| Popis: | A 57-year-old woman presented with photophobia and complaint of a persistent white light in the inferior field of her left eye for 18 months following laser peripheral iridotomy both eyes. In primary gaze, the upper lid margin was noted to bisect the iridotomy at 2 o'clock left eye (OS). She relates that the light moves with her eyelid OS only and resolves by lifting the lid. A 54-year-old male presented with complaint of seeing 2 horizontal lines in his field of vision immediately following laser iridotomy OS that have persisted for a duration of 7 years. He notes they are constant and resolve by lifting up the eyelid. In primary position, the left upper lid margin was noted to bisect the iridotomy at 12 o'clock OS. Given the presence of nonresolving symptomatic dysphotopsia, each patient underwent surgical repair of the iridotomy using a McCannel suture technique with complete resolution of their symptoms. Dysphotopsias are an uncommon complication that can occur following laser peripheral iridotomy. If they persist and conservative measures are ineffective, iris suture repair can provide a definitive intervention in resolving them. Laser iridotomies located in the far periphery pose a surgical challenge with respect to accessibility. A McCannel suture technique provides a feasible approach in suturing them with minimal iris manipulation. Furthermore, it is prudent to assess the upper lid position in primary gaze before creating an iridotomy in order to avoid interference with the lid margin tear film meniscus that can lead to the formation of symptomatic dysphotopsia. |
