3048: Dense Cataract and Dense Amblyopia
Performing cataract surgery on an eye with profound anisometropic amblyopia and a predicted visual potential limited to counting fingers is justified when media opacification blocks essential vitreoretinal surveillance. In an eye with an extreme axial length of 36 mm, the risk for peripheral lattice degeneration, staphyloma-associated pathology, and retinal tears or detachments is high; clearing the visual axis becomes a diagnostic and therapeutic necessity rather than a purely refractive goal. The decision to proceed with surgery becomes imperative as soon as the dense, brunescent cataract obscures a reliable view of the fundus, preventing adequate indirect ophthalmoscopy or optical coherence tomography. Utilizing Manual Shelved Incision Cataract Surgery (MSICS) allows for the safe manual extraction of a rock-hard nucleus while avoiding excessive phacoemulsification energy in a deep, highly myopic anterior chamber. The patient also has Heavy Eye Syndrome – a rare condition where there is induced esotropia and hypotropia. Watch the video to analyze the strategic surgical decision-making and manual nuclear delivery required in this high-risk, highly myopic eye. At what threshold of visual impairment or fundus view degradation do you recommend proceeding with cataract surgery in heavily amblyopic eyes? Please comment your thoughts below.
