RESUMO

OBJECTIVE: To compare nonmydriatic spectral domain optical coherence tomography (NMOCT) to comprehensive ophthalmologic evaluation (COE) in detecting adult macular abnormalities. METHODS: This is a single-reader observational pilot study of adults older than 50 years with no known ophthalmologic problems to assess the correlation between NMOCT and COE in detecting macular abnormalities classified as epiretinal, intraretinal, subretinal, or a combination thereof. Subjects underwent NMOCT of the macula followed by COE which included a dilated fundus examination and ancillary tests as needed. RESULTS: A total of 771 eyes of 406 patients were included. Cohen's kappa coefficient of agreement between NMOCT and COE for detecting any abnormality was high (0.90, p < 0.0001), with NMOCT having an overall sensitivity of 82.65% and specificity of 98.97%. Sensitivities and specificities of NMOCT in detecting each category of macular abnormalities were as follows: epiretinal (86.36%, 99.73%), intraretinal (80.00%, 99.58%), and subretinal (88.89%, 99.73%), respectively. CONCLUSION: NMOCT is a promising tool for detecting adult macular abnormalities.

RESUMO

We have previously described a syndrome characterized by facial dysmorphism, lens dislocation, anterior-segment abnormalities, and spontaneous filtering blebs (FDLAB, or Traboulsi syndrome). In view of the consanguineous nature of the affected families and the likely autosomal-recessive inheritance pattern of this syndrome, we undertook autozygosity mapping and whole-exome sequencing to identify ASPH as the disease locus, in which we identified two homozygous mutations. ASPH encodes aspartyl/asparaginyl ß-hydroxylase (ASPH), which has been found to hydroxylate aspartic acid and asparagine residues on epidermal growth factor (EGF)-domain-containing proteins. The truncating and missense mutations we identified are predicted to severely impair the enzymatic function of ASPH, which suggests a possible link to other forms of ectopia lentis given that many of the genes implicated in this phenotype encode proteins that harbor EGF domains. Developmental analysis of Asph revealed an expression pattern consistent with the proposed link to the human syndrome. Indeed, Asph-knockout mice had a foreshortened snout, which corresponds to the facial abnormalities in individuals with Traboulsi syndrome. These data support a genetic basis for a syndromic form of ectopia lentis and the role of aspartyl hydroxylation in human development.

RESUMO

OBJECTIVE: To report the 15-year trend in ophthalmic presentations to the emergency department (ED) at the only medical center in Lebanon that provides 24-hour ophthalmologic care. METHODS: Retrospective review of 1967 patients presenting to the ED with eye-related complaints between September 1997 and August 1998 and between September 2012 and August 2013. Diagnoses were classified into 4 categories according to the International Society of Ocular Trauma and include penetrating eye injuries, nonpenetrating eye trauma, nontraumatic ophthalmic emergencies, and nontraumatic, nonurgent ophthalmic conditions. RESULTS: One thousand sixty eye-related presentations out of 39,158 total ED visits (2.71%) presented in 1997 compared to 907 out of 46,363 in 2012 (1.96%). Penetrating and nonpenetrating eye emergencies decreased between 1997 and 2012 (7.17% to 4.19%, p = 0.003 and 52.64% to 29.00%, p < 0.001, resp.) while nonurgent cases increased from 30.19% to 53.47% (p < 0.001). 57% of patients were covered by third-party guarantors in 1997 versus 73% in 2012. CONCLUSION: Our results demonstrate a significant increase in nonurgent cases in parallel with the proportion of third-party payers, an issue to be addressed by public health policies and proper resource allocation. A detailed nationwide review is needed to make solid recommendations for the management of ophthalmologic presentations in the ED.

