Purpose: Scanning laser ophthalmoscope (SLO) microperimetry is useful in accurately mapping macular function. We explore the feasibility and potential use of this method in eyes implanted with a Boston keratoprosthesis.

Methods: Retrospective review of eyes with a type I Boston keratoprosthesis tested with OPKO SLO microperimetry. Best-corrected visual acuity, contrast sensitivity and complete slit-lamp and posterior segment examination findings were noted. Visual field and ocular coherence tomography results were collected when available.

Results: Five eyes were included in this study. Mean age was 66 years (range: 54 to 82). Mean LogMAR best-corrected visual acuity was 0.76 (range: 0.30 to 1.20). Contrast sensitivity was decreased in all eyes at a mean of 0.90 log units (range: 0.45 to 1.5). SLO microperimetry could be performed on all 5 eyes. Accurate functional mapping of the macula and preferred retinal locus was obtained in all cases and was not affected by media opacities or decreased contrast sensitivity. The results correlated well with the findings on Goldmann perimetry and OCT in cases in which these were available.

Conclusions: SLO microperimetry through the Boston keratoprosthesis is possible. It is a good adjunct to standard perimetry with involvement of central fixation for accurate macular mapping. It may also allow better assessment of macular pathology unveiled by clearing of the visual axis with a keratoprosthesis.
