ABSTRACT
ABSTRACT

Purpose:

Evaluation of the nerve fiber thicknesses of the macula, choroid, and retina using the apnea-hypopnea index in individuals with obstructive sleep apnea syndrome (OSAS) without systemic components.

Methods:

Prospective, controlled study. The central macular, choroidal, and retinal nerve fiber layer (RNFL) thicknesses were evaluated using enhanced depth imaging-spectral domain optical coherence tomography in individuals with OSAS. In people with severe OSAS who had received treatment, posterior ocular structures were examined over 3 months (4th and 12th weeks), and changes were evaluated. Only the right eyes of the participants were evaluated in the study.

Results:

A total of 72 people were involved in the study, with 18 in the control group and 19 with mild, 16 with moderate, and 19 with severe OSAS. No significant difference was found among the groups in terms of demographic measures. No significant differences were found among the groups in terms of the measures of central macular, central subfoveal choroidal (CSCT), temporal choroidal, nasal choroidal, and RNFL thicknesses. In severe OSAS cases in which treatment was administered, although subjective clinical recovery was observed, statistically significant thinning was detected during the 3-month follow-up period in the CSCT, general RNFL, as well as in the inferior and superior nasal quadrants, and temporal superior quadrant (p=0.005, p=0.009, p=0.039, p=0.003, and p=0.02, respectively).

Conclusion:

In the group with severe OSAS, thinning in some posterior ocular tissues was observed. Although patients with severe OSAS may experience clinical recovery, we recommend that they would be followed up in terms of ocular ischemic injury.
RESUMO
RESUMO

Objetivo:

Avaliação de espessuras das fibras nervosas da mácula, coroide e da retina de acordo com os índices de apnéia e hipopnéia (AHI) em indivíduos com síndrome da apneia obstrutiva do sono (OSAS), sem componentes sistêmicos.

Métodos:

Estudo prospectivo, controlado. As espessuras centrais maculares, da coroide e da camada de fibras nervosas da retina foram avaliadas tomografia de coerência óptica de domínio espectral de profundidade aprimorada em indivíduos com síndrome da apneia obstrutiva do sono. Em pessoas com OSAS grave a quem foi aplicado o tratamento, estruturas oculares posteriores foram examinados por três meses (4ª e 12ª semanas) e as alterações foram avaliadas. Apenas os olhos direitos dos participantes foram envolvidos no estudo.

Resultados:

72 pessoas foram envolvidas no estudo, 18 no grupo controle e, 19 com OSAS leve, 16 com OSAS moderada e 19 com OSAS grave. Não houve diferença significativa entre os grupos em relação às medidas demográficas. Não houve diferenças significativas estavam presentes entre os grupos em termos de medidas de espessura macular central (CMT), espessura subfoveal central da coroide (CSCT), espessura da coroide temporal (TCT), espessura da coroide nasal (NCT) e, a camada de fibras nervosas da retina (RNFL). Em casos de OSAS graves onde o tratamento foi aplicado, apesar de ter sido observada recuperação clínica subjetiva, detectou-se afinamento estatisticamente significativo durante os três meses de acompanhamento, em CSCT, RNFL geral, quadrantes nasais inferior e superior, e quadrante temporal superior (p=0,005, p=0,009, p=0,039, p=0,003, p=0,02).

Conclusão:

No grupo com OSAS grave, foi observado afinamento em algumas áreas posteriores dos tecidos oculares. Embora os pacientes com OSAS grave possam apresentar recuperação clínica, recomendamos que eles sejam seguidos em termos de lesão isquêmica ocular.
