Surgical treatment outcomes in heavy eye syndrome - a case series
Introduction
This study presents the effectiveness of a surgical intervention for heavy eye syndrome, an infrequent condition associated with high myopia. Heavy eye syndrome is characterized by a progressive, large-angle esotropia and hypotropia, leading to limited abduction and supraduction of the affected eye.
Methods
Conducted at Unidade Local de Saúde de Matosinhos, Portugal, between 2017 and 2021, this retrospective study includes five patients diagnosed with heavy eye syndrome. The comprehensive dataset collected for each patient includes demographic information, clinical parameters, and detailed orthoptic evaluations, along with MRI imaging for visualizing orbital anatomy. The surgical procedure involved partial splitting and scleral fixation of the superior rectus (SR) and lateral rectus (LR) muscles, with retroequatorial myopexy of the medial rectus (MR) muscle in cases of abduction restriction.
Results
The study cohort consisted of five patients with unilateral high axial myopia and classic heavy eye syndrome features, including large-angle esotropia, hypotropia, and restricted eye movement. MRI imaging revealed superotemporal globe prolapse, with a mean angle of dislocation of 135.7 degrees, contributing to limited eye movement. After surgery, all patients showed significant improvements in vertical and horizontal deviations, addressing primary clinical manifestations. Photographic documentation confirmed substantial improvements in ocular alignment.
Conclusions
In managing heavy eye syndrome associated with high myopia, various surgical approaches have been explored with mixed results. This study's technique of partial muscle splitting, scleral fixation, and MR retroequatorial myopexy offers a promising approach to address this challenging condition effectively. These findings suggest that this surgical technique is a safe and effective option for managing heavy eye syndrome, providing cosmetic and functional improvements to affected individuals.
