Purpose/Aim To report the birth prevalence and natural history of congenital corneal opacities among a population-based cohort of children. Materials and methods The medical records of patients <5 years diagnosed with a congenital onset corneal opacity while residing in Olmsted County, Minnesota, from January 1, 1977, through December 31, 2016, were retrospectively reviewed. Results Fourteen patients were diagnosed with a congenital corneal opacity during the 40-year study period for a birth prevalence of 1 in 5188 live births. The mean age at diagnosis was 7.5 months (range 0–48 months) and 9 (64.3%) were males. Four patients had congenital glaucoma, 4 had limbal dermoids, 2 had sclerocornea, and 1 patient each had Descemet's tear from birth trauma, herpes simplex virus type 1 keratitis, corneal leukoma, and an undiagnosed scar. Six (42.8%) patients required treatment for their underlying corneal opacity including the four patients with congenital glaucoma. The other 8 (57.1%) patients had a clear central axis. Four (28.6%) of 14 patients required amblyopia therapy, and 4 (28.6%) developed strabismus. Four (28.6%) patients had associated systemic conditions. During a mean follow up of 5.4 years (range 1.3–27.0 years), the median best corrected visual acuity (BCVA) was logmar 0.16 (20/25) (range 20/20-hand motion) with one patient with unilateral BCVA less than 20/60 and one patient with bilateral BCVA less than 20/60. Conclusions In this 40-year cohort, congenital corneal opacities were relatively rare and the result of a variety of disorders. Although amblyopia and strabismus occurred commonly, most patients had good visual outcomes.

Purpose: The purpose of this retrospective cohort study was to report the outcomes of high AC/A ratio accommodative esotropia (AET) among children. Methods: The medical records of all children <19 years diagnosed with accommodative esotropia and a high AC/A ratio while residing in Olmsted County, Minnesota, from January 1, 1975, through December 31, 2004, were retrospectively reviewed. Results: A total of 512 patients were diagnosed with AET during the 30-year study period, of which 395 (77.1%) had fully accommodative ET, 117 (22.8%) had partially accommodative ET and 106 (20.5%) had a high AC/A ratio. Of the 93 (87.7 %) high AC/A patients managed with bifocals, 50 (53.8 %) discontinued their use after a mean of 58.7 (range: 5.6–229) months. The Kaplan–Meier rate of discontinuing bifocals was 24.5% at 3 years, 36.4% at 5 years, and 61.4% at 10 years. Patients who discontinued bifocals were more likely to have had strabismus surgery (44% vs 18.6%, p = 0.009) than those who did not discontinue bifocals. The high AC/A patients managed with bifocals achieved similar stereoacuity outcomes to those who did not wear bifocals ( p = 0.65) and were no more likely to require surgery ( p = 0.13). Conclusion: Among this cohort of children with accommodative esotropia and a high AC/A ratio, bifocal use was discontinued in the majority of children within 10 years, and more commonly among those who underwent strabismus surgery. The use of bifocals was not associated with a higher likelihood of undergoing surgery or enhanced stereopsis compared to those who did not use them.

Purpose: We sought to evaluate whether additional topical anesthetic, specifically proparacaine 0.5%, improved patient experience with intravitreal injections without hindering antisepsis. Methods: A prospective, randomized controlled trial was conducted including 36 eyes of 36 patients undergoing intravitreal injections. Patients were randomized to treatment with additional topical proparacaine 0.5% versus control after undergoing informed consent. All patients prior to intravitreal injection underwent conjunctival culture after one drop of topical proparacaine 0.5% was placed. Half of patients then received an additional drop of proparacaine and then underwent a second conjunctival culture. The other half of patients had a drop of povidone iodine and then a second conjunctival culture. Intravitreal injection followed conjunctival cultures. To evaluate their experience, patients were provided with a survey. Results: In total, 36 patients were enrolled in the study. Three of 36 (8.3%) patients had positive conjunctival cultures after proparacaine eye drops alone. One of 17 (5.8%) patients had a positive conjunctival culture after a second drop of proparacaine. One of 19 (5.3%) patients had a positive culture after proparacaine and povidone iodine. By noninferiority analysis, proparacaine was inferior to povidone iodine ( p = .28). Patient experience surveys did not differ between groups. Conclusion: Patient perception did not significantly differ whether or not additional proparacaine drops were used prior to intravitreal injection in a randomized controlled trial. While proparacaine has some antiseptic properties, these were found to be inferior to those of povidone iodine. Therefore, while povidone iodine is essential for antisepsis, additional proparacaine drops should not interfere with antisepsis.

Purpose: To describe ophthalmic manifestations of systemic amyloidosis, a group of devastating conditions. Methods: A retrospective chart review including patients who had ocular examinations at Mayo Clinic between January 1, 1985, and April 1, 2014, and a diagnosis of light-chain (AL), secondary (AA), or nontransthyretin familial amyloidosis was undertaken. Sixty-eight patients with AL amyloidosis, eight patients with AA amyloidosis, and five patients with nontransthyretin familial amyloidosis were included. Results: Of 68 patients, 8 patients (14 eyes) with AL amyloidosis had ocular involvement secondary to conjunctiva, temporal artery, extraocular muscle, trabecular meshwork, and cranial nerve deposition. One of the five patients with nontransthyretin familial amyloidosis had gelsolin-related corneal dystrophy. No patients with AA amyloidosis (n = 8) had ophthalmic manifestations. Conclusion: Systemic amyloidosis can lead to ocular morbidity. Patients with AL amyloidosis had involvement of the temporal artery, conjunctiva, extraocular muscles, trabecular meshwork, and cranial nerves. Those with gelsolin nontransthyretin familial amyloidosis were susceptible to corneal dystrophy. Patients with AA amyloidosis did not manifest ophthalmic involvement. Finally, if ocular amyloidosis is detected, patients should be referred for systemic workup.
