Postoperative outcomes in mitochondrial myopathy-associated ptosis: a case series.
Article in International ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo determine the anatomical and functional success and complication rates after surgical treatment in cases of mitochondrial myopathy (MM) with ptosis and how the complications that develop may be managed.
methodsPatients who underwent surgical correction due to ptosis between October 2010 and January 2020 and diagnosed with MM on muscle biopsy were retrospectively analyzed. The margin reflex distance 1 (MRD1) values of the patients were evaluated preoperatively, postoperative 1st week, 1st month, 6th month and 12th month. The complications that developed during the follow-ups and their management were examined.
resultsThe study included 64 eyes of 34 patients. In all patients, the MRD1 value at 1 week, 1 month, 6 months, and 12 months after the surgery showed a significant increase compared to the preoperative value (p < 0.05). Lagophthalmic keratitis developed in 1 eye (1.56%) that underwent levator resection and healed without sequelae. In 1 eye (1.56%) that underwent silicone frontal sling, lagophthalmic keratitis and inferior corneal ulcer developed, healed with minimal corneal haze and did not affect visual acuity. A corneal ulcer developed in 1 eye (1.56%) that underwent levator resection 12 months later due to insufficient lubricant treatment and healed with minimal corneal haze without causing vision loss with frequent topical lubricant and topical antibiotics. One of the two patients who underwent levator resection had ptosis progression in one eye after 18 months and the other in one eye after 24 months. Surgical revision was not required.
conclusionsComplications related to lagophthalmos may be prevented with the appropriate patient and surgical method selection and frequent postoperative observation. Early intervention in developing complications may also prevent serious complications that cause visual sequelae.
