Giant Fornix Syndrome: How Much Conjunctiva Should Be Resected?

Abstract

To characterize clinical profiles of Chinese patients with giant fornix syndrome (GFS), compare surgical outcomes with amount of Müller's muscle-conjunctival resection (MMCR), and elicit risk factors for those who have prolonged recovery after MMCR. Retrospective, observational, interventional cohort study on GFS eyes. Two treatment groups were established: limited MMCR-as defined by 8 mm or less resection; maximal MMCR-as defined by 10-12 mm resection. Good responders were defined as eyes exhibiting disease resolution within 3 months after surgery. Primary outcome was disease resolution, secondary outcome was ptosis improvement. Mean age was 81.9 years old (range, 76-89), with 6 (75%) females and 2 (25%) males. All 10 eyes presented with discharge, partial ptosis, and conjunctival injection. In the limited MMCR group, time to symptom resolution was longer at 5.56 months, while maximal MMCR group was 2.02 months (p = 0.004). Limited MMCR group also had lower primary surgical success and required additional surgery compared with maximal MMCR group (p = 0.008). At mean follow up of 34.4 months (range, 11-65 months), all eyes achieved disease resolution, no recurrence, and ptosis improvement. In the largest series on Chinese eyes with GFS to date, GFS is mainly a disease in elderly females. Maximal MMCR has a higher rate of surgical success with no additional complications. For those who underwent MMCR, additional treatment such as topical steroids and fortified antibiotics do not affect time to recovery. These findings may help ophthalmologists consider maximal MMCR as a definitive surgical treatment in GFS eyes.
