RESUMO

PURPOSE: To analyze higher-order aberrations (HOAs) and their visual impact in a pediatric blepharokeratoconjunctivitis (PBKC) cohort compared with healthy controls. METHODS: Prospective case-control study of pediatric patients (≤ 16 years old). Subjects underwent wavefront aberrometry analysis to compare HOAs and their impact on visual quality. RESULTS: A total of 150 eyes from 76 patients were included in the analysis. The PBKC group consisted of 50 eyes and the control group of 100 healthy eyes. Mean age was 10.39 ± 3.81 years for the PBKC group and 10.80 ± 3.61 years for the controls. Mean corrected-distance visual acuity (CDVA) was 0.24 ± 0.21 logMAR in the PBKC group and 0.07 ± 0.1 in the controls (P < 0.001). Mean astigmatism was 1.6 ± 1.98D in the PBKC group vs. 0.67 ± 0.76D in the control group (P = 0.01). Mean RMS of HOAs was 1.05 ± 1.7mm in the PBKC group and 0.41 ± 0.18mm in the controls (P < 0.001). The mean modulation transfer function (MTF) in the PBKC group was significantly lower (16.37 ± 16.32) than controls (30.3 ± 23.57) (P < 0.001). Corneal leukomas, stromal vascularization, peripheral nummular subepithelial scars, and pannus formation are associated with increased HOAs. CONCLUSIONS: There was a significant increase in total HOAs of eyes with PBKC compared to healthy controls. Corneal opacity, vascularization, and scarring are associated with increased HOAs. The PBKC eye aberration profile: coma, secondary astigmatism, quadrafoil, and pentafoil, were associated with decreased CDVA and visual quality (PSF and MTF).

RESUMO

BACKGROUND/AIM: To describe demographic and clinical characteristics, treatment, and visual prognosis of Coats disease in Hispanic patients. METHODS: A retrospective chart review was performed on nine patients (ten eyes) diagnosed with Coats disease in our two clinical centrers from 2004 - 2017. RESULTS: Mean age at diagnosis was 5.5 years (range 1 - 12 years) and mean follow-up time was 48 months (range 9 - 108 months). Eight patients (89%) were male and had unilateral disease and one (11%) female patient had bilateral disease. In 40% of the cases, patients were asymptomatic. Visual acuity at first presentation was worse than hand motion in 60% of the eyes. Half of the eyes (5/10 eyes, 50%) had exudative retinal detachment (≥ stage IIIA). Vascular ablation with cryotherapy combined with retinal photocoagulation was the most frequent therapeutic approach (40%). Despite anatomical success at 6 months in 100% of the treated eyes, visual outcome at 1 year of treatment was poor (worse than 20/200) in 70% of the cases. CONCLUSIONS: In our case series, patients were mostly asymptomatic on presentation, with severe stages of Coats disease. Even with anatomical success after surgical treatment in all treated cases, long-term visual prognosis remained very limited.

RESUMO

INTRODUCTION: Surgical treatment of intermittent exotropia is indicated when periods of monocular deviation become longer or control over deviation deteriorates. However, there is no consensus on the ideal age to perform surgery in patients with intermittent exotropia. PURPOSE: To evaluate ocular alignment and sensory results at 12 months of follow-up, in patients who received surgical treatment for intermittent exotropia at ≤4 years or >4 years. METHODS: A retrospective, observational, analytical, and comparative cohort study was carried out, which included 97 patients treated surgically for X(T), divided into two groups, ≤4 years and >4 years. The motor and sensory results of the patients were evaluated on the first day, 1 month and 12 months of postoperative follow-up. RESULTS: In this study, no statistically significant differences were observed in ocular alignment and postoperative sensory results at 1 year of follow-up between both groups. CONCLUSION: Age is not a variable that influences surgical results in patients with intermittent exotropia. Instead of early or delayed surgery, we propose to use the term "timely surgery."

RESUMO

A 6-hour newborn boy presented with bilateral overriding of the upper eyelids during sleep and spontaneous eyelid eversion. Physical examination revealed canthal tendon laxity and hyperemia of the tarsal conjunctiva of both eyes. A diagnosis of congenital eyelid imbrication syndrome (CEIS) was established. The cornea and remaining adnexal structures were healthy; therefore, conservative management with lubricant ointment was initiated. On day 4, complete resolution of upper eyelid overriding and absence of spontaneous eversion was observed. CEIS is a rare eyelid malposition disorder in which the upper eyelid overrides the lower. Most CEIS cases described in the literature present at birth, occur in Asian patients, are associated with floppy eyelid, and resolve spontaneously. The authors present the first report of CEIS in a Hispanic newborn and a literature review of previously reported cases.
