detachment and fluorescein leakage, which can be associated with rapidly improved vision. Although this case series is limited in follow-up and number of patients, the encouraging results and lack of visually significant complications suggest that further investigation is warranted.