RESUMO

OBJECTIVE: To estimate the 5-year incidence of progression rate and regression rate and risk factors for diabetic retinopathy (DR) in a cohort of Lebanese patients with type II diabetes. METHODS: We followed a cohort of 462 Lebanese patients with type II diabetes for over 5 years at the American University of Beirut Medical Center. Patients underwent yearly complete ophthalmic evaluation and fundus photographs and were assessed for the incidence, stage, and evolution of DR using modified Airlie House classification. RESULTS: Among the 462 patients, 281 had no DR at baseline. The 5-year cumulative incidence of any DR was 10% (95% CI: 6-13), and only baseline microalbuminuria correlated with the development of DR (OR = 10.53, 95% CI: 4.39-25.23, p < 0.0001). Among the 181 patients with baseline DR, the worsening and regression rates of DR were 31.5% (95% CI: 25-38) and 9% (95% CI: 5-13), respectively. Microalbuminuria also approached statistical significance as a risk factor for DR worsening (OR = 1.89, 95% CI: 0.97-3.70, p = 0.06). CONCLUSION: The 5-year incidence of DR in this hospital-based cohort is relatively low. Microalbuminuria was independently associated with the incidence and progression of the disease. We recommend to screen patients with type II diabetes for microalbuminuria as prognostic for the development and worsening of DR.

RESUMO

OBJECTIVE: To report a patient with Mycobacterium chelonae keratitis after LASIK and discuss therapeutic measures. DESIGN: Interventional case report and literature review. INTERVENTION: A healthy, 25-year-old man presented 6 weeks after LASIK with infectious keratitis in the left eye. Scrapings were obtained from the central stromal bed after lifting the flap and inoculated on culture media. MAIN OUTCOME MEASURES: Response to medical treatment. RESULTS: Mycobacterium chelonae was identified from stromal bed scrapings. The protracted course of the infection necessitated surgical debridement and flap amputation with slow and suboptimal response to prolonged (14 weeks) treatment with topical amikacin 3.3%, clarithromycin 1%, and levofloxacin 0.5%. The substitution of levofloxacin 0.5% with gatifloxacin 0.3% resulted in closure of the epithelial defect within 1 week and resolution of the infiltrates in 3 weeks. The combined regimen of gatifloxacin 0.3%, amikacin 3.3%, and clarithromycin 1% was continued for a total of 4 months. The patient remains infection free 1 year after stopping all antibiotics. CONCLUSION: Treatment of post-LASIK nontuberculous mycobacteria remains a challenge. Institution of combination therapy including fortified amikacin, clarithromycin 1%, and a fourth-generation fluoroquinolone appeared to be beneficial in this patient.

RESUMO

A 7-year-old boy had itching, foreign body sensation, and redness in his right eye. Unilateral cobblestone papillae and a shield ulcer were found. Topical antihistamines, mast cell stabilizers, and steroids led to marked improvement. Unilateral vernal keratoconjunctivitis should be included in the differential diagnosis of unilateral giant papillary conjunctivitis.

RESUMO

We present 2 cases of anterior chamber ointment with evidence of progressive endothelial cell loss. In both cases, an anterior segment optical coherence tomography (OCT) was similar to an OCT of a tobramycin-dexamethasone ointment placed on a pen tip. An anterior segment OCT also demonstrated the direct contact of the globule with the corneal endothelium. A gas chromatography/mass spectrometry analysis documented the similarity to tobramycin-dexamethasone ointment in 1 case. Anterior segment OCT can help in confirming the diagnosis. Corneal endothelial injury is a continuous process, and its clinical manifestation is related to the size of the globule, the initial endothelium count, and the duration of ointment contact, which is related to supine positioning. It is advisable to avoid ointments in the immediate postoperative period, especially in corneal wounds larger than 3 mm.

