[Optic pit maculopathy: incidence and clinical course].
Article in Die Ophthalmologie, 2023. 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
purposeThe aim of this case series was to investigate the clinical course of patients with optic pit maculopathy.
methodsThe medical records of all patients diagnosed with optic pit maculopathy in the past 10 years were reviewed. Optic pit maculopathy was diagnosed when localized intraretinal or/and subretinal fluid spread from the optic nerve to the macula. Outcome measures included changes in best corrected visual acuity (BCVA), central retinal thickness (RT) as well as nasal parafoveal and perifoveal RT.
resultsAn optic disc pit was detected in 18 patients (9 female, 9 male, mean age: 33 ± 23 years). Retinal fluid accumulation was present in 6 (33.3%) of the patients (1 intraretinal, 1 subretinal, 4 intraretinal and subretinal). Pars plana vitrectomy with removal of peripapillary vitreous traction and peeling of the internal limiting membrane (ILM) was indicated in 5 patients and was performed in 4 patients. One patient underwent nanopulse laser treatment instead. The patients with optic pit maculopathy were 47 ± 16 years old. In this group of patients, mean BCVA (decimal) improved from 0.3 ± 0.2 before treatment to 0.5 ± 0.2 3 months after treatment (p = 0.03). Visual acuity improved in all patients with optic disc pit maculopathy after pars plana vitrectomy. The mean central RT decreased from 796 ± 214 before treatment to 324 ± 57 3 months after treatment (p = 0.005). The mean nasal parafoveal RT decreased from 683 ± 87 before treatment to 372 ± 41 (p = 0.0003) and the mean nasal perifoveal RT decreased from 547 ± 89 before treatment to 360 ± 48 (p = 0.007). A completely dry macula was achieved in 4 eyes after a mean follow-up of 3 months. At long-term follow-up (2.5 ± 1.2 years), no recurrence occurred in the vitrectomized eyes.
conclusionThis case series showed that more than one third of the patients had optic pit maculopathy presumably caused by disruption of the Kuhnt intermediate tissue. Interventional treatment was indicated in all cases, of which 4 were surgically treated and resulted in significant improvement of function and anatomical retinal structures.
