Eligibility

Inclusion Criteria:

• Capable to provide informed consent
• Diagnosis of optic neuropathy either glaucoma or NAION or optic disc drusen.
• Only one eye per patient will be selected as the study eye - if both eyes meet the inclusion criteria, the eye with the worse acuity and /or visual field will be selected. The contralateral eye will be left untouched.

Exclusion Criteria:

• Pregnant or breastfeeding woman
• Presence of any ocular pathologies other than glaucoma that contributes to the severe vision loss (retinopathy / maculopathy, severe uveitis, keratopathy, etc.)
• Diagnosis of glucose intolerance, type 1 or 2 diabetes mellitus
• Inability to perform reliable visual field
• Unable to provide informed consent
• Unable to complete the tests and follow-ups required by the study

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants with Treatment-Related Adverse Events	determine the safety of topical sterile human insulin in patients with optic neuropathies. AEs and SAEs will be monitored and recorded through the duration of the study.	During treatment period, difference from baseline to post-treatment up to 2 months
Secondary	Change in retinal thickness measured in microns by spectral domain optical coherence tomography (sdOCT)	The change in retinal thickness as measured by spectral domain optical coherence tomography (sdOCT)	During treatment period, difference from baseline to post-treatment up to 2 months
Secondary	The change in visual field as measured by mean deviation	The change in visual field as measured by mean deviation on Zeiss Humphrey Visual Field testing	During treatment period, difference from baseline to post-treatment up to 2 months