RESUMO

OBJECTIVE: To evaluate the efficacy of intravitreal triamcinolone acetonide in the management of persistent macular edema secondary to nonischemic central retinal vein occlusion (CRVO). METHODS: Twenty consecutive patients were selected with a 3- to 4-month history of nonischemic CRVO and persistent macular edema. These patients received a single intravitreal injection of 4 mg of triamcinolone acetonide (40 mg/mL). The follow-up period ranged from 10 to 12 months. The amount of macular edema was assessed by the amount of retinal thickening on clinical examination using the Goldmann contact lens and by the area and intensity of staining on fluorescein angiography. Treated patients were compared with a retrospectively matched group of patients who were managed with observation only. MAIN OUTCOME MEASURES: Changes in visual acuity and amount of macular edema were assessed in the treated patients and compared with the observation group. RESULTS: The mean baseline visual acuity in the treatment group was 20/132 vs 20/123 for the observation group (P =.57). After 1 week, the treated group had a mean visual acuity of 20/51. At final follow-up, the treated group had a mean visual acuity of 20/37 while the observation group had a mean visual acuity of 20/110 (P =.001). Sixty percent of treated patients had a final visual acuity of 20/40 or better vs only 20% in the observation group (P =.01). Forty percent of the untreated patients had a final visual acuity worse than 20/200 while none of the treated patients did (P<.001). At final follow-up, 75% of treated patients had complete resolution of macular edema on clinical examination vs only 20% of the untreated patients (P<.001). Two of the treated patients had recurrence of macular edema at 6 months, and 3 had elevated intraocular pressure. CONCLUSION: This study shows a treatment benefit from intravitreal triamcinolone in terms of visual acuity and macular edema for nonischemic CRVO.

RESUMO

PURPOSE: To examine the immediate effect of ocular rubbing on corneal topography. METHODS: Corneal topography and analysis were performed before, immediately after, and 5 minutes after eyelid rubbing in 29 volunteers without ocular disease. RESULTS: The surface regularity index increased from a baseline of 0.24 to 0.91 ( p< 0.0001) immediately after rubbing and returned to baseline after 5 minutes. The surface asymmetry index increased from 0.27 to 0.89 ( p= 0.0018) immediately after rubbing. There was a small amount of astigmatism induced immediately by rubbing (0.5 diopter) ( p= 0.01). CONCLUSIONS: Ocular rubbing should be avoided prior to standard corneal topography. The increased surface regularity index may reflect the alterations of the tear film and/or the molding of the corneal surface.

RESUMO

We present a report of a 28-year-old female with fungal keratitis due to Acremonium that was unresponsive to full medical therapy over 3 weeks. The patient was treated with superficial keratectomy, intrastromal and intracameral voriconazole injections. There was a marked clinical improvement beginning on day 3 post-therapy that was sustained until the last follow-up at 6 months. This is the first case of fungal keratitis due to Acremonium treated by a combination of intrastromal and intracameral voriconazole. This cost-effective treatment modality proved to be significant in impeding the progression of this potentially blinding disease and improving visual prognosis.

RESUMO

PURPOSE: To evaluate the role of intravitreal tissue plasminogen activator (tPA) in the management of central retinal vein occlusion (CRVO) in patients with symptoms for <3 days. METHODS: We evaluated the visual outcome of a consecutive series of patients with CRVO following intravitreal tPA injection. All patients presented with visual acuity worse than 20/50 within 3 days from the onset of symptoms. Main outcome measures included percentage of patients whose final vision improved to 20/50 or better and change in percentage of patients with vision of 20/200 or worse before and after treatment. RESULTS: Twelve patients received intravitreal tPA for CRVO. Nine patients (75%) had best-corrected visual acuity of 20/200 or worse at presentation compared with 4 patients (33%) at the last follow-up after treatment. Five (55%) of these 9 patients had final visual acuity that improved to 20/50 or better. The remaining four patients did not have improvement or their vision continued to worsen. All 4 patients had fluorescein angiographic evidence of >10 disk areas of capillary nonperfusion at presentation. Overall, 8 (67%) of 12 patients had final visual acuity of 20/50 or better. No side effects related to tPA injection were observed. CONCLUSION: Our data suggest that intravitreal tPA injection may have a beneficial role in the management of CRVO when used within a few days of the onset of symptoms in patients with no angiographic evidence of severe capillary nonperfusion even if initial visual acuity is 20/200 or worse.
