Total recovery of visual acuity in a pediatric patient with compressive optic neuropathy secondary to sphenoid sinus mucocele / Recuperação total da acuidade visual na neuropatia óptica compressiva secundária à mucocele do seio esfenoidal em paciente pediátrico

ABSTRACT We present an unusual case of a 13-year-old male pediatric patient with a diagnosis of sphenoid sinus mucocele. The patient suffered a progressive loss of visual acuity over three months followed by a total recovery of his visual acuity after surgery. The patient presented at the emergency room complaining of progressive loss of visual acuity in his left eye which decreased to hand motion over the preceding months. Imaging studies revealed a cystic mass, suggestive of sphenoid sinus mucocele, which was causing compressive optic neuropathy and proptosis. The patient was scheduled for a sphenoidectomy and resection of the mass. Three days after surgery, the patient's visual acuity in the left eye was 20/20, indicating complete recovery from his symptoms. We suggest that the excellent outcome in this patient may be attributable to his age. His ongoing physical development might have been the decisive factor in the recovery of his visual acuity following compressive optic neuropathy secondary to sphenoid sinus mucocele. Further research is needed to verify this proposed explanation.

RESUMO Apresentamos um caso incomum de paciente pediátrico com diagnóstico de mucocele de seio esfenoidal, que apresentou perda progressiva da acuidade visual ao longo de três meses, resultando em recuperação total da acuidade visual após a cirurgia. Paciente do sexo masculino, 13 anos, procurou o pronto-socorro, queixando-se de perda progressiva da acuidade visual do olho esquerdo nos últimos três meses. Exames de imagem revelaram uma massa cística sugestiva de mucocele de seio esfenoidal, causando neuropatia óptica compressiva e proptose. O paciente foi agendado para esfenoidectomia e ressecção da massa. Três dias após a cirurgia, a acuidade visual do paciente no olho esquerdo era de 20/20, apresentando recuperação completa dos sintomas. Diante dos resultados de nosso paciente, sugerimos que a idade do paciente pode ser decisiva na recuperação da acuidade visual de uma neuropatia óptica compressiva secundária à mucocele de seio esfenoidal. Mais pesquisas são necessárias para verificação desses dados.

Total recovery of visual acuity in a pediatric patient with compressive optic neuropathy secondary to sphenoid sinus mucocele.

We present an unusual case of a 13-year-old male pediatric patient with a diagnosis of sphenoid sinus mucocele. The patient suffered a progressive loss of visual acuity over three months followed by a total recovery of his visual acuity after surgery. The patient presented at the emergency room complaining of progressive loss of visual acuity in his left eye which decreased to hand motion over the preceding months.

Less is more: new one-step intracameral chemotherapy technique.

Purpose: To describe the feasibility of a new one-step approach to aspirate the aqueous and apply melphalan in a single-go without repeated entries into the anterior chamber. Methods: This retrospective non-comparative study was conducted at a referral center and included 12 patients. The one-step approach is described in a step-wise manner. No complications were observed among the patients. Results: One single injection of intracameral melphalan proved to be a successful treatment in nine cases. Two patients required a second injection, which was administered two weeks after the first one following the same technique. Conclusions: This proved to be a reasonable technique for the smooth application of melphalan in the anterior chamber studded with retinoblastoma seeds. Our outcomes revealed that it is an effective, quick, and cost-effective technique. Longer-term data collection is underway, though initial findings are encouraging.

Plug the pit: a surgical technique for optic disc pit.

Purpose: To present a recently described surgical technique for the treatment of optic disc pit (ODP) and evaluate its outcomes. Methods: A patient presented with refractory serous macular detachment and secondary full thickness macular hole associated with ODP, for which he had already undergone pars-plana vitrectomy with internal limiting membrane peeling and autologous serum application over the optic disc pit. A recently described surgical technique was carried out to treat this case. In this procedure, a silicone punctal plug was used to close the ODP. The macular hole was closed with a human amniotic membrane graft. Endotamponade was carried out with 1000cs silicone oil. Results: Postoperatively, the serous macular detachment subsided and the punctal plug and amniotic membrane graft were in situ. Patient's visual acuity improved from counting fingers to 6/38 at one year postoperative. Conclusion: This technique appears to be safe and effective in resolving long standing serous macular detachment associated with ODP, which was refractory to the conventional intervention. However, more cases and longer follow-ups are needed to affirm the safety and efficacy of this recently described procedure.
