Brief Summary:
Telemedicine allows screening of subjects with limited access to eye care. Failure of screenees to come for full examination was identified as a serious problem. Teleglaucoma should allow a single physician access to screenees in real time. The investigators aim to test the technical feasibility of developing a system for teleglaucoma that will allow a physician real time access to patient information and images and compare it to traditional physical presence evaluation in glaucoma clinics. This system can be applied during telemedicine for glaucoma and other vision threatening diseases.

Intervention Details:
  • Diagnostic Test: Teleglaucoma
    Subjects are evaluated through a teleglaucoma protocol then by physical presence in a glaucoma clinic
    Other Name: teleophthalmology

Primary Outcome Measures :
  1. Comparison of diagnosis and management in Teleglaucoma and conventional care [ Time Frame: 24 months ]

    Qualitative categorical outcome:

    Glaucoma Diagnosis, Management and follow up are clinical determinations by the investigator that are based on the overall clinical evaluation of the subject

    Diagnosis: A. no glaucoma B. confirmed glaucoma

    Management: A. maintain current therapy, B. advance therapy (additional glaucoma medication or surgical glaucoma intervention), C. no therapy needed

    Follow up: A. urgent (less than 4 weeks from time of evaluation) B. routine (more than 4 weeks from time of evaluation)

Secondary Outcome Measures :
  1. Assessment of diagnostic tools during teleglaucoma: Visual acuity [ Time Frame: 12 months ]

    Quantitative outcome:

    Visual Acuity will be measured on the Snellen chart and then converted to a Log MAR scale (Logarithm of the Minimal Angle of Resolution scale= Log MAR scale). Log MAR scale:

    0.0 to 2.0 units (in increments of 0.2) with 0.0 units representing 20/20 visual acuity (normal vision) and higher numbers representing worse visual acuity (2.0 units representing poor vision of 20/2000)

  2. Assessment of diagnostic tools during teleglaucoma: Tonometry [ Time Frame: 12 months ]

    Quantitative outcome:

    Tonometry will be measured using a Goldmann applanation tonometer and a puff tonometer. All measurements will be in mm Hg, range 0.0-60.0 mm Hg (in increments of 1 mm Hg). Normal range is 6-21 mm Hg. Measurements below 6 and above 21 mm Hg are considered outside the normal range.

  3. Assessment of diagnostic tools during tele glaucoma: Optic nerve [ Time Frame: 12 months ]

    Quantitative outcome:

    Vertical and Horizontal cup-to-disc rations 0.0-1.0 (in increments of 0.1) will be measured. Ratio>0.6 are considered higher risk for glaucoma.

    All measurements will be made by investigators on a high resolution monitor in a dark room. Investigators will be masked to one another assessments in instances were multiple readings are obtained. Images will be presented in a random order when multiple measures are obtained. Other Anterior and posterior segment pathology will be qualitatively noted (cataract, narrow angle, cornea pathology, diabetic retinopathy, age related macular degeneration, other).

  4. Assessment of diagnostic tools during tele glaucoma: Optical Coherence Tomography [ Time Frame: 12 months ]

    Quantitative outcome:

    Optical Coherence Tomography (OCT) will be used to obtain images of the anterior and posterior ocular segments.

    Quantitative measures in micron: 0-900 micron (+/- 5 micron) will be recorded for the cornea, optic nerve and retina. The range of normal is based on reference data that is age and racially determined.
