Two birds, one stone: a surgical approach for third nerve palsy with aberrant regeneration / Tratamento cirúrgico de paralisia de terceiro nervo craniano com regeneração aberrante

ABSTRACT Aberrant regeneration in third nerve palsies, linking medial rectus contraction to the levator palpebrae muscle, is a great opportunity for surgical planning to address both the ptosis and horizontal deviation in a single procedure. We report a case of severe ptosis associated with exotropia that was successfully corrected with a single horizontal strabismus surgery owing to aberrant regeneration and discuss the basis underlying the surgical planning.

RESUMO A regeneração aberrante nas paralisias do terceiro nervo, ligando a contração do reto medial ao músculo levantador da pálpebra, é uma grande oportunidade para fazer um planejamento cirúrgico para tratar tanto a ptose quanto o desvio horizontal em um procedimento único. Relatamos uma ptose grave associada à exotropia corrigida com sucesso com uma única cirurgia de estrabismo horizontal devido à regeneração aberrante e discutimos as bases do planejamento cirúrgico.

Two birds, one stone: a surgical approach for third nerve palsy with aberrant regeneration.

Aberrant regeneration in third nerve palsies, linking medial rectus contraction to the levator palpebrae muscle, is a great opportunity for surgical planning to address both the ptosis and horizontal deviation in a single procedure. We report a case of severe ptosis associated with exotropia that was successfully corrected with a single horizontal strabismus surgery owing to aberrant regeneration and discuss the basis underlying the surgical planning.

Bilateral superior oblique temporal tenectomy for the treatment of A-pattern strabismus.

PURPOSE: To assess the efficacy of superior oblique temporal tenectomy 6.0 mm from its insertion to treat A-pattern strabismus of all magnitudes. METHODS: The clinical records of patients with A-pattern eso- or exotropia associated with bilateral superior oblique overaction who underwent bilateral superior oblique 6.0 mm temporal tenectomy at a single institution over a 17-year period were reviewed retrospectively. Outcome measures were change in the A pattern and correlation with preoperative A pattern. RESULTS: A total of 102 patients were included. The mean preoperative A-pattern deviation was 21Δ ± 9Δ, with a postoperative pattern collapse of 18Δ ± 10Δ. Change in A pattern was significantly correlated with the preoperative A pattern (r = 0.70; P <0.001). In patients with an A pattern of ≥25Δ, the preoperative deviation was 31Δ ± 7Δ, with a postoperative pattern collapse of 27Δ ± 9Δ. In 76% of patients with A pattern of <25Δ and in 72% of patients with A pattern ≥25Δ, the A pattern was corrected to <10Δ. The average percentage of A pattern correction was 89% in patients with pattern deviation <25Δ and 86% in patients with pattern deviation ≥25Δ. CONCLUSIONS: In our study cohort, bilateral superior oblique temporal tenectomy was an effective and self-adjusting procedure for A-pattern strabismus associated with superior oblique overaction. Larger preoperative A patterns did not show a significant trend toward larger residual postoperative deviations compared with smaller preoperative patterns. A uniform dose of bilateral superior oblique temporal tenectomy collapses A patterns of all magnitudes.

Why ophthalmology? Analysis of the motivating factors influencing the choice of ophthalmology as a career among different generations in Brazil.

OBJECTIVES: The increasing demand for medical specialties with flexible working hours has been associated with the important role of quality of life as a determining factor when choosing a career in medicine, which might change the motivations for pursuing a career in ophthalmology. We aim to identify the main determinants of ophthalmology as a career choice as well as the reasons that motivated previous generations to follow this path. METHODS: Responses to self-administered online questionnaires were analyzed. RESULTS: A total of 225 responses were analyzed, including those of baby boomers (21), generation X (48), generation Y (131) and generation Z (25). Although the main reasons for choosing ophthalmology as a career are the same for all the generations in this study (flexible working hours, self-satisfaction from helping people improve their vision and the possibility of performing surgical procedures), some reasons for this career choice are more important to the younger generations (short-term results and short procedures), and some are more important to the older generations (the influence of an ophthalmologist in the family). CONCLUSION: The main reasons for choosing ophthalmology as a career are essentially the same over time. The differences in secondary motivations could be explained by generational differences.

Acute Hemorrhagic Edema of Infancy: an unusual diagnosis for the general pediatrician.

Acute Hemorrhagic Edema of Infancy (AHEI) is a rare leukocytoclastic vasculitis, clinically characterized by the classical triad: palpable purpuric skin lesions, edema and fever, and is commonly misdiagnosed as Henoch-Schönlein purpura. In addition to its sudden onset, AHEI is also characterized by its self-limited course with complete and spontaneous recovery occurring between 1 and 3 weeks. Because of the scarcity of studies on therapy with corticosteroids, the conservative approach is usually recommended. The authors report an unusual case of an one-year-old boy who presented with typical cutaneous rash of AHEI and orchitis, the latter showing complete resolution after less than 24 hours of prednisolone therapy. The authors call attention to this entity mainly as a differential diagnosis of Henoch-Schönlein purpura and to the importance of new studies to establish the benefits of corticosteroid therapy for AHEI.
