ABSTRACT
ABSTRACT

Purpose:

To evaluate the association between macular hole volume (MHV) and postoperative central macular thickness (CMT) using spectral-domain optical coherence tomography (SD-OCT).

Methods:

Thirty-three eyes of 30 patients with a large full-thickness idiopathic macular hole with or without vitreomacular traction who underwent surgical intervention were included in this cross-sectional study. Complete ophthalmological examination, including SD-OCT, was performed for all participants during the pre- and postoperative visits. MHV was preoperatively measured using SD-OCT, which captured the widest cross-sectional image of the hole. For normal distribution analysis of the data, the Kolmogorov-Smirnov test was performed, and for statistical analyses, chi-square, Student's t-test, Mann-Whitney U test, and Pearson's correlation coefficient test were performed.

Results:

Mean preoperative best-corrected visual acuity (BCVA) and MHV were found to be 0.99 ± 0.36 (range, 0.3-2.0) logMAR and 0.139 ± 0.076 (range, 0.004-0.318) mm3, respectively. Mean follow-up was 16.3 ± 14.3 (range, 3-50) months. No statistical correlations were found between MHV and postoperative BCVA (p=0.588) and between MHV and disease recurrence (p=0.544). A weak negative correlation existed between MHV and final CMT scores (p=0.04, r=-0.383).

Conclusions:

Greater MHV was found to be weakly associated with lower postoperative CMT scores.
RESUMO
RESUMO

Objetivo:

Avaliar a relação entre o volume do buraco macular (MHV) e a espessura macular central pós-operatória (CMT) por meio da tomografia de coerência óptica de domínio espectral (SD-OCT).

Método:

Trinta e três olhos de 30 pacientes com buracos maculares idiopáticos de espessura total grandes, com ou sem tração vitreorretiniana, que foram submetidos a intervenção cirúrgica foram incluídos neste estudo transversal. O exame oftalmológico completo, incluindo SD-OCT foi realizado nas visitas pré e pós-operatórias de todos os participantes. MHV foi medido a partir da imagem de SD-OCT pré-operatória que capturou a imagem mais larga da secção transversal do buraco. Após a análise distribuição nomral da população do estudo ter sido realizada com o teste Kolmogorov-Smirnov, os testes de qui-quadrado, t de Student, Mann-Whitney U e teste de correlação de Pearson foram utilizados para as estatísticas.

Resultados:

As médias pré-operatórias da melhor acuidade visual corrigida (BCVA) e MHV foram 0,99 ± 0,36 logMAR (variação de 0,3-2,0) e 0,139 ± 0,076 mm3 (variação de 0,004-0,318). O seguimento médio foi de 16,3 ± 14,3 meses (variação de 3-50). Não foram encontradas correlações estatísticas entre MHV e BCVA pós-operatória (p=0,588), bem como MHV e recorrência da doença (p=0,544). Uma fraca correlação negativa estava presente entre MHV e pontuações finais CMT (p=0,04, r=-0,383).

Conclusões:

Maior MHV foi fracamente relacionado com CMT mais baixo, no pós-operatório.
