Epilens membrane simulating cataract in children with uveitis: a report of three cases

ABSTRACTHere we present the cases of three female children, of whom two were aged 6 years and one was aged 11 years. Two of the three children had bilateral uveitis and suspected cataract and Vogt-Koyanagi-Harada (VKH) disease. The third one had uveitis and suspected cataract in one eye and sympathetic ophthalmia (SO), and had undergone penetrating keratoplasty in the fellow eye following a trauma. After controlling the inflammation, we planned to perform phacoemulsification without intraocular lens implantation. However, intraoperatively, after removing the epilens membranes, the lenses appeared clear, and therefore phacoemulsification was not performed. During follow-up, the patients did not develop cataract, and visual acuity levels ranged from 20/30 to 20/100. Fundoscopy revealed VKH disease and SO. Ophthalmologists should not always assume that patients with uveitis have cataract; a transparent lens may exist behind the epilens membrane, allowing a less aggressive therapeutic approach

Tacrolimus eye drops as monotherapy for vernal keratoconjunctivitis: a randomized controlled trial

Purpose: To assess the efficacy of monotherapy using tacrolimus eye drops versus sodium cromoglycate for the treatment of vernal keratoconjunctivitis (VKC). Methods: Randomized double-masked controlled trial comparing the efficacy of tacrolimus 0.03% eye drops t.i.d. (Group 1) with sodium cromoglycate 4% eye drops t.i.d. (Group 2) for the symptomatic control of VKC at days 0, 15, 30, 45, and 90 of follow-up. Visual acuity, intraocular pressure, and other complications were evaluated to assess safety and side effects. Results: In total, 16 patients were included, with 8 enrolled in each group. Two patients from Group 2 were excluded from the analysis at days 45 and 90 because of corticosteroid use. Most patients were male (81.8%) and presented with limbal VKC (56.3%). There were statistically significant differences in favor of tacrolimus in the following severity scores: itching at day 90 (p = 0.001)foreign body sensation at day 15 (p = 0.042)photophobia at day 30 (p = 0.041)keratitis at day 30 (p = 0.048)and limbal activity at days 15 (p = 0.011), 30 (p = 0.007), and 45 (p = 0.015). No relevant adverse effects were reported, except for a burning sensation with tacrolimus, though this did not compromise treatment compliance. Conclusion: Treatment with tacrolimus was superior to sodium cromoglycate when comparing severity scores for symptoms of itching, foreign body sensation, and photophobia, as well as for signs of limbal inflammatory activity and keratitis.Instituto da Visao (IPEPO), Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Ophthalmol & Visual Sci, Sao Paulo, BrazilUniv Fed Sao Paulo, Dept Ophthalmol & Visual Sci, Sao Paulo, BrazilWeb of Scienc

Multimodal imaging analyses of hyperreflective dot-like lesions in acute syphilitic posterior placoid chorioretinopathy

Background: Retrospective review of one acute syphilitic posterior placoid chorioretinitis (ASPPC) case with serological evidence of syphilis who had ocular signs and symptoms not attributable to other diseases. Enface and spectral-domain optical coherence tomographySD-OCT were analyzed at the time of presentation and at 1-month visit following initiation of treatment. The study patient underwent standard treatment for neurosyphilis. Results: Ophthalmic examination and imaging studies were consistent with the diagnosis of ASPPC. The patient age was 33 year-old and the baseline visual acuity was 20/400 and 20/80 in the right and left eyes, respectively. At presentation, SD-OCT scans showed disruption and loss of the ellipsoid zone (EZ), small nodular elevations on retinal pigment epithelium (RPE) and punctate hyperreflectivity in the choroid. Enface OCT at the level of RPE and EZ demonstrated multiple hyperreflective dot-like lesions simmetrically distributed within the macular area. These dot-like lesions corresponded to the small nodular elevations on RPE and to disruption/loss of EZ observed with SD-OCT. One month after neurosyphilis therapy, the visual acuity improved and the outer retinal changes partially reversed in both eyes. Conclusions: We report the outer retinal findings and its correlation using both en-face and SD-OCT in a patient with ASPPC. En-face OCT imaging provides a more precise outer retinal layers analyses allowing a better understanding of the ASPPC pathophysiology.Univ Fed Sao Paulo, Dept Ophthalmol, Sao Paulo, BrazilFed Univ Sao Paulo UNIFESP, Rua Botucatu,821,Vila Clementino, BR-04023062 Sao Paulo, SP, BrazilUniv Fed Sao Paulo, Dept Ophthalmol, Sao Paulo, BrazilFed Univ Sao Paulo UNIFESP, Rua Botucatu,821,Vila Clementino, BR-04023062 Sao Paulo, SP, BrazilWeb of Scienc

Teleophthalmology Support for Primary Care Diagnosis and Management

This study was performed to evaluate a healthcare strategy based on teleophthalmology for diagnosis and management of primary healthcare users. A descriptive cross-sectional study was conducted to review the medical records of patients from January 2013 to December 2014 from primary care units in the city of São Paulo. The units referred patients, who had diabetes or high blood pressure, and were users of chloroquine compounds, for a fundus examination. The images were sent to a reading center for review, diagnosis, and patient referrals. From 9173 analyzed patients, 570 (6.2%) were excluded because of poor image quality. Of the remaining patients, 4933 (57.3%) had diabetes, 7242 (84,2%) systemic hypertension, and 113 (1.3%) used chloroquine. Of these, 989 (11.5%) patients needed ophthalmologic treatment. The most frequently prescribed treatments were cataract extraction in 692 (70%) of 989 and photocoagulation in 245 (24.8%) of 989 cases. Overall, cataract extraction was indicated in 692 (8%) of 8603 cases and photocoagulation in 245 (2.8%) of 8603 cases. When only patients with diabetes were considered, the indication for photocoagulation increased to 4.5%.The results showed that non-medical professionals could produce good-quality ocular images for screening of ocular diseases in most cases; only 6.2% of ocular images did not meet quality requirements. Most patients referred for fundus examination did not need a specific treatment, indicating that this system could be an inexpensive and reliable tool for use in developing countries.Â

Herpes zoster ophthalmicus and varicella zoster virus vasculopathy

Herpes zoster (HZ) corresponds to the reactivation of varicella zoster virus (VZV). Among adults, the ophthalmic division of the trigeminal nerve is one of the most common sites of involvement. Vasculopathy caused by HZ is associated with significant morbidity and mortality, affecting structures such as the brain, which can lead to stroke. In this review, we analyzed the epidemiological and clinical aspects of the vascular involvement of VZV, focusing on the peculiarities of its association with ocular HZ. A review of the available literature indicated that ocular involvement of HZ was a risk factor for vasculopathy after adjusting for age, sex, body mass index, smoking, indicators of metabolic syndrome, and vascular and heart diseases. Considering the severity of this complication, vascular disease mediated by VZV requires early diagnosis and aggressive treatment. Finally, the anti-HZ vaccine has been recommended as a prophylactic measure in the elderly, but it should be used with caution in immunocompromised individuals.Univ Fed Sao Paulo UNIFESP, EPM, Dept Ophthalmol & Visual Sci, Sao Paulo, SP, BrazilSoc Brasileira Imunizacao, Sao Paulo, SP, BrazilInst Visao, Sao Paulo, SP, BrazilUniv Fed Sao Paulo UNIFESP, EPM, Dept Ophthalmol & Visual Sci, Sao Paulo, SP, BrazilWeb of Scienc
